                                 FIRST AMENDMENT
                          TO SOUTHSIDE BANCSHARES CORP.
                    DEFERRED COMPENSATION PLAN FOR DIRECTORS

         This First Amendment (hereinafter referred to as the "Amendment") is
entered into this 1st day of December, 1999, the effective date, between
SOUTHSIDE BANCSHARES CORP. (the "Company"), with its principal place of business
in St. Louis, Missouri (the "Company"), and THOMAS M. TESCHNER, a director of
the Company (hereinafter referred to as the "Director").

         WHEREAS, the Director has served on the Board of Directors of the
Company (hereinafter referred to as the "Board"), and the Board wishes to
provide additional incentives for the Director's continued service; and

         WHEREAS, the Director has contributed to the success and profitability
of the Company and is expected to continue such contribution; and

         WHEREAS, the Director and the Company have previously entered into a
plan entitled Southside Bancshares Corp. Deferred Compensation Plan for
Directors, dated April 25, 1996, which includes an agreement entitled the
Southside Bancshares Corp. Deferred Compensation Plan for Directors
Participation Agreement executed by the Director (hereinafter collectively
referred to as the "Previous Plan"), which provided that the Company would
provide certain benefits to the Director upon his retirement; and

         WHEREAS, the Company and the Director desire to set forth their
Amendment to the Previous Plan as to fees the Director has already deferred and
the continued deferral of a portion of the Director's fees as a deferred
compensation plan and to provide certain additional benefits in the case of the
Director's death while serving as a Director of the Company; and

         WHEREAS, the Company and the Director desire to provide the Director,
in lieu of Director's fees already deferred and the deferral of annual
Director's fees of Sixteen Thousand Eight Hundred and 00/100 Dollars
($16,800.00) per year for the next ten (10) years, as compensation for his
services to the Company, a post-retirement income or a pre-retirement death
benefit to his beneficiary.

         NOW, THEREFORE, in consideration of the mutual agreements contained
herein, the Company and the Director hereby amend and restate the Previous Plan
as follows:

         1. Director agrees that the benefits provided under this Amendment are
in lieu of the benefits accumulated to the Director under the Previous Plan.

         2. The liability existing on the financial records on the Company
("Rollover Balance") under the Previous Plan as of the effective date of this
Amendment will be included in the Director's Account as hereinafter defined.
<PAGE>   3
         3. Director revokes all prior deferral elections and agrees to a
reduction of the current payment of his compensation for service on the Board by
Sixteen Thousand Eight Hundred and 00/100 Dollars ($16,800.00) per year,
annually deferred in twelve (12) substantially equal monthly installments, for a
period of ten (10) years, or such other amount as shall be elected by the
Director in a signed writing delivered to the Company, and to defer receipt of
such amount until paid pursuant to later provisions of this Amendment.
Compensation reductions under this Amendment shall cease at the earlier of the
end of the deferral period or when said Director attains age sixty (60). The
Director may change the amount of or suspend future deferrals with respect to
fees and retainers earned for calendar years commencing after the date of change
or suspension as he may specify by written notice to the Company. Following any
such suspension, the Director may make a new election to again become a deferral
participant; however, the election to defer shall be irrevocable for the
particular year, and must be made prior to the beginning of the calendar year.

         4. The Company will record amounts deferred pursuant to paragraphs 2
and 3 and amounts credited pursuant to paragraph 5 in a separate account
(hereinafter referred to as the "Account") in the financial records of the
Company.

