Notwithstanding the preceding provisions of this Section 3.01, 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.

After having received a written explanation of the terms of and the benefits provided under the Plan, each eligible Employee shall become a Participant only after he or she (i) elects to participate in the Plan on such form or forms as the Committee may provide and (ii) executes a Compensation Reduction Agreement in accordance with the terms of this Section 3.02; provided, however, that in all respects, the Committee may prescribe the appropriate administrative procedures relating to the time and form of deferral elections to be made by a Participant, including without limitation such procedures, which limit the “window” during which such elections may be made.

(a)Compensation Reduction Contribution Elections.

(1)Deferrals of Base Compensation. With respect to deferrals of Base Compensation, a Participant must file a Compensation Reduction Agreement with the Administrator within the time period established by the Administrator, but in all events no later than the close of the calendar

year immediately preceding the calendar year in which the services to which the Agreement relates are performed. In the Plan Year in which an Employee is first eligible to participate in the Plan, he or she must file a Compensation Reduction Agreement with the Administrator within thirty (30) days after such eligibility is determined, and his or her election will relate only to Base Compensation earned after his or her initial Compensation Reduction Agreement is effective.

(2)Deferrals of Annual Incentive Compensation. With respect to deferrals of Annual Incentive Compensation which is Performance-Based Compensation, a Participant must file a Compensation Reduction Agreement with the Administrator no later than six months before the end of the period in which the services to which the Agreement relates are performed, and provided further that in no event may an election to defer Performance Based Compensation be made after such compensation has become readily ascertainable. With respect to deferrals of Annual Incentive Compensation which is not Performance-Based Compensation, the Participant must file a Compensation Reduction Agreement with the Administrator no later than the close of the calendar year immediately preceding the calendar year in which the services to which the Agreement relates are performed. The Committee may require elections made with respect to Annual Incentive Compensation be submitted no later than the close of the calendar year immediately preceding the calendar year in which the services to which the Agreement relates are performed, regardless of whether it meets the requirements of Performance-Based Compensation.

(3)Duration of Compensation Deferral Election.

(i)For Compensation deferred prior to January 1, 2021,[1] the Participant’s last valid election on file with the Administrator will remain effective and govern the treatment of such amounts (including distribution of such amounts) until subsequently modified or revoked by the Participant; provided, however, that any such election shall, if not otherwise modified by the Participant, be reformed for amounts to be deferred under this Plan on and after January 1, 2021 as follows:

1.To the extent a Participant has made an election directing amounts be paid at his “Retirement” under the Prior Plan, such election shall be reformed under this Plan (until such time as the election is revoked or modified hereunder) to provide that such Participant has made an election to receive a distribution of his amounts on Severance from Service without reference to Retirement; and/or

2.To the extent a Participant has made an election directing payment of amounts in installments over a greater than 10 year period under the Prior Plan, such election shall be reformed under this Plan (until such time as the election is revoked or modified hereunder) to provide that such Participant has made an election to receive a distribution in the form of installments over a period of 10 years.

(ii)Beginning January 1, 2021, a Participant may make a new deferral election for each Plan Year. The timing of such deferral election shall be governed by Sections 3.02(a)(1) and (2) hereof.

Participants shall make the following elections on each appropriate Compensation Reduction Agreement:

(1)The percentage of each eligible component of Compensation to be deferred for the Plan Year;

(2)The desired date of distribution for the deferred amount, pursuant to the terms of Section 6.02.

(3)The form in which payment of any such deferred amounts is to be made to the Participant, pursuant to the terms of Section 6.02; and

(4)The deemed investment of the amounts to be deferred, as provided in Section 5.02.

Any Compensation Reduction Agreement made under this subsection (3) shall be “evergreen” and shall remain in place until such time as the Participant modifies or revokes such election in accordance with the timing requirements specified in this Section 3.02(a).

(b)Distribution Elections. For Compensation deferred prior to January 1, 2021, a Participant may not make an election regarding the date on which payment shall be made or commence or, with certain exceptions, the form in which such distribution shall be paid. Payment will be made or commence on the date and in such form as determined in accordance with the terms of the Prior Plan under which such deferral election was made (and any permitted modification provisions included therein).

The remainder of this subsection (b) shall apply for all Compensation earned and deferred on or after January 1, 2021.

