          (a)      Trinity
                General Rule.  Except as provided in Section 3.04(c), Trinity shall prepare any Tax Return which it has the obligation and right to prepare and
              file, or cause to be prepared and filed, under Section 3.01, in accordance with reasonable Tax accounting practices selected by Trinity.

           

          (b)      Arcosa
                General Rule.  Except as provided in Section 3.04(c), with respect to any Tax Return that Arcosa has the obligation and right to prepare and
              file, or cause to be prepared and filed, under Section 3.02, such Tax Return shall be prepared in accordance with past practices, accounting methods,
              elections or conventions ("Past Practices") used with respect to the Tax Returns in question (unless there is no reasonable basis for the use
              of such Past Practices), and to the extent any items are not covered by Past Practices (or in the event that there is no reasonable basis for the use of such Past Practices), in accordance with reasonable Tax accounting practices selected by
              Arcosa.

           

          (c)      Reporting

                of Separation Transactions.  The Tax treatment of the Separation Transactions reported on any Tax Return shall be consistent with the treatment thereof in the Ruling Requests, the Tax Opinions and the Rulings, taking into account the
              jurisdiction in which such Tax Returns are filed, unless there is no reasonable basis for such Tax treatment.  Such treatment reported on any Tax Return for which Arcosa is the Responsible Company shall be consistent with that on any Tax
              Return filed or to be filed by Trinity or any member of the Trinity Group or caused or to be caused to be filed by Trinity, unless there is no reasonable basis for such Tax treatment.  In the event that a Company shall determine that there is
              no reasonable basis for the Tax treatment described in either of the preceding two sentences, such Company shall notify the other Company at least 20 Business Days prior to filing the relevant Tax Return and the Companies shall attempt in
              good faith to agree on the manner in which the relevant portion of the Separation Transactions shall be reported.

           

          Section 3.05     Consolidated or Combined Tax Returns.  Arcosa will elect and join, and will cause its respective Affiliates to elect and join, in filing any Joint Returns that Trinity determines are
              required to be filed or that Trinity elects to file pursuant to Section 3.01(a) that Arcosa is eligible to file under applicable Tax Law.

           

          Section 3.06     Right to Review Tax Returns.

           

          (a)      General.  The Responsible Company with respect to any material Tax Return shall make the portion of such Tax Return and related workpapers which are relevant to the determination of the other Company's rights or
              obligations under this Agreement available for review by the other Company, if requested, to the extent (i) such Tax Return relates to Taxes for which the requesting Company would reasonably be expected to be liable, (ii) the requesting
              Company would reasonably be expected to be liable in whole or in part for any additional Taxes owing as a result of adjustments to the amount of Taxes reported on such Tax Return, (iii) such Tax Return relates to Taxes for which the
              requesting Company would reasonably be expected to have a claim for Tax Benefits under this Agreement, or (iv) the requesting Company reasonably determines that it must inspect such Tax Return to confirm compliance with the terms of this
              Agreement.  The Responsible Company shall (i) use its reasonable best efforts to make such portion of such Tax Return available for review as required under this paragraph sufficiently in advance of the due date for filing of such Tax Return
              to provide the requesting Company with a meaningful opportunity to analyze and comment on such Tax Return and (ii) use reasonable efforts to have such Tax Return modified before filing, taking into account the person responsible for payment
              of the Tax (if any) reported on such Tax Return and whether the amount of Tax liability allocable to the requesting Company with respect to such Tax Return is material.  The Companies shall attempt in good faith to resolve any issues arising
              out of the review of such Tax Return.

           

          
            15

            
              

          

          (b)      Material Tax Returns.  For purposes of Section 3.06(a), a Tax Return is "material" if it could reasonably be expected to
              reflect (A) Tax liability equal to or in excess of $3 million, (B) a credit or credits equal to or in excess of $3 million or (C) a loss or losses equal to or in excess of $12 million, in each case with respect to the requesting Company.

           

          Section 3.07      Arcosa Carrybacks and Claims for Refund.  Arcosa hereby agrees that, unless Trinity consents in writing, (i) no Adjustment Request with respect to any Tax Return for a
              Pre-Distribution Period or Straddle Period shall be filed, and (ii) any available elections to waive the right to claim in any Pre-Distribution Period with respect to any Tax Return any Arcosa Carryback arising in a Post-Distribution Period
              shall be made, and no affirmative election shall be made to claim any such Arcosa Carryback.

           

          Section 3.08      Apportionment of Tax Attributes.  Trinity shall use its best efforts, by December 31 of the year following the year of the Distribution, to advise Arcosa in writing of the preliminary
              amount, if any, of any Tax Attributes, which Trinity reasonably determines shall be allocated or apportioned to the Arcosa Group under applicable law.  Arcosa shall have 60 Business Days to review and provide to Trinity written comments on
              such allocation and apportionment after receipt thereof from Trinity.  The Tax departments of Trinity and Arcosa shall negotiate in good faith to resolve any disagreements in respect of the allocation and apportionment within 30 Business Days
              after Trinity's receipt of any such written comments from Arcosa.  If any such disagreements cannot be resolved within such 30 Business Day period, then such disagreements shall be resolved in accordance with the provisions of Section 13.02 through Section 13.04.  If Arcosa does not submit written comments to Trinity within Arcosa's 60
              Business Day review and comment period described above, the allocation and apportionment of Tax Attributes as determined by Trinity and delivered to Arcosa pursuant to the first sentence of this Section 3.08 shall be deemed final, subject to final adjustments upon the filing of the final Trinity Federal Consolidated Income Tax Returns that include the Arcosa Group, and Arcosa agrees that
              it shall not dispute such allocation and apportionment.  For the avoidance of doubt, Trinity makes no representation or warranty as to the accuracy or completeness of any such determination.  Trinity and all members of the Trinity Group, and
              Arcosa and all members of the Arcosa Group, shall prepare all Tax Returns in accordance with the final determination of the allocation and apportionment under this Section

                  3.08 (including, if applicable, under Section 13), absent a Final Determination to the contrary in respect of the applicable Tax
              Attribute.  Notwithstanding anything to the contrary contained herein, except in the case of payments for which Trinity is responsible pursuant to Section 5.02,
              Trinity shall bear no liability to Arcosa for determinations made by Trinity pursuant to this Section 3.08 if any such determination shall be found or
              asserted to be inaccurate.

            Section 4.        Tax Payments.

          

           

          
          Section 4.01     Payment of Taxes With Respect to Certain Joint Returns.  In the case of any Joint Return:

           

          (a)      Computation and Payment of Tax Due.  At least five Business Days prior to any Payment Date for any such Tax Return, the Responsible Company shall compute the amount of Tax required to be paid to the applicable Tax
              Authority (taking into account the requirements of Section 3.04 relating to consistent accounting practices, as applicable) with respect to such Tax
              Return on such Payment Date.  The Responsible Company shall pay such amount to such Tax Authority on or before such Payment Date (and provide notice and proof of payment to the other Company).

           

          (b)      Computation and Payment of Liability With Respect To Tax Due.  Within 20 Business Days following the earlier of (i) the due date (including extensions) for filing any such Tax Return (excluding any Tax Return with
              respect to payment of estimated Taxes or Taxes due with a request for extension of time to file) or (ii) the date on which such Tax Return is filed, if Trinity is the Responsible Company, then Arcosa shall pay to Trinity the amount allocable
              to the Arcosa Group under the provisions of Section 2, and if Arcosa is the Responsible Company, then Trinity shall pay to Arcosa the amount allocable to
              the Trinity Group under the provisions of Section 2, in each case, plus interest computed at the Prime Rate on the amount of the payment based on the
              number of days from 10 Business Days after the earlier of (i) the due date of the Tax Return (including extensions) or (ii) the date on which such Tax Return is filed, to the date of payment.

           

          (c)      Adjustments Resulting in Underpayments.  In the case of any adjustment pursuant to a Final Determination with respect to any such Tax Return, the Responsible Company shall pay to the applicable Tax Authority when
              due any additional Tax due with respect to such Return required to be paid as a result of such adjustment pursuant to a Final Determination.  The Responsible Company shall compute the amount attributable to the Arcosa Group in accordance with
              Section 2 and Arcosa shall pay to Trinity any amount due Trinity (or Trinity shall pay Arcosa any amount due Arcosa) under Section 2 within 20 Business Days from the later of (i) the date the additional Tax was paid by the Responsible Company or (ii) the date of receipt of a written notice and demand from
              the Responsible Company for payment of the amount due, accompanied by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particulars relating thereto.  Any payments required under this Section 4.01(c) shall include interest computed at the Prime Rate based on the number of days from 10 Business Days after the later of (i) the date the
              additional Tax was paid by the Responsible Company or (ii) the date of receipt of a written notice and demand from the Responsible Company, to the date of the payment under this Section 4.01(c).

           

          Section 4.02     Payment of Separate Company Taxes.  Each Company shall pay, or shall cause to be paid, to the applicable Tax Authority when due all Taxes owed by such Company or a member of such
              Company's Group with respect to a Separate Return.

           

          
            17

            
              

          

          
            Section 4.03     Indemnification Payments.

          

           

          
          (a)      If any Company (the "Payor") is required under applicable Tax Law to pay to a Tax Authority a Tax that another Company (the "Required Party") is liable for under this Agreement, the Required Party shall reimburse the Payor within 20 Business Days of delivery by the Payor to the Required Party of an invoice for the amount
              due, accompanied by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particulars relating thereto.  The reimbursement shall include interest on the Tax payment computed at the Prime Rate
              based on the number of days from 10 Business Days after the date of delivery by the Payor to the Required Party of such invoice to the date of reimbursement under this Section

                  4.03.

           

          (b)      All indemnification payments under this Agreement shall be
              made by Trinity directly to Arcosa and by Arcosa directly to Trinity; provided, however, that if the Companies mutually agree with respect to
              any such indemnification payment, any member of the Trinity Group, on the one hand, may make such indemnification payment to any member of the Arcosa Group, on the other hand, and vice versa.  All indemnification payments shall be treated in
              the manner described in Section 12.01.

           

          Section 5.        Tax Refunds and Tax Benefits.

           

          Section 5.01     Tax Refunds.  Trinity shall be entitled to any refund (and any interest thereon received from the applicable Tax Authority) of Taxes for which Trinity is liable hereunder, Arcosa
              shall be entitled (subject to the limitations provided in Section 3.07) to any refund (and any interest thereon received from the applicable Tax
              Authority) of Taxes for which Arcosa is liable hereunder and a Company receiving a refund to which another Company is entitled hereunder shall pay over such refund to such other Company within 20 Business Days after such refund is received
              (together with interest computed at the Prime Rate based on the number of days from 10 Business Days after the date the refund was received to the date the refund was paid over).

           

          Section 5.02     Tax Benefits.   If pursuant to a Final Determination any adjustment (including a Transfer Pricing Adjustment) is made, or if a Transfer Pricing Adjustment otherwise occurs, which
              results in (i) a Tax for which the Trinity Group is liable hereunder (or a reduction in the Tax Attributes of the Trinity Group) and (ii) a corresponding Tax Benefit allowable to a member of the Arcosa Group, Arcosa shall make payment to
              Trinity within twenty (20) Business Days following such Final Determination, in an amount equal to the present value of such Tax Benefit (including any Tax Benefit made allowable as a result of the payment).  If pursuant to a Final
              Determination any adjustment (including a Transfer Pricing Adjustment) is made, or if a Transfer Pricing Adjustment otherwise occurs, which results in (i) a Tax for which the Arcosa Group is liable hereunder (or a reduction in the Tax
              Attributes of the Arcosa Group) and (ii) a corresponding Tax Benefit allowable to a member of the Trinity Group, Trinity shall make payment to Arcosa within twenty (20) Business Days following such Final Determination, in an amount equal to
              the present value of such Tax Benefit (including any Tax Benefit made allowable as a result of the payment).  The amount of a Tax Benefit shall be calculated by: (x) using the highest relevant marginal Tax rates in effect at the time of the
              Final Determination; (y) assuming the relevant benefitting Group member will be liable for such Taxes at such rate and has no Tax Attributes at the time of the Final Determination; and (z) assuming that any such Tax Benefit is used at the
              earliest date allowable by applicable law.  The present value referred to in this Section 5.02 shall be determined using a discount rate equal to the
              mid-term applicable federal rate in effect at the time of the Final Determination.

