Attention: Kamran Husain

Dear Mr. Husain:


         This letter amendment (this "Amendment") is to confirm the changes
agreed upon between Wells Fargo Bank, National Association ("Bank") and Greater
Bay Bancorp ("Borrower") to the terms and conditions of that certain letter
agreement between Bank and Borrower dated as of November 4, 1999, as amended
from time to time (the "Agreement"). For valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Bank and Borrower hereby agree
that the Agreement shall be amended as follows to reflect said changes.

         1. The Agreement is hereby amended (a) by deleting "October 30, 2001"
as the last day on which Bank will make advances under the Line of Credit, and
by substituting for said date "January 31, 2002," with such change to be
effective upon the execution and delivery to Bank of a promissory note
substantially in the form of Exhibit A attached hereto (which promissory note
shall replace and be deemed the Line of Credit Note defined in and made pursuant
to the Agreement) and all other contracts, instruments and documents required by
Bank to evidence such change. In no event shall proceeds of the Line of Credit
be used to finance acquisitions.

         2. In consideration of the changes set forth herein and as a condition
to the effectiveness hereof, immediately upon signing this Amendment Borrower
shall pay to Bank a non-refundable fee of $10,000.00.

         3. Except as specifically provided herein, all terms and conditions of
the Agreement remain in full force and effect, without waiver or modification.
All terms defined in the Agreement shall have the same meaning when used herein.
This Amendment and the Agreement shall be read together, as one document.

         4. Borrower hereby remakes all representations and warranties contained
in the Agreement and reaffirms all covenants set forth therein. Borrower further
certifies that as of the date of Borrower's acknowledgment set forth below there
exists no default or defined event of default under the Agreement or any
promissory note or other contract, instrument or document executed in connection
therewith, nor any condition, act or event which with the giving of notice or
the passage of time or both would constitute such a default or defined event of
default.

         5. The effective date of this Amendment shall be October 31, 2001.

                          REVOLVING LINE OF CREDIT NOTE


$40,000,000.00                                         San Francisco, California
                                                            October 31, 2001

         FOR VALUE RECEIVED, the undersigned GREATER BAY BANCORP ("Borrower")
promises to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION ("Bank")
at its office at 420 Montgomery, San Francisco, California, or at such other
place as the holder hereof may designate, in lawful money of the United States
of America and in immediately available funds, the principal sum of Forty
Million Dollars ($40,000,000.00), or so much thereof as may be advanced and be
outstanding, with interest thereon, to be computed on each advance from the date
of its disbursement as set forth herein.

DEFINITIONS:

         As used herein, the following terms shall have the meanings set forth
after each, and any other term defined in this Note shall have the meaning set
forth at the place defined:

         (a) "Business Day" means any day except a Saturday, Sunday or any other
day on which commercial banks in California are authorized or required by law to
close.

         (b) "Fixed Rate Term" means, for each LIBOR-based advance requested
hereunder, a period commencing on a Business Day designated by Borrower and
continuing for three (3) months, during which the outstanding principal amount
under this Note related to such advance bears interest determined in relation to
LIBOR as in effect on the first Business Day of the applicable 3 month period;
provided however, that no Fixed Rate Term shall extend beyond the scheduled
maturity date hereof. If any Fixed Rate Term would end on a day that is not a
Business Day, then such Fixed Rate Term shall be extended to the next succeeding
Business Day.

         (c) "LIBOR" means the rate per annum (rounded upward, if necessary, to
the nearest whole 1/8 of 1%) and determined pursuant to the following formula:

         LIBOR =             Base LIBOR
                  -------------------------------
                  100% - LIBOR Reserve Percentage

"Base LIBOR" means the rate per annum for United States dollar deposits quoted
by Bank as the Inter-Bank Market Offered Rate, with the understanding that such
rate is quoted by Bank for the purpose of calculating effective rates of
interest for loans making reference thereto, on the first day of a Fixed Rate
Term for delivery of funds on said date for a period of time approximately equal
to the number of days in such Fixed Rate Term and in an amount approximately
equal to the principal amount to which such Fixed Rate Term applies. Borrower
understands and agrees that Bank may base its quotation of the Inter-Bank Market
Offered Rate upon such offers or other market indicators of the Inter-Bank
Market as Bank in its discretion deems appropriate including, but not limited
to, the rate offered for U.S. dollar deposits on the London Inter-Bank Market.

