     CERTIFICATE OF DETERMINATION OF THE RIGHTS, PREFERENCES, PRIVILEGES AND
                                  RESTRICTIONS
                           OF SERIES B PREFERRED STOCK
                                       OF
                               GREATER BAY BANCORP

The undersigned, David L. Kalkbrenner and Linda M. Iannone, hereby certify that:

         1. They are the President and Secretary, respectively, of Greater Bay
Bancorp, a corporation organized and existing under the laws of the State of
California (the "Corporation").

         2. The Restated Articles of Incorporation of the Corporation authorize
the Board of Directors to designate 4,000,000 shares of preferred stock, and to
issue such preferred shares in one or more series from time to time.

         3. The board of directors has previously designated 1,200,000 shares as
Series A Preferred Stock, none of which have been issued.

         4. That, pursuant to authority conferred upon the board of directors of
the Corporation by the Restated Articles of Incorporation of the Corporation,
and pursuant to the provisions of Section 202 of the General Corporation Law of
the State of California, the board of directors has adopted resolutions on
December 18, 2001, providing for the determination, designation and issuance of
2,400,000 shares of Series B Preferred Stock, none of which have been issued,
which resolutions are as follows:

         WHEREAS, Article III (b) of the Restated Articles ("Articles")
authorizes the board of directors to designate any and all of the shares of
Preferred Stock;

         WHEREAS, the board of directors has determined that designating
2,400,000 shares of Series B Preferred Stock would be in the best interests of
the Corporation and its shareholders; and

         WHEREAS, the Series B Preferred Stock shall have the rights,
preferences, privileges and restrictions set forth below.

         NOW, THEREFORE, BE IT RESOLVED, that the board of directors designates
2,400,000 shares of the Preferred Stock as Series B Preferred Stock in accord
with Article III of the Articles.

         RESOLVED FURTHER, that the Series B Preferred Stock shall have the
following rights, preferences, privileges and restrictions and that defined
terms used hereinafter have the meanings ascribed to them in the Articles:

                                       1



         The rights, preferences, privileges and restrictions, designation and
number of shares of the Series B Preferred Stock are as follows:

         Section 1.     Designation, Amount and Ranking.
                        -------------------------------

         (A) The number of authorized shares constituting Series B Preferred
Stock is 2,400,000. The shares of Series B Preferred Stock shall have a stated
value of $50.00 per share (the "Stated Value"). No fractional shares of Series B
Preferred Stock will be issued. The number of authorized shares of Series B
Preferred Stock may be increased or reduced (but not below the number of such
shares then outstanding) by resolution duly adopted by or pursuant to authority
conferred by the board of directors without shareholder vote as authorized by
Section 203.5 of the CGCL (as defined in Section 11 below).

         (B) The Series B Preferred Stock shall rank, with respect to dividend
preference and rights as enumerated in Section 2 below and liquidation
preference and rights as enumerated in Section 5 below, senior to the Common
Stock and senior to all other classes or series of capital stock of the
Corporation now or hereafter authorized, other than any class or series of
capital stock designated as ranking on parity with or senior to the Series B
Preferred Stock as to dividend rights and rights on liquidation.

         Section 2.     Dividend Rights; Payment of Dividends.
                        -------------------------------------

         (A) Subject to the terms of this Section 2, the holders of shares of
Series B Preferred Stock shall be entitled to receive, when, as, and if declared
by the board of directors, out of funds legally available for payment, for each
share of Series B Preferred Stock noncumulative cash dividends, payable
quarterly in arrears, at the rate of 7.25% per annum of the per share Stated
Value thereof. Such noncumulative dividends, when declared on the Series B
Preferred Stock, shall accrue from the original Issue Date (as defined in
Section 11 below) or the date immediately succeeding the most recent Series B
Dividend Payment Date (as defined below) and be payable, if declared, quarterly
on the last day of March, June, September and December of each year that any
shares of the Series B Preferred Stock remain outstanding (each of such dates, a
"Series B Dividend Payment Date" whether or not a dividend is paid on such
date); provided, however, that if such day is not a Business Day ( as defined in
       --------  -------
Section 11 below), the Series B Dividend Payment Date shall be the immediately
preceding Business Day with the same force and effect as if made on the date
such payment was originally payable. Each declared dividend shall be payable to
holders of record as they appear on the stock books of the Corporation at the
close of business on such record dates, which shall be not more than 30 calendar
days and not less than 10 calendar days preceding the payment dates therefor, as
determined by the board of directors or a duly authorized committee thereof
(each of such dates, a "Record Date"). Quarterly dividend periods (each a
"Dividend Period") shall commence on and include the first day of January,
April, July, and October of each year and shall end on and include the
immediately succeeding Series B Dividend Payment Date; provided, however, that
the first Dividend Period shall commence on and include the Issue Date and end
on and include the immediately succeeding Series B Dividend Payment Date.
Dividends payable on the Series B Preferred Stock for any period less than a
full Dividend Period shall be computed on the basis of

                                       2



a 360-day year consisting of twelve 30-day months. Dividends payable on the
Series B Preferred Stock for each full Dividend Period shall be computed by
dividing the annual dividend rate by four. The Series B Preferred Stock shall
not participate in dividends with the Common Stock or Series A Preferred Stock.
Holders of the Series B Preferred Stock shall not be entitled to any dividends,
whether payable in cash, property or stock, in excess of declared noncumulative
dividends, as herein provided, on the Series B Preferred Stock. No interest or
sum of money in lieu of interest shall be payable in respect of any declared
dividend payment or payments on the Series B Preferred Stock.

         (B) The right of holders of the Series B Preferred Stock to receive
dividend payments is not cumulative so that if the board of directors fails to
declare a dividend payable on a Series B Dividend Payment Date in respect of the
Series B Preferred Stock, then the right of holders of Series B Preferred Stock
to receive a dividend in respect of the Dividend Period ending on such payment
date will be lost, and the Corporation shall have no obligation to pay a
dividend in respect of such Dividend Period or to pay any interest thereon,
whether or not dividends on the Series B Preferred Stock are declared and
payable on any future Series B Dividend Payment Dates.