          Section 6.         Tax-Free Status.

           

          Section 6.01     Restrictions on Arcosa.

           

          (a)      Arcosa agrees that it will not take or fail to take, or
              permit any Arcosa Affiliate, as the case may be, to take or fail to take, any action where such action or failure to act would be inconsistent with or cause to be untrue any statement, information, covenant or representation in any
              Representation Letters, Tax Opinions or Rulings.  Arcosa agrees that it will not take or fail to take, or permit any Arcosa Affiliate, as the case may be, to take or fail to take, any action which adversely affects or could reasonably be
              expected to adversely affect (A) the Tax-Free Status of the Contribution and the Distribution, or (B) the qualification of any Separation Transaction under U.S. federal, state, local or non-U.S. Tax Law as wholly or partially tax-free or
              tax-deferred (including, but not limited to, those transactions described in any of the Tax Opinions or Rulings received with respect to such Separation Transaction).

           

          (b)      Arcosa agrees that, from the date hereof until the first
              Business Day after the two-year anniversary of the Distribution Date, it will (i) maintain its status as a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code, (ii) not engage in any transaction that
              would result in it ceasing to be a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code, and (iii) not engage in any transaction or permit an Arcosa Affiliate to engage in any transaction that would
              result in Arcosa ceasing to be a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) or such other applicable Tax Law, taking into account Section 355(b)(3) of the Code for purposes of clauses (i) through (iii)
              hereof.

           

          (c)      Arcosa agrees that, from the date hereof until the first
              Business Day after the two-year anniversary of the Distribution Date, it will not and will not permit any Arcosa Affiliate engaged in or treated as engaged in the Active Trade or Business to, and will not enter into any agreement to and will
              not permit any such Arcosa Affiliate to enter into any agreement to, (i) enter into any Proposed Acquisition Transaction or, to the extent Arcosa has the right to prohibit any Proposed Acquisition Transaction, permit any Proposed Acquisition
              Transaction to occur (whether by (a) redeeming rights under a shareholder rights plan, (b) finding a tender offer to be a "permitted offer" under any such plan or otherwise causing any such plan to be inapplicable or neutralized with respect
              to any Proposed Acquisition Transaction, (c) approving any Proposed Acquisition Transaction, whether for purposes of Section 203 of the DGCL or any similar corporate statute, any "fair price" or other provision of Arcosa's charter or bylaws,
              (d) amending its certificate of incorporation to declassify its board of directors or approving any such amendment, or otherwise), (ii) merge or consolidate with any other Person or liquidate or partially liquidate, (iii) in a single
              transaction or series of transactions sell or transfer (other than sales or transfers of inventory in the ordinary course of business) all or substantially all of the assets that were transferred to Arcosa pursuant to the Contribution or sell
              or transfer 25% or more of the gross assets of the Active Trade or Business or 25% or more of the consolidated gross assets of Arcosa and its Affiliates (such percentages to be measured based on fair market value as of the initial
              Distribution Date), (iv) redeem or otherwise repurchase (directly or through an Arcosa Affiliate) any Arcosa stock, or rights to acquire stock, except to the extent such repurchases satisfy Section 4.05(1)(b) of Revenue Procedure 96-30 (as in
              effect prior to the amendment of such Revenue Procedure by Revenue Procedure 2003-48), (v) amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or otherwise,
              affecting the voting rights of Arcosa Capital Stock (including, without limitation, through the conversion of one class of Arcosa Capital Stock into another class of Arcosa Capital Stock) or (vi) take any other action or actions (including
              any action or transaction that would be reasonably likely to be inconsistent with any representation made in the Representation Letters, Tax Opinions or Rulings) which in the aggregate (and taking into account any other transactions described
              in this subparagraph (c)) would be reasonably likely to have the effect of causing or permitting one or more persons (whether or not acting in concert) to acquire directly or indirectly stock representing a Fifty-Percent or Greater Interest
              in Arcosa or otherwise jeopardize the Tax-Free Status, unless prior to taking any such action set forth in the foregoing clauses (i) through
              (vi), (A) Arcosa shall have requested that Trinity obtain a Ruling from the IRS in accordance with Section 6.03(b) and (d) of this Agreement to the effect that such transaction will not affect the Tax-Free Status and Trinity shall have received such a Ruling in form and substance satisfactory to
              Trinity in its reasonable discretion, or (B) Arcosa shall provide Trinity with an Unqualified Tax Opinion in form and substance satisfactory to Trinity in its reasonable discretion (and in determining whether an opinion is satisfactory,
              Trinity may consider, among other factors, the appropriateness of any underlying assumptions and management's representations if used as a basis for the opinion and Trinity may determine that no opinion would be acceptable to Trinity) or (C)
              Trinity shall have expressly waived in writing the requirement to obtain such Ruling or Unqualified Tax Opinion.

           

          
            19

            
              

          

          (d)      Certain
                Issuances of Arcosa Capital Stock.  If Arcosa proposes to enter into any Section 6.01(d) Acquisition Transaction or, to the extent Arcosa has the right to prohibit any Section 6.01(d) Acquisition Transaction, proposes to permit any
              Section 6.01(d) Acquisition Transaction to occur, in each case, during the period from the date hereof until the first Business Day after the two-year anniversary of the Distribution Date, Arcosa shall provide Trinity, no later than ten
              Business Days before the signing of any written agreement with respect to the Section 6.01(d) Acquisition Transaction, with a written description of such transaction (including the type and amount of Arcosa Capital Stock to be issued in such
              transaction) and a certificate of the board of directors of Arcosa to the effect that the Section 6.01(d) Acquisition Transaction is not a Proposed Acquisition Transaction or any other transaction to which the requirements of Section 6.01(c) apply (a "Board Certificate").

           

          (e)      Gain
                Recognition Agreements.  Prior to any event that may result in recognition or recapture of income (including under any Gain Recognition Agreement) by Trinity or any member of the Trinity Group, Arcosa shall use (and shall cause the
              members of the Arcosa Group to use) all commercially reasonable efforts to eliminate such gain recognition or recapture of income or otherwise avoid or minimize the impact thereof to the Trinity Group, including by the execution of a Gain
              Recognition Agreement.

           

          Section 6.02     Restrictions on Trinity.  Trinity agrees that it will not take or fail to take, or permit any Trinity Affiliate, as the case may be, to take or fail to take, any action (i) where such
              action or failure to act would be inconsistent with or cause to be untrue any statement, information, covenant or representation in any Representation Letters, Tax Opinions or Rulings, or (ii) which adversely affects or could reasonably be
              expected to adversely affect (A) the Tax-Free Status of the Contribution and the Distribution, or (B) the qualification of any Separation Transaction under U.S. federal, state, local or non-U.S. Tax Law as tax free (including, but not limited
              to, those transactions described in any of the Tax Opinions or Rulings received with respect to such Separation Transaction) from so qualifying; provided,

                however, that this Section 6.02 shall not be construed as obligating Trinity to consummate the Distribution nor shall it be construed as
              preventing Trinity from terminating the Separation and Distribution Agreement pursuant to Section 10.10 thereof.  For avoidance of doubt, Arcosa's sole recourse for violations of this Section 6.02 shall be as set forth in Section 6.04(b).

           

          
            20

            
              

          

          Section 6.03     Procedures Regarding Opinions and Rulings.

           

          (a)      If Arcosa notifies Trinity that it desires to take one of
              the actions described in clauses (i) through (vi) of Section 6.01(c) (a "Notified Action"), Trinity and Arcosa shall reasonably cooperate to attempt to obtain the Ruling or Unqualified Tax Opinion referred to in Section

                  6.01(c), unless Trinity shall have waived the requirement to obtain such Ruling or Unqualified Tax Opinion; provided that
              seeking any Ruling shall require the consent of Trinity, such consent not to be unreasonably withheld.

           

          (b)      Rulings
                or Unqualified Tax Opinions at Arcosa's Request.  Trinity agrees that at the reasonable request of Arcosa pursuant to Section 6.01(c), Trinity
              shall cooperate with Arcosa and use reasonable efforts to seek to obtain, as expeditiously as possible, a Ruling from the IRS or an Unqualified Tax Opinion for the purpose of permitting Arcosa to take the Notified Action; provided that seeking any Ruling shall require the consent of Trinity, such consent not to be unreasonably withheld.  Further, in no event shall
              Trinity be required to file any Ruling Request under this Section 6.03(b) unless Arcosa represents that (A) it has read the Ruling Request, and (B) all
              information and representations, if any, relating to any member of the Arcosa Group, contained in the Ruling Request documents are (subject to any qualifications therein) true, correct and complete.  Arcosa shall reimburse Trinity for all
              third-party and other reasonable costs and expenses, including $200 per hour for expenses relating to the utilization of Trinity Group personnel, incurred by the Trinity Group in obtaining a Ruling or Unqualified Tax Opinion requested by
              Arcosa within ten Business Days after receiving an invoice from Trinity therefor; provided that Arcosa shall not be required to reimburse
              Trinity for such Trinity Group personnel expenses except to the extent that the aggregate amount of such personnel expenses exceeds $10,000 or the aggregate time spent by Trinity Group personnel in connection with such cooperation exceeds 50
              hours.

           

          (c)      Rulings or Unqualified Tax Opinions at Trinity's Request.  Trinity shall have the right to obtain a Ruling or an Unqualified Tax Opinion at any time in its sole and absolute discretion. 
              If Trinity determines to obtain a Ruling or an Unqualified Tax Opinion, Arcosa shall (and shall cause each Affiliate of Arcosa to) cooperate with Trinity and take any and all actions reasonably requested by Trinity in connection with
              obtaining the Ruling or Unqualified Tax Opinion (including, without limitation, by making any representation or covenant or providing any materials or information requested by the IRS or Tax Advisor; provided that Arcosa shall not be required
              to make (or cause any Affiliate of Arcosa to make) any representation or covenant that is inconsistent with historical facts or as to future matters or events over which it has no control).  Trinity shall reimburse Arcosa for all third-party
              and other reasonable costs and expenses, including $200 per hour for expenses relating to the utilization of Arcosa Group personnel, incurred by the Arcosa Group in connection with such cooperation within ten Business Days after receiving an
              invoice from Arcosa therefor; provided that Trinity shall not be required to reimburse Arcosa for such Arcosa Group personnel expenses except
              to the extent that the aggregate amount of such personnel expenses exceeds $10,000 or the aggregate time spent by Arcosa Group personnel in connection with such cooperation exceeds 50 hours.

           

          
            21

            
              

          

          (d)      Arcosa hereby agrees that Trinity shall have sole and
              exclusive control over the process of obtaining any Ruling, and that only Trinity shall apply for a Ruling.  In connection with obtaining a Ruling pursuant to Section

                  6.03(b), (A) Trinity shall keep Arcosa informed in a timely manner of all material actions taken or proposed to be taken by Trinity in connection therewith; (B) Trinity shall (1) reasonably in advance of the submission of any
              Ruling Request documents provide Arcosa with a draft copy thereof, (2) reasonably consider Arcosa's comments on such draft copy, and (3) provide Arcosa with a final copy; and (C) Trinity shall provide Arcosa with notice reasonably in advance
              of, and Arcosa shall have the right to attend, any formally scheduled meetings with the IRS (subject to the approval of the IRS) that relate to such Ruling.  Neither Arcosa nor any Arcosa Affiliate directly or indirectly controlled by Arcosa
              shall seek any guidance from the IRS or any other Tax Authority (whether written, verbal or otherwise) at any time concerning the Contribution or the Distribution (including the impact of any transaction on the Contribution or the
              Distribution).

           

          Section 6.04     Liability for Tax-Related Losses.

