         In addition, pursuant to the Mississippi Business Corporation Act,
directors and officers are entitled to indemnification in certain events as
summarized below:

Section  79-4-8.50.  SUBARTICLE DEFINITIONS.

         In this subarticle:

                 (1)      "Corporation" includes any domestic or foreign
         predecessor entity of a corporation in a merger or other transaction
         in which the predecessor's existence ceased upon consummation of the
         transaction.

                 (2)      "Director" means an individual who is or was a
         director of a corporation or an individual who, while a director of a
         corporation, is or was serving at the corporation's request as a
         director, officer, partner, trustee, employee or agent of another
         foreign or domestic corporation, partnership, joint venture, trust,
         employee benefit plan or other enterprise.  A director is considered
         to be serving an employee benefit plan at the corporation's request if
         his duties to the corporation also impose duties on, or otherwise
         involve services by, him to the plan or to participants in or
         beneficiaries of the plan.  "Director" includes, unless the context
         requires otherwise, the estate or personal representative of a
         director.

                 (3)      "Expenses" include counsel fees.

                 (4)      "Liability" means the obligation to pay a judgment,
         settlement, penalty, fine (including an excise tax assessed with
         respect to an employee benefit plan), or reasonable expenses incurred
         with respect to a proceeding.

                 (5)      "Official capacity" means:  (i) when used with
         respect to a director, the office of director in a corporation; and
         (ii) when used with respect to an individual other than a director as
         contemplated in Section  79-4-8.56, the office in a corporation held
         by the officer or the employment or agency relationship undertaken by
         the employee or agent on behalf of the corporation.  "Official
         capacity" does not include service for any other foreign or domestic
         corporation or any partnership, joint venture, trust, employee benefit
         plan or other enterprise.





                                       3
<PAGE>   4
                 (6)      "Party" includes an individual who was, is, or is
         threatened to be made a named defendant or respondent in a proceeding.

                 (7)      "Proceeding" means any threatened, pending, or
         completed action, suit or proceeding, whether civil, criminal,
         administrative or investigative and whether formal or informal.

Section  79-4-8.51.       AUTHORITY TO INDEMNIFY.

         (a)     Except as provided in subsection (d), a corporation may
                 indemnify an individual made a party to a proceeding because
                 he is or was a director against liability incurred in the
                 proceeding if:

                 (1)      He conducted himself in good faith; and

                 (2)      He reasonably believed:

                          (i)     In the case of conduct in his official
                 capacity with the corporation, that his conduct was in its
                 best interest; and

                          (ii)    In all other cases, that his conduct was at
                 least not opposed to its best interests; and

                 (3)      In the case of any criminal proceeding, he had no
                 reasonable cause to believe his conduct was unlawful.

         (b)     A director's conduct with respect to an employee benefit plan
         for a purpose he reasonably believed to be in the interest of the
         participants in and beneficiaries of the plan is conduct that
         satisfies the requirement of subsection (a)(2)(ii).

         (c)     The termination of a proceeding by judgment, order,
         settlement, conviction or upon a plea of nolo contendere or its
         equivalent is not, of itself, determinative that the director did not
         meet the standard of conduct described in this section.

         (d)     A corporation may not indemnify a director under this section:

                 (1)      In connection with a proceeding by or in the right of
                 the corporation in which the director was adjudged liable to
                 the corporation; or

                 (2)      In connection with any other proceeding charging
                 improper personal benefit to him, whether or not involving
                 action in his official capacity, in which he was adjudged
                 liable on the basis that personal benefit was improperly
                 received by him.

         (e)     Indemnification permitted under this section in connection
         with a proceeding by or in the right of the corporation is limited to
         reasonable expenses incurred in connection with the proceeding.

Section  79-4-8.52.  MANDATORY INDEMNIFICATION.

         Unless limited by its articles of incorporation, a corporation shall
indemnify a director who was wholly successful, on the merits or otherwise, in
the defense of any proceeding to which he was a party because he is or was a
director of the corporation against reasonable expenses incurred by him in
connection with the proceeding.

Section  79-4-8.53.  ADVANCE FOR EXPENSES.

         (a)     A corporation may pay for or reimburse the reasonable expenses





                                       4
<PAGE>   5
incurred by a director who is a party to a proceeding in advance of final
disposition of the proceeding if:

                 (1)      The director furnishes the corporation a written
                 affirmation of his good faith belief that he has met the
                 standard of conduct described in Section  79-4-8.51;

                 (2)      The director furnishes the corporation a written
                 undertaking, executed personally or on his behalf, to repay
                 the advance if it is ultimately determined that he did not
                 meet the standard of conduct; and

                 (3)      A determination is made that the facts then known to
                 those making the determination would not preclude
                 indemnification under this subarticle.

         (b)     The undertaking required by subsection (a)(2) must be an
unlimited general obligation of the director but need not be secured and may be
accepted without reference to financial ability to make repayment.

         (c)     Determinations and authorizations of payments under this
section shall be made in the manner specified in Section  79-4-8.55.

Section  79-4-8.54.  COURT ORDERED INDEMNIFICATION.

         Unless a corporation's articles of incorporation provide otherwise, a
director of the corporation who is a party to a proceeding may apply for
indemnification to the court conducting the proceeding or to another court of
competent jurisdiction.  On receipt of an application, the court after giving
any notice the court considers necessary may order indemnification if it
determines:

                 (1)      The director is entitled to mandatory indemnification
                 under Section  79-4-8.52, in which case the court shall also
                 order the corporation to pay the director's reasonable
                 expenses incurred to obtain court-ordered indemnification; or

                 (2)      The director is fairly and reasonably entitled to
                 indemnification in view of all the relevant circumstances,
                 whether or not he met the standard of conduct set forth in
                 Section  79-4-8.51 or was adjudged liable as described in
                 Section  79-4-8.51(d), but if he was adjudged so liable his
                 indemnification is limited to reasonable expenses incurred.

Section  79-4-8.55.  DETERMINATION AND AUTHORIZATION OF INDEMNIFICATION.

         (a)     A corporation may not indemnify a director under Section
79-4-8.51 unless authorized in the specific case after a determination has been
made that indemnification of the director is permissible in the circumstances
because he has met the standard of conduct set forth in Section  79-4-8.51.

         (b)     The determination shall be made:

                 (1)      By the board of directors by majority vote of a
                 quorum consisting of directors not at the time parties to the
                 proceeding;

                 (2)      If a quorum cannot be obtained under subdivision (1),
                 by majority vote of a committee duly designated by the board
                 of directors (in which designation directors who are parties
                 may participate), consisting solely of two (2) or more
                 directors not at the time parties to the proceeding;

                 (3)      By special legal counsel:





                                       5
<PAGE>   6
                                  (i)      Selected by the board of directors
                          of its committee in the manner prescribed in
                          subdivision (1) or (2); or

                                  (ii)     If a quorum of the board of
                          directors cannot be obtained under subdivision (1)
                          and a committee cannot be designated under
                          subdivision (2), selected by a majority vote of the
                          full board of directors (in which selection directors
                          who are parties may participate); or

                 (4)      By the shareholders, but shares owned by or voted
                 under the control of directors who are at the time parties to
                 the proceeding may not be voted on the determination.

         (c)     Authorization of indemnification and evaluation as to
reasonableness of expenses shall be made in the same manner as the
determination that indemnification is permissible, except that if the
determination is made by special legal counsel, authorization of
indemnification and evaluation as to reasonableness of expenses shall be made
by those entitled under subsection (b)(3) to select counsel.

Section  79-4-8.56.  INDEMNIFICATION OF OFFICERS, EMPLOYEES AND AGENTS.

         Unless a corporation's articles of incorporation provide otherwise:

         (1)     An officer of the corporation who is not a director is
entitled to mandatory indemnification under Section  79-4-8.52, and is entitled
to apply for court-ordered indemnification under Section  79-4-8.54, in each
case to the same extent as a director;

         (2)     The corporation may indemnify and advance expenses under this
subarticle to an officer, employee or agent of the corporation who is not a
director to the same extent as to a director; and

         (3)     A corporation may also indemnify and advance expenses to an
officer, employee or agent who is not a director to the extent, consistent with
public policy, that may be provided by its articles of incorporation, bylaws,
general or specific action of its board of directors or contract.

Section  79-4-8.57.  INSURANCE.

         A corporation may purchase and maintain insurance on behalf of an
individual who is or was a director, officer, employee or agent of the
corporation, or who, while a director, officer, employee or agent of the
corporation, is or was serving at the request of the corporation as a director,
officer, partner, trustee, employee or agent of another foreign or domestic
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise against liability asserted against or incurred by him in that
capacity or arising from his status as a director, officer, employee or agent,
whether or not the corporation would have power to indemnify him against the
same liability under Section  79-4- 8.51 or 79-4-8.52.

Section  79-4-8.58.  APPLICATION OF ARTICLE.

         (a)     Unless the articles of incorporation or bylaws provide
otherwise, any authorization of indemnification in the articles of
incorporation or bylaws shall not be deemed to prevent the corporation from
providing the indemnification permitted or mandated by this subarticle.

         (b)     Any corporation shall have power to make any further
indemnity, including advance of expenses, to and to enter contracts of
indemnity with any director, officer, employee or agent that may be authorized
by the articles of





                                       6
<PAGE>   7
incorporation or any bylaw made by the shareholders or any resolution adopted,
before or after the event, by the shareholders, except an indemnity against his
gross negligence or willful misconduct.  Unless the articles of incorporation,
or any such bylaws or resolution provide otherwise, any determination as to any
further indemnity shall be made in accordance with subsection (b) of Section

Item 9.  Undertakings.

(a)      The undersigned Registrant hereby undertakes:

         (1)  To file, during any period in which offers or sales are being
         made, a post-effective amendment to this Registration Statement:

          (i)      To include any prospectus required by Section 10(a) (3) of
         the Securities Act of 1933;

          (ii)     To reflect in the prospectus any facts or events arising
         after the effective date of this Registration Statement (or the most
         recent post-effective amendment thereof) which, individually or in the
         aggregate, represents a fundamental change in the information set
         forth in this Registration Statement;

          (iii)    To include any material information with respect to the plan
         of distribution not previously disclosed in this Registration
         Statement or any material change to such information in this
         Registration Statement;

         Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the Registration Statement is on Form S-3 or Form S-8 and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the Registration Statement.

         (2)       That, for the purpose of determining any liability under the
Securities Act of 1933, each such post- effective amendment shall be deemed to
be a new Registration Statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona





                                       7

fide offering thereof.

         (3)       To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

(b)      The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to section 15(d) of the Securities Exchange Act
of 1934) that is incorporated by reference in this Registration Statement shall
be deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

(c)      Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers, and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is unenforceable.  In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer, or
controlling person connected with the securities being registered) the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

                                  INTRODUCTION

         Effective January 1, 1964, First National Bank of Jackson, whose name
has since been changed to Trustmark National Bank, and which bank is
hereinafter referred to as "Sponsor," adopted a retirement plan to provide
retirement benefits for its eligible Employees.  Thereafter, in order to comply
with the Employee Retirement Income Security Act of 1974, and to effect certain
changes in the Plan, the Sponsor amended, restated and continued the Plan
effective January 1, 1976.  The plan was amended, restated and continued again,
effective January 1, 1984, to comply with the Tax Equity and Fiscal
Responsibility Act of 1982, the Deficit Reduction Act of 1984 and the
Retirement Equity Act of 1984.  Following that amendment, restatement and
continuation, the Plan has further been amended from time to time.

         Now, in order to comply with changes in the law caused by the Tax
Reform Act of 1986, the Omnibus Budget Reconciliation Act of 1986, the Omnibus
Budget Reconciliation Act of 1987, the Technical and Miscellaneous Revenue Act
of 1988, the Omnibus Budget Reconciliation Act of 1989, the Unemployment
Compensation Amendments of 1992, the Omnibus Budget Reconciliation Act of 1993,
and various regulations, the Sponsor hereby amends, restates and continues the
Plan effective January 1, 1989 (except as otherwise indicated herein for
specified provisions or as required by applicable law or regulations).

         The Plan and incorporated Trust shall continue to be designated as the
Trustmark National Bank Profit Sharing Plan.  The Plan is adopted as an
amendment to, and restatement of, the Trustmark National Bank Profit Sharing
Plan, as it was in effect on the day preceding the effective date of adoption
of this amendment.

         The purposes of the Plan are to provide the Employees who qualify to
participate in the Plan and their Beneficiaries certain benefits as stipulated
herein in the event of retirement, death or termination of Service prior to
retirement, and to provide such Employees the opportunity to save for such
events on a tax-deferred incentive basis pursuant to the provisions of section
401(k) of the Code.  The Plan is intended to be qualified under section 401(a)
of the Code as a profit sharing plan and its incorporated Trust is intended to
qualify as a tax-exempt trust under section 501(a) of the Code.

         Unless specifically otherwise provided in the Plan, the provisions of
the restated Plan shall apply only to Employees who have Service with the
Employer on or after January 1, 1989.  The rights and benefits, if any, of
former Employees shall be determined in accordance with the provisions of the
Plan as in effect on the respective dates of termination of Service of such
former Employees.

                                  DEFINITIONS



                 The following terms when used herein, unless the context
                 clearly indicates otherwise, shall have the meanings set forth
                 hereinafter.

1.01     "ACCOUNT" shall mean the Employer Account and the Personal Account
         maintained on behalf of a Participant.

1.02     "ADOPTING EMPLOYER" shall mean any business organization or
         corporation affiliated with the Sponsor through complete or partial
         ownership by the Sponsor or by any owner therein, or  which is
         otherwise cooperating with the Sponsor for purposes of establishing
         and maintaining a qualified plan, which is authorized by the Board of
         Directors of the Sponsor to adopt the Plan, and which subsequently
         adopts the Plan.

         The term shall also include any business organization or corporation
         into which the Adopting Employer may be merged or consolidated or by
         which it may be succeeded.

1.03     "ALLOCATION DATE" shall mean December 31 of each Plan Year, or such
         other date as of which assets are valued for purposes of an interim
         allocation pursuant to the provisions of Section 4.07 hereof.
         Effective January 1, 1995, Allocation Date shall mean June 30 and
         December 31 of each Plan Year, or such other date as of which assets
         are valued for purposes of an interim allocation pursuant to the
         provisions of Section 4.07 hereof.

1.04     "ANNUITY STARTING DATE" shall mean the first day of the first period
         for which an amount is paid as an annuity or any other form.

1.05     "ANNUITY TRANSFER PLAN" shall mean, with respect to a Participant, a
         defined benefit pension plan, a money purchase pension plan, a target
         benefit pension plan, a stock bonus plan, or another profit sharing
         plan which provided for an annuity normal form of benefit payment to
         such Participant and which transfers to this Plan, on or after the
         first day of the Plan Year beginning after December 31, 1984, assets
         which are attributable to benefits for the Participant.

1.06     "BENEFICIARY" shall mean the person, persons or legal entity last
         designated in accordance with Section 7.04 hereof, who shall receive
         any death benefits that may be payable under the Plan after the death
         of a Participant or Retired Participant.

1.07     "BREAK IN SERVICE" shall mean a consecutive twelve (12) month period
         during which the Employee does not perform more than five hundred
         (500) Hours of Service. For purposes of determining eligibility to
         participate in the Plan, pursuant to Article 2 hereof, the initial
         twelve (12) month period shall commence on the date the Employee first





                                     1 - 1
<PAGE>   8
         performs an Hour of Service, and each subsequent twelve (12) month
         period shall be the Plan Year, beginning with the Plan Year which
         commences prior to the end of the initial twelve (12) month period.
         For purposes of determining Vesting Service, the consecutive twelve
         (12) month period shall be the Plan Year.

         For purposes of determining whether a Break in Service has occurred,
         Hours of Service shall include any period in which the Employee is
         absent from work for maternity or paternity reasons for any of the
         following:

         (a)     by reason of the pregnancy of the Employee,

         (b)     by reason of the birth of a child of the Employee,

         (c)     by reason of the placement of a child with the Employee in
                 connection with the adoption of such child by such Employee,
                 or

         (d)     for purposes of caring for such child for a period beginning
                 immediately following such birth or placement.

         Provided, however, that Hours of Service credited for such absence
         from work shall not exceed the Hours which would normally have been
         credited to such individual but for such absence.  Such Hours of
         Service shall be credited in the Plan Year in which the absence from
         work begins if an Employee would be prevented from incurring a Break
         in Service in such Plan Year solely because the period of absence is
         treated as Hours of Service or, in any other case, in the immediately
         following Plan Year.  No credit for Hours of Service for absence by
         reason of such pregnancy or placement shall be given hereunder unless
         an Employee furnishes to the Committee such timely information as the
         Plan Administrator may reasonably require to establish that the
         absence from work is for a reason set forth in (a) through (d).

1.08     "CODE" shall mean the Internal Revenue Code of 1986, as amended from
         time to time, and as in effect on the relevant date to be interpreted
         hereunder.

1.09     "COMMITTEE" shall mean the committee as provided in Article 9 hereof
         appointed with respect to the administration of the Plan.

1.10     "COMPENSATION" shall mean, except as otherwise provided herein,
         compensation which is paid to the Employee by the Employer, as defined
         in (a) or (b) below, subject to (c), (d) and (e) below.

         (a)     Compensation means wages pursuant to Code section 3401(a) and
                 all other payments of compensation to an Employee by his
                 Employer (in the course of the Employer's trade or business)
                 for which the Employer is required to furnish the Employee a
                 written statement under Code Sections 6041(d), 6051(a)(3), and
                 6052.  Compensation shall be determined without regard to any
                 rules under Code section 3401(a) that limit the remuneration
                 included in wages based on the nature or location of the





                                     1 - 2
<PAGE>   9
                 employment or the services performed.  However, compensation
                 shall exclude amounts paid or reimbursed by the employer for
                 moving expenses, automobile allowance, imputed income from
                 excess group term life insurance and severance pay.  Only
                 Compensation for the portion of any Plan Year during which an
                 Employee is a Participant shall be taken into account for
                 purposes of the Plan.

         (b)     For purposes of Section 1.21 and Sections 3.03 and 3.04
                 hereof, Compensation shall mean the total compensation for
                 Service by an Employee for the Employer that is includable in
                 gross income as provided in Section 414(s) of the Code for the
                 period during the Plan Year in which he is a Participant or
                 for the entire Plan Year, as determined by the Plan
                 Administrator.

         (c)     Compensation shall include any contributions made by the
                 Employer on behalf of an Employee to a plan qualified under
                 section 125 or section 401(k) of the Code, but shall not
                 include any other contribution made by the Employer under this
                 Plan or under any pension plan or other employee benefit plan
                 or insurance plan maintained by the Employer for the benefit
                 of such Employee.

         (d)     For any Plan Year beginning after December 31, 1988 and before
                 January 1, 1994, the annual compensation of each Participant
                 taken into account for determining all benefits provided under
                 the Plan for any such year shall not exceed two hundred
                 thousand dollars ($200,000).  This limitation shall be
                 adjusted by the Secretary at the same time and in the same
                 manner as under section 415(d) of the Code, except that the
                 dollar increase on January 1 of any calendar year is effective
                 for years beginning in such calendar year and the first
                 adjustment to the two hundred thousand dollar ($200,000)
                 limitation is effective on January 1, 1990.  In determining
                 the compensation of a Participant for purposes of this
                 limitation, the rules of section 414(q)(6) of the Code shall
                 apply, except in applying such rules, the term "family" shall
                 include only the spouse of the Participant and any lineal
                 descendants of the Participant who have not attained age
                 nineteen (19) before the close of the year.  If, as a result
                 of the application of such rules, the adjusted two hundred
                 thousand dollars ($200,000) limitation is exceeded, then
                 (except for purposes of determining the portion of
                 compensation up to the integration level if this plan provides
                 for permitted disparity), the limitation shall be prorated
                 among the affected individuals in proportion to each such
                 individual's compensation as determined under this section
                 prior to the application of this limitation.  The application
                 of this provision shall be subject to such rules as may be
                 prescribed by the Secretary of the Treasury.

         (e)     Section 401(a)(17) Limitation.  In addition to other
                 applicable limitations set forth in the Plan, and
                 notwithstanding any other provision of the Plan to the
                 contrary, for Plan Years beginning on or after January 1,
                 1994, the annual compensation of each Employee taken into
                 account under the Plan shall not exceed the OBRA '93 annual
                 compensation limit.  The OBRA '93 annual compensation limit is
                 one hundred fifty thousand dollars ($150,000), as adjusted by
                 the Commissioner for increases in the cost of living in
                 accordance with section 401(a)(17)(B) of the Code.  The
                 cost-of-





                                     1 - 3
<PAGE>   10
                 living adjustment in effect for a calendar year applies to any
                 period, not exceeding twelve (12) months, over which
                 compensation is determined (determination period) beginning in
                 such calendar year.  If a determination period consists of
                 fewer than twelve (12) months, the OBRA '93 annual
                 compensation limit will be multiplied by a fraction, the
                 numerator of which is the number of months in the
                 determination period, and the denominator of which is twelve
                 (12).

                 For Plan Years beginning on or after January 1, 1994, any
                 reference in this Plan to the limitation under section
                 401(a)(17) of the Code shall mean the OBRA '93 annual
                 compensation limit set forth in this provision.

                 If compensation for any prior determination period is taken
                 into account in determining an Employee's benefits accruing in
                 the current plan year, the compensation for that prior
                 determination period is subject to the OBRA '93 annual
                 compensation limit in effect for that prior determination
                 period.  For this purpose, for determination periods beginning
                 before the first day of the first Plan Year beginning on or
                 after January 1, 1994, the OBRA '93 annual compensation limit
                 is one hundred fifty thousand dollars ($150,000).

1.11     "CONTROLLED GROUP" shall mean, except as modified by section 415(h) of
         the Code for purposes of determining limitations under section 415 of
         the Code pursuant to Section 4.04 hereof, any corporation which is a
         member of a controlled group of corporations (as defined by section
         414(b) of the Code) of which the Employer is a member, any other trade
         or business (whether or not incorporated) which is under common
         control (as defined by section 414(c) of the Code) with respect to the
         Employer or any organization which is a member of an affiliated
         service group (as defined by section 414(m) of the Code) of which the
         Employer is a member and any other entity required to be aggregated
         with the Employer pursuant to regulations under section 414(o) of the
         Code, but only for the period during which such other corporation,
         trade or business or organization and the Employer are members of such
         controlled group of corporations, are under such common control or are
         serving as members of such an affiliated service group.  All employees
         of members of a Controlled Group shall be treated as employed by a
         single employer for purposes of determining compliance with sections
         401, 410, 411, 415 and 416 of the Code.

1.12     "DISABILITY" shall mean a physical or mental condition which totally
         and permanently prevents the Participant from engaging in his usual
         occupation or employment for remuneration or profit, except for the
         purpose of rehabilitation not incompatible with a finding of total and
         permanent disability.  The determination by the Committee as to
         whether a Participant is totally and permanently disabled shall be
         made on the basis of medical evidence by a licensed physician
         designated by the Committee.