         (C) Full dividends on the Series B Preferred Stock must be declared and
paid or set apart for payment for the current Dividend Period before (i) any
dividends or other distributions (other than dividends or distributions paid in
shares of, or in options, rights, or warrants to subscribe for, or purchase
shares of, Common Stock or any capital stock of the Corporation ranking junior
to the Series B Preferred Stock as to dividend rights and rights on liquidation)
on Common Stock or any other capital stock of the Corporation ranking junior to
the Series B Preferred Stock as to dividend rights and rights or liquidation may
be declared and paid or set aside or (ii) any Common Stock or any other capital
stock of the Corporation ranking junior to or on parity with the Series B
Preferred Stock as to dividend rights or rights on liquidation may be redeemed,
purchased or otherwise acquired for any consideration (or any moneys may be paid
to or made available for a sinking fund for the redemption of any of such
shares) by the Corporation (except by conversion into or exchange for shares of
capital stock of the Corporation ranking junior to the Series B Preferred Stock
as to dividends rights and rights on liquidation and pursuant to rights granted
under the Corporation's 1996 Stock Option Plan, as amended, Stock Purchase Plan,
as amended and similar employee stock plans hereafter adopted), otherwise, in
the case of the Series B Preferred Stock and any other capital stock of the
Corporation ranking on parity with the Series B Preferred Stock as to dividend
rights and rights on liquidation, than pursuant to pro rata offers to purchase,
or a concurrent redemption of all, or a pro rata percent, of the outstanding
Series B Preferred Stock and any other capital stock of the Corporation ranking
on parity with the Series B Preferred Stock as to dividend rights and rights on
liquidation.

         (D) When dividends for any Dividend Period are not paid in full, as
provided in paragraph (C) of this Section 2, on the shares of the Series B
Preferred Stock or any shares ranking equally with the Series B Preferred Stock
as to dividend rights and rights on liquidation, dividends may be declared and
paid on any such preferred shares for any dividend period therefore, but only if
such dividends are declared and paid pro rata so that the amount of dividends
declared and paid per share on the shares of the Series B Preferred Stock and
any such equally ranking shares of preferred stock, in all cases shall bear to
each other the same ratio that

                                       3



the amount of unpaid dividends per share on the shares of the Series B Preferred
Stock for such Dividend Period and such equally ranking shares of preferred
stock for the corresponding dividend period bear to each other.

         (E) Any series of preferred stock or other capital stock ranking on a
parity as to dividend rights with the Series B Preferred Stock issued by the
Corporation shall only have dividend periods which end on the same dates as the
Dividend Periods.

         Section 3.     Voting Rights.  The  holders of the Series B Preferred
                        --------------
Stock  shall not be entitled to any voting  rights, except to the extent, if
any, required by applicable law or as set forth below in this Section 3.

         (A) Except as otherwise provided in paragraphs (B), (C) and (D) of this
Section 3, and so long as any shares of the Series B Preferred Stock are
outstanding, each share of Series B Preferred Stock shall entitle the holder
thereof to vote on all matters voted on by holders of Common Stock voting
together as a single class with the Common Stock and any other shares entitled
to vote on matters voted on by holders of the Common Stock as a single class.
With respect to any such vote, each share of Series B Preferred Stock shall
entitle the holder thereof to cast the number of votes equal to the number of
votes which could be cast in such vote by a holder of the shares of capital
stock of the Corporation into which such share of Series B Preferred Stock is
convertible on the record date for such vote; provided, however, that if more
                                              --------  -------
than one share of Series B Preferred Stock shall be held by any holder of shares
of Series B Preferred Stock, the total number of votes which such holder shall
be entitled to cast pursuant to this Section 3(A) shall be computed on the basis
of conversion of the total number of shares of Series B Preferred Stock held by
such holder, with any then remaining fractional share disregarded for the
purposes of this Section 3(A).

         (B) (i)    So long as any shares of Series B Preferred Stock are
         outstanding, the Corporation shall not, without the consent or vote of
         the holders of at least a majority of the outstanding shares of the
         Series B Preferred Stock, voting separately as a class, in person or by
         proxy, amend, alter or repeal or otherwise change any provision of this
         Certificate of Determination, except to increase the authorized number
         of shares of Series B Preferred Stock as may be necessary to carry out
         the provisions of the Agreement and Plan of Merger and Reorganization
         dated December 18, 2001 among the Corporation, GBBK Corp. and Alburger
         Basso de Grosz Insurance Services, Inc. (which increase the Corporation
         shall authorize as may so be necessary).

              (ii)  So long as any shares of Series B Preferred Stock are
         outstanding, the Corporation shall not, without the consent or vote of
         the holders of at least a majority of the outstanding shares of the
         Series B Preferred Stock, voting separately as a class, in person or by
         proxy, amend, alter or repeal or otherwise change any provision of its
         Restated Articles of Incorporation, other than this Certificate of
         Determination, if such amendment, alteration or repeal would adversely
         affect the rights, preferences, powers or privileges of the Series B
         Preferred Stock.

             (iii)  Without limiting the amendments, alterations, or repeal of
         provisions of the Restated Articles of Incorporation that would not
         adversely affect the rights,

                                       4



          preferences, powers or privileges of the Series B Preferred Stock, an
          amendment, alteration, or repeal of or to any provision of the
          Restated Articles of Incorporation which (1) increases the number of
          authorized shares of Preferred Stock or (2) creates, authorizes or
          provides for the issuance of any capital stock ranking junior to or on
          parity with the Series B Preferred Stock as to dividend rights and
          rights on liquidation of the Corporation shall not be considered to be
          an adverse change requiring a vote of the holders of the Series B
          Preferred Stock pursuant to this Section 3(B).