         5. Until the Director attains age sixty (60), the Company will credit
interest compounded monthly to the Account as follows: subject to a minimum
annual rate of six percent (6%) and a maximum annual rate of fifteen percent
(15%), a rate equal to the annual percentage increase (the "Annual Rate") of the
stock price of Southside Bancshares Corp (the "Stock Price"). The annual
percentage increase of the Stock Price shall be initially determined utilizing a
fraction that has a numerator calculated by subtracting the closing bid price
one year prior to the effective date of this Amendment from the closing bid
price on the effective date of this Amendment and a denominator equal to the
closing bid price one year prior to the effective date of this Amendment. For
each subsequent year that this Amendment is effective, the Annual Rate will be
determined utilizing a fraction that has a numerator calculated by subtracting
the closing bid price one year prior to each anniversary of effective date of
this Amendment from the closing bid price on each anniversary of effective date
of this Amendment and a denominator equal to the closing bid price one year
prior to the anniversary of effective date of this Amendment. Notwithstanding
the above, at any time during the period the Director is scheduled to make a
deferral under paragraph 3 of this Amendment and the Director fails to defer a
monthly amount under paragraph 3 the annual interest rate the Company will
credit the Account under this paragraph will be six percent (6%), compounded
monthly for the period the Director makes no deferral. Once the Director attains
age sixty (60) or the service of the Director is terminated and payments from
the Account continue to be deferred, the Company will credit interest compounded
monthly to the Account at a rate of six percent (6%) until the balance of the
Account is fully paid.

         6. The Account will be unfunded and no assets of the Company will be
segregated with respect to the Account. Further, the Account shall be kept only
for purposes of its identification on the books and records of the Company as a
liability of the Company to the Director, and the Account will be subject to the
claims of general creditors of the Company.

         7. Amounts held in the Account or a death benefit will be payable as
indicated in Paragraph 8 upon the first to occur of the following events:


                                       2
<PAGE>   4
                  (a) termination of the Director's membership on the Board of
         the Company other than by death; or

                  (b) termination of this Agreement pursuant to Paragraph 17; or

                  (c) the occurrence of the Director's 60th birthday; or

                  (d) the death of the Director.

The Company shall only have the obligation to complete making payments under
Paragraph 8 to the Director, his/her designated beneficiary, or the estate of
the designated beneficiary pursuant to the applicable subparagraph above.

         8.
                  a. If payment is to be made due to the occurrence of an event
described in 7(a) or in 7(b), subject to provisions of paragraph 9, an amount
equal to the balance in the Account shall be paid to the Director in one lump
sum not later than sixty (60) days following the occurrence of the event.

                  b. If payment is to be made due to the occurrence of the event
described in 7(c), the balance in the Account shall be paid to the Director in
substantially equal monthly installments over a one hundred eighty (180) month
period commencing on the first day of the month following the Director's
birthday.

                  c. If payment is to be made due to the occurrence of the event
described in 7(d), the amount payable to the Director's beneficiary shall be the
monthly amount stated in Addendum A multiplied by a fraction the numerator of
which is equal to the sum of: (i) the Rollover Balance, including interest
credited to this amount through the date of the Director's death pursuant to
paragraph 5 of this Amendment; (ii) the amount actually deferred under this
Amendment until the Director's death, including the interest credited to these
deferrals through the date of the Director's death pursuant to paragraph 5 of
this Amendment; (iii) if the Director's death occurs before the ten year
deferral period set forth in paragraph 3 of this Amendment, the projected
amounts that would have been deferred from the date of the Director's death
through the date the Director would have attained age fifty-three (53), based on
the Director's elected deferral amount in effect on the date of the Director's
death; and (iv) the interest that would have been credited to the amounts in
(i), (ii), and (iii) immediately above pursuant to paragraph 5 from the date of
the Director's death until the date the Director would have reached age 60
assuming an Annual Rate that would equal the average annual interest credited to
the Director's Account from the effective date of this Amendment through the
Director's death or, if the Director was not making monthly deferrals at the
date of the Director's death and the Director's death occurred within ten (10)
years of the date of this Amendment, an Annual Rate equal to six percent (6%);
and the denominator of which shall equal the sum of the Rollover Balance and the
projected total deferral that would have occurred if the Director would have
deferred the amount set forth in paragraph 3 for the period set forth in
paragraph 3, including the maximum annual interest credited under paragraph 5 of
this Amendment to the Rollover balance and to the projected deferrals under
paragraph 3; provided, however, under no circumstances shall the monthly benefit
be greater than that stated in Addendum A. Payments to the Director's


                                       3
<PAGE>   5
designated beneficiary shall begin the first day of the month following the
month of the death of the Director.

                  d. Notwithstanding the foregoing subparagraph (c), if the
Director commits suicide and as a result of such suicide the payment of the
death proceeds is denied on any policy of insurance owned by the Company
insuring the life of the Director, the amount payable to the Director's
designated beneficiary shall be the Account balance on the date of the
Director's death less an amount equal to the sum of any monthly amounts
previously paid the designated beneficiary. Payment to the Director's designated
beneficiary shall be made in a lump sum within sixty (60) days from the denial
of payment of proceeds from any life insurance policy owned by the Company.