(1)Date on Which Payment is Made or Commences. Participants shall elect to defer his or her Compensation for a Plan Year to (A) a specified date (which shall occur in or after the second Plan Year following the end of the Plan Year to which the Compensation Reduction Agreement relates and be prior to the last day of the tenth Plan Year following such Plan Year), or, (B) subject to the requirements of Section 6.02(b), to the Participant’s termination date

(2)Form of Distribution. The form of distribution of a Participant’s Accounts shall be determined in accordance with the Participant’s election under Section 6.02(a) hereof or, if Section 6.02(b) hereof is applicable, in accordance with such Section 6.02(b). An election regarding the form of distribution of a Participant’s Accounts shall be made by the Participant on the date on which the Participant files his or her initial Compensation Reduction Agreement. The form of payment so elected by the Participant shall be effective as to all Contributions for that Plan Year made by or on behalf of the Participant.

(3)Modifications. Elections related to the form of distribution may be modified only to the extent that such modification is consistent with the requirements of Section 6.02(d) hereof.

(4)Default Elections. If no timely election is made as to the distribution timing and/or form applicable to a deferral election made under Section 3.02(a)(3) (taking into account any deferral election that was retained from a prior Plan Year (as such might be reformed under Section 3.02(a)(3)(i)) for any deferral made on or after January 1, 2021, the Participant will be paid the applicable amount (A) if no distribution form is

selected, in a single lump sum, and/or (B) if no distribution commencement date is selected, subject to the requirements of Section 6.02(b), on Severance from Service.

An active Participant who incurs a Severance from Service and who is subsequently reemployed by an Employer may reenter the Plan as an active Participant on his Reemployment Commencement Date or on 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(w) hereof and (ii) prior to such date he shall have again undertaken the actions specified in Section 3.02(a) and (b) hereof. In the event that a Participant shall cease to qualify as an Employee within the meaning of Section 2.01(w) hereof, his Participation shall thereupon cease but he shall continue to accrue Service hereunder during the period of his continued employment with the Employers.

(d)Special Rule Related To Change in Control. 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.

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--

(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(oo)(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(oo)(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.

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.

Notwithstanding the preceding provisions of this Section 3.03, the Elapsed-Time Employment and Service of any Participant who failed to elect to participate hereunder pursuant to Section 3.02 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 shall not, under any circumstances, be treated as Service unless such Participant elects to participate hereunder pursuant to such Section 3.02 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 3.03, in the case of an Extended Absence Employee,

Employers shall credit Participant Accounts in accordance with the following:

(a)Compensation Reduction Contributions.

Such Compensation Reduction Agreement shall also include a distribution election as provided for under Section 3.02.

(b)Matching Employer Contributions. For each Plan Year, each Employer shall credit a Matching Employer Contribution amount in the form of cash to each of its Employees for whom an amount was credited pursuant to paragraph (a) of this Section 4.01. Such Matching Employer Contribution, when added to the Forfeitures which have become available for application as of the end of the Year pursuant to Section 4.03 hereof, shall be equal to fifty percent (50%) 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.

Matching Employer Contributions shall be distributed at the same time and in the same form as elected by the Participant on the Compensation Reduction Agreement for any deferral amount to which such Matching Employer Contributions relate.

The Board of Directors or the Finance & Risk Committee of the Board of Directors, in its discretion, may elect to waive such earnings requirement. 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 Participant for such Year under the Trinity Industries, Inc. 401(k) Plan.

(d)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 cash as the Employer may determine in its sole

(b)Additional Election Requirements. In addition to the requirements of Section 3.02(a) hereof, 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, the elected distribution form and timing applicable to such amounts contributed to the Plan under the Compensation Reduction Agreement, and shall be effective during the period in which it is on file with the Administrator, but in no event shall such Agreement 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 filed with the Administrator.

(2)A Compensation Reduction Agreement relating to a Plan Year may not be modified or revoked once such Plan Year has commenced except as provided in Section 6.05 hereof following a Participant’s receipt of a Plan distribution due to an Unforeseeable Emergency. Any modification to or termination of a Compensation Reduction Agreement relating to a subsequent Plan Year must be made prior to the close of the calendar year immediately preceding the calendar year in which the services are performed and to which the modified or terminated Agreement relates. If a Participant terminates his Compensation Reduction Agreement as provided above, he may subsequently elect to enter into another Compensation Reduction Agreement, provided that he is at such time an eligible Employee and provided further that such election is made with respect to a succeeding calendar year in accordance with Section 3.02(a) hereof.

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) hereof until it is distributed in full. The Participant shall receive a distribution of the nonforfeitable portion of his Accounts pursuant to Article VI hereof.