               (iv) For a period of three years after the Issue Date, so long as
          any shares of Series B Preferred Stock are outstanding, the
          Corporation shall not, without the consent or vote of the holders of
          at least a majority of the outstanding shares of the Series B
          Preferred Stock, voting separately as a class, in person or by proxy,
          amend the Restated Articles of Incorporation or adopt a certificate of
          determination to create, authorize or provide for the issuance of any
          capital stock with both the right to receive cumulative cash dividends
          and the right to convert such security into the Common Stock of the
          Corporation, whether such security is senior to, junior to or on
          parity with the Series B Preferred Stock as to dividend rights and
          rights on liquidation.

         (C) Except as otherwise provided by law, so long as any shares of the
Series B Preferred Stock shall remain outstanding, in the event of any
Reorganization (as defined in Section 11 below), other than a transaction for
the primary purpose of affecting a change in the state of incorporation of the
Corporation that does not result in any amendments, alteration, repeal or other
material and adverse change in the rights, preferences, privileges or
restrictions of the Series B Preferred Stock or in which the Corporation shall
be the surviving or acquiring corporation or the Parent party if the rights,
preferences, privileges or restrictions granted to or imposed upon the Series B
Preferred Stock remain unchanged unless an amendment is made to the
Corporation's Restated Articles of Incorporation which would otherwise require
such approval, the holders of Series B Preferred Stock, shall, except as
otherwise provided by law, be entitled to vote separately as a class with all
other preferred stock entitled to vote thereon with the shares of Series B
Preferred Stock on the subject matter to be approved under this Section 3(C).
Such approval shall be deemed to have been obtained upon receiving the
affirmative vote of a majority of the outstanding shares entitled to vote
thereon as a class.

         (D) (i) So long as any shares of Series B Preferred Stock remain
         outstanding, the Corporation shall not, without the consent or vote of
         the holders of at least a majority of the outstanding shares of the
         Series B Preferred Stock, voting separately as a class, in person or by
         proxy, consummate a transaction which would result in a Change in
         Control (as defined in Section 11 below) if the fair market value of
         Liquid Consideration (as defined in this paragraph (i) of this Section
         3(D)) payable or issuable upon the consummation of such transaction to
         the holders of Series B Preferred Stock (or, if greater, the fair
         market value of the Liquid Consideration payable or issuable upon the
         consummation of such transaction to the holder of the number of shares
         of Common Stock and/or any other securities that would be issuable to
         the holder of the Series B Preferred Stock if such holder converted the
         Series B Preferred Stock prior to the consummation of such transaction)
         is less than the Stated Value for each share of Series B Preferred
         Stock outstanding plus dividends accrued and unpaid for the then
         current Dividend Period (without accumulation of accrued and unpaid
         dividends for prior

                                       5



         Dividend Periods) to the date of consummation of such transaction.
         "Liquid Consideration" means (i) cash and/or (ii) securities which are
         part of a class (or, if designated in series, a series) of securities
         that has been for at least 90 days prior to, and will be immediately
         prior to the consummation of such transaction qualified for trading on
         the New York Stock Exchange, the Nasdaq National Market, any other
         national securities exchange or their respective successors, which
         securities will upon issuance, be likewise qualified, and subject to no
         limitations or restrictions other than restrictions arising from a
         holder's status as an affiliate or former affiliate of any of the
         parties to such transaction. The fair market value of the Liquid
         Consideration shall be determined as of the third Trading Day ending
         immediately prior to the consummation of such transaction. The fair
         market value of any securities shall be valued at the Current Market
         Price of such securities for the ten consecutive Trading Days ending on
         the third Trading Day immediately preceding consummation of such
         transaction.

         (ii) The Corporation shall give each holder of record of the
         outstanding Series B Preferred Stock written notice of any transaction
         that would result in a Change in Control at least 20 days prior to the
         stockholders' meeting called to approve the transaction that would
         result in the Change in Control, or at least 20 days prior to the
         consummation of such transaction, whichever is earlier. Such notice
         shall describe the material terms of the transaction and the provisions
         of this Section 3(D) and the Corporation shall thereafter give such
         holders prompt notice of any material changes. The transaction that
         would result in a Change in Control shall in no event be consummated
         sooner than 20 days after the Corporation has given the initial notice
         provided for in this paragraph (ii) of this Section 3(D) or sooner than
         10 days after the Corporation has given notice of any material changes
         as provided for herein; provided that such minimum periods may be
         shortened upon the written consent or approval of the holders of a
         majority of the outstanding Series B Preferred Stock.

         (E)  (i)      So long as any shares of the Series B Preferred Stock are
         outstanding, if full dividends on the shares of Series B Preferred
         Stock or on shares of Voting Parity Stock (as defined below in this
         paragraph (i) of this Section 3(E)), if any, or the equivalent thereof,
         shall fail to be declared and paid for any six consecutive Dividend
         Periods, then, subject to compliance with any requirement for
         regulatory approval of (or non-objection to) persons serving as
         directors, the holders of Series B Preferred Stock, voting together as
         a class with the holders of any other series of outstanding
         noncumulative preferred stock of the Corporation ranking on a parity
         with the Series B Preferred Stock as to dividends or upon liquidation,
         and upon which comparable voting rights as those of the Series B
         Preferred Stock have been conferred and made irrevocable ("Voting
         Parity Stock"), shall acquire the exclusive right to elect two
         directors at the Corporation's next annual meeting of shareholders or
         at a separate meeting called as described below in paragraph (iii) of
         this Section 3(E) or by written consent, and thereafter, at each
         subsequent annual meeting or by written consent, subject to the
         termination of such rights pursuant to paragraph (v) of this Section
         3(E).