1.13     "EFFECTIVE DATE" shall mean January 1, 1964, the date the Plan was
         established; provided, however, that the term shall mean, for an
         Employee, the effective date of adoption of the Plan by his Employer
         if such date is later than January 1, 1964.





                                     1 - 4
<PAGE>   11
         The effective date of this amendment, restatement and continuation of
         the Plan shall be January 1, 1989, except as otherwise specifically

         would be receiving such remuneration except for an authorized Leave of
         Absence), or (b) a Leased Employee.

1.15     "EMPLOYER" shall mean the Sponsor or an Adopting Employer, or both, as
         required by the context of this Plan; provided, however, that if an
         Employee is simultaneously employed by the Sponsor and one (1) or more

1.21     "HIGHLY COMPENSATED EMPLOYEE" shall mean a person who is either a
         "highly compensated active employee" as defined in subsection (a)
         hereof or a "highly compensated former employee" as defined in
         subsection (b) hereof.

         (a)     A "highly compensated active employee" is any employee who
                 performs service for the Employer during the determination
                 year and who, during the look-back year:

                 (1)      received compensation from the Employer in excess of
                          seventy-five thousand dollars ($75,000) (as adjusted
                          pursuant to section 415(d) of the Code);

                 (2)      received compensation from the Employer in excess of
                          fifty thousand dollars ($50,000) (as adjusted
                          pursuant to section 415(d) of the Code) and was a
                          member of the top-paid group for such year; or

                 (3)      was an officer of the Employer and received
                          compensation during such year that is greater than
                          fifty percent (50%) of the dollar limitation in
                          effect under section 415(b)(1)(A) of the Code.  The
                          term "highly compensated active employee" also
                          includes:

                 (4)      An employee (i) who is described in the preceding
                          sentence if the term "determination year" is
                          substituted for the term "look-back year" and (ii)
                          who is one of the one hundred (100) employees who
                          received the most compensation from the Employer
                          during the determination year; and

                 (5)      An employee who is a five percent (5%) owner at any
                          time during the look-back year or the determination
                          year.

                 If no officer has satisfied the compensation requirement of
                 (3) above during either a determination year or look-back
                 year, the highest paid officer for such year shall be treated
                 as a Highly Compensated Employee.

         (b)     A "highly compensated former employee" is any employee who
                 separated from service (or was deemed to have separated) prior
                 to the determination year, performs no service for the
                 Employer during the determination year, and was a highly
                 compensated active employee for either the separation year or
                 any determination year ending on or after the employee's
                 fifty-fifth (55th) birthday.

         For purposes of this Section, the determination year would normally be
         the Plan Year, and the look-back year would normally be the twelve
         (12)-month period immediately preceding the determination year.
         However, the Plan Administrator has elected to make the calendar year
         calculation, provided in Section 1.414(q)-1T, Q&A 14(b), of the
         Treasury Regulations, with respect to the Plan for all Plan Years.
         Pursuant to this election and for this purpose, both the determination
         year and the look-back year are the Plan Year.

         If an employee is, during a determination year or look-back year, a
         family member of either a five percent (5%) owner who is an active or
         former employee or a Highly Compensated Employee who is one of the ten
         (10) most highly compensated employees ranked on the basis of
         compensation paid by the Employer during such year, then the family
         member and five percent (5%) owner or top ten (10) Highly Compensated
         Employee shall be treated as a single employee receiving compensation
         and Plan contributions or benefits equal to the sum of such
         compensation and contributions or benefits of the family member and
         five (5%) percent owner or top ten (10) Highly Compensated Employee.
         For purposes of this section, family member includes the spouse,
         lineal ascendants and descendants of the employee or former employee
         and the spouses of such lineal ascendants and descendants.

         In determining who is a Highly Compensated Employee, employees who are
         non-resident aliens and who received no earned income (within the
         meaning of Code section 911(d)(2)) from the Employer constituting
         United States source income within the meaning of Code section
         861(a)(3) shall not be treated as Employees.  Additionally, all
         employers in the Controlled Group shall be taken into account as a
         single employer and Leased Employees shall be considered employees
         unless such Leased Employees are covered by a plan described in Code
         section 414(n)(5) and are not covered in any qualified plan maintained
         by the Employer.  The exclusion of Leased Employees for this purpose
         shall be applied on a uniform and consistent basis for all of the
         Employer's retirement plans.  Highly Compensated Former Employees
         shall be treated as Highly Compensated Employees without regard to
         whether they performed services during the determination year.

         The determination of who is a Highly Compensated Employee, including
         but not limited to the determinations of the number and identity of
         Employees in the top-paid group, the top one hundred (100) Employees,
         the number of Employees treated as officers and the compensation that
         is considered, will be made in accordance with Section 414(q) of the
         Code and the regulations thereunder.  Such determination may also take
         into account other rulings and pronouncements issued by the Secretary
         of the Treasury or the Internal Revenue Service.

1.22     "HOURS OF SERVICE" shall mean the aggregate of the following:

         (a)     Hours of Service shall include each actual hour for which an
                 Employee is paid, or entitled to payment, for the performance
                 of duties for the Employer.  These hours shall be credited to
                 the Employee for the Plan Year in which the duties are
                 performed.

         (b)     Hours of Service shall include each hour for which an Employee
                 is paid, or entitled to payment, by the Employer on account of
                 a period of time during which no duties are performed
                 (irrespective of whether the employment relationship has
                 terminated) due to vacation, holiday, illness, incapacity
                 (including disability), layoff, jury duty, military duty or
                 authorized leave of absence.  No more than five hundred and
                 one (501) Hours of Service shall be credited under this
                 subsection for any single continuous period (whether or not
                 such period occurs in a single Plan Year).  Hours under this
                 subsection shall be calculated and credited pursuant to
                 Section 2530.200b-2 of the Department of Labor Regulations,
                 which are incorporated herein by this reference as if fully
                 set forth.

         (c)     Hours of Service shall include each hour for which back pay,
                 irrespective of mitigation of damages, has been either awarded
                 or agreed to by the Employer.  These hours shall be credited
                 to the Employee for the Plan Year to which the award or
                 agreement pertains rather than the Plan Year in which the
                 award, agreement or payment is made.  Hours shall not be
                 credited under both this and either of the two (2) preceding
                 subsections of this section.

         (d)     Hours of Service, however, shall not be credited for payments
                 made solely to comply with workers' or unemployment
                 compensation or disability insurance laws or as reimbursement
                 for medical expenses.

         Hours of Service shall be credited for employment with other members
         of a Controlled Group of which the Employer is a member.  Hours of
         Service shall also be credited for any individual considered an
         Employee for purposes of the Plan under section 414(n) of the Code or
         section 414(o) of the Code and the regulations thereunder.

1.23     "INCOME" shall mean the net gain or loss of the Trust Fund from
         investments, as reflected by interest payments, dividends, realized
         and unrealized gains and losses on securities, other investment
         transactions, and expenses paid from the Trust Fund which are not
         reimbursed by the Employer.  In determining the Income of the Trust
         Fund for any period, assets shall be valued on the basis of fair
         market value.

         If any portion of the Trust Fund is segregated into one (1) or more
         separate accounts on behalf of a Participant, Income shall be
         determined with respect to each such account.

1.24     "INVESTMENT MANAGER" shall mean any Fiduciary, other than the Trustee,
         who

         (a)     has the power to manage, acquire, or dispose of any asset of

         employee of the Employer, who provides services for the Employer if
         the following conditions are met:

                 the Employer and a leasing organization,

                 business field of the Employer, by employees.

         Notwithstanding the foregoing, a Leased Employee shall not be

                 providing:

                 (1)      a nonintegrated employer contribution rate of at

                          in section 415(c)(3) of the Code, but including
                          amounts contributed pursuant to a salary reduction

         services performed for the Employer shall be treated as provided by
         the Employer.

1.26     "LEAVE OF ABSENCE" shall mean any unpaid absence authorized by the
         Employer under the Employer's standard personnel practices; provided

         of conscription in time of peace; and if, further, the Employee
         returns to Service within the period during which his employment
         rights are protected by law.  Individuals on Leave of Absence shall be
         treated under the Plan as if they were Employees according to the
         terms hereof.  Failure to return to Service with the Employer by the
         date on which a Leave of Absence expires shall be considered to be a

                 the computation of Vesting Service, the Employee's employment
                 in an excluded classification of employees of the Employer.

         In no event shall Service include any period of time during which the
         Employee was not a common-law employee, but rather a partner or a
         proprietor or an independent contractor.

1.38     "SPONSOR" shall mean Trustmark National Bank, a National Banking
         Association with principal offices in Jackson, Mississippi,  and any

1.39     "SPOUSE" shall mean the actual spouse or surviving spouse of a
         Participant or a former spouse of a Participant, if and to the extent
         such former spouse is to be treated as a spouse or surviving spouse of
         the Participant under a qualified domestic relations order described
         in section 414(p) of the Code.

1.40     "TRUST" shall mean the trust continued pursuant to Article 10 hereof
         by the Sponsor under which the Employer contributions and any
         contributions by Participants shall be received, held, invested and
         disbursed by the Trustee to, or for the benefit of, Participants,
         Retired Participants and their Beneficiaries.

1.41     "TRUST FUND" OR "FUND" shall mean any and all cash, securities, real
         estate and other property held by the Trustee pursuant to the terms of
         the Plan.

1.42     "TRUSTEE" shall mean Trustmark National Bank or any individual,
         individuals or financial institution as shall have accepted the
         appointment by the Sponsor as successor Trustee under the Plan.

1.43     "VESTING SERVICE" shall mean for an Employee his period of Service for
         purposes of determining his vested percentage, and shall equal the
         number of Plan Years during which the Employee completes at least one
         thousand (1,000) Hours of Service.  Provided, however, that Service
         during any period for which the Employer did not maintain the Plan or
         a predecessor plan of which this Plan is a continuation, shall be
         disregarded.

1.44     "YEAR OF SERVICE" shall mean the Service of an Employee that is
         credited for purposes of determining eligibility to participate in the
         Plan and shall equal the number of twelve (12) consecutive month
         periods during which an Employee completes at least one thousand
         (1,000) Hours of Service.  The initial twelve (12) consecutive month
         period shall commence on the date the Employee first performs an Hour
         of Service, and each subsequent twelve (12) month period shall be the
         Plan Year, beginning with the Plan Year which commences prior to the
         end of the initial twelve (12) month period.

         For purposes of this Section only, an Employee who first performs an
         Hour of Service on the first working day of a Plan Year shall be
         considered to have first performed an Hour of Service on the first day
         of that Plan Year.

                           PARTICIPATION IN THE PLAN

2.01     ELIGIBILITY DATE.

         Each Employee on December 31, 1988, who is a Participant in the Plan
         on that date and who continues to be an Employee on January 1, 1989,
         shall without further requirements, continue as a Participant
         hereunder.

         Each other Employee on January 1, 1989, and each person who becomes an
         Employee after January 1, 1989, shall, subject to the overriding
         provisions of the following paragraphs, be eligible to become a
         Participant on the first Entry Date coincident with or next following
         the date such person completes one (1) Year of Service, provided he is
         still an Employee on such Entry Date.

         Provided, however, that no Employee shall become a Participant prior
         to the effective date of adoption of the Plan by the Employee's
         Employer.

         Notwithstanding the above, the following classes of Employees shall be
         considered as excluded classes for purposes of the Plan, and Employees
         who are members of such classes shall not be eligible to participate
         in the plan:

         (a)     Employees who are active participants in the Trustmark
                 National Bank Pension Plan who were also participants in the
                 Canton Exchange Bank Employees Retirement Plan prior to its
                 merger into the Trustmark National Bank Pension Plan;

         (b)     Employees who are active participants in the Rankin County 
                 Bank 401K plan;

         (c)     Leased Employees.

2.02     ELIGIBILITY DETERMINATION.

         Within a reasonable time prior to the date on which an Employee will
         become eligible, if the Employee continues employment with the
         Employer, to participate in the Plan, the Plan Administrator shall
         forward to the Employee a salary deferral agreement and such
         application for participation as the Plan Administrator shall require
         and shall notify him of the requirements to become a Participant.
         Should any question arise as to eligibility, the Plan Administrator
         shall decide such question, and such determination, if made in good
         faith and in accordance with the terms of the Plan, shall be final.





                                     2 - 1
<PAGE>   20
2.03     PARTICIPATION.

         An Employee shall become a Participant on the first day on which he is
         eligible to become a Participant and has filed with the Plan
         Administrator such written application as the Plan Administrator may
         require for participation in the Plan, in which the Employee has
         agreed to abide by all the provisions hereof and has specified the
         amount of the Employee's salary deferral, if any, pursuant to Section
         3.02 hereof.

         Once an Employee has become a Participant he shall continue to be a
         Participant until his Service terminates or he dies, sustains
         Disability, incurs a Break in Service or retires.  In the event that a
         Participant's Service terminates or he dies, sustains Disability, or
         retires in accordance with the provisions of the Plan, he shall
         thereupon cease to be a Participant.  A Participant who ceases to be
         eligible for the Plan because of a change in his classification of
         employment shall not be entitled to receive benefits solely by reason
         of such change in classification, but rather his eligibility for
         benefits shall be determined in accordance with the provisions of the
         Plan; provided, however, that employment of the Participant in such an
         excluded class shall be deemed Service for participation and vesting
         purposes.

2.04     PARTICIPATION FOLLOWING REEMPLOYMENT OR BREAK IN SERVICE.

         Except as otherwise provided in the following sentence, a former
         Participant whose Service has terminated or who has incurred a Break
         in Service, shall be eligible to participate immediately upon again
         being credited with Service.  Such an individual who is re-employed in
         an excluded class of employees, as described in Section 2.01, shall
         not be eligible to participate while in such excluded class.

         Employees who were formerly participants in the Rankin County Bank
         401K Plan but who ceased to be participants in such plan due to
         termination of employment, and who have since been re-employed, shall
         not be eligible to re-enter the Rankin County Bank 401K Plan but shall
         be eligible to participate in this Plan immediately upon their
         re-employment date.

2.05     PARTICIPATION FOLLOWING CHANGE IN CLASSIFICATION.

         In the event a Participant becomes ineligible to participate because
         he is no longer a member of an eligible class of Employees, but his
         Service has not terminated, such Employee shall be eligible to
         participate immediately upon his return to an eligible class of
         Employees.  If such participant's Service is terminated, his
         eligibility to participate shall be determined as a former Participant
         pursuant to Section 2.04 hereof.

         In the event an Employee who is not a member of the eligible class of
         Employees becomes a member of the eligible class, such Employee then
         shall participate immediately if such Employee has satisfied the
         minimum age and Service requirements and would have previously become
         eligible to participate had he been in the eligible class.  If such an
         Employee has not satisfied the minimum age and Service requirements





                                     2 - 2
<PAGE>   21
         when he becomes a member of the eligible class, he shall participate
         as provided in Section 2.03 hereof, and his employment in the excluded
         class shall be treated as Service in determining his eligibility to
         participate.

2.06     FAMILY AND MEDICAL LEAVE ACT REQUIREMENTS.

         Notwithstanding any other provisions of the Plan, in the case of an
         Employee who takes family or medical leave as an eligible employee of
         a covered employer under the provisions of the Family and Medical
         Leave Act of 1993 (FMLA), any period of FMLA leave shall be treated as
         continued service for purposes of eligibility to participate and
         Vesting Service to the extent required by applicable law.

                           CONTRIBUTIONS TO THE PLAN


3.01     EMPLOYER CONTRIBUTIONS.

         Each Plan Year ending after the Effective Date and during the
         continuance of the Plan, the Employer may, at its discretion, make
         contributions to the Plan as described below.

         (a)     Employer Basic Contribution - The Employer may contribute a
                 basic contribution on behalf of Participants entitled to share
                 in the allocation of such contribution, pursuant to Section
                 4.01(a) hereof.  Such basic contribution shall be subject to
                 the vesting schedule provided in Section 8.01 hereof and shall
                 be credited to Part I of the Participant's Employer Account.

         (b)     Employer Matching Contribution - The Employer may contribute
                 on behalf of each Participant an amount equal to a matching
                 percentage of all or a portion of such Participant's salary
                 deferral contributions during a payroll period.  For any Plan
                 Year in which the Employer decides to make an Employer
                 matching contribution, the Committee shall designate in
                 writing both the matching percentage and the portion of salary
                 deferral contributions to be matched.  Provided, however, the
                 Employer shall not contribute amounts which (i) would, if
                 allocated to the Employer Account of Highly Compensated
                 Employees pursuant to Section 4.01(b), create excess aggregate
                 contributions (as defined in Section 3.04) or (ii) are
                 attributable to contributions which pursuant to Sections
                 3.02(a), 3.03 or 3.04 are to be distributed to Employees.  The
                 Employer matching contribution shall be subject to the vesting
                 schedule provided in Section 8.01 hereof and shall be credited
                 to Part II of the Participant's Employer Account.

         (c)     Qualified Matching Contribution - The Employer may, in order
                 to preserve the qualified status of the Plan, contribute a
                 Qualified Matching Contribution based on the salary deferral
                 contributions of Non- highly Compensated Employees.  Qualified
                 Matching Contributions shall be fully vested at all times,
                 shall be subject to the distribution provisions that are
                 applicable to salary deferral contributions and shall be
                 credited to Part III of the Participant's Employer Account.

         Employer contributions shall be made as soon as practicable on or
         before the due date (including extensions) for filing the federal
         income tax return for the year for which such contributions are made.

         In satisfaction of its contribution obligations under this Section
         3.01, the Employer may, at its option, deliver or cause to be
         delivered either cash or such other property as is acceptable to the
         Trustee.

<PAGE>   23
         Contributions made to the Plan by the Employer shall be made on the
         condition that they are deductible under section 404 of the Code.

3.02     CONTRIBUTIONS BY, OR ON BEHALF OF, PARTICIPANTS.

         A Participant may elect contributions to the Plan, as described below.
         Such amounts shall be fully vested at all times.

         (a)     Salary Deferral Contributions.  Effective with any payroll
                 period beginning on or after the date on which he becomes a
                 Participant, a Participant may voluntarily elect to enter into
                 a salary deferral agreement with the Employer.  Such salary
                 deferral agreement shall serve to direct the Employer to
                 contribute to the Participant's Personal Account, as salary
                 deferral contributions, a portion of the amount which would
                 otherwise be paid to the Participant as direct Compensation.
                 Salary deferral contributions shall be subject to the
                 following restrictions:

                 (1)      the amount of such contributions for any single pay
                          period may not exceed two hundred eight dollars and
                          thirty-three cents ($208.33) or fifteen percent of
                          Compensation for the pay period, whichever is less;

                 (2)      the amount of such contributions for any Plan Year
                          may not exceed five thousand dollars;

                 (3)      if the Participant elects to make salary deferral
                          contributions, such election must result in salary
                          deferral contributions of at least ten dollars ($10)
                          per pay period.

                 Provided, further, that such amount shall be subject also to
                 the limitations on annual additions for the limitation year
                 under Section 4.04 hereof.

                 A Participant's aggregate elective salary deferral
                 contributions in any taxable year of the Participant shall not
                 be greater than seven thousand dollars ($7,000), or such
                 increased amount pursuant to section 402(g) of the Code for
                 any taxable year as determined by the Commissioner of Internal
                 Revenue and effective on January 1 of the taxable year.
                 Elective salary deferral contributions in excess of the
                 preceding limit occurring in any Plan Year (together with any
                 Income allocable to such amount, if required by law or
                 regulations to be distributed) shall be distributed not later
                 than the first April 15th following the close of the Plan Year
                 in which such excess deferral contributions occurred, to the
                 Participant on whose behalf the excess was contributed.

                 If the Participant makes "elective deferrals," as defined in
                 regulations issued pursuant to section 402(g) of the Code, to
                 more than one plan, which exceed the limit described above in
                 the aggregate, such Participant may elect a distribution of a
                 part or all of such excess amount which has been contributed
                 to this Plan.  An election to receive a distribution of such
                 excess deferrals must be in writing and must include the
                 Employee's certification that the specified amount is an
                 excess deferral.  Such election must be made not later than
                 the first March 15th following the close of the Plan Year





                                     3 - 2
<PAGE>   24
                 in which such excess deferrals occurred.  Upon such election,
                 the excess amount specified by the Participant shall be
                 distributed to the Participant not later than the first April
                 15th following the close of the Plan Year in which such excess
                 deferrals occurred.  The amount of such excess to be
                 distributed shall be reduced by the amount of any excess
                 contributions previously distributed pursuant to Section 3.03
                 hereof for the Plan Year beginning within the taxable year for
                 which the excess under this Section 3.02 is distributed.

                 Such excess deferrals shall, if required by law or
                 regulations, be adjusted for any Income allocable to such
                 excess deferrals up to the date of distribution.  The Income
                 allocable to such excess deferrals shall be equal to the sum
                 of (i) Income allocable to Part I of the Participant's
                 Personal Account for the taxable year multiplied by a
                 fraction, the numerator of which is the excess deferrals for
                 the Participant for the year and the denominator of which is
                 the total account balance of the Employee attributable to
                 elective salary deferrals without regard to any Income
                 occurring during the taxable year; and (ii) the Income
                 allocable to Part I of the Participant's Personal Account for
                 the period between the end of the taxable year and the
                 distribution date multiplied by a fraction determined under
                 the method described in (i) of this sentence.

                 The determination of whether a Participant's elective
                 deferrals with respect to any taxable year shall exceed the
                 limitations of Code section 402(g) shall be the sole
                 responsibility of the Participant, and neither the Employer,
                 the Committee nor the Trustee shall have any obligations with
                 respect to such determination.

                 Salary deferral contributions shall be made by payroll
                 deduction and shall be considered to be salary deferral
                 contributions for the Plan Year in which they are actually
                 made.

                 The direction and agreement by the Participant to defer a
                 portion of his Compensation as a salary deferral contribution
                 rather than receive it as a cash benefit shall be in the form
                 of a salary deferral agreement as set forth in Section 2.03
                 hereof.  A Participant's salary deferral agreement may be
                 prospectively amended to change the percentage of the salary
                 deferral, either increasing, decreasing, starting or stopping
                 the percentage of salary deferral, as of any payroll period.
                 Such change shall be effective as of the first pay period
                 following receipt by the Committee of written notice of the
                 change, provided such written notice is received in time to
                 allow normal processing of the paperwork involved in
                 instituting the change.  The Committee may establish
                 additional procedures for the renewal, amendment, termination,
                 or revocation of salary deferral agreements which shall be
                 uniform and nondiscriminatory.  Provided, however, that the
                 requirement of uniformity (but not nondiscrimination) may be
                 suspended, and such differences in procedure (provided such
                 differences are merely procedural) may be permitted between
                 Highly Compensated Employees and Non-highly Compensated
                 Employees as are necessary, proper and convenient in order to
                 bring the Plan into compliance with the coverage and
                 discrimination requirements of Section 3.03 and thereby
                 preserve, or assure the preservation of, the qualified status
                 of

                 the Plan.  As a condition precedent for accepting a
                 Participant's salary deferral agreement, the Employer also
                 may, at any time, as of any time, and from time to time,
                 amend, terminate or revoke the salary deferral agreement of a
                 Participant who is a Highly Compensated Employee in order to
                 comply with the coverage and discrimination requirements of
                 Section 3.03 hereof.

