ITEM 4.  DESCRIPTION OF SECURITIES.

         Not Applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not Applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         (a) Section 145(a) of the Delaware General Corporation Law (the "DGCL")
provides that a corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(collectively, a "Proceeding") (other than an action by or in the right of the
corporation) by reason of the fact that he or she is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding if such person acted in good
faith and in a manner he or she reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his or her conduct was
unlawful.

         Section 145(b) of the DGCL provides that a corporation may indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against such expenses
actually and reasonably incurred by him or her in connection with the defense or
settlement of such action or suit if he or she acted under similar standards,
except that no indemnification may be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnification
for such expenses which the court shall deem proper.


                                      -4-

<PAGE>   5

         Further, Section 145(c) of the DGCL provides that, to the extent a
director or officer of a corporation has been successful on the merits or
otherwise in the defense of any action, suit or proceeding referred to above or
in the defense of any claim, issue or matter therein, he or she shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him or her in connection therewith.

         Section 145(f) of the DGCL provides that the statutory provisions on
indemnification are not exclusive of indemnification provided pursuant to, among
other things, the bylaws or indemnification agreements. Trinity's Bylaws contain
provisions regarding the indemnification of directors and officers of Trinity.
Article VI of Trinity's Bylaws provides for the indemnification of Trinity's
officers and directors to substantially the same extent permitted by the DGCL.

         The indemnification described above (unless ordered by a court) shall
be paid by Trinity unless a determination is made (i) by Trinity's Board of
Directors by a majority vote of a quorum consisting of directors who were not
parties to such Proceeding, or (ii) if such a quorum is not obtainable, or, even
if obtainable a quorum of disinterested directors so directs, by independent
legal counsel in a written opinion, or (iii) by Trinity's stockholders, that
indemnification of the director, officer, employee or agent is not proper in the
circumstances because he has not met the applicable standard of conduct set
forth above.

         Article VI of Trinity's Bylaws provides that costs, charges and
expenses (including attorneys' fees) incurred by a person seeking
indemnification under Article VI of Trinity's Bylaws in defending a Proceeding
shall be paid by Trinity in advance of the final disposition of such Proceeding;
provided, however, that the payment of such costs, charges and expenses incurred
by a director or officer in his capacity as a director or officer (and not in
any other capacity in which service was or is rendered by such person while a
director or officer) in advance of the final disposition of such Proceeding
shall be made only upon receipt of an undertaking by or on behalf of the
director or officer to repay all amounts so advanced in the event that it shall
ultimately be determined that such director or officer is not entitled to be
indemnified by Trinity. Such costs, charges and expenses incurred by other
employees and agents may be so paid upon such terms and conditions, if any, as
Trinity's Board of Directors deems appropriate. The Board of Directors may, upon
approval of such director, officer, employee or agent of Trinity, authorize
Trinity's counsel to represent such person in any Proceeding, whether or not
Trinity is a party to such Proceeding.

         Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
but excludes specifically liability for any (i) breach of the director's duty of
loyalty to the corporation or its stockholders, (ii) acts or omissions not in
good faith or involving intentional misconduct or a knowing violation of law,
(iii) payments of unlawful dividends or unlawful stock repurchases or
redemptions, or (iv) transactions from which the director derived an improper
personal benefit. The provision does not limit equitable remedies, such as an
injunction or rescission for breach of a director's fiduciary duty of care.


                                      -5-

<PAGE>   6

         Trinity's Certificate of Incorporation contains a provision eliminating
the personal liability of a director from breaches of fiduciary duty, subject to
the exceptions described above.

         (b) Trinity has entered into Indemnity Agreements with all of its
directors and officers that establish contract rights to indemnification
substantially similar to the rights to indemnification provided for in Trinity's
Bylaws.

         amendments thereto, to the Internal Revenue Service (the "IRS") in a

         in order to qualify the plan under Section 401 of the Internal Revenue
         Code.

ITEM 9.  UNDERTAKINGS.

(a)      Trinity 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;


                                      -6-

<PAGE>   7

             (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, represent a fundamental
                   change in the information set forth in this Registration
                   Statement; and

             (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 information required to be included in a post-effective amendment by
     those paragraphs is contained in periodic reports filed with or furnished
     to the Commission by Trinity pursuant to Section 13 or Section 15(d) of the
     Exchange Act that are incorporated by reference in the registration
     statement.

     (2) That, for the purpose of determining any liability under the Securities
     Act, 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 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) Trinity hereby undertakes that, for purposes of determining any liability
under the Securities Act, each filing of Trinity's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Exchange Act) 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
may be permitted to directors, officers and controlling persons of Trinity
pursuant to the foregoing provisions, or otherwise, Trinity has been advised
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by Trinity of expenses incurred or paid by a director, officer or
controlling person of Trinity in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, Trinity 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 of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

                                   ARTICLE II

              DEFINITIONS, CONSTRUCTION, ADOPTION AND APPLICABILITY

2.01     Definitions

         The following words and phrases, when used herein, unless their context
         clearly indicates otherwise, shall have the following respective
         meanings:

         (a) ADDITIONS: With respect to each year, the sum of the following
             amounts allocated on behalf of a Participant for a Year: (i) all
             Employer contributions; (ii) all Forfeitures; and (iii) all
             Employee contributions. Except to the extent provided in Treasury
             regulations, Additions include "excess contributions" (as defined
             in Code Section 401(k)(8)(B)) and "excess aggregate contributions"
             (as defined in Code section 401(m)(6)(B)), irrespective of whether
             the Plan distributes or forfeits such excess amounts. "Excess
             deferrals" (as defined in Code section 402(g)) are not Additions
             unless distributed after the correction period described in Code
             Section 402(g). Additions also include excess amounts reapplied to
             reduce Employer contributions. Amounts allocated to an individual
             medical account (as defined in Code Section 415(l)(2)) included as
             part of a defined benefit plan maintained by the Employer are
             Additions.

         (b) AFFILIATE: Any corporation (other than an Employer) which is
             included within a controlled group of corporations (as defined in
             Section 414(b) of the Code) which includes an Employer; any trade
             or business (other than an Employer), whether or not incorporated,
             which is under common control (as defined in Section 414(c) of the
             Code) with an Employer; any organization (other than an Employer),
             whether or not incorporated, which is a member of an affiliated
             service group (as defined in Section 414(m) of the Code) which
             includes an Employer; and any other entity required to be
             aggregated with an Employer pursuant to regulations under Section
             414(o) of the Code.

         (c) AUTHORIZED LEAVE OF ABSENCE: Any absence (including military leave)
             authorized by an Employer under the Employer's standard personnel
             practices, uniformly applied and in accordance with applicable
             Federal law (other than ERISA); provided however that no absence
             shall be considered an Authorized Leave of Absence unless the
             Employee returns to employment immediately (in the case of


                                       2

<PAGE>   3

             military leave, within the 90-day period after his discharge or
             release or within the period prescribed by applicable law,
             whichever is longer) upon the expiration of such absence. An
             absence due to service in the Armed Forces of the United States
             shall be considered an Authorized Leave of Absence provided that
             the absence is caused by war or other emergency, or provided that
             the Employee is required to serve under the laws of conscription in
             time of peace.

         (d) BENEFICIARY: A person or persons (natural or otherwise) designated
             by a Participant or Former Participant in accordance with the
             provisions of Section 6.05 to receive any death benefit which shall
             be payable under this Plan.

         (e) CODE: The Internal Revenue Code of 1986, as amended from time to
             time.

         (f) COMMITTEE: The persons appointed under the provisions of Article
             VIII to administer the Plan.

         (g) COMPANY: TRINITY INDUSTRIES, INC., a corporation organized and
             existing under the laws of the State of Delaware, or its successor
             or successors.

         (h) COMPENSATION: The total of all amounts paid to a Participant by the
             Employer for personal services as reported on the Participant's
             Federal Income Tax Withholding Statement (Form W-2) plus any salary
             reduction amounts described in Section 4.02 hereof and any amounts
             not included in the Participant's gross income pursuant to Section
             125 of the Code, but excluding (i) any other contributions made
             under this Plan or any other plan of deferred compensation, (ii)
             tuition reimbursement payments, (iii) moving expense payments, (iv)
             excess life insurance imputed income, (v) income from nonqualified
             stock options, (vi) automobile allowance payments, (vii) medical
             allowance payments, (viii) safe driving bonuses, (ix) employee
             awards, (x) lodging allowance payments, (xi) tool allowance
             payments, (xii) road expense reimbursement payments, (xiii)
             commuting allowance payments, (xiv) meal allowance payments, (xv)
             third-party sick pay, (xvi) attendance/safety bonuses; (xvii)
             travel allowances, (xviii) company automobile; (xix) executive
             perquisites; and (xx) such other similar amounts as the Committee
             may from time to time exclude in its sole discretion; provided,
             however, that for purposes of determining benefits hereunder, the
             total Compensation of a Participant to be taken into account for a
             given Year shall not exceed $150,000.00 (as automatically increased
             in accordance with Treasury Department regulations to reflect cost
             of living adjustments). Notwithstanding the preceding, for purposes
             of discrimination testing under Sections 401(a)(4), 401(k), 401(m)
             and 410(b) of the Code, Compensation shall be determined without
             excluding the items described in clauses (ii) through (iv), (vi)
             through (xi) and (xiii) through (xix) of this paragraph.

         (i) DISABILITY: A physical or mental condition which, in the judgment
             of the Committee, totally and presumably permanently prevents a
             Participant from engaging in any substantial or gainful employment.
             Determinations of Disability shall be made on the basis of
             standards applied uniformly to all Participants.

             1999, the date on which the provisions of this amended and restated
             Plan become effective.

         (k) ELAPSED-TIME EMPLOYMENT: With respect to an Employee, the period
             beginning on his Employment Commencement Date (or Re-employment
             Commencement Date, as the case may be) and ending on the date of
             his Severance from Service. Such period shall be determined without

             Employment completed with an Affiliate or a Participating Employer

             employees constitute less than twenty percent (20%) of the
             Employer's non-highly compensated work force within the meaning of
             Code Section 414(n)(5)(C)(ii), the term "Employee" shall not
             include leased employees covered by a plan described in Code
             Section 414(n)(5) unless otherwise provided by the terms of this
             Plan. Notwithstanding the preceding, the term "Employee" shall not
             include any individual who is designated as an "independent
             contractor" by the Employer, even if the status of such individual
             subsequently is changed from that of an independent contractor to
             that of an employee as a result of administrative or legal
             proceedings.

             414(q). A Participant or Former Participant is considered a Highly
             Compensated Employee if:

             (1)  during the Plan Year (the "Determination Year"), during the
                  twelve month period immediately preceding the Determination
                  Year or, if the Employer elects, during the calendar year
                  ending with or within the Determination Year (the "Look Back
                  Year"), the Participant or Former Participant was at any time
                  a "five percent owner" as defined in Code Section
                  416(i)(1)(A)(iii); or

             (2)  for the preceding Plan Year, the Participant or Former
                  Participant had Compensation from the Employer in excess of
                  $80,000 (as automatically increased in accordance with
                  Treasury Department regulations).

             The Committee shall determine which Participants or Former
             Participants are Highly Compensated Employees in a manner
             consistent with Code Section 414(q) and the regulations promulgated
             thereunder. The Employer may make a calendar year election to
             determine the Highly Compensated Employees for the Look Back Year,
             as described above and as prescribed by the applicable Treasury
             Department regulations, provided that a calendar year election must
             apply to all employee pension benefit plans of the Employer.

             A Former Participant who separated from Service, or is deemed to
             have separated from Service under the applicable Treasury
             Department regulations, prior to the Plan Year, who performs no
             Service for the Employer during the Plan Year and who was



                                       5

<PAGE>   6

             a Highly Compensated Employee either for the "separation year " or
             any Plan Year ending on or after such Former Participant attained
             age fifty-five (55) is considered a Highly Compensated Employee.
             For purposes of this paragraph (u), "separation year" means the
             Plan Year during which the Employee separates from Service with the
             Employer.

         (v) HOUR OF EMPLOYMENT: Each hour (i) for which an Employee is on an
             Authorized Leave of Absence or is directly or indirectly paid or
             entitled to payment by his Employer for the performance of duties
             or for reasons other than the performance of duties, or (ii) for
             which back-pay (irrespective of mitigation of damages) has been
             either awarded or agreed to by the Employer. In the case of clause
             (i) above, each such Hour of Employment shall, in general, be
             credited for the computation period in which the duties were
             performed, or to which payments or entitlements to payments relate
             (in cases in which Hours of Employment are credited for periods in
             which duties are not performed.) In the case of clause (ii) above,
             each such Hour of Employment shall, in general, be credited for the
             computation period to which the agreement or award pertains.
             Notwithstanding any provision to the contrary herein contained, no
             Employee shall be credited with an Hour of Employment under both
             clauses (i) and (ii) above. In determining the number of Hours of
             Employment to be credited to an Employee in the case of a payment
             which is made or due to an Employee under the provisions of clause
             (i) above, for a period during which services were not performed
             (including a payment made by application of clause (ii) for a
             period also covered by clause (i) during which services were not
             performed), and the computation period(s) to which Hours of
             Employment shall be credited, the Committee shall apply the rules
             set forth in United States Department of Labor Regulationsss.
             2530.200b-2(b) and (c), which rules are incorporated into and made
             a part of this Plan by reference. Nothing in this paragraph shall
             be construed as denying an Employee credit for an Hour of
             Employment which he is required to receive under any Federal law,
             the nature and extent of which credit shall be determined by such
             Federal law.

             Hours of Employment shall be determined from records maintained by
             each Employer; provided, however, that an Employer may elect to
             determine Hours of Employment for any classification of Employees
             which is reasonable, nondiscriminatory and consistently applied, on
             the basis that Hours of Employment include forty-five (45) Hours of
             Employment for each week or portion thereof during which an
             Employee is credited with one (1) Hour of Employment. In
             determining the equivalent number of Hours of Employment to be
             credited to an Employee in the case of a payment made or due under
             paragraph (1) above, when the payment is not calculated on the
             basis of units of time, the Committee shall apply the rules set
             forth in United States Department of Labor Regulations Section
             2530.200b-2(b)(2) and (3). If such a payment is calculated on the
             basis of units of time, which units are greater than the period of
             employment used in this equivalency formula, the Employee shall be
             credited with the number of Hours of Employment included in the
             periods of employment which, in the course of the Employee's
             regular work schedule, would be included in the unit or units of
             time on the basis of which the payment is calculated.

             the Employer in accordance with Section 416(i)(A)(iii) of the Code,

         The masculine gender, where appearing in the Plan, shall be deemed to
         include the feminine gender, unless the context clearly indicates to
         the contrary. The words "hereof," "herein," "hereunder" and other
         similar compounds of the word "here" shall mean and refer to the entire
         Plan and not to any particular provision or Section.

2.03     Adoption by Others

         Any Affiliate of the Company may adopt this Plan and thereby become an
         Employer; provided, however, that the Board of Directors of the Company
         approves such adoption; provided, further, that the administrative

3.01     Participation

         Subject to the provisions of Section 3.03 hereof and except for any
         Employee (i) who is a member of a collective bargaining unit, the
         recognized representative of which has not agreed to Participation in
         the Plan by its members, (ii) who is a nonresident alien and receives
         no earned income (within the meaning of Section 911(d)(2) of the Code)
         from the Employer which constitutes income from United States sources
         (within the meaning of Section 861(a)(3) of the Code), (iii) who is a
         leased employee within the meaning of Section 414(n)(2) of the Code,
         (iv) who is classified as a project status employee, or (v) who is an
         employee or within a class of employees designated on Appendix I
         attached hereto, an Employee shall become a Participant in this Plan as
         follows:

         (a) Any Employee included under the provisions of the Prior Plan as of
             January 1, 1999 shall continue to participate in accordance with
             the provisions of this Plan.

         (b) The Participation of any Employee who is eligible to become a
             Participant on or after January 1, 1999, shall commence on the
             first day of the month immediately following the sixty (60)-day

         Under no circumstances shall an individual become a Participant prior
         to the date on which he is classified as an active Employee. An active
         Participant who incurs a Severance from Service and who is subsequently
         re-employed by an Employer shall immediately reenter the Plan as an
         active Participant on his Re-employment Commencement Date, with such
         Participant's prior salary reduction agreement to continue to apply
         until amended, terminated or suspended in accordance with the
         provisions of Section 4.02 hereof. In the event that a Participant
         shall either become a member of a collective bargaining unit described
         above, or otherwise be excluded from Participation pursuant to the
         first paragraph of this Section 3.01, his Participation shall thereupon
         cease but he shall continue to accrue Service hereunder during the
         period of his continued employment with the Employer. For purposes of
         this Section 3.01, an Employee shall be credited with Service for
         periods of employment with an Affiliate (determined as if such
         Affiliate were an Employer), but shall not commence Participation
         hereunder prior to the date on which he commences employment with an
         Employer. The term "active Participant" shall mean any Employee
         currently participating in the Plan who has not incurred a Severance
         from Service.

         The Committee is hereby authorized to identify, in writing on Appendix
         I, those employees or classes of employees employed at a location of an
         Employer who are not eligible to participate in the Plan. The Committee
         is further authorized and directed to revise Appendix I, or to have
         Appendix I revised by the appropriate person designated by the
         Committee, to reflect any necessary additions and deletions thereto as
         soon as administratively possible following such identification by the
         Committee. Revisions to Appendix I shall require the adoption of a Plan
         amendment and, notwithstanding the provisions of Section 10.01 hereof,
         the Board of Directors of the Company hereby delegates to the Committee
         (or the Committee's authorized representative) the authority to execute

                  (3)      if such Employee incurs a Break in Service (as
                           defined in paragraph (d) of this Section and
                           determined as if such Affiliate were a Participating
                           Employer) prior to his commencement of employment
                           with the Participating Employer or return to the
                           employment of the Participating Employer, then the
                           amount of such Employee's service attributable to the
                           period of his employment with such Affiliate shall be

                           such Affiliate were a Participating Employer; and

                  (2)      if such Participant incurs a Break in Service (as
                           defined in paragraph (d) of this Section and
                           determined as if such Affiliate were a Participating
                           Employer) prior to his commencement of employment
                           with the Affiliate or return to the employment of the
                           Affiliate, then the amount of such Participant's
                           Service attributable to his prior period of
                           employment with the Participating Employer shall be

                  hereof, such Participant shall receive no benefits under this

                  Employers.

         (d)      Break in Service--An Employee who incurs a Severance from

                  shall return to the employment of a Participating Employer by
                  completing at least one (1) Hour of Employment


                                       11

<PAGE>   12

                  within such twelve (12)-month period, then such Employee will
                  not have a Break in Service and shall receive Service for the
                  period beginning on the date of his Severance from Service and
                  ending on the date of his re-employment; provided, however,
                  that in the case of an Employee who is absent from the
                  employment of the Participating Employers for a reason
                  specified in Section 2.01(jj)(1)(ii) hereof and who, prior to
                  the first anniversary of the first date of such absence incurs
                  a Severance from Service for a reason specified in section
                  2.01(jj)(1)(i) hereof, such Employee shall receive Service
                  only if he completes at least one (1) Hour of Employment
                  within the twelve (12)-month period beginning on the first
                  date of such absence and shall receive such Service only for
                  the period beginning on the first day of such absence and
                  ending on the date of his re-employment. Upon incurring a
                  Break in Service, an Employee's rights and benefits under the
                  Plan shall be determined in accordance with his Service at the
                  time of the Break in Service. For a Participant who, at the
                  time of a Break in Service, satisfied any requirements of this
                  Plan for vested benefits, his pre-break Service shall, upon
                  his Re-employment Commencement Date, be restored in
                  determining his rights and benefits under the Plan. For an
                  Employee who, at the time of a Break in Service, had not
                  fulfilled such requirements, periods of pre-break Service
                  shall, upon his Re-employment Commencement Date, be restored
                  only if the consecutive periods of Break in Service were less
                  than the greater of (i) sixty (60) months or (ii) the total
                  periods of pre-break Service.