           

          (a)      Notwithstanding anything in this Agreement or the
              Separation and Distribution Agreement to the contrary (and in each case regardless of whether a Ruling, Unqualified Tax Opinion or waiver described in clause (A), (B) or (C) of Section 6.01(c) may have been provided), subject to Section 6.04(c), Arcosa shall be responsible for, and shall indemnify
              and hold harmless Trinity and its Affiliates and each of their respective officers, directors and employees from and against, one hundred percent (100%) of any Tax-Related Losses that are attributable to or result from any one or more of the
              following:  (A) the acquisition (other than pursuant to the Contribution or the Distribution) of all or a portion of Arcosa's stock and/or its or its subsidiaries' assets by any means whatsoever by any Person, (B) any negotiations,
              understandings, agreements or arrangements by Arcosa with respect to transactions or events (including, without limitation, stock issuances, pursuant to the exercise of stock options or otherwise, option grants, capital contributions or
              acquisitions, or a series of such transactions or events) that cause the Distribution to be treated as part of a plan pursuant to which one or more Persons acquire directly or indirectly stock of Arcosa representing a Fifty-Percent or Greater
              Interest therein, (C) any action or failure to act by Arcosa after the Distribution (including, without limitation, any amendment to Arcosa's certificate of incorporation (or other organizational documents), whether through a stockholder vote
              or otherwise) affecting the voting rights of Arcosa stock (including, without limitation, through the conversion of one class of Arcosa Capital Stock into another class of Arcosa Capital Stock), (D) any act or failure to act by Arcosa or any
              Arcosa Affiliate described in Section 6.01 (regardless whether such act or failure to act may be covered by a Ruling, Unqualified Tax Opinion or waiver
              described in clause (A), (B) or (C) of Section 6.01(c), or a Board Certificate described in Section 6.01(d)) or (E) any breach by Arcosa of its agreement and representation set forth in Section 6.01(a).

          (b)      Notwithstanding anything in this Agreement or the
              Separation and Distribution Agreement to the contrary, subject to Section 6.04(c), Trinity shall be responsible for, and shall indemnify and hold harmless
              Arcosa and its Affiliates and each of their respective officers, directors and employees from and against, one hundred percent (100%) of any Tax-Related Losses that are attributable to, or result from any one or more of the following:  (A)
              the acquisition (other than pursuant to the Contribution or the Distribution) of all or a portion of Trinity's stock and/or its assets by any means whatsoever by any Person, (B) any negotiations, agreements or arrangements by Trinity with
              respect to transactions or events (including, without limitation, stock issuances, pursuant to the exercise of stock options or otherwise, option grants, capital contributions or acquisitions, or a series of such transactions or events) that
              cause the Distribution to be treated as part of a plan pursuant to which one or more Persons acquire directly or indirectly stock of Trinity representing a Fifty-Percent or Greater Interest therein, or (C) any act or failure to act by Trinity
              or a member of the Trinity Group described in Section 6.02 or any breach by Trinity of its agreement and representation set forth in Section 6.02, limited, in each case, to Tax-Related Losses arising from Taxes of the Trinity Group for which an Arcosa Entity is found jointly, severally or
              secondarily liable pursuant to the provisions of Treasury Regulations Section 1.1502-6 (or similar provisions of state, local or foreign Tax Law).

           

          (c)          

          

          
             

            (i)           To the
                extent that any Tax-Related Loss is subject to indemnity under both Sections 6.04(a) and (b),
                responsibility for such Tax-Related Loss shall be shared by Trinity and Arcosa according to relative fault.

             

            (ii)          Notwithstanding

                anything in Section 6.04(b) or (c)(i) or any other provision of this Agreement or
                the Separation and Distribution Agreement to the contrary:

             

             

            (A)          with
                respect to (I) any Tax-Related Loss resulting from Section 355(e) of the Code (other than as a result of an acquisition of a Fifty-Percent or Greater Interest in Trinity) and (II) any other Tax-Related Loss resulting (for the absence of
                doubt, in whole or in part) from an acquisition after the Distribution of any stock or assets of Arcosa (or any Arcosa Affiliate) by any means whatsoever by any Person or any action or failure to act by Arcosa affecting the voting rights of
                Arcosa stock, Arcosa shall be responsible for, and shall indemnify and hold harmless Trinity and its Affiliates and each of their respective officers, directors and employees from and against, one hundred percent (100%) of such Tax-Related
                Loss; and

             

            (B)          for
                purposes of calculating the amount and timing of any Tax-Related Loss for which Arcosa is responsible under this Section 6.04, Tax-Related Losses shall be
                calculated by assuming that Trinity, the Trinity Affiliated Group and each member of the Trinity Group (I) pay Tax at the highest marginal corporate Tax rates in effect in each relevant taxable year and (II) have no Tax Attributes in any
                relevant taxable year.

          

           

          
            23

            
              

          

          
            
              
                (iii)         Notwithstanding

                    anything in Section 6.04(a) or (c)(i) or any other provision of this Agreement
                    or the Separation and Distribution Agreement to the contrary, with respect to (I) any Tax-Related Loss resulting from Section 355(e) of the Code (other than as a result of an acquisition of a Fifty-Percent or Greater Interest in Arcosa)
                    and (II) any other Tax-Related Loss resulting (for the absence of doubt, in whole or in part) from an acquisition after the Distribution of any stock or assets of Trinity (or any Trinity Affiliate) by any means whatsoever by any Person,
                    Trinity shall be responsible for, and shall indemnify and hold harmless Arcosa and its Affiliates and each of their respective officers, directors and employees from and against, one hundred percent (100%) of such Tax-Related Loss.

                 

            

          

           

          (d)      Arcosa shall pay Trinity the amount of any Tax-Related
              Losses for which Arcosa is responsible under this Section 6.04:  (A) in the case of Tax-Related Losses described in clause (i) of the definition of
              Tax-Related Losses no later than twenty Business Days prior to the date Trinity files, or causes to be filed, the applicable Tax Return for the year of the Contribution or Distribution, as applicable (the "Filing Date") (provided that if such Tax-Related Losses arise pursuant to a Final Determination described in clause (i), (ii) or (iii) of the definition of "Final Determination", then Arcosa shall pay Trinity no later than twenty Business Days after the date of such Final Determination with interest
              calculated at the Prime Rate plus two percent, compounded semiannually, from the date that is two Business Days prior to the Filing Date through the date of such Final Determination) and (B) in the case of Tax-Related Losses described in
              clause (ii) or (iii) of the definition of Tax-Related Losses, no later than twenty Business Days after the date Trinity pays such Tax-Related Losses.  Trinity shall pay Arcosa the amount of any Tax-Related Losses (described in clause (ii) or
              (iii) of the definition of Tax-Related Loss) for which Trinity is responsible under this Section 6.04 no later than twenty Business Days after the date
              Arcosa pays such Tax-Related Losses.

           

          (e)      To the extent that neither Trinity nor Arcosa would be
              responsible for a Tax-Related Loss pursuant to Section 6.04(a), Section
                  6.04(b) or Section 6.04(c), responsibility for such Tax-Related Loss shall be shared by Trinity and Arcosa in accordance with Trinity's and
              Arcosa's relative market capitalizations as of the Distribution Date (determined based upon the average trading prices of Trinity and Arcosa during the ten trading days beginning on the Distribution Date).

            Section 7.        Assistance and Cooperation.

             

            Section 7.01     Assistance and Cooperation.

          

           

            

          (a)      The Companies shall cooperate (and cause their respective
              Affiliates to cooperate) with each other and with each other's agents, including accounting firms and legal counsel, in connection with Tax matters relating to the Companies and their Affiliates including (i) preparation and filing of Tax
              Returns, (ii) determining the liability for and amount of any Taxes due (including estimated Taxes) or the right to and amount of any refund of Taxes, (iii) examinations of Tax Returns, and (iv) any administrative or judicial proceeding in
              respect of Taxes.  Such cooperation shall include making all information and documents in their possession relating to the other Company and its Affiliates available to such other Company as provided in Section 8.  Each of the Companies shall also make available to the other, as reasonably requested and available, personnel (including officers, directors, employees and agents of the
              Companies or their respective Affiliates) responsible for preparing, maintaining, and interpreting information and documents relevant to Taxes, and personnel reasonably required as witnesses or for purposes of providing information or
              documents in connection with any administrative or judicial proceedings relating to Taxes.  In the event that a member of the Trinity Group, on the one hand, or a member of the Arcosa Group, on the other hand, suffers a Tax detriment as a
              result of a Transfer Pricing Adjustment, the Companies shall cooperate pursuant to this Section 7 to seek any competent authority relief that may be
              available with respect to such Transfer Pricing Adjustment.  Arcosa shall cooperate with Trinity and take any and all actions reasonably requested by Trinity in connection with obtaining the Tax Opinions or the Rulings (including, without
              limitation, by making any new representation or covenant, confirming any previously made representation or covenant or providing any materials or information requested by any Tax Advisor or Tax Authority; provided that, Arcosa shall not be required to make or confirm any representation or covenant that is inconsistent with historical facts or as to future matters or events over which
              it has no control).  The requesting Company shall reimburse the other Company for all third-party and other reasonable costs and expenses, including $200 per hour for expenses relating to the utilization of the other Group's personnel,
              incurred by the cooperating Group in complying with this Section 7.01(a) within ten Business Days after receiving an invoice from the cooperating Company
              therefor; provided that neither Company shall be required to reimburse the other for such personnel expenses except to the extent that the
              aggregate amount of such cooperating Group personnel expenses exceeds $10,000 or the aggregate time spent by the cooperating Group personnel in connection with such cooperation exceeds 50 hours. The Transition Services Agreement, dated
            as of October 31, 2018, by and between Trinity and Arcosa, and the schedules thereto, shall govern the payment for inter-Group support and services in respect of Tax items expressly provided for therein, and the preceding sentence shall not apply with respect to such Tax items.

           

          (b)      Any information or documents provided under this Section 7 shall be kept confidential by the Company receiving the information or documents, except as may otherwise be necessary in connection with the filing
              of Tax Returns or in connection with any administrative or judicial proceedings relating to Taxes.  Notwithstanding any other provision of this Agreement or any other agreement, (i) neither Trinity nor any Trinity Affiliate shall be required
              to provide Arcosa or any Arcosa Affiliate or any other Person access to or copies of any information, documents or procedures (including the proceedings of any Tax Contest) other than information, documents or procedures that relate to
              Arcosa, the business or assets of Arcosa or any Arcosa Affiliate and (ii) in no event shall Trinity or any Trinity Affiliate be required to provide Arcosa, any Arcosa Affiliate or any other Person access to or copies of any information or
              documents if such action could reasonably be expected to result in the waiver of any Privilege.  In addition, in the event that Trinity determines that the provision of any information or documents to Arcosa or any Arcosa Affiliate could be
              commercially detrimental, violate any law or agreement or waive any Privilege, the Companies shall use reasonable best efforts to permit compliance with its obligations under this Section 7 in a manner that avoids any such harm or consequence.

           

          
            25

            
              

          

          Section 7.02     Income Tax Return Information.  Arcosa and Trinity acknowledge that time is of the essence in relation to any request for information, assistance or cooperation made by Trinity or
              Arcosa pursuant to Section 7.01 or this Section 7.02.  Arcosa and
              Trinity acknowledge that failure to conform to the reasonable deadlines set by Trinity or Arcosa could cause irreparable harm.  Each Company shall provide to the other Company information and documents relating to its Group required by the
              other Company to prepare Tax Returns, including, but not limited to, any pro forma returns required by the Responsible Company for purposes of preparing such Tax Returns.  Any information or documents the Responsible Company requires to
              prepare such Tax Returns shall be provided in such form as the Responsible Company reasonably requests and at or prior to the time reasonably specified by the Responsible Company so as to enable the Responsible Company to file such Tax
              Returns on a timely basis.

           

          Section 7.03     Reliance by Trinity.  If any member of the Arcosa Group supplies information to a member of the Trinity Group in connection with a Tax liability and an officer of a member of the
              Trinity Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the Trinity Group identifying the information being so relied
              upon, the chief financial officer of Arcosa (or any officer of Arcosa as designated by the chief financial officer of Arcosa) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the
              information so supplied is accurate and complete.

