(g) Non-Competition; Non-Solicitation. In consideration of the benefits of this Agreement to Seller and in order to induce Purchaser to enter into this Agreement, Seller hereby covenants and agrees that from and after the Closing and until the fifth anniversary of the Closing Date, neither Seller nor any of its affiliates (including, without limitation, Quixote Corporation, and any present or future subsidiary of Quixote Corporation) shall, directly, or indirectly, as a partner, stockholder, proprietor, consultant, joint venturer, investor or in any other capacity:

employment published in a journal, newspaper or other publication of general circulation and not specifically directed towards such employees shall not be deemed to constitute solicitation for purposes of this subparagraph (ii); or

(iii) Solicit any customer of Purchaser to purchase products or services which could be supplied by Purchaser from the Product Line; provided however, notwithstanding the provisions of this paragraph (g)(iii), Seller and its affiliates shall have the right to continue to solicit for and sell products of the Product Line if those products are components of an integrated system.

(h) Confidentiality. From and after the Closing, Seller and its affiliates shall keep confidential and not disclose to any other person or entity or use for their own benefit or the benefit of any other person or entity, any information regarding the Product Line or Seller’s conduct of the business or manufacturing and selling products of the Product Line. The obligation of Seller under this paragraph shall not apply to information which: (i) is or becomes generally available to the public without breach of the commitment provided for in this paragraph; or (ii) is required to be disclosed by law, order or regulation of a court or tribunal or government authority; provided, however, that in any such case, Seller shall notify Purchaser as early as reasonably practicable prior to disclosure to allow Purchaser to take appropriate measures to preserve the confidentiality of such information.

(i) Injunctive Relief. Seller acknowledges that, given the nature of the business of manufacturing and selling the products of the Product Line, the covenants contained in this Section paragraphs (g) and (h) contain reasonable limitations as to time, geographical area and scope of activity to be restrained, and do not impose a greater restraint than is necessary to protect and preserve for the benefit of Purchaser the goodwill of Seller and to protect the legitimate business interests of Purchaser. If, however, paragraphs (g) or (h) (or any portion thereof) is determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too long a period of time or over too large a geographic area or by reason of its being too extensive in any other respect or for any other reason it will be interpreted to extend only over the longest period of time for which it may be enforceable and/or over the largest geographical area as to which it may be enforceable and/or to the maximum extent in all other aspects as to which it may be enforceable, all as determined by such court and in such action. Seller agrees that Purchaser’s remedies at law for any breach or threat of breach by Seller or any of its affiliates of the provisions of paragraph (h) or (i) will be inadequate, and that Purchaser shall be entitled to an injunction or injunctions, without the necessity for the posting of a bond or other collateral security, to prevent breaches of the provisions of paragraphs (g) and (h) and to enforce specifically the terms and provisions thereof.

buy such products from Purchaser, which Purchaser may or may not have to accept; and (iii) if Purchaser accepts such order, Purchaser will pay Seller or its affiliates a 5% commission on such purchase order.

All representations and warranties shall survive the Closing (and none shall merge into any instrument of conveyance) regardless of any investigation or lack of investigation by any of the parties hereto. The failure in any one or more instances of a party to insist upon performance of any of the terms, covenants or conditions of this Agreement, to exercise any right or privilege in this Agreement conferred, or the waiver by said party of any breach of any of the terms, covenants or conditions of this Agreement, shall not be construed as a subsequent waiver of any such terms, covenants, conditions, right or privileges, but the same shall continue and remain in full force and effect as if no such forbearance or

waiver had occurred. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party.

(f) Applicable Law. This Agreement shall be governed and controlled as to validity, enforcement, interpretation, construction, effect and in all other respects by the internal laws of the State of California applicable to contracts made in that State, without regard to any conflict of law principles of the State of California.

(g) Consent to Jurisdiction. This Agreement has been executed and delivered in and shall be deemed to have been made in California. Each of the parties agrees to the exclusive jurisdiction of any state or Federal court within Los Angeles, California, with respect to any claim or cause of action arising under or relating to this Agreement, and waives personal service of any and all process upon it, and consents that all services of process be made by registered or certified mail or delivered by hand, directed to it as provided in the following sentence, and service so made shall be deemed to be completed when received. Process to be served upon Seller shall be mailed or delivered c/o Anne Hamblin Schiave, Holland & Knight, LLP, 131 S. Dearborn Street, Chicago, Illinois 60603. Process to be served upon Purchaser shall be mailed or delivered to Vicki Dallas, Rutan & Tucker, 611 Anton Boulevard, Suite 1400, Costa Mesa, CA 92626. Each of the parties waives any objection based on forum non conveniens and waives any objection to venue of any action instituted hereunder. Nothing in this paragraph shall affect the right to serve legal process in any other manner permitted by applicable law.

(h) Waiver of Trial by Jury. Each of the parties waives the right to a jury trial in connection with any suit, action or proceeding seeking enforcement of such party’s rights under this Agreement.

(i) Binding Effect. This Agreement shall inure to the benefit of and be binding upon the parties hereto, and their successors and permitted assigns. Nothing in this Agreement, express or implied, is intended to confer on any person other than the parties hereto, and their respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement.

(j) Assignment. This Agreement shall not be assignable by either party without the prior written consent of the other party. Notwithstanding the foregoing, Purchaser may assign this Agreement to any of its affiliates, or to a purchaser of substantially all of its assets. Any permitted assignee will be obligated to assume the obligations of the assignor, and the assignor shall remain liable performance of all obligations of the assignee.

(k) Amendments. This Agreement shall not be modified or amended except pursuant to an instrument in writing executed and delivered on behalf of each of the parties hereto.

(l) Headings. The headings contained in this Agreement are for convenience of reference only and shall not affect the meaning or interpretation of this Agreement.

(m) Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any

provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction so as to best give effect to the intent of the parties under this Agreement.

(n) Counterparts. Counterpart copies of this Agreement may be signed by all Parties and signature pages exchanged by facsimile or email. The Parties intend and agree that counterpart copies signed and exchanged as provided in the preceding sentence shall be fully binding. Counterpart originals of this Agreement shall be exchanged by U.S. mail or express service at the earliest reasonable time following the exchange of signature pages by facsimile or email, each of which shall be an original and all of which together shall constitute the one and same instrument.

(o) No Strict Construction. The parties hereto jointly participated in the negotiation and drafting of this Agreement. The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their collective mutual intent, this Agreement shall be construed as if drafted jointly by the parties hereto, and no rule of strict construction shall be applied against any person or entity.

(p) Gender. As used in this Agreement, the masculine, feminine or neuter gender shall be deemed to include the others whenever the context so indicates or requires.

(q) Interpretation. Whenever the term “include” or “including” is used in this Agreement, it shall mean “including, without limitation,” (whether or not such language is specifically set forth) and shall not be deemed to limit the range of possibilities to those items specifically enumerated. The words “hereof”, “herein” and “hereunder” and words of similar import refer to this Agreement as a whole and not to any particular provision. Terms defined in the singular have a comparable meaning when used in the plural and vice versa.

(r) The parties hereby waive compliance with the California Bulk Sales law. Purchaser will pay all of the Assumed Liabilities and Seller will pay the Excluded Liabilities.

IN WITNESS WHEREOF, the parties have executed this Asset Purchase Agreement on the date first above written.