         (e)      Special Rule for Extended Absence Employees--Notwithstanding
                  the preceding provisions of this Section 3.02, in the case of
                  an Extended Absence Employee, the period between the first and
                  second anniversaries of such Employee's absence shall, under
                  no circumstances, be treated as a period of Service.

         In order to participate hereunder, an Employee otherwise eligible to
         participate pursuant to Section 3.01 must, after having received a

                  requirements for disability as defined in the DIFCO Plan and
                  the disability occurred prior to October 1, 1997;

         (e)      In lieu of the qualified preretirement survivor annuity

         (b)      Additional Matching Contribution--

                  (1)      In General. For each Year, each Employer shall make
                           an additional contribution on behalf of each of its
                           Employees for whom a contribution was made pursuant
                           to paragraph (a) of this Section 4.01; provided,
                           however, that no such additional contribution shall
                           be made prior to the first day of the calendar

                           completes one (1) year of Service. Such contributions
                           shall equal an amount which, when added to the
                           Forfeitures which have become available for
                           application as of the end of the Year pursuant to

                           Notwithstanding the preceding provisions of this
                           paragraph (b), no portion of a Participant's salary
                           reduction shall be taken into account for purposes of
                           this computation if, prior to the end of such Year,
                           such portion (including any portion constituting a
                           deemed distribution pursuant to Section 6.06(c)
                           hereof) is withdrawn by, or otherwise distributed to,
                           the Participant prior to the Participant's attainment
                           of age fifty-nine and one-half (59-1/2), or if such
                           portion represents one or more contributions pursuant
                           to paragraph (a) of this Section 4.01 made prior to
                           the first day of the calendar quarter following the
                           date on which such Participant completes one (1) year
                           of Service.

                           For any Year, the Employers may decline to make any
                           portion of the contribution specified in this
                           paragraph (b) if the Employers determine that such
                           action is necessary to ensure that the discrimination
                           requirements of Section 401(a)(4) of the Code, as
                           amended, or the discrimination tests of Section
                           401(m) of the Code, as amended, are satisfied; or,
                           alternatively, in the case of a violation of the
                           discrimination tests of such Section 401(m), the
                           Employers may direct the Trustee to distribute
                           "excess aggregate contributions" (as defined in
                           Section 401(m)(6)(B) of such Code), to the
                           Participants by or on whose behalf such contributions
                           were made by the last day of the following year. All
                           additional matching contributions of the Employers
                           shall be paid to the Trustee and payment shall be
                           made not later

                           consolidated Federal income tax return of the
                           Employers, including any extensions which have been
                           granted for the filing of such tax return.

                  (2)      Discrimination Tests. With respect to Matching
                           Employer Contributions, the discrimination tests of
                           Code Section 401(m) are satisfied in the following
                           manner:

                           (a)      For the Plan Year Ending March 31, 1998: (i)

                                    Eligible Participants who are Highly

                                    Employees for the prior Year multiplied by
                                    two (2), provided that the Average
                                    Contribution Percentage for Eligible

                                    Employees does not exceed the Average
                                    Contribution Percentage for Eligible
                                    Participants who are Non-Highly Compensated
                                    Employees for the prior Year by more than
                                    two (2) percentage points.

                           In any year in which the Average Contribution
                           Percentage for Highly Compensated Employees who are
                           Eligible Participants does not satisfy the limitation
                           set forth above, the Committee shall reduce
                           allocations of Matching Employer Contributions to
                           such individuals in the manner provided in this
                           paragraph. First, the Committee shall calculate the
                           amount of "excess deferrals" and "excess
                           contributions," if any, under Section 4.03(d) and
                           shall make any required distributions thereunder.

                           Committee then determines that the Plan continues to
                           fail the Average Contribution Percentage Test for the
                           Year, it shall reduce "excess aggregate
                           contributions," as adjusted for allocable income,
                           during the next Plan Year. For purposes of this
                           paragraph, "excess aggregate contributions" are the
                           amount of aggregate Matching Employer Contributions
                           allocated on behalf of the Highly Compensated
                           Employees which causes the Plan to fail the Average
                           Contribution Percentage Test. The Committee shall
                           reduce the "excess aggregate contributions" to the
                           Highly Compensated Employees in accordance with the
                           following steps:

                           (A)      The Committee shall calculate total "excess
                                    aggregate contributions" for the Highly
                                    Compensated Employees.

                           (B)      The Committee shall calculate the total
                                    dollar amount by which the "excess aggregate
                                    contributions" for the Highly Compensated
                                    Employees must be reduced in order to
                                    satisfy the Average Contribution Percentage
                                    Test.

                           (C)      The Committee shall calculate the total
                                    dollar amount of Matching Employer
                                    Contributions for each Highly Compensated
                                    Employee.

                           (D)      The Committee shall reduce the Matching
                                    Employer Contributions of the Highly
                                    Compensated Employee(s) with the highest
                                    dollar amount of Matching Employer
                                    Contributions by reducing such contributions
                                    in such Highly Compensated Employee(s)
                                    Account in an amount necessary to cause the
                                    dollar amount of such Highly Compensated
                                    Employee(s)' Matching Employer Contributions
                                    to equal the sum of the Matching Employer
                                    Contributions of the Highly Compensated
                                    Employee(s) with the next highest dollar
                                    amount of such contributions.

                           (E)      If the total dollar amount reduced pursuant
                                    to Step (D) above is less than the total
                                    dollar amount of "excess aggregate
                                    contributions," Step (D) shall be applied to
                                    the Highly Compensated Employee(s) with the
                                    next highest dollar amount of Matching
                                    Employer Contributions until the total
                                    amount of reduced Matching Employer
                                    Contributions equals the total dollar amount
                                    of "excess aggregate contributions"
                                    calculated in Step (B).

                           (F)      When calculating the amount of reduction
                                    under Step (D), if a lesser reduction, when
                                    added to any amounts already reduced under
                                    this paragraph, would equal the total amount
                                    of reductions necessary to permit the Plan
                                    to satisfy the Average Contributions
                                    Percentage Test under this Section
                                    4.01(b)(2), the lesser amount shall be
                                    reduced instead.

                           (G)      Any Matching Employer Contributions amount
                                    reduced from a Highly Compensated Employee's
                                    Account pursuant to Step (D) above, which
                                    shall be treated as an "excess aggregate
                                    contribution" (as defined in Code Section
                                    401(m)(6)(B) and the regulations
                                    thereunder), together with the income
                                    allocable thereto, shall be distributed (or,
                                    if not vested, forfeited) to the Participant
                                    within two and one-half (2-1/2) months of
                                    the beginning of the subsequent Plan Year.

                           For purposes of this subparagraph (2), an Eligible
                           Participant's "Contribution Percentage" shall mean
                           the ratio (expressed as a percentage), of the sum of
                           the Matching Employer Contributions under the Plan on
                           behalf of the Eligible Participant for the Year to
                           such Eligible Participant's Compensation for the
                           Year. The Contribution Percentage of an Eligible
                           Participant who has no Matching Employer
                           Contributions allocated to his Employer Contribution
                           Account for the Year shall equal zero (0). "Eligible
                           Participant" shall mean any Employee who is
                           authorized under the terms of the Plan to have
                           Matching Employer Contributions allocated to his
                           Employer Contribution Account for the Year, and shall
                           include any Employee who is eligible to make Salary
                           Reduction Contributions under the terms of the Plan
                           but elects not to make such contributions for the
                           Year, who is eligible to participate under the terms
                           of the Plan but elects not to participate pursuant to
                           the provisions of Section 3.03 hereof, or who is not
                           eligible to have Matching Employer Contributions
                           allocated to his Employer Contribution Account due to
                           the limitation on Additions set forth in Section 5.03
                           hereof. The "Average Contribution Percentage" is the
                           average (expressed as a percentage) of the
                           Contribution Percentages of all Eligible
                           Participants.

                           In the event that this Plan satisfies the
                           requirements of Code Section 401(a)(4) and 410(b)
                           only if aggregated with one or more other plans, or
                           if one or more other plans satisfy the requirements
                           of Code Section 401(a)(4) and 410(b) only if
                           aggregated with this Plan, then this subparagraph (2)
                           shall be applied by determining the Contribution
                           Percentage of Eligible Participants as if all such
                           plans were a single plan. If a Highly Compensated
                           Employee participates in two (2) or more plans of the
                           Employers to which matching contributions are made
                           then all such contributions shall be aggregated for
                           purposes of this subparagraph (2).

                           The income allocable to an "excess aggregate
                           contribution" (as defined in Code Section
                           401(m)(6)(B) and regulations thereunder) shall be
                           determined by multiplying the income allocable to a
                           Participant's Employer Contribution Account for the
                           Plan Year by a fraction, the numerator of which is
                           the "excess aggregate contributions" (as defined in
                           Code Section 401(m)(6)(B) and regulations promulgated
                           thereunder) for the Participant, as determined above,
                           and the denominator of which is the balance of the
                           Participant's Employer Contribution Account on the
                           last day of the Plan

                           Year, reduced by the income allocable to such account
                           for the Plan Year and increased by the loss allocable
                           to such account for the Plan Year.

                           The Committee may, in its sole discretion, elect to
                           take contributions to a Participant's Salary
                           Reduction Contribution Account into account in
                           computing the Average Contribution Percentage, in the
                           manner and to the extent provided by Treasury
                           Department regulations promulgated under Code Section
                           401(m). However, in such a case, the Actual Deferral
                           Percentage tests under Section 4.02(e) must still be
                           computed and met separately, and in connection
                           therewith, no aggregation with Matching Employer
                           Contributions shall be permitted. Alternatively, the
                           Employer may, in its sole discretion, elect to make
                           qualified nonelective contributions, subject to the
                           vesting and distribution requirements under Sections
                           6.03 and 6.04 hereof, and in the manner and to the
                           extent provided by Treasury Department regulations
                           under Code Section 401(m), that would, in combination
                           with Matching Employer Contributions under the Plan,
                           satisfy the limitation set forth above. In any event,
                           said correction of the discrimination tests described
                           herein shall be made within twelve (12) months of the
                           end of the Year.

                           In order to prevent the multiple use of the
                           alternative limitations described in clause (ii) of
                           the first paragraph of this subparagraph (2) and in
                           Section 4.02(e)(ii) hereof, the limitation on the
                           multiple use of alternative limitations described in
                           Treasury Department regulations under Code Section
                           401(m) is specifically incorporated herein by
                           reference and shall apply to reduce the Salary
                           Reduction Contributions of, or Matching Employer
                           Contributions for, those Eligible Participants who
                           are Highly Compensated Employees, so that there is no
                           multiple use of said alternative limitations. Any
                           "excess contribution" (as defined in Code Section
                           401(k)(8)(B) and regulations thereunder) resulting
                           from a reduction in Salary Reduction Contributions
                           shall be distributed in accordance with Section
                           4.02(d), and any "excess aggregate contribution" (as
                           defined in Code Section 401(m)(6)(B) and regulations
                           thereunder) resulting from a reduction in Matching
                           Employer Contributions shall be distributed in
                           accordance with this Section. In lieu of said
                           reduction, the Employer may make such additional
                           contributions as described in this Section and
                           Section 4.02(d) hereof, in the manner and to the
                           extent provided under the Treasury Department
                           regulations under Code Sections 401(k) and 401(m), so
                           as to comply with the limitation on the multiple use
                           of alternative limitations.

         (c)      Limitations--All contributions of an Employer shall be made
                  from consolidated current earnings, as computed in accordance
                  with accepted accounting practices, before deduction of
                  Federal income taxes and reserves for contingencies, if any,
                  other than reasonable reserves of a type or character allowed
                  or allowable as deductions for Federal income tax purposes,
                  and before deduction of any contributions hereunder. In no
                  event, however, shall the Employer contributions for any Year
                  exceed the amount deductible for such Year for income tax
                  purposes (on a


                                       21

<PAGE>   22

                  consolidated return basis) as a contribution to the Trust
                  under the applicable provisions of the Code. Further, no
                  Matching Employer Contributions shall be made for a Year
                  unless the Company's earnings per share for such Year are
                  sufficient to cover dividends to stockholders; provided,
                  however, that in no event will a Matching Employer
                  Contribution be made if the Company's net profits for such
                  Year are less than Thirty-Three and One-Third Cents ($.33-1/3)
                  per share.

4.02     Participant Salary Reduction

         Upon commencement of Participation hereunder and in accordance with
         such procedures as the Committee or Trustee shall prescribe, a
         Participant shall enter into a salary reduction agreement with his
         Employer. The terms of such salary reduction agreement shall provide
         that the Participant agrees to accept a reduction in salary from the
         Employer equal to any whole percentage of his Compensation per payroll
         period, with such percentage to be not more than fourteen percent (14%)
         of such Compensation.

         In the event that the total reduction on behalf of any Participant for
         any of his or her taxable years exceeds $7,000 (or such greater amount
         as permitted under Treasury Department regulations to reflect cost-of-
         living adjustments), such "excess deferrals" (as defined in Code
         Section 402(g)(2) and regulations promulgated thereunder), together
         with income allocable thereto, shall be distributed to the Participant
         on whose behalf such reduction was made not later than April 15
         following the close of the Participant's taxable year in which the
         reduction was made, in the manner and to the extent provided under
         regulations promulgated by the Secretary of Treasury; provided that
         such excess deferrals shall first be reduced by any "excess
         contributions" previously distributed for the Plan Year beginning in
         that taxable year pursuant to Section 4.02(d) hereof.

         The income allocable to an "excess deferral" (as defined in Code
         Section 402(g)(2) and regulations promulgated thereunder) shall be
         determined by multiplying the income allocable to a Participant's
         Salary Reduction Contribution Account for the Plan Year by a fraction,
         the numerator of which is the "excess deferrals" (as defined in Code
         Section 402(g)(2) and regulations promulgated thereunder) of the
         Participant, as determined above, and the denominator of which is the
         balance of the Participant's Salary Reduction Contribution Account on
         the last day of the Plan Year, reduced by the income allocable to such
         account for the Plan Year and increased by the loss allocable to such
         account for the Plan Year.

         Amounts credited to a Participant's Salary Reduction Contribution
         Account pursuant to Section 4.01(a) and this Section shall be one
         hundred percent (100%) vested and non-forfeitable at all times.

         Further, salary reduction agreements shall be governed by the
         following:

         (a)      A salary reduction agreement shall apply to each payroll
                  period during which an effective salary reduction agreement is
                  on file with the Participant's Employer.


                                       22

<PAGE>   23

         (b)      A salary reduction agreement shall be entered into by a
                  Participant upon commencement of Participation hereunder and
                  may be terminated or suspended by the Participant at any time
                  upon notice to the Committee. In addition, if a Participant
                  voluntarily terminates or suspends his salary reduction
                  agreement, he may enter into another salary reduction
                  agreement at any time upon notice to the Committee. Finally, a
                  Participant may amend his salary reduction agreement at any
                  time upon notice to the Committee.

         (c)      Terminations or suspensions of salary reduction agreements, as
                  well as new salary reduction agreements and amendments to
                  salary reduction agreements, shall be effective as of, and
                  shall not apply to any payroll period preceding, the payroll
                  period next following the date on which such termination,
                  suspension, salary reduction agreement or amendment is
                  received by the Committee.

         (d)      An Employer may amend or revoke its salary reduction agreement
                  with any Participant at any time if the Employer determines
                  that such revocation or amendment is necessary (i) to ensure
                  that a Participant's Additions for any Year will not exceed
                  the limitation of Section 5.03 hereof, (ii) to ensure that
                  Employer contributions made pursuant to Section 4.01 hereof
                  are fully deductible by the Employer for Federal income tax
                  purposes, (iii) to ensure that a Participant's Salary
                  Reduction Contributions do not exceed the limitation of
                  Section 4.02 hereof relating to "excess deferrals" (as defined
                  in Code Section 402(g)(2) and regulations promulgated
                  thereunder), or (iv) to ensure that the discrimination tests
                  of Code Section 401(k) are met for such Year.

                  In any case in which such discrimination tests are not met for
                  a Year, the Employer may, in the alternative, (i) direct the
                  Trustee to distribute "excess contributions" (as defined in
                  Code Section 401(k)(8)(B) and regulations promulgated
                  thereunder), together with the income allocable thereto, but
                  first reduced by any "excess deferrals" (as defined in Code
                  Section 402(g)(2) and regulations promulgated thereunder)
                  previously distributed pursuant to Section 4.02 hereof for the
                  taxable year ending within the Plan Year, to the Participant
                  on whose behalf such contributions were made within two and
                  one-half (2-1/2) months of the beginning of the subsequent
                  Year, or (ii) make such additional contributions, subject to
                  the vesting and distribution requirements of Sections 6.03 and
                  6.04 hereof, and in the manner and to the extent provided by
                  regulations under Code Section 401(k) promulgated by the
                  Secretary of Treasury, to the Salary Reduction Contribution
                  Accounts of Participants who are Non-Highly Compensated
                  Employees as to cause such tests to be satisfied. The Plan
                  shall forfeit Matching Employer Contributions attributable to
                  "excess contributions" (as defined in Code Section
                  401(k)(8)(B)) distributed under the foregoing clause (i) and
                  such amounts treated as Forfeitures shall be applied as
                  Forfeitures in accordance with Section 4.03 of the Plan. In
                  any event, said correction of the discrimination tests
                  described herein shall be made within twelve (12) months of
                  the end of the Year. In addition, an Employer may amend or
                  revoke its salary reduction agreement with any Participant at
                  any time if the Employer determines that such revocation or
                  amendment is necessary to ensure that the discrimination tests
                  of Code Section 401(m) are met for such Year.

                  The income allocable to an "excess contribution" (as defined
                  in Code Section 401(k)(8)(B) and regulations promulgated
                  thereunder) shall be determined by multiplying the income
                  allocable to a Participant's Salary Reduction Contribution
                  Account for the Plan Year by a fraction, the numerator of
                  which is the "excess contributions" (as defined in Code
                  Section 401(k)(8)(B) and regulations promulgated thereunder)
                  of the Participant, as determined under Section 4.02(e), and
                  the denominator of which is the balance of the Participant's
                  Salary Reduction Contribution Account on the last day of the
                  Plan Year, reduced by the income allocable to such account for
                  the Plan Year and increased by the loss allocable to such
                  account for the Plan Year.

         (e)      The discrimination tests of Code Section 401(k) are satisfied
                  in the following manner:

                  (1)      For the Plan Year Ending March 31, 1998: the Actual
                           Deferral Percentage for Eligible Participants who are
                           Highly Compensated Employees for the Year shall bear
                           a relationship to the Actual Deferral Percentage for
                           Eligible Participants who are Non-Highly Compensated
                           Employees for the current Year whereby (i) the Actual
                           Deferral Percentage for the group of Eligible
                           Participants who are Highly Compensated Employees for
                           the Year is not more than the Actual Deferral
                           Percentage for Eligible Participants who are
                           Non-Highly Compensated Employees for the current Year
                           multiplied by 1.25; or (ii) the excess of the Actual
                           Deferral Percentage for the group of Eligible
                           Participants who are Highly Compensated Employees for
                           the Year over that of all Eligible Participants who
                           are Non-Highly Compensated Employees for the current
                           Year shall not be more than two (2) percentage
                           points, and the Actual Deferral Percentage for the
                           group of Eligible Participants who are Highly
                           Compensated Employees for the current Year is not
                           more than the Actual Deferral Percentage of all
                           Eligible Participants who are Non-Highly Compensated
                           Employees for the current Year multiplied by two (2).

