   NORTH BAY BANCORP ANNOUNCES SECOND QUARTER 2003 FINANCIAL RESULTS EARNINGS
                                  INCREASE 15%

Napa, CA - July 28, 2003 - North Bay Bancorp (Nasdaq: NBAN), holding company for
The Vintage  Bank and Solano Bank,  today  announced  financial  results for the
three months and six months ended June 30, 2003.

Net income for the three months ended June 30, 2003 was $1,012,000,  or $.44 per
share  (diluted),  as compared  with net income of  $877,000,  or $.39 per share
(diluted),  for the second  quarter of 2002,  representing  a 15% increase.  Net
income for the six months ended June 30, 2003 was $1,907,000,  or $.82 per share
(diluted),  compared with net income of $1,655,000. or $.74 per share (diluted),
for the first six months of 2002, also representing a 15% increase. Total assets
were  $435,444,000  as of June 30,  2003,  equating  to  growth  of 20% over the
preceding  twelve months.  Total assets grew by  approximately  $16 million from
March 31, 2003.

"North  Bay  Bancorp  continues  on track with its  business  plan  despite  the
challenges  presented by our unprecedented  interest rate  environment,"  stated
Terry Robinson,  President & CEO. "We remain  optimistic  regarding the earnings
prospects for the remainder of the year given our current strong loan volume."

FINANCIAL HIGHLIGHTS

Earnings

Net interest  income for the second quarter of 2003 increased  $343,000,  or 8%,
compared  with the second  quarter of 2002.  Year-to-date  net  interest  income
increased  $853,000,  or 10%.  The net  interest  margin has  decreased to 4.91%
during the first  half of 2003 from an  average of 5.31% for the year 2002.  The
major  factor   contributing  to  the  declining  margin  was  lower  yields  on
investments  and loans;  rates paid on deposits did not reflect a  corresponding
decline.

Noninterest  income for the second  quarter of 2003 increased  $83,000,  or 13%,
compared  with the  second  quarter  of 2002.  Year-to-date  noninterest  income
increased  $159,000,  or  12%,  compared  with  the  first  half of  2002.  Most
noninterest income was derived from service charges on deposit accounts. Service
charge income  increased  proportionately  less than the growth in deposits,  as
deposit growth was attributed primarily to an increase in the average balance of
deposit  accounts  during the previous  twelve months rather than an increase in
the number of new  accounts.  Also,  a  restructuring  of the  checking  account
product line during the first quarter

                                                                               4


of 2003 resulted in a higher portion of checking  accounts which do not generate
service charges.

Gains on securities transactions were $331,000 during the second quarter of 2003
compared  with  no  securities   gains  during  the  second   quarter  of  2002.
Year-to-date  securities  gains were $430,000  compared to $66,000 for the first
half of 2002. The  securities  gains  recognized  during the 2003 second quarter
resulted  primarily  from the sale of  securities  within a year of  maturity to
provide funding for loans in process.

Noninterest  expense for the second quarter of 2003 increased  $856,00,  or 25%,
compared with the second quarter of 2002.  Year-to-date  noninterest expense for
2003  increased  $1,504,000,  or 22%, from 2002. The  disproportionate  increase
during the second quarter was primarily due to legal fees incurred in connection
with  litigation with our former host system  provider;  the case was settled in
June, 2003. The year-to-date  increase was due primarily to a combination of the
litigation-related  legal fees, a 17% increase in salaries and employee benefits
resulting  from  increased  staffing  and a 27%  increase in  occupancy  expense
resulting  from the  addition  of a bank  branch  office and new  administrative
offices both of which were occupied in March, 2003.

Balance Sheet

Total assets were $435.4  million as of June 30, 2003, a 20% increase  from June
30, 2002.  Deposits grew $67 million,  or 21% while loans,  net of the allowance
for loan losses, grew $49.5 million, or 24%, during the twelve months ended June
30, 2003.

Liquidity levels significantly exceeded policy requirements throughout the year.
As of June 30, 2003 liquid assets represented 31% of total assets.

Asset quality  remains  excellent.  As of June 30, 2003,  the allowance for loan
losses was $3.4 million,  or 1.3% of loans  outstanding.  No loan loss provision
was accrued  for The  Vintage  Bank during the first half of 2003 based upon our
revised loan loss reserve  analysis;  $90,000 was expensed for the  provision at
Solano Bank. Net  charge-offs  were a nominal $7,000 for the first half of 2003.
There were no nonperforming loans as of June 30, 2003.

OUTLOOK

Regarding  the outlook for 2003,  Robinson  stated,  "We are  optimistic  that a
strong second half will enable us to meet our net income  projections  for 2003.
Elements of  noninterest  expense,  particularly  legal and  professional  fees,
should decline  significantly the remainder of the year. We are currently adding
quality loans to our balance sheet at a rate outpacing deposit growth,  which is
the best antidote for our current difficult rate environment."