                 The Employer shall contribute to Part I of the Personal
                 Account of each Participant an amount equal to the reduction
                 in such Participant's Compensation pursuant to his salary
                 deferral agreement.  The contribution to be made as a result
                 of such reduction in Compensation shall be paid to the Trustee
                 as soon as practicable, but no later than the month following
                 the month for which the reduction in Compensation was made;
                 provided, that if a Participant has executed a salary deferral
                 agreement pending the adoption of the Plan by the Employer or
                 pending a determination by the Committee whether contributions
                 on his behalf under such agreement would cause the Plan not to
                 qualify under section 401(k) of the Code, such contributions
                 may be paid to the Trustee during the month following the
                 month in which such adoption or determination is made,
                 whichever is applicable, but in no event later than thirty
                 (30) days after the end of the Plan Year.  Such salary
                 deferral contributions shall be considered to be Employer
                 contributions under the Plan and shall be nonforfeitable when
                 made.

                 If the Committee shall determine that the salary deferral
                 contributions provided for in this Section 3.02 would exceed
                 the limitations of Section 3.03 hereof, the Committee shall,
                 before the end of the Plan Year following the Plan Year during
                 which such excess contribution occurs, distribute the amount
                 of such excess to the Participant on whose behalf the
                 contribution was made.

         (b)     Voluntary After-Tax Contributions.  Voluntary after-tax
                 contributions may not be made to the Plan.  In the past, such
                 contributions were permitted, and any such amounts still in
                 the Plan shall be maintained in Part II of the Participant's
                 Personal Account.

         (c)     Rollover Contributions.  Rollover contributions by a
                 Participant (or by an Employee expected to become a
                 Participant) to his Personal Account in cash or in other
                 property acceptable to the Trustee shall be allowed from
                 individual retirement accounts, within the meaning of section
                 408(a) of the Code, which have been established as conduits
                 for other qualified plan distributions pursuant to section 402
                 or section 403 of the Code or from another qualified plan;
                 provided that no portion of any such rollover is attributable
                 to nondeductible employee contributions and provided further
                 that acceptance of such rollover contributions shall be
                 subject to any procedures governing acceptance of such
                 rollover contributions which may be established by the Plan
                 Administrator or Trustee.  Direct rollover of an eligible
                 rollover contribution as described in Code sections 401(a)(31)
                 and 402 and regulations thereunder elected by a Participant
                 (or by an Employee expected to become a Participant) shall be
                 allowed from another qualified plan, provided that such direct
                 rollover shall be made only in





                                     3 - 4
<PAGE>   26
                 cash or its equivalent  in cash or in other property
                 acceptable to the Trustee  and provided further that
                 acceptance of such rollover contributions shall be subject to
                 any procedures governing acceptance of such rollover
                 contributions which may be established by the Plan
                 Administrator or Trustee.

                 Any such rollover contributions shall be remitted to the
                 Trustee as soon as practicable, shall be credited to Part III
                 of the Participant's Personal Account and shall be fully
                 vested at all times.  Rollover contributions shall be treated
                 in the same manner as Participant voluntary after-tax
                 contributions for purposes of investment and allocation of
                 Income, and shall be withdrawable from the Participant's
                 Personal Account to the extent provided in Article 5 or
                 otherwise shall be distributed as provided in Articles 6, 7
                 and 8 hereof.

                 Rollover contributions shall not be considered (i) as
                 contributions by the Employer under Section 3.01 of this Plan,
                 (ii) in determining the maximum benefits permissible under the
                 Plan pursuant to Section 4.04 hereof or (iii) in determining
                 the Top Heavy Ratio in Section 13.02(j) hereof.

3.03     COVERAGE AND DISCRIMINATION REQUIREMENTS.

         Salary deferral contributions for any Plan Year after December 31,
         1986 shall satisfy one (1) of the following tests:

         (a)     the average deferral percentage for the Highly Compensated
                 Employees who are eligible to participate in the Plan for the
                 Plan Year shall not be more than the average deferral
                 percentage of the Non-highly Compensated Employees who are
                 eligible to participate in the Plan for the Plan Year
                 multiplied by one and twenty-five hundredths (1.25); or

         (b)     the excess of the average deferral percentage for the Highly
                 Compensated Employees who are eligible to participate in the
                 Plan for the Plan Year over that of the Non-highly Compensated
                 Employees who are eligible to participate in the Plan for the
                 Plan Year shall not be more than two percent (2%), nor shall
                 the average deferral percentage for such Highly Compensated
                 Employees be more than that of such Non-highly Compensated
                 Employees multiplied by two (2).

         For purposes of this Section, the term "average deferral percentage"
         for a group of Employees shall mean the average of the percentages,
         calculated separately for each Employee in the group, of the amount of
         salary deferral contributions and, if applicable, Qualified Matching
         Contributions, made on behalf of the Employee for a Plan Year, to the
         amount of the Employee's Compensation for such Plan Year (the
         "deferral percentage").  However, for purposes of determining the
         deferral percentage of a Participant who is a five percent (5%) owner
         of the Employer or one of the top ten (10) highest paid Highly
         Compensated Employees, the amount of contributions and Compensation of
         such Participant shall include the contributions and Compensation of
         family members (as described in Code section 414(q)(6)(B)) to the
         extent required by





                                     3 - 5
<PAGE>   27
         regulations.  Family members who are required to be aggregated with
         respect to such Highly Compensated Employees shall be disregarded as
         separate Employees in determining the average deferral percentage both
         for eligible Employees who are Highly Compensated Employees and for
         eligible Employees who are Non-highly Compensated Employees.

         A salary deferral contribution shall be considered to have been made
         with respect to a Plan Year if it (i) is allocated to the account of a
         Participant as of any date within that Plan Year and (ii) relates to
         Compensation that either would have been received by the Participant
         in the Plan Year but for the Participant's election to defer under the
         arrangement, or is attributable to services performed by the
         Participant in the Plan Year and, but for the Participant's election
         to defer, would have been received by the Participant within two and
         one- half (2-1/2) months after the close of the Plan Year.  A
         contribution shall be considered allocated as of any date within a
         Plan Year if the following conditions are met:

         (c)     such allocation is not dependent upon participation in the
                 Plan as of any date subsequent to the allocation date,

         (d)     the Employer contributions in addition to those attributable
                 to salary deferral contributions are actually made to the Plan
                 no later than the end of the period described in Code section
                 404(a)(6) applicable to the taxable year with or within which
                 the Plan Year ends, and

         (e)     the Employer contributions attributable to salary deferrals
                 are actually made to the Plan no later than the end of the
                 twelve (12) month period immediately following the end of the
                 Plan Year to which the contribution relates.

         Excess contributions shall mean, with respect to any Plan Year, the
         excess of:

         (f)     The aggregate amount of contributions actually taken into
                 account in computing the average deferral percentage of Highly
                 Compensated Employees for such Plan Year as described above,
                 over

         (g)     The maximum amount of such contributions permitted by the
                 average deferral percentage test (determined by reducing
                 contributions made on behalf of Highly Compensated Employees
                 in order of the average deferral percentages, beginning with
                 the highest of such percentages).

         Provided, that the amount of any such excess contributions to be
         distributed pursuant to this Section 3.03 with respect to a
         Participant for a Plan Year shall be reduced by any salary deferral
         contributions in excess of the dollar limit specified in Section
         3.02(a) hereof which are previously distributed to such Participant
         for his taxable year ending with or within such Plan Year.  In
         addition, the amount of such excess contribution of a Highly
         Compensated Employee whose average deferral percentage is determined
         under the family aggregation rules, shall be allocated among the
         family members in proportion





                                     3 - 6
<PAGE>   28
         to the salary deferral contributions of each family member that are
         combined to determine the combined average deferral percentage.

         Excess contributions shall, if required by law or regulations, be
         adjusted for any Income up to the date of distribution.  The Income
         allocable to such excess contribution shall be equal to the sum of (i)
         the allocable Income for the Plan Year and (ii) the allocable Income
         for the period between the end of the Plan Year and the date of
         distribution.  The Income allocable to excess contributions for such
         periods is determined in a manner analogous to the above allocation of
         Income to excess deferrals, but basing the allocation on excess
         contributions and the Income allocable to salary deferral
         contributions.

         If, for any Plan Year, salary deferral contributions are made with
         respect to the Highly Compensated Employees in excess of that
         permissible under subsections (a) and (b) of this Section 3.03, the
         Committee shall, before the end of the Plan Year following the Plan
         Year during which such excess contribution occurs, distribute the
         amount of such excess to the Participant on whose behalf the
         contribution was made.

         Any distributions made hereunder shall be made to Highly Compensated
         Employees on the basis of the respective portions of the excess
         contributions attributable to each of such Employees.

         The tests described in this Section and the corrective measures for
         insuring passage of such tests may be performed in any manner
         permitted under section 401(k) of the Code, the regulations thereunder
         and any other related rulings or pronouncements issued by the
         Secretary of the Treasury or the Internal Revenue Service.

3.04     DISCRIMINATION REQUIREMENTS FOR OTHER CONTRIBUTIONS.

         The Plan must satisfy the nondiscrimination requirements of section
         401(m) of the Code and the regulations issued thereunder, which are
         incorporated herein by reference.  The Plan shall satisfy such
         requirements if, with respect to any Plan Year, either of the
         following alternative conditions are met:

         (a)     the average contribution percentage for eligible Highly
                 Compensated Employees is not greater than the average
                 contribution percentage for eligible Non-highly Compensated
                 Employees, multiplied by one and twenty-five hundredths
                 (1.25).

         (b)     the excess of the average contribution percentage for eligible
                 Highly Compensated Employees over that of eligible Non-highly
                 Compensated Employees is not more than two percent (2%), nor
                 is the average contribution percentage for such Highly
                 Compensated Employees more than that of such Non-highly
                 Compensated Employees, multiplied by two (2).

         "Eligible Employee" shall mean any Employee who is eligible to make
         voluntary after-tax contributions, or a salary deferral contribution
         (if the Employer takes such contributions into account in the
         calculation of the average contribution percentage).  The





                                     3 - 7
<PAGE>   29
         term "average contribution percentage" for a group of Employees shall
         mean the average of the ratios, calculated separately for each
         Employee in the group, of the amount of voluntary after-tax
         contributions and Employer matching contributions made on behalf of an
         Employee during the Plan Year to that Employee's Compensation for such
         Plan Year (the "contribution percentage").  Provided, that the
         Employer may elect to include salary deferral contributions and
         Qualified Matching Contributions to the extent such contributions are
         not included in the calculation of the tests specified in Section 3.03
         hereof, in the calculation of an average contribution percentage.
         However, for purposes of determining the contribution percentage of a
         Participant who is a five percent (5%) owner of the Employer or one of
         the top ten (10) highest paid Highly Compensated Employees, the amount
         of voluntary after-tax contributions, Employer matching contributions
         and Compensation of such Participant shall include the voluntary
         after-tax contributions, Employer matching contributions and
         Compensation of family members (as described in Code section
         414(q)(6)(B)).  Family members, with respect to Highly Compensated
         Employees, shall be disregarded as separate Employees in determining
         the contribution percentage both for eligible Employees who are
         Non-highly Compensated Employees and for eligible Employees who are
         Highly Compensated Employees.

         "Excess aggregate contributions", plus any Income allocable thereto,
         shall be forfeited, if forfeitable, or if not forfeitable, distributed
         no later than the last day of each Plan Year to Participants to whose
         accounts such excess aggregate contributions were allocated for the
         preceding Plan Year.  Excess aggregate contributions shall be
         allocated to Participants who are subject to the family member
         aggregation rules of section 414(q)(6) of the Code in proportion to
         the Employee matching contributions of each family member that are
         combined to determine the combined average contribution percentage.
         Excess aggregate contributions shall be treated as annual additions,
         as defined in Section 4.04, hereof.

         "Excess aggregate contributions" shall mean, with respect to any Plan 
         Year, the excess of:

         (c)     The aggregate contribution percentage amounts taken into
                 account in computing the numerator of the contribution
                 percentage actually made on behalf of Highly Compensated
                 Employees for such Plan Year, over

         (d)     The maximum contribution percentage amounts permitted by the
                 average contribution percentage test (determined by reducing
                 contributions made on behalf of Highly Compensated Employees
                 in order of their contribution percentages beginning with the
                 highest of such percentages).

         Such determination shall be made after first determining excess
         elective deferrals pursuant to Section 3.02 and then determining
         excess contributions pursuant to Section 3.03 hereof.

         Excess aggregate contributions shall, if required by law or
         regulations, be adjusted for any Income up to the date of
         distribution.  The Income allocable to excess aggregate contributions
         for such period is determined in a manner analogous to the above
         allocation of Income to excess deferrals, but basing the allocation on
         excess aggregate contributions





                                     3 - 8
<PAGE>   30
         and the Income allocable to Employer matching contributions and
         Employee voluntary after-tax contributions.

         Forfeitures of excess aggregate contributions shall be applied to
         reduce Employer contributions.

         The tests described in this Section and the corrective measures for
         insuring passage of such tests may be performed in any manner
         permitted under section 401(m) of the Code, the regulations thereunder
         and any other related rulings or pronouncements issued by the
         Secretary of the Treasury or the Internal Revenue Service.

3.05     MULTIPLE USE OF ALTERNATIVE LIMITATION.

         Compliance with Section 3.03 and Section 3.04 shall not be achieved by
         the use of both the limitation in Section 3.03(b) and the limitation
         in Section 3.04(b) for the same Plan Year.  The determination and
         correction of such a multiple use shall be governed by the rules set
         forth in section 401(m) of the Code and in regulations, rulings or
         other pronouncements interpreting such section, which are incorporated
         herein by reference; provided, however, that the multiple use shall be
         corrected through reduction of the average contribution percentage of
         all Highly Compensated Employees.

3.06     MEDIUM OF FINANCING THE PLAN.

         Investment of all contributions made in accordance with the Plan and
         provision for payment of benefits to Retired Participants and
         Beneficiaries shall be accomplished by a Trust, as it may be amended
         from time to time, which shall constitute a part of the Plan.

                     ALLOCATIONS TO PARTICIPANTS' ACCOUNTS


4.01     ALLOCATION OF EMPLOYER CONTRIBUTIONS.

         Employer contributions shall be allocated as follows:

         (a)     Employer Basic Contributions and Forfeitures.  Any Employer
                 basic contributions made pursuant to Section 3.01(a) hereof
                 and Forfeitures becoming available during the Plan Year shall
                 be allocated on the last Allocation Date of the Plan Year to
                 Part I of the Employer Account of each Participant entitled to
                 share in such contributions and Forfeitures.  Only those
                 Participants who complete at least one thousand (1,000) Hours
                 of Service during the Plan Year and who are in one of the
                 following categories for the Plan Year shall be eligible to
                 share in the allocation of Employer basic contributions and
                 Forfeitures:

                 (1)      Participants who are employed on the last day of the
                          Plan Year or whose employment terminated on the last
                          day of the Plan Year; or

                 (2)      Participants whose employment terminated during the
                          Plan Year due to retirement at or after Normal
                          Retirement Age, death or disability.

                 Employer basic contributions and Forfeitures for the Plan Year
                 shall be allocated to Part I of each such Participant's
                 Employer Account in the proportion that such Participant's
                 number of units as of the Allocation Date bears to the total
                 number of units for all such Participants as of the Allocation
                 Date.  For purposes of this allocation, one (1) unit shall be
                 credited for each year of Vesting Service and one (1) unit
                 will be credited for each full one hundred dollars ($100) of
                 Compensation for the Plan Year.

         (b)     Employer Matching Contributions.  Employer matching
                 contributions pursuant to Section 3.01(b) hereof shall be
                 allocated to Part II of the respective Employer Accounts of
                 Participants on whose behalf such contributions were made.

         (c)     Qualified Matching Contributions.  Qualified Matching
                 Contributions pursuant to Section 3.01(c) hereof shall be
                 allocated as of the last day of the Plan Year to Part III of
                 the Employer Account of each Non- highly Compensated Employee
                 who was credited with an Employer matching contribution for
                 the Plan Year.  Each Participant's share in such Qualified
                 Matching Contributions shall be that amount which bears the
                 same ratio to the total Qualified Matching Contributions as
                 the Participant's salary deferral contributions for the Plan
                 Year bears to the total salary





                                     4 - 1
<PAGE>   32
                 deferral contributions for the Plan Year for all Non-highly
                 Compensated Employees entitled to share in the allocation.

         (d)     Salary Deferrals.  Salary deferral contributions pursuant to
                 Section 3.02(a) hereof shall be allocated as of each
                 Allocation Date to Part I of the Personal Account of each
                 Participant on whose behalf such contributions were made.

         Participant contributions pursuant to Section 3.02 hereof shall be
         allocated to the respective Personal Accounts of Participants who
         contributed such amounts or on whose behalf such contributions were
         made.

4.02     ALLOCATION OF INCOME.

         As of each Allocation Date, Income received on investments held by the
         Trustee shall be allocated to each Participant's Employer Account and
         Personal Account.

         The Income of each investment fund of the Trust Fund for the period
         ending with such Allocation Date shall be determined as the change in
         the fair market value of that investment fund since the last
         Allocation Date, after eliminating the effect of all non-investment
         transactions.

         Income of each investment fund shall be allocated as of each such
         Allocation Date as provided hereunder.  Income shall be allocated to
         each Participant's accounts in the ratio that the value of each such
         account as of the last Allocation Date bears to the total value of the
         Employer Accounts and Personal Accounts for all such persons as of the
         last Allocation Date.  These account values shall not include any
         accounts forfeited or segregated, or amounts withdrawn since the last
         Allocation Date, but may include contributions (adjusted for timing)
         since the last Allocation Date.

         For purposes of this section only, the term "Participants" shall
         include Retired Participants, present and former Employees and
         Beneficiaries who have account balances, but who would not otherwise
         be considered to be Participants under the Plan.

         Should the Plan Administrator determine that the strict application of
         the foregoing allocation procedures will not result in an equitable
         and non-discriminatory allocation among the accounts of Participants,
         it may modify its procedures for the purpose of achieving an equitable
         and non-discriminatory allocation in accordance with the general
         concepts of the Plan and the provisions of this article.

4.03     ADJUSTMENT TO ACCOUNTS.

         As soon as practicable after each Allocation Date, the value of each
         Employer Account and each Personal Account shall be determined as
         follows:

         (a)     Each Employer Account shall be equal to the value of such
                 account as of the last Allocation Date, less any payment or
                 Forfeiture from the account since the last





                                     4 - 2
<PAGE>   33
                 Allocation Date to, or on behalf of, such Participant, plus
                 the allocations of Employer contributions, Forfeitures and
                 Income specified in this article and any other adjustments
                 made to the Account since the last Allocation Date.

         (b)     Each Personal Account shall be equal to the value of such
                 account as of the last Allocation Date, plus any contributions
                 made on behalf of the Participant to the Plan (including
                 Participant salary deferral contributions) and less any
                 withdrawals or payments to or on behalf of such Participant
                 from such account since the last Allocation Date, plus the
                 allocation of Income specified in this article and any other
                 adjustments made to the Account since the last Allocation
                 Date.

4.04     MAXIMUM ANNUAL ADDITIONS TO PARTICIPANTS' ACCOUNTS.

         The annual addition to any Participant's accounts for any Plan Year
         shall not exceed the lesser of (i) thirty thousand dollars ($30,000),
         or, if greater, one-fourth of the defined benefit dollar limitation
         set forth in section 415(b)(1) of the Code as in effect for the
         limitation year, and (ii) twenty-five percent (25%) of such
         Participant's total cash compensation for the Plan Year.

         For purposes of this section and of Article 13 hereof, the term
         "compensation" shall mean wages within the meaning of Code section
         3401(a) and all other payments of compensation to an Employee by his
         Employer (in the course of the employer's trade or business) for which
         the Employer is required to furnish the Employee a written statement
         under Code sections 6041(d), 6051(a)(3), and 6052.  Compensation shall
         be determined without regard to any rules under Code section 3401(a)
         that limit the remuneration included in wages based on the nature or
         location of the employment or the services performed (such as the
         exception for agricultural labor in Code section 3401(a)(2)).

         For any self-employed individual, "Compensation" will mean earned
         income.

         For limitation years beginning after December 31, 1991, for purposes
         of applying the limitations of this section, compensation for a
         limitation year is the compensation actually paid or made available
         during such limitation year.

         The term "annual addition" for a Participant means the sum of the
         following for the Plan Year:

         (a)     contributions made by the Employer on behalf of the
                 Participant (including salary deferral contributions made
                 pursuant to Section 3.02(a) hereof); and

         (b)     Forfeitures allocated to a Participant's Employer Account, if
                 any;

         (c)     contributions made by the Participant, if any;

         (d)     amounts allocated to an individual medical account which is
                 part of a defined benefit plan, as described in Code section
                 415(l)(2); and





                                     4 - 3
<PAGE>   34
         (e)     amounts attributable to post-retirement medical benefits
                 allocated to a separate account of a key employee under a
                 welfare benefit fund as described in Code section 419A(d)(2).

         If a Participant is, or was, a participant at any time in both a
         qualified defined benefit pension plan and a qualified defined
         contribution plan ever maintained by the same employer, the sum of the
         defined benefit fraction and the defined contribution fraction in any
         limitation year may not exceed one (1).

         The term "defined benefit fraction" shall mean, for any Plan Year, a
         fraction the numerator of which is the projected annual benefit of the
         Participant under all qualified defined benefit pension plans
         maintained by the Employer (determined as of the close of the Plan
         Year), if any, and the denominator of which is the lesser of the
         following:

         (i)     one and four tenths (1.4) multiplied by one hundred percent
                 (100%) of the Participant's average total cash compensation
                 for the three (3) consecutive limitation years in which he
                 received the highest aggregate total cash compensation; and

         (ii)    one and twenty-five hundredths (1.25) multiplied by ninety
                 thousand dollars ($90,000) (or such greater amount as may be
                 determined by the Secretary of the Treasury).

         The term "defined contribution fraction" shall mean, for any Plan
         Year, a fraction the numerator of which is the sum of the annual
         additions to the Participant's accounts under all qualified defined
         contribution plans maintained by the Employer (determined as of the
         close of the Plan Year) and the denominator of which is the sum of the
         lesser of the following amounts determined for such year and for each
         prior year of service with the Employer:

         (i)     1.25, multiplied by the dollar limitation in effect under Code
                 section 415(c)(1)(A) for such year (determined without regard
                 to Code section 415(c)(6)), or

         (ii)    1.4, multiplied by the amount which may be taken into account
                 under Code section 415(c)(1)(B) (or Code section 415(c)(7), if
                 applicable) with respect to such individual under such plan
                 for such year.

         For purposes of determining annual additions, the limitation year 
         shall be the Plan Year.

         All qualified defined benefit pension plans (whether or not
         terminated) of an employer shall be treated as one (1) qualified
         defined benefit pension plan for purposes of applying the limitations
         of section 415(b), (c) and (e) of the Code.