           

          Section 7.04     Reliance by Arcosa.  If any member of the Trinity Group supplies information to a member of the Arcosa Group in connection with a Tax liability and an officer of a member of the
              Arcosa Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the Arcosa Group identifying the information being so relied upon,
              the chief financial officer of Trinity (or any officer of Trinity as designated by the chief financial officer of Trinity) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the
              information so supplied is accurate and complete.

           

          Section 8.         Tax Records.

           

          Section 8.01     Retention of Tax Records.  Each Company shall preserve and keep all Tax Records exclusively relating to the assets and activities of its Group for Pre-Distribution Periods, and
              Trinity shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Distribution Tax Periods, for so long as the contents thereof may become material in the administration of any matter under the Code or other
              applicable Tax Law, but in any event until the later of (i) two years after the expiration of any applicable statutes of limitations, or (ii) ten years after the Distribution Date (such later date, the "Retention Date").  After the Retention Date, each Company may dispose of such Tax Records upon 60 Business Days' prior written notice to the other Company.  If, prior to
              the Retention Date, (a) a Company reasonably determines that any Tax Records which it would otherwise be required to preserve and keep under this Section 8
              are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Company agrees, then such first Company may dispose of such Tax Records upon 60 Business Days' prior notice to the other
              Company.  Any notice of an intent to dispose given pursuant to this Section 8.01 shall include a list of the Tax Records to be disposed of describing in
              reasonable detail each file, book, or other record accumulation being disposed.  The notified Company shall have the opportunity, at its cost and expense, to copy or remove, within such 60 Business Day period, all or any part of such Tax
              Records.  If, at any time prior to the Retention Date, Arcosa determines to decommission or otherwise discontinue any computer program or information technology system used to access or store any Tax Records, then Arcosa may decommission or
              discontinue such program or system upon 90 days' prior notice to Trinity and Trinity shall have the opportunity, at its cost and expense, to copy, within such 60 Business Day period, all or any part of the underlying data relating to the Tax
              Records accessed by or stored on such program or system.

           

          
            26

            
              

          

          Section 8.02     Access to Tax Records.  The Companies and their respective Affiliates shall make available to each other for inspection and copying during normal business hours upon reasonable notice
              all Tax Records (and, for the avoidance of doubt, any pertinent underlying data accessed or stored on any computer program or information technology system) in their possession and shall permit the other Company and its Affiliates, authorized
              agents and representatives and any representative of a Tax Authority or other Tax auditor direct access during normal business hours upon reasonable notice to any computer program or information technology system used to access or store any
              Tax Records, in each case to the extent reasonably required by the other Company in connection with the preparation of Tax Returns or financial accounting statements, audits, litigation, or the resolution of items under this Agreement.  The
              Company (and any of its Affiliates) seeking access to such Tax Records shall reimburse the other Company for all third-party and other reasonable costs and expenses, including $200 per hour for expenses relating to the utilization of the
              other Group's personnel, incurred by the cooperating Group in complying with this Section 8.02 within ten Business Days after receiving an invoice from
              the cooperating Company therefor; provided that neither Company shall be required to reimburse the other for such personnel expenses except
              to the extent that the aggregate amount of such cooperating Group personnel expenses exceeds $10,000 or the aggregate time spent by the cooperating Group personnel in connection with such cooperation exceeds 50 hours.

           

          Section 8.03     Preservation of Privilege.  No member of the Arcosa Group shall provide access to, copies of, or otherwise disclose to any Person any documentation relating to Taxes existing prior to
              the Distribution Date to which Privilege may reasonably be asserted without the prior written consent of Trinity, such consent not to be unreasonably withheld.

           

          Section 9.         Tax Contests.

           

          Section 9.01     Notice.  Each of the Companies shall provide prompt notice to the other Company of any written communication from a Tax Authority regarding any pending Tax audit, assessment or
              proceeding or other Tax Contest of which it becomes aware related to Taxes for Tax Periods for which it is indemnified by the other Company hereunder or for which it may be required to indemnify the other Company hereunder.  Such notice shall
              attach copies of the pertinent portion of any written communication from a Tax Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of
              any notice and other documents received from any Tax Authority in respect of any such matters.  If an indemnified Company has knowledge of an asserted Tax liability with respect to a matter for which it is to be indemnified hereunder and such
              Company fails to give the indemnifying Company prompt notice of such asserted Tax liability and the indemnifying Company is entitled under this Agreement to contest the asserted Tax liability, then (i) if the indemnifying Company is precluded
              from contesting the asserted Tax liability in any forum as a result of the failure to give prompt notice, the indemnifying Company shall have no obligation to indemnify the indemnified Company for any Taxes arising out of such asserted Tax
              liability, and (ii) if the indemnifying Company is not precluded from contesting the asserted Tax liability in any forum, but such failure to give prompt notice results in a material monetary detriment to the indemnifying Company, then any
              amount which the indemnifying Company is otherwise required to pay the indemnified Company pursuant to this Agreement shall be reduced by the amount of such detriment.

           

          
            27

            
              

          

          Section 9.02     Control of Tax Contests.

           

          (a)      Separate Returns.  In the case of any Tax Contest with respect to any Separate Return, the Company having liability for the Tax pursuant to Section

                  2 hereof shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Sections 9.02(c) and (d) below.

           

          (b)      Joint
                Return.  In the case of any Tax Contest with respect to any Joint Return, Trinity shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Sections 9.02(c) and (d) below.

           

          (c)      Settlement

                Rights.  The Controlling Party shall have the sole right to contest, litigate, compromise and settle any Tax Contest without obtaining the prior consent of the Non-Controlling Party.  Unless waived by the Companies in writing, in
              connection with any potential adjustment in a Tax Contest as a result of which adjustment the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this
              Agreement:  (i) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all actions taken or proposed to be taken by the Controlling Party with respect to such potential adjustment in such Tax Contest; (ii)
              the Controlling Party shall timely provide the Non-Controlling Party copies of any written materials relating to such potential adjustment in such Tax Contest received from any Tax Authority; (iii) the Controlling Party shall timely provide
              the Non-Controlling Party with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such potential adjustment in such Tax Contest; (iv) the Controlling Party shall consult with the
              Non-Controlling Party and offer the Non-Controlling Party a reasonable opportunity to comment before submitting any written materials prepared or furnished in connection with such potential adjustment in such Tax Contest; and (v) the
              Controlling Party shall defend such Tax Contest diligently and in good faith.  The failure of the Controlling Party to take any action specified in the preceding sentence with respect to the Non-Controlling Party shall not relieve the
              Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was actually harmed by such failure, and in no event shall such
              failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.  In the case of any Tax Contest described in Section 9.02(a) or (b),  "Controlling

                Party" means the Company entitled to control the Tax Contest under such Section and "Non-Controlling Party" means the other Company.

           

          (d)      Tax
                Contest Participation.  Unless waived by the Companies in writing, the Controlling Party shall provide the Non-Controlling Party with written notice reasonably in advance of, and the Non-Controlling Party shall have the right to
              attend, any formally scheduled meetings with Tax Authorities or hearings or proceedings before any judicial authorities in connection with any potential adjustment in a Tax Contest pursuant to which the Non-Controlling Party may reasonably be
              expected to become liable to make any indemnification payment to the Controlling Party under this Agreement.  The failure of the Controlling Party to provide any notice specified in this Section 9.02(d) to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent
              that the Non-Controlling Party was actually harmed by such failure, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.

          (e)      Power
                of Attorney.  Each member of the Arcosa Group shall execute and deliver to Trinity (or such member of the Trinity Group as Trinity shall designate) any power of attorney or other similar document reasonably requested by Trinity (or
              such designee) in connection with any Tax Contest (as to which Trinity is the Controlling Party) described in this Section 9.  Each member of the Trinity
              Group shall execute and deliver to Arcosa (or such member of the Arcosa Group as Arcosa shall designate) any power of attorney or other similar document requested by Arcosa (or such designee) in connection with any Tax Contest (as to which
              Arcosa is the Controlling Party) described in this Section 9.

           

          Section 10.      Effective Date.  This Agreement shall be effective as of the date hereof.

           

          Section 11.      Survival of Obligations.  The representations, warranties, covenants and agreements set forth in this Agreement shall be unconditional and absolute and shall remain in effect without
              limitation as to time.

           

          Section 12.      Treatment of Payments.

           

          Section 12.01   Treatment of Tax Indemnity Payments.  In the absence of any change in Tax treatment under the Code or except as otherwise required by other applicable Tax Law, any Tax indemnity
              payments made by a Company under this Agreement shall be reported for Tax purposes by the payor and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Distribution (but only to the extent
              the payment does not relate to a Tax allocated to the payor in accordance with Section 1552 of the Code or the regulations thereunder or Treasury Regulations Section 1.1502-33(d) (or under corresponding principles of other applicable Tax
              Laws)) or as payments of an assumed or retained liability.  Except to the extent provided in Section 12.02, any Tax indemnity payment made by a Company
              under this Agreement shall be increased as necessary so that after making all payments in respect to Taxes imposed on or attributable to such indemnity payment, the recipient Company receives an amount equal to the sum it would have received
              had no such Taxes been imposed.  For the avoidance of doubt, all payments made pursuant to this Agreement shall be between Trinity and Arcosa (and no other Group companies).

           

          Section 12.02    Interest Under This Agreement.  Anything herein to the contrary notwithstanding, to the extent one Company ("Indemnitor") makes a payment of interest to another Company ("Indemnitee") under this Agreement with respect to
              the period from the date that the Indemnitee made a payment of Tax to a Tax Authority to the date that the Indemnitor reimbursed the Indemnitee for such Tax payment, the interest payment shall be treated as interest expense to the Indemnitor
              (deductible to the extent provided by law) and as interest income by the Indemnitee (includible in income to the extent provided by law).  The amount of the payment shall not be adjusted to take into account any associated Tax Benefit to the
              Indemnitor or increase in Tax to the Indemnitee.

           

          
            29

            
              

          

          Section 13.      Disagreements.

           

          Section 13.01   Discussion.  The Companies mutually desire that friendly collaboration will continue between them.  Accordingly, they will try, and they will cause their respective Group members to
              try, to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement, including any amendments hereto.  In furtherance thereof, in the event of any dispute
              or disagreement between any member of the Trinity Group and any member of the Arcosa Group as to the interpretation of any provision of this Agreement or the performance of obligations hereunder (a "Dispute"), a Company's Tax department must provide written notice of such Dispute ("Dispute
                Notice").  Within thirty (30) days of receipt by a Company of a Dispute Notice, the receiving Company's Tax department shall submit to the other Company's Tax department a written response.  The Dispute Notice and the response shall
              each include a statement of the Company's position, a general summary of the arguments (including relevant facts and circumstances) supporting that position, the name and title of the Company's representatives who will represent the Company
              and any other person(s) in negotiation of the Dispute. The Tax departments of the Companies shall negotiate in good faith to resolve the Dispute.

           

          Section 13.02   Escalation.  If such good faith negotiations do not resolve the Dispute within forty-five (45) days from the time of receipt of the response to the Dispute Notice and the forty-five
              (45) day period is not extended by mutual written consent, then the Chief Financial  Officers of the Companies shall enter into negotiations for a reasonable period of time to settle  such Dispute; provided, however, that such reasonable
              period shall not, unless otherwise agreed by the Companies in writing, exceed thirty (30) days from the 45th day noted above, if and as  extended by mutual agreement of the Companies, as provided for in Section 8.1 of the  Separation and
              Distribution Agreement. If such good faith negotiations between the Chief Financial Officers do not resolve the Dispute within such period, then the Chief Executive Officers of the Companies shall enter into negotiations for a reasonable
              period of time to settle such Dispute; provided, however, that such reasonable period shall not, unless otherwise agreed by the Companies in writing, exceed thirty (30) days from the 30th day noted above, if and as extended by mutual
              agreement of the Companies, as provided for in Section 8.1 of the Separation and Distribution Agreement.  Except as expressly provided herein, Disputes hereunder shall not be subject to the dispute resolution procedures set forth in the
              Separation and Distribution Agreement.

