            NORTH BAY BANCORP'S SECOND QUARTER PROFITS INCREASE 31%,

             LOAN PORTFOLIO GROWS 19% AND CORE DEPOSITS INCREASE 16%


Napa, CA - July 26, 2005 - North Bay Bancorp (Nasdaq: NBAN), holding company for
The Vintage Bank and its Solano Bank division,  today announced profits grew 31%
in the second  quarter of 2005 with 19% growth in the loan  portfolio  and a 16%
increase in core deposits from the year previous levels. Net income totaled $1.6
million,  or $0.39 per  diluted  share in the second  quarter,  compared to $1.2
million, or $0.31 per diluted share in the second quarter of 2004. For the first
six months of 2005,  net income grew 36% to $3.0  million,  or $0.75 per diluted
share, compared to $2.2 million, or $0.57 per diluted share in the first half of
2004.

"Our second quarter results are consistent with our plan, formulated in 2004, to
focus on improving  efficiency  and  profitability.  Our asset  quality  remains
excellent,  our net  interest  margin is strong and we  continue  to advance our
expense  management  skills,"  commented  Terry  Robinson,  President  and  CEO.
Robinson added, "A major factor that will continue to adversely  impact earnings
through  the  remainder  of  2005  is  the  cost  of  services  associated  with
Sarbanes-Oxley Section 404 compliance."

6/30/05 compared to 6/30/04)

     o Net income increased 31% to $1.6 million.

     o Pre-tax income rose 33% to $2.6 million.

     o Revenues, excluding securities gains, increased 24% to $8.0 million.

     o Total loans grew 19% to $403 million.

     o Asset quality remained exemplary with no nonperforming  assets at quarter

                                Operating Results


Revenues, consisting of net interest income before the provision for loan losses
and  non-interest  income  excluding  securities  gains,  increased  24% to $8.0
million in the second quarter of 2005 from $6.4 million in the second quarter of
2004.  In the first half of 2005,  revenues  increased 22% to $15.6 million from
$12.8 million in the first half of 2004.

                                       4


Net interest income  increased 28% to $7.0 million in the second quarter of 2005
compared  to $5.4  million in the second  quarter  year of 2004,  with  interest
income growing 29% and interest expense up 36%. In the first six months of 2005,
net interest  income rose 26% to $13.6  million from $10.8  million in the first
half of 2004.  Although  there are no  nonperforming  loans,  the second quarter
provision  for loan losses  increased  to $230,000  from  $174,000 in the second
quarter  of last year to  provide  for  growth in the  overall  loan  portfolio.
Year-to-date, the loan loss provision increased to $415,000 from $360,000 in the
first half of 2004.  Second quarter net interest  income after the provision for
loan losses increased 28% to $6.7 million compared to $5.3 million in the second
quarter the previous year and grew 26% to $13.2 million in the first half of the
year from $10.5 million in the first half of 2004.

The net interest  margin  increased to 5.31% in the second quarter from 4.80% in
the second  quarter of 2004.  In the first six months of 2005,  the net interest
margin was 5.30%  compared  with 5.01% for the first half of 2004.  The improved
margin is attributed to a higher  loan-to-deposit  ratio,  increased yields from
variable  rate  loans,  an  improved  deposit  mix  and  prudent  management  of
increasing rates paid on deposits.

Non-interest income, excluding securities gains, increased 3% to $1.0 million in
the second quarter of 2005. Year-to-date,  non-interest income was slightly less
than the  first six  months  of 2004  primarily  due to a  decline  in  revenues
generated from consumer overdraft activity.

                            NBAN 2Q05 Profits Up 31%
                            ------------------------


Non-interest  expenses  in the  second  quarter  of 2005  increased  13% to $5.2
million from $4.6 million in the second quarter of 2004. In the first six months
of 2005,  operating expenses increased 11% to $10.2 million from $9.2 million in
the like period of 2004.  The percentage  increase in expenses is  significantly
less  than  the  comparable  increase  in  revenues  primarily  due to a  modest
percentage   increase  in  salaries  and  benefits  resulting  from  maintaining
full-time  equivalent  employee levels very close to previous year levels.  This
benefit was partially  offset by  significant  increases in consulting and audit
fees due to the Company's requirement for Sarbanes-Oxley  Section 404 compliance
in 2005. The tax equivalent  efficiency  ratio in the second quarter improved to
63.89%  compared to 67.15% in the second quarter last year and dropped to 64.70%
in the first half of 2005 from 68.90% in the first half of 2004.  The efficiency
ratio measures non-interest expenses as a percent of revenues.

Pre-tax Income  increased 33% in the second quarter of 2005 to $2.6 million from
$1.9 million the second  quarter of 2004.  Pre-tax  income rose 40% in the first
half of the year to $5.0 million from $3.5 million in the first half of 2004.

Income taxes increased in the second quarter of 2005 reflecting higher earnings.
The tax provision  increased to $1.0 million,  or 39% of second quarter  pre-tax
income,  compared to $740,000,  or 38% of second  quarter  pre-tax income a year
ago. For the first half of 2005,  the provision for income tax was $1.9 million,
or 38% of pre-tax income,  compared to $1.3 million, or 36% of pre-tax income in
the first half of 2004.  The increase in the effective tax rate in 2005 compared
with 2004 was due to a declining  level of tax free income from municipal  bonds
in the investment portfolio.

Earnings  ratios  improved with return on equity and return on assets up for the
second quarter and first six months of 2005. "As predicted, we are now realizing
efficiencies from changes identified  approximately a year ago," Robinson noted.
North Bay generated a return on average  equity of 13.65% in the second  quarter
and  13.34% in the first  half of 2005  compared  to  12.05%  and  11.43% in the
respective  periods of 2004.  Return on  average  assets was 1.09% in the second
quarter  and 1.08% in the first  half of 2005  compared  to 0.95% in the  second
quarter and 0.92% in the first half of 2004.