              (ii)     In order to provide for the election of two directors, as
         required by the preceding paragraph in certain circumstances, the board
         of directors shall, promptly upon the occurrence of such circumstances,
         to the extent permitted by law and the Restated

                                       6



         Articles of Incorporation or bylaws of the Corporation, either increase
         the authorized number of directors by two or take such other action as
         necessary to permit the election of two representatives, including but
         not limited to, the calling of a special meeting of shareholders to
         effectuate a voting shift pursuant to Section 301(a) of the CGCL, by
         the Series B Preferred Stock and Voting Parity Stock, voting together
         as a class. To the extent the board of directors is not authorized to
         increase the number of directors of the Corporation at the time of the
         occurrence of the event specified in paragraph (i) of this Section
         3(E), but obtains such authorization on or prior to any meeting at
         which holders of the Series B Preferred Stock and Voting Parity Stock
         shall seek to elect directors pursuant to the preceding paragraph, then
         such an increase of the board of directors shall be effective for
         purposes of complying with the obligations of the Corporation in this
         paragraph.

              (iii)    Whenever the right to elect directors shall vest
         pursuant to this Section 3(E), such right may be exercised initially by
         the vote of the holders of a plurality of the shares of Series B
         Preferred Stock and Voting Parity Stock present and voting (separately
         as one class), in person or by proxy, at a duly held special meeting of
         holders of the Series B Preferred Stock and Voting Parity Stock or at
         the next annual meeting of shareholders, or by written consent without
         a meeting of the holders of record of a majority of the outstanding
         shares of Series B Preferred Stock and Voting Parity Stock voting
         separately as one class. Unless such action shall have been taken by
         written consent, a special meeting for the exercise of such right shall
         be called by the Secretary of the Corporation as promptly as possible,
         and in any event within ten days after receipt of a written request
         signed by the holders of record of at least 10% of the outstanding
         shares of the Series B Preferred Stock or Voting Parity Stock, subject
         to any applicable notice requirements imposed by law or regulation.
         Notwithstanding the provisions of this paragraph (iii) of this Section
         3(E), no such special meeting shall be required to be held during the
         90-day period preceding the date fixed for the annual meeting of
         shareholders.

              (iv)     If any meeting of the holders of the Series B Preferred
         Stock and Voting Parity Stock required under this Section 3(E) to be
         called shall not have been called within 30 days after personal service
         of a written request therefor upon the Secretary of the Corporation or
         within 30 days after mailing the same within the United States of
         America by registered mail addressed to the Secretary of the
         Corporation at its principal executive offices, subject to any
         applicable notice requirements imposed by law or regulation, then the
         holders of record of at least 10% of the outstanding shares of the
         Series B Preferred Stock or Voting Parity Stock may designate in
         writing one of their number to call such meeting at the expense of the
         Corporation, and such meeting may be called by such person so
         designated upon the notice required for annual meetings of shareholders
         or such shorter notice (but in no event shorter than permitted by law
         or regulation) as may be acceptable to the holders of a majority of the
         total number of shares of the Series B Preferred Stock and Voting
         Parity Stock, voting as a class. In addition to all rights provided by
         law, any holder of Series B Preferred Stock so designated shall have
         access to the Series B Preferred Stock and Voting Parity Stock books of
         the Corporation for the purpose of causing such meeting to be called
         pursuant to these provisions.

                                       7



              (v)      Such right of the holders of the Series B Preferred Stock
         and Voting Parity Stock entitled to vote in accordance with this
         Section 3(E) shall continue until, following the event which gave rise
         to such right, the Corporation shall have resumed the payment of full
         dividends upon the Series B Preferred Stock for the equivalent of four
         consecutive quarterly Dividend Periods, at which time such right shall
         terminate, except as by law expressly provided, subject to revesting in
         the event the conditions set forth in paragraph (i) of this Section
         3(E) are again triggered. Upon any such termination, the term of office
         of each director then in office elected by such holders voting as a
         class (hereinafter, "Preferred Director") shall immediately terminate,
         unless otherwise required by law. Any Preferred Director may be removed
         by, and shall not be removed except by, the vote of the holders of
         record of the outstanding shares of Series B Preferred Stock and Voting
         Parity Stock, voting together as a single class, at a meeting of the
         Corporation's shareholders, or of the holders of shares of Series B
         Preferred Stock and Voting Parity Stock, called for such purpose. So
         long as a default in any preference dividends on the Series A Preferred
         Stock and Voting Parity Stock shall exist, (1) any vacancy in the
         office of a Preferred Director may be filled by a person appointed by
         an instrument in writing signed by the remaining Preferred Director,
         unless there is no remaining Preferred Director, and filed with the
         Corporation and (2) in the case of the removal of any Preferred
         Director, or in the case that there is no remaining Preferred Director,
         the vacancy or vacancies may be filled by a person elected by the vote
         of the holders of the outstanding shares of Series B Preferred Stock
         and Voting Parity Stock, voting together as a single class without
         regard to series, at the same meeting at which such removal shall be
         voted or at any subsequent meeting. Each director appointed as
         aforesaid by the remaining Preferred Director shall be deemed, for all
         purposes hereof, to be a Preferred Director. Any vacancy in the office
         of a Preferred Director shall be filled only as set forth in this
         Section 3(E)(v).

              (vi)     At any meeting of the holders of the Series B Preferred
         Stock and Voting Parity Stock called in accordance with the provisions
         of this Section 3(E), for the election or removal of directors, the
         presence in person or by proxy of the holders of a majority of the
         total number of shares of the Series B Preferred Stock and Voting
         Parity Stock shall be required to constitute a quorum; in the absence
         of a quorum, a majority of the holders present in person or by proxy
         shall have power to adjourn the meeting from time to time without
         notice other than an announcement at the meeting, until a quorum shall
         be present.

         (F) In connection with any matter on which holders of the Series B
Preferred Stock and Voting Parity Stock are entitled to vote as provided in
Sections 3(B), 3(C), 3(D) and 3(E) above, or any matter on which the holders of
the Series B Preferred Stock are entitled to vote as one class or otherwise
pursuant to law or the provisions of the Restated Articles of Incorporation,
each holder of Series B Preferred Stock shall be entitled, except as otherwise
required by law, to one vote for each share of Series B Preferred Stock held by
such holder.