           

          Section 13.03   Referral to Tax Advisor.  If the Companies are not able to resolve the Dispute through the escalation process referred to above, then the matter will be referred to a Tax Advisor
              acceptable to each of the Companies to act as an arbitrator in order to resolve the Dispute.  In the event that the Companies are unable to agree upon a Tax Advisor within 15 Business Days following the completion of the escalation process,
              the Companies shall each separately retain an independent, nationally recognized law or accounting firm (each, a "Preliminary Tax Advisor"),
              which Preliminary Tax Advisors shall jointly select a Tax Advisor on behalf of the Companies to act as an arbitrator in order to resolve the Dispute. The Tax Advisor may, in its discretion, obtain the services of any third-party appraiser,
              accounting firm or consultant that the Tax Advisor deems necessary to assist it in resolving such disagreement. The Tax Advisor shall furnish written notice to the Companies of its resolution of any such Dispute as soon as practical, but in
              any event no later than 30 Business Days after its acceptance of the matter for resolution. Any such resolution by the Tax Advisor will be final and binding on the Companies. Following receipt of the Tax Advisor's written notice to the
              Companies of its resolution of the Dispute, the Companies shall each take or cause to be taken any action necessary to implement such resolution of the Tax Advisor. Each Company shall pay its own fees and expenses (including the fees and
              expenses of its representatives) incurred in connection with the referral of the matter to the Tax Advisor (and the Preliminary Tax Advisors, if any). All fees and expenses of the Tax Advisor (and the Preliminary Tax Advisors, if any) in
              connection with such referral shall be shared equally by the Companies.

          Section 13.04   Injunctive Relief.  Nothing in this Section 13 will prevent either Company from seeking
              injunctive or other similar equitable relief if any delay resulting from the efforts to resolve the Dispute through the process set forth above could result in serious and irreparable injury to either Company. Notwithstanding anything to the
              contrary in this Agreement, Trinity and Arcosa are the only members of their respective Group entitled to commence a dispute resolution procedure under this Agreement, and each of Trinity and Arcosa will cause its respective Group members not
              to commence any dispute resolution procedure other than through such Company as provided in this Section 13.

           

          Section 14.      Late Payments.  Any amount owed by one Company to another Company under this Agreement which is not paid when due shall bear interest at the Prime Rate plus two percent, compounded
              semiannually, from the due date of the payment to the date paid.  To the extent interest required to be paid under this Section 14 duplicates interest
              required to be paid under any other provision of this Agreement, interest shall be computed at the higher of the interest rate provided under this Section 14
              or the interest rate provided under such other provision.

           

          Section 15.      Expenses.  Except as otherwise provided in this Agreement, each Company and its Affiliates shall bear their own expenses incurred in connection with preparation of Tax Returns, Tax
              Contests, and other matters related to Taxes under the provisions of this Agreement.

           

          Section 16.      General Provisions.

           

          Section 16.01    Addresses and Notices.  All notices, requests, claims, demands and other communications under this Agreement as between the Companies shall be in writing and shall be given or made

              courier service, by electronic e-mail with receipt confirmed (followed by delivery of an original via overnight courier service) or by registered or certified mail (postage prepaid, return receipt requested) to the respective Companies at the
              following addresses (or at such other address for a Company as shall be specified in a notice given in accordance with this Section 16.01).

          Section 16.03   Waiver.  The Companies may waive a provision of this Agreement only by a writing signed by the Company intended to be bound by the waiver.  A Company is not prevented from enforcing
              any right, remedy or condition in the Company's favor because of any failure or delay in exercising any right or remedy or in requiring satisfaction of any condition, except to the extent that the Company specifically waives the same in
              writing.  A written waiver given for one matter or occasion is effective only in that instance and only for the purpose stated.  A waiver once given is not to be construed as a waiver for any other matter or occasion.  Any enumeration of a
              Company's rights and remedies in this Agreement is not intended to be exclusive, and a Company's rights and remedies are intended to be cumulative to the extent permitted by law and include any rights and remedies authorized in law or in
              equity.

           

          Section 16.04   Severability.  If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future law, the remaining provisions of this Agreement will
              remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom.

           

          Section 16.05   Authority.  Each of the Companies represents to the other that (a) it has the corporate or other requisite power and authority to execute, deliver and perform this Agreement, (b) the
              execution, delivery and performance of this Agreement have been duly authorized by all necessary corporate or other action, (c) it has duly and validly executed and delivered this Agreement, and (d) this Agreement is a legal, valid and
              binding obligation, enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors' rights generally and general equity principles.

           

          Section 16.06   Further Action.  The Companies shall execute and deliver all documents, provide all information, and take or refrain from taking action as may be necessary or appropriate to achieve
              the purposes of this Agreement, including the execution and delivery to the other Company and its Affiliates and representatives of such powers of attorney or other authorizing documentation as is reasonably necessary or appropriate in
              connection with Tax Contests (or portions thereof) under the control of such other Company in accordance with Section 9.

          Section 16.07   Integration.  This Agreement contains the entire agreement between the Companies with respect to the subject matter hereof and supersedes all other agreements, whether or not written,
              in respect of any Tax between or among any member or members of the Trinity Group, on the one hand, and any member or members of the Arcosa Group, on the other hand.  All such other agreements shall be of no further effect between the
              Companies and any rights or obligations existing thereunder shall be fully and finally settled, calculated as of the date hereof.  In the event of any inconsistency between this Agreement and the Separation and Distribution Agreement or any
              of the Transfer Documents (as defined in the Separation and Distribution Agreement), or any other agreements relating to the transactions contemplated by the Separation and Distribution Agreement, with respect to the subject matter hereof,
              the provisions of this Agreement shall control.

           

          Section 16.08   Construction.  The language in all parts of this Agreement shall in all cases be construed according to its fair meaning and shall not be strictly construed for or against either
              Company.  The captions, titles and headings included in this Agreement are for convenience only, and do not affect this Agreement's construction or interpretation.  Unless otherwise indicated, all "Section" references in this Agreement are to

              has been fully compensated under any other provision of this Agreement or under any other agreement or action at law or equity.  Unless expressly required in this Agreement, a Company shall not be required to exhaust all remedies available
              under other agreements or at law or equity before recovering under the remedies provided in this Agreement.

           

          Section 16.10   Counterparts.  This Agreement may be executed in more than one counterparts, all of which shall be considered one and the same agreement, and, shall become effective when one or more
              such counterparts have been signed by each of the Companies and delivered to the other Company.  Execution of this Agreement or any other documents pursuant to this Agreement by facsimile or other electronic copy of a signature shall be
              deemed to be, and shall have the same effect as, executed by an original signature.

           

          Section 16.11   Governing Law.  This Agreement, and all actions, causes of action, or claims of any kind (whether at law, in equity, in contract, in tort, or otherwise) that may be based upon, arise
              out of, or relate to this Agreement, or the negotiation, execution, or performance of this Agreement (including any action, cause of action, or claim of any kind based upon, arising out of, or related to any representation or warranty made
              in, in connection with, or as an inducement to this Agreement) shall be governed by and construed in accordance with the law of the State of Delaware, irrespective of the choice of Laws principles of the State of Delaware, including without
              limitation Delaware laws relating to applicable statutes of limitations and burdens of proof and available remedies.

          Section 16.12   Jurisdiction.  Except as expressly contemplated by another provision of this Agreement, each of the Companies hereto agrees that the appropriate, exclusive and convenient forum for
              any disputes between any of the Companies hereto arising out of this Agreement or the transactions contemplated hereby shall be brought and determined in the Court of Chancery of the State of Delaware, provided, that if jurisdiction is not
              then available in the Court of Chancery of the State of Delaware, then any such legal action or proceeding may be brought in any federal court located in the State of Delaware or any other Delaware state court (the "Delaware Courts").  Each
              of the Companies further agrees that delivery of notice or document by United States registered mail to such Party's respective address set forth in Section 16.01
              shall be effective as to the contents of such notice or document, provided that service of process or summons for any action, suit or proceeding in the Delaware Courts with respect to any matters to which it has submitted to jurisdiction in
              this Section 16.12 shall be effective only pursuant to service on a Company's registered agent for service of process.  Each of the Companies irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or
              proceeding arising out of this Agreement or the transactions contemplated hereby in the Delaware Courts, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit
              or proceeding brought in any such court has been brought in an inconvenient forum.

           

          Section 16.13   Waiver of Jury Trial.  SUBJECT TO SECTION 13, EACH OF THE COMPANIES HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH
              RESPECT TO ANY JUDICIAL PROCEEDING IN WHICH ANY CLAIM OR COUNTERCLAIM (WHETHER AT LAW, IN EQUITY, IN CONTRACT, IN TORT, OR OTHERWISE) ASSERTED BASED UPON, ARISING FROM, OR RELATED TO THIS AGREEMENT, OR THE COURSE OF DEALING OR RELATIONSHIP
              BETWEEN THE COMPANIES, INCLUDING THE NEGOTIATION, EXECUTION, AND PERFORMANCE OF SUCH AGREEMENT.  EACH OF THE COMPANIES HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER COMPANY HAS REPRESENTED, EXPRESSLY OR
              OTHERWISE, THAT SUCH OTHER COMPANY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND THAT NO COMPANY TO THIS AGREEMENT OR ANY ASSIGNEE, SUCCESSOR, OR REPRESENTATIVE OF ANY COMPANY SHALL REQUEST A JURY TRIAL IN
              ANY SUCH PROCEEDING NOR SEEK TO CONSOLIDATE ANY SUCH PROCEEDING WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS
              CONTEMPLATED BY THIS AGREEMENT, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 16.13.

          Section 16.14   Amendment.  The Companies may amend this Agreement only by a written agreement signed by each party to be bound by the amendment and that identifies itself as an amendment to this
              Agreement.

           

          Section 16.15   Subsidiaries.  If, at any time, Arcosa acquires or creates one or more subsidiaries that are includable in the Arcosa Group, they shall be subject to this Agreement and all references
              to the Arcosa Group herein shall thereafter include a reference to such subsidiaries. If, at any time, Trinity acquires or creates one or more subsidiaries that are includable in the Trinity Group, they shall be subject to this Agreement and
              all references to the Trinity Group herein shall thereafter include a reference to such subsidiaries.

           

          Section 16.16   Successors.  This Agreement shall be binding on and inure to the benefit of any successor by merger, acquisition of assets, or otherwise, to either Company (including but not limited
              to any successor of Trinity or Arcosa succeeding to the Tax attributes of either under Section 381 of the Code), to the same extent as if such successor had been an original party to this Agreement.

           

          Section 16.17   Injunctions.  The Companies agree that irreparable damage would occur in the event that the provisions of this Agreement, including Section 6.01, were not performed in accordance with their specific terms. Accordingly, it is hereby agreed that the Companies shall be entitled to (i) an injunction or injunctions to enforce
              specifically the terms and provisions hereof in any dispute resolution in accordance with Section 13, (ii) provisional or temporary injunctive relief in accordance therewith in any Delaware Court, including an injunction or injunctions to
              prevent breaches of the provisions of this Agreement, including Section 6.01, and (iii) enforcement of any such award of an arbitral tribunal or a
              Delaware Court in any court of the United States, or any other any court or tribunal sitting in any state of the United States or in any foreign country that has jurisdiction, this being in addition to any other remedy or relief to which they
              may be entitled.

           

          Section 16.18   No Reliance on Other Company.  The Companies represent to each other that this Agreement is entered into with full consideration of any and all rights which the Companies may have. 
              The Companies have relied upon their own knowledge and judgment and have conducted such investigations they and their in-house counsel have deemed appropriate regarding this Agreement and their rights in connection with this Agreement.  The
              Companies are not relying upon any representations or statements made by the other Company, or  such other Company's employees, agents, representatives or attorneys, regarding this Agreement, except to the extent such representations are
              expressly set forth or incorporated in this Agreement.  The Companies are not relying upon a legal duty, if one exists, on the part of the other Company (or such other Company's employees, agents, representatives or attorneys) to disclose any
              information in connection with the execution of this Agreement or its preparation, it being expressly understood that neither Company shall ever assert any failure to disclose information on the part of the other Company as a ground for
              challenging this Agreement or any provision hereof.