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. A Participant shall have appropriate separate Accounts, including a Compensation Reduction Contribution Account, a Matching Contribution Account, an Additional Matching Contribution Account (attributable to Additional Matching Contributions made on behalf of a Participant for Plan Years beginning prior to January 1, 2004) 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 3.02 hereof. In accordance with certain limitations on investment designations in Section 5.02(b) 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. Effective for Plan Years beginning on and after January 1, 2004, the earnings or losses attributable to a Participant’s Accounts shall be determined as if the amounts credited to such Accounts were actually invested in Stock Units, to the extent elected hereunder, and, to the extent not so elected or to the extent prohibited hereunder, 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 shall 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 Accounts will be deemed invested in the investment option designated as having the least investment risk.

(b)On and after January 1, 2004, amounts contributed to a Participant’s Matching Contribution Account, Additional Matching Contribution Account, and Discretionary Contribution Account shall not be treated as invested in Stock Units. In addition, amounts credited to a Participant’s Matching Contribution Account, Additional Matching Contribution Account, or Discretionary Contribution Account and deemed invested in any other media may not, on or after such date, be treated as transferred into or out of deemed investments in Stock Units (except to the extent provided for in Section 5.04). Compensation Reduction Contributions may, at the Participant’s election, be treated as invested in Trinity Stock Units, either at the time such amounts are initially credited to the Participant’s Compensation Reduction Contribution Account or following deemed investment in other media. A Participant shall only hold Arcosa Stock Units as provided for under Exhibit B hereof. Subject to the requirements of Section 5.04, following a deemed investment in Stock Units, such Contributions may not be treated as transferred out of deemed investments in Stock Units.

(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 amounts credited to a Participant by an Employer pursuant to Section 4.01(b) hereof during a Year shall be allocated to the Participant’s Matching Contribution Account at such time as may be determined by the Employer in its absolute discretion.

(d)Discretionary Contributions. Any amounts credited to a Participant by an Employer pursuant to Section 4.01(d) hereof 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. Subject to the discretion of the Committee, one of the ongoing investment alternatives available under this Plan may be investment in Trinity Stock Units. Arcosa Stock Units will be available only for a period of time as contemplated under Exhibit B hereof.

(b)Investment in Stock Units. For purposes of calculating the number of Trinity Stock Units credited or deemed credited to a Participant’s Compensation Reduction Contribution Account pursuant to Section 5.03(b) hereof, the price of a Trinity 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 Trinity 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). Allocations occurring prior to January 1, 2004, shall be calculated as set forth in the Prior Plan document(s) relevant to such periods.

(c)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.

(d)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 in cash equal to the value of such dividends.

(e)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 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.

6.01 General

Within thirty (30) days following the date on which a distribution is to be made under this Article 6, 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

Amounts deferred under this Plan on or before December 31, 2020 shall be governed by the distribution provisions provided for in the Prior Plan except as otherwise specifically noted herein. For purposes of determining the amount of any payment, the Participant’s Account will be valued as provided in an administrative policy adopted by the. Committee. Payment of the nonforfeitable portion of the amounts credited to a Participant’s Accounts shall be made in accordance with the following provisions:

(a)Form. For Compensation deferred after January 1, 2021, Participants shall be entitled to elect the form in which to receive payment of deferred amounts (to the extent vested, with respect to any Discretionary Contributions or Matching Employer Contributions made in the same Plan Year to which a Compensation Reduction Agreement relates), together with earnings accrued thereon in the form of:

(1)In a lump sum; or

(2)In annual periodic payments for the number of years elected by the Participant, not in excess of ten (10). Each payment shall be in an amount equal to a fraction of the Participant’s Account, 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) hereof until it is distributed in full. In accordance with Treasury Regulation Section 1.409A-2(b)(2)(iii) and (iv) and for purposes of Section 6.02(d) hereof, an election for distribution in the form of periodic payments shall be treated as an election of a series of separate payments.

If the Participant fails to elect the method pursuant to which amounts shall be distributed, the Participant shall be deemed to have selected a lump sum distribution form. Within thirty (30) days following a Participant’s Severance from Service, The Committee shall certify to the Trustee or the Treasurer of the Employer, as applicable, the method of payment selected by the Participant.

