16.7% ROE for 1st Quarter of 2003</b></FONT></P>


<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>FRESNO, CA, April 10, 2003
-- Dennis R. Woods, President and Chief Executive Officer of United Security
Bancshares http://www.unitedsecuritybank.com/ (NasdaqNM: UBFO) reported today
the results of operations for the first quarter of 2003. Net income was
$1,734,000, for a $219,000 increase or 14.4% above 2002. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Basic earnings per share
for the first quarter were $0.32 compared with $0.28 for 2002, a 14.3% increase.
Diluted earnings per share for the quarter were also $0.32 compared with $0.28 a
year ago. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Woods added, &#147;The
levels of non-performing assets fell by 20% from year end during the first
quarter and earnings grew by 14.4% compared with the year ago period. I&#146;m
very pleased with these accomplishments, especially because they were
accomplished in an anemic economic environment. We've also seen the price of the
Company's stock climb recently along with the daily number of shares traded. We
believe this partly has to do with expectations that the Company's stock will be
included in the Russell 2000 index, starting this July. When one strives to
build shareholder value every day, its always very rewarding to see positive
results materialize.&quot; </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>For the three months just
ended, return on average equity was 16.7% and the return on average assets was
1.36%. For the same period in 2002 both ratios were the same, ROAE was 16.7% and
ROAA was 1.36%. The stability of these key ratios is indicative of the banks'
consistent performance and ability to build shareholder value, even during
uncertain economic times. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>The 58th consecutive
quarterly cash dividend of $0.145 per share, up from $0.13 for an 11.5% increase
from a year ago, was declared on March 25, 2003 to be paid on April 23, 2003, to
shareholders of record on April 11, 2003. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Shareholders&#146; equity
ended the quarter at $41,803,000, an increase of 14.7% over March 31, 2002.
Dividends of $2.8 million were paid out of shareholders&#146; equity to
shareholders during the past 12 months and $1.01 million was utilized to
purchase and retire shares of Company stock at an average price of $17.27. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Net interest income for the
first quarter 2003 was $4.6 million, up $448 thousand from 2002 for an increase
of 10.8%. The net interest margin declined from 4.07% in 2002 to 3.89% in 2003.
The decline is primarily attributable to the decline in interest rates
administered by the Federal Reserve Bank. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Noninterest income for the
first quarter of 2003 was $1,108,000, down from $1,319,000 in 2002 for a
decrease of $211,000 or 16.1%. The decrease is primarily the result of $248,000
that was earned in shared appreciation fees in 2002 compared with only $11,000
in 2003. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>First quarter operating
expenses for the three months ended March 31 were $2,848,000 for 2003 and
$2,695,000 for 2002, an increase of $153,000 or 5.7%. The primary factors
contributing to the rise were salaries and other employee benefits and other
expense items. The efficiency ratio changed to 50.08% for 2002 from 49.45% in
2002. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>The provision for loan loss
was $245 thousand for the first quarter of 2003 and $620 thousand for 2002. The
banks model used to determine the adequacy of the allowance for loan losses is
the primary factor for establishing the amount of the provision for loan losses
and is considered adequate. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Non-performing assets
improved to 3.82% of total assets on March 31, 2003, down from 4.89% at December
31, 2002. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>United Security Bancshares
is a $510 million bank holding company. United Security Bank, it&#146;s
principal subsidiary is a state chartered bank and member of the Federal Reserve
Bank of San Francisco. </FONT></P>
