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

    TYLER, Texas, April 21 /PRNewswire-FirstCall/ -- B. G. Hartley, Chairman
and Chief Executive Officer of Southside Bancshares, Inc. (Nasdaq: SBSI),
reported financial results for the first quarter ended March 31, 2005.
    Southside reported net income of $3,575,000 for the first quarter ended
March 31, 2005 compared to $4,495,000 for the same period in 2004. The decrease
in net income of $920,000, or 20.5%, is a direct result of a reduction in income
from the sale of available for sale securities, net of tax, of $1,342,000 when
comparing the first quarter ended March 31, 2005, to the same period in 2004.

    During the first quarter ended March 31, 2005, Southside had a loss on the
sale of available for sale securities of $216,000, or $143,000, net of tax. The
sales of securities at a loss during the first quarter 2005 allowed the Company
to restructure a portion of the securities portfolio which should provide
additional interest income in future quarters. This compares to a gain on the
sale of available for sale securities during the first quarter ended March 31,
2004, of $1,817,000, or $1,199,000, net of tax. During the year ended December
31, 2004, 65.9% of Southside's gains on the sales of available for sale
securities occurred during the first quarter ended March 31, 2004. When
comparing the first quarter ended March 31, 2005 with the same period in 2004,
net income, excluding losses or gains on sales of available for sale securities,
reflected an increase of $422,000, or 12.8%.

    Earnings per fully diluted share were $0.30 for the first quarter ended
March 31, 2005, compared to $0.37 for the same period in 2004. The loss per
share attributable to the sale of securities was $0.01 for the first quarter
ended March 31, 2005. Earnings per share attributable to the sale of securities
were $0.10 for the quarter ended March 31, 2004.

    The annualized return on average shareholders' equity for the quarter ended
March 31, 2005 was 13.81% compared to 17.25% for the same period in 2004. The
annualized return on average assets was 0.88% for the quarter ended March 31,
2005, compared to 1.26% for the same period in 2004.

    Southside anticipates opening its 29th banking center during the second
quarter of 2005, in Seven Points, approximately 60 miles west of Tyler. This
growing lake community located southeast of Dallas should provide Southside an
attractive new market area from which to expand the Company's customer base.

    Net interest income of $10.4 million for the first quarter 2005, increased
$858,000, or 9.0%, over the first quarter 2004. Average total interest earning
assets, the primary factor in net interest income growth, increased 16.0% from
the first quarter 2004, to $1.55 billion for the first quarter 2005. This more
than offset the decrease in the Company's net interest margin to 2.98% and net
interest spread to 2.50% during the first quarter ended March 31, 2005, when
compared to 3.17% and 2.75%, respectively, for the same period in 2004.



    Noninterest income, excluding losses and gains on sales of securities, was
$5.0 million for the first quarter 2005, an increase of $318,000, or 6.8%, over
the first quarter 2004. Noninterest income increased primarily due to a $244,000
special distribution received as a result of the merger of the PULSE EFT
Association with Discover Financial Services.

    Noninterest expense of $10.6 million for the first quarter 2005 increased
$488,000, or 4.8%, over the first quarter 2004, primarily as a result of
increases in salaries and employee benefits due to higher staffing levels and
salary increases.

    Provision for federal tax expense of $771,000 for the first quarter 2005,
decreased $435,000, or 36.1%, from first quarter 2004. The effective tax rate as
a percentage of pre-tax income was 17.7% for the quarter ended March 31, 2005
compared to 21.2% for the quarter ended March 31, 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.

    The Company experienced solid loan growth during the first quarter ended
March 31, 2005, as loans, net of unearned discount, increased $12.8 million from
December 31, 2004. Asset quality improved as non-performing assets decreased
$656,000, or 18.6%, to $2.9 million at March 31, 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.

    Deposits increased $30.5 million, or 3.2%, to $971.4 million during the
first quarter ended March 31, 2005. We are pleased deposits continue to grow as
a result of our expanding branch network and continued market penetration.

    During the first quarter 2005, in conjunction with the $5 million stock
repurchase plan approved by the Board of Directors, the Company purchased
233,550 shares of common stock at an average price of $21.40 per share. The
purchase of this $5.0 million of treasury stock was the primary reason for the
reduction in shareholders' equity of $6.5 million, or 6.2%, to $98.2 million at
March 31, 2005 when compared to $104.7 million at December 31, 2004. Other
factors decreasing shareholders' equity were changes in the market value of the
available for sale securities portfolio and the payment of cash dividends, all
of which are partially offset by net income.

    At March 31, 2005, assets totaled $1.66 billion compared to $1.48 billion at
March 31, 2004, an increase of $185.9 million, or 12.6%. Loans, net of unearned
discount, increased $42.5 million, or 7.2%, from $594.3 million at March 31,
2004, to $636.8 million at March 31, 2005. Investment and mortgage- backed
securities increased $115.2 million, or 15.3%, from $751.2 million at March 31,
2004, to $866.4 million at March 31, 2005. Deposits increased $85.6 million, or
9.7%, from $885.9 million at March 31, 2004, to $971.4 million at March 31,
2005. FHLB advances increased $98.4 million, or 22.3%, from $441.8 million at
March 31, 2004, to $540.3 million at March 31, 2005. Shareholders' equity
totaled $98.2 million, or 5.9%, of total assets at March 31, 2005, as compared
to $106.1 million, or 7.2%, of total assets at March 31, 2004, a decrease of
$7.9 million or 7.4%.

    Certain statements of other than historical fact that are contained in this
document and in written material, press releases and oral statements issued by
or on behalf of Southside Bancshares, Inc., (the "Company") a bank holding
company, may be considered to be "forward-looking statements" as that term is
defined in the Private Securities Litigation Reform Act of 1995. These
statements may include words such as "expect," "estimate," "project,"
"anticipate," "believe," "could," "should," "may," "intend," "probability,"
"risk," "target," "objective" and similar expressions. Forward-looking
statements are subject to significant risks and uncertainties and the Company's
actual results may differ materially from the results discussed in the
forward-looking statements. For example, certain market risk disclosures are
dependent on choices about key model characteristics and assumptions and are
subject to various limitations. By their nature, certain of the market risk
disclosures are only estimates and could be materially different from what
actually occurs in the future. As a result, actual income gains and losses could
materially differ from those that have been estimated. Other factors that could
cause actual results to differ materially from forward- looking statements
include, but are not limited to general economic conditions, either globally,
nationally or in the State of Texas, legislation or regulatory changes which
adversely affect the businesses in which the Company is engaged, adverse changes
in Government Sponsored Enterprises (the "GSE's") status or financial condition
impacting the GSE's guarantees or ability to pay or issue debt, economic or
other disruptions caused by acts of terrorism or military actions in Iraq,
Afghanistan or other areas, changes in the interest rate yield curve or interest
rate environment which reduce interest margins and may impact prepayments on the
mortgage-backed securities portfolio, changes effecting the leverage strategy,
significant increases in competition in the banking and financial services
industry, changes in consumer spending, borrowing and saving habits,
technological changes, the Company's ability to increase market share and
control expenses, the effect of changes in federal or state tax laws, the effect
of compliance with legislation or regulatory changes, the effect of changes in
accounting policies and practices and the costs and effects of unanticipated
litigation.