           

          
            35

            
              

          

          Section 16.19   Consequential Damages.  In no event shall Trinity, Arcosa or their respective Affiliates, officers, directors, employees or other agents be liable under this Agreement for any
              punitive, exemplary, special, incidental, indirect or consequential damages of any kind or nature, and in no event shall Trinity, Arcosa or any of their respective Affiliates, officers, directors, employees or other agents be liable under
              this Agreement for lost profits, opportunity costs, diminution in value or damages based upon a multiple of earnings or similar financial measure, even if under applicable law such lost profits, opportunity costs, diminution in value, or such
              damages would not be considered consequential or special damages; provided, however, that, for the avoidance of doubt, this Section 16.19 shall not limit recovery under this Agreement for any amounts paid or payable to a Tax Authority or any other amounts expressly recoverable under
              this Agreement.

           

          
            36

            
              

          

          IN WITNESS WHEREOF, each Company has caused this Agreement to be executed on its behalf by a duly authorized officer on the date first set
              forth above.

          as contemplated by Section 3.02, will receive credit for such Employee's service with the other Party to the extent that such service was credited to the
          Employee at the date of transfer.

          eligibility, participation, vesting and calculation of benefits with respect to any such Employee.

       

      Section 2.03         Benefit Plans.

          adopt Benefit Plans (and related trusts, if applicable), with benefits that are comparable (or such other standard as is specified in this Agreement with respect to any particular Benefit Plan) to those of the corresponding Trinity Benefit Plans,
          with the exception of (i) the Arcosa Welfare Plans, which shall be established effective January 1, 2019, and (ii)  the Trinity Pension Plans, the treatment of which is specified in Section 5.01 hereof.  The relevant Trinity Benefit Plans are listed on Schedule 2.03(a).  Arcosa may limit participation in any
          such Arcosa Benefit Plan to Arcosa Group Employees and Former Arcosa Group Employees who participated in the corresponding Trinity Benefit Plan immediately prior to the Effective Time. Arcosa shall, or shall cause an applicable member of the
          Arcosa Group to, adopt such other Benefit Plans as specified in this Agreement.

       

      (b)          Information and Operation. Trinity shall provide Arcosa with information describing each Trinity Benefit Plan election made by an Arcosa Group Employee or Former Arcosa Group Employee
          that may have application to Arcosa Benefit Plans from and after the Effective Time, and Arcosa shall use its commercially reasonable efforts to administer the Arcosa Benefit Plans applying those elections. Each Party shall, upon reasonable
          request, provide the other Party and the other Party's respective Affiliates, agents, and vendors all information reasonably necessary to the other Party's operation or administration of its Benefit Plans.

       

      
        9

        
          

      

      (c)          Post-Closing Standard of Compensation and Benefits.  Except as provided herein, during the General Continuation Period, Arcosa shall provide to each Arcosa Group Employee compensation,
          employee benefits under Arcosa Benefit Plans and terms and conditions of employment that, in the aggregate, are substantially similar to the compensation, employee benefits and terms and conditions of employment provided to such employees
          immediately prior to the Effective Time. Notwithstanding the foregoing, during such period, Arcosa may make such changes, modifications or amendments to the applicable Arcosa Benefit Plan as may be required by applicable Law or as are necessary
          and appropriate to reflect the Separation.

       

      (d)          No Duplication or Acceleration of Benefits. Notwithstanding anything to the contrary in this Agreement, the Separation and Distribution Agreement or any Ancillary Agreement, no
          participant in any Arcosa Benefit Plan shall receive service credit or benefits to the extent that receipt of such service credit or benefits would result in duplication of benefits provided to such participant by the corresponding Trinity
          Benefit Plan or any other plan, program or arrangement sponsored or maintained by a member of the Trinity Group. Furthermore, unless expressly provided for in this Agreement, the Separation and Distribution Agreement or in any Ancillary Agreement
          or required by applicable Law, no provision in this Agreement shall be construed to create any right to accelerate vesting or entitlements under any compensation or Benefit Plan, program or arrangement sponsored or maintained by a member of the
          Trinity Group or member of the Arcosa Group on the part of any Employee or Former Employee.

       

      (e)          No Expansion of Participation. Unless otherwise expressly provided in this Agreement, as otherwise determined or agreed to by
          Trinity and Arcosa, as required by applicable Law, or as explicitly set forth in an Arcosa Benefit Plan, an Arcosa Group Employee or Former Arcosa Group Employee shall be entitled to participate in the Arcosa Benefit Plans at the Effective Time
          only to the extent that such Arcosa Group Employee or Former Arcosa Group Employee was entitled to participate in the corresponding Trinity Benefit Plan as in effect immediately prior to the Effective Time, it being understood that this Agreement
          does not expand (i) the number of Arcosa Group Employees or Former Arcosa Group Employees entitled to participate in any Arcosa Benefit Plan or (ii) the participation rights of Arcosa Group Employees or Former Arcosa Group Employees in any Arcosa
          Benefit Plans beyond the rights of such Arcosa Group Employees or Former Arcosa Group Employees under the corresponding Trinity Benefit Plans, in each case, after the Effective Time.

       

      (f)          Transition Services. The Parties acknowledge that the Trinity Group or the Arcosa Group may provide administrative services for
          certain of the other Party's compensation and benefit programs for a transitional period under the terms of the Transition Services Agreement. The Parties agree to enter into a business associate agreement (if required by HIPAA or other
          applicable health information privacy Laws) in connection with such Transition Services Agreement.

          member of the Arcosa Group shall be considered to be a successor to each member of the Trinity Group for purposes of, and a third−party beneficiary with respect to, such Individual Agreement, such that each member of the Arcosa Group shall enjoy

        ASSIGNMENT

              OF EMPLOYEES

       

      Section 3.01         Active Employees.

       

      (a)          Assignment and Transfer of Employees. Trinity shall designate the Arcosa Employees for transfer to a member of the Arcosa Group
          prior to the Distribution Date. Effective no later than immediately prior to the Effective Time and except as otherwise agreed by the Parties, (i) the applicable member of the Trinity Group shall have taken such actions as are necessary to ensure
          that each Arcosa Group Employee is employed by a member of the Arcosa Group as of immediately after the Effective Time, and (ii) the applicable member of the Trinity Group shall have taken such actions as are necessary to ensure that each Trinity
          Group Employee is employed by a member of the Trinity Group as of immediately after the Effective Time. Each of the Parties agrees to execute, and to seek to have the applicable Employees execute, such documentation, if any, as may be necessary
          to reflect such assignment and/or transfer.

       

      (b)          At-Will Status. Nothing in this Agreement shall create any obligation on the part of any member of the Trinity Group or any member of the Arcosa Group to (i) continue the employment of
          any Employee or permit the return from a leave of absence for any period after the date of this Agreement, except as required by applicable Law, or (ii) change the employment status of any Employee from "at-will," to the extent that such Employee
          is an "at-will" employee under applicable Law.

       

      (c)          No Severance. The Parties acknowledge and agree that the Distribution and the assignment, transfer or continuation of the
          employment of Employees as contemplated by this Section 3.01 shall not be deemed an involuntary termination of employment entitling any Arcosa Group Employee
          or Trinity Group Employee to severance payments or benefits.

       

      (d)          Not a Change of Control/Change in Control. The Parties acknowledge and agree that neither the consummation of the Distribution nor
          any transaction contemplated by this Agreement, the Separation and Distribution Agreement or any other Ancillary Agreement shall be deemed a "change of control," "change in control," or term of similar import for purposes of any Benefit Plan
          sponsored or maintained by any member of the Trinity Group or member of the Arcosa Group or for purposes of any Individual Agreement.

      (e)          U.S. Payroll and Related Taxes. With respect to any Arcosa Group Employee or Former Arcosa Group Employee, or group of Arcosa Group
          Employees or Former Arcosa Group Employees, the Parties shall, or shall cause their respective Subsidiaries to, (i) treat Arcosa (or the applicable member of the Arcosa Group) as a "successor employer" and Trinity (or the applicable member of the
          Trinity Group) as a "predecessor," within the meaning of Sections 3121(a)(1) and 3306(b)(1) of the Code, for purposes of taxes imposed under the United States Federal Insurance Contributions Act, as amended ("FICA"), or the United States Federal Unemployment Tax Act, as amended ("FUTA"), (ii) cooperate with
          each other to avoid, to the extent possible, the restart of FICA and FUTA upon or following the Effective Time with respect to each such Arcosa Group Employee for the tax year during which the Effective Time occurs, and (iii) use commercially
          reasonably efforts to implement the alternate procedure described in Section 5 of Revenue Procedure 2004−53; provided, however, that, if and to the extent that Arcosa (or the applicable member of the Arcosa Group) cannot be treated as a "successor employer" to Trinity (or the applicable member of the
          Trinity Group) within the meaning of Sections 3121(a)(1) and 3306(b)(1) of the Code with respect to any Arcosa Group Employee or group of Arcosa Group Employees, (x) with respect to the portion of the tax year commencing on January 1, 2018 and
          ending on the Distribution Date, Trinity will (A) be responsible for all payroll obligations, tax withholding and reporting obligations for such Arcosa Group Employees and (B) furnish a Form W−2 or similar earnings statement to all such Arcosa
          Group Employees for such period, and (y) with respect to the remaining portion of such tax year, Arcosa will (A) be responsible for all payroll obligations, tax withholding and reporting obligations regarding such Arcosa Group Employees and (B)
          furnish a Form W−2 or similar earnings statement to all such Arcosa Group Employees.  Notwithstanding the foregoing, with respect to Trinity Group Employees transferring to the Arcosa Group, Arcosa and Trinity shall utilize the “standard”
          procedure, and such Employees shall receive one W-2 from Trinity for the period from January 1, 2018 to the Distribution Date, and one W-2 from Arcosa for the remainder of the calendar year through December 31, 2018.

       

      Section 3.02         Global No-Hire and Non-Solicitation. Each Party agrees that, for a period of twelve (12) months from the Distribution Date, such Party shall not hire or solicit for employment, or solicit and enter
          into in any contractual arrangement for consulting or other professional services, excluding any contractual arrangements for the provisions of services pursuant to the Transition Services Agreement, any individual who is an Trinity Group
          Employee, in the case of Arcosa, or an Arcosa Group Employee, in the case of Trinity; provided, however, that, without limiting the generality of the foregoing prohibition, this Section 3.02 shall not prohibit (a) hiring or
          soliciting for employment pursuant to generalized solicitations that are not directed to specific Persons or Employees of the other Party, (b) the solicitation and hiring of a Person whose employment was involuntarily terminated by the other
          Party, or (c) the solicitation and hiring of a Person after receipt by the soliciting Party (in advance of any solicitation or, in the case of a response to a general solicitation as permitted under clause (a) above, in advance of any subsequent
          solicitation in connection with the recruiting process) of the express written consent of the senior Human Resources executive of the Party that employs the Person who is to be solicited and/or hired. For the avoidance of doubt, the restrictions
          under this Section 3.02 shall not apply to Former Employees whose termination with Trinity and its Subsidiaries occurred as a result of voluntary retirement
          prior to January 1, 2018.

              Arcosa Common Stock to which such holder would be become entitled pursuant to the Distribution determined in the same manner as if the outstanding Trinity Stock Award was comprised of fully vested shares of Trinity Common Stock as of the
              Distribution Date.

      (f)          Miscellaneous Award Terms. All of the foregoing adjustments shall be effected in accordance with Sections 424 and 409A of the Code.  None of the Separation, the Distribution, the transfer
          of a Transferred Director or any employment transfer described in Section 3.01(a) shall constitute a termination of employment or separation from service for
          purposes of any Trinity Award or any Arcosa Award. After the Effective Time, for each award adjusted under this Section 4.02, any reference to a "change in
          control," "change of control" or similar definition in an award agreement, Individual Agreement or Trinity Equity Incentive Plan applicable to such award (A) with respect to Trinity Awards, shall be deemed to refer to a "change in control,"
          "change of control" or similar definition as set forth in the applicable award agreement, employment agreement or Trinity Equity Incentive Plan, and (B) with respect to Arcosa Awards, shall be deemed to refer to a "Change in Control" as defined
          in the Arcosa Equity Incentive Plan.

