In any action or proceeding between Grantor and Secured Party arising out of or relating to this Agreement, the prevailing party shall be entitled to recover its reasonable attorneys’ and other costs and expenses incurred, in addition to any other relief to which it may be entitled. All amendments to this Agreement must be in writing signed by both Secured Party and Grantor. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, are an original, and all taken together, constitute one Agreement. To the extent that any provision of this Agreement conflicts with any provision of the Loan Agreement, the provision giving Secured Party greater rights or remedies shall govern, it being understood that the purpose of this Agreement is to add to, and not detract from, the rights granted to Secured Party under the Loan Agreement. This Agreement, the Loan Agreement and the other Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements. All prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of this Agreement, the Loan Agreement and the other Loan Documents merge into this Agreement, the Loan Agreement and the other Loan Documents.

     5. Choice Of Law, Venue and Jury Trial Waiver. California law governs this Agreement without regard to principles of conflicts of law. Grantor and Secured Party each submit to the exclusive jurisdiction of the State and Federal courts in Santa Xxxxx County, California; provided, however, that

-3-

nothing in this Agreement shall be deemed to operate to preclude Secured Party from bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Secured Party. Grantor expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Grantor hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Grantor hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Grantor at the address set forth in Section 10 of the Loan Agreement and that service so made shall be deemed completed upon the earlier to occur of Grantor’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid.

     TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW GRANTOR AND SECURED PARTY EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

     WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’ AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, mutually selected by the parties (or, if they cannot agree, by the Presiding Judge of the Santa Xxxxx County, California Superior Court) appointed in accordance with California Code of Civil Procedure Section 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in Santa Xxxxx County, California; and the parties hereby submit to the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Santa Xxxxx County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and order applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to the California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

     6. Name Change of Xxxx Acquisition to UCT Xxxxxx Engineering LLC. Substantially simultaneously with the consummation of the Acquisition, the name of Xxxx Acquisition LLC shall be changed to UCT Xxxxxx Engineering LLC by filing such name change with the Secretary of State of the

-4-

State of Delaware. From and after such time, all references to Xxxxxx shall mean UCT Xxxxxx Engineering LLC, a Delaware limited liability company.