                  (2)      For Plan Years Ending After March 31, 1998: the
                           Actual Deferral Percentage for Eligible Participants
                           who are Highly Compensated Employees for the Year
                           shall bear a relationship to the Actual Deferral
                           Percentage for Eligible Participants who are
                           Non-Highly Compensated Employees for the prior Year
                           whereby (i) the Actual Deferral Percentage for the
                           group of Eligible Participants who are Highly
                           Compensated Employees for the Year is not more than
                           the Actual Deferral Percentage for Eligible
                           Participants who are Non-Highly Compensated Employees
                           for the prior Year multiplied by 1.25; or (ii) the
                           excess of the Actual Deferral Percentage for the
                           group of Eligible Participants who are Highly
                           Compensated Employees for the Year over that of all
                           Eligible Participants who are Non-Highly Compensated
                           Employees for the prior Year shall not be more than
                           two (2) percentage points, and the Actual Deferral
                           Percentage for the group of Eligible Participants who
                           are Highly Compensated Employees for the

                           prior Year is not more than the Actual Deferral
                           Percentage of all Eligible Participants who are
                           Non-Highly Compensated Employees for the prior Year
                           multiplied by two (2).

                  If the allocations of the Participant Salary Reduction
                  Contributions do not satisfy the tests set forth above, the
                  Committee shall adjust the accounts of the Highly Compensated
                  Employees as provided in this paragraph. The Committee shall
                  distribute excess contributions, as adjusted for allocable
                  income, during the next Plan Year. However, the Employer will
                  incur an excise tax equal to 10% of the amount of excess
                  contributions for a Year if such contributions are not
                  distributed to the appropriate Highly Compensated Employees
                  during the first 2-1/2 months of the next Plan Year. For
                  purposes of this paragraph, "excess contributions" are the
                  amount of aggregate Salary Reduction Contributions which cause
                  the Plan to fail the Actual Deferral Percentage Test. The
                  Committee shall make distributions to each Highly Compensated
                  Employee of his or her respective share of excess
                  contributions pursuant to the following steps:

                  (A)      The Committee shall calculate total excess
                           contributions for the Highly Compensated Employees.

                  (B)      The Committee shall calculate the total dollar amount
                           by which the excess contributions for the Highly
                           Compensated Employees must be reduced in order to
                           satisfy the Actual Deferral Percentage Test.

                  (C)      The Committee shall calculate the total dollar amount
                           of the Salary Reduction Contributions for each Highly
                           Compensated Employee.

                  (D)      The Committee shall reduce the Salary Reduction
                           Contributions of the Highly Compensated Employee(s)
                           with the highest dollar amount of Salary Reduction
                           Contributions by refunding such contributions to such
                           Highly Compensated Employee(s) in an amount
                           sufficient to cause the dollar amount of such Highly
                           Compensated Employee(s)' Salary Reduction
                           Contributions to equal the dollar amount of the
                           Salary Reduction Contributions of the Highly
                           Compensated Employee(s) with the next highest dollar
                           amount of Salary Reduction Contributions.

                  (E)      If the total dollar amount distributed pursuant to
                           Step (D) above is less than the total dollar amount
                           of excess contributions, Step (D) shall be applied to
                           the Highly Compensated Employee(s) with the next
                           highest dollar amount of Salary Reduction
                           Contributions until the total amount of distributed
                           Salary Reduction Contributions equals the total
                           dollar amount of excess contributions calculated in
                           Step (B).

                  (F)      When calculating the amount of a distribution under
                           Step (D), if a lesser reduction, when added to any
                           amounts already distributed under this paragraph,
                           would equal the total amount of distributions
                           necessary to permit the Plan to satisfy the Actual
                           Deferral Percentage Test under this Section 4.03(e),
                           the lesser amount shall be distributed from the Plan.

                  For purposes of this paragraph (e), the "Actual Deferral
                  Percentage" for a specified group of Eligible Participants for
                  a Year shall be the average of the ratios (expressed as a
                  percentage and calculated separately for each Eligible
                  Participant in such group) of (i) the amount of each such
                  Eligible Participant's Salary Reduction Contributions actually
                  paid over to the Trust on behalf of the Participant for such
                  Year, to (ii) such Participant's Compensation for the Year.
                  Salary Reduction Contributions shall be taken into account for
                  the Year if such contributions (i) relate to Compensation that
                  would have been received during the Year (but for the deferral
                  election) or relate to Compensation attributable to services
                  performed during the Year that would have been received within
                  2-1/2 months after the close of the Year (but for the deferral
                  election), and (ii) are allocated to the Participant's account
                  as of a date within the Year in accordance with Treasury
                  Department regulations under Code Section 401(k). The Actual
                  Deferral Percentage of an Eligible Participant for whom no
                  Salary Reduction Contributions are paid to the Trust on his
                  behalf for the Year shall equal zero (0). "Eligible
                  Participant" shall mean any Employee who is authorized under
                  the terms of the Plan to have contributions allocated to his
                  Salary Reduction Contribution Account for all or a portion of
                  the Year, and shall include any Employee who is eligible to
                  make Salary Reduction Contributions under the terms of the
                  Plan but elects not to make such contributions for the Year,
                  who is eligible to participate under the terms of the Plan but
                  elects not to participate pursuant to the provisions of
                  Section 3.03 hereof, whose right to make Salary Reduction
                  Contributions has been suspended under Section 4.02(h)(1)
                  hereof, or who is not eligible to have Salary Reduction
                  Contributions allocated to his Salary Reduction Contribution
                  Account due to the limitations on Additions set forth in
                  Section 5.03 hereof.

                  In the event that this Plan satisfies the requirements of Code
                  Section 401(a)(4) or 410(b) only if aggregated with one or
                  more other plans, or if one or more other plans satisfy the
                  requirements of Code Section 401(a)(4) or 410(b) only if
                  aggregated with this Plan, then this paragraph (e) shall be
                  applied by determining the Contribution Percentage of Eligible
                  Participants as if all such plans were a single plan. If a
                  Highly Compensated Employee participates in two (2) or more
                  plans of the Employers to which salary reduction contributions
                  are made then all such contributions shall be aggregated for
                  purposes of this paragraph (e).

         (f)      An Employer may revoke its salary reduction agreements with
                  all Participants or amend its salary reduction agreements with
                  all Participants on a uniform basis, if it determines that it
                  will not have sufficient current profits to make the
                  contributions to the Plan required by the salary reduction
                  agreements.

         (g)      Except as provided above, a salary reduction agreement
                  applicable to any given Year, once made, may not be revoked or
                  amended by the Participant or the Employer.

         (h)      No amounts may be withdrawn by a Participant from his Salary
                  Reduction Contribution Account prior to termination of
                  employment with the Employers except to the extent of an
                  election made in accordance with the following:

                  (1)      If the Participant elects a withdrawal prior to the
                           date on which he attains age 59-1/2, such withdrawal
                           (i) may not include any earnings accrued after 1988
                           and (ii) will require the consent of the Committee.
                           Such consent shall be given only if the Participant
                           is able to demonstrate financial hardship. The
                           Committee will determine that the Participant has
                           properly demonstrated financial hardship only if the
                           Participant demonstrates that the purpose of the
                           withdrawal is to meet his immediate and heavy
                           financial needs, the amount of the withdrawal does
                           not exceed such financial needs, and the amount of
                           the withdrawal is not reasonably available from other
                           resources. The Participant will be considered as
                           having demonstrated that the purpose of the
                           withdrawal is to meet his immediate and heavy
                           financial needs only if he represents that the
                           distribution is on account of --

                           (A)      medical expenses (as described in Section
                                    213(d) of the Code) incurred (or required to
                                    be paid in advance to obtain medical care)
                                    by the Participant, his spouse or any of his
                                    dependents;

                           (B)      the purchase (excluding mortgage payments)
                                    of a principal residence for the
                                    Participant;

                           (C)      the payment of tuition and related
                                    educational fees for the next twelve (12)
                                    months of post-secondary education for the
                                    Participant, his spouse, children or
                                    dependents; or

                           (D)      foreclosure on the mortgage of, or eviction
                                    from, the Participant's principal residence.

                           Moreover, the Participant will be considered as
                           having demonstrated that the amount of the withdrawal
                           is unavailable from his other resources and in an
                           amount not in excess of that necessary to satisfy his
                           immediate and heavy financial needs only if each of
                           the following requirements is satisfied:

                           (AA)     the Participant represents that the
                                    distribution is not in excess of the amount
                                    of his immediate and heavy financial needs;
                                    and

                           (BB)     the Participant has obtained all
                                    distributions, other than hardship
                                    distributions, and all nontaxable loans
                                    currently available to him under all plans
                                    currently maintained by the Employers.

                           In the event of any withdrawal by a Participant
                           pursuant to this subparagraph (1), such Participant's
                           Salary Reduction Contributions under this Section
                           4.02 and his contributions under all other employee
                           plans maintained by the Employers shall be suspended
                           for a period of twelve (12) months following



                                       27

<PAGE>   28

                           such withdrawal, and the Participant may authorize no
                           further contributions under this Section 4.02 until
                           the first business day immediately following such
                           twelve (12) month period of suspension. Withdrawal
                           elections under this subparagraph (1) may be made at
                           any time but not more frequently than once each Plan
                           Year. All withdrawals under this subparagraph shall
                           be made in accordance with the provisions of Section
                           6.04 hereof, relating to the form of payment. To the
                           extent elected by a Participant, any hardship
                           withdrawal made pursuant to this subparagraph (1) to
                           such Participant shall be increased by an amount
                           equal to the lesser of (i) all Federal, state and
                           local income taxes and associated penalties
                           (including, if applicable, the additional income tax
                           described in Section 6.04(a) hereof) imposed with
                           respect to such hardship withdrawal or (ii) the
                           amount, if any, in such Participant's Salary
                           Reduction Contribution Account in excess of such
                           hardship withdrawal.

                  (2)      If the Participant or Former Participant elects a
                           withdrawal on or after the date on which he attains
                           age 59-1/2, such a withdrawal will not require the
                           consent of the Committee and may be made for any
                           purpose and at any time; provided that any such
                           withdrawal must be in the form of a lump sum and must
                           be made at the same time that withdrawals are made
                           pursuant to the provisions of Section 6.07(a) hereof
                           and in accordance with the requirements set forth
                           therein.

                  (3)      Any withdrawal by a Participant may not exceed the
                           balance then credited to his Salary Reduction
                           Contribution Account. Withdrawal elections shall be
                           made on written forms supplied by the Committee for
                           that purpose. If the Participant is married, his
                           spouse must specifically consent to a withdrawal
                           hereunder within a period which is ninety (90) days
                           prior to the date on which the withdrawal is made.

                  (4)      Subject to the foregoing provisions, a Former
                           Participant who is entitled to a distribution under
                           Section 6.04 but who has not yet elected to receive
                           such distribution may elect a withdrawal under this
                           Section 4.02(h) prior to the time that such
                           distribution is made if such Former Participant
                           elects to take a distribution as of the end of the
                           next calendar quarter in the form of a lump sum in
                           accordance with Section 6.04 hereof.

4.03     Disposition of Forfeitures

         If, upon a Severance from Service, a Participant is not entitled to a
         distribution of the entire balance in his Employer Contribution
         Account, then as of the date on which such Severance from Service
         occurs, his Account shall be divided into two portions, one
         representing the nonforfeitable portion, and the other representing the
         Forfeiture portion, of such Account. His Employer Contribution Account
         shall continue to receive Income allocations pursuant to Section
         5.02(a) until the nonforfeitable portion of such Account is
         distributed. The Participant shall receive a distribution of the
         nonforfeitable portion of such Account pursuant to Section 6.04.
         Notwithstanding the foregoing, prior to a Participant's sixty-fifth



                                       28

<PAGE>   29

         (65th) birthday, written consent of the Participant is required before
         commencement of the distribution of any portion of his Account if the
         present value of the nonforfeitable total interest in his Account is
         greater than $5,000.

         As of the date on which such payment occurs, the Forfeiture portion of
         such Account shall be transferred to a special interest-bearing
         "forfeiture management account". As of the end of the Year in which
         such transfer occurs, and except as otherwise provided below, such
         forfeiture management account shall be applied to reduce the Matching
         Employer Contributions to the Plan under Section 4.01(b) hereof;
         provided that, to the extent that the amount in the forfeiture
         management account available to reduce Matching Employer Contributions
         for the Year exceeds such Matching Employer Contributions and all
         restoration amounts described below, such excess shall be applied in
         payment of Trustee fees and other administrative expenses of the Plan
         and Trust.

         If the Participant returns to the employ of an Employer before
         incurring five (5) consecutive one (l)-year Breaks in Service, he shall
         have the right to repay to the Trust Fund the amount of a prior lump
         sum payment within the five (5)-year period beginning on his
         Re-employment Commencement Date. If such repayment is made, then, as of
         the end of the Year of repayment, the amount of his prior Forfeiture
         shall be restored and, together with the amount repaid, shall become
         the beginning balance in his new Employer Contribution Account. Such
         restoration shall be made first from the forfeiture management account.
         To the extent that such forfeiture management account is insufficient
         for this purpose, restoration shall be effected by the making of a
         special Employer contribution for such Year of repayment.

         Notwithstanding the preceding provisions of this Section 4.03, a
         Participant who, upon a Severance from Service, is entitled to no
         portion of his Employer Contribution Account, shall be deemed to have
         received a distribution of zero from such Account at the earliest date
         on which a distribution could be made under Section 6.04 hereof.

4.04     Rollover Contributions; Transfers

         With the approval of the Committee, any Employee who was a participant
         in another plan of deferred compensation which is qualified under
         Section 401(a) of the Code may contribute to this Plan a portion or all
         of the amount of any "qualifying rollover distribution" received by him
         from such other plan. Any amounts so contributed and related earnings
         or losses shall be held in a separate Rollover Account established for
         such Participant. Such Rollover Account shall be one hundred percent
         (100%) vested in the Participant, shall share in Income allocations in
         accordance with Section 5.02(a), but shall not share in Employer
         contribution or Forfeiture allocations. The total amount in such
         Rollover Account shall be distributed in accordance with Article VI.
         The term "qualifying rollover distribution" is herein defined as any
         amount which, pursuant to Section 402(a)(5) of the Code, may be
         transferred to this Plan and thereby not be includible in the gross
         income of the recipient for the taxable year in which paid.

         The Trustee, upon approval of the Committee, may accept a transfer from
         the trustee of another qualified plan or trust of all or any of the
         assets held by such plan or trust for some


                                       29

<PAGE>   30

         or all participants therein; provided, however, that no such transfer
         shall be accepted for any one particular individual participant in
         another qualified plan or trust. In the case of a transfer to the
         Trustee of all or any of the assets of another qualified plan or trust
         by the trustee of the transferor plan, the amounts so transferred shall
         be allocated to the individual accounts of each Participant who was
         also a participant in such other qualified plan. In no event shall a
         Participant's vested interest in such a transferred account be less
         after such transfer than it was prior to such transfer. Furthermore,
         with respect to such transferred amounts, the vesting schedule of this
         Plan shall be the same or better than the vesting schedule under the
         transferor plan, or, in the alternative, this Plan may provide that the
         entire value of such transferred amounts shall be fully vested and
         nonforfeitable in the Participant affected.

         The Trustee, upon direction from the Committee, may transfer any amount
         available for distribution to a Participant hereunder by reason of
         termination of employment to another trust forming part of a pension,
         profit sharing or stock bonus plan maintained by such Participant's new
         employer and represented by such employer in writing as meeting the
         requirements of Section 401(a) of the Code, provided that the trust to
         which such transfer is to be made permits such transfers.

4.05     Contributions by Participants

         Except as provided in Section 4.04 hereof, Participants are neither
         required nor permitted to make any contributions under this Plan.

4.06     Special Rules under USERRA

         Notwithstanding any provision of this Plan to the contrary,
         contributions, benefits and service credit with respect to qualified
         military service will be provided in accordance with Code Section
         404(u).

                      ALLOCATIONS TO PARTICIPANTS' ACCOUNTS

5.01     Individual Accounts

         The Committee shall create and maintain adequate records to disclose
         the interest in the Trust of each Participant, Former Participant, and
         Beneficiary. Such records shall be in the form of individual accounts
         and credits and charges shall be made to such accounts in the manner
         herein described. When appropriate, a Participant, Former Participant,
         and Beneficiary shall have three separate accounts--an Employer
         Contribution Account, a Salary Reduction Contribution Account, and a
         Rollover Account. The maintenance of individual accounts is only for
         accounting purposes, and a segregation of the assets of the Trust Fund
         to each account shall not be required.

5.02     Account Adjustments

         The accounts of Participants, Former Participants, and Beneficiaries
         shall be adjusted in accordance with the following:

         (a)      Income--As of each Valuation Date, the Income of the Trust
                  Fund shall be allocated in the following manner:

                  (1)      The Income (hereinafter, the "Fund Income")
                           attributable to each investment fund (hereinafter,
                           "Fund") established pursuant to Article VII hereof
                           (including, as a separate investment fund, assets, if
                           any, invested at the discretion of the Trustee) shall
                           first be determined.

                  (2)      Fund Income shall then be allocated pro rata to the
                           accounts of Participants, Former Participants, and
                           Beneficiaries who had unpaid balances in their
                           accounts invested in such Fund on such Valuation
                           Date.

         (b)      Salary Reduction Contributions--The Employer contribution for
                  a Year made on behalf of a Participant pursuant to Section
                  4.01(a) hereof shall be allocated to the Participant's Salary
                  Reduction Contribution Account as of a date no later than the
                  last day of such Year.

         (c)      Matching Employer Contributions--As of a date no later than
                  the last day of each Year, the Matching Employer Contributions
                  for the Year made pursuant to Section 4.01(b) hereof plus the
                  Forfeitures which are being applied to reduce such Matching
                  Employer Contributions for the Year, shall be allocated to the
                  Employer Contribution Accounts of Participants for whom such
                  contributions were made. The amount allocated to each such
                  Participant's Employer Contribution Account shall be the
                  amount determined in accordance with such Section 4.01(b)

5.03     Maximum Additions

         (a)      Notwithstanding anything contained herein to the contrary, the
                  total additions made to the Salary Reduction Account and
                  Employer Contribution Account of a Participant for any Year
                  shall not exceed the lesser of (1) or (2), where--

                  (1)      is the greater of $30,000 (or such greater amount as
                           permitted under Internal Revenue Service rulings to
                           reflect increases in the cost-of-living) or
                           one-fourth (1/4) of the dollar limitation in effect
                           under Section 415(b)(1)(A) of the Code; and

                  (2)      is 25% of the Participant's total compensation for
                           such Year.

                  For purposes of this Section 5.03, a Participant's "total
                  compensation" includes earned income, wages, salaries, fees
                  for professional service and other amounts received for
                  personal services actually rendered in the course of
                  employment with his Employer (including, but not limited to,
                  commissions paid to salesmen,



                                       31

                  compensation for services on the basis of a percentage of
                  profits, commissions on insurance premiums, tips, and bonuses)
                  and excluding the following: (i) Employer contributions to a
                  plan of deferred compensation to the extent contributions are
                  not included in the gross income of a Participant for the
                  taxable year in which contributed, or on behalf of a
                  Participant to a simplified employee pension plan under
                  Section 219(b)(7) of the Code, and any distributions from a
                  plan of deferred compensation whether or not includible in the
                  gross income of the Participant when distributed, provided
                  that a Participant's "total compensation" shall include his
                  Salary Reduction Contributions and contributions to a plan
                  described in Code Section 125; (ii) amounts realized from the
                  exercise of a non-qualified stock option, or when restricted
                  stock (or property) held by a Participant becomes freely
                  transferable or is no longer subject to a substantial risk of
                  forfeiture; (iii) amounts realized from the sale, exchange or
                  other disposition of stock acquired under a qualified stock
                  option; (iv) other amounts which receive special tax benefits,
                  or contributions made by the Employer (whether or not under a
                  salary reduction agreement) towards the purchase of an annuity
                  contract described in Section 403(b) of the Code (whether or
                  not the contributions are excludible from the gross income of
                  the Participant); and (v) compensation in excess of $150,000
                  (as automatically increased in accordance with Treasury
                  Department regulations to reflect cost-of-living adjustments).

