Exhibit 10.4

SEVERANCE AND NON-COMPETITION AGREEMENT

THIS SEVERANCE AND NON-COMPETITION AGREEMENT, dated as of July 25, 2008 (the “Agreement”), is by and between Quixote Corporation, a Delaware corporation having its principal offices at 35 East Wacker Drive, Chicago, IL 60601 (“Quixote”), and Leslie J. Jezuit, an Executive of the Company (“Executive”).

WHEREAS, the Executive is a key employee of Quixote who possesses valuable proprietary knowledge of Quixote, its business and operations and the markets in which Quixote competes; and

WHEREAS, the Board of Directors of Quixote (the “Board”) has recognized and continues to recognize that the Executive’s contribution to the growth and success of Quixote has been, and is expected to continue to be, substantial and desires to assure Quixote of the Executive’s continued employment by assuring him of fair treatment if that relationship is terminated; and

NOW, THEREFORE, in consideration of the foregoing, the mutual covenants and conditions contained herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

1.             Certain Defined Terms.

(a)           Good Reason.  “Good Reason” shall mean either of the events described in (i) and (ii) of this subsection 1(a) occurring without the Executive’s written consent.  The Executive’s termination of employment hereunder shall not be treated as a termination for Good Reason unless (1) the Executive provides notice to Quixote of the existence of the Good Reason no later than sixty (60) days after the occurrence of the event which forms the basis for any termination for Good Reason, and (2) Quixote fails to remedy the Good Reason within thirty (30) days after receipt of notice from the Executive of the existence of the Good Reason (the “Cure Period”), and (3) the Executive tenders his resignation in writing to Quixote within fifteen (15) days after end of the Cure Period:

(b)           Cause.  Quixote shall have “Cause” to terminate the Executive’s employment upon:

For the purpose of this subsection (b), no act, or the failure to act, on the Executive’s part shall be considered “willful” unless done, or omitted to be done, by him not in good faith and without reasonable belief that his action or omission was in the best interest of Quixote or its subsidiaries.

(c)           Disability.  An Executive’s “Disability” shall occur if the Executive is absent from his duties as an Executive of Quixote on a full-time basis for six (6) consecutive months and if he qualifies for long-term disability under Quixote’s long-term disability insurance plan.

(d)           Salary Continuation Period.  The “Salary Continuation Period” shall mean one (1) year from the date of a Termination of the Executive.

2.             Termination.

(a)           Termination of Employment.  If the Executive’s employment (x) is terminated for Good Reason, or (y) is terminated for a reason other than death, Disability, Cause or voluntary resignation not constituting a Good Reason, (a Good Reason termination or termination for a reason other than death, Disability, Cause or voluntary resignation not constituting a Good Reason is referred to herein as a “Termination”), the Executive will be entitled to receive:

(b)           Release Agreement.  Prior to Executive obtaining the right to receive, and in exchange for, the Separation Benefit provided in Section 2(a)(iv), above, Executive will first enter into and execute, and deliver to Quixote, a Release Agreement substantially in the form attached hereto as Exhibit A (the “Release”) upon Executive’s Termination of employment.  Unless the Release is executed by Executive and delivered to Quixote within the time period set

2

forth in Paragraph 15 of the Release, Executive will not receive the payments provided in Section 2(a)(iv) above.

(c)           Termination of Severance and Non-Competition Agreement.  This Severance and Non-Competition Agreement shall terminate on the tenth anniversary of this Agreement if the employment of Executive has not been terminated prior to that date.

