                              Pacific State Bancorp
                               Fourth Quarter 2004
                      Earnings and Performance Announcement

Stockton, CA (February 4, 2005) - Steven A. Rosso, President and Chief Executive
Officer, today announced Pacific State Bancorp's (the "Company") fourth quarter
2004 earnings and performance ratios.

The fourth quarter of 2004 produced moderate asset growth of $3,825,085 or 1.53%
compared to the third quarter of 2004. The loan portfolio increased by
$11,291,652, and the investment portfolio increased by $5,269,870 or 32.47%.
These increases were funded by a decrease in Federal funds sold of $13,375,000
and an increase in deposits of $4,748,853 or 2.17%. The deposit mix was reshaped
by an increase in interest bearing transactional accounts of $10,789,428 or
12.97%. The level of non-interesting bearing accounts remained stable comprising
23.23% of total deposits. Certificates of Deposits declined by $6,840,765 or
8.82%. The Company also reduced short-term borrowing by $1,000,000 in the fourth
quarter of 2004.

The net effect of the Company's loan and investment portfolio growth, along with
strong growth in loan fees and the change in the mix of deposits resulted in a
rise in the net interest margin to 5.14% for the fourth quarter of 2004. This
represents an increase of 1.10% from the 4.04% net interest margin for the third
quarter of 2004. Assets quality continued to be good, with no loans 30 days past
due and no non-performing assets.

The fourth quarter earnings of $831,461 or $0.24 basic earnings per share and
$0.23 diluted earnings per share was slightly below the third quarter of 2004
down $62,712, or $0.02 basic earnings per share. While net interest income
increased by $675,042 in the fourth quarter of 2004 from the third quarter,
non-interest income fell $305,060 to $512,816. This was primarily the result of
a decrease in loan sales, service changes and other income.. As a result, net
income before taxes increased $30,887 for the period. Additional accrual for
income taxes for the fourth quarter of 2004 of $93,550 resulted in the fourth
quarter earnings of $831,461.