         9. If payment is to be made under subparagraph 7 (a) and the Director's
termination is due to disability covered under a disability insurance policy,
the Company may, in its sole discretion, defer payment until payments under the
disability policy cease.

         10. In the event the Director should die before receiving the payment
due under subparagraph 8(a) or the payments due under subparagraph 8(b), the
remaining payment or payments, as the case may be, shall be paid to the
Director's designated beneficiary.

         11. If the Director's designated beneficiary dies before receiving all
payments due, the Company shall pay the remaining payments, in the same form of
pay out as the designated beneficiary has been receiving or is to receive, to
the revocable trust of the Designated beneficiary and, if none, to the estate of
the designated beneficiary.

         12. Director may request in a signed writing delivered to the Board,
that the Company pay a hardship distribution to the Director from amounts held
in the Account. Hardship means an unforeseen event or situation that creates an
extraordinary financial need that cannot reasonably be met by other resources of
the Director. The Board shall elect in its sole discretion, without
participation of the Director making the request, whether or not to grant such
request.

         13. Any amounts payable to the Director's designated beneficiary
pursuant to this Amendment will be paid to the beneficiary designated by the
Director in a signed writing delivered to the Company. Director has the right to
change his beneficiary designation by delivering to the Company a subsequent
signed writing. If Director does not designate a beneficiary in the manner
described in this paragraph 13, or if the designated beneficiary has predeceased
the Director, then amounts payable hereunder will be payable first to the
Director's surviving spouse; and if the Director has no surviving spouse, then
such amounts will then be payable to the Director's estate or as provided by a
decree of distribution or other proper order by the court having jurisdiction of
such estate. No one other than the Director shall have any right to designate a
beneficiary.

         14. The right to receive payments under this Amendment shall not be
assigned or encumbered, or subject to anticipation, garnishment, attachment, or
any other legal process of creditors of the Director or of any designated
beneficiary. If the Director or a designated beneficiary attempts to assign such
right, the Board, in its sole discretion, may suspend, reduce or terminate any
or all rights created by this Amendment as to the Director or the designated
beneficiary attempting said assignment.


                                       4
<PAGE>   6
         15. Nothing in this Amendment shall be construed as giving the Director
the right to be retained on the Company's Board. The Director shall remain
subject to discharge at any time and to the same extent as if this Amendment had
not been executed.

         16. The Company does not assure or guarantee the tax consequences of
payments provided hereunder or matters beyond its control, and the Director
certifies that his decision to reduce and defer receipt of his compensation is
not due to any reliance upon financial, tax or legal advice given by the Company
or any of its employees.

         17. This Amendment may be amended or terminated at any time by the
Company in writing; however, no amendment or termination may reduce amounts
payable to Director or his designated beneficiary below the then Account
balance, without such person's written consent.

         18. The Board upon ninety (90) days advance written notice to the
Director may terminate this Amendment and, in the event of such termination,
shall pay an amount equal to the then Account balance in a lump sum to the
Director within sixty (60) days following such termination.

         19. While the Company intends that this Plan will result in the
deferral of the imposition of a federal income tax on the funds credited
hereunder until such time as they actually be paid to a Director, nothing herein
shall be construed as a promise, guarantee or other representation by the
Company of such tax effect nor, without limitation, shall the Company be liable
for any taxes, penalties or other amounts incurred by Directors in the event it
is determined by applicable authorities that such deferral was not accomplished,
and the Director should consult his or her own tax advisor(s) to determine the
tax consequences in his or her specific case.

         IN WITNESS WHEREOF, the parties hereof have entered into this Amendment
at St. Louis, Missouri, as of the date first above written.