         All qualified defined contribution plans (whether or not terminated)
         of an employer shall be treated as one (1) qualified defined
         contribution plan for purposes of applying the limitations of section
         415(b), (c) and (e) of the Code.





                                     4 - 4
<PAGE>   35
         In the case of a group of employers which constitutes a Controlled
         Group, all such employers shall be considered a single employer for
         purposes of applying the limitations of section 415 of the Code.

         If as a result of the allocation of Forfeitures, a reasonable error in
         estimating the compensation of a Participant, a reasonable error in
         determining the amount of elective deferral contributions (within the
         meaning of Code section 402(g)(3)) that may be made with respect to
         any individual under the limits of Code section 415, or other facts
         and circumstances allowed by regulation, the annual additions
         limitation is exceeded in any Plan Year, the excess annual addition
         shall be charged against the Participant's accounts in the following
         order of priority by the amount required to insure compliance with
         this Section:

         (i)     voluntary after-tax contributions;

         (ii)    salary deferral contributions which are not matchable salary
                 deferrals pursuant to Section 3.01(b);

         (iii)   matchable salary deferral contributions pursuant to Section
                 3.01(b) and Employer matching contributions, on a pro rata
                 basis;

         (iv)    all other Employer contributions.

         The portion of such excess which consists of voluntary after-tax
         contributions and salary deferral contributions shall be returned to
         the Participant.  The portion of such excess attributable to Employer
         contributions shall be treated as a Forfeiture for the Plan Year and
         shall be allocated to, and maintained as, a suspense account under the
         Plan to which Income is not allocated and which will be used to reduce
         Employer contributions along with other Plan Forfeitures as of the
         next date on which Employer contributions are allocated.  In addition,
         no Employer or Employee contributions may be made to the Plan until
         any excess maintained in a suspense account is exhausted.

         Notwithstanding any provision of the Plan to the contrary, if, in any
         limitation year, the sum of the defined benefit fraction and the
         defined contribution fraction exceed one (1.0), then the rate of the
         annual addition for any Participant shall be automatically reduced to
         the level necessary to prevent the limitations of this section from
         being exceeded with respect to such Participant.

4.05     SEPARATION OF FORFEITURES AND ACCOUNTS BY EMPLOYER.

         All Employers which are members of a Controlled Group shall be
         considered a single Employer for purposes of allocating Employer
         contributions and Forfeitures.  Employer contributions and Forfeitures
         for Employers which are not members of the Controlled Group shall be
         administered separately.





                                     4 - 5
<PAGE>   36
         Provided, however, that a single Trust Fund may be used for the
         investment of the funds of the Plan.

4.06     FAIR MARKET VALUE.

         The Plan Administrator shall cause to be determined the fair market
         value of all assets held by the Trustee in the Trust hereunder as of
         each Allocation Date.

4.07     INTERIM ALLOCATIONS.

         The Plan Administrator may direct a special allocation date in order
         to avoid prejudice either to continuing Participants or terminating
         Participants.  Such special allocation date shall be deemed equivalent
         to a regular Allocation Date, except that the allocations under
         Section 4.01 may be deferred until the next following regular
         Allocation Date.  Interim allocations, if any, shall be made on a
         nondiscriminatory basis.

4.08     ELECTION OF INVESTMENT FUND.

         Each Participant shall elect to have his Participant contributions and
         Employer contributions invested in the available investment funds in
         any combination of whole percentages that totals one hundred percent
         (100%).

         All elections hereunder shall be effective for the entire amount of
         both his Participant contributions and Employer contributions.  The
         form and manner of all elections under this section shall be
         prescribed by the Committee.

         Such investment funds shall remain a part of the Trust Fund, but shall
         be separately invested, with all investment income on such investments
         credited to the investment funds and all disbursements to, or on
         behalf of, the Participant changed thereto.

         A Participant may make, revise or revoke such election for the future
         investment of contributions made under this Plan provided for under
         this Section 4.08 as of the next Allocation Date, provided sufficient
         notice is provided to allow the modification to be made.  Such
         election shall remain effective for all subsequent contributions
         allocated on behalf of the Participant to the investment funds until
         the election is effectively modified or revoked.

         The transfer of existing balances in the Accounts of Participants
         between investment funds shall be permitted once each allocation
         period on the Allocation Date, provided sufficient notice is provided
         to allow the transfer to be made.

4.09     UNITS ACCOUNTING FOR INVESTMENT FUND

         The Committee may choose to maintain accounting of one or more of the
         investment funds on a "units" basis, wherein the market value of the
         assets in the fund are represented by units.  As of any date, the
         market value of a units fund will exactly equal the product of the
         number of units in the fund on that date and the value of each unit on





                                     4 - 6
<PAGE>   37
         that date.  Each Participant's Accounts with respect to such a fund
         will be maintained in units, and all additions to and subtractions
         from such Accounts will be in terms of units and will be based on the
         unit value as of the date of the transaction.  Investment earnings of
         the fund shall be accounted for based on the market value of the fund
         units, and the provisions of the Plan regarding the allocation of
         investment earnings shall not apply to a fund being maintained on a
         units basis.  The provisions of this Section shall automatically
         supersede any conflicting provisions in the Plan.

                        IN-SERVICE WITHDRAWALS AND LOANS

5.01     WITHDRAWALS FROM PARTICIPANTS' EMPLOYER ACCOUNTS.

         In-service withdrawals from a Participant's Employer Account are not 
         permitted.

5.02     WITHDRAWALS FROM PART I OF PARTICIPANTS' PERSONAL ACCOUNTS.

         While a Participant or a former Participant is in the Service of the
         Employer, he may apply to the Plan Administrator to withdraw all or a
         part of the amount attributed to Part I of his Personal Account.  Such
         a request shall be granted only if the Participant has demonstrated an
         immediate and heavy financial need arising from a hardship situation
         or has attained fifty nine and one half (59-1/2) years of age.  The
         Committee shall determine whether an emergency financial hardship has
         been proven by the Participant in accordance with regulations issued
         by the Secretary of the Treasury pursuant to section 401(k) of the
         Code and the Secretary of the U.S. Department of Labor pursuant to
         ERISA section 408.  A maximum of one (1) withdrawal under this Section
         5.02 may be made in each half of the calendar year.

         The determination of whether a Participant or a former Participant has
         an immediate and heavy financial need and no other resources available
         to satisfy such need shall be made in accordance with the following
         conditions.

         (a)     Financial Need Test.  The immediate and heavy financial needs
                 for which a hardship withdrawal may be granted shall be
                 limited to the following:

                 (1)      Expenses for medical care described in Code section
                          213(d) previously incurred by the Participant, the
                          Participant's spouse, or any dependents of the
                          Participant (as defined in Code section 152) or
                          necessary for these persons to obtain medical care
                          described in Code section 213(d);

                 (2)      Costs directly related to the purchase of a principal
                          residence for the Participant (excluding mortgage
                          payments);

                 (3)      Payment of tuition and related education fees for the
                          next twelve (12) months of post-secondary education
                          for the Participant, or the Participant's spouse,
                          children, or dependents (as defined in Code section
                          152);

                 (4)      Payments necessary to prevent the eviction of the
                          Participant from the Participant's principal
                          residence or foreclosure on the mortgage on that
                          residence; or





                                     5 - 1
<PAGE>   39
                 (5)      Other expenses which the Commissioner of the Internal
                          Revenue Service indicates will be deemed to be made
                          on account of such need.

                 The amount of any hardship withdrawal granted pursuant to this
                 Section 5.02(a) shall be limited to the lesser of:

                 o        the actual amount of the salary deferral
                          contributions made on behalf of the Participant or
                          former Participant, without regard to Income
                          allocable thereto, less the amount of salary deferral
                          contributions previously withdrawn; and

                 o        the amount required to relieve the financial need
                          plus amounts necessary to pay any federal, state, or
                          local income taxes or penalties reasonably
                          anticipated to result from the hardship distribution.

         (b)     Resources Test.  To qualify for a hardship withdrawal pursuant
                 to Section 5.02(a), the Participant or former Participant must
                 certify that the financial need giving rise to the hardship
                 cannot be met from other resources that are reasonably
                 available to the participant, such as:

                 (1)      insurance reimbursement;

                           GENERAL BENEFIT PROVISIONS


6.01     FORM OF BENEFIT PAYMENT.

         (a)     In General.  The normal form of payment shall be a single lump
                 sum, except that payment of a benefit attributable to a
                 transfer of assets from an Annuity Transfer Plan shall be made
                 in conformance with Section 6.01(b).  In lieu of this normal
                 form of payment, a Participant may elect to have his benefit
                 paid in accordance with one or more of the following optional
                 forms of payments, subject to Sections 6.01(b) or (c), if
                 applicable.

                 (1)      Paid in a single sum; or

                 (2)      Paid in installments as nearly equal as practicable
                          for a period not to exceed the Participant's life
                          expectancy or the life expectancy of the Participant
                          and his Beneficiary.  The Retired Participant or, if
                          the Retired Participant is deceased, the Beneficiary
                          may nevertheless, as of any subsequent date, elect to
                          have the balance then remaining paid in a single sum;
                          or

                 (3)      Applied to the purchase of a nontransferable,
                          immediate life annuity contract.  Such annuity may
                          not be in any form that will provide for payments
                          over a period extending beyond the period described
                          in Section 6.03(c) hereof.

                 Such election must be in writing, in such form as the
                 Committee shall uniformly and nondiscriminatorily require, and
                 may be submitted at any time during the ninety (90) day period
                 preceding the first day of the first period for which an
                 amount is paid as a benefit and following the date which the
                 Participant is provided with information concerning the
                 optional forms of benefit and the Participant's right, if any,
                 to defer payment of his benefit.  Such notice shall be
                 provided at least thirty (30) and no more than ninety (90)
                 days before the first day of the period described in the
                 preceding sentence.  If a distribution is one to which
                 sections 401(a)(11) and 417 of the Code do not apply, such
                 distribution may commence less than thirty (30) days after the
                 notice required under section 1.411(a)-11(c) of the Income Tax
                 Regulations is given, provided that:

                          (i)     the Plan Administrator clearly informs the
                                  Participant that the Participant has a right
                                  to a period of at least thirty (30) days
                                  after receiving the notice to consider the
                                  decision of whether or not to elect a
                                  distribution (and, if applicable, a
                                  particular distribution option), and

                          (ii)    the Participant, after receiving the notice,
                                  affirmatively elects a distribution.

                 If the Retired Participant does not elect an option, such
                 benefits shall be paid or applied in accordance with the
                 option described in (a) above.

         (b)     Annuity Benefit Payment Provisions.  Any annuity contract
                 purchased for a Participant pursuant to an election of the
                 payment form provided in Section 6.01(a)(3) or pursuant to the
                 requirement of Code section 401(a)(11)(B)(iii) that the Plan
                 purchase the annuity contract because of a transfer from an
                 Annuity Transfer Plan with respect to the Participant, shall
                 be in the form of a Qualified Joint and Survivor Annuity to
                 the Participant and his Spouse, or if the Participant does not
                 have a Spouse, in the form of an annuity for the life of the
                 Participant.  However, payment may be made in an alternate
                 form or to an alternate joint annuitant, if a qualified
                 election to waive payment in the above- described form and
                 manner is made in conformance with subsection (1) below,
                 following receipt of the notice described in (2) below:

                 (1)      Qualified Election.  An election shall be a qualified
                          election, effective to waive payment in the Qualified
                          Joint and Survivor Annuity form or the straight life
                          annuity form, if applicable, only if:

                          (i)     the Participant's Spouse consents in writing
                                  to the election;

                          (ii)    the election designates a specific
                                  Beneficiary, including any class of
                                  Beneficiaries or any contingent
                                  Beneficiaries, which may not be changed
                                  without spousal consent (or the Spouse
                                  expressly permits designations by the
                                  Participant without any further spousal
                                  consent);

                          (iii)   the election designates a form of benefit
                                  payment which may not be changed without
                                  spousal consent (or the Spouse expressly
                                  permits designations by the Participant
                                  without any further spousal consent);

                          (iv)    the Spouse's consent acknowledges the effect
                                  of the election; and

                          (v)     the Spouse's consent is witnessed by the
                                  Committee, its representative, or by a notary
                                  public.

                          If it is established to the satisfaction of the
                          Committee, or its representative that there is no
                          Spouse or that the Spouse cannot be located, a waiver
                          will be deemed a qualified election.  Any consent by
                          a Spouse obtained under this provision (or
                          establishment that the consent of a Spouse may not be
                          obtained) shall be effective only with respect to
                          such Spouse.  A consent that permits designations by
                          the Participant without any requirement of further
                          consent by such Spouse must acknowledge that the
                          Spouse has the right to limit consent to a specific
                          joint annuitant, and a specific form of benefit where
                          applicable, and that the Spouse voluntarily elects to
                          relinquish either or both of such rights.  A
                          revocation of a prior waiver may be made by a
                          participant without the consent of the Spouse at any
                          time before the Annuity Starting Date.  The number of
                          revocations shall not





                                     6 - 2
<PAGE>   42
                          be limited.  No consent obtained under this provision
                          shall be valid unless the Participant has received
                          notice as provided in paragraph (2) below.

                          Notwithstanding the above, if the Participant has not
                          been credited with at least one (1) Hour of Service
                          on or after August 23, 1984, then any waiver by the
                          Participant will be deemed to be a qualified
                          election, and consent by the Participant's Spouse is
                          not required.

                 (2)      Notice of Qualified Joint and Survivor Annuity.  At
                          least thirty (30) and no more than ninety (90) days
                          prior to the Annuity Starting Date, the Committee
                          shall provide each affected Participant a notice in
                          the form of a written explanation concerning the
                          Qualified Joint and Survivor Annuity containing:

                          (i)     the terms and conditions of a Qualified Joint
                                  and Survivor Annuity;

                          (ii)    the Participant's right to make, and the
                                  effect of, an election to waive the Qualified
                                  Joint and Survivor Annuity form of benefit;

                          (iii)   the rights of the Participant's Spouse and;

                          (iv)    the right to make, and the effect of, a
                                  revocation of a previous election to waive a
                                  Qualified Joint and Survivor Annuity.

         (c)     Rollovers.  Notwithstanding anything expressed or implied to
                 the contrary above, Part III of a Participant's Personal
                 Account shall be distributed to him in a single sum unless the
                 Participant shall elect an alternate form of payment under
                 Section 6.01(a).  In no event shall payment of such amount be
                 required to be made in a Qualified Joint and Survivor Annuity
                 form or in a straight life annuity form.

6.02     GENERAL COMMENCEMENT OF BENEFITS RULE.

         Notwithstanding any other provisions of the Plan, but in addition to
         such provisions (as applicable), unless the Participant elects
         otherwise in writing, distribution of benefits shall begin no later
         than the sixtieth (60th) day after the close of the Plan Year in which
         the latest of the following events occurs:

         (a)     the date the Participant attains sixty-five (65) years of age;

         (b)     the date which is the tenth (10th) anniversary of the first
                 (1st) day of the Plan Year in which the Participant commenced
                 participation in the Plan; or

         (c)     the date the Participant terminates Service with the Employer.

         If a Participant is still in Service at his attainment of age seventy
         and one-half (70-1/2), then his entire Accounts shall then be paid or
         applied on his behalf in accordance with the provisions of Section
         6.01 hereof, except that installment payments under Section 6.01(a)(2)
         shall not be available.





                                     6 - 3
<PAGE>   43
         If the amount of the payment required to commence on the date
         determined under this section cannot be ascertained by such date, or
         if it is not possible to make such payment on such date because the
         Committee has been unable to locate the Participant after making
         reasonable efforts to do so, then a payment retroactive to such date
         may be made no later than sixty (60) days after the earliest date on
         which the amount can be ascertained under the Plan or the date on
         which the Participant is located (whichever is applicable).

                          take precedence over any inconsistent provisions of
                          this Plan.

         (b)     Required Beginning Date.  The entire interest of a Participant
                 must be distributed or begin to be distributed no later than

                 Participant or of the Participant's Spouse or Beneficiary
                 shall not be required to make a distribution required under

                                  who is not a five-percent (5%) owner who
                                  attains age seventy and one-half (70-1/2)
                                  during 1988 and who has not retired as of
                                  January 1, 1989, is April 1, 1990.

                 (2)      Five-percent (5%) owner.  A Participant is treated as
                          a five-percent (5%) owner for purposes of this
                          subsection (b) if such Participant is a five-percent
                          (5%) owner as defined in section 416(i) of the Code
                          (determined in accordance with section 416 but
                          without regard to whether the Plan is top-heavy) at
                          any time during the Plan Year ending with or within
                          the calendar year in which such owner attains age
                          sixty-six and one-half (66-1/2) or any subsequent
                          Plan Year.

                 (3)      Once distributions have begun to a five-percent (5%)
                          owner under this section, those distributions must
                          continue even if the Participant ceases to be a
                          five-percent (5%) owner in a subsequent year.

         (c)     Duration of Benefits.  Benefits to a Participant shall be
                 distributed, beginning not later than the required beginning
                 date set forth in subsection (b) in accordance with
                 regulations, for a period not exceeding the life of such
                 Participant or, if applicable, the joint lives of such
                 Participant and his Beneficiary, or over the life expectancy
                 of such Participant or, if applicable, the joint life
                 expectancies of the Participant and his Beneficiary.  For
                 purposes of this section, "life expectancy" shall mean the
                 life expectancy (or joint and last survivor expectancy)
                 calculated using the attained age of the Participant (or
                 designated Beneficiary) as of the Participant's (or designated
                 Beneficiary's) birthday in the applicable calendar year,
                 reduced by one (1) for each calendar year which has elapsed
                 since the date life expectancy was first calculated.  If life
                 expectancy is being recalculated, the applicable life
                 expectancy shall be the life expectancy as so recalculated.
                 The applicable calendar year shall be the first distribution
                 calendar year, and if life expectancy is being recalculated
                 such succeeding calendar year.  If annuity payments commence
                 before the required beginning date, the applicable calendar
                 year is the year such payments commence.  Life expectancy and
                 joint and last survivor expectancy are computed by use of the
                 expected return multiples in Tables V and VI of section 1.72-9
                 of the Treasury Regulations.

         (d)     Minimum Amount to be Distributed Each Year.  If the
                 Participant's interest is to be distributed in other than a
                 single sum, the following distribution rules shall apply on or
                 after the required beginning date.

                 (1)      The amount to be distributed each year, beginning
                          with distributions for the first distribution
                          calendar year shall not be less than the quotient
                          obtained by dividing the Participant's benefit by the
                          lesser of (i) the applicable life expectancy as
                          described in Section 6.04(c) or (ii) if the
                          Participant's Spouse is not the designated

                          Beneficiary, the applicable divisor determined from
                          the table set forth in Q&A-4 of section 1.401(a)(9)-2
                          of the proposed regulations.

                 (2)      The minimum distribution required for the
                          Participant's first distribution calendar year must
                          be made on or before the Participant's required
                          beginning date.  The minimum distribution for other
                          calendar years, including the minimum distribution
                          for the distribution calendar year in which the
                          employee's required beginning date occurs, must be
                          made on or before December 31 of that distribution
                          calendar year.

                 (3)      Distribution calendar year.  For purposes of this
                          section, the term "distribution calendar year" means
                          a calendar year for which a minimum distribution is
                          required.  For distributions beginning before the
                          Participant's death, the first distribution calendar
                          year is the calendar year immediately preceding the
                          calendar year which contains the Participant's
                          required beginning date.  For distributions beginning
                          after the Participant's death, the first distribution
                          calendar year is the calendar year in which
                          distributions are required to begin pursuant to
                          section 6.04(e) below.

         (e)     Death distribution provisions.

                 (1)      Distribution Beginning Before Death.  If the
                          Participant dies after distribution of his or her
                          interest has begun, the remaining portion of such
                          interest will continue to be distributed at least as
                          rapidly as under the method of distribution being
                          used prior to the Participant's death.

                 (2)      Distribution Beginning After Death.  If the
                          Participant dies before distribution of his or her
                          interest begins, distribution of the Participant's
                          entire interest shall be completed by December 31 of
                          the calendar year containing the fifth anniversary of
                          the Participant's death except to the extent that an
                          election is made to receive distributions in
                          accordance with (i) or (ii) below:

                          (i)     if any portion of the Participant's interest
                                  is payable to a designated Beneficiary,
                                  distributions may be made over the life or
                                  over a period certain not greater than the
                                  life expectancy of the designated Beneficiary
                                  commencing on or before December 31 of the
                                  calendar year immediately following the
                                  calendar year in which the Participant died;

                          (ii)    if the designated Beneficiary is the
                                  Participant's surviving spouse, the date
                                  distributions are required to begin in
                                  accordance with (i) above shall not be
                                  earlier than the later of (1) December 31 of
                                  the calendar year immediately following the
                                  calendar year in which the Participant died
                                  and (2) December 31 of the calendar year in
                                  which the Participant would have attained age
                                  70 1/2.

                          If the Participant has not made an election pursuant
                          to this subsection (e)(2) by the time of his or her
                          death, the Participant's designated Beneficiary must
                          elect the

                          method of distribution no later than the earlier of
                          (1) December 31 of the calendar year in which
                          distributions would be required to begin under this
                          section, or (2) December 31 of the calendar year
                          which contains the fifth anniversary of the date of
                          death of the Participant.  If the Participant has no
                          designated Beneficiary, or if the designated
                          Beneficiary does not elect a method of distribution,
                          distribution of the Participant's entire interest
                          must be completed by December 31 of the calendar year
                          containing the fifth anniversary of the Participant's
                          death.

                 (3)      For purposes of subsection (e)(2) above, if the
                          surviving Spouse dies after the Participant, but
                          before payments to such Spouse begin, the provisions
                          of subsection (e)(2), with the exception of paragraph
                          (ii) therein, shall be applied as if the surviving
                          Spouse were the Participant.

                 (4)      For the purposes of this subsection (e),
                          distributions of a Participant's interest is
                          considered to begin on the Participant's required
                          beginning date (or, if subsection (e)(3) above is
                          applicable, the date distribution is required to
                          begin to the surviving Spouse pursuant to subsection
                          (e)(2) above).  If distribution in the form of an
                          annuity irrevocably commences to the Participant
                          before the required beginning date, the date
                          distribution is considered to begin is the date
                          distribution actually commences.

         Except as otherwise provided in this section, amounts attributable to
         elective salary deferrals pursuant to Section 3.02(a) hereof shall not
         be distributed earlier than upon the occurrence of one of the
         following events:

                 who continues employment with the corporation acquiring such
                 assets;

         (e)     with regard to an Employee who continues employment with such
                 subsidiary, the date of the sale or other disposition by the
                 Employer of such corporation's interest in a subsidiary;

         entitled to receive any benefit under the Plan, and the value of the
         nonforfeitable benefit is not greater than (or at the time of any
         prior distribution was not greater than) three thousand five hundred
         dollars ($3,500), the benefit shall be paid to such person in a single
         sum after such Participant incurs a Break in Service but before the
         end of the second Plan Year following the Plan Year during which the
         Participant ceases to participate in the Plan.  Provided, however,
         that for distributions made on or after January 1, 1993, the foregoing

                 are not permitted for amounts under two hundred dollars
                 ($200).