       

      (g)          Registration.  Arcosa shall cause a registration statement on Form S-8 (or other appropriate form) to be filed with respect to such issued or issuable shares prior to the Effective Time
          and shall cause such registration to remain in effect for so long as there may be an obligation to deliver shares of Arcosa Common Stock under such Arcosa and/or Trinity Equity Incentive Plans.  Trinity shall use commercially reasonable efforts
          to assist Arcosa in completing such registration.

       

      (h)          Treatment of Dividends/Dividend Equivalents.  Dividends and dividend equivalents with respect to (i) Arcosa Awards shall be paid currently in cash or accrue and be paid in cash by Arcosa
          (including to Trinity Employees, Former Trinity Employees and members of the Trinity Board) and (ii) Trinity Awards shall be paid currently in cash or accrue and be paid in cash by Trinity (including delivery to Arcosa Employees, Former Arcosa
          Employees and Transferred Directors), in each case subject to the terms of the agreements evidencing the respective Trinity Awards immediately prior to the Effective Time.

       

      (i)           Settlement, Delivery; Tax Reporting and Withholding.

       

      
        
          (i)        From and after the Effective Time, Arcosa shall have sole responsibility for delivery of shares of Arcosa Common Stock pursuant to awards issued under an Arcosa Equity Incentive Plan in satisfaction of any
              obligations to deliver such shares under the Arcosa and/or Trinity Equity Incentive Plans (including delivery to Trinity Employees and Former Trinity Employees) and shall do so without compensation from any Trinity Group member.

          (ii)       Upon the vesting, payment or settlement, as applicable, of Arcosa Awards (including with respect to dividends and dividend equivalents), Arcosa shall be solely responsible for ensuring the satisfaction of all
              applicable Tax withholding requirements on behalf of each Arcosa Group Employee or Former Arcosa Group Employee and for ensuring the collection and remittance of applicable employee withholding Taxes to the Trinity Group with respect to each
              Trinity Group Employee or Former Trinity Group Employee (with Trinity Group being responsible for remittance of the applicable employee Taxes and payment and remittance of the applicable employer Taxes relating to Trinity Group Employees and
              Former Trinity Group Employees to the applicable Governmental Authority). Upon the vesting, payment or settlement, as applicable, of Trinity Awards, Trinity shall be solely responsible for ensuring the satisfaction of all applicable Tax
              withholding requirements on behalf of each Trinity Group Employee or Former Trinity Group Employee and for ensuring the collection and remittance of applicable employee withholding Taxes to the Arcosa Group with respect to each Arcosa Group
              Employee or Former Arcosa Group Employee (with Arcosa Group being responsible for remittance of the applicable employee Taxes and payment and remittance of the applicable employer Taxes relating to Arcosa Group Employees and Former Arcosa
              Group Employees to the applicable Governmental Authority).  Following the Effective Time, Trinity shall be responsible for all income Tax reporting in respect of Trinity Awards and Arcosa Awards held by Trinity Group Employees, Former Trinity
              Group Employees and members of the Trinity Board (other than Transferred Directors), and Arcosa shall be responsible for all income Tax reporting in respect of Trinity Awards and Arcosa Awards held by Arcosa Group Employees, Former Arcosa
              Group Employees and Transferred Directors.

           

              

        

      

      (j)           Administration.  Each of Trinity and Arcosa shall establish an appropriate administration system in order to handle delivery of shares in an orderly manner and provide reasonable levels
          of service for equity award holders.  Each of Trinity and Arcosa shall cooperate to (i) unify and consolidate all indicative data and payroll and employment information on regular timetables and make certain that each applicable Person's data and
          records in respect of equity awards are correct and updated on a timely basis and (ii) establish a procedure whereby the other Party shall be promptly informed of the obligation to deliver shares to an Arcosa Employee or Former Arcosa Employee or
          a Trinity Employee or Former Trinity Employee, as the case may be. The foregoing shall include employment status and information required to determine the vesting and forfeiture of awards and Tax withholding/remittance requirements.

       

      (k)          No Effect on Subsequent Awards.  The provisions of this Article IV shall have no effect on the terms and conditions of equity and equity-based awards granted following the Effective Time
          by Trinity or Arcosa.

       

      (l)           Establishment and Approval of Plan.  Prior to the Effective Time, Trinity shall cause Arcosa to adopt the Arcosa Equity Incentive Plan with such terms as are necessary to permit the
          implementation of this Section 4.02.  Trinity agrees to facilitate the adoption and approval of the Arcosa Equity Incentive Plan consistent with the
          requirements of the NYSE.

          Employee for the calendar year including the Distribution Date; provided, however, that a pro rata portion of the bonuses for bonus eligible Arcosa Group Employees shall be funded by Trinity for the level of performance achieved through the
          Distribution Date (as determined by the Trinity Human Resources Committee in its sole discretion).  Each respective employer shall cause the full annual bonus to be paid to its respective bonus eligible employees at the regularly scheduled time
          in March of 2019, it being understood that Arcosa shall independently determine the performance levels achieved for the period commencing on the day following the Distribution Date and ending on December 31, 2018.

       

      Section 4.04         Director Compensation Program.

       

      (a)          Establishment of Arcosa Non-Employee Directors' Compensation Program.  Prior to the Effective Time, Arcosa shall, as it deems
          appropriate, establish a non-employee directors' compensation program for each Arcosa non−employee director as of the Effective Time, including those who served on the Trinity Board immediately prior to the Effective Time but who will no longer
          serve on the Trinity Board following the Effective Time (each, a "Transferred Director").

       

      (b)          Allocation of Liability. Trinity shall be responsible for the payment of any fees for service on the Trinity Board that are earned
          at, before, or after the Effective Time, and Arcosa shall not have any responsibility for any such payments except as otherwise provided in Section 4.02 or Article VI. With respect to any Arcosa non-employee director including a Transferred Director, Arcosa shall be responsible for the payment of any fees for service
          on the Arcosa Board that are earned at any time after the Effective Time and Trinity shall not have any responsibility for any such payments except as otherwise provided in Section

      (a)          Trinity Defined Benefit Pension Plans. The Parties acknowledge that Trinity will retain the Trinity Pension Plans and Arcosa shall
          not be required to establish comparable plans for the benefit of Arcosa Group Employees and Former Arcosa Group Employees following the Effective Time.  Trinity agrees that it shall amend the Trinity Pension Plans which cover Arcosa Group
          Employees in the manner determined by Trinity's Retirement Plan Committee (the "RPC") such that, subject to Section 5.01(b), each Arcosa Group Employee who is an Arcosa Group Defined Benefit Plan Participant shall receive accelerated service credit and/or service credit towards continued benefits after the
          Distribution Date for periods of service with Arcosa, including for the purpose of vesting and growing into the following benefits: early retirement eligibility, disability retirement, special death benefits and military leave benefits.  Prior to
          the Distribution Date, the RPC shall determine, in its sole discretion, the terms of the amendments and the mechanics by which the provisions of this Section 5.01
          shall be implemented, and the Parties shall execute such additional documents as may be required to implement the determination of the RPC.

      (b)          Allocation of Costs.  The pension funding liability, PBGC premiums, compliance, reporting and other administrative costs under the
          Trinity Pension Plans (as amended pursuant to Section 5.01(a)) will be determined periodically by Trinity (and at least annually with respect to required
          funding contributions) and Arcosa will pay the portion allocable (based on applicable data during the applicable period) to the Arcosa Group Defined Benefit Plan Participants to Trinity.  Unless otherwise agreed between the Parties, Arcosa shall
          reimburse Trinity within 20 Business Days of delivery by Trinity to Arcosa of an invoice for the amount due, accompanied by a statement reasonably detailing the costs incurred.  In addition, Arcosa shall be responsible for the data and
          information provided by Arcosa to Trinity (or other third party administrator under the Trinity Pension Plans) with respect to the Arcosa Group Defined Benefit Plan Participants following the Distribution Date.   Trinity shall not be obligated to
          continue to provide the benefits described in Section 5.01(a) with respect to the Arcosa Group Defined Benefit Plan Participants under this Agreement (i) in
          the event of nonpayment by Arcosa, (ii) if Arcosa or a member of the Arcosa Group becomes subject to a proceeding as a debtor under the United States Bankruptcy Code or (iii) in the event of a Change in Control of Arcosa as such term is defined
          in the Arcosa Equity Incentive Plan.

       

      (c)          Plan Fiduciaries and Plan Settlor Functions. For all periods, before, during and after the Effective Time, the Parties agree that
          (i) the fiduciaries of the Trinity Pension Plans shall have the sole authority with respect to the Trinity Pension Plans to determine the plan investments, de-risking strategies, and such other matters as are within the scope of their duties
          under ERISA and the terms of the applicable plan documents and (ii) Trinity or its delegates shall have the sole authority to exercise any and all settlor functions with respect to the Trinity Pension Plans, including, without limitation, the
          authority to amend, freeze or terminate any or all of the Trinity Pension Plans.

       

      (d)          No Loss of Unvested Benefits. The transfer of any Arcosa Group Defined Benefit Plan Participant's employment to the Arcosa Group
          generally shall not result in the loss of that Arcosa Group Defined Benefit Plan Participant's unvested accrued benefits (if any) under the Trinity Pension Plans.

       

      (e)          Administration.  Each of Trinity and Arcosa shall cooperate to establish an appropriate administration system to consolidate and
          transmit to Trinity all indicative data and payroll and employment information on regular timetables and make certain that each applicable Person's data and records are correct and updated on a timely basis.  The foregoing shall include
          employment status, other information required to determine the vesting of, and eligibility for benefits under, the Trinity Pension Plans and all other information necessary or appropriate for the administration of the Trinity Pension Plans.

       

      Section 5.02         Arcosa Profit Sharing Plan.

       

      (a)          Establishment of Plan. Prior to the Effective Time, Arcosa shall adopt the Arcosa Profit Sharing Plan, a tax-qualified, defined

          Board (or its authorized committee or other delegate) evidencing adoption of the Arcosa Profit Sharing Plan and the related trust(s) and the assumption by the Arcosa Profit Sharing Plan of the liabilities described in Section 5.02(c); and (iii) the application for determination with respect to the qualified status of the Arcosa Profit Sharing Plan under Section 401(a) of the Code and the
          tax−exempt status of its related trust under Section 501(a) of the Code.

       

      (c)          Transfer of Account Balances. Not later than 30 days following the Distribution Date (or such later time as mutually agreed by the
          Parties), Trinity shall cause the trustee of the Trinity Profit Sharing Plan to transfer from the trust(s) which forms a part of the Trinity Profit Sharing Plan to the trust(s) which forms a part of the Arcosa Profit Sharing Plan the account
          balances of the Arcosa Group Employees under the Trinity Profit Sharing Plan, determined as of the date of the transfer. Such transfers shall be made in kind, including promissory notes evidencing the transfer of outstanding loans.  Any asset and
          liability transfers pursuant to this Section 5.02(c) shall comply in all respects with Sections 414(l) and 411(d)(6) of the Code.

       

      (d)          Arcosa Profit Sharing Plan Provisions. The Arcosa Profit Sharing Plan shall provide that:

              immediately prior to the Effective Time, and (B) receive credit for purposes of eligibility and vesting for all service credited for those purposes under the Trinity Profit Sharing Plan as of immediately prior to the Distribution Date as if
              that service had been rendered to Arcosa; and

           

            

        

      

      
        
          (ii)       the account balance of each Arcosa Group Employee under the Trinity Profit Sharing Plan as of the date of the transfer of assets from the Trinity Profit Sharing Plan (including any outstanding promissory notes)
              shall be credited to such individual's account balance under the Arcosa Profit Sharing Plan.