         (b)      If such Additions exceed the limitations set forth in
                  paragraph (a), above, such excess shall be deemed to arise
                  solely from Matching Employer Contributions described in
                  Section 4.01(b) hereof and the amount of such contributions
                  constituting the excess shall be treated as a Forfeiture for
                  the Year. In the event that all or any portion of such excess
                  cannot be treated as a Forfeiture for such Year because of the
                  application of paragraph (a), above, the amount which cannot
                  be so treated shall be held in a suspense account until it can
                  be so treated in a subsequent Year, and no further Additions
                  shall be made to Participants' accounts until the amount in
                  such suspense account has been fully disposed of.
                  Notwithstanding any provision to the contrary herein
                  contained, if this Plan terminates during any Year in which
                  such suspense account cannot be disposed of because of the
                  application of paragraph (a), above, the amount in the
                  suspense account shall revert to the Employers.

         (c)      Notwithstanding the foregoing, the otherwise permissible
                  annual Additions for any Participant under this Plan may be
                  further reduced to the extent necessary, as determined by the
                  Committee, to prevent disqualification of the Plan under
                  Section 415 of the Code, which imposes the following
                  additional limitations on the benefits payable to Participants
                  who also may be participating in another tax-qualified
                  pension, profit-sharing, savings or stock bonus plan
                  maintained by an Employer: If an individual is a Participant
                  at any time in both a defined benefit plan and a defined
                  contribution plan maintained by the Employer, the sum of the
                  defined benefit plan fraction and the defined contribution
                  plan fraction for any Plan Year may not exceed 1.0. The
                  defined benefit plan fraction for any Plan Year is a fraction,
                  the numerator of which is the Participant's projected annual
                  benefit under the Plan (determined at the close of the Plan
                  Year) and the denominator of which is the lesser of (i) 1.25

                  multiplied by $90,000 or such greater amount permitted by
                  Internal Revenue Service regulations to reflect cost-of-living
                  adjustments, or (ii) 1.4 multiplied by one hundred percent
                  (100%) of the Participant's average monthly compensation, as
                  defined in the applicable Income Tax regulations under Section
                  415 of the Code, during the three consecutive years when the
                  total compensation paid to him was highest. The defined
                  contribution plan fraction for any Plan Year is a fraction,
                  the numerator of which is the sum of the annual Additions to
                  the Participant's accounts in such Plan Year and for all prior
                  Plan Years and the denominator of which is the sum of the
                  applicable maximum amounts of annual Additions which could
                  have been made under Section 415(c) of the Code for such Plan
                  Year and for all prior years of such Participant's employment
                  (assuming for this purpose, that said Section 415(c) had been
                  in effect during such prior years). The applicable maximum
                  amount for any Plan Year shall be equal to the lesser of (i)
                  1.25 multiplied by the dollar limitation in effect for such
                  Plan Year under Section 415(c)(1)(A) of the Code, or (ii) 1.4
                  multiplied by twenty five percent (25%) of the Participant's
                  total compensation for such Plan Year.

         (d)      For purposes of this limitation, all defined benefit plans of
                  the Employer, whether or not terminated, are to be treated as
                  one defined benefit plan and all defined contribution plans of
                  the Employer, whether or not terminated, are to be treated as
                  one defined contribution plan. The extent to which a
                  Participant's annual Additions under the Plan shall be reduced
                  as compared to the extent to which his annual benefits or
                  Additions under any other plans shall be reduced in order to
                  achieve compliance with the limitations of Section 415 of the
                  Code shall be determined by the Committee in such a manner as
                  to maximize the aggregate benefits payable to such
                  Participant. If such reduction is under this Plan, the
                  Committee shall advise the affected Participant of any
                  additional limitations on his annual benefits required by this
                  paragraph.

         (e)      The above limitations are intended to comply with the
                  provisions of Section 415 of the Code, so that the maximum
                  benefits provided by plans of the Employers shall be exactly
                  equal to the maximum amounts allowed under Section 415 of such
                  Code and regulations thereunder. If there is any discrepancy
                  between the provisions of Section 415 of such Code and the
                  provisions of this Plan, such discrepancy shall be resolved in
                  such a way as to give full effect to the provisions of such
                  Section 415.

         (f)      For purposes of this Plan, the "limitation year" shall be the
                  Plan Year.

         (g)      Notwithstanding the foregoing, the combined plan limitations
                  as defined in Code Section 415(e) and described in paragraphs
                  (c) and (d) above shall not be applied to limitation years
                  beginning after December 31, 1999.

5.04     Top-Heavy Provisions

         The following provisions shall become effective in any Year in which
         the Plan is determined to be a Top-Heavy Plan:

         (a)      Determination of Top-Heavy Status--The Plan will be considered
                  a Top-Heavy Plan for the Year if as of the last day of the
                  preceding Plan Year, (the "determination date"):

                  (1) The value of the sum of Employer Contribution Accounts and
                  Salary Reduction Contribution Accounts (but not including any
                  allocations to be made as of such last day of the Year except
                  contributions actually made on or before that date and
                  allocated pursuant to Section 5.02(b) or (c)) of Participants
                  who are Key Employees and their Beneficiaries exceeds sixty
                  percent (60%) of the value of the sum of Employer Contribution
                  Accounts and Salary Reduction Contribution Accounts (but not
                  including any allocations to be made as of such last day of
                  the Year, except contributions actually made on or before that
                  date and allocated pursuant to Section 5.02(b) or (c)) of all
                  Participants and their Beneficiaries (the "60% Test") or (2)
                  the Plan is part of a required aggregation group (within the
                  meaning of Code Section 416(g)(2)) and the required
                  aggregation group is top-heavy. However, and notwithstanding
                  the results of the "60% Test", the Plan shall not be
                  considered a Top-Heavy Plan for any Year in which the Plan is
                  a part of a required or permissive aggregation group (within
                  the meaning of Section 416(g)(2)) which is not top-heavy. For
                  purposes of the "60% Test" for any Plan Year, (i) the value of
                  the Employer and Salary Reduction Contribution Accounts of
                  individuals who are former Key Employees shall not be taken
                  into account, (ii) the value of the Employer and Salary
                  Reduction Contribution Accounts of individuals who have not
                  rendered services to the Employers for the five (5)-year
                  period ending on the determination date shall not be taken
                  into account, and (iii) any contribution of eligible rollover
                  contributions, or any plan-to-plan transfer described in
                  Section 4.05 hereof, shall not be treated as part of the
                  Participant's Employer or Salary Reduction Contribution
                  Account.

                  (2)      Aggregation shall be determined as follows:

                           (A)      Aggregation Group-

                                    (i)     Required Aggregation-The term
                                            "aggregation group" means-

                                            (I)  each  plan of the Employer in
                                                 which a Key Employee is a
                                                 participant, and

                                            (II) each other plan of the Employer
                                                 that enables any plan described
                                                 in subclause (I) to meet the
                                                 requirements of Section
                                                 401(a)(4) or 410.

                                    (ii)    Permissive Aggregation-The Employer
                                            may treat any plan not required to
                                            be included in an aggregation group
                                            under clause (i) as being part of
                                            such group if such group would
                                            continue to meet the requirements of
                                            Code Sections 401(a)(4) and 410 with
                                            such plan being taken into account.

                           (B)      Top-Heavy Group-The term "top-heavy group"
                                    means any aggregation group if-

                                    (i)     the sum (as of the determination
                                            date) of-

                                                     (I) the present value of
                                            the cumulative accrued benefits for
                                            Key Employees under all defined
                                            benefit plans included in such
                                            group, and

                                                     (II) the aggregate of the
                                            accounts of Key Employees under all
                                            defined contribution plans included
                                            in such group,

                                    (ii)    exceeds sixty percent (60%) of a
                                            similar sum determined for all
                                            Employees.

         (b)      Minimum Allocations--Notwithstanding the provisions of
                  Sections 5.02(b) and (c), for any Year during which the Plan
                  is deemed a Top-Heavy Plan, the amount of Employer
                  contribution for the Year to be allocated to the Employer
                  Contribution Account of each Participant who is not a Key
                  Employee and who is employed by the Employers on the last day
                  of the Year shall not be less than the lesser of (i) three
                  percent (3%) of the Participant's total compensation for the
                  Year or (ii) the percentage obtained by dividing the amount
                  allocated to the Salary Reduction Contribution Account and
                  Employer Contribution Account of the most highly compensated
                  Key Employee for the Year by so much of the total compensation
                  of such Key Employee for the Year as does not exceed $150,000
                  (as automatically increased in accordance with Treasury
                  Department regulations); provided,, however, that an amount
                  allocated to the Salary Reduction Contribution Account of a
                  Participant who is not a Key Employee shall not be considered
                  in determining the minimum allocation for such Participant
                  hereunder; provided, further, that the requirements of this
                  paragraph (b) shall not apply to the extent that the minimum
                  allocations set forth herein are made under another defined
                  contribution plan maintained by the Employer.

         (c)      Impact on Maximum Benefits--For any Plan Year in which the
                  Plan is a Top-Heavy Plan, Section 5.03 shall be read by
                  substituting the number 1.00 for the number 1.25 wherever it
                  appears therein; provided, however, that where the Plan is not
                  a "Super" Top-Heavy Plan (as defined in Code Section
                  416(h)(2)(B)), no such substitution shall occur if, for such
                  Plan Year, the minimum allocations determined pursuant to
                  paragraph (b) of this Section are determined by reference to
                  four percent (4%), in lieu of three percent (3%), of total
                  compensation.

         (d)      "Total Compensation" Defined--The term "total compensation" as
                  used in this Section 5.04 shall have the same meaning as that
                  set forth in Section 5.03(a) hereof.

                                    BENEFITS

6.01     Retirement or Disability

         (a)      In General--If a Participant's employment with his Employer is
                  terminated at or after his normal retirement date, or if his
                  employment is terminated prior to his normal retirement date
                  because of Disability, he shall be entitled to receive the
                  entire amount then in each of his accounts in accordance with
                  Section 6.04. The "entire amount" in a Participant's accounts
                  at termination of employment shall include any Employer
                  contribution to be made pursuant to Section 4.01 for the Year
                  of termination of employment but not yet allocated. If a
                  Participant remains in employment after his normal retirement
                  date, he shall continue to be treated as an active Participant
                  hereunder. For purposes of this Plan, the term "normal
                  retirement date" means, with respect to a Participant, the
                  first day of the month coincident with, or immediately
                  following, his attainment of age sixty-five (65).

         (b)      Required Beginning Date--Except to the extent that Section
                  1121(d)(4) of the Tax Reform Act of 1986 provides otherwise, a
                  Participant must commence receipt of his benefits not later
                  than April 1 of the calendar year following the calendar year
                  in which he attains age seventy and one-half (70-1/2);
                  provided, however, that no such commencement shall be required
                  in the case of a Participant who attains age seventy and
                  one-half (70-1/2) after calendar year 1996 (other than a
                  Participant who is a five-percent (5%) owner described in
                  Section 401(a)(9)(C)(ii)(I) of the Code). Notwithstanding the
                  preceding sentence (i) a Participant who has attained age
                  seventy and one-half (70-1/2) prior to calendar year 1997
                  shall have the right to elect the commencement of his benefit
                  payments on April 1 of the calendar year following the
                  calendar year in which he attains such age, and (ii) a
                  Participant currently receiving benefit payments solely
                  because of the attainment of such age prior to calendar year
                  1997 shall have the right to elect the suspension of such
                  benefit payments until the date specified in Section 6.04
                  hereof (determined without regard to this Section 6.01). Any
                  such election shall be made at such time and in such manner as
                  the Committee shall determine in a nondiscriminatory manner.

6.02     Death

         In the event that the termination of employment of a Participant is
         caused by his death, the entire amount then in each of his accounts
         shall be paid to his Beneficiary in accordance with Section 6.04 after
         receipt by the Committee of acceptable proof of death. The "entire
         amount" in a Participant's accounts at termination of employment shall
         include any Employer contributions to be made pursuant to Section 4.01
         for the Year of termination of employment but not yet allocated.

6.03     Termination for Other Reasons

         If a Participant's employment with his Employer is terminated before
         his normal retirement date for any reason other than Disability or
         death, the Participant shall be entitled to the sum of:

         Payment of benefits due under this Section shall be made in accordance
         with Section 6.04. Notwithstanding any provision to the contrary herein
         contained, a Participant shall be fully vested in his Employer
         Contribution Account balance upon his attainment of age sixty-five
         (65). In the event that the Plan is amended to change the vesting
         schedule set forth above, a Participant with at least three (3) years
         of Service shall have the right to elect that his vested percentage be
         determined pursuant to the vesting schedule in effect prior to the
         amendment.

6.04     Payments of Benefits

         The following provisions shall apply with respect to the method and
         timing of benefit payments hereunder:

         (a)      In General--Payment of a Participant's (or Former
                  Participant's) benefits upon entitlement under Sections
                  6.01-6.03 hereof shall commence as soon as administratively
                  feasible following the receipt by the Trustee of the last
                  contribution made on behalf of such Participant or Former
                  Participant; provided that payment in no event shall commence
                  earlier than the end of the month immediately following the
                  month in which such entitlement occurs; provided further that
                  payment prior to the date set forth in the immediately
                  following sentence shall be made only upon completion by the
                  recipient of a distribution request in such form as may be
                  specified from time to time by the Committee; provided further
                  that, in the case of a



                                       37

<PAGE>   38

                  Participant or Former Participant whose vested account balance
                  exceeds $5,000, such account balance shall not be distributed
                  without the consent of the Participant or Former Participant,
                  unless such Participant or Former Participant has attained age
                  sixty-five (65). However, and notwithstanding anything to the
                  contrary herein contained, payment of his benefits must
                  commence no later than the earlier of (i) the required
                  beginning date, if any, applicable to the Participant or
                  Former Participant pursuant to Section 6.01(b) hereof, or (ii)
                  unless a Participant or Former Participant elects a later date
                  (which can be no later than the date, if any, specified in
                  clause (i) of this sentence), the sixtieth (60th) day after
                  the latest of the close of the Year in which the Participant
                  attains age sixty-five (65) or incurs a Severance from
                  Service; provided that, in the case of (ii) of this sentence,
                  if the amount of a payment cannot be ascertained by such
                  sixtieth (60th) day, a payment retroactive to such date may be
                  made no later than sixty (60) days after the earliest date on
                  which the amount of such payment can be ascertained. If a
                  Participant or Former Participant elects that a benefit
                  payment be made to him before his attainment of age fifty-nine
                  and one-half (59-1/2), the Participant or Former Participant
                  shall be advised by the Committee that an additional income
                  tax may be imposed equal to ten percent (10%) of the portion
                  of the amount so received which is included in his gross
                  income for the taxable year of receipt unless, among others,
                  (i) such distribution is made on account of death or
                  Disability, (ii) such distribution is part of a scheduled
                  series of substantially equal periodic payments for the life
                  of the Participant or Former Participant (or the joint life
                  expectancies of the Participant or Former Participant and his
                  Beneficiary, (iii) such distribution is used to pay medical
                  expenses to the extent deductible under Section 213 of the
                  Code (determined without regard to whether the Participant or
                  Former Participant itemizes deductions), (iv) such
                  distribution is made to an alternate payee pursuant to a
                  "qualified domestic relations order" described in Section 9.03
                  hereof, or (v) such distribution is made to a Participant by
                  reason of "early retirement." For purposes of the preceding
                  sentence, a Participant who terminates employment on or after
                  his attainment of age 55 for reasons other than death,
                  Disability or normal retirement shall be treated as having
                  separated from service by reason of early retirement and shall
                  be entitled to that portion of his benefit determined pursuant
                  to Section 6.03 hereof, to be payable, subject to the
                  foregoing provisions of this Section 6.04, as of the date of
                  his early retirement. The Committee shall direct the Trustee
                  to distribute the Participant's (or Former Participant's)
                  benefits in any one of the following two methods, as elected
                  by the recipient:

                  (1)      In a lump sum; or

                  (2)      In periodic payments of substantially equal amounts
                           for a specified number of years not in excess of ten
                           (10) (or, if less, the life expectancy of the
                           Participant or Former Participant or the joint life
                           expectancy of the Participant or Former Participant
                           and his Beneficiary designated in accordance with
                           Section 6.05), in which event the unpaid balance
                           shall continue to receive an Income allocation in
                           accordance with Section 5.02(a). Such periodic
                           payments shall be made not less frequently than
                           annually. If periodic payments are made to a
                           Participant or Former Participant prior to



                                       38

                           his death and if the Participant or Former
                           Participant dies before receiving all payments to
                           which he was entitled, the remaining payments shall
                           be made at least as rapidly to his designated
                           Beneficiary. If the Participant or Former Participant
                           dies before payment of his benefits has commenced,
                           his benefits must be distributed in full within five
                           (5) years from the date of his death, unless such
                           distribution is made to the Participant's (or Former
                           Participant's) designated Beneficiary, in which case,
                           if distribution begins no later than one (1) year
                           after the date of the Participant's (or Former
                           Participant's) death, distribution may be made over
                           ten (10) years (or, if less, the life expectancy of
                           the designated Beneficiary).

                           Notwithstanding any provision of this Section 6.04 to
                           the contrary, a Participant, Former Participant, or
                           Beneficiary who has previously elected to receive
                           benefits in periodic payments of substantially equal
                           amounts for a specified number of years may, at any
                           time, elect to have the remaining balance of such
                           benefits paid in a lump sum as soon as practicable
                           following such election. The amount which a
                           Participant, Former Participant, or Beneficiary is
                           entitled to receive at any time and from time to time
                           may be paid in cash or in securities, or in any
                           combination thereof, provided no discrimination in
                           value results therefrom. In all cases, distributions
                           from the Plan will be made in accordance with the
                           requirements of Section 401(a)(9) of the Code and the
                           Treasury Department regulations thereunder, including
                           the minimum distribution incidental benefit
                           requirements.

         (b)      Special Rules Applicable to Married
                  Participants--Notwithstanding the preceding provisions of this
                  Section 6.04, the following special rules shall apply with
                  respect to payments made to or on behalf of a married
                  Participant or a married Former Participant who received a
                  transfer to this Plan of assets (other than a transfer made
                  pursuant to a qualifying rollover distribution described in
                  Section 4.04 hereof), from a plan described in Section
                  401(a)(11)(b)(i) and (ii) of the Code:

                  (1)      Pre-Retirement Survivor Annuity. Any death benefits
                           payable pursuant to Section 6.02 hereof, shall be
                           paid to the Participant's (or Former Participant's)
                           surviving spouse in the form of a life annuity;
                           provided, however, that, at any time prior to the
                           Participant's (or Former Participant's) death, the
                           Participant or Former Participant and his spouse may,
                           by written election acknowledging the effect of such
                           election, direct that such death benefits be payable
                           to one or more other Beneficiaries and in a form
                           provided under paragraph (a) above.

                  (2)      Qualified Joint and Survivor Annuity. Any benefits
                           payable under Section 6.01 or 6.03 hereof, shall be
                           paid in the form of a joint and survivor annuity
                           under which a monthly amount is payable to the
                           Participant or Former Participant for his life, and,
                           upon his death, no less than fifty percent (50%), nor
                           more than one hundred percent (100%), of such monthly
                           amount is payable to his spouse, if surviving, for
                           the remainder of the spouse's life; provided,
                           however, that within a period beginning ninety (90)
                           days prior to



                                       39

<PAGE>   40

                           the date on which benefits commence, the Participant
                           or Former Participant and his spouse may, by a
                           written election acknowledging the effect of such
                           election, direct that the Participant's (or Former
                           Participant's) benefits be paid in a form provided
                           under paragraph (a) above.