                                       8



         Section 4.    Redemption.
                       ----------

         (A)  Except upon the occurrence of a Change in Control Event (as
defined in Section 11 below), the shares of Series B Preferred Stock shall not
be redeemable prior to the fifth anniversary of the Issue Date. At any time
following the earlier to occur of a Change in Control Event or the fifth
anniversary of the Issue Date, the shares of Series B Preferred Stock may be
redeemed, at the option of the Corporation, as a whole or from time to time in
part, subject to the receipt of any required prior approval of the Board of
Governors of the Federal Reserve System and any restrictions or conditions which
may be contained in the Restated Articles of Incorporation or in any other
certificates of determination designating the rights, preferences, privileges
and restrictions of any other series of preferred stock, at a redemption price
in the amount of the Stated Value per share thereof plus, in each case,
dividends for the current Dividend Period ( without accumulation of accrued and
unpaid dividends for prior Dividend Periods), without interest thereon (the
"Redemption Price") to the date fixed for such redemption. If fewer than all of
the outstanding shares of Series B Preferred Stock are to be redeemed, the
number of shares to be redeemed shall be determined by the board of directors,
and such shares shall be redeemed either pro rata or by lot, or by any other
method at the discretion of the board of directors. Regardless of the method
used, the calculation of the number of shares to be redeemed shall be based upon
whole shares, such that the Corporation shall in no event be required to issue
fractional shares of Series B Preferred Stock or cash in lieu thereof. In the
event a method requiring proration is used, shares shall be rounded downward to
the nearest total number of shares.

         (B)  If the Corporation shall redeem shares of Series B Preferred Stock
pursuant to Section 4(A), notice of such redemption shall be mailed by first
class mail, postage prepaid, to each holder of the shares to be redeemed, at
such holder's address as the same appears on the stock books of the Corporation.
Such notice shall be mailed not less than 20 nor more than 60 days prior to the
date fixed for redemption and shall set forth: (i) the redemption date, (ii) the
number of shares of Series B Preferred Stock that are to be redeemed, (iii) the
Redemption Price (specifying the amount of accrued and unpaid dividends to be
included therein), (iv) the place or places where certificates for such shares
of Series B Preferred Stock are to be surrendered for payment of the Redemption
Price and (v) that dividends on the shares to be redeemed will cease to accrue
on such redemption date. If fewer than all shares held by any holder are to be
redeemed, the notice mailed to such holder shall also specify the number of
shares to be redeemed from such holder.

         (C)  On the date of any redemption being made pursuant to Section 4(A)
which is specified in a notice given pursuant to Section 4(B), the Corporation
shall, and at any time after such notice shall have been mailed and before the
date of redemption the Corporation may, deposit for the benefit of the holders
of shares of Series B Preferred Stock to be redeemed the funds necessary for
such redemption, including the amount necessary to pay all accrued and unpaid
dividends to the date of redemption, with a bank or trust company in the
Counties of Santa Clara or San Francisco having a capital and surplus of at
least $50,000,000. Any moneys so deposited by the Corporation and unclaimed at
the end of six months from the date designated for such redemption shall revert
to the general funds of the Corporation. After such reversion, any such bank or
trust company shall, upon demand, pay over to the Corporation such unclaimed
amounts and thereupon such bank or trust company shall be relieved of all
responsibility in

                                       9



respect thereof and any holder of shares of Series B Preferred Stock to be
redeemed shall look only to the Corporation for the payment of the Redemption
Price. In the event that moneys are deposited pursuant to this Section 4(C) in
respect of shares of Series B Preferred Stock that are converted in accordance
with the provisions of Section 6, such moneys shall, upon such conversion,
revert to the general funds of the Corporation and, upon demand, such bank or
trust company shall pay over to the Corporation such moneys and shall be
relieved of all responsibility to the holders of such converted shares in
respect thereof. Any interest accrued on funds deposited pursuant to this
Section 4(C) shall be paid from time to time to the Corporation for its own
account.

         (D)  Notice of redemption having been given as aforesaid, upon the
deposit of funds pursuant to Section 4(C) in respect of shares of Series B
Preferred Stock to be redeemed pursuant to Section 4(A), notwithstanding that
any certificates for such shares shall not have been surrendered for
cancellation, from and after the date of redemption designated in the notice of
redemption (i) the shares represented thereby shall no longer be deemed
outstanding, (ii) the rights to receive dividends thereon shall cease to accrue,
and (iii) all rights of the holders of shares of Series B Preferred Stock to be
redeemed shall cease and terminate, excepting only the right to receive the
Redemption Price therefor, and the right to convert such shares into shares of
Common Stock until the close of business on the Business Day next preceding the
date of redemption, in accordance with Section 6 hereof.

         Section 5. Liquidation Rights. In the event of any voluntary or
                    ------------------
involuntary liquidation, dissolution or winding up of the Corporation, the
holders of Series B Preferred Stock will be entitled to receive out of the
assets of the Corporation available for distribution to Corporation
shareholders, before any distribution of assets is made to the holders of the
Common Stock or any other equity security ranking junior to the Series B
Preferred Stock as to distributions on liquidation, dissolution and winding up,
liquidating distributions in the amount of the Stated Value for each share
outstanding plus dividends accrued and unpaid for the then-current Dividend
Period (without accumulation of accrued and unpaid dividends for prior Dividend
Periods) to the date fixed for such liquidation, dissolution or winding up. All
payments for which these liquidation rights are provided shall be in cash. If,
upon any voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, the amounts payable with respect to the Series B Preferred Stock or
any equity security of the Corporation ranking equally with the Series B
Preferred Stock as to distributions upon liquidation, dissolution or winding up
are not paid in full, the holders of the Series B Preferred Stock and any
preferred stock ranking equally with the Series B Preferred Stock as to
distributions upon liquidation, dissolution or winding up will share ratably in
any such distribution of the assets of the Corporation in proportion to the full
respective preferential amounts to which they are entitled. After payment of the
full amount of the liquidating distribution to which they are entitled, the
holders of Series B Preferred Stock will not be entitled to any further
participation in any distribution of assets of the Corporation. All
distributions made with respect to the Series B Preferred Stock in connection
with such liquidation, dissolution or winding up of the Corporation shall be
made pro rata to the holders entitled thereto. For purposes of this Section 5,
neither the voluntary sale, conveyance, exchange or transfer of all or
substantially all of the property or assets of the Corporation nor the
consolidation or merger of the Corporation with or into any other entity shall
be deemed to be a voluntary or involuntary liquidation, dissolution or winding
up of the Corporation.