(b)Timing of Distribution. For Compensation deferred after January 1, 2021, Participants shall, subject to all requirements under Section 6.02(c) below, be entitled to elect to receive payment of deferred amounts (to the extent vested, with respect to any Discretionary Contributions or Matching Employer Contributions made in the same Plan Year to which a Compensation Reduction Agreement relates), together with earnings accrued thereon:

(1)[specified date election] on or beginning on a date specified by the Participant in his or her Compensation Reduction Agreement provided such date shall occur in or after the second Plan Year following the end of the Plan Year to which the Compensation Reduction Agreement relates and is prior to the last day of the tenth Plan Year following such Plan Year; or

(2)[Severance from Service election] on or beginning on the Participant’s Severance from Service

in the form as selected or specified under Section 6.02(a) above. If the Participant fails to elect the date or event on which distribution shall occur, the Participant shall be deemed to have selected a distribution to be paid (or commence on) his Severance from Service.

For clarification purposes only, all distribution amounts due under this Section shall be paid to the Participant in accordance with the terms of the Compensation Reduction Agreement on file and the criteria of this Section 6.02, regardless of employment status on such date (e.g., Severance from Service shall not accelerate distribution to be paid as of a specified date hereunder).

(c)Time Payment is Made or Commences.

(1)Distribution to be paid on a specified date, shall be made or commence on a date that is within ten (10) business days of such specified date. Elections to delay payment beyond such date are permitted on one occasion in accordance with Section 6.02(d) hereof.

(2)If a Participant has a Severance from Service for a reason other than death, payment of all vested amounts credited to a Participant’s Accounts that are to be paid on such Severance from Service shall be made or commence on the first business day following the date that is six months from the date on which the Participant separated from service. Elections to delay payment beyond such date are not permitted.

(3)If a Participant has a Severance from Service , payment of all vested amounts credited to the Participant’s Accounts shall be made or commence sixty (60) days following the date on which the Participant terminates employment as a result of his death.

(4)In the case of annual installment payments, payments made subsequent to the first payment in each succeeding calendar year shall be made in the same calendar quarter as the first payment.

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; provided, however, that the time and form of distribution shall, in all events, be made as otherwise determined under the terms of the Plan. 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, such Stock Units; provided that any amount invested or deemed invested in fractional shares shall, in all events, be paid in cash.

(d)Modification that Changes Form of Payment.

For amounts deferred under this Plan or after January 1, 2021, a modification of a Participant’s previous election related to the timing and/or form of a distribution to be paid under Section 6.02(b)(1) hereof (relating to amounts to be paid on a specified date) is ineffective unless all of the following requirements are satisfied:

(1)Such modification may not be effective for at least twelve (12) months after the date on which the modification is filed with the Administrator.

(2)The modification must provide that payment will not commence for five (5) years from the date payment would otherwise have been made or commenced.

(3)Modifications relating to elections for payment at a specified time or pursuant to a fixed schedule (as described in Treasury Reg. Section 1.409A-3(a)(4)) may not be made less than twelve (12) months prior to the date of the first otherwise scheduled payment (in accordance with Treasury Reg. Section 1.409A-3(j).

(4)Such modification may not permit acceleration of the time or schedule of any payment under the Plan, except as may be permitted pursuant to applicable Treasury Regulations.

A Participant is entitled to modify only a distribution scheduled to be paid on a specified date under Section 6.02(b)(1) and may only make such modification election on one occasion according to the above requirements. No other distribution election modifications hereunder shall be permitted.

(e)Notwithstanding the preceding provisions of this Section 6.02, if at any time the Participant’s vested interest in the Plan and any other non-qualified, defined contribution plan sponsored by his Employer and in which the Participant participates is less than the applicable dollar amount under Code Section 402(g)(1)(B), the Committee shall distribute such interest to the Participant in one lump sum, provided that the following requirements are satisfied:

(1)The payment must accompany the termination of the Participant’s entire interest in both the Plan and all similar plans or arrangements that would be aggregated under Treasury Regulation Section 1.409A-1(c); and

(2)No election must have been provided to the Participant with respect to the receipt of the payment.

(f)Prior Plan Elections. Notwithstanding the preceding provisions of this Section 6.02 and with respect to an Employee who was a Participant in the Plan in 1999, such Participant’s election with respect to the form of payment made pursuant to the provisions of the Plan in effect at that time shall remain in effect unless modified by the Participant in the manner described in paragraphs (a) or (d) of this Section 6.02.

6.03 Vesting of Benefits

(a)Compensation Reduction Contribution Account. A Participant is 100% vested in his Compensation Reduction Contribution Account at all times.

(b)Death or Disability. If a Participant’s Severance from Service is attributable to his death or Disability, he shall be entitled to the entire amount then credited to his Accounts.