3.             Withholding Taxes; Code Section 409A.  All payments made under this Agreement shall be subject to reduction to reflect all federal, state, local and other taxes required to be withheld by applicable law.  Notwithstanding anything to the contrary contained in Section 2, if any payment to the Executive under Section 2 would constitute a “deferral of compensation” under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), (such compensation does not, for example, qualify for the “short-term deferral exception” under Section 409A of the Code) and the Executive is a “specified employee” (as such phrase is defined in Section 409A of the Code), the Executive (or the Executive’s beneficiary) will receive payment of such amounts described in this Section 3 which would otherwise be payable hereunder during the first six (6) months following the Executive’s “separation from service” with Quixote (as such phrase is defined in Section 409A of the Code) upon the first to occur of:  (i) the date which is first date of the seventh month after the effective date of the Executive’s separation from service, or (ii) the date of the Executive’s death; provided however, Quixote shall immediately upon Termination pay such amounts described in this Section 3 into a domestic “rabbi trust” to be held by a mutually-acceptable bank or other third party until the Executive is entitled to receive such payments.

4.             Mitigation.  The Executive shall not be required to mitigate the amount of any payment provided for in this Agreement by seeking other employment or otherwise, nor shall the amount of any payment provided for in this Agreement be reduced by any compensation earned by the Executive as a result of employment by another employer after the date of Termination, or otherwise.

5.             At-Will Employment.  Notwithstanding this Agreement, Executive’s relationship with Quixote continues to be an at-will employment relationship.  Quixote or Executive has the right to terminate Executive’s employment with Quixote at any time with or without Cause and with or without notice.  Nothing in this Agreement confers upon the Executive any right to continue in the employ of Quixote, or in any way limits the rights of Quixote, except as expressly stated herein, to discharge the Executive at any time for any reason whatsoever, with or without cause.

6.             Confidential Information.  The Executive shall at all times hold in a fiduciary capacity for the benefit of Quixote all secret, confidential or proprietary information, knowledge or data relating to Quixote and its respective businesses, which shall have been obtained by the Executive during the Executive’s employment by Quixote and which shall not be or become public knowledge including, but not limited to, information regarding the technology, proprietary methodologies and products, software, other trade secrets, clients, suppliers, customers, consultants and agents of Quixote (the “Confidential Information”).  During the Executive’s employment with Quixote and after Termination of such employment at any time or for any reason, and regardless of whether any payments are made to the Executive under this Agreement as a result of such termination, the Executive shall not, without the prior written consent of

3

Quixote or as may otherwise be required by law or legal process, communicate or divulge any Confidential Information to any person other than Quixote and those designated by it or use any Confidential Information except for the benefit of Quixote.  Immediately upon Termination of the Executive’s employment with Quixote at any time or for any reason, the Executive shall return to Quixote all Confidential Information, including, but not limited to, any and all copies, reproductions, notes or extracts of Confidential Information.  The terms of this Section 6 shall be in addition to, and not a replacement of, the provisions of any Executive confidentiality or inventions agreement with Executive.

7.             Non-Competition.

(a)           Solicitation of Employees.  During the Executive’s employment with Quixote and for a period of twelve (12) months after termination of such employment at any time and for any reason, and regardless of whether any payments are made to the Executive under this Agreement as a result of such Termination, the Executive shall not solicit, participate in or promote the solicitation of any person who was employed by Quixote at the time of the Executive’s Termination of employment with Quixote to leave the employ of Quixote or its subsidiaries, or, on behalf of himself or any other person, hire, employ or engage any such person; provided however that the foregoing restriction shall not prohibit Executive or a firm with which he is employed or affiliated from (i) publishing and receiving responses to a general solicitation for employment in a general circulation newspaper, magazine, website or similar medium, or (ii) hiring a former employee of Quixote who has not been employed by Quixote or its subsidiaries for a period of at least six (6) months.  The Executive further agrees that, during such twelve (12) month period, if a current employee of Quixote contacts the Executive about prospective employment, the Executive will inform such employee that he cannot discuss the matter further without informing Quixote.