                                       10



     Section 6. Conversion Rights.
                -----------------

     (A) Subject to the provisions for adjustment hereinafter set forth, each
share of Series B Preferred Stock shall be convertible at the option of the
holder thereof into fully paid and nonassessable shares of Common Stock. The
number of shares of Common Stock deliverable upon conversion of a share of
Series B Preferred Stock, adjusted as hereinafter provided, is referred to
herein as the "Conversion Ratio." The Conversion Ratio (as defined in Section 11
below) shall initially be 1.67 and the conversion price shall initially be
$30.00 (the initial conversion price and as subsequently adjusted is referred to
herein as the "Conversion Price.") The Conversion Ratio and the Conversion Price
are subject to adjustment from time to time pursuant to Section 6(F).

     (B) Conversion of the Series B Preferred Stock may be effected by any such
holder upon the surrender to the Corporation at the principal office of the
Corporation in the State of California or at the office of any agent or agents
of the Corporation (the "Transfer Agent"), as may be designated by the board of
directors of the Corporation, of the certificate for such Series B Preferred
Stock to be converted accompanied by a written notice stating that such holder
elects to convert all or a specified whole number of such shares in accordance
with the provisions of this Section 6 and specifying the name or names in which
such holder wishes the certificate or certificates for shares of Common Stock to
be issued. In case such notice shall specify a name or names other than that of
such holder, such notice shall be accompanied by payment of all transfer taxes
payable upon the issuance of shares of Common Stock in such name or names. Other
than such taxes, the Corporation will pay any and all issue and other taxes
(other than taxes based on income) that may be payable in respect of any issue
or delivery of shares of Common Stock on conversion of Series B Preferred Stock
pursuant hereto. As promptly as practicable, and in any event within five
Business Days after the surrender of such certificate or certificates and the
receipt of such notice relating thereto and, if applicable, payment of all
transfer taxes (or the demonstration to the satisfaction of the Corporation that
such taxes have been paid), the Corporation shall deliver or cause to be
delivered (i) certificates representing the number of validly issued, fully paid
and nonassessable full shares of Common Stock to which the holder of shares of
Series B Preferred Stock being converted shall be entitled and (ii) if less than
the full number of shares of Series B Preferred Stock evidenced by the
surrendered certificate or certificates is being converted, a new certificate or
certificates, of like tenor, for the number of shares evidenced by such
surrendered certificate or certificates less the number of shares being
converted. Such conversion shall be deemed to have been made at the close of
business on the date of giving such notice and of such surrender of the
certificate or certificates representing the shares of Series B Preferred Stock
to be converted so that the rights of the holder thereof as to the shares being
converted shall cease except for the right to receive shares of Common Stock in
accordance herewith, and the person entitled to receive the shares of Common
Stock shall be treated for all purposes as having become the record holder of
such shares of Common Stock at such time. The Corporation shall not be required
to convert, and no surrender of shares of Series B Preferred Stock shall be
effective for that purpose, while the transfer books of the Corporation for the
Common Stock are closed for any purpose (but not for any period in excess of
five days); but the surrender of shares of Series B Preferred Stock for
conversion during any period while such books are so closed shall become
effective for conversion immediately upon the reopening of such books, as if the
conversion had been made

                                       11



on the date such shares of Series B Preferred Stock were surrendered, and at the
Conversion Ratio in effect at the date of such surrender.

     (C)  In case any shares of Series B Preferred Stock are to be redeemed
pursuant to Section 4, such right of conversion shall cease and terminate as to
the shares of Series B Preferred Stock to be redeemed at the close of business
on the Business Day next preceding the date fixed for redemption unless the
Corporation shall default in the payment of the Redemption Price.

     (D)  Upon conversion, the holder of shares of Series B Preferred Stock
surrendered for conversion after the Record Date next preceding a Series B
Dividend Payment Date for the Series B Preferred Stock, if such dividend has
been declared and such Record Date has been established by the board of
directors, and prior to such Series B Dividend Payment Date shall be entitled to
receive an amount equal to the declared, accrued and unpaid dividend for such
current Dividend Period prorated from the first day of such current Dividend
Period to the date of conversion computed on the basis of a 360-day year
consisting of twelve 30-day months.

     (E)  No fractional share of Common Stock shall be issued upon conversion of
shares of Series B Preferred Stock, but, instead of any fraction which would
otherwise be issuable in respect of the aggregate number of shares of Series B
Preferred Stock surrendered for conversion at one time by the same holder, the
Corporation shall pay a cash adjustment in an amount equal to the same fraction
of the Current Market Price (as defined in Section 11 below) per share of the
Common Stock on the date on which the certificate or certificates for such
shares were duly surrendered for conversion, or, if such date is not a Trading
Day (as defined in Section 11 below), on the next Trading Day.