         (c)      Distribution of Small Amounts--Notwithstanding the preceding
                  provisions of this Section 6.04, a Participant's (or Former
                  Participant's) benefits hereunder shall in all events be paid
                  in a lump sum if the total of such benefits is $5,000 or less;
                  provided, however, that unless otherwise requested by the
                  distributee, no payment shall be made prior to the end of the
                  year in which entitlement to such payment occurs.

         (d)      Direct Rollovers--Notwithstanding any provision of the Plan to
                  the contrary, the recipient of all or any portion of a
                  Participant's (or Former Participant's) benefits, other than a
                  Beneficiary who is not a surviving spouse, may elect, in the
                  manner prescribed by the Committee, to have any portion of an
                  eligible rollover distribution paid directly to an individual
                  retirement account described in Section 408(a) of the Code, an
                  individual retirement annuity described in Section 408(b) of
                  the Code, an annuity plan described in Section 403(a) of the
                  Code, or a qualified trust described in Section 401(a) of the
                  Code, that will accept the eligible rollover distribution, as
                  specified by the recipient; provided, however, that a
                  recipient who is a surviving spouse may elect a direct
                  rollover to an individual retirement account or individual
                  retirement annuity only. For purposes of this Section 6.04(d),
                  an "eligible rollover distribution" shall mean any
                  distribution of all or any portion of the balance to the
                  credit of the recipient, except (i) a distribution that is one
                  of a series of substantially equal periodic payments (not less
                  frequently than annually) made for the life (or life
                  expectancy) of the recipient or the joint lives (or joint life
                  expectancies) of the recipient and the recipient's designated
                  Beneficiary, or for a specified period of ten (10) years or
                  more; (ii) a distribution to the extent such distribution is
                  required under Section 401(a)(9) of the Code; or (iii) the
                  portion of any distribution that is not includible in gross
                  income.

6.05     Designation of Beneficiary

         Each Participant or Former Participant from time to time may designate
         any person or persons (who may be designated contingently or
         successively and who may be an entity other than a natural person) as
         his Beneficiary or Beneficiaries to whom his Plan benefits are paid if
         he dies before receipt of all such benefits. Each Beneficiary
         designation shall be on a form prescribed by the Committee and will be
         effective only when filed with the Committee during the Participant's
         (or Former Participant's) lifetime. Each Beneficiary designation filed
         with the Committee will cancel all Beneficiary designations previously
         filed with the Committee. Except as otherwise provided below, the
         revocation of a Beneficiary designation, no matter how effected, shall
         not require the consent of any designated Beneficiary.

         If any Participant or Former Participant fails to designate a
         Beneficiary in the manner provided herein, or if the Beneficiary
         designated by a deceased Participant or Former Participant dies before
         him or before complete distribution of the Participant's (or Former



                                       40

<PAGE>   41

         Participant's) benefits, the Committee shall direct the Trustee to
         distribute such Participant's (or Former Participant's) benefits (or
         the balance thereof) to his surviving spouse or, if he has no surviving
         spouse, then, in the Committee's discretion, to either:

         (a)      any one or more of the next of kin of such Participant or
                  Former Participant, and in such proportions as the Committee
                  determines; or

         (b)      the estate of the last to die of such Participant or Former
                  Participant and his Beneficiary or Beneficiaries.

         Notwithstanding any provision to the contrary herein contained, the
         designation, by a married Participant or a married Former Participant,
         of a Beneficiary other than his spouse shall require the written
         consent of such spouse. The consent must name the designated
         Beneficiary or Beneficiaries who are to be the recipients of the
         Participant's (or Former Participant's) benefits. The spouse's consent
         must acknowledge the effect of the election and be witnessed by a
         notary public or Plan representative.

6.06     Loans to Participants

         The Committee is authorized to establish a program of Participant loans
         from the Trust Fund. A loan shall be made to a Participant upon his
         representation that he is subject to a financial emergency, and the
         Committee shall be entitled to rely conclusively on any such
         representation.

         In addition to such rules and regulations as the Committee may adopt,
         all loans shall comply with the following rules and conditions:

         (a)      An application for a loan by a Participant shall be made in
                  writing to the Committee, whose action thereon shall be final.
                  If the Participant is married, his spouse must specifically
                  consent to the application within a period which is ninety
                  (90) days prior to the date on which the loan is made.

         (b)      The period of repayment for any loan shall be arrived at by
                  agreement between the Committee and the borrower, but such
                  period in no event shall exceed five (5) years; provided,
                  however, that such period may exceed five (5) years where the
                  proceeds of the loan are to be used to acquire, construct,
                  reconstruct or substantially rehabilitate a dwelling which is
                  to be used within a reasonable time as the principal residence
                  of the Participant or a dependent of the Participant. The loan
                  (i) must be in level payments, made not less frequently than
                  quarterly, over the term of the loan, with privilege of
                  prepayment, in whole (but not in part), at any time, and (ii)
                  prior to termination of the borrowing Participant's
                  employment, shall be repaid by payroll deduction. Within the
                  limitations of the immediately preceding sentence, the precise
                  manner and frequency of payments shall be determined by the
                  Committee at the time that the loan is made.

         (c)      Each loan made to a Participant shall be secured by (i) an
                  assignment and pledge of not more than 50%, as determined
                  immediately after the origination of the loan as of


                                       41

<PAGE>   42

                  the current Valuation Date, of his right, title and interest
                  in and to his Salary Reduction Contribution Account plus the
                  vested portion of his Employer Contribution Account, and (ii)
                  his promissory note for the amount of the loan, including
                  interest payable to the order of the Trustee. A "default"
                  shall occur upon the failure by a Participant to make payment
                  under the loan by the end of the calendar quarter following
                  the calendar quarter in which the due date of such payment
                  occurred; provided that in the case of a Participant who is on
                  an Authorized Leave of Absence for medical reasons, no default
                  shall occur until the end of a twelve (12)-month period
                  beginning on such due date. Upon default, the entire remaining
                  principal balance of the loan shall be treated as a deemed
                  distribution to the Participant from the Plan, and the amount
                  of such deemed distribution shall be reported to the Internal
                  Revenue Service on Form W2-P or Form 1099-R, as appropriate.

         (d)      Each loan shall bear a rate of interest equal to the "prime
                  lending rate" of the Trustee bank at the time such loan is
                  made.

         (e)      No loan shall be made in an amount less than $1,000. In
                  addition with respect to a Participant, no more than two loans
                  may be outstanding at any time.

         (f)      No amount shall be loaned to a Participant which would cause
                  his outstanding loan balance under the Plan to exceed the
                  lesser of (1) or (2), where-

                  (1)      is $50,000 reduced by the excess of the highest
                           outstanding balance of loans to such Participant over
                           the twelve (12) month period ending on the day before
                           the loan is made over the outstanding balance of
                           loans to such Participant on the date the loan is
                           made, and

                  (2)      is one-half (1/2) of the value of his Salary
                           Reduction Contribution Account plus the vested
                           portion of his Employer Contribution Account as of
                           the current Valuation Date.

         (g)      No distribution (other than a hardship withdrawal described in
                  Section 4.02(h)(1) hereof) shall be made to any Participant or
                  Former Participant or to a Beneficiary of any such Participant
                  unless and until all unpaid loans of such Participant have
                  been liquidated. Foreclosure against a Participant's Employer
                  Contribution Account and Salary Reduction Contribution Account
                  shall occur immediately upon default and shall result in the
                  reduction of such account balances to the extent of unpaid
                  principal; provided that there shall be no foreclosure against
                  a Participant's account balances until the occurrence
                  hereunder of an event permitting distribution of such account
                  balances.

         (h)      Loans shall be made available to Former Participants who are
                  parties-in-interest only as required by ERISA and Department
                  of Labor guidelines.

         (i)      Any loan made prior to April 1, 1999 under the Plan shall
                  continue to be governed by the provisions of the Plan as in
                  effect prior to such date and applicable to such loan.


                                       42

         (j)      The Committee may from time to time promulgate such additional
                  procedures as it deems necessary, in its sole discretion, for
                  the governance of Plan loans; provided that such procedures
                  shall be consistent with the foregoing provisions of this
                  Section 6.06 and shall be applied in a uniform and
                  nondiscriminatory manner.

         (k)      Loan repayments will be suspended under this Plan, as
                  permitted under Code Section 414(u)(4), on behalf of those
                  Participants who are on an Authorized Leave of Absence because
                  of "qualified military service," as defined in Code Section
                  414(u).

6.07     Other Withdrawals

         (a)      Paid to a Participant--A Participant or Former Participant may
                  elect to receive a lump-sum distribution of the vested amount
                  in his Employer Contribution Account at any time after such
                  Participant or Former Participant attains age fifty-nine and
                  one-half (59-1/2). A Former Participant who is entitled to a
                  distribution under Section 6.04 but who has not yet elected to
                  receive such distribution may elect a withdrawal under this
                  Section 6.07 prior to the time that such distribution is made
                  if such Former Participant elects to take a distribution in
                  the form of a lump sum at the time specified in, and in
                  accordance with, Section 6.04 hereof. In addition, a
                  Participant or Former Participant may elect to receive a
                  lump-sum distribution of his Rollover Account at any time upon
                  a showing of financial hardship (as described in Section 4.02
                  hereof). Withdrawal elections under this Section 6.07 shall be
                  made on written forms supplied by the Committee for that
                  purpose. If the Participant or Former Participant is married,
                  his spouse must specifically consent to a withdrawal hereunder
                  within a period which is ninety (90) days prior to the date on
                  which the withdrawal is made.

         (b)      Paid to an Alternate Payee--Any amounts payable, pursuant to
                  Section 414(p) of the Code, to an "alternate payee" (as
                  defined in such Section) shall be distributed to such payee in
                  a lump sum as soon as reasonably possible after such payee's
                  right to such distribution is established by a "qualified
                  domestic relations order" (as defined in such Section);
                  provided that if the amount distributable to such payee
                  exceeds $5,000, such payee must consent to any such
                  distribution made prior to his or her attainment of age
                  sixty-five (65). An alternate payee shall be entitled to
                  receive a distribution pursuant to this paragraph (b) even
                  though the associated Participant may be ineligible to receive
                  a distribution of any portion or all of his vested account
                  balances hereunder and notwithstanding that the related
                  qualified domestic relations order may mandate distribution to
                  such alternate payee at a later date. This paragraph (b) is
                  intended to govern the timing of a distribution to an
                  alternate payee and shall not be construed to increase the
                  amount of such distribution.

                                   TRUST FUND

7.01     General

         All contributions under this Plan shall be paid to the Trustee and
         deposited in the Trust Fund. All assets of the Trust Fund, including
         investment income, shall be retained for the exclusive benefit of
         Participants, Former Participants, and Beneficiaries and shall be used
         to pay benefits to such persons or to pay administrative expenses of
         the Plan and Trust Fund to the extent not paid by the Employers and,
         except as provided in Section 5.03(b) and below, shall not revert to or
         inure to the benefit of the Employers.

         Notwithstanding anything herein to the contrary and pursuant to Section
         403(c)(2) of ERISA, upon an Employer's request, a contribution which
         was made by reason of a mistake of fact, or conditioned upon the
         initial qualification of the Plan or upon the deductibility of the
         contribution under Section 404 of the Code, shall be returned to the
         Employer within one year after the payment of the contribution, the
         denial of the qualification, or the disallowance of the deduction (to
         the extent disallowed), whichever is applicable. It is hereby
         acknowledged that (i) all contributions hereunder are expressly
         conditioned on the deductibility of such contributions and (ii) the
         continued existence of the Plan is conditioned on its
         tax-qualification.

         The Trustee shall generally have authority for the management and
         investment of assets held in the Trust, to the extent provided in the
         Trust; provided that a Participant, Former Participant, or Beneficiary
         shall have the right, in accordance with procedures prescribed by the
         Committee, to direct the Trustee as to the investment of assets in his
         Accounts. Effective January 1, 1999, any such investment direction by a
         Participant, Former Participant, or Beneficiary shall consist solely of
         the right to direct the extent to which assets shall be invested in the
         following investment media: (i) an equity fund consisting of the common
         stock of the Company; (ii) the Putnam Voyager Fund; and/or (iii) any
         one or more of the funds offered by Chase Bank of Texas, N.A. and known
         as the Chase Vista Prime Money Market Fund I, the Chase Vista U.S.
         Treasury Income Fund A, the Chase Vista Balanced Fund-A, the Chase Core
         Equity Fund and the Chase Vista International Equity Fund A. Effective
         January 1, 1999, (i) each Participant, Former Participant, or
         Beneficiary shall be permitted to indicate the extent to which assets
         shall be invested in accordance with procedures provided by the
         Committee for this purpose, and (ii) subject to such requirements as
         may be necessary to effectuate an orderly transition, a Participant,
         Former Participant, or Beneficiary may elect that allocations to his
         Accounts be invested to a different extent as of any business day
         during a Plan Year. Requests to vary the extent to which allocations
         are to be invested in the above media shall be made in accordance with
         such procedures as the Committee shall prescribe. Should a Participant,
         Former Participant, or Beneficiary fail to provide the Trustee with the
         investment directives described herein, the assets in such individual's
         Accounts shall be invested as determined by the Trustee in accordance
         with the provisions of the Trust Agreement.

<PAGE>   45

         A Participant, Former Participant or Beneficiary is entitled to direct
         the exercise of voting rights with respect to the shares of Company
         common stock allocated to said Participant's (or Former Participant's
         or Beneficiary's) Accounts (with the number of such allocated shares to
         be determined as of any Valuation Date by dividing the then price per
         share into the total value of all shares allocated to such Accounts).
         The Committee shall obtain, as to all such common stock, directions
         from such Participant, Former Participant, or Beneficiary as to how
         said shares are to be voted. The Committee shall furnish such
         directions to the Trustee, who shall then vote the shares accordingly.
         If, however, within a reasonable period of time prior to any meeting of
         stockholders of the Company as may be specified by the Committee, no
         instructions shall have been received by the Committee from such
         Participant(s), Former Participant(s) or Beneficiary(ies), the
         Committee shall instruct the Trustee to vote, in person or by proxy,
         such shares in the manner determined by the Committee in its sole
         discretion.

         The Trustee shall vote any unallocated shares of Company common stock
         held by it pursuant to written directions from the Committee.

7.02     Special Rules for HMGI Stock Fund.

         Notwithstanding the preceding, a Participant's Accounts may be invested
         in an equity fund consisting of the common stock of Halter Marine
         Group, Inc. ("HMGI"). All shares of HMGI common stock (the "HMGI
         Shares") received by the Plan as a result of the Company's distribution
         of HMGI Shares to its shareholders shall be held in a separate equity
         fund (the "HMGI Stock Fund"). For purposes of this Plan, such
         distribution shall be treated as a distribution of income on the shares
         of common stock of the Company held by the Trust. Except as otherwise
         provided in this Section 7.02, the HMGI Shares shall be treated in the
         same manner as shares of the Company's common stock.

         (a)      The HMGI Shares shall be allocated among the Participants'
                  Accounts on a pro-rata basis based on the number of shares of
                  common stock of the Company allocated to each Participant's
                  Accounts as of March 31, 1997; provided, however, that all
                  such allocations shall be in whole shares of HMGI common
                  stock. To the extent that a Participant would be allocated a
                  fractional HMGI Share on March 31, 1997, such fraction will be
                  sold and the proceeds shall be invested in shares of the
                  common stock of the Company.

         (b)      The Trustee shall not purchase any additional HMGI Shares. If
                  the Trustee receives a distribution of cash dividends on the
                  HMGI Shares held in the HMGI Stock Fund, such amounts shall be
                  reinvested as if they were an additional contribution to the
                  Plan in accordance with each Participant's most recent
                  investment election.

         (c)      A Participant may on any business day direct the Trustee to
                  liquidate any portion of his investment in the HMGI Stock Fund
                  and reinvest the proceeds in another investment media;
                  provided, however, that such Participant shall not thereafter
                  be permitted to invest such funds in the HMGI Stock Fund.

                                 ADMINISTRATION

8.01     Allocation of Responsibility Among Fiduciaries for Plan and Trust
         Administration

         The Fiduciaries shall have only those specific powers, duties,
         responsibilities and obligations as are specifically given them under
         this Plan or the Trust. In general, the Employers shall have the sole
         responsibility for making the contributions provided for under Section
         4.01, and the Company shall have the sole authority to appoint and
         remove the Trustee, members of the Committee and any Investment Manager
         which may be provided for under the Trust and to amend or terminate, in
         whole or in part, this Plan or the Trust. The Committee shall have the
         sole responsibility for the administration of this Plan, which
         responsibility is specifically described in this Plan and the Trust.
         The Trustee shall have responsibility for the administration of the
         Trust and the management of the assets held under the Trust, to the
         extent provided in the Trust and Article VII hereof. Each Fiduciary
         warrants that any directions given, information furnished, or actions
         taken by it shall be in accordance with the provisions of the Plan or
         the Trust, as the case may be, authorizing or providing for such
         direction, information or action. Furthermore, each Fiduciary may rely
         upon any such direction, information or action of another Fiduciary as
         being proper under this Plan or the Trust, and is not required under
         this Plan or the Trust to inquire into the propriety of any such
         direction, information or action. It is intended under this Plan and
         the Trust that each Fiduciary shall be responsible for the proper
         exercise of its own powers, duties, responsibilities and obligations
         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.

8.02     Appointment of Committee

         The Plan shall be administered by a Profit Sharing Committee consisting
         of at least three persons who shall be appointed by and serve at the
         pleasure of the Board of Directors of the Company. All usual and
         reasonable expenses of the Committee may be paid in whole or in part by
         the Employers, and any expenses not paid by the Employers shall be paid
         by the Trustee out of the principal or income of the Trust Fund. Any
         members of the Committee who are Employees shall not receive
         compensation with respect to their services for the Committee.

8.03     Claims Procedure

         The Committee shall make all determinations as to the right of any
         person to a benefit. Any denial by the Committee of a claim for
         benefits under the Plan by a Participant, Former Participant, or
         Beneficiary shall be stated in writing by the Committee and delivered
         or mailed to the Participant, Former Participant, or Beneficiary; and
         such notice shall set forth the specific reasons for the denial,
         written to the best of the Committee's ability in a manner that may be
         understood without legal or actuarial counsel. In addition, the
         Committee shall afford a reasonable opportunity to any Participant,

8.04     Records and Reports

         The Committee shall exercise such authority and responsibility as it
         deems appropriate in order to comply with ERISA and governmental

         which are nonforfeitable under the Plan; notifications to Participants
         and Former Participants; annual registration with the Internal Revenue

8.05     Other Committee Powers and Duties

         The Committee shall have such duties and powers as may be necessary to
         discharge its responsibilities hereunder, including, but not by way of
         limitation, the following:

         (a)      to construe and interpret the Plan, decide all questions of
                  eligibility and determine the amount, manner and time of
                  payment of any benefits hereunder;

         (b)      to prescribe procedures to be followed by Participants, Former

         (c)      to prepare and distribute, in such manner as the Committee
                  determines to be appropriate, information explaining the Plan;

         (d)      to receive from the Employers and from Participants or Former
                  Participants such information as shall be necessary for the
                  proper administration of the Plan;

         (e)      to furnish the Employer, upon request, such annual reports
                  with respect to the administration of the Plan as are
                  reasonable and appropriate;

         (f)      to receive, review and keep on file (as it deems convenient or
                  proper) reports of the financial condition, and of the
                  receipts and disbursements, of the Trust Fund from the
                  Trustee; and

         (g)      to appoint or employ individuals to assist in the
                  administration of the Plan and any other agents it deems
                  advisable, including legal and actuarial counsel, the Trustee
                  or any other Fiduciary.