(b)           Covenants During Employment.  During the Executive’s employment, the Executive will not compete with Quixote anywhere that Quixote conducts its business.  In accordance with this restriction, but without limiting its terms, during the Executive’s employment, the Executive will not:

4

(c)           Covenants Following Termination.  For a period of one (1) year following the Termination of the Executive’s employment, the Executive will not:

(d)           Indirect Competition.  For the purposes of Sections 7(b) and 7(c), but without limitation thereof, the Executive will be in violation thereof if the Executive engages in any or all of the activities set forth therein directly as an individual on the Executive’s own account, or indirectly as a general partner, joint venturer, employee, agent, salesperson, consultant, officer and/or director of any firm, association, partnership, corporation or other entity, or as a limited partner, member or stockholder of any limited partnership, limited liability company, or corporation in which the Executive or the Executive’s spouse, child or parent owns, directly or indirectly, individually or in the aggregate, more than five percent (5%) of the limited partnership interests, limited liability company interests or outstanding stock, as the case may be.

(e)           Application of Restrictions Respecting Confidential Information, Solicitation and Competition.  The requirements and obligations of the Executive under Section 7 shall be in addition to, and not a limitation under, any other requirements and obligations of the Executive, at law or otherwise.

(f)            Consideration.  The parties agree that for all purposes of this Agreement and otherwise, Executive’s continued employment with Quixote and Quixote’s continued provision of confidential information to Executive are sufficient consideration for this Section 7.  In addition, to the extent that Quixote has an obligation to pay the Separation Benefit under the Agreement, fifty percent (50%) of the Separation Benefit hereunder, or an aggregate amount equal to fifty percent (50%) of such Separation Benefit paid hereunder (to the extent the Separation Benefit is paid in installments), shall be considered the consideration payable to Executive for the covenants in this Section 7 (the “Noncompetition Consideration”), and if the

5

Executive violates any of the covenants set forth in this Section 7, then in addition to and not in limitation of any of its remedies hereunder or under applicable law, Quixote shall have the right to refrain from making any further installments of the Separation Benefit and may recover from Executive any amounts of the Separation Benefit paid to Executive to date up to the amount of the Noncompetition Consideration.  The parties further agree that the allocation of a portion of the Separation Benefit as described above shall not be interpreted as granting to Executive any right to receive additional amounts hereunder.

8.             Rights Apply Only on Termination.  The rights granted under this Severance and Non-Competition Agreement only apply upon a Termination.  This Agreement supercedes that certain letter agreement between Quixote and Executive dated December 18, 1995, which letter agreement is hereby terminated and cancelled.

9.             Governing Law.  This Agreement shall be governed by and construed in accordance with the laws of the State of Illinois applicable to agreements made and to be performed in Illinois, without giving effect to conflicts of law principles.

10.           Headings; Severability.  The section headings of this Agreement are for reference only and are to be given no effect in the construction or interpretation of this Agreement.  If any part or provision of this Agreement shall be declared invalid or unenforceable by a court of competent jurisdiction, said provision or part shall be ineffective to the extent of such invalidity or unenforceability only, without in any way affecting the remaining parts or provisions of this Agreement.

11.           Waiver.  Any party may waive compliance by another party with any of the provisions of this Agreement.  No waiver of any provision shall be construed as a waiver of any other provision.  Any waiver must be in writing.

12.           Binding Effect; Assignment.  This Agreement shall be binding on and inure to the benefit of the parties and their respective successors and permitted assigns.  Nothing in this Agreement shall create or be deemed to create any third party beneficiary rights in any person or entity (including any Executive or person engaged by Quixote in any capacity) not a party to this Agreement.  Quixote will require any successor (whether direct or indirect, by merger, purchase, consolidation or otherwise) of Quixote to make an express assumption of the obligations hereunder and cause any successor (whether direct or indirect, by merger, purchase, consolidation or otherwise) to all or substantially all of the business and/or assets of Quixote to agree to perform all parts and provisions under this Agreement in the same manner and to the same extent that Quixote would be required to perform it if no such succession had taken place.  Failure of Quixote to obtain such agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle Executive to compensation from Quixote in the same amount and on the same terms as he would be entitled to hereunder if he is subject to a Good Reason, and the date on which any such succession becomes effective shall be deemed the date of Termination.  As used in this Agreement, Company shall mean Quixote as hereinbefore defined and any successor to the business and/or assets of Quixote which executes and delivers the agreement provided for in this Section 12, or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law.