(c)Termination of Employment For Reasons Other than Death or Disability.

(1)Additional Matching Contribution Account. If a Participant’s Severance from Service is not attributable to his death or Disability and he has an Additional Matching Contribution Account to his credit, he shall be entitled to amounts then 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, the Committee may, in its sole discretion, deem the Participant to be entitled to the entire amount then credited to his Additional Matching Contribution Account; provided, further, that upon the occurrence of a Change in Control, the Participant shall be entitled to the entire amount then credited to his Additional Matching Contribution Account.

(2)Other Accounts. If a Participant’s Severance from Service is not attributable to his death or Disability, he shall be entitled to a “vested percentage” of the amounts then credited to his Matching Contribution Account and Discretionary Contribution Account, if any, based on his years of Service as follows:

; provided, however, that if the Participant terminates employment by reason of Retirement, the Committee may, in its discretion, authorize up to full vesting of the entire amount then credited to such Accounts; provided, further, that upon the occurrence of a Change in Control, the Participant shall under all circumstances be entitled to the entire amount then credited to such Accounts. Notwithstanding the preceding provisions of this subparagraph (2), 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 Severance from Service is attributable to Retirement, 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 Severance from Service shall include any amounts to be credited pursuant to Section 4.01 hereof for the Year of Severance from Service but not yet allocated.

6.04 Death

If a Participant dies while in the service of an Employer, or after Severance from Service 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 Unforeseeable Emergency 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 preceding provisions of this Article VI, except as set forth in this Section 6.05. A distribution may be made to or on behalf of a Participant prior to his or her Severance from Service to the extent that the Participant demonstrates, to the satisfaction of the Committee, that he or she has encountered an Unforeseeable Emergency. The amount distributed to a Participant on account of an Unforeseeable Emergency may not exceed the amount necessary to satisfy such Emergency, plus amounts necessary to pay taxes reasonably anticipated as a result of the distribution, after taking into account the extent to which such hardship is or may be relieved through reimbursement or compensation by insurance or otherwise or by liquidation of the Participant’s assets (to the extent the liquidation of such assets would not itself cause severe financial hardship).

A Participant’s Compensation Reduction Agreement shall be terminated as soon as administratively feasible following the Participant’s receipt of a distribution due to Unforeseeable Emergency.

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 shall be effective only when filed with the Committee during the Participant’s lifetime. Each Beneficiary designation filed with the Committee shall 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 mariner 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:

(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.

7.01 No Trust Required

The adoption of this Plan and the segregation 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.

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.”

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 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, including the Administrator. 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 and the Administrator (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 on 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 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.

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 documents relevant to the benefit claim 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 on 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. To the extent possible, such payment will be made in a manner permitted under Section 409A of the Code and any guidance issued thereunder so as to comply with such Code Section.

9.09 Claims Procedure/Arbitration

Claims under this Plan shall be settled as provided under Exhibit A hereto.

10.01 Amendment

The Board of Directors of the Company, in its sole and unfettered discretion, may amend the Plan at any time, provided such amendment does not contravene the provisions of Section 409A of the Code and related guidance issued thereunder and Section 10.03 hereof.

10.02 Freeze/Termination

The Board of Directors of Company may freeze the Plan, in its sole and unfettered discretion, at any time, as to eligibility or future contributions; provided, however, that distributions pursuant to the Plan

shall not thereby be accelerated but payment shall be made at the time and in the manner specified under Article VI hereof. The Plan will remain in place, as frozen, until all amounts are distributed as required pursuant to the Plan terms.

The Board of Directors of Company may terminate the Plan, in its sole and unfettered discretion, at any time once amounts have been distributed as provided in the preceding paragraph; provided,, however, that if the Plan and all similar plans sponsored by the Company that are required to be aggregated with the Plan under Regulation Section 1.409A-1(c)(2) are terminated within the thirty (30) days preceding or the twelve (12) months following a Change in Control, payment of all amounts deferred under this Plan and such other plans shall be made in the form of a lump sum, which shall be paid no later than twelve (12) months following the date on which the Plan termination occurs.