                          the Code; and the portion of any distribution that is
                          not includible in gross income (determined without

                          the spouse or former spouse.

                 (4)      Direct rollover:  A direct rollover is a payment by
                          the Plan to the eligible retirement plan specified by
                          the distributee.

         If benefits under the Plan are to be paid in the form of an annuity,
         then the Trustee shall purchase such annuity contracts from a life
         insurance company licensed to do business in the state in which the
         Sponsor maintains offices, utilizing for such purchase the entire
         amount in the Accounts of the Participant as of the date of the
         purchase.  Any annuity contract which is purchased hereunder to
         provide benefits otherwise payable under the Plan, and which is
         distributed to a former Participant or Beneficiary, shall be endorsed
         as "nontransferable."

                   RETIREMENT, DEATH AND DISABILITY BENEFITS


7.01     BENEFITS UPON RETIREMENT.

         Upon attainment of Normal Retirement Age, a Participant shall be one
         hundred percent (100%) vested in his Accounts.  Upon retirement
         following attainment of his Normal Retirement Age or after having
         satisfied the conditions for and taken early retirement under the
         Trustmark National Bank Pension Plan, a Participant shall receive as
         the value of his retirement benefit hereunder the amounts in his
         Accounts determined on the Allocation Date coincident with or
         immediately preceding his retirement, increased by any Employer and
         Participant contributions allocated after such Allocation Date,
         reduced by any payments and withdrawals made from such accounts since
         such Allocation Date and adjusted for any Income allocated or other
         adjustments made after such Allocation Date.

7.02     DEATH BENEFITS.

         In the event of the death of a Participant or Retired Participant
         (other than a Retired Participant receiving benefits pursuant to
         Section 6.01 hereof) prior to complete distribution of his Accounts,
         the amount of the death benefit on his behalf shall be one hundred
         percent (100%) of both his Employer Account and Personal Account,
         determined on the Allocation Date immediately preceding the date of
         the distribution, adjusted to reflect any Employer or Participant
         contributions or trustee to trustee transfers allocated after such
         Allocation Date, and any payments or withdrawals made from such
         accounts since such preceding Allocation Date.  Notwithstanding the
         foregoing, however, the Employer Account for a Retired Participant
         whose participation in the Plan terminated before the date of his
         death and during the Plan Year coincident with the date of his death
         shall be determined by applying the vested percentage described in
         Section 8.01 hereof unless the Participant had reached his Normal
         Retirement Date.

7.03     PAYMENT OF DEATH BENEFITS.

         (a)     In General.  Except as required in Section 7.03(b) below, the
                 benefit payable under Section 7.02 shall be paid in a single
                 sum.  In lieu thereof, a Participant may elect to have such
                 benefit paid in any of the optional forms set forth in Section
                 6.01(a).  Provided, however, that any elected optional form of
                 payment shall comply with the form of payment limitations set
                 forth in Section 6.03 hereof.  Such election must be in
                 writing, in such form as the Committee shall uniformly and
                 nondiscriminatorily require and may be submitted at any time,
                 beginning on the date the Participant enters the Plan and
                 ending on the date of his death.  Payment of the death benefit
                 shall be made to the Participant's surviving Spouse or to his
                 otherwise designated Beneficiary





                                     7 - 1
<PAGE>   50
                 (if the Participant is not survived by a Spouse or if his
                 Spouse has consented to designation of an alternate
                 Beneficiary in conformance with Section 7.04).

         (b)     Annuity Benefit Payment Provisions.  Notwithstanding Section
                 7.03(a) above, the benefit payable under Section 7.02 will be
                 paid as an annuity for the life of the surviving Spouse of the
                 Participant if the Participant died before his Annuity
                 Starting Date and either:

                 (1)      the Participant elected prior to his death that any
                          benefits payable to him under the Plan would be paid
                          in the form provided in Section 6.01(a)(3) and the
                          Participant is survived by a Spouse who has not
                          waived payment in such form and has not consented to
                          the designation of an alternate Beneficiary in
                          conformance with Section 7.04 as of the date of the
                          Participant's death; or

                 (2)      part or all of the benefit to be distributed to the
                          Participant under this Plan is attributable to a
                          transfer to this Plan from an Annuity Transfer Plan
                          and the Participant is survived by a Spouse who has
                          not waived payment in the annuity form and has not
                          consented to designation of an alternate Beneficiary
                          in conformance with Section 7.04 prior to the
                          Participant's death.

                 Notwithstanding the above, the Spouse may elect to receive
                 this death benefit in an optional form of benefit payment
                 pursuant to subsection (a) hereof as if the Spouse were the
                 Participant pursuant to a qualified election at any time prior
                 to ninety (90) days before payment of the death benefit
                 actually commences.

         (c)     Qualified Election.  Only a qualified election hereunder by
                 the Participant shall be effective to waive the form of
                 payment, or the payment to the Spouse, of the death benefit
                 provided under Section 7.03(b) of the Plan.  Such waiver under
                 a qualified election shall be in writing at any time after the
                 Participant elected the annuity form of payment (if
                 applicable) and before the Participant's death, and shall be
                 consented to by his Spouse during such period.  Any such
                 Spouse's consent to a waiver shall be witnessed by the
                 Committee, or its representative, or by a notary public and,
                 if an alternate Beneficiary other than a Spouse is to be
                 named, shall provide a specifically named alternate
                 Beneficiary. Notwithstanding this consent requirement, if the
                 Participant establishes to the satisfaction of the Committee
                 that such written consent cannot be obtained because there is
                 not such a Spouse, or that such Spouse cannot be located, then
                 consent to a waiver shall be deemed to have, in fact, been
                 made, and such deemed consent to a spousal waiver shall be
                 considered as a qualified election.  Any consent necessary
                 under this subsection shall be valid only with respect to the
                 Spouse who signs the consent, or in the case of a deemed
                 qualified election, the relevant Spouse, and shall not be
                 valid with respect to any other Spouse.  Additionally, a
                 revocation of a prior waiver may be made by a Participant in
                 writing delivered to the Committee without the consent of any
                 such Spouse at any time before the commencement of benefits.
                 The number of such revocations shall not be limited.





                                     7 - 2
<PAGE>   51
                 However, any subsequent waiver or change of alternate
                 Beneficiary in a prior spousal consent shall require a new
                 spousal consent.

                 Notwithstanding the above, if the Participant has not been
                 credited with at least one (1) Hour of Service on or after
                 August 23, 1984, then any waiver by the Participant will be
                 deemed to be a qualified election, and consent by the
                 Participant's Spouse is not required.

         (d)     Notice of Spouse's Survivor Annuity.  The Committee shall
                 provide each Participant whose Spouse may receive a survivor
                 annuity pursuant to Section 7.03(b), a written explanation of
                 the survivor annuity described in Section 7.03(b) hereof in
                 such terms and in such manner as is comparable to the
                 explanation provided pursuant to Section 6.01(b)(2) with
                 respect to the Qualified Joint and Survivor Annuity notice.
                 The Committee shall provide such Participant with a written
                 explanation of the survivor annuity within a reasonable period
                 ending after Section 7.03(b) first applies to the Participant.

         (e)     Time of Payment.  Subject to the time limitations set forth in
                 Sections 6.02 and 6.03 hereof, the death benefit commencement
                 date shall be no later than as soon as practicable after the
                 end of the Plan Year in which the death of the Participant
                 occurs.

         (f)     Discharge of Liability.  Payment of the death benefit to the
                 Beneficiary of the deceased Participant shall fully discharge
                 the Trustee, the Committee and the Employer, and each of them,
                 from any and all liability hereunder as to such deceased
                 Participant.  The Trustee, the Committee and the Employer, and
                 each of them, shall not be responsible for the ultimate
                 disposition of such benefit in accordance with any will or
                 other testamentary disposition made by such Participant, or in
                 accordance with the intestacy provisions of any law.

7.04     DESIGNATION OF BENEFICIARY.

         Subject to the rights of a surviving Spouse described herein, each
         Participant or Retired Participant shall have the right to designate
         the Beneficiary to receive the death benefit on his behalf, and to
         revoke any such designation.  Each such designation, or revocation
         thereof, shall be evidenced by a written instrument filed with the
         Committee and signed by the Participant or Retired Participant.
         Unless the conditions which follow for the designation of a
         Beneficiary other than the Spouse are satisfied, the Beneficiary of a
         Participant or Retired Participant shall be the surviving Spouse, if
         any, whether or not so designated in the written instrument filed with
         the Committee and even if no such instrument is filed.  Designation of
         a Beneficiary other than the Spouse shall be valid only if either:

         (a)     the Spouse consents in writing to such designation,
                 acknowledging the effect thereof, witnessed by a notary public
                 or Plan representative;





                                     7 - 3
<PAGE>   52
         (b)     the Retired Participant or Participant, although married at
                 the time of the designation, is ultimately not survived by his
                 Spouse; or

         (c)     the surviving Spouse cannot be located.

         Such spousal consent obtained pursuant to (a) shall be irrevocable.
         If the Participant or Retired Participant is survived by a Spouse
         other than the Spouse who consented to designation of another as
         Beneficiary, the consent of the former Spouse shall be ineffective.

         If no designation of Beneficiary is on file with the Plan
         Administrator at the time of the death of a Participant or Retired
         Participant, or if such designation is not effective for any reason,
         and if there is no surviving Spouse, the death benefit shall be
         payable to the estate of the Participant or Retired Participant (which
         shall be conclusively deemed to be the Beneficiary designated to
         receive such death benefit).

7.05     DISABILITY BENEFITS.

         In the event the Committee determines that a Participant incurs
         Disability while still an Employee, such Participant shall be entitled
         to one hundred percent (100%) of both his Employer Account and
         Personal Account, determined on the Allocation Date coincident with or
         immediately preceding the date of his Disability, increased by any
         Employer and Participant contributions allocated after such Allocation
         Date, reduced by any payments and withdrawals made from his accounts
         since such preceding Allocation Date and adjusted for any Income
         allocated or other adjustments made after such Allocation Date.

         Subject to the provisions hereof concerning the death of a former
         Participant prior to the commencement of benefits hereunder, any
         amounts due a disabled Participant pursuant to this article from his
         accounts shall be paid or applied for his benefit in accordance with
         the provisions described in Section 6.01 hereof for the payment of
         retirement benefits; provided, however, that upon the Participant's
         election the commencement date shall be any date after his Disability
         occurred and before the earliest date he could retire under the Plan.
         With respect to a Participant who has a Spouse, such early
         commencement of disability benefits attributable to amounts
         transferred from an Annuity Transfer Plan may be made only upon his
         Spouse's consent pursuant to a qualified election within the meaning
         of Sections 6.01(b)(1) and 7.03(c) hereof.  Notwithstanding the above,
         if the Participant has not been credited with at least one (1) Hour of
         Service on or after August 23, 1984, then any waiver by the
         Participant will be deemed to be a qualified election, and consent by
         the Participant's Spouse is not required.

         In the event of the death of the Participant subsequent to the date
         his Disability occurred and prior to the commencement of his
         disability benefits hereunder, the amount payable on behalf of such
         Participant shall be paid as a death benefit as provided otherwise in
         this article.

                              TERMINATION BENEFITS


8.01     BENEFITS UPON TERMINATION OF SERVICE.

         A Participant whose Service terminates for reasons other than
         retirement on or after his Normal Retirement Date, death or Disability
         shall be entitled to a vested percentage, determined at the date his
         Service terminates, of Parts I and II of his Employer Account, and one
         hundred percent (100%) of Part III of his Employer Account and his
         Personal Account.  Such accounts will be determined as of the
         Allocation Date coincident with or immediately preceding the date the
         Participant's Service terminates, increased by any Employer and
         Participant contributions allocated to such accounts after such
         Allocation Date, reduced by any payments and withdrawals from the
         accounts since such preceding Allocation Date and adjusted for any
         Income allocated or other adjustments made after such Allocation Date.

         The vested percentage of Parts I and II of a Participant's Employer
         Account shall be determined from the following schedule:


<TABLE>
<CAPTION>
                     YEARS OF                           Vested
                 Vesting Service                      Percentage
                 ---------------                      ----------
                   Less than 5                             0%
                    <S>                                  <C>
                    5 or more                            100%
</TABLE>



         Provided, however, that the vested percentage shall be one hundred
         percent (100%) for a Participant on and after his Normal Retirement
         Age.

8.02     FORFEITURES.

         The portion of an Employer Account to which a former Participant is
         not entitled, as provided in Section 8.01 hereof, shall be a
         Forfeiture as of the last day of the Plan Year in which occurs the
         earlier of the following dates:

         (a)     the date the former Participant is paid the entire vested
                 amount of his Accounts, and

         (b)     the date the former Participant incurs five (5) consecutive
                 Breaks in Service.

         For purposes of this Section, if the value of an Employee's vested
         account balance is zero, the former Participant shall be deemed to
         have received a distribution of such vested account balance and the
         Employer Account shall be treated as a Forfeiture as of the date such
         Employee incurs a Break in Service.





                                     8 - 1
<PAGE>   54
         If a former Participant receives or is deemed to have received a
         distribution from his Employer Account due to termination of
         participation in the Plan, no later than the close of the second Plan
         Year following the Plan Year during which he ceases to be a
         Participant, which distribution is:

         (c)     equal to his vested Employer Account, but less than one
                 hundred percent (100%) of such account, and

         (d)     in an amount not exceeding thirty-five hundred dollars
                 ($3,500) or, if greater, which the Participant elected to
                 receive,

         and he subsequently resumes Service before he incurs five (5)
         consecutive Breaks in Service, he may repay such distribution to the
         Plan.  Such repayment must be made before the earlier of the date the
         Participant incurs five (5) consecutive Breaks in Service and the
         fifth anniversary of the date of the Participant's resumption of
         Service following the Break in Service.  In the event of such
         repayment, the amount of the Participant's Employer Account at the
         date of the distribution shall be reestablished.

         If a benefit cannot be paid to a Retired Participant or his
         Beneficiary because he cannot be found, such benefit (subject to
         overruling law) shall be treated as a Forfeiture but, if treated as a
         Forfeiture, shall be reinstated if a claim is made by that Participant
         or his Beneficiary.  Such reinstatement shall be made from then
         available Forfeitures arising from the Accounts of other Retired
         Participants.  If the amount of available Forfeitures is insufficient
         for such reinstatement, then the Employer shall contribute an amount
         to complete the reinstatement.

         Any Forfeitures remaining after the reinstatements described above
         shall be allocated to Part I of the Employer Accounts of other
         Participants in accordance with the provisions of Section 4.01(a)
         hereof.

8.03     PAYMENT OF BENEFITS UPON TERMINATION OF SERVICE.

         Subject to the provisions hereof concerning the death of a former
         Participant prior to the complete distribution of benefits hereunder,
         any amounts due the Participant pursuant to this article from his
         Accounts shall be paid or applied for his benefit at his Normal
         Retirement Date in accordance with Section 6.01 hereof.
         Notwithstanding the above, such former Participant may elect an
         earlier commencement date, except that payment from the former
         Participant's Employer Account may not occur until said former
         Participant has incurred a Break in Service.  With respect to a
         participant who has a Spouse, such early commencement of benefits
         attributable to amounts transferred from an Annuity Transfer Plan may
         be made only upon his Spouse's consent pursuant to a qualified
         election within the meaning of Sections 6.01(b)(1) and 7.03(c) hereof.
         Notwithstanding the above, if the Participant has not been credited
         with at least one (1) Hour of Service on or after August 23, 1984,
         then any waiver by the Participant will be deemed to be a qualified
         election, and consent by the Participant's Spouse is not required.





                                     8 - 2
<PAGE>   55
         In the event of the death of the Participant subsequent to the date
         his Service terminates and prior to the commencement of his benefits,
         the amount payable under this article on behalf of such Participant
         shall be paid as provided in Article 7 hereof.

         In the event of the Disability of the Participant, and certification
         thereof by the Committee to the Trustee, subsequent to the date his
         Service terminates and prior to the commencement of his benefits, the
         amount payable under this article to such Participant shall be paid as
         provided in Article 7 hereof.

8.04     SPECIAL VESTING DUE TO RE-EMPLOYMENT.

         If a distribution is made from a Retired Participant's Employer
         Account at a time when the Retired Participant has a vested percentage
         of less than one hundred percent (100%) of such Employer Account, and
         the Retired Participant resumes Service before the non-vested portion
         of such Employer Account becomes a Forfeiture, then the portion of the
         Participant's Employer Account which he did not receive as a
         distribution shall be established on his behalf as a "separate
         account."  At any later relevant time, the amount to which the
         Participant shall be entitled from the "separate account" shall be
         computed according to the following formula:

                  X  =  P  x  (AB  +  (R  x  D))  -  (R  x  D)

         For purposes of solving this equation, "X" is the amount to which the
         Participant is entitled, "P" is his vested percentage at the relevant
         time, "AB" is his Account balance at the relevant time, "R" is the
         ratio of his Account balance at the relevant time to his Account
         balance immediately after the distribution, and "D" is the amount of
         the distribution.  Provided, however, that a separate account is not
         required to be established so long as Account balances are maintained
         under a method that has the same effect as the method described above.

         the following information in language calculated to be understood by
         the claimant:





                                     9 - 2
<PAGE>   58
         (a)     the specific reason or reasons for the denial;

         (b)     specific reference to pertinent Plan provisions on which the
                 denial is based;

         (c)     a description of any additional material or information
                 necessary for the claimant to perfect the claim and an
                 explanation of why such material or information is necessary;
                 and

         (d)     an explanation of the claims review procedure in the Plan.

         Upon receipt of such a notice of denial, or if such a notice is not
         furnished but the claim has not been granted within sixty (60) days of
         its filing, the claimant or his duly authorized representative may
         appeal to the Plan Administrator for a full and fair review.

         In submitting a request for review, the claimant or his duly
         authorized representative may request a review upon written
         application to the Plan Administrator, may review pertinent documents,
         and may submit comments in writing.  Such request for review must be
         made within sixty (60) days of the receipt by the claimant of the
         notice of denial (or within sixty (60) days of the expire of the sixty
         (60) day period beginning with the date of the filing of the claim, if
         no such notice is received during such period).

         The Plan Administrator shall respond promptly to a request for review
         and shall deliver a written decision which shall include, in a manner
         calculated to be understood by the claimant, the decision itself,
         specific reasons therefor and specific references to the pertinent
         Plan provisions on which the decision is based.  The decision shall be
         made not later than one hundred twenty (120) days after receipt of a
         request for review.

         Any decision by the Plan Administrator shall be conclusive and binding
         upon all persons, subject to the claims review procedure described in
         this Section 9.05 and subject to judicial review where it is shown by
         clear and convincing evidence that the Plan Administrator acted in an
         arbitrary and capricious manner.

                           THE TRUST AND THE TRUSTEE


10.01    THE TRUST; GENERAL DUTIES OF THE TRUSTEE.

         The Sponsor hereby continues the Trust previously established with the
         Trustee pursuant to the terms of the Plan.  The Trustee shall hold all
         property received by it hereunder, which, together with the income and
         gains therefrom and additions thereto, shall constitute the Trust
         Fund.  The Trustee shall manage, invest and reinvest the Trust Fund,
         collect the income thereof, and make payments therefrom, all as
         provided in this Plan and Trust.

         The Trustee shall be responsible only for the property actually
         received by it hereunder.  It shall have no duty or authority to
         compute any amount to be paid to it by the Employer or to bring any
         action or proceeding to enforce the collection from the Employer of
         any contribution to the Trust Fund.

         Title to the Trust Fund, including all funds and investments held
         hereunder by the Trustee, shall be and remain in the Trustee, and no
         Participant, Retired Participant or Beneficiary shall have any legal
         or equitable right or interest in the Trust Fund except to the extent
         that such rights or interests are expressly granted under the
         provisions of the Plan.

         The Trust Fund may not be used or diverted for purposes other than the
         exclusive benefit of Participants, Retired Participants and
         Beneficiaries for the proper satisfaction of liabilities to such
         persons covered by the Trust.

10.02    GENERAL POWERS.

         The Trustee shall have all the powers necessary for the performance of
         its duties as Trustee.  The Trustee shall have the following powers
         and immunities and be subject to the following duties:

         (a)     The Trustee shall receive all contributions hereunder and
                 apply such contributions as hereinafter set forth.  The
                 Trustee shall have the custody of and safely keep all cash,
                 securities, property and investments, including any insurance
                 company contracts, received or purchased in accordance with
                 the terms hereof.

         (b)     Subject to any limitations that may be contained elsewhere in
                 the Plan, the Trustee shall take control and management of the
                 Trust Fund and shall hold, sell, buy, exchange, invest and
                 reinvest the corpus and income of the Trust Fund.  All
                 contributions paid to the Trustee under the Plan shall be held
                 and administered by the





                                     10 - 1
<PAGE>   60
                 Trustee as a single Trust Fund, and the Trustee shall not be
                 required to segregate and invest separately any part of the
                 Trust Fund representing accruals or interests of individual
                 Participants in the Plan, except as provided in Section 6.02
                 hereof.

         (c)     The Trustee may invest and reinvest the funds of the Trust
                 Fund in any property, real, personal or mixed, wherever
                 situate, and whether or not productive of income or consisting
                 of wasting assets, including, without limitation, common and
                 preferred stock, bonds, notes, debentures, leaseholds,
                 mortgages (including without limitation, any collective or
                 part interest in any bond and mortgage or note and mortgage),
                 certificates of deposit, and oil, mineral or gas properties,
                 royalties, interests or rights (including equipment pertaining
                 thereto), without being limited to the classes of property in
                 which trustees are authorized by law or any rule of court to
                 invest trust funds and without regard to the proportion any
                 such property may bear to the entire amount of the Trust Fund.

         (d)     The Trustee may invest and reinvest all or any portion of the
                 Trust Fund collectively with funds of other retirement plan
                 trusts exempt from tax under section 501(a) of the Code,
                 including, without limitation, power to invest collectively
                 with such other funds through the medium of one (1) or more
                 common, collective or commingled trust funds which have been
                 or may hereafter be established and maintained by the Trustee,
                 the instrument or instruments establishing such trust fund or
                 funds, as amended from time to time, being made part of this
                 Trust by reference so long as any portion of the Trust Fund
                 shall be invested through the medium thereof.

         (e)     The Trustee is expressly authorized to invest all or part of
                 the Trust Fund in savings accounts, time deposits,
                 certificates of deposit, money market accounts, repurchase
                 agreements and any other interest- bearing accounts which bear
                 a reasonable interest rate (regardless of the term of such
                 deposits or investments), issued by the Trustmark National
                 Bank or any of its affiliates.  The Trustee is further
                 expressly authorized to utilize the discount brokerage
                 operation, if any, offered by Trustmark National Bank or its
                 affiliates.

