         American River Bankshares Announces First Quarter 2008 Earnings

Sacramento, CA, April 17, 2008 - American River Bankshares (NASDAQ-GS: AMRB)
today reported diluted earnings per share, as adjusted for the 5% stock dividend
distributed in December 2007, for the first quarter of 2008 of $0.33, a 5.7%
decrease from $0.35 recorded in the first quarter of 2007. Net income for the
first quarter of 2008 decreased $253,000 (12.1%) to $1,833,000 from $2,086,000
during the first quarter of 2007.

"Clearly, first quarter earnings were negatively impacted by the $4 million
increase from year end in our non-performing loans to nearly $12 million," said
David Taber, President and CEO of American River Bankshares. "We have a seasoned
credit administration team in place that is managing our non-performing loans by
establishing appropriate reserves and being proactive towards resolution of
these credits."

Net Interest Margin
Net interest margin as a percentage was 4.94% for the first quarter of 2008
compared to 5.04% for the first quarter of 2007. Net interest income for the
first quarter of 2008 decreased 3.1% to $6,342,000 from $6,547,000 for the first
quarter of 2007. Interest income for the first quarter of 2008 decreased 9.4% to
$8,578,000 from $9,464,000 for the first quarter of 2007. The average yield on
earning assets declined from 7.26% in the first quarter of 2007 to 6.66% for the
first quarter of 2008. Much of the decline in yields can be attributed to the
overall lower interest rate environment, in response to the Federal Reserve
Board (the "FRB") decreases in the Federal funds and discount rates. Decreases
by the FRB have resulted in a 300 basis point decline in short-term interest
rates since September 2007. The average balance of earning assets also decreased
from $533,645,000 in the first quarter of 2007 to $523,520,000 in the first
quarter of 2008. The decrease in average earning assets was based on the
Company's decision to use the proceeds from principal reductions and maturing
investment securities to reduce the level of higher cost time deposits and
provide funding for loan growth. This strategy has reduced the average balances
on investment securities by 18.6% from $141,045,000 during the first quarter of
2007 to $114,045,000 during the first quarter of 2008. An increased level of
non-accrual loans negatively impacted the yield on loans by approximately 26
basis points, which declined from 8.22% in the first quarter of 2007 to 7.22%
for the first quarter of 2008.

Interest expense for the first quarter of 2008 decreased 23.4% to $2,236,000
from $2,917,000 for the first quarter of 2007. The average cost of funds
declined from 3.18% in the first quarter of 2007 to 2.38% for the first quarter
of 2008. The average balance of interest bearing liabilities increased from
$371,733,000 in the first quarter of 2007 to $378,114,000 in the first quarter
of 2008. The Company continues to focus on attracting lower cost business
relationships, particularity business checking and money market accounts. In
addition, the Company has taken advantage of the lower borrowing rates by
locking in one to two year funding from its financial partners and letting
maturing time deposits, that were seeking above market rates, run-off.

Loan Growth and Asset Quality
Net loans as of March 31, 2008 increased $3,449,000 (0.9%) from December 31,
2007 and increased $18,778,000 (4.9%) to $398,424,000 from $379,646,000 as of
March 31, 2007. The largest growth was in commercial loans, which increased
$4,086,000 (3.9%) to $109,553,000 as of March 31, 2008 from $105,467,000 as of
December 31, 2007 and increased $22,124,000 (25.3%) from $87,429,000 as of March
31, 2007.

"Aside from additional work needed on our non-performing loans, we continue to
gain momentum with our strategic plan," said Mr. Taber. "Business loans and
loans to finance facilities for business purposes are all up from year end."

He continued, "Because of our strong team of credit administration
professionals, the rest of our team is able to keep focused on building
relationships with clients and prospects. It's important to the continued
success of our Company that we have been able to remain in expansion mode."

compared with $5,883,000 at December 31, 2007 and $5,935,000 at March 31, 2007.
The provision for loan and lease losses was $337,000 for the first quarter of
2008, compared to $135,000 for the fourth quarter of 2007 and $121,000 for the
first quarter of 2007. The allowance as a percentage of loans and leases was

March 31, 2007. Net chargeoffs for the first quarter of 2008 were $203,000
compared to $60,000 for the first quarter of 2007. Non-performing loans and
leases as of March 31, 2008 were 2.89% of total loans and leases compared to
1.86% at December 31, 2007 and 0.20% one year ago.

Non-performing assets were $11,688,000 at March 31, 2008 compared to $7,501,000
at December 31, 2007 and $766,000 at March 31, 2007. At March 31, 2008, three
loan relationships made up $10,371,000 or 88.7% of the non-performing assets. Of
these three relationships two continue from last quarter, the $1,352,000
development loan for residential lots and the $5,286,000 loan for a mini storage
facility. In April 2008, the Company confirmed that the borrower on the mini
storage facility loan had filed for reorganization under Chapter 11 bankruptcy.
The business has appointed new management and we have received a budget
projection indicating their ability to service our loan at a market rate of
interest. During the first quarter of 2008 the Company added an additional
relationship in the amount of $3,734,000. This relationship is made up of eight
individual loans to a developer and includes loans on three finished homes
totaling $2,242,000; one partially competed home for $493,000, and four finished
lots for $999,000. In April 2008, the Company filed notices of default on all
eight properties.

$485,744,000 as of March 31, 2007. The increase during the first quarter of 2008
compared to December 31, 2007 was primarily the result of an increase in
interest checking and money market accounts from $170,974,000 at December 31,
2007 to $177,242,000 at March 31, 2008--an increase of $6,268,000 or 3.7%. Even
