(c) The Underwriter will indemnify and hold harmless the Company and the Selling Stockholder against any losses, claims, damages or liabilities to which the Company or the Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Basic Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, the Registration Statement, the Basic Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use therein; and will reimburse the Company and the Selling Stockholder for any legal or other expenses reasonably incurred by the Company or the Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred.

(d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party

(who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(e) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriter on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (d) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Stockholder on the one hand or the Underwriter on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Stockholder and the Underwriter agree that it would not be just and equitable if contributions pursuant to this subsection (e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of such untrue or

alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f) The obligations of the Company and the Selling Stockholder under this Section 9 shall be in addition to any liability which the Company and the Selling Stockholder may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Underwriter within the meaning of the Act; and the obligations of the Underwriter under this Section 9 shall be in addition to any liability which the Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company or the Selling Stockholder within the meaning of the Act.

10. If the Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder, the Underwriter may arrange for another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by the Underwriter, the Underwriter does not arrange for the purchase of such Shares, then the Selling Stockholder shall be entitled to a further period of thirty-six hours within which to procure another party or other parties to purchase such Shares on such terms. In the event that, within the respective prescribed periods, the Underwriter notifies the Selling Stockholder that the Underwriter has so arranged for the purchase of such Shares, or the Selling Stockholder notifies the Underwriter that the Selling Stockholder has so arranged for the purchase of such Shares, the Underwriter or the Selling Stockholder shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which in the Underwriter’s opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

11. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Selling Stockholder and the Underwriter, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Underwriter or any controlling person of the Underwriter, or the Company, the Selling Stockholder, or any officer or director or controlling person of the Company or any controlling person of the Selling Stockholder, and shall survive delivery of and payment for the Shares.

12. If this Agreement shall be terminated pursuant to Section 10 hereof, neither the Company nor the Selling Stockholder shall then be under any liability to the Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason the Shares are not delivered by or on behalf of the Selling Stockholder as provided herein, the Selling Stockholder will reimburse the Underwriter for all out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred by the Underwriter in making preparations for the purchase, sale and delivery of the Shares, but the Company and the Selling Stockholder shall then be under no further liability to the Underwriter except as provided in Sections 7 and 9 hereof.

13. In all dealings with the Selling Stockholder hereunder, the Underwriter and the Company shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of the Selling Stockholder made or given by any or all of the Attorneys-in-Fact for the Selling Stockholder.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriter shall be delivered or sent by mail, telex or facsimile transmission to the Underwriter at , New York, New York , Attention: ; if to the Selling Stockholder shall be delivered or sent by mail, telex or facsimile transmission to counsel for the Selling Stockholder at Duchossois Industries Inc., 845 Larch Avenue, Elmhurst, Illinois 60126, Attention: David L. Filkin, Vice President & General Counsel, Facsimile Number: (630) 530-6051, with a copy to Jones Day, 77 West Wacker, Chicago, Illinois 60601, Attention: Elizabeth C. Kitslaar, Facsimile Number: (312) 782-8585, and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to the Underwriter pursuant to Section 9(d) hereof shall be delivered or sent by mail, telex or facsimile transmission to the Underwriter at its address. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriter, the Company and the Selling Stockholder and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and each person who controls the Company, the Selling Stockholder or the Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from the Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

16. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

17. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

18. The Company and the Selling Stockholder are authorized, subject to applicable law, to disclose any and all aspects of this potential transaction that are necessary to support any U.S. federal income tax benefits expected to be claimed with respect to such transaction, and all materials of any kind (including tax opinions and other tax analyses) related to those benefits, without the Underwriter imposing any limitation of any kind.

19. The Company agrees with the Underwriter and the Selling Stockholder that if the Underwriter complies with the selling restrictions set forth in a separate writing previously agreed between the parties, then each sale of any Shares by the Selling Stockholder, the Underwriter or any initial purchaser or subsequent holder of the Shares shall conclusively be deemed to comply with any and all requirements, restrictions, conditions and other provisions contained in, and to not be prohibited by, the Stockholders Agreement, dated as of October 26, 2001 and as amended as of November 5, 2001 (the “Stockholders Agreement”), between the Company, TCMC, Inc., and TIC I, LLC Prior to the closing, the Company shall cause its transfer agent to terminate the stop transfer instructions and remove all restrictive legends set forth on certificates representing the Shares and agrees that no initial purchaser or subsequent holder of Shares (in each case excluding Newco, a Related Person with respect to Newco or a Family Affiliate (as such terms are defined in the Stockholders Agreement)) shall be bound by, or required to become a party to, the Stockholders Agreement.

20. The Selling Stockholder acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Selling Stockholder, on the one hand, and the Underwriter, on the other, (ii) in connection therewith and with the process leading to such transaction the Underwriter is acting solely as a principal and not the agent or fiduciary of the Selling Stockholder, (iii) the Underwriter has not assumed an advisory or fiduciary responsibility in favor of the Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether the Underwriter has advised or is currently advising the Selling Stockholder on other matters) or any other obligation to the Selling Stockholder except the obligations expressly set forth in this Agreement and (iv) the Selling Stockholder has consulted its own legal and financial advisors to the extent it deemed appropriate. The Selling Stockholder agrees that it will not claim that the Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Selling Stockholder, in connection with such transaction or the process leading thereto.

21. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Selling Stockholder and the Underwriter with respect to the subject matter hereof.

22. The Company, the Selling Stockholder and the Underwriters hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

23. The Underwriter agrees with the Selling Stockholder that it will not sell any Shares other than in compliance with the selling restrictions contained in the separate writing referred to in Section 19 above.

Re: Trinity Industries, Inc. — Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that , as the underwriter (the “Underwriter”), proposes to enter into an underwriting agreement (the “Underwriting Agreement”) with Trinity Industries, Inc., a Delaware corporation (the “Company”), and TIC I, LLC and TIC II, LLC (together, the “Selling Stockholder”) for a public offering of shares of common stock, par value $1.00 per share, of the Company (the “Common Stock”) pursuant to Registration Statement on Form S-3 (Registration Number 333- ), which has been filed with the Securities and Exchange Commission.

In consideration of the agreement by the Underwriter to offer and sell the shares of Common Stock, the undersigned agrees that, during the period beginning from the date of Underwriting Agreement and continuing to and including the date 30 days after the date of the Prospectus (as defined in the Underwriting Agreement), the undersigned will not offer, sell, contract to sell or otherwise dispose of, except as provided hereunder, any securities of the Company that are substantially similar to the shares of Common Stock, including but not limited to any securities that are convertible into or exchangeable for, or that represent the right to receive, stock or any such substantially similar securities (other than pursuant to equity benefit plans existing on, or upon the conversion or exchange of convertible or exchangeable securities outstanding as of the date hereof) (collectively, the “Undersigned’s Shares”), without the Underwriter’s prior written consent.

The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such shares of Common Stock would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from the shares of Common Stock or other securities.