         Subject to the right of the Committee to amend the Plan pursuant to the
         last paragraph of Section 3.01 hereof, the Committee shall have no
         power to add to, subtract from or modify any of the terms of the Plan,
         or to change or add to any benefits provided by the Plan, or to waive
         or fail to apply any requirements of eligibility for a benefit under
         the Plan.

8.06     Rules and Decisions

         The Committee may adopt such rules as it deems necessary, desirable, or
         appropriate. All rules and decisions of the Committee shall be
         uniformly and consistently applied to all


                                       47

<PAGE>   48

         Participants and Former Participants in similar circumstances. When
         making a determination or calculation, the Committee shall be entitled
         to rely upon information furnished by a Participant, Former
         Participant, or Beneficiary, the Employers, the legal counsel of the
         Employers, or the Trustee.

8.07     Committee Procedures

         The Committee may act at a meeting or in writing without a meeting. The
         Committee shall elect one of its members as chairman, appoint a
         secretary, who may or may not be a Committee member, and advise the
         Trustee of such actions in writing. The secretary shall keep a record
         of all meetings and forward all necessary communications to the
         Employers or the Trustee. The Committee may adopt such bylaws and
         regulations as it deems desirable for the conduct of its affairs. All
         decisions of the Committee shall be made by the vote of the majority
         including actions in writing taken without a meeting. A dissenting
         Committee member who, within a reasonable time after he has knowledge
         of any action or failure to act by the majority, registers his dissent
         in writing delivered to the other Committee members, the Employers and
         the Trustee, shall not be responsible for any such action or failure to
         act.

8.08     Authorization of Benefit Payments

         The Committee shall issue directions to the Trustee concerning all
         benefits which are to be paid from the Trust Fund pursuant to the
         provisions of the Plan, and warrants that all such directions are in
         accordance with this Plan.

8.09     Application and Forms for Benefits

         The Committee may require a Participant or Former Participant to
         complete and file with the Committee an application for a benefit and
         all other forms approved by the Committee, and to furnish all pertinent
         information requested by the Committee. The Committee may rely upon all
         such information so furnished it, including the Participant's (or
         Former Participant's) current mailing address. The failure by a
         Participant or Former Participant to file a claim for benefits will not
         result in the forfeiture of any benefits which are otherwise
         nonforfeitable under this Plan.

8.10     Facility of Payment

         Whenever, in the Committee's opinion, a person entitled to receive any
         payment of a benefit or installment thereof hereunder is under a legal
         disability or is incapacitated in any way so as to be unable to manage
         his financial affairs, the Committee may direct the Trustee to make
         payments to such person or to his legal representative or to a relative
         or friend of such person for his benefit, or the Committee may direct
         the Trustee to apply the payment for the benefit of such person in such
         manner as the Committee considers advisable. Any payment of a benefit
         or installment thereof in accordance with the provisions of this
         Section shall be a complete discharge of any liability for the making
         of such payment under the provisions of the Plan.

8.11     Indemnification

         The Employers shall indemnify and hold harmless each member of the
         Committee against all loss, cost, expenses or damages, including
         attorneys' fees and court costs: (a) occasioned by any act or omission
         to act in connection with the responsibility of such member for the
         administration of this Plan; or (b) arising under or by virtue of the
         provisions of Part 4, Subtitle B, Title I of ERISA; provided, however,
         that the Employers shall not indemnify and hold harmless any such
         member against any loss, cost, expenses and damages occasioned by the
         gross negligence or willful misconduct of such member.

8.12     Unclaimed Benefits

         During the time when a benefit hereunder is payable to any Participant,
         Former Participant, or Beneficiary, the Committee, upon request by the
         Trustee, or at its own instance, shall mail by registered or certified
         mail to such Participant, Former Participant, or Beneficiary, at his
         last known address, a written demand for his then address and for
         satisfactory evidence of his continued life, or both. If such
         information is not furnished to the Committee within twelve (12) months
         from the mailing of such demand, then the Committee may, in its sole
         discretion, declare such benefit, or any unpaid portion thereof,
         suspended, with the result that such unclaimed benefit shall be treated
         as a Forfeiture for the Year within which such twelve (12) month period
         ends, but shall be subject to restoration through an Employer
         contribution if the lost Participant, Former Participant, or
         Beneficiary later files a claim for such benefit.

                                   ARTICLE IX

                                  MISCELLANEOUS

9.01     Nonguarantee of Employment

         Nothing contained in this Plan shall be construed as a contract of
         employment between any Employer and any Employee, or as a right of any
         Employee to be continued in the employment of any Employer, or as a
         limitation on the right of an Employer to discharge any of its
         Employees, with or without cause.

9.02     Rights to Trust Assets

         No Employee or Beneficiary shall have any right to, or interest in, any
         assets of the Trust Fund upon termination of his employment or
         otherwise, except as provided from time to time under this Plan, and
         then only to the extent of the benefits payable under the Plan to such
         Employee out of the assets of the Trust Fund. All payments of benefits
         as provided for in this Plan shall be made solely out of the assets of
         the Trust Fund and none of the Fiduciaries shall be liable therefor in
         any manner.

9.03     Nonalienation of Benefits

         Except as provided below, no Participant, Former Participant or
         Beneficiary shall have the right to anticipate, assign, alienate,
         charge, encumber, sell or transfer any benefit provided under the Plan,
         and the Trustee will not recognize any anticipation, assignment,
         alienation, charge, sale or transfer. Furthermore, a benefit under the
         Plan shall not be subject to attachment, charge, encumbrance,
         garnishment, levy, execution or other legal or equitable process. The
         foregoing restrictions shall not apply in the following case(s):

         (a)      Participant Loans. If a Participant, Former Participant or
                  Beneficiary who has become entitled to receive payment of
                  benefits under this Agreement is indebted to the Trustee by
                  virtue of a participant loan the Committee may direct the
                  Trustee to pay the indebtedness and charge it against the
                  account balance of the Participant, Former Participant or
                  Beneficiary.

         (b)      Distributions Under Domestic Relations Orders. Nothing
                  contained in this Plan shall prevent the Trustee, under the
                  direction of the Committee, from complying with the provisions
                  of a qualified domestic relations order, as defined in Code
                  Section 414(p).

         (c)      Distributions Under Certain Judgments and Settlements. Nothing
                  contained in this Plan shall prevent the Trustee from
                  complying with a judgment or settlement which requires the
                  Trustee to reduce a Participant's benefits under the Plan by
                  an amount that the Participant is ordered or required to pay
                  to the Plan if each of the following criteria are satisfied:

                   (1)     The order or requirement must arise-

                           (A)      under a judgment or conviction for a crime
                                    involving the Plan;

                           (B)      under a civil judgment (including a consent
                                    order or decree) entered by a court in an
                                    action brought in connection with an actual
                                    or alleged violation of Part 4 of Title I of
                                    ERISA; or

                           (C)      under a settlement agreement with either the
                                    Secretary of Labor or the Pension Benefit
                                    Guaranty Corporation and the Participant in
                                    connection with an actual or alleged
                                    violation of Part 4 of Title I of ERISA by a
                                    fiduciary or any other person.

                   (2)     The decree, judgment, order or settlement must
                           expressly provide for the offset of all or part of
                           the amount ordered or required to be paid to the Plan
                           against the Participant's benefits under the Plan.

                   (3)     To the extent that (i) the survivor annuity
                           requirements of Code Section 401(a)(11) apply to the
                           portion of the Participant's account balance which
                           will be reduced or offset, and (ii) the Participant
                           has a spouse at the time at which the reduction or
                           offset is to be made--

                                    or offset in writing, as witnessed by a
                                    notary public or a plan representative, (ii)
                                    it must be established that such consent may
                                    not be obtained for any of the reasons
                                    outlined in Code Section 417(a)(2)(B), or
                                    (iii) the spouse must previously have
                                    executed an election to waive his or her
                                    right to a qualified joint and survivor
                                    annuity or a qualified preretirement annuity
                                    in accordance with the requirements of Code
                                    Section 417(a);

                                    must require the spouse to pay an amount to
                                    the Plan in connection with a violation of
                                    Part 4 of Title I of ERISA; or

                           (C)      the decree, judgment, order or settlement
                                    must provide that the spouse shall retain
                                    his or her right to receive a survivor
                                    annuity calculated as provided in Code

         increase in the wage base under such Title II occurring after the date
         of such Participant's termination of employment.

                        AMENDMENTS AND ACTION BY EMPLOYER

10.01    Amendments

         The Company reserves the right to make from time to time any amendment
         or amendments to this Plan which do not cause any part of the Trust
         Fund to be used for, or diverted to, any purpose other than the
         exclusive benefit of Participants, Former Participants, or their
         Beneficiaries; provided, however, that the Company may make any
         amendment it determines necessary or desirable with or without
         retroactive effect, to comply with ERISA. In addition, no amendment
         hereof, unless made to secure the approval of the Internal Revenue
         Service or other governmental bureau or agency shall operate
         retroactively to reduce or divest the then vested interest hereunder of
         any Participant, Former Participant, or Beneficiary or to reduce or
         divest any benefit payable hereunder unless all Participants, Former
         Participants, and Beneficiaries then having vested interests or benefit
         payments affected thereby shall consent to such amendment.

10.02    Action by Employer

         Any action by an Employer under this Plan may be by resolution of its
         Board of Directors, or by any person or persons duly authorized by
         resolution of said Board to take such action.

11.01    Successor Employer

         In the event of the dissolution, merger, consolidation or
         reorganization of an Employer, provisions may be made by which the Plan
         and Trust will be continued by the successor; and, in that event, such
         successor shall be substituted for the Employer under the Plan. The
         substitution of the successor shall constitute an assumption of Plan
         liabilities by the successor and the successor shall have all of the
         powers, duties and responsibilities of the Employer under the Plan.

11.02    Plan Assets

         In the event of any merger or consolidation of the Plan with, or
         transfer in whole or in part of the assets and liabilities of the Trust
         Fund to, another trust fund held under any other plan of deferred
         compensation maintained or to be established for the benefit of all or
         some of the Participants of this Plan, the assets of the Trust Fund
         applicable to such Participants shall be transferred to the other trust
         fund only if:

         (a)      each Participant would (if either this Plan or the other plan
                  then terminated) receive a benefit immediately after the
                  merger, consolidation or transfer which is equal to or


                                       52

<PAGE>   53

                  greater than the benefit he would have been entitled to
                  receive immediately before the merger, consolidation or
                  transfer (if this Plan had then terminated);

         (b)      resolutions of the Board of Directors of the Employer under
                  this Plan, or of any new or successor employer of the affected
                  Participants, shall authorize such transfer of assets; and, in
                  the case of a new or successor employer of the affected
                  Participants, its resolutions shall include an assumption of
                  liabilities with respect to such Participants' inclusion in
                  the new employer's plan; and

         (c)      such other plan and trust are qualified under Sections 401(a)
                  and 501(a) of the Code.

         In accordance with the procedures set forth in this Article, the
         Company may terminate the Plan at any time. In addition, each
         Participating Employer may, at any time, discontinue its participation
         in the Plan, in which event the Plan shall be considered terminated as
         to such Participating Employer. In the event of the dissolution,
         merger, consolidation or reorganization of an Employer, the Plan shall
         terminate with respect to such Employer unless the Plan is continued by
         a successor to the Employer in accordance with Section 11.01.

12.02    Partial Termination

         Upon termination of the Plan with respect to a group of Participants
         which constitutes a partial termination of the Plan, the Trustee shall,
         in accordance with the directions of the Committee, allocate and
         segregate for the benefit of the Participants with respect to whom the
         Plan is being terminated the proportionate interest of such
         Participants in the Trust Fund. The funds so allocated and segregated
         shall be used by the Trustee to pay benefits to or on behalf of
         Participants in accordance with Section 12.03. The termination of
         active participation by those individuals described in Addendum A shall
         not constitute a partial termination of the Plan.

12.03    Liquidation of the Trust Fund

         Upon complete or partial termination of the Plan, the accounts of all
         Participants affected thereby shall become fully vested, and the
         Committee shall direct the Trustee to distribute the assets remaining
         in the Trust Fund, after payment of any expenses properly chargeable
         thereto, to Participants, Former Participants and Beneficiaries in
         proportion to their respective account balances.

12.04    Manner of Distribution

         Distributions after termination of the Plan shall be made in a form and
         manner consistent with the provisions of Section 6.04 hereof.

         3. Effective as of December 1, 1999, Section 5.02 of the Plan is hereby
amended by adding the following new paragraph (e) to the end thereof to be and
read as follows:

         "(e)  Stock Units--The Committee shall permit a Participant to
               designate that all or any portion of his Account balances be
               treated as invested in Stock Units as of December 1, 1999 or as
               of the last day of each succeeding month (or if no shares of the
               Company's common stock are traded on such date, as of the
               immediately preceding trading date). For purposes of calculating
               the number of Stock Units deemed credited to a Participant's
               Accounts pursuant to this Section, the price of a Stock Unit
               shall be equal to one hundred percent (100%) of the closing price
               of a share of the Company's common stock on the date on which the
               Stock Units are deemed credited to the Participant's Accounts (or
               if no shares of the Company's common stock are traded on such
               date, on the immediately preceding trading date). To the extent
               that Stock Units are allocated to a Participant's Accounts, the
               following additional provisions shall apply.

               (1)  Voting Rights. A Participant shall not be entitled to any
                    voting rights with respect to the Stock Units deemed
                    credited to his Accounts.

               (2)  Dividends. To the extent that a dividend is paid on the
                    Company's common stock, the Committee shall credit to the
                    Accounts of each Participant whose Accounts are deemed
                    invested in Stock Units an amount equal to the value of such
                    dividends. Such amounts shall be credited to a Participant's
                    Accounts in the form of additional Stock Units at a price
                    equal to one hundred percent (100%) of the closing price of
                    a share of the Company's common stock on the date on which
                    such dividend is paid (or if no shares of the Company's
                    common stock are traded on such date, on the immediately
                    preceding trading date).

               (3)  Dilution and Other Adjustments. In the event of any change
                    in the outstanding shares of common stock of the Company by
                    reason of any stock dividend, split, spin-off,
                    recapitalization, merger, consolidation, combination,
                    extraordinary dividend, exchange of shares or other similar
                    change, the Committee shall adjust the number or kind of
                    Stock Units then deemed allocated to the Participants'
                    Accounts as follows:

                    (a)  Subject to any required action by stockholders, the
                         number of Stock Units shall be proportionately adjusted
                         for any increase or decrease in the number of issued
                         shares of the Company's common stock resulting from (i)
                         a subdivision or consolidation of shares, (ii) the
                         payment of a stock dividend or (iii) any other increase
                         or decrease in the number of shares effected without
                         receipt of consideration by the Company.

                    (b)  In the event of a change in the shares of the Company's
                         common stock as presently constituted, which is limited
                         to a change of par

                         value into the same number of shares with a different
                         par value or without par value, the shares of the
                         Company's common stock resulting from any such change
                         shall be deemed to be the shares of common stock within
                         the meaning of this Plan.

                    Any adjustments made by the Committee pursuant to this
                    subparagraph (3) shall be final, binding, and conclusive.

                    Except as hereinbefore provided in this Section, a
                    Participant to whose Account Stock Units are allocated shall
                    have no rights by reason of (i) any subdivision or
                    consolidation of the Company's stock or securities, (ii) the
                    payment of any stock dividend or (iii) any other increase or
                    decrease in the number of shares of stock of any class or by
                    reason of any dissolution, liquidation, reorganization,
                    merger, or consolidation or spinoff of assets or stock of
                    another corporation, and any issuance by the Company of
                    additional shares of stock (of any class), or securities
                    convertible into shares of stock (of any class), shall not
                    affect the number of Stock Units allocated to such
                    Participant's Accounts under this Plan."

         4. Effective as of December 1, 1999, Section 6.01 of the Plan is hereby
amended by adding the following new paragraph (d) to the end of the first
paragraph thereof, to be and read as follows:

         "(d)  Payments shall be made in cash or, to the extent that any amount
               to be distributed has been deemed invested in Stock Units, in
               common stock of the Company; provided that any amount deemed
               invested in fractional shares shall, in all events, be paid in
               cash."

                    employment prior to the Effective Date, the rights and
                    benefits, if any, of such former Employee shall be
                    determined in accordance with the provisions of the Prior
                    Plan, as in effect on the date on which his employment
                    terminated.

                            PARTICIPATION AND SERVICE

3.01              Participation

                  An Employee who was a Participant under the Prior Plan shall
                  continue as a Participant under this Plan, to the extent
                  provided hereunder. All references hereunder to such
                  Participant's "compensation reduction agreement" shall include
                  his salary reduction agreement executed under the Prior Plan.

                  An individual classified as an Employee under Section 2.01(v)
                  hereof shall become a Participant in this Plan on the first
                  day of (i) the month on or immediately following such
                  classification or (ii) any of his taxable years thereafter,
                  provided that, prior to such date, he shall first have
                  undertaken the actions specified in Section 3.03 hereof.

                  An active Participant who incurs a Severance from Service and
                  who is subsequently reemployed by an Employer shall reenter
                  the Plan as an active Participant on his Reemployment
                  Commencement Date or the first day of any of his next
                  following taxable years, but only if (i) he continues to
                  qualify as an Employee within the meaning of Section 2.01(v)
                  hereof and (ii) prior to such date he shall have again
                  undertaken the actions specified in Section 3.03 hereof. In
                  the event that a Participant shall cease to qualify as an
                  Employee within the meaning of Section 2.01(v) hereof, his
                  Participation shall thereupon cease but he shall continue to
                  accrue Service hereunder during the period of his continued
                  employment with the Employers.

                  Any provisions of this Plan to the contrary notwithstanding,
                  effective on and after the date of a Change in Control, the
                  term "Participant" shall be limited to those individuals who
                  satisfy the requirements set forth for participation in this
                  Plan and who were Participants in this Plan as of the date
                  immediately prior to the date of such Change in Control.

                           Elapsed-Time Employment. Service shall be counted in
                           years and completed days.

                           Employee who at any time was employed by an Affiliate
                           either commences employment with a Participating
                           Employer, or returns to the employment of a
                           Participating Employer, then, except as otherwise
                           provided below, such Employee shall receive Service
                           with respect to the period of his employment with

                           paragraph (c) of this Section). In applying the
                           provisions of the preceding sentence--

                           (1)      except to the extent otherwise permitted by
                                    the Committee in its sole discretion, such
                                    Employee shall not receive Service with
                                    respect to any period of employment with

                                    on which such Affiliate became an Affiliate;

                           (2)      the amount of such Service shall be
                                    determined in accordance with paragraph (a)
                                    of this Section, as if such Affiliate were a
                                    Participating Employer; and

                           (3)      if such Employee incurs a Break in Service
                                    (as defined in paragraph (d) of this Section
                                    and determined as if such Affiliate were a
                                    Participating Employer) prior to his
                                    commencement of employment with the
                                    Participating Employer or return to the
                                    employment of the Participating Employer,
                                    then the amount of such Employee's Service
                                    attributable to the period of his employment
                                    with such Affiliate shall be determined in
                                    accordance with paragraph (d) of this
                                    Section.

                  (c)      Transfers to Affiliate. In the event that a
                           Participant who at any time was employed by a
                           Participating Employer either commences employment
                           with an Affiliate, or returns to the employment of an
                           Affiliate, then, except as otherwise provided below,
                           such Participant shall receive Service with respect
                           to the period of his employment with such Affiliate
                           (to the extent not credited under paragraph (b) of
                           this Section). In applying the provisions of the
                           preceding sentence--

                           (1)      the amount of such Service shall be
                                    determined in accordance with paragraph (a)
                                    of this Section, as if such Affiliate were a
                                    Participating Employer; and

                           (2)      if such Participant incurs a Break in
                                    Service (as defined in paragraph (d) of this
                                    Section and determined as if such Affiliate
                                    were a Participating Employer) prior to his
                                    commencement of employment with the
                                    Affiliate or return to the employment of the
                                    Affiliate, then

                                    the amount of such Participant's Service
                                    attributable to his prior period of
                                    employment with the Participating Employer
                                    shall be determined  in accordance with
                                    paragraph (d) of this Section.