     (F)  The Conversion Price and Conversion Ratio shall be adjusted from time
to time as follows:

          (i) In the event the Corporation shall at any time after the Issue
     Date (A) declare a dividend on the Common Stock payable in shares of its
     capital stock, (B) subdivide its outstanding Common Stock, (C) combine its
     outstanding Common Stock or (D) issue pursuant to a reclassification of its
     outstanding Common Stock any shares of capital stock of the Corporation,
     the holder of any shares of Series B Preferred Stock surrendered for
     conversion after the record date for such dividend or distribution (which
     for this purpose shall be at the close of business on the date fixed by the
     board of directors as the record date), or after the close of business on
     the effective date of such subdivision, combination or reclassification, as
     the case may be (the close of business times being hereinafter referred to
     in this paragraph (i) as "such record date") shall be entitled to receive
     the aggregate number and kind of shares of capital stock of the Corporation
     which, if such shares of Series B Preferred Stock had been converted
     immediately prior to such record date at the Conversion Price and
     Conversion Ratio then in effect, he would have been entitled to receive by
     virtue of such dividend, distribution, subdivision, combination or
     reclassification; and the Conversion Price and Conversion Ratio shall be
     deemed to have been adjusted after such record date to apply to such
     aggregate number and kind of shares. If any dividend, distribution,
     subdivision, combination or reclassification is not paid or made, the
     Conversion Price and Conversion

                                       12



     Ratio then in effect shall be appropriately readjusted. Such adjustment or
     readjustments shall be made whenever any of the events listed above shall
     occur.

          (ii)  In case the Corporation shall fix after the Issue Date a record
     date for issuing to all holders of shares of Common Stock rights or
     warrants entitling them to purchase or subscribe for shares of Common Stock
     (or securities convertible into Common Stock) at a price per share of
     Common Stock (or having a conversion price per share of Common Stock, if a
     security convertible into Common Stock) less than the Current Market Price
     per share of the Common Stock on such record date, the Conversion Price in
     effect from and after such record date shall be adjusted so that it shall
     be equal to the price determined by multiplying the Conversion Price in
     effect immediately prior to the record date by a fraction, of which the
     numerator shall be the number of shares of Common Stock outstanding on such
     record date plus the number of shares of Common Stock which the aggregate
     offering price of the total number of shares of Common Stock so offered (or
     the aggregate initial conversion price of the convertible securities so
     offered) for subscription or purchase would purchase at such Current Market
     Price at such record date, and of which the denominator shall be the number
     of shares of Common Stock outstanding on such record date plus the number
     of shares of additional Common Stock so offered for subscription or
     purchase (or into which the convertible securities so offered are initially
     convertible). Such adjustment shall be made successively whenever such a
     record date is fixed. If any or all of such rights or warrants are not
     issued or any or all of such rights, warrants or conversion privileges
     expire or terminate without having been exercised, the Conversion Price
     shall be appropriately readjusted retroactively on the basis that the only
     shares of Common Stock so issued were the shares of Common Stock, if any,
     actually issued upon exercise of such rights, warrants or conversion
     privileges.

          (iii) In case the Corporation shall fix a record date after the Issue
     Date for the distribution to all holders of shares of Common Stock of
     evidence of its indebtedness or assets (excluding cash dividends if the
     amount to be paid, together with the amount of cash dividends on the Common
     Stock paid since the fourth previous Dividend Payment Date, does not exceed
     the Corporation's net earnings for the four quarterly fiscal periods most
     recently ended prior to the record date for such cash dividend) or rights
     or warrants to subscribe or purchase any of its securities (excluding those
     referred to in paragraph (ii) of this Section 6(F)), then in each such case
     the Conversion Price in effect from and after such record date shall be
     adjusted so that the same shall be equal to the price determined by
     multiplying the Conversion Price in effect immediately prior to such record
     date by a fraction, of which the numerator shall be the Current Market
     Price per share of the Common Stock on such record date less the fair
     market value (as determined by a resolution of the board of directors filed
     with each Transfer Agent for the Series B Preferred Stock, which
     determination, if made in good faith, shall be conclusive) of the portion
     of the evidences of indebtedness or assets so distributed or of such rights
     to subscribe applicable to a share of Common Stock, and of which the
     denominator shall be such Current Market Price on such record date. Such
     adjustment shall be made whenever any such a record date is fixed. If any
     such distribution is not made or any or all of such rights, warrants or
     conversion privileges expire or terminate without having been exercised,
     the Conversion Price shall be appropriately readjusted retroactively.

                                       13



          (iv)   In any case in which this Section 6(F) shall require that an
     adjustment as a result of any event become effective from and after a
     record date, the Corporation may elect to defer until after the occurrence
     of such event (1) issuing to the holder of any shares of Series B Preferred
     Stock converted after such record date and before the occurrence of such
     event the additional Common Stock issuable upon such conversion over and
     above the shares issuable on the basis of the Conversion Price in effect
     immediately prior to adjustment and (2) paying to such holder any amount in
     cash in lieu of a fractional Common Stock pursuant to Section 6(E) above.
     In lieu of the shares the issuance of which is deferred pursuant to clause
     (1) above, the Corporation shall issue or cause its transfer agent to issue
     due bills or other appropriate evidence of the right to receive such
     shares.

          (v)    Any adjustment in the Conversion Price and Conversion Ratio
     otherwise required by this Section 6 to be made may be postponed, if such
     adjustment (plus any other adjustments postponed pursuant to this paragraph
     (v) of this Section 6(F) and not theretofore made) would not require an
     increase or decrease of more than 1% in such price. All calculations under
     this Section 6(F) shall be made to the nearest cent or to the nearest 1/100
     of a share, as the case may be.

          (vi)   The board of directors may make such adjustments in the
     Conversion Price and Conversion Ratio, in addition to those required by
     this Section 6(F), as shall be determined by the board of directors, as
     evidenced by a resolution of the board of directors, to be advisable in
     order to avoid taxation so far as practicable of any dividend of stock or
     stock rights or any event treated as such for Federal income tax purposes
     to the recipients.