         (f)     The Trustee shall, at the direction of the Chief Executive
                 Officer of the Sponsor, invest up to one hundred percent
                 (100%) of the portion of the Trust Fund which is not
                 attributable to salary deferral contributions, voluntary
                 Participant contributions, rollover contributions and
                 trustee-to-trustee transfers in Qualifying Employer
                 Securities.  The Chief Executive Officer is authorized to
                 issue such direction at his discretion.  For purposes of this
                 section, the term Qualifying Employer Securities shall mean
                 Employer securities (or securities of a member of the
                 Controlled Group of the Employer) which are stock or
                 marketable obligations, such as bonds, debentures, notes or
                 certificates, or other evidence of indebtedness, as defined in
                 Section 401(d)(5) of ERISA.

         (g)     The Trustee may sell or exchange any property or asset of the
                 Trust Fund at public or private sale, with or without
                 advertisement, upon terms acceptable to the Trustee and





                                     10 - 2
<PAGE>   61
                 in such manner as the Trustee may deem wise and proper.  The
                 proceeds of any such sale or exchange may be reinvested as is
                 provided hereunder.  The purchaser of any such property from
                 the Trustee shall not be required to look to the application
                 of the proceeds of any such sale or exchange by the Trustee.

         (h)     The Trustee shall have full power to mortgage, pledge, lease
                 or otherwise dispose of the property of the Trust Fund without
                 securing any order of court therefor, without advertisement,
                 and to execute any instrument containing any provisions which
                 the Trustee may deem proper in order to carry out such
                 actions.  Any such lease so made by the Trustee shall be
                 binding, notwithstanding the fact that the term of the lease
                 may extend beyond the termination of the Plan.

         (i)     The Trustee shall have the power to borrow money upon terms
                 agreeable to the Trustee and pay interest thereon at rates
                 agreeable to the Trustee, and to repay any debts so created.

         (j)     The Trustee may participate in the reorganization,
                 recapitalization, merger or consolidation of any corporation
                 wherein the Trustee may own stock or securities and may
                 deposit such stock or other securities in any voting trust or
                 protective committee or like committee or trustee, or with the
                 depositories designated thereby, and may exercise any
                 subscription rights or conversion privileges, and generally
                 may exercise any of the powers of any owner with respect to
                 any stock or other securities or property comprising the Trust
                 Fund.

         (k)     The Trustee may, through any duly authorized officer or proxy,
                 vote any share of stock which the Trustee may own from time to
                 time except for stock of Trustmark National Bank ("Bank") on
                 the following matters.  On any matter which involves a sale of
                 substantially all of the assets or the stock of the Bank or a
                 transfer of a majority or more of the stock of the Bank
                 through merger, consolidation or other means in which control
                 of the Bank is transferred to another party, each Participant
                 or Beneficiary shall be entitled to direct the Trustee to vote
                 a certain number of shares of stock of the Bank determined
                 under the following formula:  multiply the total number of
                 Bank shares held by the Trustee by a fraction the numerator of
                 which is the Employer Account balance of such Participant or
                 Beneficiary and the denominator of which is the total Employer
                 Account balances of all Participants and Beneficiaries.

         (l)     The Trustee shall retain in cash and keep unproductive of
                 income such funds as from time to time it may deem advisable.
                 The Trustee shall not be required to pay interest on any such
                 cash in its hands pending investment, nor shall the Trustee be
                 responsible for the adequacy of the Trust Fund to discharge
                 any and all payments under the Plan.  All persons dealing with
                 the Trustee are released from inquiry into the decision or
                 authority of the Trustee to act.

         (m)     The Trustee may hold stocks, bonds, or other securities in its
                 own name as Trustee, with or without the designation of said
                 trust estate, or in the name of a nominee selected by it for
                 the purpose, but said Trustee shall nevertheless be obligated
                 to





                                     10 - 3
<PAGE>   62
                 account for all securities received by it as part of the
                 corpus of the trust estate herein created, notwithstanding the
                 name in which the same may be held.

         (n)     The Trustee may consult with legal counsel (who may be of
                 counsel to the Employer or the Plan Administrator) concerning
                 any questions which may arise with reference to the
                 construction of this Plan, its duties hereunder, or any action
                 which it proposes to take or omit.

         (o)     The Trustee may employ such counsel, accountants and other
                 agents as it shall deem advisable.  The Trustee may charge the
                 compensation of such counsel, accountants and other agents and
                 the Trustee's compensation for its services in such amounts as
                 may be agreed upon from time to time by the Employer and the
                 Trustee, and any other expenses necessary in the
                 administration of this Plan against the Trust Fund to the
                 extent they are not paid by the Employer.  However, only those
                 fees and expenses which constitute reasonable expenses of
                 administering the Plan may be charged to the Trust.

         (p)     The Trustee shall have the power to designate a bank or trust
                 company as depository of the funds or property of the Trust
                 and also to retain investment counsel, and the Trustee may
                 deposit funds in its commercial banking department (if any)
                 without making bond.

         (q)     Without diminution or restriction of the powers vested by law
                 or elsewhere in this Plan, but subject to all the provisions
                 of the Plan, the Trustee, without the necessity of procuring
                 any judicial authorization therefor or approval thereof, shall
                 be vested with and, in the application of its best judgment
                 and discretion on behalf of the beneficiaries of this Plan,
                 shall be authorized to exercise all or any of the powers
                 specifically permitted by statute or judicial decision in, or
                 with respect to, the state in which the Trustee principally
                 does business.

10.03    RELIANCE ON PLAN ADMINISTRATOR AND EMPLOYER.

         Until notified pursuant to Article 9 hereof that any person authorized
         to act for the Plan Administrator (such as a Committee member) has
         ceased to act or is no longer authorized to act for the Plan
         Administrator, the Trustee may continue to rely on the authority of
         such person.  The Trustee may rely upon any certificate, notice or
         direction purporting to have been signed on behalf of the Plan
         Administrator which the Trustee believes to have been signed by or on
         behalf of the Plan Administrator.  The Trustee may rely upon any
         certificate, notice or direction of the Employer which the Trustee
         believes to have been signed by a duly authorized officer, principal
         or agent of the Employer.  The Trustee may request instructions in
         writing from the Plan Administrator on other matters and may rely and
         act thereon.

10.04    ACCOUNTS AND REPORTS.

         The Trustee shall keep an accurate record of its administration of the
         Trust Fund, including a detailed account of all investments, receipts
         and disbursements, and other transactions hereunder.  All accounts,
         books and records relating hereto shall be open for inspection to any
         person designated by the Committee or the Sponsor at all reasonable
         times.  Within sixty (60) days following the close of each Plan Year,
         the Trustee shall file with the Plan Administrator a written report
         setting forth all investments, receipts and disbursements and other
         transactions during the Plan Year, and such report shall contain an
         exact description of all securities purchased, exchanged or sold, the
         cost or net proceeds of sale, and shall show the securities and
         investments held at the end of such Plan Year, and the cost and fair
         market value of each item thereof, as carried on the books of the
         Trustee.

         The Trustee shall also provide the Plan Administrator with such other
         information in its possession as may be necessary for the Plan
         Administrator to comply with the reporting and disclosure requirements
         of ERISA.

         Upon the expiration of ninety (90) days from the date of filing such
         report, the Trustee shall be forever released and discharged from all
         liability and accountability to anyone with respect to the recording
         of its acts and transactions shown in such statement, except with
         respect to any such acts or transactions as to which the Plan
         Administrator shall file with the Trustee written objections within
         such ninety (90) day period.

10.05    DISBURSEMENTS.

         The Trustee, upon written instructions from the Plan Administrator,
         shall make distributions or payments, or both, including monthly
         payments, to the Participants, Retired Participants, and Beneficiaries
         who qualify for such benefits.  The Trustee shall have no liability to
         the Employer, the Plan Administrator or any other person in making
         such distributions or payments.  The Trustee shall not be required to
         determine or make any investigation to determine the identity or
         mailing address of any person entitled to benefits under the Plan and
         shall have discharged its obligation in that respect when it shall
         have sent checks and other papers by ordinary mail to such person or
         persons at such addresses as may be certified to it in writing by the
         Plan Administrator.

10.06    PAYMENT IN KIND.

         Whenever the Trustee is empowered hereunder to make any payment or
         distribution, the Trustee shall have the power, in its sole
         discretion, to make such payment in cash or in kind, or partly in cash
         and partly in kind.  In no event shall any payment in kind be made in
         the form of a life annuity.  The assets of the Trust Fund shall be
         valued, for the purposes of making, or of computing the amount of,
         such payment or distribution, at their fair market value at the dates
         of such payment or distributions.

10.07    AUTHORITY OF TRUSTEE.

         At no time during the administration of the Trust Fund shall the
         Trustee be required to obtain any court approval of any act required
         of it in connection with the performance of its duties or in the
         performance of any act required of it in the administration of its
         duties as Trustee.  The Trustee shall have full authority to exercise
         its judgment in all matters and at all times without court approval of
         such decisions; provided, however, that if any application to, or
         proceeding or action in, the courts is made, only the Sponsor and the
         Trustee shall be necessary parties, and no Participant in the Plan or
         other person having an interest in the Trust Fund shall be entitled to
         any notice or service of process.  Any judgment entered in such
         proceeding or action shall be conclusive upon all persons claiming an
         interest under the Trust Fund.

10.08    REMOVAL OR RESIGNATION OF TRUSTEE.

         The Trustee may at any time be removed as Trustee of the Plan by
         action of the Board of Directors of the Sponsor and written notice to
         the Trustee, such removal to be effective sixty (60) days after such
         notice is given.

         The Trustee may resign as Trustee of the Plan upon written notice to
         the Sponsor, such resignation to be effective sixty (60) days after
         such notice is given.

         Upon mutual, written agreement by the Sponsor and the Trustee, the
         sixty (60) day period in this section may be waived or a shorter
         period substituted.

10.09    SUCCESSOR TRUSTEE.

         In the event of the resignation or removal of the Trustee, the Sponsor
         shall appoint a successor trustee in place of the resigned or removed
         Trustee on or before the effective date of such resignation or
         removal.  In the absence of such action, the Sponsor shall be deemed
         to have terminated the Plan, and the termination provisions of Article
         11 shall apply.

         On or before the effective date of the removal or resignation, the
         Trustee shall file with the Sponsor a written report setting forth all
         investments, receipts and disbursements and other transactions
         effected by it since the end of the preceding Plan Year.  Such report
         shall be in the same form and be subject to the same requirements as
         the annual report.

         The Trustee, if not paid by the Sponsor, is authorized to reserve such
         sum of money or to liquidate such property and reserve the proceeds
         thereof as it may deem advisable for the payment of its expenses or
         charges in connection with the settlement of its account or otherwise,
         and any such balance of such reserve remaining after the payment of
         such expenses and charges shall be paid over to the successor trustee
         or trustees, or to the Participants in the event of termination.

10.10    TRUST FUNDING POLICY; PARTIES IN INTEREST.

         From time to time the Plan Administrator shall communicate to the
         Trustee the current funding policy and method that have been
         established to carry out the objectives of the Plan.

         Upon the written request of the Trustee, the Sponsor shall file with
         the Trustee a roster of the names of all persons, corporations,
         partnerships, organizations and entities which are "parties in
         interest" with respect to the Plan, as that term is defined in ERISA.

10.11    TRUSTEE TO TRUSTEE TRANSFERS.

         The Plan Administrator shall have the power to authorize the
         acceptance of a direct transfer to this Plan of plan assets
         attributable to a Participant's participation in another qualified
         plan; provided, however, that any restrictions on distributions of
         such transferred assets under such other plan shall be maintained
         under this Plan with respect to such assets.  Likewise, the Plan
         Administrator shall have the power to authorize the Trustee to make
         such a direct transfer of assets from this Plan attributable to a
         Participant's participation in this Plan to another qualified pension,
         profit sharing or stock bonus plan.

         A separate bookkeeping subaccount for his transfers shall be
         established on behalf of a Participant under his Personal Account, and
         such transfers shall be treated as Participant contributions for
         purposes of investment and allocation of Income.  Likewise, for
         purposes of the withdrawal and distribution of benefits pursuant to
         Articles 5, 6, 7 and 8 hereof, the subaccount shall be treated as part
         of the Personal Account, subject to any additional restrictions
         required by the preceding paragraph.  The balance of each such account
         shall be fully vested at all times.

         Such direct trustee to trustee transfers shall not be considered (i)
         as contributions by the Employer under Section 3.01 of this Plan, (ii)
         in determining the maximum benefits permissible under the Plan
         pursuant to Section 4.04 hereof or (iii) in determining the Top Heavy
         Ratio in Section 13.02(j) hereof, provided they are transfers
         initiated by the Employee and made from a plan maintained by an
         employer which is not in the Controlled Group.

10.12    INVESTMENT MANAGER.

         The Sponsor may appoint in writing an Investment Manager or Investment
         Managers to manage all or any portion of the assets of the Plan and
         may revoke any such appointment previously made.  While such an
         appointment is in effect, the relations among the Plan Administrator,
         Sponsor, Investment Manager, and Trustee shall be governed by the
         following provisions:

         (a)     The Sponsor shall certify to the Trustee the name or names of
                 any Investment Manager appointed by it to manage the
                 investment or reinvestment of all or any





                                     10 - 7
<PAGE>   66
                 portion of the Trust Fund.  Such certificate shall also state
                 that the Investment Manager has acknowledged his Fiduciary
                 status with respect to the Plan in writing.

         (b)     The Trustee shall segregate any portion of the Trust Fund held
                 by it which will be subject to the management of an Investment
                 Manager into one or more separate accounts to be known as
                 investment manager accounts and shall charge any expenses
                 related to investments directed by an Investment Manager
                 against such accounts.  Each Investment Manager shall have the
                 right and power to manage the investment and reinvestment of
                 his investment manager account.  The Trustee shall follow the
                 directions of the Investment Manager with respect to the
                 account of such Investment Manager and shall not be obligated
                 to invest or otherwise manage any such investment manager
                 account.  All directions given by an Investment Manager to the
                 Trustee shall be in writing, signed by an officer or a partner
                 of the Investment Manager or by such other person or persons
                 as may be designated by such officer or partner.  Subject to
                 such conditions as may be approved by the Sponsor and Trustee,
                 the Investment Manager may place direct orders for the
                 purchase or sale of securities or other property for its
                 investment manager account, provided, that the Trustee shall
                 nevertheless retain custody of the assets comprising said
                 account.

         (c)     If the Sponsor, by written notice to the Trustee, terminates
                 the authority of an Investment Manager but does not appoint a
                 successor to manage the investment and reinvestment of the
                 account of such Investment Manager, the portion of the Fund
                 then held in such investment manager account shall return to
                 the unsegregated portion of the Fund and the Trustee shall
                 have authority to manage the investment and reinvestment of
                 such account.  Until receipt of a written notice terminating
                 the authority of an Investment Manager, the Trustee shall be
                 fully protected in relying upon the latest prior written
                 notice of appointment of an Investment Manager.

         (d)     Any Investment Manager may, in writing, authorize the Trustee
                 to invest any portion of his investment manager account in
                 short-term investments.  The Trustee, in its sole discretion,
                 may make such investments either directly or by investment
                 collectively with other assets, including but not limited to
                 investment in any common, commingled, collective, mutual or
                 pooled trust fund established and maintained by the Trustee or
                 any affiliate of the Trustee for the investment of funds
                 administered in a fiduciary capacity.

         (e)     The Trustee shall not be responsible for any loss caused by
                 its acting upon any notice, direction or certification of any
                 Investment Manager appointed by the Sponsor which the Trustee
                 reasonably believes to be genuine.  The Trustee shall have no
                 duty to question any direction, action or inaction of any
                 Investment Manager taken as provided in this section.  The
                 Trustee shall have no duty to review the securities or other
                 property held in any investment manager account or to make any
                 suggestions to any Investment Manager or to the Employer with
                 respect to the investment, reinvestment, or disposition of
                 investments in any investment manager account.  The

<PAGE>   67
                 Trustee shall not be responsible for the results arising from
                 the Trustee's compliance with the instructions of any
                 Investment Manager.

         (f)     The Trustee shall not be responsible for determining the
                 reasonableness of any compensation paid to or agreed to be
                 paid to an Investment Manager.  Any such compensation to an
                 Investment Manager shall be paid from the Trust Fund, if the
                 Plan Administrator so directs.

         (g)     With respect to any share of stock in the investment manager
                 account, the Trustee may, through any duly authorized officer
                 or proxy, vote any such stock.

                     AMENDMENT AND TERMINATION OF THE PLAN


11.01    AMENDMENT OF PLAN.

         The Board of Directors of the Sponsor shall have the right at any
         time, and from time to time, to modify, alter or amend the Plan in
         whole or in part by instrument in writing duly executed.

         Provided, however, that the Plan shall not be amended in the following
         respects:

         (a)     the duties, powers and responsibilities of the Trustee shall
                 not be increased without the written consent of the Trustee;

         (b)     subject to Section 12.05 hereof, no amendment may be made to
                 permit any part of the funds of the Trust to be used for or
                 diverted to purposes other than for the exclusive benefit of
                 Participants, Retired Participants and their Beneficiaries or
                 for administration expenses of the Plan;

         (c)     no amendment may be made, unless it is necessary to meet the
                 requirements of any federal law or regulation, which shall
                 reduce the benefits which have accrued or the nonforfeitable
                 percentage applicable to any Participant, Retired Participant
                 or Beneficiary prior to the later of the date of adoption or
                 the effective date of such amendment, nor shall any amendment
                 to the Plan eliminate an optional form of distribution
                 provided under Section 6.01 hereof except as may be permitted
                 by federal law or regulation; and

         (d)     no amendment to the vesting provision in Section 8.01 hereof
                 shall become effective with respect to a Participant who has
                 completed three (3) or more years of Service at the date of
                 adoption of such amendment unless such Participant is given
                 the opportunity to elect irrevocably to have his
                 nonforfeitable benefits computed without regard to such
                 amendment.  The election period shall be a period of sixty
                 (60) days after the latest of:

                 (i)      the date of adoption of the amendment,

                 (ii)     the effective date of the amendment, and

                 (iii)    the date written notification of the amendment is
                          furnished such Participant.

                 An executed copy of any amendment to the Plan shall be
                 furnished the Trustee as soon as practicable after the date of
                 adoption thereof.

11.02    INTENT TO CONTINUE THE PLAN.

         The Employer has established the Plan with the bona fide intention and
         expectation that from year to year it will make contributions as
         herein provided.  However, the Employer realizes that it may become
         inadvisable to continue such contributions.  The Employer shall have
         the right to modify, suspend or discontinue contributions to the Plan
         at any time and from time to time, and such action shall not be deemed
         to be a termination of the Plan unless it constitutes a complete
         discontinuance of Employer contributions to the Plan.

11.03    TERMINATION OF THE PLAN BY THE SPONSOR; PARTIAL TERMINATION.

         In the event the Sponsor concludes that it is impossible or
         inadvisable to continue the Plan, the Board of Directors of the
         Sponsor shall have the right to terminate the Plan by an appropriate
         action which shall specify the date of termination.  A certified copy
         of a writing reflecting such action shall be delivered to the
         Committee and to the Trustee, and as soon as possible thereafter the
         Committee shall send or deliver to each then Participant a notice of
         such action.

         If a determination is made that the Plan has experienced a partial
         termination, then the rights of the affected Participants, Retired
         Participants and Beneficiaries to benefits accrued to the date of such
         partial termination shall be nonforfeitable.

11.04    TERMINATION OF THE PLAN UPON CERTAIN EVENTS.

         The Plan shall automatically terminate upon the occurrence of any of 
         the following events:

         (a)     discontinuance or liquidation of the Sponsor's business;

         (b)     the merger or consolidation of the Sponsor into any other
                 entity, unincorporated business organization or corporation,
                 or the sale by the Sponsor of substantially all of its assets
                 to any entity, unincorporated business organization, or
                 corporation which shall fail to adopt and continue the Plan
                 within ninety (90) days from the effective date of such
                 consolidation, merger or sale of assets; or

         (c)     failure of the Sponsor to appoint a successor trustee in place
                 of a Trustee who has resigned or been removed on or before the
                 effective date of such resignation or removal as provided in
                 Section 10.09.

11.05    DISTRIBUTION OF TRUST FUND UPON TERMINATION.

         Upon complete termination of the Plan, or upon discontinuance of
         Employer contributions to the Plan, the balance in each Participant's
         or Retired Participant's accounts (after payment of all expenses and

         of termination) shall become nonforfeitable and each Participant,
         Retired Participant or Beneficiary shall be entitled to receive any
         amounts then credited to his accounts in the Trust Fund.

         The Trustee shall make payment of such amounts in a single sum.  Upon
         the distribution of all of the Trust Fund as aforesaid, the Trustee
         shall be discharged from all obligations under the Trust and no
         Participant, Retired Participant or Beneficiary shall have any further
         rights or claim therein.

11.06    TERMINATION OF PLAN WITH RESPECT TO AN ADOPTING EMPLOYER.

         Each Adopting Employer reserves the right to terminate the Plan at any
         time with respect to Employees of the Adopting Employer by action of
         its Board of Directors.  The Adopting Employer shall also have the
         right to suspend contributions to the Plan from time to time, and such
         suspension of contributions shall not be deemed to be a termination of
         the Plan with respect to the Employees of the Adopting Employer unless
         it constitutes a complete discontinuance of Employer contributions to
         the Plan.

         In the event of termination of the Plan only with respect to the
         Employees of the Adopting Employer, the Plan Administrator shall
         direct that the portion of the Trust Fund attributable to Employees of
         the Adopting Employer be segregated by the Trustee into a separate
         fund.

         The portion of the Trust Fund which is so segregated shall be retained
         in a separate trust fund and applied in one of the following methods,
         at the discretion of the Committee.

         (a)     If the Adopting Employer shall demonstrate conclusively,
                 within the one hundred eighty (180) day period immediately
                 following termination of the Plan with respect to its
                 Employees, that it has established a successor retirement plan
                 and trust for the benefit of its Employees which is qualified
                 under sections 401(a) and 501(a), respectively, of the Code,
                 then such assets shall be transferred to the successor
                 trustee.

         (b)     If the Adopting Employer shall fail, within the one hundred
                 eighty (180) day period immediately following termination of
                 the Plan with respect to its Employees, to establish a
                 successor retirement plan and trust which is qualified under
                 sections 401(a) and 501(a), respectively, of the Code, then
                 such assets shall be distributed for the benefit of the
                 Employees of the Adopting Employer in accordance with the
                 method described in Section 11.05 hereof.

         At the discretion of the Plan Administrator, the one hundred eighty
         (180) day period may be extended.

12.01    DUTIES OF THE EMPLOYER.

         The Sponsor shall furnish the Trustee with the information required
         herein.  Each Employer shall make its contributions as the same may be
         appropriated by due action, which contributions may be in cash or in
         other property acceptable to the Trustee.  The Employer shall keep
         accurate books and records with respect to its Employees and their
         compensation.

12.02    RIGHT OF EMPLOYER TO DISCHARGE EMPLOYEES.

         The adoption and maintenance of the Plan shall not be deemed to
         constitute a contract between the Employer and any Employee, or to be
         a consideration for, or an inducement or condition of, the employment
         of any person.