6

This Agreement and all rights of the Executive hereunder shall inure to the benefit of, and be enforceable by the Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.  If the Executive should die after any amounts shall become payable to him hereunder, all such amounts, unless otherwise provided for herein, shall be paid in accordance with the terms of this Agreement to the Executive’s devisee, legatee or other designee or, if there be no such devisee or other designee, to the Executive’s estate.

13.           Arbitration.  Any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in Chicago, Illinois in accordance with the American Arbitration Association Employment Law Rules then in effect.  The arbitrator is expressly empowered to render legal or equitable relief requested by the parties, whether on an emergency basis or otherwise, in order to enforce the terms of this Agreement.  Judgment may be entered on the arbitrator’s award in any court having jurisdiction; provided, however, that the Executive shall be entitled to seek specific performance of his right to be paid until the date of Termination during the pendency of any dispute or controversy arising under or in connection with this Agreement.  Nothing in this Section 13 prohibits Quixote from seeking equitable or legal relief in any appropriate court in order to enforce Sections 6 and 7 of this Agreement.

14.           Counterparts.  This Agreement may be signed in any number of counterparts and all such counterparts shall be read together and construed as but one and the same document.

15.           Notices.  All notices and other communications under this Agreement shall be in writing and shall be deemed given when delivered personally, or sent by facsimile transmission, receipt confirmed, one day after sent by recognized overnight courier, or five (5) days after deposit in the United States mail, postage prepaid, registered or certified mail, return receipt requested, to the parties at the following addresses (or to such other address as a party may have specified by notice duly given to the other party in accordance with this provision):

The Separation Benefit shall be subject to all required payroll withholdings.

4.             Consideration. Executive acknowledges that Executive would not be entitled to the Separation Benefit provided for in paragraph 3 above in the absence of Executive’s signing of this Agreement, that the Separation Benefit constitutes a substantial economic benefit to Executive, and that it constitutes good and valuable consideration for the various commitments undertaken by Executive in this Agreement.

It is the intention of the parties and is fully understood and agreed by them that this Agreement includes a General Release of all Claims (with the exception of (i) breaches of this Agreement, (ii) claims for vested benefits, if any, to which Executive is legally entitled under ERISA, and (iii) all obligations of the Company pursuant to that Amended and Restated Change of Control Agreement between the Company and the Executive dated                         , 2008), which Executive holds or previously held against Releasees, or any of them, whether or not they are specifically referred to herein.  No reference herein to any specific claim, statute or obligation is intended to limit the scope of this General Release and, notwithstanding any such reference, and except as set forth in the preceding sentence, this Agreement shall be effective as a full and final bar to all Claims of every kind and

In addition to all other obligations contained in this Agreement, Executive agrees that Executive will not initiate, bring or prosecute any suit or action against any of Releasees in any federal, state, county or municipal court, with respect to any of the Claims released in this Agreement. Notwithstanding the forgoing, nothing in this Agreement shall preclude Executive from bringing suit to challenge the validity or enforceability of this Agreement under the Age Discrimination in Employment Act as amended by the Older Workers Benefit Protection Act.

A-3

authorized officer of the Company, or unless required to comply with any federal, state or local law, rule or order. However, this paragraph will not prohibit Executive from disclosing the terms of this Agreement to Executive’s attorneys, accountants or other tax consultants as necessary for the purpose of securing their professional advice, or in connection with any suit or action alleging a breach of this Agreement.]

A-4

The parties agree that any such modification, restriction or excision may be accomplished by their mutual written agreement or, alternatively, by disposition of a court or other tribunal.