    (ii) "LIBOR Reserve Percentage" means the reserve percentage prescribed by
the Board of Governors of the Federal Reserve System (or any successor) for
"Eurocurrency Liabilities" (as defined in Regulation D of the Federal Reserve
Board, as amended), adjusted by Bank for expected changes in such reserve
percentage during the applicable Fixed Rate Term.



         (d) "Prime Rate" means at any time the rate of interest most recently
announced within Bank at its principal office as its Prime Rate, with the
understanding that the Prime Rate is one of Bank's base rates and serves as the
basis upon which effective rates of interest are calculated for those loans
making reference thereto, and is evidenced by the recording thereof after its
announcement in such internal publication or publications as Bank may designate.

INTEREST:

         (a) Interest. The outstanding principal balance of this Note shall bear
             --------
interest (computed on the basis of a 360-day year, actual days elapsed) either
(i) at a fluctuating rate per annum two and one quarter percent (2.25%) below
the Prime Rate in effect from time to time, or (ii) at a fixed rate per annum
determined by Bank to be two fifths percent (0.40%) above LIBOR in effect on the
first day of the applicable Fixed Rate Term. When interest is determined in
relation to the Prime Rate, each change in the rate of interest hereunder shall
become effective on the date each Prime Rate change is announced within Bank.
With respect to each LIBOR selection hereunder, Bank is hereby authorized to
note the date, principal amount, interest rate and Fixed Rate Term applicable
thereto and any payments made thereon on Bank's books and records (either
manually or by electronic entry) and/or on any schedule attached to this Note,
which notations shall be prima facie evidence of the accuracy of the information
noted.

         (b) Selection of Interest Rate Options. At any time any portion of this
             ----------------------------------
Note bears interest determined in relation to LIBOR, it may be continued by
Borrower at the end of the Fixed Rate Term applicable thereto so that all or a
portion thereof bears interest determined in relation to the Prime Rate or to
LIBOR for a new Fixed Rate Term designated by Borrower. At any time any portion
of this Note bears interest determined in relation to the Prime Rate, Borrower
may convert all or a portion thereof so that it bears interest determined in
relation to LIBOR for a Fixed Rate Term designated by Borrower. At such time as
Borrower requests an advance hereunder or wishes to select a LIBOR option for
all or a portion of the outstanding principal balance hereof, and at the end of
each Fixed Rate Term, Borrower shall give Bank notice specifying: (i) the
interest rate option selected by Borrower; (ii) the principal amount subject
thereto; and (iii) for each LIBOR selection, the length of the applicable Fixed
Rate Term. Any such notice may be given by telephone (or such other electronic
method as Bank may permit) so long as, with respect to each LIBOR selection, (A)
if requested by Bank, Borrower provides to Bank written confirmation thereof not
later than three (3) Business Days after such notice is given, and (B) such
notice is given to Bank prior to 10:00 a.m. on the first day of the Fixed Rate
Term, or at a later time during any Business Day if Bank, at it's sole option
but without obligation to do so, accepts Borrower's notice and quotes a fixed
rate to Borrower. If Borrower does not immediately accept a fixed rate when
quoted by Bank, the quoted rate shall expire and any subsequent LIBOR request
from Borrower shall be subject to a redetermination by Bank of the applicable
fixed rate. If no specific designation of interest is made at the time any
advance is requested hereunder or at the end of any Fixed Rate Term, Borrower
shall be deemed to have made a Prime Rate interest selection for such advance or
the principal amount to which such Fixed Rate Term applied.

         (c) Taxes and Regulatory Costs. Borrower shall pay to Bank immediately
             --------------------------
upon demand, in addition to any other amounts due or to become due hereunder,
any and all (i) withholdings, interest equalization taxes, stamp taxes or other
taxes (except income and franchise taxes) imposed by any domestic or foreign
governmental authority and related in any manner to LIBOR, and (ii) future,
supplemental, emergency or other changes in the LIBOR Reserve Percentage,
assessment rates imposed by the Federal Deposit Insurance Corporation, or
similar requirements or costs imposed by any domestic or foreign governmental
authority or



resulting from compliance by Bank with any request or directive (whether or not
having the force of law) from any central bank or other governmental authority
and related in any manner to LIBOR to the extent they are not included in the
calculation of LIBOR. In determining which of the foregoing are attributable to
any LIBOR option available to Borrower hereunder, any reasonable allocation made
by Bank among its operations shall be conclusive and binding upon Borrower.

