          SOUTHSIDE BANCSHARES, INC. ANNOUNCES SECOND QUARTER EARNINGS;
                     NASDAQ NATIONAL MARKET SYMBOL - 'SBSI'

    TYLER, Texas, Aug. 2 /PRNewswire-FirstCall/ -- B. G. Hartley, Chairman and
Chief Executive Officer of Southside Bancshares, Inc. (Nasdaq: SBSI), reported
financial results for the second quarter ended June 30, 2005.

    For the second quarter ended June 30, 2005 Southside reported net income
increased $26,000, or 0.7%, to $3,697,000, compared to $3,671,000 for the same
period in 2004. Earnings per fully diluted share were $0.30 for both the second
quarters ended June 30, 2005 and 2004.

    Southside reported net income of $7,272,000 for the six months ended
June 30, 2005. The decrease in net income of $894,000, or 10.9%, is a direct
result of a reduction in income from the sale of available for sale securities,
net of tax, of $1.4 million when comparing the six months ended June 30, 2005,
to the same period in 2004. When comparing the six months ended June 30, 2005
with the same period in 2004, net income, excluding losses or gains on sales of
available for sale securities, reflected an increase of $512,000, or 7.5%.
Earnings per fully diluted share were $0.60 for the six months ended June 30,
2005, compared to $0.67 for the same period in 2004, a decrease of $0.07, or
10.4%. Earnings per fully diluted share attributable to the sale of securities
were $0.11 for the six months ended June 30, 2004 compared to zero for the same
period in 2005.

    During the six months ended June 30, 2005, Southside had a loss on the sale
of available for sale securities of $56,000, or $37,000, net of tax. The sales
of securities at a loss during the six months ended June 30, 2005 allowed the
Company to restructure a portion of the securities portfolio which may provide
additional interest income in future quarters. This compares to a gain on the
sale of available for sale securities during the six months ended June 30, 2004,
of $2.1 million, or $1.4 million, net of tax. During the year ended December 31,
2004, 75.2% of Southside's gains on the sales of available for sale securities
occurred during the six months ended June 30, 2004.

    The annualized return on average shareholders' equity for the six months
ended June 30, 2005 was 14.10% compared to 15.83% for the same period in 2004.
The annualized return on average assets was 0.88% for the six months ended June
30, 2005, compared to 1.12% for the same period in 2004.

    The Company continued to experience solid loan growth during the six months
ended June 30, 2005, as loans, net of unearned discount, increased $35.2 million
or 5.6% from December 31, 2004. Loan growth during 2005 was actually stronger
than reported due to the sale of $6.2 million of student loans during the second
quarter ended June 30, 2005. Asset quality improved as non-performing assets
decreased $964,000, or 27.4%, to $2.6 million at June 30, 2005 when compared to
$3.5 million at December 31, 2004. We believe that the Company's asset quality
ratios as reported in this earnings release remain sound.



    During the second quarter the Company hired a loan executive to assist in an
expanded regional lending effort. He joins the Company from one of the largest
banks in the country and has over 20 years of experience lending in East Texas
and surrounding regions. With his assistance, the Company plans to expand the
regions in which it lends. The Company looks forward to the possibility that its
loan growth may begin to accelerate in the future as the Company develops
strategies to expand its lending territory.

    Deposits exceeded $1.0 billion for the first time in the Company's history,
as deposits increased $65.3 million, or 6.9%, to $1.0 billion at June 30, 2005
when compared to December 31, 2004. We are pleased deposits continue to grow at
an excellent pace as a result of our expanding branch network and continued
market penetration.

    During the second quarter Southside opened its 29th banking center at Seven
Points approximately 60 miles west of Tyler. This growing lake community located
southeast of Dallas should provide an attractive new market area from which to
expand the Company's customer base. Southside anticipates opening its 30th
banking center during the last half of 2005, in Palestine, approximately 50
miles southwest of Tyler. The addition of the City of Palestine should
complement and enhance Southside's southern expansion efforts which already
includes banking centers in Jacksonville and Bullard.

    Net interest income of $10.2 million for the second quarter 2005, increased
$771,000, or 8.2%, over the second quarter 2004. Average total interest earning
assets, the primary factor in net interest income growth, increased $151.1
million, or 10.8% from the second quarter 2004, to $1.5 billion for the second
quarter 2005. This more than offset the decrease in the Company's net interest
margin to 2.90% and net interest spread to 2.38% during the second quarter ended
June 30, 2005, when compared to 2.98% and 2.54%, respectively, for the same
period in 2004.

    Noninterest income, excluding gains on sales of securities, was
$5.5 million for the second quarter 2005, an increase of $464,000, or 9.3%, over
the second quarter 2004.

    Noninterest expense of $11.1 million for the second quarter 2005 increased
$1.2 million, or 12.3%, over the second quarter 2004, primarily as a result of
increases in salaries and employee benefits due to higher staffing levels,
salary increases and increases in retirement expense.

    The decrease to net income during the six months ended June 30, 2005, when
compared to the same period in 2004 was primarily attributable to a decrease in
gains on available for sale securities of $2.1 million, or 102.7% and an
increase in noninterest expense of $1.7 million, or 8.5%. The decrease in net
income for the six months ended June 30, 2005, when compared to the same period
in 2004, was partially offset by an increase in net interest income of $1.6
million, or 8.6%, an increase in noninterest income, excluding security gains,
of $782,000, or 8.1%, and a decrease in the provision for loan losses of
$63,000, or 12.0% and a decrease in federal income tax expense of $459,000, or
22.4%.

    Provision for federal tax expense of $822,000 for the second quarter 2005,
decreased $24,000, or 2.8%, from second quarter 2004. The effective tax rate as
a percentage of pre-tax income was 18.2% for the quarter ended June 30, 2005
compared to 18.7% for the quarter ended June 30, 2004. The decrease in the
effective tax rate and income tax expense was due to the decrease in taxable
income as a percentage of total income.

habits, technological changes, the Company's ability to increase market share