                    (d)  Break in Service. An Employee who incurs a Severance
                         from Service and who fails to complete at least one (1)
                         Hour of Employment during the twelve (12)-month period
                         beginning on the date of such Severance from Service
                         shall have a Break in Service. If, during the twelve
                         (12)-month period beginning on the date of an
                         Employee's Severance from Service, the Employee shall
                         return to the employment of a Participating Employer by
                         completing at least one (1) Hour of Employment within
                         such twelve (12)-month period, then such Employee will
                         not have a Break in Service and shall receive Service
                         for the period beginning on the date of his Severance
                         from Service and ending on the date of his
                         reemployment; provided, however, that in the case of an
                         Employee who is absent from the employment of the
                         Participating Employers for a reason specified in
                         Section 2.01(ll)(1)(ii) hereof and who, prior to the
                         first anniversary of the first date of such absence,
                         incurs a Severance from Service for a reason specified
                         in Section 2.01(ll)(1)(i) hereof, such Employee shall
                         receive Service only if he completes at least one (1)
                         Hour of Employment within the twelve (12)-month period
                         beginning on the first date of such absence and shall
                         receive such Service only for the period beginning on
                         the first day of such absence and ending on the date of
                         his reemployment. Upon incurring a Break in Service, an
                         Employee's rights and benefits under the Plan shall be
                         determined in accordance with his Service at the time
                         of the Break in Service. For a Participant who, at the
                         time of a Break in Service, satisfied any requirements
                         of this Plan for vested benefits, his pre-break Service
                         shall, upon his Reemployment Commencement Date, be
                         restored in determining his rights and benefits under
                         the Plan. For an Employee who, at the time of a Break
                         in Service, had not fulfilled such requirements,
                         periods of pre-break Service shall, upon his
                         Reemployment Commencement Date, be restored only if the
                         consecutive periods of Break in Service were less than
                         the greater of (i) sixty (60) months or (ii) the total
                         period of pre-break Service.

                    (e)  Special Rule for Participants After Initial Eligibility
                         Date. Notwithstanding the preceding provisions of this
                         Section 3.02, the Elapsed-Time Employment and Service
                         of any Participant who failed to elect to participate
                         hereunder pursuant to Section 3.03 hereof prior to the
                         date on which he was first eligible to do so pursuant
                         to Section 3.01 hereof shall be determined as if his
                         Employment Commencement Date were the later of (i) the
                         Initial Effective Date or (ii) the date on which he
                         first completes an Hour of Employment. In addition, in
                         the case of a Participant who was not employed by an
                         Employer on the Initial Effective Date but was so
                         employed prior to such date, such prior period of
                         employment will not, under any circumstances, be
                         treated as Service unless such Participant elects to
                         participate hereunder pursuant to such Section 3.03
                         prior to the date on which he was first eligible to do
                         so pursuant to such Section 3.01.

                    (f)  Special Rule for Extended Absence Employees.
                         Notwithstanding the preceding provisions of this
                         Section 3.02, in the case of an Extended

                         Absence Employee, the period between the first and
                         second anniversaries of such Employee's absence shall,
                         under no circumstances, be treated as a period of
                         Service.

3.03              Election to Participate

                  In order to participate hereunder, an Employee, otherwise
                  eligible to participate pursuant to Section 3.01 hereof, must,
                  after having received a written explanation of the terms of
                  and the benefits provided under the Plan, elect to participate
                  in such Plan on such form or forms as the Committee may
                  provide and must execute a compensation reduction agreement
                  described in Section 4.02 hereof. Such election to participate
                  and execution of a compensation reduction agreement shall be
                  effected on any date on or prior to the applicable date
                  specified in such Section 3.01 for the commencement of
                  Participation and, in all events, prior to the completion of
                  services for which amounts subject to the compensation
                  reduction agreement would otherwise have been paid to such
                  Employee.

3.04              Transfer

                  An Employee who is transferred between Participating Employers
                  shall be as eligible for Participation and benefits as in the
                  absence of such transfer.

5.02              Investment of Accounts

                  (a)    Participant Election. The Committee shall credit each
                         Participant's Accounts with earnings or losses
                         according to the hypothetical investment selections
                         made by the Participant pursuant to his participation
                         agreement executed pursuant to Section 3.03 hereof. The
                         Committee shall adopt rules concerning the manner in
                         which a Participant may elect to change his
                         hypothetical investment selections; provided that a
                         Participant shall be permitted to do so no less
                         frequently than as of the first day of each month;

                         a Participant's Accounts shall be determined as if the
                         amounts credited to such Accounts


                                       14

                         were actually invested in Stock Units, to the extent
                         required or elected hereunder, and, to the extent not
                         so required or elected, in the hypothetical investments
                         selected under the Participant's participation
                         agreement. In the case of a Participant receiving
                         installment payments under Article VI hereof, the
                         Participant's Accounts will continue to receive

                         this subsection until his Accounts are paid in full. If
                         a Participant's participation agreement fails to
                         designate one or more hypothetical investment
                         selections, the Participant's Account will be deemed
                         invested in Stock Units, to the extent required
                         hereunder, and, to the extent not so required, in the
                         investment option designated as having the least
                         investment risk.

                    (b)  Investment Options. The Committee shall have sole and
                         absolute discretion with respect to the number and

                         selection by Participants pursuant to this Section, the
                         timing of Participant elections and the method by which
                         adjustments are made. The Committee may in its sole
                         discretion refuse to recognize Participant elections
                         that it determines may cause the Participant's Accounts
                         to become subject to the short-swing profit provisions
                         of Section 16b of the Securities Exchange Act of 1934
                         and establish special election procedures for
                         Participants subject to Section 16 of such Act. The
                         Committee shall permit Participants to designate that
                         their investments be treated as invested in (i) Stock
                         Units or (ii) one or more investment indices; provided
                         that amounts credited on or after the Effective Date to
                         a Participant's Matching Contribution Account or
                         Additional Matching Contribution Account shall at all
                         times be invested in Stock Units; provided further that
                         Compensation Reduction Contributions made on or after
                         the Effective Date of Award Compensation shall at all
                         times be invested in Stock Units. The designation of
                         investment options by the Committee shall be for the
                         sole purpose of adjusting Accounts pursuant to this
                         Section and, except to the extent that investment in
                         Stock Units is required hereunder, the provisions of
                         this Article V shall not obligate the Company or any of
                         the Employers to invest or set aside any assets for the
                         payment of benefits hereunder; provided, however, that
                         the Company or an Employer may invest a portion of its
                         general assets in investments, including investments
                         which are the same as or similar to the investment
                         indices designated by the Committee and selected by
                         Participants, but any such investments shall remain
                         part of the general assets of the Company or such
                         Employer and shall not be deemed or construed to grant
                         a property interest of any kind to any Participant,
                         designated Beneficiary or estate. The Committee shall
                         notify the Participants of the investment indices
                         available and the procedures for making and changing
                         elections.

                    (c)  Non-Binding Status of Elections. A Participant's
                         hypothetical investment selections pursuant to the
                         immediately preceding paragraph shall be made solely
                         for purposes of crediting earnings and/or losses to his
                         Accounts under Section 5.03 of this Plan. The Committee
                         shall not, in any way, be bound to actually invest any
                         amounts set aside pursuant to Article VII below to
                         satisfy its obligations under this Plan in accordance
                         with such selections.

5.03              Account Adjustments

                  The accounts of Participants, Former Participants and
                  Beneficiaries shall be adjusted in accordance with the
                  following:

                  (a)    Valuation Adjustments. As of each Valuation Date, the
                         amount credited to a Participant's Accounts as of the
                         preceding Valuation Date, less any distributions or
                         Forfeitures with respect to such Accounts since such
                         preceding Valuation Date, shall be adjusted by
                         reference to the fluctuations in value, taking into
                         account gain, loss, expenses and other adjustments, of
                         the investments selected by the Participant for the
                         investment adjustment of his or her Accounts, with such
                         adjustments to be made in the manner prescribed by the
                         Committee. Following such adjustment, the amounts
                         credited to a Participant's Accounts shall be increased
                         to take into account additional deferrals and
                         contributions credited to such Accounts since the
                         preceding Valuation Date.

                  (b)    Compensation Reduction Contributions. The amount
                         credited pursuant to Section 4.01(a) hereof for a Year
                         as a Compensation Reduction Contribution shall be
                         allocated to the Participant's Compensation Reduction
                         Contribution Account as of the date on which such
                         Compensation Reduction Contribution would otherwise
                         have been paid to the Participant as Compensation.

                  (c)    Matching Contributions. Any Stock Units credited to a
                         Participant by an Employer pursuant to Section 4.01(b)
                         or (c) during a Year shall be allocated, as the case
                         may be, to the Participant's Matching Contribution
                         Account or the Participant's Additional Matching
                         Contribution Account at such time as may be determined
                         by the Employer in its absolute discretion, but no
                         earlier than the last day of such Year.

                  (d)    Discretionary Contributions. Any amounts credited to a
                         Participant by an Employer pursuant to Section 4.01(e)
                         during a Year shall be allocated to the Participant's
                         Discretionary Contribution Account at the time
                         determined by the Employer in its absolute discretion.

5.04              Stock Units

                  (a)    General. For purposes of calculating the number of
                         Stock Units credited or deemed credited to a
                         Participant's Accounts pursuant to Section 5.03 (b) or
                         (d), the price of a Stock Unit shall be equal to one
                         hundred percent (100%) of the closing price on the New
                         York Stock Exchange of a share of the Company's common
                         stock on the date on which the Stock Units are credited
                         or deemed credited to the Participant's Accounts (or if
                         no shares of the Company's common stock are traded on
                         such date, on the immediately preceding trading date).
                         For purposes of calculating the number of Stock Units
                         credited to a Participant's Accounts pursuant to
                         Section 5.02 (c), the price of a Stock Unit shall be
                         equal to one hundred percent (100%) of the average
                         daily closing price on the New York Stock Exchange of a
                         Share of the Company's common stock for the Year with
                         respect to which the Stock Units are credited to the
                         Participant's Accounts,


                                       16

<PAGE>   21

                         provided, that for Stock Units credited with respect to
                         the year ending March 31, 2000, such average daily
                         closing price shall be calculated for the period
                         beginning on January 1, 2000 and ending on such March
                         31, 2000.

                  (b)    Voting Rights. A Participant shall not be entitled to
                         any voting rights with respect to the Stock Units
                         credited or deemed credited to his Accounts.

                  (c)    Dividends. To the extent that a dividend is paid on the
                         Company's common stock, the Committee shall credit to
                         the Accounts of each Participant whose Accounts are
                         invested or deemed invested in Stock Units an amount
                         equal to the value of such dividends. Such amounts
                         shall be credited to the Participant's Accounts in the
                         form of additional Stock Units at a price equal to one
                         hundred percent (100%) of the closing price on the New
                         York Stock Exchange of a share of the Company's common
                         stock on the date on which such dividend is paid (or if
                         no shares of the Company's common stock are traded on
                         such date, on the immediately preceding trading date).

                  (d)    Dilution and Other Adjustments. In the event of any
                         change in the outstanding shares of common stock of the
                         Company by reason of any stock dividend, split,
                         spin-off, recapitalization, merger, consolidation,
                         combination, extraordinary dividend, exchange of shares
                         or other similar change, the Committee shall adjust the
                         number or kind of Stock Units then allocated or deemed
                         allocated to the Participants' Accounts as follows:

                         (1)  Subject to any required action by stockholders,
                              the number of Stock Units shall be proportionately
                              adjusted for any increase or decrease in the
                              number of issued shares of the Company's common
                              stock resulting from (i) a subdivision or
                              consolidation of shares, (ii) the payment of a
                              stock dividend or (iii) any other increase or
                              decrease in the number of shares effected without
                              receipt of consideration by the Company.

                         (2)  In the event of a change in the shares of the
                              Company's common stock as presently constituted,
                              which is limited to a change of par value into the
                              same number of shares with a different par value
                              or without par value, the shares of the Company's
                              common stock resulting from any such change shall
                              be deemed to be the shares of common stock within
                              the meaning of this Plan.

                         Any adjustments made by the Committee pursuant to this
                         Section 5.04 shall be final, binding, and conclusive.

                         Except as hereinbefore provided in this Section 5.04, a
                         Participant to whose Account Stock Units are allocated
                         shall have no rights by reason of (i) any subdivision
                         or consolidation of the Company's stock or securities,
                         (ii) the payment of any stock dividend or (iii) any
                         other increase or decrease in the number of shares of
                         stock of any class or by reason of any dissolution,
                         liquidation, reorganization, merger, or consolidation
                         or spinoff of assets or stock of another corporation,
                         and any issuance by the Company of additional shares of
                         stock (of any class), or securities


                                       17

                         convertible into shares of stock (of any class), shall
                         not affect the number of Stock Units allocated to such
                         Participant's Accounts under this Plan.

                                   ARTICLE VI

                            DISTRIBUTION OF BENEFITS

6.01              General

                  Within thirty (30) days following the termination of a
                  Participant's employment, the Committee (i) shall certify to
                  the Trustee or the Treasurer of the Employer, as applicable,
                  the total amount of the allocations to the credit of the
                  Participant on the books of each Employer by which the
                  Participant was employed at a time when amounts were credited
                  by such Employer to his Accounts and the Participant's
                  nonforfeitable interest in such Accounts, and (ii) shall
                  determine whether the payment of the amounts credited to the
                  Participant's Accounts under the Plan is to be paid directly
                  by the applicable Employer, from the Trust Fund, or by a
                  combination of such sources (except to the extent that the
                  provisions of the Trust specify payment from the Trust Fund).

6.02              Payments of Benefits

                  Payment of the nonforfeitable portion of the amounts credited
                  to a Participant's Accounts shall be made in accordance with
                  the following provisions:

                  (a)      Death, Disability or Retirement. Payments made with
                           respect to a Participant's termination of employment
                           on account of death, Disability or "retirement" (as
                           defined in the Trinity Industries, Inc. Standard
                           Pension Plan), shall be made in such form as the
                           Participant may elect from the following
                           alternatives:

                           (1)      In a lump sum;

                           (2)      In annual periodic payments for a specified
                                    number of years, not in excess of 20, with
                                    the first payment to be made no later than
                                    the sixtieth (60th) day following the date
                                    on which the Participant's termination of
                                    employment occurs and subsequent payments to
                                    be made in the same calendar quarter of each
                                    succeeding year, where the payment made
                                    during each year shall be in an amount equal
                                    to a fraction of the Participant's Account
                                    balances as of the last day of the calendar
                                    quarter preceding the calendar quarter in
                                    which the payment is made, and where such
                                    fraction for each payment shall be one (1)
                                    divided by the number of payments remaining
                                    (including the current payment), and in
                                    which event the unpaid balance shall
                                    continue to be adjusted as provided in
                                    Section 5.03(a) until it is distributed in
                                    full; or

                           (3)      In any combination of the methods specified
                                    in subparagraphs (1) or (2) of this
                                    paragraph (a).

                           Any election pursuant to this paragraph (a) must be
                           made prior to the date on which such Employee's
                           Participation hereunder first commences, with all
                           payments to be made in the form of a lump sum in the
                           absence of a timely election and, except as expressly
                           provided otherwise in this Plan, shall be
                           irrevocable; provided, however, that a Participant
                           may change such election once during any Year, with
                           the new election to be effective for a distribution
                           arising from termination of employment of the
                           Participant only if such distribution is to be made
                           or commence for more than twelve (12) months after
                           the date of the new election. The Committee shall, as
                           of the last day of the calendar quarter within which
                           the Participant terminates employment, certify to the
                           Trustee or the Treasurer of the Employer, as

                           Participant.

                  (b)      Termination of Employment. Payments with respect to a
                           Participant's termination of employment for reasons
                           other than death, Disability or "retirement" (as
                           defined in the Trinity Industries, Inc. Standard
                           Pension Plan) shall be made in the form of a lump
                           sum.

                  (c)      Prior Plan Elections. Notwithstanding the preceding
                           provisions of this Section 6.02 and with respect to
                           an Employee who became a Participant in the Prior
                           Plan before the Effective Date, such Participant's
                           election with respect to the form of payment made
                           pursuant to the provisions of the Prior Plan shall
                           remain in effect unless changed by the Participant in
                           the manner and to the extent described in paragraph
                           (a) above.

                  (d)      Timing. Payment of amounts credited to a
                           Participant's Accounts must be made or commence by no
                           later than the sixtieth (60th) day following the date
                           on which the Participant's termination of employment
                           occurs.

                  The Trustee (to the extent provided in the Trust) or the
                  Treasurer of the Employer, as applicable, shall thereafter
                  make payments of benefits in the manner and at the times
                  specified above, subject, however, to all of the other terms
                  and conditions of this Plan and the Trust. This Plan shall be
                  deemed to authorize the payment of all or any portion of a
                  Participant's benefits from the Trust Fund to the extent such
                  payment is required by the provisions of the Trust. Payments
                  shall be made in cash or, to the extent that any amount to be
                  distributed has been invested or deemed invested in Stock
                  Units, in common stock of the Company; provided that any
                  amount invested or deemed invested in fractional shares shall,
                  in all events, be paid in cash.

                           of employment is attributable to his death or
                           Disability, he shall be entitled to the entire amount
                           then credited to his Accounts.

                           Disability, he shall be entitled to the entire amount
                           then credited to his Compensation Reduction

                  (2)      Additional Matching Contribution Account. If a
                           Participant's termination of employment is not
                           attributable to his death or Disability, he shall be
                           entitled to all amounts credited to his Additional
                           Matching Contribution Account for more than two (2)
                           calendar years following the end of the calendar year
                           in which occurs the allocation of the Compensation
                           Reduction Contribution with respect to which such
                           Additional Matching Contributions were made;
                           provided, however, that if the Participant terminates
                           employment by reason of retirement on or after age
                           sixty-five (65), the Committee may, in its sole
                           discretion, authorize a distribution of the entire
                           amount credited to his Additional Matching
                           Contribution Account; provided further, that if such
                           termination of employment occurs on or after a Change
                           in Control, the Participant shall be entitled to the
                           entire amount credited to his Additional Matching
                           Contribution Account.

                  (3)      Other Accounts. If a Participant's termination of
                           employment is not attributable to his death or
                           Disability, he shall be entitled to a "vested
                           percentage" of the amounts credited to his Matching
                           Contribution Account and Discretionary Contribution
                           Account, if any, based on his years of Service as

                           ; provided, however, that if the Participant
                           terminates employment by reason of retirement on or
                           after age sixty-five (65), the Committee may, in its
                           discretion, authorize up to full vesting of the
                           entire amount credited to such Accounts; provided,
                           further, that if such termination of employment
                           occurs on or after a Change in Control, the
                           Participant shall under all circumstances be entitled
                           to the entire amount credited to such Accounts.
                           Notwithstanding the preceding provisions of this
                           subparagraph (3), for amounts credited to a
                           Participant's Matching Contribution Account and
                           Discretionary Contribution Account, if any, pursuant
                           to the terms of the Prior Plan, if the Participant's
                           termination of employment is attributable to
                           retirement on or after age sixty-five (65), he shall
                           under all circumstances be entitled to one hundred

                           the Year of termination of employment but not yet
                           allocated.

