  SOUTHSIDE BANCSHARES, INC. ANNOUNCES AN INCREASE IN FOURTH QUARTER AND ANNUAL
                                    EARNINGS

    TYLER, Texas, Jan. 25 /PRNewswire-FirstCall/ -- Southside Bancshares, Inc.
(Nasdaq: SBSI) ("Southside" or the "Company") reports financial results for
the three months and year ended December 31, 2006.

    Net income increased 19.8%, or $692,000 for the three months ended December
31, 2006, to $4.2 million from $3.5 million for the same period in 2005. For the
year ended December 31, 2006, net income increased $410,000, or 2.8% to $15.0
million when compared to $14.6 million for the same period in 2005.

    B. G. Hartley, Chairman and Chief Executive Officer, stated, "Southside had
an excellent and especially gratifying year during 2006. Our success in
achieving these results was due to the significant progress we made on a number
of previously discussed key initiatives, intended to increase revenues and
contain costs. The success of the initiatives more than offset the additional
operating expenses associated with opening four de novo branches since September
30, 2005, and the increasingly challenging interest rate environment experienced
during 2006."

    Earnings per fully diluted share increased 22.2%, or $0.06 and 2.6%, or
$0.03 for the three months and year ended December 31, 2006, to $0.33 and $1.18,
respectively, when compared to $0.27 and $1.15 for the same periods in 2005.

    The return on average shareholders' equity for the three months and year
ended December 31, 2006 were 14.11% and 13.48%, respectively, compared to 13.05%
and 13.88%, respectively, for the same periods in 2005. The annual return on
average assets were 0.88% and 0.81%, respectively, for the three months and year
ended December 31, 2006, compared to 0.79% and 0.86%, respectively, for the same
periods in 2005.

    Loan and Deposit Growth

    The Company continued to experience solid loan growth during the three
months ended December 31, 2006, as loans increased $17.6 million, or 2.4%, to
$759.1 million from $741.5 million at September 30, 2006. During the year ended
December 31, 2006, Southside experienced strong loan growth as loans increased
$78.8 million, or 11.6%, to $759.1 million from $680.4 million at December 31,
2005. Loan growth during 2006 has occurred primarily in commercial loans, 1-4
family residential loans, and commercial real estate loans. The consistent
growth in loans is significant given the increasing competition in the Texas
banking markets we serve. Additionally, the 2006 loan growth was accompanied by
a 31.0% decrease in nonperforming assets.

    Commenting on the loan growth, B. G. Hartley said, "Our marketplace in Texas
has continued to expand over the past several years through the opening of
branches in strategic market areas. Positioning for future success, with de novo
branching a key element, remains a central part of our business strategy. In
addition to the loan and deposit growth, another critical portion of Southside's
business strategy is the focus on increasing the number of accounts and
relationships. Continued growth in the number of deposit accounts should provide
Southside significant opportunities to enhance fee income. Our goal is to become
the primary financial provider for these account holders, thereby creating value
from within by utilizing this additional organic growth source.

    During the three months ended December 31, 2006, deposits increased $71.6
million, or 5.9%, to $1.28 billion from $1.21 billion at September 30, 2006.
During the year ended December 31, 2006, the Company's deposits increased $171.7
million, or 15.5% to $1.28 billion from $1.11 billion at December 31, 2005.
Approximately $68.0 million of the overall growth in deposits during 2006
resulted from our expanding branch network and continued market penetration.
Price related competition for deposits has intensified. While the Company has
attempted to maintain a disciplined deposit pricing strategy, the current
competitive environment could pressure the net interest margin in the coming
quarters. The remaining $103.7 million of the deposit growth was the result of
the Company issuing callable-brokered certificates of deposits with long-term
maturities where the Company controls numerous call options. Brokered deposits
at December 31, 2006 totaled $123.5 million compared to $19.8 million at
December 31, 2005. We believe these callable-brokered CDs offer the Company
significant long-term flexibility.



    Net Interest Income

    Net interest income decreased $81,000, or 0.8% to $10.2 million for the
three months ended December 31, 2006, when compared to $10.3 million for the
same period in 2005. The net interest margin and net interest spread were
impacted by the significant increase in short-term interest rates during 2005
and 2006 combined with significantly smaller increases in long-term interest
rates. This resulted in an inverted yield curve, where short-term interest rates
were higher than long-term interest rates. As a result, the Company's net
interest margin and net interest spread decreased to 2.45% and 1.65%,
respectively, for the three months ended December 31, 2006 compared to 2.72% and
2.13%, respectively, for the same period in 2005 and 2.51% and 1.75%,
respectively, for the three months ended September 30, 2006. Should the yield
curve remain inverted or invert more, the Company's net interest margin and
spread could come under additional pressure during 2007.

    Net Income for the Three Months

    The increase in net income for the three months ended December 31, 2006 was
primarily attributable to an increase in noninterest income and a decrease in
provision for loan losses. Noninterest income, excluding gain on sale of
available for sale securities, increased $721,000, or 13.7%, for the three
months ended December 31, 2006, compared to the same period in 2005. The
increases in noninterest income were primarily results of increases in deposit
services income, trust income, gain on sale of loans, and other income.
Provision for loan losses decreased $391,000, or 75.8%, for the three months
ended December 31, 2006, compared to the same period in 2005.

    Partially offsetting the increase in net income, Federal income tax expense
increased $497,000, or 63.8%, for the three months ended December 31, 2006, when
compared to the same period in 2005. Federal income tax expense increased as a
result of the decrease in tax-exempt income as a percentage of pre-tax income
for the three months ended December 31, 2006, when compared to the same period
in 2005.

    Net Income for the Year

    The increase in net income for the year ended December 31, 2006 was
primarily attributable to an increase in net interest income, noninterest income
and a decrease in provision for loan losses. Net interest income increased
$409,000, or 1.0%, for the year ended December 31, 2006 when compared to the
same period in 2005. Net interest income increased as a result of increases in
the Company's average interest earning assets during the year ended December 31,
2006 when compared to the same period in 2005, which more than offset the
decrease in the Company's net interest spread and margin during the same period.
Noninterest income, excluding gain on sale of available for sale securities,
increased $1.7 million, or 8.2%, for the year ended December 31, 2006, when
compared to the same period in 2005. The increases in noninterest income were
primarily results of increases in deposit services income, trust income, and
other income. Gain on sale of securities available for sale increased $515,000,
or 225.9%, for the year ended December 31, 2006 compared to the same period in
2005. Provision for loan losses decreased $383,000, or 26.2%, for the year ended
December 31, 2006, compared to the same period in 2005.



    The following items partially offset the increase in net income for the year
ended December 31, 2006, when compared to the same period in 2005. Noninterest
expense increased $1.8 million, or 4.2%, for the year ended December 31, 2006,
compared to the same period in 2005. Noninterest expense increased primarily as
a result of increases in salary and employee benefits, occupancy expense, and
ATM expense. Salaries and employee benefits increased $796,000, or 2.9%, during
the year ended December 31, 2006, when compared to the same period in 2005, due
to normal salary increases and higher staffing levels associated with the
Company's continued branch expansion and regional lending initiative. Occupancy
expense increased $520,000, or 12.2%, ATM expense increased $307,000, or 47.4%,
and Federal income tax expense increased $807,000, or 24.5%, for the year ended
December 31, 2006, when compared to the same period in 2005. Occupancy expense
increased primarily due to branch expansion and Federal income tax expense
increased as a result of the decrease in tax-exempt income as a percentage of
pre-tax income for the year ended December 31, 2006 when compared to the same
period in 2005.
