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

         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

         The amount of benefit payable to or on behalf of a Participant shall be
         determined on the basis of his period of Service, in accordance with
         the following:

         (a)      In General. Subject to the Break in Service provisions of
                  paragraph (d) of this Section, an Employee's Service shall
                  equal the total of his Elapsed-Time Employment. Service shall
                  be counted in years and completed days.

         (b)      Transfers from Affiliates. In the event that an 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 such
                  Affiliate (to the extent not credited under 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 such Affiliate completed prior to the
                           date 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



                                       9
   10

                           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



                                       10
   11
                  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.

                  with an amount agreed to be credited by such Employer pursuant
                  to a compensation reduction agreement entered into between the
                  Employer and the Participant for such Year, as provided in
                  Section 4.02; provided that if such Participant is also a
                  participant in the Profit Sharing Plan for Employees of

                  Participant must first have elected to contribute the maximum
                  permissible salary reduction contribution for the Year to his
                  salary reduction contribution account under such Profit
                  Sharing Plan, with such maximum permissible amount to be
                  determined by reference to all applicable limitations of (i)

                  percentage of that portion of the Participant's Compensation
                  Reduction Contribution for such Year pursuant to Section 4.02
                  hereof which does not exceed six percent (6%) of his Base
                  Compensation plus Annual Incentive Compensation for such Year,
                  based on his years of Service as follows:



                   Years of Service                   Applicable Percentage
                   ----------------                   ---------------------
                                                   
                   Less than 1                                     0%
                   1 but less than 2                              25%
                   2 but less than 3                              30%
                   3 but less than 4                              35%

                   5 or more                                      50%


         (c)      Additional Matching Contribution. For each Year, each Employer
                  shall credit an additional amount in the form of Stock Units
                  to each of its Employees for whom an amount was credited
                  pursuant to paragraph (a) of this Section 4.01, which when
                  added to the Forfeitures which have become available for
                  application as of the end of the Year pursuant to Section 4.03
                  hereof and which have not been applied as provided in
                  paragraph (b) of this Section, shall be equal to seventeen and
                  one-half percent (17 1/2%) of that portion of the
                  Participant's Compensation Reduction Contribution for such
                  Year pursuant to Section 4.02 hereof which is invested or
                  deemed invested in Stock Units pursuant to Section 5.02(a)
                  hereof up to twenty-five percent (25%) of the sum of his Base
                  Compensation and Annual Incentive Compensation for such Year.

         (d)      Limitations on Matching Contributions. Except in the case of a
                  Participant who "retires" (as defined in the Trinity
                  Industries, Inc. Standard Pension Plan), dies or incurs a
                  Disability during a Year, no Matching Employer Contributions
                  shall be credited to a Participant for a Year unless such
                  Participant is actively employed by an Employer on the last
                  day of such Year. In addition, no Matching Employer
                  Contributions or Additional Matching Contributions shall be
                  credited to Participants for a Year unless the Company's
                  earnings per share for such Year are sufficient to cover
                  dividends to stockholders; provided that in no event will a
                  Matching Employer Contribution or Additional Matching
                  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. In addition, and notwithstanding paragraph (b) of
                  this Section, the amount of Matching Employer Contribution
                  credited to a Participant for a Year under this Plan shall be
                  reduced by the amount of any matching contribution credited to
                  the


                                       12

   13




                  Participant for such Year under the Profit Sharing Plan for
                  Employees of Trinity Industries, Inc. and Certain Affiliates.


         (e)      Discretionary Contributions. In addition to the contributions
                  described above, for each Year an Employer may, but shall not
                  be required to, credit the Discretionary Contribution Account
                  of any one or more Participants in its employ during such Year
                  with such amounts in the form of Stock Units or otherwise as
                  the Employer may determine in its sole discretion.

4.02     Participant Compensation Reduction

         (a)      General. Prior to commencement of Participation hereunder, a
                  Participant shall have entered into a written compensation
                  reduction agreement with his Employer. The terms of such
                  compensation reduction agreement shall provide that the
                  Participant agrees to accept a reduction in Compensation from
                  the Employer. In consideration of such agreement, the Employer
                  will credit the Participant's Compensation Reduction
                  Contribution Account for each Year with an amount equal to the
                  total amount by which the Participant's Compensation from the
                  Employer was reduced during the Year pursuant to the
                  compensation reduction agreement.

         (b)      Election Requirements. Compensation reduction agreements shall
                  be further governed by the following:

                  (1)      A compensation reduction agreement shall specify the
                           types of Compensation to which it will apply and
                           shall be effective during the period in which it is
                           on file with the Participant's Employer, but in no
                           event shall be effective to (i) reduce Award
                           Compensation which is attributable to the exercise of
                           nonqualified stock options, the lapse of all
                           restrictions on a grant of restricted stock, the
                           exercise of stock appreciation rights or the payment
                           of dividend equivalent rights and which is payable
                           during the six (6) month period immediately following
                           the date of execution of the agreement; or (ii)
                           reduce payments of Base Compensation, Annual
                           Incentive Compensation or other types of Award
                           Compensation for services completed on or before the
                           date on which such compensation reduction agreement
                           is received by the Corporate Benefits department of
                           the Company.

