      San Joaquin Bancorp Continues Growth in the Third Quarter

    BAKERSFIELD, Calif.--(BUSINESS WIRE)--Oct. 18, 2006--San Joaquin
Bancorp (OTCBB:SJQU), a bank holding company with $711 million in
assets, today announced financial results for the third quarter ended
September 30, 2006.

    Net income after tax for the third quarter was $1.9 million, a 14%
increase from $1.7 million in net income reported for the third
quarter of 2005. Earnings per share for the third quarter of 2006 were
$0.52 per diluted share compared to $0.46 per diluted share reported
in the third quarter of 2005, which is an increase of 13%.

    For the nine months ended September 30, 2006, net income after tax
was $6.7 million, an increase of 40% compared to $4.8 million in net
income reported for the same period in 2005. Earnings per share for
the period were $1.81 per diluted share compared to $1.31 per diluted
share reported through the third quarter of 2005, which is an increase
of 38%.

    Bart Hill, President and CEO said, "San Joaquin Bank is having
another excellent year of earnings and asset growth. The bank also
continues to be a leader in market share gains for Kern County
commercial bank deposits. San Joaquin Bank has a market share of 10.5%
and is the fourth largest of 22 FDIC insured institutions in the
county."

    Highlights for the Quarter Compared to Third Quarter 2005:

    --  Net income - up 14% to $1.9 million

    --  Loans, net of unearned fees - up 44% to $506 million

    --  Deposits - up 6% to $575 million

    --  Assets - up 20% to $711 million

    Income Statement

    Total interest income for the third quarter of 2006 was $12.2
million compared to $8.5 million reported in the same quarter 2005, an
increase of $3.7 million, or 44%. Strong loan demand and rising
interest rates were the primary driving factors while loan and
investment yields continue to improve. Average earning assets
increased from $525 million in the third quarter of 2005 to $636
million at the end of the third quarter of 2006 led by continued
strength in loan demand.

    Interest expense for the third quarter of 2006 was $4.9 million
compared to $2.6 million for the third quarter of 2005. Interest rate
increases accounted for approximately 52% of the change; however,
growth in money market and non-core funding comprised the remainder.

    Net interest margin increased in the comparative third quarters
from 4.48% in 2005 to 4.53% in 2006. The rise is the result of growth
in earning assets, primarily loans, which carry more favorable yields.
Improvement in investment yields also contributed.

    Non-interest income was $725,000 for the third quarter of 2006
compared to $680,000 for the same period in 2005. The improvement was
due to an increase in other customer service fees. Fees from deposit
accounts were down $24,000 compared to the third quarter in 2005.

    Non-interest expense was $3.8 million for the third quarter of
2006 compared to $3.3 million in the same period of 2005. Increases in
salaries and employee benefits, including normal adjustments and staff
additions, account for most of the change. The Company's efficiency
ratio improved on a year over year basis from 50.26% in the third
quarter 2005 to 48.08% in 2006, demonstrating increases in overall
operating efficiency as compared to the prior year.

    In the third quarter of 2006, the provision for loan losses was
increased to $600,000 compared to $300,000 in 2005. The additional
provision was prompted by significant growth in the loan portfolio.
Allowance for loan loss adequacy is determined by the application of
various factors such as historical loss and industry default rates,
peer group comparisons, and loan quality classifications.

    Annualized return on average assets decreased from 1.18% in the
third quarter 2005 compared to 1.11% for the same period in 2006.
Return on average equity decreased from 18.46% in 2005 to 17.01% in
2006 on an annualized basis. The decline is due primarily to
additional provision for loan losses.

    Balance Sheet

    Total loans, net of unearned fees, increased $155 million to $506
million, or 44%, compared to $351 million at the end of the third
quarter of 2005. The increase was primarily attributable to growth in
loans on existing commercial real estate and construction and land
development.

    As of September 30, 2006, total deposits were $575 million as
compared to $543 million at September 30, 2005. The increase of $32
million, or 6%, was primarily due to growth in money market accounts.
Interest-bearing deposits increased by $36 million while
noninterest-bearing deposits declined by $4 million.

    For the Bank, non-core funding consisting of time deposits of
$100,000 or more, Federal Home Loan Bank (FHLB) advances and other
borrowings, increased as strong loan demand outpaced deposit growth.
FHLB advances made up the majority of the increase. At September 30,
2006, non-core funds were $99 million compared to $26 million at
September 30, 2005. Non-core funding accounted for approximately 15%
of total funding at September 30, 2006.

    Asset Quality

    The Company had net recoveries of previously charged off loans of
$66,000 in the first nine months of 2006 compared to $277,000 net
charge-offs for the same period in 2005. The allowance for loan losses
was $8.2 million and $6.1 million or 1.62% and 1.74% of loans at
September 30, 2006 and 2005, respectively.

    Nonperforming and restructured loans were $330,000 at September
30, 2006, compared to $3.4 million at September 30, 2005. The
percentage of nonperforming and restructured loans to total loans, net
of unearned income, was .07% at the end of the third quarter of 2006
compared to .97% at the end of the third quarter in 2005.

    Total nonperforming and restructured assets were $1.0 million at
September 30, 2006, compared to $4 million at September 30, 2005.
Nonperforming and restructured assets as a percentage of total assets
were 0.14% and 0.67% at the third quarter of 2006 and 2005,
respectively.