6.04              Death

                  If a Participant shall die while in the service of an
                  Employer, or after termination of employment with the
                  Employers and prior to the complete distribution of all
                  amounts payable to him under the Plan, any remaining amounts
                  payable to the Participant hereunder shall be payable to his
                  Beneficiary. The Committee shall cause the Trustee (to the
                  extent provided in the Trust) or the Treasurer of the
                  Employer, as applicable, to pay to such Beneficiary all of the
                  amounts then standing to the credit of the Participant in his
                  Accounts, with such payment to be made at the time and in the
                  manner specified in Section 6.02 hereof.

6.05              Plan Termination

                  If the Plan is terminated pursuant to the provisions of
                  Article X hereof, the Committee shall cause the Trustee or the
                  Treasurer of the Employer, as applicable, to pay to all
                  Participants all of the amounts then standing to their credit,
                  with payment to be made at the time and in the manner
                  specified in Section 6.02 hereof; provided, however, that if
                  the Plan is terminated on or after a Change in Control,
                  payment shall be made in the form of a lump sum which shall be
                  paid no later than sixty (60) days following the date on which
                  the Plan termination occurs, or, if elected by the Participant
                  at least one full year prior to the date on which payment
                  otherwise would have been made upon termination of the Plan,
                  payment may be made in the form of five annual installments,
                  with the first installment to be made no later than sixty (60)
                  days following the date on which the termination occurs and
                  the remaining installments to be paid no later than the last
                  day of February of the next four successive calendar years.
                  Each installment shall be in an amount equal to a fraction of
                  the total balance in the Participant's Accounts as of the end
                  of the immediately preceding calendar quarter, where the
                  fraction shall be one (1) divided by the number of
                  installments remaining to be paid (including the current
                  installment), and where the unpaid balance shall continue to
                  be adjusted as provided in Section 5.03(a) until it is
                  distributed in full.

6.06              Designation of Beneficiary

                  Each Participant from time to time may designate any person or
                  persons (who may be designated contingently or successively
                  and who may be an entity other than a natural person) as his
                  Beneficiary or Beneficiaries to whom his Plan benefits are
                  paid if he dies before receipt of all such benefits. Each
                  Beneficiary designation shall be on a form prescribed by the
                  Committee and will be effective only when filed with the
                  Committee during the Participant's lifetime. Each Beneficiary
                  designation filed with the Committee will cancel all
                  Beneficiary designations previously filed with the Committee.
                  The revocation of a Beneficiary designation, no matter how
                  effected, shall not require the consent of any designated
                  Beneficiary.

                  If any Participant fails to designate a Beneficiary in the
                  manner provided herein, or if the Beneficiary designated by a
                  deceased Participant dies before him or before complete
                  distribution of the Participant's benefits, the Committee, in
                  its sole discretion, may direct the Trustee to distribute such
                  Participant's benefits (or the balance thereof) to his
                  surviving spouse or to either:


                                       21

<PAGE>   26

                  (a)    any one or more of the next of kin of such Participant,
                         and in such proportions as the Committee determines; or

                  (b)    the estate of the last to die of such Participant and
                         his Beneficiary or Beneficiaries.

6.07              In-Service Distributions

                  No amounts credited to a Participant's Accounts shall be
                  distributed to or on behalf of the Participant prior to the
                  occurrence of one of the events specified in the provisions of
                  this Article VI except as follows:

                  (a)    A distribution may be made to or on behalf of the
                         Participant to the extent that the Committee, in its
                         sole discretion, consents to such distribution upon a
                         showing, by the Participant, of an unforeseeable
                         emergency. For this purpose, an "unforeseeable
                         emergency" is defined as severe financial hardship to
                         the Participant resulting from a sudden and unexpected
                         illness or accident of the Participant or of a
                         dependent of the Participant, loss of the Participant's
                         property due to casualty, or other similar
                         extraordinary and unforeseeable circumstances arising
                         as a result of events beyond the control of the
                         Participant. The circumstances that will constitute an
                         unforeseeable emergency will depend on the facts of
                         each case, but payment may not be made to the extent
                         that such hardship is or may be relieved--(i) through
                         reimbursement or compensation by insurance or
                         otherwise, (ii) by liquidation of the Participant's
                         assets, to the extent that the liquidation of such
                         assets would not itself cause severe financial
                         hardship, or (iii) by cessation of deferrals under the
                         Plan.

                  (b)    A lump sum distribution may be made to or on behalf of
                         a Participant at any time, but no more often than once
                         during any Year, of an amount equal to at least 25% of
                         the Participant's nonforfeitable Account balances, and
                         in such proportions from each such Account as the
                         Participant may request; provided, however, that (i) an
                         amount equal to 10% of the amount distributed from the
                         Accounts of a Participant pursuant to this paragraph
                         shall be forfeited in the same proportion from such
                         Accounts at the time of the distribution so that the
                         amount distributed to the Participant pursuant to this
                         paragraph shall never exceed the amount of the
                         Participant's nonforfeitable Account balances minus the
                         amount so forfeited, and (ii) the compensation
                         reduction agreement of any Participant who receives a
                         distribution pursuant to this paragraph shall be
                         suspended for one full year from the date of such
                         distribution.

6.08              Designated Distributions

                  Prior to the beginning of a calendar year, a Participant may
                  elect that all or any portion of the amount of any
                  Compensation Reduction Contribution to be credited to the
                  Participant's Compensation Reduction Contribution Account
                  during such calendar year, be distributed to or on behalf of
                  the Participant in the form of a lump sum in a subsequent
                  calendar year designated by the Participant, which subsequent
                  calendar year shall not be earlier than the third calendar
                  year following the calendar

                  year for which the election is made. The distribution shall
                  be made no later than March 31 of the designated year. In
                  the event of the Participant's termination of employment for
                  any reason prior to the designated year, the election shall
                  be void and of no effect.

                             NATURE OF PLAN; FUNDING


7.01              No Trust Required

                  The adoption of this Plan and any setting aside of amounts by
                  the Employers with which to discharge their obligations
                  hereunder shall not be deemed to create a trust; legal and
                  equitable title to any funds so set aside shall remain with
                  the Employers, and any recipient of benefits hereunder shall
                  have no security or other interest in such funds. Any and all
                  funds so set aside shall remain subject to the claims of the
                  general creditors of the Employers, present and future. This
                  provision shall not require the Employers to set aside any
                  funds, but the Employers may set aside funds if they choose to
                  do so.

7.02              Funding of Obligation

                  Section 7.01 above to the contrary notwithstanding, the
                  Employers may elect to transfer assets to the Trust, the
                  provisions of which shall at all times require the use of the
                  Trust's assets to satisfy claims of an Employer's general
                  unsecured creditors in the event of such Employer's insolvency
                  and direct that no Participant shall at any time have a prior
                  claim to such assets. The assets of the Trust shall not be
                  deemed to be assets of this Plan.

                                  ARTICLE VIII

                                 ADMINISTRATION

8.01              Appointment of Committee

                  The Board of Directors of the Company shall appoint a Plan
                  Committee to administer, construe and interpret the Plan. Such
                  Committee, or such successor Committee as may be duly
                  appointed by such Board of Directors, shall serve at the
                  pleasure of the Board of Directors. All usual and reasonable
                  expenses of the Committee shall be paid by the Employers.
                  Decisions of the Committee with respect to any matter
                  involving the Plan shall be final and binding on the Company,
                  its shareholders, each Employer and all officers and other
                  executives of the Employers. For purposes of ERISA, the
                  Committee shall be the Plan "administrator" with respect to
                  the general administration of the Plan.

8.02              Duties of Committee

                  The Committee shall maintain complete and adequate records
                  pertaining to the Plan, including but not limited to
                  Participants' Accounts, amounts transferred to the Trust,
                  reports from the Trustee and all other records that shall be
                  necessary or desirable in


                                       23

<PAGE>   28

                  the proper administration of the Plan. The Committee shall
                  furnish the Trustee such information as is required to be
                  furnished by the Committee or the Company pursuant to the
                  Trust. The Committee may employ such persons or appoint such
                  agents to assist it in the performance of its duties as it
                  may deem appropriate. If a member of the Committee is a
                  Participant hereunder, such Committee member shall be
                  precluded from participation in any decision relative to his
                  benefits under the Plan.

8.03              Indemnification of Committee

                  The Company (the "Indemnifying Party") hereby agrees to
                  indemnify and hold harmless the members of the Committee (the
                  "Indemnified Parties") against any losses, claims, damages or
                  liabilities to which any of the Indemnified Parties may become
                  subject to the extent that such losses, claims, damages or
                  liabilities or actions in respect thereof arise out of or are
                  based upon any act or omission of the Indemnified Party in
                  connection with the administration of this Plan (other than
                  any act or omission of such Indemnified Party constituting
                  gross negligence or willful misconduct), and will reimburse
                  the Indemnified Party for any legal or other expenses
                  reasonably incurred by him or her in connection with
                  investigating or defending against any such loss, claim,
                  damage, liability or action. Promptly after receipt by the
                  Indemnified Party of notice of the commencement of any action
                  or proceeding with respect to any loss, claim, damage or
                  liability against which the Indemnified Party believes he or
                  she is indemnified, the Indemnified Party shall, if a claim
                  with respect thereto is to be made against the Indemnifying
                  Party, notify the Indemnifying Party in writing of the
                  commencement thereof; provided, however, that the omission so
                  to notify the Indemnifying Party shall not relieve it from any
                  liability which it may have to the Indemnified Party to the
                  extent the Indemnifying Party is not prejudiced by such
                  omission. If any such action or proceeding shall be brought
                  against the Indemnified Party, and it shall notify the
                  Indemnifying Party of the commencement thereof, the
                  Indemnifying Party shall be entitled to participate therein,
                  and, to the extent that it shall wish, to assume the defense
                  thereof, with counsel reasonably satisfactory to the
                  Indemnified Party, and, after notice from the Indemnifying
                  Party to the Indemnified Party of its election to assume the
                  defense thereof, the Indemnifying Party shall not be liable to
                  such Indemnified Party for any legal or other expenses
                  subsequently incurred by the Indemnified Party in connection
                  with the defense thereof other than reasonable costs of
                  investigation or reasonable expenses of actions taken at the
                  written request of the Indemnifying Party. The Indemnifying
                  Party shall not be liable for any compromise or settlement of
                  any such action or proceeding effected without its consent,
                  which consent will not be unreasonably withheld.

8.04              Unclaimed Benefits

                  During the time when a benefit hereunder is payable to any
                  Participant or Beneficiary, the Committee may, at its own
                  instance, mail by registered or certified mail to such
                  Participant or Beneficiary, at his last known address, a
                  written demand for his then address, or for satisfactory
                  evidence of his continued life, or both. If such information
                  is not furnished to the Committee within twelve (12) months
                  from the mailing of such demand, then the Committee may, in
                  its sole discretion, declare such benefit, or any unpaid
                  portion thereof, suspended, with the result that such


                                       24

<PAGE>   29

                  unclaimed benefit shall be treated as a Forfeiture for the
                  Year with or within which such twelve (12)-month period ends,
                  but shall be subject to restoration through an Employer
                  contribution if the lost Participant or Beneficiary later
                  files a claim for such benefit.

                                   ARTICLE IX

                                  MISCELLANEOUS

9.01              Nonguarantee of Employment

                  Nothing contained in this Plan shall be construed as a
                  contract of employment between any Employer and any Employee,
                  or as a right of any Employee to be continued in the
                  employment of any Employer, or as a limitation on the right of
                  an Employer to discharge any of its Employees, with or without
                  cause.

9.02              Nonalienation of Benefits

                  Benefits payable under this Plan shall not be subject in any
                  manner to anticipation, alienation, sale, transfer,
                  assignment, pledge, encumbrance, charge, garnishment,
                  execution, or levy of any kind, either voluntary or
                  involuntary, prior to actually being received by the person
                  entitled to the benefit under the terms of the Plan; and any
                  attempt to anticipate, alienate, sell, transfer, assign,
                  pledge, encumber, charge or otherwise dispose of any right to
                  benefits payable hereunder shall be void.

9.03              No Preference

                  No Participant shall have any preference over the general
                  creditors of an Employer in the event of such Employer's
                  insolvency.

9.04              Incompetence of Recipient

                  If the Committee receives evidence satisfactory to it that any
                  person entitled to receive a payment hereunder is, at the time
                  the benefit is payable, physically, mentally or legally
                  incompetent to receive such payment and to give a valid
                  receipt therefor, and that an individual or institution is
                  then maintaining or has custody of such person and that no
                  guardian, committee or other representative of the estate of
                  such person has been duly appointed, the Committee may direct
                  that such payment be paid to such individual or institution
                  maintaining or having custody of such person, and the receipt
                  of such individual or institution shall be valid and a
                  complete discharge for the payment of such benefit.

9.05              Texas Law to Apply

                  THIS PLAN SHALL BE CONSTRUED AND ENFORCED UNDER THE LAWS OF
                  THE STATE OF TEXAS EXCEPT TO THE EXTENT PREEMPTED BY FEDERAL
                  LAW.

9.06              Claims Procedure/Arbitration

                  If any person (hereinafter called the "Claimant") feels that
                  he or she is being denied a benefit to which he or she is
                  entitled under this Plan, such Claimant may file a written
                  claim for said benefit with the Committee. Within sixty (60)
                  days following the receipt of such claim the Committee shall
                  determine and notify the Claimant as to whether he or she is
                  entitled to such benefit. Such notification shall be in
                  writing and, if denying the claim for benefit, shall set forth
                  the specific reason or reasons for the denial, make specific
                  reference to the pertinent provisions of this Plan, and advise
                  the Claimant that he or she may, within sixty (60) days
                  following the receipt of such notice, in writing request to
                  appear before the Committee or its designated representative
                  for a hearing to review such denial. Any such hearing shall be
                  scheduled at the mutual convenience of the Committee or its
                  designated representative and the Claimant, and at any such
                  hearing the Claimant and/or his or her duly authorized
                  representative may examine any relevant documents and present
                  evidence and arguments to support the granting of the benefit
                  being claimed. The final decision of the Committee with
                  respect to the claim being reviewed shall be made within sixty
                  (60) days following the hearing thereon, and the Committee
                  shall in writing notify the Claimant of said final decision,
                  again specifying the reasons therefor and the pertinent
                  provisions of this Plan upon which said final decision is
                  based. The final decision of the Committee shall be conclusive
                  and binding upon all parties having or claiming to have an
                  interest in the matter being reviewed.

                  Any dispute or controversy arising out of, or relating to, the
                  payment of benefits pursuant to this Plan shall be settled by
                  arbitration in Dallas, Texas (or, if applicable law requires
                  some other forum, then such other forum) in accordance with
                  the rules then obtaining of the American Arbitration
                  Association. The District Court of Dallas County, Texas or, as
                  the case may be, the United States District Court for the
                  Northern District of Texas shall have jurisdiction for all
                  purposes in connection with any such arbitration. Any process
                  or notice of motion or other application to either of said
                  courts, and any paper in connection with arbitration, may be
                  served by certified mail, return receipt requested, or by
                  personal service or in such other manner as may be permissible
                  under the rules of the applicable court or arbitration
                  tribunal, provided a reasonable time for appearance is
                  allowed. Arbitration proceedings must be instituted within one
                  (1) year after the claimed breach occurred, and the failure to
                  institute arbitration proceedings within such period shall
                  constitute an absolute bar to the institution of any
                  proceedings, and a waiver of all claims, with respect to such
                  breach.

9.07              Reimbursement of Costs

                  In the event that a dispute arises between a Participant or
                  Beneficiary and the Company or other Employer with respect to
                  the payment of benefits hereunder, and attorney's fees,
                  expenses and costs are incurred by either party in the course
                  of litigation or otherwise, the party against whom the other
                  party has been successful in such dispute shall reimburse such
                  other party for the full amount of any such attorneys' fees,
                  expenses and costs.

9.08              Acceleration of Payment

                  In the event that the Internal Revenue Service formally
                  assesses a deficiency against a Participant on the grounds
                  that an amount credited to such Participant's Accounts under
                  this Plan is subject to Federal income tax (the "Reclassified
                  Amount") earlier than the time payment otherwise would be made
                  to the Participant pursuant to this Plan, then the Committee
                  shall direct the Employer maintaining such Participant's
                  Accounts to pay to such Participant and deduct from such
                  Account the Reclassified Amount.

                                    ARTICLE X

                        AMENDMENTS OR TERMINATION OF PLAN

         The Board of Directors of the Company shall have the power and right
from time to time to modify, amend, supplement, suspend or terminate the Plan as
it applies to each Employer, provided that no such change in the Plan may
deprive a Participant of the amounts allocated to his or her accounts or be
retroactive in effect to the prejudice of any Participant.

         Any provision of this Plan to the contrary notwithstanding, no action
to modify, amend, supplement, suspend or terminate the Plan on or after the date
of a Change in Control shall be effective without the consent of a majority of
the Participants in the Plan at the time of such action.

                                   ARTICLE XI

                WITHDRAWING EMPLOYERS; TRANSFER TO SUCCESSOR PLAN

11.01             Withdrawing Employers

                  In the event that a Participating Employer elects to
                  discontinue or revoke its participation in this Plan:

                  (a)    the Company shall cause to be prepared a new plan (the
                         "Successor Plan") for the withdrawing Participating
                         Employer, the terms of which shall be identical to the
                         terms of this Plan;

                  (b)    the Company shall transfer, deliver and assign any and
                         all benefit obligations under this Plan which relate to
                         Participants who are employees of the withdrawing
                         Participating Employer or its subsidiaries to the
                         Successor Plan; and

                  (c)    the withdrawing Participating Employer shall be deemed
                         to have consented to the adoption of the Successor
                         Plan.

                  For purposes of this provision, the Successor Plan shall treat
                  all benefit obligations described under (b) above as if they
                  had accrued due to an individual's service with the

                  Any provision of this Plan to the contrary notwithstanding, in
                  the event that:

                  (a)    the employment of a Participant with the Company or
                         other Participating Employer is terminated in
                         connection with the sale, spin-off or other disposition
                         of a direct or indirect subsidiary of the Company or a
                         sale or other disposition of assets of the Company or
                         the assets of a direct or indirect subsidiary of the
                         Company (the "Transaction");

                  (b)    in connection with the Transaction, such terminated
                         Participant becomes employed by the subsidiary that is
                         sold, spun-off or otherwise disposed of, the purchaser
                         of the subsidiary or assets or other surviving entity
                         in the Transaction, as the case may be, or an affiliate
                         thereof, (the "Successor Employer"); and

                  (c)    in connection with and effective as of or prior to the
                         closing of the Transaction, the Successor Employer
                         establishes a new plan, the terms of which are
                         substantially identical to the terms of this Plan and
                         which treat all benefit obligations which relate to the
                         Participant (including those transferred to the
                         Successor Plan pursuant to the provisions of this
                         Section) as if they had accrued due to the
                         Participant's service with the Successor Employer (the

                  then the Participant shall not be entitled to a distribution
                  of benefits from this Plan on account of such termination of
                  employment, and the Company or other Participating Employer
                  which formerly employed the Participant and which maintains an
                  Account or Accounts for such Participant under this Plan shall
                  transfer, deliver and assign to the Successor Plan and
                  Successor Employer as of the date the Participant becomes
                  employed by the Successor Employer any and all benefit
                  obligations under this Plan which relate to the Participant,
                  and effective with and subsequent to the adoption of the
                  Successor Plan by the Successor Employer and the transfer of
                  the Participant's benefit obligations from this Plan to the
                  Successor Plan, the Participant whose benefits were
                  transferred to the Successor Plan shall not be entitled to
                  receive any amounts from this Plan which relate to benefit
                  obligations which accrued prior to the transfer. The preceding
                  provisions to the contrary notwithstanding, the provisions of
                  this Section 11.02 shall not be effective for Transactions
                  that occur on or after the date of a Change in Control without
                  the written consent of a majority of the Participants in the
                  Plan at such time.