                  (2)      A compensation reduction agreement shall have been
                           entered into by a Participant on or prior to
                           commencement of Participation hereunder and shall
                           remain in effect until terminated or amended by the
                           Participant in accordance with the procedures set
                           forth herein. Any amendment or termination of a
                           compensation reduction agreement shall not be
                           effective until the first day of the Participant's
                           taxable year immediately following the taxable year
                           of the Participant in which an election so to amend
                           or terminate is executed by the Participant and his
                           Employer and must be received by the Corporate
                           Benefits department of the Company at least fifteen
                           (15) days prior to the end of the taxable year of
                           execution. If a Participant

                                       13


   14




                           terminates his compensation reduction agreement as
                           hereinabove provided, then he may elect to enter into
                           another compensation reduction agreement to be
                           effective as of the first day of any of his taxable
                           years following his taxable year in which such
                           termination was first effective, provided that
                           written notice of such election must be received by
                           the Corporate Benefits department of the Company at
                           least fifteen (15) days prior to such effective date.
                           Notwithstanding the preceding provisions of this
                           subparagraph (2), to the extent that a compensation
                           reduction agreement reduces Award Compensation
                           described in subparagraph (1)(i) of this paragraph
                           (b), such agreement shall at all times be
                           irrevocable.

4.03     Forfeitures

         If, upon a Severance from Service, a Participant is not entitled to a
         distribution of the entire balance in his Matching Contribution
         Account, Additional Matching Contribution Account and/or Discretionary
         Contribution Account, then the amount to which the Participant is not
         entitled shall become a Forfeiture and shall be deducted from the
         Participant's Accounts at such time. The portion of the Participant's
         Accounts which is not a Forfeiture shall continue to be adjusted as
         provided in Section 5.03(a) until it is distributed in full. The
         Participant shall receive a distribution of the nonforfeitable portion
         of his Accounts pursuant to Article VI.

                                    ARTICLE V

                      ALLOCATIONS TO PARTICIPANTS' ACCOUNTS

5.01     Individual Accounts

         The Committee shall create and maintain adequate records to disclose
         the interest hereunder 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 shall have up to four
         separate Accounts, a Compensation Reduction Contribution Account, a
         Matching Contribution Account, an Additional Matching Contribution
         Account, and a Discretionary Contribution Account.

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; provided further, that
                  a Participant may not change the hypothetical election which
                  applies to any portion of his Accounts that is invested or
                  deemed to be invested in Stock Units. The earnings or losses
                  attributable to a Participant's Accounts shall be determined
                  as if the amounts credited to such Accounts

                                       14


   15






                  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
                  allocations of earnings or losses in accordance with 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 types of investment
                  options made available for 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 5.03 (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


   17






                  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


   18




                  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).


                                       18


   19






                  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 applicable, the method of payment selected
                  by the 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.

6.03     Vesting of Benefits

         (a)      Death or Disability. If a Participant's termination of
                  employment is attributable to his death or Disability, he
                  shall be entitled to the entire amount then credited to his
                  Accounts.

         (b)      Termination of Employment. (1) Compensation Reduction
                  Contribution Account. If a Participant's termination of
                  employment is not attributable to his death or Disability, he
                  shall be entitled to the entire amount then credited to his
                  Compensation Reduction Contribution Account.


                                       19

   20






         (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 amounts credited to his
                  Additional Matching Contribution Account to the extent that
                  there have elapsed at least two (2) Plan Years following the
                  end of the Plan Year for which the Additional Matching
                  Contribution was 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
                  follows:



                                                       Vested                   Forfeited
                   Years of Service                  Percentage                 Percentage

                   1 but less than 2                      20%                       80%
                   2 but less than 3                      40%                       60%
                   3 but less than 4                      60%                       40%

                  ; 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
                  percent (100%) of such amounts.

         (d)      Amount Credited. For purposes of this Section, the amount
                  credited to a Participant's Accounts at termination of
                  employment shall include any amounts to be credited pursuant
                  to Section 4.01 hereof for 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
   22


         (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


                                       22
   23


         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.

                                   ARTICLE VII

                             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
   24


         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
   25


         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.


                                       25
   26


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.


                                       26
   27


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 withdrawing Participating
         Employer. Subsequent to the withdrawing Participating Employer's
         adoption of the Successor Plan, and the transfer of benefit obligations
         from this Plan to the Successor Plan, Participants whose benefits were


                                       27
   28


         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.

11.02    Transfer to Successor Plan

         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 "Successor Plan"),
                  and a new rabbi trust, the terms of which are substantially
                  identical to the terms of the Trust (the "Successor Trust"),

         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