         (d) Payment of Interest. Interest accrued on this Note shall be payable
             -------------------
on the last day of each month, commencing November 30, 2001 and on the maturity
date of this Note.

         (e) Default Interest. From and after the maturity date of this Note, or
             ----------------
such earlier date as all principal owing hereunder becomes due and payable by
acceleration or otherwise, the outstanding principal balance of this Note shall
bear interest until paid in full at an increased rate per annum (computed on the
basis of a 360-day year, actual days elapsed) equal to four percent (4%) above
the rate of interest from time to time applicable to this Note.

BORROWING AND REPAYMENT:

         (a) Borrowing and Repayment. Borrower may from time to time during the
             -----------------------
term of this Note borrow, partially or wholly repay its outstanding borrowings,
and reborrow, subject to all of the limitations, terms and conditions of this
Note and of any document executed in connection with or governing this Note;
provided however, that the total outstanding borrowings under this Note shall
not at any time exceed the principal amount stated above. The unpaid principal
balance of this obligation at any time shall be the total amounts advanced
hereunder by the holder hereof less the amount of principal payments made hereon
by or for Borrower, which balance may be endorsed hereon from time to time by
the holder. The outstanding principal balance of this Note shall be due and
payable in full on January 31, 2002.

         (b) Advances. Advances hereunder, to the total amount of the principal
             --------
sum stated above, may be made by the holder at the oral or written request of
(i) Kamran Husain, Steven Smith, Shawn Saunders or Mark Eschen, any one acting
alone, who are authorized to request advances and direct the disposition of any
advances until written notice of the revocation of such authority is received by
the holder at the office designated above, or (ii) any person, with respect to
advances deposited to the credit of any account of Borrower with the holder,
which advances, when so deposited, shall be conclusively presumed to have been
made to or for the benefit of Borrower regardless of the fact that persons other
than those authorized to request advances may have authority to draw against
such account. The holder shall have no obligation to determine whether any
person requesting an advance is or has been authorized by Borrower.

         (c) Application of Payments. Each payment made on this Note shall be
             -----------------------
credited first, to any interest then due and second, to the outstanding
principal balance hereof. All payments credited to principal shall be applied
first, to the outstanding principal balance of this Note which bears interest
determined in relation to the Prime Rate, if any, and second, to the outstanding
principal balance of this Note which bears interest determined in relation to
LIBOR, with such payments applied to the oldest Fixed Rate Term first.

PREPAYMENT:

         (a) Prime Rate.  Borrower may prepay principal on any portion of this
             ----------
Note which bears interest determined in relation to the Prime Rate at any time,
in any amount and without penalty.



         (b) LIBOR. Borrower may prepay principal on any portion of this Note
             -----
which bears interest determined in relation to LIBOR at any time and in any
amount. In consideration of Bank providing this prepayment option to Borrower,
or if any such portion of this Note shall become due and payable at any time
prior to the last day of the Fixed Rate Term applicable thereto by acceleration
or otherwise, Borrower shall pay to Bank immediately upon demand a fee which is
the sum of the discounted monthly differences for each month from the month of
prepayment through the month in which such Fixed Rate Term matures, calculated
as follows for each such month:

          (i)     Determine the amount of interest which would have accrued each
                  ---------
                  month on the amount prepaid at the interest rate applicable to
                  such amount had it remained outstanding until the last day of
                  the Fixed Rate Term applicable thereto.

         (ii)     Subtract from the amount determined in (i) above the amount of
                  --------
                  interest which would have accrued for the same month on the
                  amount prepaid for the remaining term of such Fixed Rate Term
                  at LIBOR in effect on the date of prepayment for new loans
                  made for such term and in a principal amount equal to the
                  amount prepaid.

        (iii)     If the result obtained in (ii) for any month is greater than
                  zero, discount that difference by LIBOR used in (ii) above.

