                                  NEWS RELEASE

        NORTH BAY BANCORP ANNOUNCES FIRST QUARTER 2003 FINANCIAL RESULTS

Napa, CA - May 2, 2003 - North Bay Bancorp (Nasdaq:  NBAN),  holding company for
The Vintage  Bank and Solano Bank,  today  announced  financial  results for the
three months ended March 31, 2003.

Net  income  for the  first  quarter  of 2003 was  $895,000  , or $.39 per share
(diluted), as compared with net income of $778,000, or $.35 per share (diluted),
for the first quarter of 2002, representing a 15% increase in net income for the
first quarter of 2003 compared with the first quarter of 2002. Total assets were
$419,594,000 as of March 31, 2003,  equating to growth of 24% over the preceding
twelve months. Total assets grew by approximately $3 million from year-end 2002.

"North Bay Bancorp  continues on schedule with our business  plan," stated Terry
Robinson,  President & CEO. "We opened our ninth office in March  2003--the  new
Gateway  Office of The Vintage  Bank,  located on Airport Road in Southern  Napa
County.  Total assets grew during the first quarter  despite the normal seasonal
runoff in  deposits.  Our asset  quality  remains  excellent,  and our  earnings
outlook remains positive despite a slow economy and intense price competition."


FINANCIAL HIGHLIGHTS

Earnings
Net interest  income for the first quarter of 2003 increased  $510,000,  or 13%,
compared  with the first  quarter of 2002.  The net  interest  margin  decreased
during  the first  quarter  of 2003,  to 4.98% from an average of 5.31% for year
2002.  The major factor in the declining  margin was lower yields on investments
and loans; rates paid on deposits did not reflect a corresponding decline.

Noninterest  income for the first  quarter of 2003  increased  $76,000,  or 12%,
compared with the first quarter of 2002.  Most  noninterest  income derives from
service   charges  on  deposit   accounts.   Service  charge  income   increased
proportionately  less than the growth in deposits due to the average  balance of
deposit  accounts  increasing  during the previous  twelve months,




resulting  in  fewer  accounts  generating  service  charges.   Also,  a  recent
restructuring  of the checking account product line resulted in a higher portion
of checking accounts generating no service charges.

Gains on securities  transactions  were $99,000 during the first quarter of 2003
compared  with $66,000  during the first quarter of 2002.  These gains  resulted
from our established  practice of selling selected  securities prior to maturity
and reinvesting  funds  longer-term in order to maintain  yields;  this practice
normally  results  in  recognized  securities  gains  when  the  yield  curve is
"positive".

Noninterest  expense for the first quarter of 2003 increased  $648,000 , or 19%,
compared with the first quarter of 2002.  The largest  component of the increase
was in Salaries  and  Benefits,  which rose 21%,  primarily  due to increases in
full-time  equivalent (FTE) employees.  The FTE increases  related to increasing
sales activity and staffing new offices. Other components of noninterest expense
that increased materially were legal and professional fees. Legal fees increased
primarily due to ongoing  litigation  with our former host system provider while
professional  fee increases  were  primarily  related to outsourced  information
technology services.

Balance Sheet

Total assets were $419.6  million as of March 2003,  a 24%  increase  from 2002.
Deposits  grew $67  million,  or 22%,  while loans grew $58.5  million,  or 30%,
during the twelve months ended March 31, 2003.

Liquidity levels significantly exceeded policy requirements throughout the year.
As of March 31, 2003 liquid assets represented 32% of total assets.

Asset quality  remains  excellent.  As of March 31, 2003, the allowance for loan
losses was $3.3 million,  or 1.3% of loans  outstanding.  No loan loss provision
was accrued for The Vintage Bank during the quarter  based upon our revised loan
loss reserve  analysis;  $45,000 was expensed for the  provision at Solano Bank.
Net  charge-offs  were a nominal  $8,000  for the  first  quarter  of 2003,  and
non-performing loans totaled $312,000 as of March 31, 2003.

OUTLOOK

Regarding the outlook for 2003,  Robinson stated, "We believe we are on track to
meet our net  income  projections  for 2003.  We  anticipate  that  elements  of
noninterest  expense will decline the  remainder of the year.  The extent of our
earnings  growth  will be  impacted  by our  ability to  continue to add quality
assets and maintain yields in the face of a slow economy and increasing  pricing
competition."
