TERMINATION OF REGISTRATION

     This Post-Effective Amendment No. 1 (this “Post-Effective Amendment”), filed by Quixote Corporation, a Delaware corporation (the “Company”), removes from registration all shares of common stock, $0.01²/₃ par value per share (“Common Stock”), of the Company, registered under the Registration Statement on Form S-8 (Registration Number 333-157301) filed by the Company on February 13, 2009 (the “Registration Statement”) with the U.S. Securities and Exchange Commission, pertaining to the registration of 300,000 shares of Common Stock offered under the Quixote Corporation Incentive Savings Plan (as amended and restated January 1, 2006 and as amended through December 10, 2006), as amended (the “Plan”).

     On December 30, 2009, the Company entered into an Agreement and Plan of Merger with Trinity Industries, Inc., a Delaware corporation (“Parent”), and THP Merger Co., a Delaware corporation (“Purchaser”) and a wholly-owned subsidiary of Parent, providing for, among other things, the merger of Purchaser with and into the Company (the “Merger”), with the Company continuing as the surviving corporation, wholly-owned by Parent. The Merger became effective at 1:43 p.m., Eastern Time, on February 5, 2010 (the “Effective Time”), pursuant to a Certificate of Ownership and Merger filed with the Secretary of State of the State of Delaware.

     At the Effective Time, each share of Common Stock issued and outstanding immediately prior to the Merger was cancelled and (other than shares held in the treasury of the Company or by the Company’s subsidiaries, Parent or Purchaser or shares with respect to which appraisal rights are properly exercised under Delaware law) converted into the right to receive $6.38 per share in cash, without interest and less any applicable withholding taxes.

     The Company has terminated the Plan and hereby removes from registration all securities registered under the Registration Statement that remain unsold as of the date of this Post-Effective Amendment and terminates the effectiveness of the Registration Statement.