12.03    INFORMATION TO BE FURNISHED.

         As soon as practicable after the close of each Plan Year, each
         Employer shall deliver to the Plan Administrator a full and complete
         list of all Employees entitled to participate in the Plan during such
         Plan Year, together with the information required to perform the
         allocations described in Article 4 hereof with respect to such Plan
         Year.

         As soon as possible after the execution of the Plan, and from time to
         time thereafter, the Sponsor and the Plan Administrator shall certify
         to the Trustee the names and specimen signatures of any
         representatives who have authority to act on behalf of the Sponsor
         with respect to the Plan.

12.04    COMMUNICATIONS FROM SPONSOR TO TRUSTEE.

         The Trustee may rely upon and shall be protected in acting upon any
         information furnished to it by the Sponsor in writing subscribed by a
         duly authorized agent of the Sponsor.  Any certification by the
         Sponsor of the information required or permitted to be certified to
         the Trustee pursuant to the provisions of the Plan, shall, for all
         purposes of the Plan, be binding upon all parties in interest.

12.05    NO REVERSION TO EMPLOYER.

         The Employer has no beneficial interest in the Trust Fund, and no part
         of the Trust Fund shall ever revert or be repaid to the Employer,
         directly or indirectly, except, if, and to the extent, permitted by
         the Code and applicable regulations thereunder for the following:

         (a)     upon initial non-qualification pursuant to Section 14.10
                 hereof;


         (b)     in the event that the deduction of an Employer contribution to
                 the Plan under section 404 of the Code is disallowed, in which
                 case the contribution (to the extent disallowed) shall be
                 returned to the Employer, upon the request of the Employer
                 within one (1) year after the disallowance of the deduction;
                 or

         (c)     in the event that the Employer contribution is made by mistake
                 of fact, in which case the amount of such mistaken
                 contribution shall be returned to the Employer provided no
                 more than one (1) year has elapsed since the date of payment
                 by the Employer of the mistaken contribution.

12.06    INDEMNIFICATION.

         To the extent permitted by law the Sponsor shall indemnify from any
         loss or expense the Plan Administrator or any individual member of the
         Committee, in connection with the good faith discharge of duties under
         the Plan.

12.07    ADOPTION OF PLAN BY ADOPTING EMPLOYERS.

         Notwithstanding anything herein to the contrary, with the
         authorization of the Board of Directors of the Sponsor any corporation
         or entity affiliated with the Sponsor through complete or partial
         ownership by the Sponsor or by any owner thereof or which is otherwise
         cooperating with the Sponsor for purposes of establishing a retirement
         plan may adopt the Plan as an Adopting Employer in a manner
         satisfactory to the Board of Directors of the Sponsor.  As part of its
         adoption of the Plan, each Adopting Employer shall designate, subject
         to the agreement and approval of the Sponsor and the provisions of
         Code section 413(c), whether or not its participation in the Plan
         shall constitute a single plan, within the meaning of the regulations
         under section 414(l) of the Code, with the participation in the Plan
         of the Sponsor and/or other Adopting Employers.  Such designation may
         be amended by the Adopting Employer at any subsequent date.

         For purposes of the payment of benefits due a Participant from the
         Plan:

         (a)     if the Participant is an Employee of an Employer which has
                 elected to maintain a plan which is not such a single plan,
                 only that part of the Trust Fund attributable to the Employer
                 shall be available;

         (b)     if the Participant is an Employee of an Employer which has
                 elected to maintain such a single plan, that part of the Trust
                 Fund attributable to all Employers maintaining the single plan
                 shall be available.

         An Adopting Employer may terminate participation in the Plan at any
         time with respect to Employees of the Adopting Employer by action of
         its Board of Directors as provided in Section 11.06 hereof, subject to
         the applicable provisions therein depending on

         whether or not the Adopting Employer has elected to maintain a single
         plan with the Sponsor and/or other Adopting Employers.

         All Employers which are Adopting Employers as of January 1, 1994,
         shall be deemed to have elected to maintain a single plan with the
         plan of the Sponsor.

                   PROVISIONS APPLICABLE TO A TOP HEAVY PLAN


13.01    TOP HEAVY PLANS.

         The provisions of this article are designed to meet the requirements
         of section 416 of the Code and shall automatically supersede any
         conflicting provisions in the Plan in every Plan Year in which this
         Plan is or becomes a Top Heavy Plan.  Provided, however, that if the
         provisions of this article are in conflict with final regulations
         issued by the Secretary of the Treasury with respect to Top Heavy
         Plans, then such final regulations shall supersede the provisions of
         this article to the extent not otherwise specifically prohibited by
         law.

13.02    DEFINITIONS.

         For purposes of this article, and only this article, unless a term
         defined in this article is the subject of explicit reference elsewhere
         in the Plan, the following terms when used herein, unless the context
         clearly indicates otherwise, shall have the meanings set forth
         hereinafter:

         (a)     "Compensation" shall mean, for each Employee, Compensation as
                 that term is defined in Section 4.04 of the Plan, plus amounts
                 contributed by the Employer pursuant to a salary reduction
                 agreement which are excludible from the employee's gross
                 income under section 125, section 402(a)(8), section 402(h) or
                 section 403(b) of the Code.  However, "Compensation" shall not
                 include compensation in excess of the applicable dollar limits
                 in Section 1.10(d) and 1.10(e).

         (b)     "Determination Date" shall mean, with respect to any Plan Year
                 subsequent to the first Plan Year, the last day of the
                 preceding Plan Year.  For the first Plan Year of the Plan, the
                 Determination Date shall be the last day of such Plan Year.

         (c)     "Key Employee" shall mean any Employee or former Employee (or
                 Beneficiary of such Employee) who, at any time during the
                 determination period, was (i) an officer of the Employer
                 having an annual Compensation greater than fifty percent (50%)
                 of the maximum dollar limitation in effect under section
                 415(b)(1)(A) of the Code for any such Plan Year, (ii) an owner
                 of one (1) of the ten (10) largest interests in the Employer
                 if such interest is greater than one-half percent (1/2%) and
                 such individual's Compensation exceeds the maximum dollar
                 limitation under section 415(c)(1)(A) of the Code, (iii) a
                 five percent (5%) or more owner of the Employer or (iv) a one
                 percent (1%) or more owner of the Employer who has an annual
                 Compensation of more than one hundred and fifty thousand
                 dollars ($150,000).  The term "determination period" shall
                 mean the Plan Year containing the Determination Date

                 and the four (4) preceding Plan Years.  The determination of
                 who is a Key Employee shall be made in accordance with section
                 416(i)(1) of the Code and regulations thereunder.  For
                 purposes hereof, the term "officer" shall mean an
                 administrative executive who is in regular and continued
                 service.  An Employee who merely has the title of an officer,
                 but not the authority of an officer, is not to be considered
                 an officer hereunder.  Furthermore, for purposes hereof, at
                 any time during a determination period, no more than fifty
                 (50) Employees of all members of a Controlled Group, or, if
                 lesser, the greater of three (3) individuals or ten percent
                 (10%) of such Employees, shall be treated as officers
                 hereunder.  The officers subject to these preceding
                 limitations shall be comprised of the individual officers
                 selected from the group of all individuals who were officers
                 in the current Plan Year of the determination period or any of
                 the four (4) preceding Plan Years in the determination period,
                 who had the largest average annual compensation throughout the
                 total of those five (5) Plan Years in the determination
                 period.  For purposes of (ii) herein, if two (2) employees
                 have the same interest in the Employer, the Employee having
                 the greater annual Compensation (without regard to the dollar
                 limitation of Section 13.02(a) hereof) from the Employer shall
                 be treated as having a larger interest.  Likewise, for
                 purposes hereof, the term "owner" shall mean an individual
                 considered to be an owner within the meaning of section 318 of
                 the Code; provided, however, that subparagraph (c) of section
                 318(a)(2) shall be applied by substituting "5 percent" for "50
                 percent".

         (d)     "Non-Key Employee" shall mean any Employee who is not a Key
                 Employee.

         (e)     "Permissive Aggregation Group" shall mean the Required
                 Aggregation Group of plans plus any other plan or plans of the
                 Employer, as selected by the Employer, which, when considered
                 as a group with the Required Aggregation Group, would continue
                 to satisfy the requirements of sections 401(a)(4) and 410 of
                 the Code.

         (f)     "Present Value" shall mean, if the Employer also now or ever
                 maintains a qualified defined benefit pension plan, the
                 present value of a benefit based only on the interest and
                 mortality rates specified in that plan.

         (g)     "Required Aggregation Group" shall mean as follows:

                 (1)      each qualified plan of the Employer in which at least
                          one (1) Key Employee participates or participated at
                          any time during the determination period (regardless
                          of whether or not the plan terminated), and

                 (2)      any other qualified plan of the Employer which
                          enables a plan described in the preceding subsection
                          (1) to meet the requirements of sections 401(a)(4) or
                          410 of the Code.

         (h)     "Super Top Heavy Plan" shall mean, for any Plan Year, the Plan
                 if it would be a Top Heavy Plan under subsection 13.02(i)
                 hereof if the words "ninety percent (90%)" were substituted
                 for the words "sixty percent (60%)" in subsection 13.02(i)
                 hereof.

                 any of the following conditions exists.

                 (1)      If the Top Heavy Ratio for this Plan exceeds sixty
                          percent (60%) and this Plan is not part of any
                          Required Aggregation Group or Permissive Aggregation
                          Group of plans.

                 (2)      If this Plan is a part of a Required Aggregation
                          Group of plans, but not part of a Permissive
                          Aggregation Group, and the Top Heavy Ratio for the
                          Required Aggregation Group of plans exceeds sixty
                          percent (60%).

                 (3)      If this Plan is a part of a Required Aggregation
                          Group and also is a part of a Permissive Aggregation
                          Group of plans, and the Top Heavy Ratio for the
                          Permissive Aggregation Group exceeds sixty percent
                          (60%).

         (j)     "Top Heavy Ratio" shall mean as follows.

                 (1)      If the Employer maintains one (1) or more defined
                          contribution plans (including any simplified employee
                          pension plan under section 408(k) of the Code), and
                          the Employer has never maintained any defined benefit
                          plan which has covered or could cover a Participant
                          in this Plan, then the Top Heavy Ratio is a fraction,
                          the numerator of which is the sum of the account
                          balances of all Key Employees as of the Determination
                          Date (including any part of any account balance
                          distributed in the five (5) year period ending on the
                          Determination Date), and the denominator of which is
                          the sum of all account balances (including any part
                          of any account balance distributed in the five (5)
                          year period ending on the Determination Date) of all
                          Participants as of the Determination Date.  Both the
                          numerator and denominator of the Top Heavy Ratio are
                          adjusted to reflect any contribution which is due but
                          unpaid as of the Determination Date.

                 (2)      If the Employer maintains one (1) or more defined
                          contribution plans (including any simplified employee
                          pension plan under section 408(k) of the Code), and
                          the Employer maintains or has maintained one (1) or
                          more defined benefit pension plans which have covered
                          or could cover a Participant in this Plan, then the
                          Top Heavy Ratio is a fraction, the numerator of which
                          is the sum of account balances under the defined
                          contribution plans for all Key Employees and the
                          present value of accrued benefits under the defined
                          benefit pension plans for all Key Employees, and the
                          denominator of which is the sum of the account
                          balances under the defined contribution plans for all
                          Participants and the present value of accrued
                          benefits under the defined benefit pension plans for
                          all Participants.  Both the numerator and denominator
                          of the Top Heavy Ratio are adjusted for any
                          distribution of an account balance or an accrued
                          benefit made in the five (5) year period ending on
                          the Determination Date and any contribution due, but
                          unpaid, as of the Determination Date.

                 (3)      For purposes of the preceding subsections (1) and
                          (2), the value of account balances and the present
                          value of accrued benefits shall be determined as of
                          the most recent Top Heavy Valuation Date that falls
                          within or ends with the twelve (12) month period
                          ending on the Determination Date.  The account
                          balances and accrued benefits of a Participant who is
                          a Non-Key Employee, but who was a Key Employee in a
                          prior year, or who has not been credited with at
                          least one (1) Hour of Service with any Employer
                          maintaining the Plan at any time during the preceding
                          five (5) year period ending on the Determination
                          Date, shall be disregarded.  The calculation of the
                          Top Heavy Ratio, and the extent to which
                          distributions, rollovers and transfers are taken into
                          account shall be made in accordance with section 416
                          of the Code and the regulations thereunder.
                          Distributions shall include distributions under a
                          terminated plan which if it had not been terminated
                          would have been included in the Required Aggregation
                          Group.  When aggregating plans, the value of account
                          balances and accrued benefits shall be calculated
                          with reference to the determination dates that fall
                          within the same calendar year.

         (k)     "Top Heavy Valuation Date" shall mean, with respect to any
                 Plan Year, for this Plan, the Determination Date, and shall
                 mean with respect to any Plan Year for a defined benefit
                 pension plan maintained by the Employer, if any, the day
                 within the twelve (12) month period ending on the
                 determination date for such defined benefit pension plan as of
                 which the actuarial determination of the minimum funding
                 standard is calculated.

13.03    MINIMUM ALLOCATIONS IN SINGLE PLAN.

         Notwithstanding the provisions of Section 4.01 hereof, and before any
         contributions are allocated thereunder, minimum Employer Contributions
         shall be made and allocated pursuant to this section in a Plan Year in
         which the Plan is a Top Heavy Plan.

         (a)     The minimum Employer contribution for a Participant who is a
                 Non-Key Employee for any Plan Year in which the Plan is a Top
                 Heavy Plan shall not be less than the lesser of (i) three
                 percent (3%) of his Compensation or (ii) the percentage at
                 which Employer contributions (including salary deferral
                 contributions and Employer matching contributions) are made
                 for the Plan Year in respect of the Key Employee for whom such
                 percentage is the highest for the Plan Year, taking into
                 account such Key Employee's Compensation.

                 This minimum allocation shall be made even though, under other
                 Plan provisions, the Participant would not otherwise be
                 entitled to receive an allocation, or would have received a
                 lesser allocation for the Plan Year because of the following:

                 (1)      the Participant's failure to complete one thousand
                          (1,000) hours of Service.

                 (2)      the Participant's failure to make mandatory Employee
                          contributions, if any, required for participation in
                          the Plan; or





                                     13 - 4
<PAGE>   78
                 (3)      the Participant's Compensation was less than any
                          stated required amount.

                 This subsection shall not apply, however, to any Participant
                 who was not employed by the Employer on the last day of the
                 Plan Year.

                 In determining Employer contributions under this section,
                 contributions or benefits under Chapter 2 of the Code
                 (relating to taxes on self-employed income), Chapter 21 of the
                 Code (relating to the Federal Insurance Contribution Act) or
                 any other Federal or State laws (including Title II of the
                 Social Security Act) shall not be taken into account.  In
                 determining Employer contributions under this section for a
                 Non-Key Employee, salary deferral contributions and Employer
                 matching contributions needed to satisfy the actual
                 contribution percentage nondiscrimination test pursuant to
                 Section 3.04 or the actual deferral percentage
                 nondiscrimination test pursuant to Section 3.03 shall not be
                 taken into account.

                 The minimum allocations required hereunder (to the extent
                 required to be nonforfeitable under section 416(b) of the
                 Code) shall not be forfeitable under sections 411(a)(3)(B)
                 (regarding the suspension of benefits upon reemployment of a
                 retiree) or 411(a)(3)(D) (regarding withdrawal of mandatory
                 contributions) of the Code.

         (b)     Any Employer contributions and Forfeitures remaining
                 unallocated shall be allocated pursuant to the provisions of
                 Section 4.01 hereof; provided, however, that all allocations
                 under the Plan pursuant to Section 4.01 shall be determined
                 with respect to Compensation as that term is defined in
                 Section 1.10 hereof, but subject to the dollar limitation set
                 forth in subsection 13.02(a) hereof.

13.04    MINIMUM VESTING SCHEDULES.

         Notwithstanding the provisions of Section 8.01 hereof, the
         nonforfeitable interest of each Participant in his Employer Account in
         a Plan Year in which this Plan is a Top Heavy Plan shall be the vested
         percentage set forth in the following table (or the vested percentage
         determined in accordance with Section 8.01, if greater):

<TABLE>
<CAPTION>
                       Years of                           Vested
                   Vesting Service                      Percentage
                   ---------------                                
                     <S>                                  <C>
                     Less than 3                            0%
                      3 or more                            100
</TABLE>


         If the vesting schedules under the Plan shift in or out of the
         preceding schedule for any Plan Year because of a change in the Plan's
         Top Heavy status, then such shift shall be considered an amendment to
         the relevant vesting schedule and the election rule for Participants
         with three (3) or more years of Service set forth in Section 11.01(d)
         hereof shall apply.  Furthermore, any contributions that become
         nonforfeitable under this





                                     13 - 5
<PAGE>   79
         minimum vesting schedule for a Top Heavy Plan shall remain
         nonforfeitable if the Plan shifts out of Top Heavy status.

         The minimum vesting schedule applies to all benefits within the
         meaning of section 411(a)(7)(A) of the Code (except those attributable
         to voluntary Participant contributions, if any), including benefits
         accrued before the effective date of section 416 of the Code and
         benefits accrued before the Plan became a Top Heavy Plan.  Further, no
         reduction in nonforfeitable benefits may occur in the event the Plan's
         status as a Top Heavy Plan changes for any Plan Year.  However, this
         section does not apply to the account balances of any Participant who
         does not have an hour of Service after the Plan has initially become a
         Top Heavy Plan, and the nonforfeitable percentage and such
         Participant's Employer Account shall be determined without regard to
         this section.

13.05    SPECIAL LIMITATIONS AND ALLOCATION IN MULTIPLE PLANS.

         If for any Plan Year the Plan is a Top Heavy Plan, and the Employer
         maintains, or has ever maintained, a qualified defined benefit pension
         plan which is part of a Required or Permissive Aggregation Group, as
         appropriate, then the provisions of this section shall apply.

         If none of the Employer's plans are considered a Super Top Heavy Plan,
         then the Employer shall provide each Participant who would receive an
         allocation under Section 13.03 hereof and who is a participant also in
         the qualified defined benefit pension plan an allocation pursuant only
         to Section 13.03 hereof in lieu of accruing a benefit that year under
         the pension plan, but substituting in subsection 13.03(a) hereof the
         term "seven and one-half percent (7-1/2%)" for the term "three percent
         (3%)".  The Employer shall provide each Participant who would receive
         an allocation under Section 13.03 hereof, but who is not a participant
         also in the qualified defined benefit pension plan, an allocation
         pursuant to Section 13.03 hereof, but substituting in subsection (a)
         thereof the term "four percent (4%)" for the term "three percent
         (3%)".

         If any of the Employer's plans are considered a Super Top Heavy Plan,
         then in applying the limitations of Section 4.04 hereof, the term "one
         (1)" shall be substituted for the term "one and twenty-five hundredths
         (1.25)" in both the defined benefit fraction and the defined
         contribution fraction, as such terms are defined in Section 4.04
         hereof.  Furthermore, the Employer shall provide each Participant who
         would receive an allocation under Section 13.03 hereof and who is a
         participant also in the defined benefit pension plan an allocation
         pursuant only to Section 13.03 hereof in lieu of accruing a benefit
         that year under the pension plan, but substituting in subsection
         13.03(a) hereof the term "five percent (5%)" for the term "three
         percent (3%)".  The Employer shall provide each Participant who would
         receive an allocation under Section 13.03 hereof, but who is not a
         participant also in the defined benefit pension plan, an allocation
         only pursuant to Section 13.03 hereof.

                            MISCELLANEOUS PROVISIONS


14.01    ALLOCATION OF RESPONSIBILITY AMONG FIDUCIARIES FOR PLAN AND TRUST
         ADMINISTRATION.

         Each Fiduciary shall have only those specific powers, duties,
         responsibilities and obligations as are specifically given it under
         the Plan.  Each Fiduciary warrants that any directions given,
         information furnished, or action taken by it shall be in accordance
         with the provisions of the Plan authorizing or providing for such
         direction, information or action.  Furthermore, each Fiduciary may
         rely upon any such direction, information or action of any other
         Fiduciary as being proper under the Plan and is not required to
         inquire into the propriety of any such direction, information or
         action.  It is intended that each Fiduciary shall be responsible for
         the proper exercise of its own powers, duties, responsibilities and
         obligations under the Plan and shall not be responsible for any act or
         failure to act of another Fiduciary.  No Fiduciary guarantees the
         Trust Fund in any manner against investment loss or depreciation in
         asset value.

         Each Fiduciary shall discharge its duties set forth in the Plan solely
         in the interests of the Participants, Retired Participants and their
         Beneficiaries:

         (a)     for the exclusive purpose of:

                 (1)      providing benefits to such persons; and

                 (2)      defraying reasonable expenses of administering the 
                          Plan;

         (b)     with the care, skill, prudence and diligence under the
                 circumstances then prevailing that a prudent man acting in a
                 like capacity and familiar with such matters would use in the
                 conduct of an enterprise of a like character and with like
                 aims.

14.02    ALIENATION OR ASSIGNMENT OF BENEFITS (QDRO'S).

         The right of any Participant, Retired Participant or Beneficiary in
         any benefit or to any payment hereunder or to any segregated account
         may not be anticipated, conveyed, assigned, mortgaged or encumbered
         either by voluntary or involuntary action or by operation of law nor
         shall any such right or interest be in any manner subject to levy,
         attachment, execution, garnishment or any other seizure under legal,
         equitable or other process, except pursuant to a qualified domestic
         relations order, as defined in section 414(p) of the Code, or pursuant
         to a domestic relations order entered before January 1, 1985, under
         which payment of benefits under that order has commenced as of January
         1, 1985.  Otherwise, such interest in this Plan shall be payable only
         in accordance with the provisions hereof; provided, however, that
         distributions pursuant to a qualified domestic





                                     14 - 1
<PAGE>   81
         relations order may be made without regard to the age or employment
         status of the Participant.

         In the event that a Participant's benefits are garnished or attached
         by a court order which the Plan Administrator does not find to
         constitute such an order, the Plan Administrator may bring an action
         for declaratory judgment in a court of competent jurisdiction to
         determine the proper recipient of Plan benefits; during the pendency
         of such action, any benefits payable on behalf of the Participant may
         be paid into the court for distribution to the proper recipient
         pursuant to the judgment of the court.

14.03    HEADINGS.

         The headings and sub-headings of articles and sections are included
         solely for convenience of reference, and if there be any conflict
         between such headings and the text of the Plan, the text shall
         control.

14.04    CONSTRUCTION OF THE PLAN.

         In the construction of the Plan, the masculine gender shall include
         the feminine, the feminine gender shall include the masculine, and the
         singular shall include the plural, unless the context clearly
         indicates otherwise.

14.05    CORRECTION OF ERRORS.

         If any error or change in records results in any Participant, Retired
         Participant or Beneficiary receiving from the Plan more or less than
         he would have been entitled to receive had the records been correct or
         had the error not been made, the Plan Administrator, upon discovery of
         such error, shall correct the error by adjusting, as far as
         practicable, the payments in such a manner that the benefits to which
         such person was correctly entitled shall be paid.