10.03 Rights of Participants

No amendment, suspension, or termination of the Plan shall deprive a Participant of the vested amounts allocated to his or her Accounts as of such date. No amendment, suspension, or termination shall be retroactive in effect to the prejudice of any Participant, except to the extent necessary to comply with any provision of federal or applicable state laws or except to the extent necessary to prevent detriment to the Company or any of its Affiliates, or the current taxation of Participants under Code Section 409A and any guidance issued thereunder, as so determined by the Board in its sole and unfettered discretion. The foregoing notwithstanding, in the event it is determined by the Board, in its sole and unfettered discretion, that any provision in this Plan results in a violation of the requirements of Code Section 409A, any Regulations or guidance issued thereunder, or any other applicable law or Regulation, the Board, and any authorized officer so appointed by the Board, shall have the power unilaterally to modify or eliminate any such provision.

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.

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 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 Participant terminates employment with the Company or other Participating Employer 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 separated 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 Severance from Service, 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.

11.03 Compliance with Code Section 409A With Regard Article XI

If any provision of this Article XI is determined to violate Section 409A of the Code, such provision shall have no force or effect.

IN TESTIMONY WHEREOF, TRINITY INDUSTRIES, INC. has caused this instrument to be executed in its name and on its behalf, by the officer thereunto duly authorized, this 21st day of December 2020, effective as of January 1, 2021 or as otherwise provided herein.

(a) Claim Review Procedure (General). If a Participant, Beneficiary or alternate payee or his authorized representative asserts a right to a benefit under the Plan which has not been received or submits a request to enforce or clarify rights, including rights to future Plan benefits, or any request that relates to the Plan, such claimant must file a written claim with the Administrator in accordance with such procedures or on such forms as the Administrator may establish.

The Administrator shall render its decision on the claim within 90 days (45 days for a disability claim) after its receipt of the claim. If the Administrator determines that special circumstances require an extension of time for processing the claim, the initial 90-day period (45-day period for a disability claim) may be extended for up to 90 additional days (30 additional days for a disability claim). The Administrator shall give the claimant written notice of the extension prior to the expiration of the initial 90-day period (45-day period for a disability claim), and such notice shall set forth the circumstances requiring the extension of time and the date by which the Administrator expects to render a decision. In the case of a disability claim, if a decision still cannot be made within the initial 30-day extension period due to circumstances outside the Administrator’s control, the Administrator may extend the time period for responding to the claim by an additional 30 days, provided that the Administrator notifies the claimant in writing of such additional extension prior to the expiration of the original 30-day extension period.

If the Administrator extends the deadline for responding to a disability claim, the notice of such extension must also specifically explain the standards that determine whether a claimant is entitled to a benefit, the unresolved issues that prevent a decision on the disability claim, and the additional information needed to resolve those issues. If the deadline is extended because the claimant did not provide all of the necessary information to make a decision on the claim, the claimant will be given at least 45 days to provide the information and the deadline for making the benefit decision on the claim will be extended by the length of time that passes between the date the claimant is notified that more information is needed and the date that the claimant responds to the request for more information.

If the Administrator wholly or partially denies the claim, the Administrator shall provide written notice to the claimant within the time limitations of the immediately preceding paragraph. Such notice shall set forth, in a manner calculated to be understood by the claimant:

(1) the specific reason or reasons for the denial;

(2) the specific provisions of the Plan upon which the denial is based;

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

(4) a description of the Plan’s claims review procedures, and the time limitations applicable to such procedures; and

(5) a statement of the claimant’s right to bring suit under Section 502(a) of ERISA following an adverse benefit determination on appeal.

(b) Appeal Review Procedure. If a claim is denied in whole or in part, to request review of the denial, the claimant must file a written appeal of the denial, in accordance with such procedures as the Administrator may establish, which sets forth the claimant’s position and any documents, records or other information relating to the claim for benefits. Any such appeal must be filed within 60 days (180 days for a disability claim) of the claimant’s receipt of written notification of the denial of the claim. In connection with such an appeal, upon request and free of charge, the claimant shall be provided reasonable access to, and copies of, all documents, records and other information relevant to the claimant’s claim for benefits. If the claimant fails to file an appeal within such 60-day period (180-day period for a disability claim), then the claimant shall have no further right to appeal.

The Administrator’s review of an appeal shall take into account all comments, documents, records, and other information submitted by the claimant relating to the claim, without regard to whether such information was submitted or considered in the initial claim determination. The Administrator shall render its decision on the appeal not later than 60 days (45 days for a disability claim) after the receipt by

the Administrator of the appeal. If special circumstances apply, the 60-day period (45-day period for a disability claim) may be extended by an additional 60 days (45 days for a disability claim), provided that written notice of the extension is provided to the claimant during the initial 60-day period (45-day period for a disability claim) and such notice indicates the special circumstances requiring an extension of time and the date by which the Administrator expects to render its decision on the claim on appeal.

