North Valley Bancorp Reports Second Quarter Results

July 21, 2005 - REDDING, CA - North Valley Bancorp (NASDAQ:NOVB), a multi-bank
holding company with $899 million in assets, today reported results for the
three and six-month periods ending June 30, 2005. North Valley Bancorp ("the
Company") is the parent company for North Valley Bank ("NVB"), and NVB Business
Bank ("NVBBB" formerly named Yolo Community Bank).

Second Quarter Results

         The Company reported net income for the quarter ended June 30, 2005 of
$1,987,000 or $0.26 per diluted share compared to $1,982,000 or $0.29 per
diluted share for the same period in 2004.

         Net interest income, which represents the Company's largest component
of revenues and is the difference between interest earned on loans and
investments and interest paid on deposits and borrowings, increased $2,814,000
or 38.8% for the quarter ended June 30, 2005 compared to the same period in
2004. This was due to an increase in interest income of $3,261,000 partially
offset by an increase in interest expense of $447,000. The increase in interest
income was due to an increase in total average outstanding loans from
$410,383,000 in the second quarter of 2004 to $581,858,000 in the same period
this year (an increase of $171,475,000 or 41.8%). Of the $171,475,000 increase
in outstanding average loans, $93,096,000 was due to the acquisition of NVBBB in
August 2004. The increase in average total loans was funded with an increase in
average total deposits of $124,240,000, and an increase in average borrowings of
$20,093,000. Average yields on earning assets increased 62 basis points up to
6.32% for the second quarter of 2005 and the average rate paid on
interest-bearing liabilities increased by 4 basis points to 1.38% compared to
the second quarter of 2004. The increase in asset yields was primarily due to
the increase in total loans coupled with an increase in average loan yields,
which increased from 6.61% in the second quarter of 2004 to 7.10% in the same
period in 2005. The Company's Net Interest Margin for the quarter ending June
30, 2005 was 5.21%, an increase of 63 basis points over the second quarter of
2004.

         Non-interest income was $2,463,000 in the second quarter of 2005
compared to $2,250,000 for the same period in 2004. Service charges on deposits
decreased from $1,194,000 in the second quarter of 2004 to $1,189,000 in the
second quarter of 2005. The Company recorded $54,000 in gains on mortgage loan
sales. The Company is currently selling its fixed-rate mortgage production in
order to maintain a loan portfolio with a shorter overall duration. Earnings on
cash surrender value of life insurance policies increased from $271,000 in the
second quarter of 2004 to $287,000 in the second quarter of 2005. Other
non-interest income increased $79,000 from 2004 levels due mainly to increased
sales of third-party investment products.

         Non-interest expense totaled $9,463,000 for the three months ending
June 30, 2005 compared to $6,660,000 for the same period in 2004 an increase of
$2,803,000 or 42.1%. Salaries and benefits increased by $1,220,000 or 35.1% over
the second quarter of 2004 due to the acquisition of NVBBB in August 2004.
Occupancy expense increased from $454,000 in the second quarter of 2004 to
$692,000 in the same period in 2005 and other expense increased from $2,222,000
in the second quarter of 2004 to $3,667,000 in the second quarter of 2005, both
increases were also due to the acquisition NVBBB's operations.

Linked Quarter Results

         Net interest income increased by $470,000 (20% annualized) from the
first quarter of 2005 to the second quarter of 2005. This was the result of
increased interest income generated by higher loan totals and an improved Net
Interest Margin of 5.21%, up from 4.96% in the first quarter of 2005.
Non-interest income remained relatively stable for the second quarter of 2005.

                                       3


         Non-interest expense increased from $8,434,000 for the first quarter of
2005 to $9,463,000 for the second quarter of 2005 in part as a result of the
opening of new offices in Fairfield, Santa Rosa and Ukiah. Additionally, the
Company incurred one-time costs of $325,000, which related to the roll-out of
the new NVB brand.

         Net loans outstanding increased from $566,024,000 in the first quarter
of 2005 to $591,477,000 in the second quarter of 2005 or 18% annualized.
Deposits decreased $15,925,000 between the first and second quarters of 2005,
primarily as a result of a single relationship, however, non-interest demand
deposits increased by $9,405,000 between the first and second quarters as a
result of new relationships opened at the NVB Business Bank branches.

Year-to-Date Results

         For the six months ended June 30, 2005, the Company reported net income
of $4,246,000 or $0.55 per diluted share compared to $4,056,000 or $0.59 per
diluted share for the same period in 2004. This represents an increase in net
income of $190,000 but a decrease in earnings per share of $0.04. Non-interest
income increased $202,000 in the six months ended June 30, 2005 compared to
2004. Net interest income increased $5,368,000, or 37.5% in the six months ended
June 30, 2005 compared to 2004 and non-interest expense increased by $4,647,000
or 35.1% over the same period last year.

Credit Quality

         Non-Performing loans (defined as non-accrual loans and loans 90 days or
more past due and still accruing interest) decreased $730,000 to $1,440,000 or
0.24% of total loans at June 30, 2005 from $2,170,000 or 0.39% of total loans at
December 31, 2004. The allowance for loan and lease losses at June 30, 2005 was
$7,612,000 or 1.27% of total loans compared to $7,217,000 or 1.30% of total
loans at December 31, 2004. The ratio of net (recoveries) charge-offs to average
loans outstanding for the three months ended June 30, 2005 was (0.01)% compared
to 0.06% for the same period in 2004. The Company recorded a provision for loan
losses of $450,000 for the six months ending June 30, 2005 compared to no
provision for the similar period of 2004. While the overall credit quality of
the loan portfolio remains strong the provision was supported primarily by the
growth in the commercial lending portfolio. The allowance for loan and lease
losses as a percentage of nonperforming loans was 528.61% as of June 30, 2005
compared to 332.58% as of December 31, 2004.

         "The Company discontinued its indirect Dealer Financing Program during
the quarter as loan yields declined and competition increased. The portfolio is
expected to payoff during the next 24 months thereby providing additional
funding capacity for new business", stated Mike Cushman, President & CEO.

Summary

         Mike Cushman, President and CEO, commented as follows:

         "The second quarter of 2005 saw the final integration of NVB Business
Bank, the opening of new offices in Fairfield, Santa Rosa and Ukiah and the
hiring of key personnel in all Business Bank markets. Additionally, the new NVB
brand was introduced, eliminating the Six Rivers Bank and Yolo Community Bank
names thereby providing for greater efficiency and brand recognition."

         "We have made a significant investment in growing the Company through
the NVB Business Bank acquisition and the opening of new branches in some of the
state's most rapidly growing markets. This investment has resulted in higher
non-interest expenses in the short run which we expect to stabilize and be
off-set by increasing revenues in the future."

         "North Valley Bancorp has achieved a major strategic goal with the
addition of new offices, fully staffed by experienced professionals in most of
Northern California's major markets. It has taken us a number of years to
achieve this goal. We believe that our financial position going forward will be
further strengthened by an expanding Net Interest Margin and by maintaining
excellent asset quality", stated Mike Cushman, President and CEO.
