from $6,617,000 for the nine months ended September 30, 2005.

"American River Bankshares has been able to show improvement in a very
challenging banking environment," said David T. Taber, President and CEO of
American River Bankshares. "We didn't let the fact that second quarter earnings
were below our expectations change our direction with the strategic plan and as
a result, are encouraged by our effort in the third quarter."

Net interest income for the third quarter of 2006 increased 1.5% to $6,798,000
from $6,699,000 for the second quarter of 2006 and increased 0.7% from

margin as a percentage increased to 5.03% from 4.95% for the nine months ended
September 30, 2005.

months ended September 30, 2006, noninterest expense increased 6.5% to
$10,862,000 from $10,195,000. This increase is primarily related to higher
personnel costs (up $415,000 or 7.9% excluding FAS 123 (R) related costs),
occupancy expense (up $88,000 or 5.6%), professional fees (up $47,000 or 8.4%)
and costs associated with adopting FAS 123(R) ($160,000).

Net loans as of September 30, 2006 decreased $17,779,000 (4.5%) to $374,396,000

June 30, 2006 but decreased $25,211,000 (4.9%) from $518,655,000 as of September
30, 2005. From December 31, 2005, total deposits decreased $7,262,000 (1.5%)
from $500,706,000. Short-term borrowings decreased 55.0% to $25,566,000 at

up 35.6% from $18,860,000 at September 30, 2005.

"Our net interest margin is back above 5%, due in large part to the fact that we
were able to cut short-term borrowings in half over last quarter," said Mr.
Taber. "We accomplished this major shift by working hard to increase core
deposits, while at the same time decreasing our investment portfolio."