If the Administrator wholly or partially denies the claim on appeal, the Administrator shall provide written notice to the claimant within the time limitations of the immediately preceding paragraph. Such notice shall set forth, in a manner calculated to be understood by the claimant:

(1) the specific reason or reasons for denial;

(2) the specific references to the Plan provisions on which the decision was based;

(3) a statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of, all documents, records and other information relevant to the claimant’s claim for benefits; and

(4) a statement of the claimant’s right to bring suit under Section 502(a) of ERISA.

(c) Special Rules for Disability Claims. The following special rules apply to disability claims:

(1) Disability Claim Review Procedure. When the Administrator reviews a disability claim, the Administrator must meet the requirements set forth under Exhibit A(a) above. In addition, the requirements described in this Exhibit A(c)(1) shall also apply. If the Administrator wholly or partially denies a disability claim, the written notice of such denial must be provided in a culturally and linguistically appropriate manner, and shall set forth:

(A) the information described in Exhibit A(a)(1) through Exhibit A(a)(5);

(B) a discussion of the decision, including an explanation of the basis for disagreeing with or not following: (1) the views presented to the Administrator by health care professionals treating the claimant and vocational professionals who evaluated the claimant, (2) the views of medical or vocational experts obtained by the Administrator, without regard to whether the advice was relied upon in making the benefit determination, and (3) a disability determination made by the Social Security Administration;

(C) if the adverse benefit determination was based on a medical necessity or experimental treatment or similar exclusion or limit, either an explanation of the scientific or clinical judgment for the denial, applying the terms of the Plan to the claimant’s circumstances, or a statement that such an explanation will be provided free of charge upon request;

(D) the internal rules, guidelines, protocols, standards or other similar criteria relied upon in denying the claim, or a statement that such rules, guidelines, protocols, standards or other similar criteria do not exist; and

(E) a statement of the claimant’s right to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claimant’s claim for benefits.

(2) Disability Appeal Review Procedure. When the Administrator reviews a disability claim appeal, the Administrator must meet the requirements set forth under Exhibit A(b) above. In addition, the requirements described in this Exhibit A(c)(2) shall also apply.

For purposes of the Administrator’s review of a disability claim appeal, the review will not give deference to the claim denial and will not be made by the person who made the original claim denial, or a subordinate of that person. In deciding an appeal of any disability claim denial that is based in any way on a medical judgment, the Administrator must get advice from a health care professional who has training and experience in the area of medicine. Upon request, the claimant will be provided the names of any medical or vocational experts who were consulted in connection with the disability claim denial, even if the advice was not relied upon in making the denial. The health care professional consulted by the Administrator cannot be a person who was consulted by the Administrator in connection with the claim denial (or a subordinate of the person who was consulted in the original claim).

Before the Administrator issues an adverse benefit determination on review on a disability claim appeal, the Administrator must disclose to the claimant, free of charge, any new or additional evidence considered, relied upon, or generated by, or at the direction of, the Administrator in connection with the disability claim, and any new or additional rationale upon which such adverse benefit determination may be based. This information must be provided as soon as possible and sufficiently in advance of the date on which written notice of the Administrator’s determination on review is required to be provided under Exhibit A(b) so as to give the claimant a reasonable opportunity to respond prior to that date.

If the Administrator wholly or partially denies a disability claim on appeal, the written notice of such denial must be provided in a culturally and linguistically appropriate manner, and shall set forth:

(A) the information described in Exhibit A(b)(1) through Exhibit A(b)(4);

(B) the information described in Exhibit A(c)(1)(B) through (c)(1)(E); and

(C) any applicable contractual limitations period that applies to the claimant’s right to bring suit under Section 502(a) of ERISA, including the calendar date on which the contractual limitations period expires.

(d) Arbitration Requirements. 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.

(e) Exhaustion of Claims Procedures. A claim or action (i) to recover benefits allegedly due under the Plan or by reason of any law; (ii) to enforce rights under the Plan; (iii) to clarify rights to future benefits under the Plan; or (iv) that relates to the Plan and seeks a remedy, ruling or judgment of any kind against the Plan or a Plan fiduciary or party in interest (collectively, a “Judicial Claim”), may not be commenced in any court or forum until after the claimant has exhausted the Plan’s claims and appeals process (an “Administrative Claim”). A claimant must raise all arguments and produce all evidence that the claimant believes supports the claim or action in the Administrative Claim and shall be deemed to have waived every argument and the right to produce any evidence not submitted as part of the Administrative Claim.