          (vii)  In the event that at any time, as a result of an adjustment
     made pursuant to paragraph (i) of this Section 6(F), the holder of any
     shares of Series B Preferred Stock thereafter surrendered for conversion
     shall become entitled to receive any shares of capital stock of the
     Corporation other than Common Stock, thereafter the number of such other
     shares so receivable upon conversion of such shares of Series B Preferred
     Stock shall be subject to adjustment from time to time in a manner and on
     terms as nearly equivalent as practicable to the provisions with respect to
     the Common Stock contained in paragraphs (i) to (vi), inclusive, of this
     Section 6(F), and the other provisions of this Section 6(F) with respect to
     the Common Stock shall apply on like terms to any such other shares.

          (viii) Notwithstanding the foregoing, in no event shall any
     adjustments to the Conversion Price or Conversion Ratio be made pursuant to
     this Section 6(F) in connection with the Corporation's shareholder rights
     plan, as adopted on November 17, 1998, or any amendment thereto, or any
     successor shareholder rights plan established by the Corporation for the
     benefit of the Corporation's holders of Common Stock.

     (G)  Whenever the Conversion Price and Conversion Ratio are adjusted as
herein provided:

                                       14



          (i)   The Corporation shall compute the adjusted Conversion Price and
     Conversion Ratio and shall cause to be prepared a certificate signed by the
     Corporation's chief financial officer setting forth the adjusted Conversion
     Price and Conversion Ratio and a brief statement of the facts requiring
     such adjustment and the computation thereof; such certificate shall
     forthwith be filed with its Transfer Agent for the Series B Preferred
     Stock; and

          (ii)  A notice stating that the Conversion Price and Conversion Ratio
     has been adjusted and setting forth the adjusted Conversion Price and
     Conversion Ratio shall, as soon as practicable, be mailed to the holders of
     record of outstanding shares of the Series B Preferred Stock.

     (H)  In case:

          (i)   The Corporation shall declare a dividend or other distribution
     on its Common Stock, other than in cash;

          (ii)  The Corporation shall authorize the issuance to all holders of
     its Common Stock of rights or warrants entitling them to subscribe for or
     purchase any Common Stock or any other subscription rights or warrants;

          (iii) Of any reclassification of the capital stock of the Corporation
     (other than a subdivision or combination of its outstanding Common Stock),
     or of any consolidation or merger to which the Corporation is a party and
     for which approval of any shareholders of the Corporation is required, or
     of the sale, lease, exchange or other disposition of all or substantially
     all the property and assets of the Corporation; or

          (iv)  Of the voluntary or involuntary liquidation, dissolution or
     winding up of the Corporation;

then the Corporation shall cause to be mailed to the Transfer Agent for the
Series B Preferred Stock and to the holders of record of the outstanding shares
of Series B Preferred Stock, at least 20 days (or 10 days in any case specified
in paragraphs (i) or (ii) above) prior to the applicable record or effective
date hereinafter specified, a notice stating (x) the date as of which the
holders of record of Common Stock to be entitled to such dividend, distribution,
rights or warrants are to be determined, or (y) the date on which such
reclassification, consolidation, subdivision merger, sale, lease, exchange,
disposition, liquidation, dissolution or winding up is expected to become
effective, and the date as of which it is expected that holders of record of
Common Stock shall be entitled to exchange their shares for securities or other
property, if any, deliverable upon such reclassification, consolidation, merger,
sale, lease, exchange, disposition, liquidation, dissolution or winding up. The
failure to give the notice required by this Section 6(H), or any defect therein,
shall not affect the legality or validity of any such dividend, distribution,
right, warrant, reclassification, consolidation, merger, sale, lease, exchange,
disposition, liquidation, dissolution or winding up, or the vote on any action
authorizing such.

     (I)  In case of any capital reorganization or reclassification of
outstanding shares of Common Stock, or in case of any merger or consolidation of
the Corporation with or into another corporation, pursuant to which the
outstanding shares of Common Stock are by operation of law

                                       15



exchanged for, changed, converted or reclassified (other than a reclassification
covered by paragraph (i) of Section 6(F) into stock, securities, other property
(including cash) or a combination thereof ("Consideration") (each of the
foregoing being referred to as a "Transaction"), each share of Series B
Preferred Stock shall thereafter be convertible into, in lieu of the Common
Stock issuable upon such conversion prior to consummation of such Transaction,
the Consideration so receivable upon the consummation of such Transaction by a
holder of that number of shares of Common Stock into which one share of Series B
Preferred Stock was convertible immediately prior to such Transaction.

         (J) The Corporation shall at all times reserve and keep available, free
from preemptive rights, out of its authorized but unissued Common Stock for the
purpose of issuance upon conversion of the Series B Preferred Stock, the full
number of shares of Common Stock then deliverable upon the conversion of all
shares of Series B Preferred Stock then outstanding.

         (K) The certificate of any independent firm of public accountants of
recognized standing selected by the board of directors shall be presumptive
evidence of the correctness of any computation made under this Section 6.

         Section 7.    No Sinking Fund. No sinking fund will be established for
                       ---------------
the retirement or redemption of shares of Series B Preferred Stock, unless
otherwise specifically provided herein.

         Section 8.    Preemptive Rights. No holder of shares of the Series B
                       -----------------
Preferred Stock shall have any preemptive right to subscribe to stock,
obligations, warrants, rights to subscribe to stock, or other securities of the
Corporation of any class, whether now or hereafter authorized.

         Section 9.    Reacquired Shares. Any shares of the Series B Preferred
                       -----------------
Stock which are redeemed, purchased or otherwise acquired by the Corporation in
any manner whatsoever shall be retired and canceled promptly after the
acquisition thereof. All such shares upon their cancellation shall become
authorized but unissued shares of Preferred Stock without designation as to
series and may thereafter be reissued as part of a new series of preferred stock
to be created by resolution of the board of directors.

         Section 10.   No Other Rights. The shares of Series B Preferred Stock
                       ---------------
shall not have any preferences, voting powers or relative, participating,
optional or other special rights except as set forth above and in the Restated