           

            

        

      

      (e)          Trinity Profit Sharing Plan after Effective Time. From and after the Effective Time, (i) the Trinity Profit Sharing Plan shall continue to be responsible for liabilities in respect of
          Trinity Group Employees and all Former Employees under the Trinity Profit Sharing Plan, and (ii) subject to Section 2.02(b) hereof, no Arcosa Group Employees
          shall accrue any benefits under the Trinity Profit Sharing Plan. Without limiting the generality of the foregoing, Arcosa Group Employees shall cease to be participants in the Trinity Profit Sharing Plan effective as of the Effective Time.

       

      
        22

          alternatives and such other matters as are within the scope of their duties under ERISA and the terms of the applicable plan documents.

       

      (g)          No Loss of Unvested Benefits. The transfer of any Arcosa Group Employee's employment to the Arcosa Group will not result in loss of that Arcosa Group Employee's unvested benefits (if any)
          under the Trinity Profit Sharing Plan, which benefit liability will be assumed under the Arcosa Profit Sharing Plan as provided herein.

          (i)        As of the Effective Time, Arcosa shall, and shall cause the Arcosa  Supplemental Profit Sharing Plan to, assume all Liabilities under the Trinity Supplemental Profit Sharing Plan for the benefit of Arcosa Group
              Employees, and the Trinity Group and the Trinity Supplemental Profit Sharing Plan shall be relieved of all Liabilities with respect to those benefits. Trinity shall retain all Liabilities under the Trinity Supplemental Profit Sharing Plan

              Liabilities for those benefits. As of the Effective Time, except as otherwise provided in Section 4.02, Trinity shall retain all Liabilities under the
              Director Fees Plan for the benefits of members of the Trinity Board (other than Transferred Directors). From and after the Effective Time, the Transferred Directors shall cease to be participants in the Trinity Director Fees Plan.

      (c)          Prior to or upon the Effective Time, Trinity shall
          cause the grantor or "rabbi" trusts established with respect to benefits provided under the Trinity Supplemental Profit Sharing Plan and/or Trinity Director Fees Plan and Trinity 2005 Director Fees Plan to transfer to a corresponding "rabbi"
          trust established by Arcosa all assets held in the Trinity grantor trust(s) in respect of Arcosa Group Employees and Transferred Directors participating in the aforementioned Trinity Supplemental Profit Sharing Plan and/or Trinity Director Fees
          Plan and Trinity 2005 Director Fees Plan prior to the Distribution Date.

       

      Section 6.02         Retained Nonqualified Plans. The Parties acknowledge that Trinity will retain the Trinity Supplemental Retirement Plan and Transition Compensation Plan, and Arcosa will not assume any Liabilities in
          respect of the Trinity Supplemental Retirement Plan or Transition Compensation Plan.

       

      Section 6.03         No Distributions.  The transfer of any Arcosa Group Employee's employment to the Arcosa Group will not result in (i) the loss of that Arcosa Group Employee's unvested benefits (if any) under any
          Trinity nonqualified deferred compensation plan, which benefit liability will be assumed under the applicable Arcosa nonqualified deferred compensation plan as provided herein. For purposes of determining when a distribution is required from an
          Arcosa nonqualified deferred compensation plan described in this Article VI, Arcosa Group Employees and Transferred Directors will be treated as not having experienced a separation from service until such Arcosa Group Employee or Transferred
          Director has separated from service from the Arcosa Group.  Accordingly (x) no Arcosa Group Employee shall be entitled to a distribution of his or her benefit under any Trinity nonqualified deferred compensation plan or Arcosa nonqualified
          deferred compensation plan as a result of his or her transfer of employment and (y) no Transferred Director shall be entitled to a distribution of his or her benefit under the Trinity Director Fees Plan, Trinity 2005 Director Fees Plan, Arcosa
          Director Fees Plan or Arcosa 2005 Director Fees Plan as a result of his or her transfer.

          (i)        with respect to initial enrollment, waive (A) all limitations as to preexisting conditions, exclusions, and service conditions with respect to participation and coverage requirements applicable to any Arcosa
              Group Employee or Former Arcosa Group Employee, other than limitations that were in effect with respect to the Arcosa Group Employee or Former Arcosa Group Employee under the applicable Trinity Welfare Plan as of immediately prior to the
              Effective Time, and (B) any waiting period limitation or evidence of insurability requirement applicable to an Arcosa Group Employee or Former Arcosa Group Employee other than limitations or requirements that were in effect with respect to
              such Arcosa Group Employee or Former Arcosa Group Employee under the applicable Trinity Welfare Plans as of immediately prior to the Effective Time; and

           

            

        

      

      
        
          (ii)       take into account with respect to aggregate annual, lifetime, or similar maximum benefits available under the Arcosa Welfare Plans, an Arcosa Group Employee's or Former Arcosa Group Employee's prior claim
              experience under the Trinity Welfare Plans and any Benefit Plan that provides leave benefits for purposes of satisfying all aggregate annual, lifetime or maximum out-of-pocket requirements applicable to such Arcosa Group Employee or Former
              Arcosa Group Employee and his or her covered dependents for the applicable plan year to the same extent as such expenses were taken into account by Trinity for similar purposes as if such amounts had been paid in accordance with such Arcosa
              Welfare Plan.

        (d)          U.S. Flexible Spending Accounts. The Parties shall use commercially reasonable efforts to ensure that as of the
            Effective Time any health or dependent care flexible spending accounts of Arcosa Group Employees (whether positive or negative) (the "Transferred Account Balances")

            under Trinity Welfare Plans that are health or dependent care flexible spending account plans are transferred, as soon as practicable after January 1, 2019, from
            the Trinity Welfare Plans to the corresponding Arcosa Welfare Plans. Such Arcosa Welfare Plans shall assume responsibility as of January 1, 2019 for all outstanding health or dependent care claims under the corresponding Trinity Welfare Plans
            of each Arcosa Group Employee for the year in which the Effective Time occurs and shall assume and agree to perform the obligations of the corresponding Trinity Welfare Plans from and after January 1, 2019. As soon as practicable after January
            1, 2019, and in any event within 30 days after the amount of the Transferred Account Balances is determined or such later date as mutually agreed upon by the Parties, Arcosa shall pay Trinity the net aggregate amount of the Transferred Account
            Balances, if such amount is positive, and Trinity shall pay Arcosa the net aggregate amount of the Transferred Account Balances, if such amount is negative.

      

       

      (e)          Allocation of Welfare Assets and Liabilities. Effective as of the Effective Time, the Arcosa Group shall assume
            all Liabilities relating to, arising out of or resulting from health and welfare coverage or claims incurred by or on behalf of Arcosa Group Employees or their covered dependents or Former Arcosa Group Employees or their covered dependents
            (other than such Former Arcosa Employees who have retired from Trinity prior to the Effective Time under the Trinity Profit Sharing Plan or a Trinity Pension Plan (each, a "Retiree")) including but not limited to all COBRA costs under the Trinity Welfare Plans or Arcosa Welfare Plans before, at, or after the
            Effective Time; it being understood that the Arcosa Group shall reimburse Trinity for all amounts under the Trinity Welfare Plans attributable to Arcosa Group Employees and Former Arcosa Group Employees other than the Retirees as more fully set
            forth in the Transition Services Agreement with respect to claims incurred during the period from the Distribution Date through December 31, 2018 (including any applicable run out period).  For the avoidance of doubt, COBRA coverage for
          Arcosa Group Employees or their covered dependents or Former Arcosa Group Employees or their covered dependents (other than a Retiree) will be provided by the Trinity Welfare Plans from the Distribution Date through December 31, 2018, but as of
          January 1, 2019 coverage for all Arcosa Group Employees or their covered dependents or Former Arcosa Group Employees or their covered dependents (other than a Retiree) including COBRA coverage shall transfer to the Arcosa Welfare Benefit Plans.

       

      Section 7.02         U.S. COBRA and HIPAA. The Trinity Group shall continue to be responsible for complying with, and providing coverage pursuant to, the health care continuation requirements of COBRA, the certificate of
          creditable coverage requirements of HIPAA, and the corresponding provisions of the Trinity Welfare Plans with respect to any Trinity Group Employees (and their covered dependents) and any Former Trinity Group Employees (and their covered
          dependents) who incur a qualifying event under COBRA before, as of, or after the Effective Time. Effective as of January 1, 2019, the Arcosa Group shall assume responsibility for complying with, and providing coverage pursuant to, the health care
          continuation requirements of COBRA, the certificate of creditable coverage requirements of HIPAA, and the corresponding provisions of the Arcosa Welfare Plans with respect to any Arcosa Group Employees or Former Arcosa Group Employees (and their
          covered dependents) who incur a qualifying event or loss of coverage under the Trinity Welfare Plans and/or the Arcosa Welfare Plans before, as of, or after the Effective Time. The Parties agree that the consummation of the transactions
          contemplated by the Separation and Distribution Agreement shall not constitute a COBRA qualifying event for any purpose of COBRA.

          and required payments related thereto, for each Trinity Group Employee.  Notwithstanding the generality of the foregoing, Trinity shall fund the legacy banked vacation benefits accrued by Arcosa Group Employees as of the Distribution Date.

              For purposes of FMLA (or other applicable state/municipal leaves), Trinity (either in its own capacity or through its third party administrator for leaves of absence) agrees to treat Arcosa Group Employees as if Arcosa were a successor. 
              Specifically, Arcosa Group Employees who are out on approved FMLA leave (or who have approved intermittent FMLAs) shall not need to reapply, provide recertifications, or reestablish eligibility unless they would do so in the ordinary course
              of their employment with Trinity or Arcosa.  Arcosa agrees to provide, or shall cause its employees provide, each Arcosa Group Employee’s work schedule, FMLA usage, and other contact information required to comply with the calculations and
              notice provisions prescribed under the FMLA.  At the end of 2018, Arcosa will provide to the Arcosa Group Employees new instructions on how to apply for and/or continue their leaves of absence.  As soon as administratively possible and not later than the January 1, 2019, the Trinity Group shall provide to the Arcosa Group  (or its designated representative) copies of all records pertaining to the Trinity Group leave of absence programs and FMLA with respect to all Arcosa Group Employees to the extent such records have not been provided previously to
                the Arcosa Group, including: information on all leaves of absence for Arcosa Group Employees, including: all notices or other documents provided to employees seeking approval or on approved leave, all information received from
              employees seeking approval or on approved leave, leave of absence tracking for all of 2018, and any and all related notes of conversations with such Arcosa Group Employees.

              limited to: (i) the Arcosa Group shall adopt, and shall cause each member of the Arcosa Group to adopt, leave of absence programs; (ii) the Arcosa Group shall honor, and shall cause each member of the Arcosa Group to honor, all terms and
              conditions of leaves of absence which have been granted to any Arcosa Employee under a Trinity leave of absence program or FMLA before January 1, 2019, including such leaves that are to commence after January 1, 2019; and (iii) the Arcosa
              Group shall recognize all periods of service of each Arcosa Group Employee with the Trinity Group to the extent such service is recognized by the Trinity Group
              for the purpose of eligibility for leave entitlement under the Trinity Group leave of absence programs and FMLA.

          compensation, regardless of whether the event giving rise to the Liability occurred before, at or after the Effective Time.

          Former Arcosa Employee prior to the Effective Time.

          their commercially reasonable efforts to replicate such insurance contracts for Arcosa (except to the extent that changes are required under applicable state insurance Laws or filings by the respective insurers) and to maintain any pricing
          discounts or other preferential terms for both Trinity and Arcosa for a reasonable term. Neither Party shall be liable for failure to obtain such insurance contracts, pricing discounts, or other preferential terms for the other Party. Each Party
          shall be responsible for any additional premiums, charges, or administrative fees that such Party may incur pursuant to this Section 7.06.

       

      Section 7.07         Third-Party Vendors. To the extent that any Trinity Welfare Plan is administered by a third-party vendor, the Parties will cooperate and use their commercially reasonable efforts to replicate any
          contract with such third-party vendor for Arcosa and to maintain any pricing discounts or other preferential terms for both Trinity and Arcosa for a reasonable term. Neither Party shall be liable for failure to obtain such pricing discounts or