Any Judicial Claim must be commenced in the appropriate court or forum no later than 24 months from the earliest of (i) the date the first benefit payment was made or allegedly due; (ii) the date the Administrator or its delegate first denied the claimant’s request; or (iii) the first date the claimant knew or should have known the principal facts on which such claim or action is based; provided, however, that, if the claimant commences an Administrative Claim before the expiration of such 24-month period, the period for commencing a Judicial Claim shall expire on the later of the end of the 24-month period and the date that is 3 months after the final denial of the claimant’s Administrative Claim, such that the claimant has exhausted the Plan’s claims and appeals procedures. Any claim or action that is commenced, filed or raised, whether a Judicial Claim or an Administrative Claim, after expiration of such 24-month limitations period (or, if applicable, expiration of the 3-month limitations period following exhaustion of the Plan’s claims and appeals procedures) shall be time-barred.

Filing or commencing a Judicial Claim before the claimant exhausts the Administrative Claim requirements shall not toll the 24-month limitations period (or, if applicable, the 3-month limitations period). If a claimant fails to file a claim or request for review in the manner specified herein, such claim or request shall be a waiver, and the claimant will be barred from reasserting the claim. Similarly, failure to follow the Plan’s prescribed claims and appeals process in a timely manner shall also cause the

claimant to lose the right to bring legal action against the Plan regarding an adverse benefit determination.

(f) Satisfaction of Claims. Any payment to a Participant or Beneficiary, or to his legal representative or heirs at law, all in accordance with the provisions of the Plan, shall to the extent thereof be in full satisfaction of all claims hereunder against the Trustee, the Administrator, and the Participating Companies, any of whom may require such Participant, Beneficiary, legal representative or heirs at law, as a condition to such payment, to execute a receipt and release therefor in such form as shall be determined by the Trustee, the Administrator or the Participating Companies, as the case may be. If receipt and release shall be required but execution by such Participant, Beneficiary, legal representative or heirs at law shall not be accomplished so that the terms of Section 6.02 (dealing with the timing of distributions) may be fulfilled, such benefits may be distributed or paid into any appropriate court or to such other place as such court shall direct, for disposition in accordance with the order of such court, and such distribution shall be deemed to comply with the requirements of Section 6.02.

Section 5.02(a) Participant Election. A Participant shall not be permitted to elect to invest any portion of his/her Account in Arcosa Stock Units after the Date of Divestiture and shall only hold Arcosa Stock Units herein, subject to divestiture requirements.

Section 5.04(a) General. For any Participant with an Account in this Plan on the Date of Divestiture, any Stock Unit in which such Participant’s prior Account balance was deemed invested shall continue to be invested in a specified number of Arcosa Stock Units as determined under the appropriate formula relating to the Spin Transaction.

Section 5.04(b). Investment in Stock Units.

(2) For purposes of calculating the number of Arcosa Stock Units credited or deemed credited to a Participant’s Account pursuant to Exhibit B Section 5.04(a) above on the Date of Divestiture, the Participant received a number of Arcosa Stock Units based on the number of Trinity Stock Units held by such Participant on the Date of Divestiture and as determined using such distribution ratio that is consistent with how all Trinity shareholders were treated in the Spin Transaction with such ratio declared by the Board of Directors prior to the Date of Divestiture. To the extent a Participant, has any investment of his Account in Arcosa Stock Units, he may, after the Date of Divestiture, elect, at any time and from time to time, to change such investment election and make alternative investments in substitution therefore. The following limitations apply to a Participant’s right to direct that his Account be invested in Arcosa Stock Units:

(i) A Participant may not make an election to allocate any future contributions to investment in Arcosa Stock Units.

(ii) A Participant may not take any action with respect to the investment of the Account that would result in an increase in the portion of the Account so invested in Arcosa Stock Units and

(iii) In the event of any dilution or other adjustment, any Arcosa Stock Units allocated to the Account of such Participant (or Former Participant or Beneficiary) shall continue to be adjusted as provided under paragraph (e) of Section 5.04 of the Plan.

(3) Participants will have until December 31, 2020 to evaluate the Plan’s fund line up and select where assets currently invested in Arcosa Stock Units should be deemed to be invested. If after December 31, 2020, any Arcosa Stock Units remain as a deemed investment in a Participant’s Account, such Arcosa Stock Units will be liquidated and the proceeds deemed to be invested in an appropriate investment alternative as selected by the Committee.
