             NORTH BAY BANCORP ANNOUNCES YEAR 2002 FINANCIAL RESULTS
                    ASSETS GROW 27%, NET INCOME INCREASES 23%

Napa, CA - February 18, 2003 - North Bay Bancorp (Nasdaq: NBAN), holding company
for The Vintage Bank and Solano Bank, today announced  financial results for the
quarter and year ended December 31, 2002.

Net income for the quarter ended December 31, 2002 was  $1,126,000,  or $.49 per
share  (diluted),  as compared  with net income of  $928,000,  or $.45 per share
(diluted),  for the fourth quarter of 2001. Net income was $3,708,000,  or $1.64
per share  (diluted),  for the year ended December 31, 2002 as compared with net
income of $3,022,000, or $1.39 per share (diluted), for year 2001. These results
represent a 21% increase in net income for the fourth  quarter of 2002  compared
with the  corresponding  quarter  of 2001 and a 23%  increase  for the year 2002
compared  with 2001.  Total  assets were  $416,458,000  as of December 31, 2002,
equating to growth of 27% for the year.

"North Bay Bancorp has effectively  executed its business plan throughout 2002,"
stated Terry Robinson, President & CEO. "We opened two new offices in January of
2002,  closed a $10 million trust  preferred  offering in June and completed our
Nasdaq  National  Market listing in September.  We achieved our growth goals and
finished the year within 3% of meeting our net income targets.  In the course of
the year, we absorbed some significant non-recurring legal and professional fees
related to our Nasdaq  listing,  the trust preferred  offering,  revised benefit
plans and new regulatory  requirements  for public  companies.  We completed the
year  with only a  nominal  decline  in our net  interest  margin  and our asset
quality remains  excellent,  with no non-accrual or  non-performing  loans as of
December 31, 2002."

FINANCIAL HIGHLIGHTS

Earnings

Net interest income for year 2002 increased  $3,068,000,  or 21%,  compared with
2001. The net interest margin decreased nominally during the year, from 5.36% in
2001 to 5.31% in 2002. A major factor in the declining margin was deposit growth
at The Vintage Bank  outpacing loan growth,  ending 2002 with a  loan-to-deposit
ratio of 60%.

Noninterest income for year 2002 increased $347,000, or 15%, compared with 2001.
Most  noninterest  income  derives  from  service  charges on deposit  accounts.
Service  charge income  increased  proportionately  less than growth in deposits
because  the  average  balance of deposit  accounts  increased  during the year,
resulting in fewer accounts generating service charges.


Gains on securities transactions were $399,000 in 2002 compared with $325,000 in
2001.  These gains resulted from our  established  practice of selling  selected
securities  prior to maturity  and  reinvesting  funds  longer-term  in order to
maintain yields; in a falling-rate environment this practice normally results in
recognized securities gains.

Noninterest  expense for year 2002 increased  $2,362,000,  or 20%, compared with
2001. The largest component of the increase was in Salaries and Benefits,  which
rose 24%,  primarily due to increases in full-time  equivalent  (FTE) employees.
The FTE increases related to increasing sales activity, staffing new offices and
positioning  for future growth.  Other  components of  noninterest  expense that
increased  materially  were  insurance  costs and legal  and  professional  fees
associated  with our  Nasdaq  listing,  our trust  preferred  offering,  revised
benefits plans, new corporate  governance  legislation and changes in regulatory
requirements.

Balance Sheet

Total assets grew $89.7 million to $416.5 million as of December 31, 2002, a 27%
increase from 2001.  Deposits grew $75.4 million, or 26%, while loans grew $50.8
million, or 28%.

Liquidity levels significantly exceeded policy requirements throughout the year.
As of December 31, 2002 liquid assets represented 38% of total assets.

Asset quality remains excellent. As of December 31, 2002, the allowance for loan
losses was $3.3 million,  or 1.38% of loans outstanding.  During 2002,  $576,000
was charged to expense for the provision for loan losses  compared with $447,000
in 2001.  There were no  nonperforming  or  nonaccrual  loans as of December 31,
2002. Net charge-offs for the year totaled $3,000.

OUTLOOK

Regarding the outlook for 2003, Robinson stated, "We have consistently predicted
that 2003 would be the year we would witness the initial  financial  payoff from
the aggressive growth strategy commenced in 1999 with the organization of Solano
Bank.  We  are  now   positioned  to  grow   substantially   with  our  existing
infrastructure  while  requiring  only  nominal  increases  in  numbers  of  FTE
employees. We project another year of substantial asset growth for 2003 with our
increase in net income exceeding asset growth on a percentage basis."