Borrower acknowledges that prepayment of such amount may result in Bank
incurring additional costs, expenses and/or liabilities, and that it is
difficult to ascertain the full extent of such costs, expenses and/or
liabilities. Borrower, therefore, agrees to pay the above-described prepayment
fee and agrees that said amount represents a reasonable estimate of the
prepayment costs, expenses and/or liabilities of Bank. If Borrower fails to pay
any prepayment fee when due, the amount of such prepayment fee shall thereafter
bear interest until paid at a rate per annum two percent (2.00%) above the Prime
Rate in effect from time to time (computed on the basis of a 360-day year,
actual days elapsed). Each change in the rate of interest on any such past due
prepayment fee shall become effective on the date each Prime Rate change is
announced within Bank.

EVENTS OF DEFAULT:

         The occurrence of any of the following shall constitute an "Event of
Default" under this Note:

         (a) The failure to pay, within 5 calendar days after the due date, any
principal, interest, fees or other charges hereunder or under any contract,
instrument or document executed in connection with this Note; provided however,
that with respect to interest, fees or other charges, no Event of Default shall
be deemed to have occurred if the same are paid later than the fifth day after
the applicable due date but within 30 days after the applicable due date no more
than two times during the term of this Note.

         (b) The filing of a petition by or against Borrower under any
provisions of the Bankruptcy Reform Act, Title 11 of the United States Code, as
amended or recodified from time to time, or under any similar or other law
relating to bankruptcy, insolvency, reorganization or other relief for debtors
(and, if filed against Borrower, the proceeding in question is not



dismissed within 60 days after its filing, provided further, that Bank shall not
be required to make advances during such 60 day period); the appointment of a
receiver, trustee, custodian or liquidator of or for any part of the assets or
property of Borrower; Borrower becomes insolvent, makes a general assignment for
the benefit of creditors or is generally not paying its debts as they become
due; or any attachment or like levy on any property of Borrower with a book
value of $5,000,000.00 or more.

         (c) The dissolution or liquidation of Borrower.

         (d) Any default in the payment or performance of any obligation, or any
defined event of default, under any provisions of any contract, instrument or
document pursuant to which Borrower has incurred (i) any obligation for borrowed
money, (ii) any purchase obligation, or (iii) any other liability of any kind to
any person or entity, including the holder, and, in the cases of (ii) or (iii)
                                            ---
the obligation or other liability exceeds $5,000,000.00, and, in the cases of
                                                         ---
(i), (ii) or (iii), the creditor has taken action(s) with respect to such
default, which action may consist solely of the sending of a notice of default.

         (e) Any financial statement provided by Borrower to Bank proves to be
incorrect, false or misleading in any material respect.

         (f) Any violation or breach of any provision of, or any defined event
of default under, any addendum to this Note or any loan agreement, guaranty,
security agreement, deed of trust, mortgage or other document executed in
connection with or securing this Note, and, if such violation or breach is by
                                       ---
its nature susceptible of being cured, the same is not cured within 30 days
after the date Borrower first knew (or, using reasonable due diligence, should
have known) thereof.

MISCELLANEOUS:

         (a) Remedies. Upon the occurrence of any Event of Default, the holder
             --------
of this Note, at the holder's option, may declare all sums of principal and
interest outstanding hereunder to be immediately due and payable without
presentment, demand, notice of nonperformance, notice of protest, protest or
notice of dishonor, all of which are expressly waived by Borrower, and the
obligation, if any, of the holder to extend any further credit hereunder shall
immediately cease and terminate. Borrower shall pay to the holder immediately
upon demand the full amount of all payments, advances, charges, costs and
expenses, including reasonable attorneys' fees (to include outside counsel fees
and all allocated costs of the holder's in-house counsel), expended or incurred
by the holder in connection with the enforcement of the holder's rights and/or
the collection of any amounts which become due to the holder under this Note,
and the prosecution or defense of any action in any way related to this Note,
including without limitation, any action for declaratory relief, whether
incurred at the trial or appellate level, in an arbitration proceeding or
otherwise, and including any of the foregoing incurred in connection with any
bankruptcy proceeding (including without limitation, any adversary proceeding,
contested matter or motion brought by Bank or any other person) relating to
Borrower or any other person or entity.

         (b) Governing Law.  This Note shall be governed by and construed in
             -------------
accordance with the laws of the State of California.



         IN WITNESS WHEREOF, the undersigned has executed this Note as of the
date first written above.