14.06    LEGALLY INCOMPETENT.

         If any Participant, Retired Participant or Beneficiary is a minor or
         is otherwise legally incapable of personally receiving and giving a
         valid receipt for any payment due him hereunder, the Plan
         Administrator shall direct that such payment be made to the guardian
         or conservator of such person duly appointed by a court of competent
         jurisdiction.  Any payment so made shall be, to the extent of the
         payment, a complete discharge to the Employer and Trustee of any
         liabilities under the Plan.

14.07    SUCCESSOR ORGANIZATION.

         In the event of a merger or consolidation of any Employer into, or
         transfer of all or substantially all of its assets to, any legal
         entity, unincorporated business organization or corporation, provision
         may be made by such successor legal entity, unincorporated business
         organization or corporation for its election of the continuance of
         this Plan as to





                                     14 - 2
<PAGE>   82
         such successor entity.  Such successor shall, upon its election to
         continue this Plan, be substituted in place of the transferor Employer
         by an instrument duly authorizing such substitution and duly executed
         by such Employer and its successor.  Upon notice of such substitution,
         accompanied by a certified copy of the resolutions or other
         appropriate written instrument of the governing body of such Employer
         and its successor authorizing such substitution and delivered to the
         Trustee, the Trustee shall be authorized to recognize such successor
         in place of the transferor Employer.

14.08    MINIMUM BENEFIT IN SUCCESSOR PLAN.

         In the event of any merger or consolidation of the Plan with, or the
         transfer of assets or liabilities of the Plan to, any other qualified
         plan or trust, each Participant, Retired Participant and Beneficiary
         shall be entitled upon termination of the successor plan or trust
         immediately after the merger, consolidation or transfer to a benefit
         in an amount not less than he would have been entitled to receive if
         the Plan had terminated immediately before the merger, consolidation
         or transfer.

14.09    APPLICATION OF PLAN PROVISIONS.

         The provisions of the Plan shall apply only to Employees who terminate
         Service, or incur Breaks in Service, on or after the Effective Date.
         Any retirement plan rights and benefits of former Employees shall be
         determined in accordance with the provisions of any predecessor plan
         as in effect on the respective dates of termination of Service or
         Break in Service of such former Employees.  However, unless
         specifically otherwise stated in the Plan, the provisions of this
         amendment, restatement and continuation of the Plan shall apply only
         to Employees who have Service with the Employer on or after the
         effective date of this amendment, restatement and continuation of the
         Plan.

14.10    QUALIFICATION OF THE PLAN.

         The adoption of the Plan by each Employer is contingent on the receipt
         of a written, initial determination letter by the Internal Revenue
         Service that the Plan and Trust, with any modifications or amendments
         thereto requested by the Internal Revenue Service and agreed to by the
         Sponsor, constitute a qualified plan and trust under sections 401(a)
         and 501(a), respectively, of the Code.  In the event no such
         determination letter is received, no Participant, Retired Participant
         or Beneficiary shall have any right or claim to the assets of the
         Trust Fund or to any benefit under the Plan, all contributions made by
         the Employer and Participants in accordance with the terms of the Plan
         shall be returned to the respective parties, the Plan and Trust shall
         be terminated forthwith with respect to such Employer, and the Trustee
         shall be discharged from all obligation pursuant to adoption of the
         Plan by the Employer.

                               AMENDMENT NUMBER 1

                                     TO THE

                  TRUSTMARK NATIONAL BANK PROFIT SHARING PLAN



The Trustmark National Bank Profit Sharing Plan is hereby amended, effective
July 1, 1995, as follows:


1.   The last paragraph of Section 2.01 is amended to read as follows:

         Notwithstanding the above, the following classes of Employees shall be
         considered as excluded classes for purposes of the Plan, and Employees
         who are members of such classes shall not be eligible to participate
         in the plan:

         (a)  Employees who are active participants in the Trustmark
              National Bank Pension Plan who were also participants in the
              Canton Exchange Bank Employees Retirement Plan prior to its
              merger into the Trustmark National Bank Pension Plan;

         (b) Leased Employees.


2.   Subsection (b) of Section 3.01 is amended to read as follows:

         (b)  Employer Matching Contribution - Employer matching
              contributions shall be made in accordance with this subsection.

             (1)  Former Participants of the Rankin County Bank
                  401K Plan.  The Employer shall make an Employer matching
                  contribution on behalf of each Participant who was a former
                  participant in the Rankin County Bank 401K Plan on June 30,
                  1995, who has remained continuously employed by the Employer
                  since June 30, 1995 and who makes salary deferral
                  contributions during the Plan Year.  The amount of such
                  Employer matching contribution shall be one hundred percent
                  (100%) of the portion of the Participant's salary deferral
                  contributions for the Plan Year which does not exceed three
                  percent (3%) of the Participant's Compensation for the Plan
                  Year.  The Employer may, but is not required to, increase the
                  Employer matching contribution for such Participants for any
                  Plan Year by designating in writing a match formula for such
                  Plan Year that produces an Employer matching contribution for
                  each such Participant that is at least as large as the
                  Employer matching contribution produced by the formula
                  described above.

<PAGE>   86




             (2)  Other Participants.  The Employer may, but is
                  not required to, make an Employer matching contribution on
                  behalf of each Participant not described in subsection (1)
                  above who makes salary deferral contributions during the Plan
                  Year.  For any Plan Year in which the employer decides to
                  make such Employer matching contributions, the Committee
                  shall designate in writing the match formula to be used for
                  such Plan Year.

             (3)  General.  Notwithstanding the above, the
                  Employer shall not contribute amounts which (i) would, if
                  allocated to the Employer Account of Highly Compensated
                  Employees pursuant to Section 4.01(b), create excess
                  aggregate contributions (as defined in Section 3.04) or (ii)
                  are attributable to contributions which pursuant to Section
                  3.02(a), 3.03 or 3.04 are to be distributed to Employees.
                  The Employer matching contribution shall be subject to the
                  vesting schedule provided in Section 8.01 hereof and shall be
                  credited to Part II of the Participant's Employer Account.

3.   Subsection (a) of Section 4.01 is amended to read as follows:

         (a)  Employer Basic Contributions and Forfeitures.  Any
              Employer basic contributions made pursuant to Section 3.01(a)
              hereof and Forfeitures becoming available during the Plan Year
              shall be allocated on the last Allocation Date of the Plan Year
              to Part I of the Employer Account of each Participant entitled to
              share in such contributions and Forfeitures.  Only those
              Participants who complete at least one thousand (1,000) Hours of
              Service during the Plan Year and who are in one of the following
              categories for the Plan Year shall be eligible to share in the
              allocation of Employer basic contributions and Forfeitures:

             (a)  Participants who are employed on the last day
                  of the Plan Year or whose employment terminated on the last
                  day of the Plan Year; or

             (b)  Participants whose employment terminated during
                  the Plan Year due to retirement at or after Normal Retirement
                  Age, death or disability.

             Provided, however, that Participants who were former Participants
             in the Rankin County Bank 401K Plan on June 30, 1995 and who have
             remained continuously employed by the Employer since June 30,
             1995, shall not be eligible to share in the allocation of Employer
             basic contributions and Forfeitures.

<PAGE>   87

             Employer basic contributions and Forfeitures for the Plan Year
             shall be allocated to Part I of each such Participant's Employer
             Account in the proportion that such Participant's number of units
             as of the Allocation Date bears to the total number of units for
             all such Participants as of the Allocation Date.  For purposes of
             this allocation, one (1) unit shall be credited for each year of
             Vesting Service and one (1) unit will be credited for each full
             one hundred dollars ($100) of Compensation for the Plan Year.


4.   Paragraph (1) of subsection 6.03(d) is amended as follows:

         The reference to Section 6.04(c) in the fourth line of such paragraph
         (1) shall be changed to Section 6.03(c).


5.   Subsection (b) of Section 10.02 is amended by deleting the phrase "except
     as provided in Section 6.02 hereof" and substituting therefor the phrase
     "except as otherwise provided in the Plan."

Profit Sharing Plan is hereby executed by its duly authorized officer this 15th 
day of June, 1995.

                  TRUSTMARK NATIONAL BANK PROFIT SHARING PLAN



The Trustmark National Bank Profit Sharing Plan is hereby amended as follows:


1.   The first paragraph of subsection (a) of Section 3.02 is amended,

           Participant, a Participant may voluntarily elect to enter into a
           salary deferral agreement with the Employer.  Such salary deferral
           agreement shall serve to direct the Employer to contribute to the
           Participant's Personal Account, as salary deferral contributions, a
           portion of the amount which would otherwise be paid to the
           Participant as direct Compensation.  Salary deferral contributions
           shall be subject to the following restrictions:

          (1)  the amount of such contributions for any single pay
               period may not exceed two hundred eight dollars and thirty-three
               cents ($208.33) or fifteen percent of Compensation for the pay
               period, whichever is less;

          (2)  the amount of such contributions for any Plan Year
               may not exceed five thousand dollars.

          Provided, further, that such amount shall be subject also to the
          limitations on annual additions for the limitation year under Section

                               AMENDMENT NUMBER 3

                                     TO THE

                  TRUSTMARK NATIONAL BANK PROFIT SHARING PLAN



The Trustmark National Bank Profit Sharing Plan is hereby amended, effective
January 1, 1989, as follows:


1.  Section 1.21 is amended by adding the following immediately before the
    last paragraph of the Section:

        For purposes of this Section, an individual is in the top-paid group
        for any year if such individual is in the group consisting of the top
        twenty percent (20%) of the employees when ranked on the basis of
        compensation paid during such year.

2.  Section 3.03 is amended in its entirety to read as follows:

    3.03    COVERAGE AND DISCRIMINATION REQUIREMENTS.

            Salary deferral contributions for any Plan Year after December 31, 
            1986 shall satisfy one (1) of the following tests:

            (a)      the average deferral percentage for the Highly Compensated
                     Employees who are eligible to participate in the Plan for 
                     the Plan Year shall not be more than the average deferral
                     percentage of the Non-highly Compensated Employees who are
                     eligible to participate in the Plan for the Plan Year
                     multiplied by one and twenty-five hundredths (1.25); or

            (b)      the excess of the average deferral percentage for the 
                     Highly Compensated Employees who are eligible to
                     participate in the Plan for the Plan Year over that of the
                     Non-highly Compensated Employees who are eligible to
                     participate in the Plan for the Plan Year shall not be
                     more than two percent (2%), nor shall the average deferral
                     percentage for such Highly Compensated Employees be more
                     than that of such Non-highly Compensated Employees
                     multiplied by two (2).

            For purposes of this Section, the term "average deferral
            percentage" for a group of Employees shall mean the average of the
            percentages, calculated separately for each Employee in the group,
            of the amount of salary deferral contributions and, if applicable,
            qualified nonelective contributions and Qualified Matching
            Contributions, made on behalf of the Employee for a Plan Year, to
            the amount of the Employee's Compensation for such Plan Year (the
            "deferral percentage").  Qualified nonelective contributions and
            Qualified Matching Contributions may be included in the calculation
            of deferral percentages only if the conditions described in section
            1.401(k)-1(b)(5) of the regulations are satisfied.  For purposes of
            calculating the
<PAGE>   90
            average deferral percentage, eligible Employees with no salary
            deferral contributions or, if applicable, qualified nonelective
            contributions or Qualified Matching Contributions, shall be
            included in such calculation with deferral percentages of zero
            percent (0%).  For purposes of determining the deferral percentage
            of a Participant who is a five percent (5%) owner of the Employer
            or one of the top ten (10) highest paid Highly Compensated
            Employees, the amount of contributions and Compensation of such
            Participant shall include the contributions and Compensation of
            family members (as described in Code section 414(q)(6)(B)) to the
            extent required by regulations.  Family members who are required to
            be aggregated with respect to such Highly Compensated Employees
            shall be disregarded as separate Employees in determining the
            average deferral percentage both for eligible Employees who are
            Highly Compensated Employees and for eligible Employees who are
            Non-highly Compensated Employees.  For purposes of this Section,
            the following rules, relating to aggregation of plans, shall apply:

            (c)      All salary deferral contributions that are made under this
                     Plan and any other plan that is aggregated with this Plan
                     for purposes of sections 401(a)(4) and 410(b) (other than
                     section 410(b)(2)(A)(ii)) of the Code shall be treated as
                     made under a single plan.

            (d)      If this Plan is permissively aggregated with any other 
                     plan or plans for purposes of section 401(k) of the Code,
                     such aggregated plans must satisfy sections 401(a)(4) and  
                     410(b) of the Code as though they were a single plan.

            (e)      The deferral percentage for any eligible Employee who is a
                     Highly Compensated Employee and who is eligible to make
                     salary deferral contributions under this Plan and any
                     other plan maintained by the Employer (other than plans
                     that may not be permissively aggregated) shall be
                     determined as if all such  plans were a single plan.

            A salary deferral contribution shall be considered to have been
            made with respect to a Plan Year if it (i) is allocated to the
            account of a Participant as of any date within that Plan Year and
            (ii) relates to Compensation that either would have been received
            by the Participant in the Plan Year but for the Participant's
            election to defer under the arrangement, or is attributable to
            services performed by the Participant in the Plan Year and, but for
            the Participant's election to defer, would have been received by
            the Participant within two and one-half (2-1/2) months after the
            close of the Plan Year.  A contribution shall be considered
            allocated as of any date within a Plan Year if the following
            conditions are met:

            (f)      such allocation is not dependent upon participation in the
                     Plan as of any date subsequent to the allocation date,

            (g)      the Employer contributions in addition to those 
                     attributable to salary deferral contributions are actually
                     made to the Plan no later than the end of the period
                     described in Code section 404(a)(6) applicable to the
                     taxable year with or within which the Plan Year ends, and

<PAGE>   91
            (h)      the Employer contributions attributable to salary deferrals
                     are actually made to the Plan no later than the end of the
                     twelve (12) month period immediately following the end of 
                     the Plan Year to which the contribution relates.

            Excess contributions shall mean, with respect to any Plan Year, the
            excess of:

            (i)      The aggregate amount of contributions actually taken into
                     account in computing the average deferral percentage of 
                     Highly Compensated Employees for such Plan Year as 
                     described above, over

            (j)      The maximum amount of such contributions permitted by the
                     average deferral percentage test (determined by reducing
                     contributions made on behalf of Highly Compensated 
                     
            Employees in order of the average deferral percentages, beginning
            with the highest of such percentages).

            Provided, that the amount of any such excess contributions to be
            distributed pursuant to this Section 3.03 with respect to a
            Participant for a Plan Year shall be reduced by any salary deferral
            contributions in excess of the dollar limit specified in Section
            3.02(a) hereof which are previously distributed to such Participant
            for his taxable year ending with or within such Plan Year.  In
            addition, the amount of such excess contribution of a Highly
            Compensated Employee whose average deferral percentage is
            determined under the family aggregation rules, shall be allocated
            among the family members in proportion to the salary deferral
            contributions of each family member that are combined to    
            determine the combined average deferral percentage.

            Excess contributions shall, if required by law or regulations, be
            adjusted for any Income up to the date of distribution.  The Income
            allocable to such excess contribution shall be equal to the sum of
            (i) the allocable Income for the Plan Year and (ii) the allocable
            Income for the period between the end of the Plan Year and the date
            of distribution.  The Income allocable to excess contributions for
            such periods is determined in a manner analogous to the above
            allocation of Income to excess deferrals, but basing the allocation
            on excess contributions and the Income allocable to salary deferral 
            contributions.

            If, for any Plan Year, salary deferral contributions are made with
            respect to the Highly Compensated Employees in excess of that
            permissible under subsections (a) and (b) of this Section 3.03, the
            Committee shall, before the end of the Plan Year following the Plan
            Year during which such excess contribution occurs, distribute the
            amount of such excess to the Participant on whose behalf the
            contribution was made.

            Any distributions made hereunder shall be made to Highly Compensated
            Employees on the basis of the respective portions of the excess
            contributions attributable to each of such Employees.

            The tests described in this Section and the corrective measures for
            insuring passage of such tests may be performed in any manner
            permitted under section 401(k) of the Code, the regulations
            thereunder and any other related rulings or pronouncements issued
            by the Secretary of the Treasury or the Internal Revenue Service.

3.  Section 3.04 is amended in its entirety to read as follows:

    3.04    DISCRIMINATION REQUIREMENTS FOR OTHER CONTRIBUTIONS.

            The Plan must satisfy the nondiscrimination requirements of section
            401(m) of the Code and the regulations issued thereunder, which are
            incorporated herein by reference.  The Plan shall satisfy such
            requirements if, with respect to any Plan Year, either of the
            following alternative conditions are met:

            (a)      the average contribution percentage for eligible Highly
                     Compensated Employees is not greater than the average
                     contribution percentage for eligible Non-highly Compensated
                     Employees, multiplied by one and twenty-five hundredths
                     (1.25).

            (b)      the excess of the average contribution percentage for 
                     eligible Highly Compensated Employees over that of
                     eligible Non-highly Compensated Employees is not more than
                     two percent (2%), nor is the average contribution
                     percentage for such Highly Compensated Employees more than
                     that of such Non-highly Compensated Employees, multiplied 
                     by two (2).
    
            For purposes of this Section, "Eligible Employee" shall mean any
            Employee who is eligible to make or be credited with contribution
            percentage amounts.  Contribution percentage amounts shall mean
            Employer matching contributions, voluntary after-tax contributions
            and (subject to the conditions hereinafter enumerated and to the
            extent taken into account in the calculation of average
            contribution percentages) salary deferral contributions, qualified
            nonelective contributions and Qualified Matching Contributions. 
            The Employer may elect to include salary deferral contributions and
            qualified nonelective contributions, and must include Qualified
            Matching Contributions, to the extent such contributions are not
            included in the tests described in Section 3.03 hereof.  Salary
            deferral contributions and qualified nonelective contributions may
            be included only if the conditions described in section
            1.401(m)-1(b)(5) and 1.401(k)-1(g)(13) of the regulations are
            satisfied.  The term "average contribution percentage" for a group
            of Eligible Employees shall mean the average of the ratios,
            calculated separately for each Eligible Employee in the group, of
            the contribution percentage amounts made on behalf of an Eligible
            Employee during the Plan Year to that Eligible Employee's
            Compensation for such Plan Year (the "contribution percentage"). 
            For purposes of calculating the average contribution percentage,
            Eligible Employees with no contribution percentage amounts shall be
            included in such calculation with contribution percentages of zero
            percent (0%). For purposes of determining the contribution
            percentage of a Participant who is a five percent (5%) owner of the
            Employer or one of the top ten (10) highest paid Highly Compensated
            Employees, the amount of voluntary after-tax contributions,
            Employer matching contributions and Compensation of such
            Participant shall include the voluntary after-tax
            contributions, Employer matching contributions and

<PAGE>   93

            Compensation of family members (as described in Code section
            414(q)(6)(B)).  Family members, with respect to Highly Compensated
            Employees, shall be disregarded as separate Employees in determining
            the contribution percentage both for Eligible Employees who are
            Non-highly Compensated Employees and for Eligible Employees who are
            Highly Compensated Employees.  For purposes of this Section, the
            following rules, relating to aggregation of plans, shall apply:

            (c)      All contribution percentage amounts that are made under 
                     this Plan and any other plan that is aggregated with this
                     Plan for purposes of sections 401(a)(4) and 410(b) (other
                     than section 410(b)(2)(A)(ii)) of the Code shall be
                     treated as made under a single plan.
    
            (d)      If this Plan is permissively aggregated with any other 
                     plan or plans for purposes of section 401(m) of the Code,
                     such aggregated plans must satisfy sections 401(a)(4) and
                     410(b) of the Code as though they were a single plan.
    
            (e)      The contribution percentage for any Eligible Employee who 
                     is a Highly Compensated Employee and who is eligible to
                     have contribution percentage amounts credited to him under
                     this Plan and any other plan maintained by the Employer
                     (other than plans that may not be permissively aggregated)
                     shall be determined as if all such plans were a single
                     plan.
    
            "Excess aggregate contributions", plus any Income allocable
            thereto, shall be forfeited, if forfeitable, or if not forfeitable,
            distributed no later than the last day of each Plan Year to
            Participants to whose accounts such excess aggregate contributions
            were allocated for the preceding Plan Year.  Excess aggregate
            contributions shall be allocated to Participants who are subject to
            the family member aggregation rules of section 414(q)(6) of the
            Code in proportion to the Employee matching contributions of each
            family member that are combined to determine the combined average
            contribution percentage.  Excess aggregate contributions shall be
            treated as annual additions, as defined in Section 4.04, hereof.
    
            "Excess aggregate contributions" shall mean, with respect to any 
            Plan Year, the excess of:

            (f)      The aggregate contribution percentage amounts taken into
                     account in computing the numerator of the contribution
                     percentage actually made on behalf of Highly Compensated
                     Employees for such Plan Year, over
    
            (g)      The maximum contribution percentage amounts permitted by 
                     the average contribution percentage test (determined by
                     reducing contributions made on behalf of Highly
                     Compensated Employees in order of their contribution
                     percentages beginning with the highest of such
                     percentages).
    
            Such determination shall be made after first determining excess
            elective deferrals pursuant to Section 3.02 and then determining 
            excess contributions pursuant to Section 3.03 hereof.
<PAGE>   94

            Excess aggregate contributions shall, if required by law or
            regulations, be adjusted for any Income up to the date of
            distribution. The Income allocable to excess aggregate
            contributions for such period is determined in a manner analogous
            to the above allocation of Income to excess deferrals, but basing
            the allocation on excess aggregate contributions and the Income
            allocable to Employer matching contributions and Employee
            voluntary after-tax contributions.
    
            Forfeitures of excess aggregate contributions shall be applied to
            reduce Employer contributions.

            The tests described in this Section and the corrective measures for
            insuring passage of such tests may be performed in any manner
            permitted under section 401(m) of the Code, the regulations
            thereunder and any other related rulings or pronouncements issued
            by the Secretary of the Treasury or the Internal Revenue
            Service.
    
4.  Section 14.10 is amended in its entirety to read as follows:

    14.10   QUALIFICATION OF THE PLAN.

            The adoption of the Plan by each Employer is contingent on the
            receipt of a written, initial determination letter by the Internal
            Revenue Service that the Plan and Trust, with any modifications or
            amendments thereto requested by the Internal Revenue Service and
            agreed to by the Sponsor, constitute a qualified plan and trust
            under sections 401(a) and 501(a), respectively, of the Code.  In
            the event no such determination letter is received, no Participant,
            Retired Participant or Beneficiary shall have any right or claim to
            the assets of the Trust Fund or to any benefit under the Plan, all
            contributions made by the Employer and Participants in accordance
            with the terms of the Plan shall be returned to the respective
            parties within one (1) year of the date of denial of qualification,
            the Plan and Trust shall be terminated forthwith with respect to
            such Employer, and the Trustee shall be discharged from all
            obligation pursuant to adoption of the Plan by the Employer.


IN WITNESS WHEREOF, this Amendment Number 3 to the Trustmark National Bank
Profit Sharing Plan is hereby executed by its duly authorized officer this 28th
day of December, 1995.
