-5-

Lenders have agreed. Accordingly, Lenders hereby waive the provisions of Section 5.09 of the Credit Agreement as they apply to the New Domestic Subsidiary provided that the conditions set forth in Section 6 of this Amendment are satisfied. This waiver shall be limited precisely as provided for herein (including without limitation any time periods specified) and such waiver shall not be deemed to be a waiver of, amendment to, consent to or modification of (i) any other term or provision of the Credit Agreement or any of the other Loan Documents or (ii) any other event, condition, or transaction on the part of the Borrower or any other Person which would require the consent of the Administrative Agent or any of the Lenders.

Borrower and each Subsidiary signatory hereto understands and agrees that this is a full, final and complete release and agrees that this release may be pleaded as an absolute and final bar to any or all suit or suits pending or which may hereafter be filed or prosecuted by any of the Releasing Parties, or anyone claiming by, through or under any of the Releasing Parties, in respect of any of the matters released hereby, and that no recovery on account of the matters described herein may hereafter be had from anyone whomsoever, and that the consideration given for this release is no admission of liability.

The Administrative Agent, the Issuing Bank and the Lenders who

are parties to the Credit Agreement described below

Ladies and Gentlemen:

We have acted as counsel to Matrix Service Company, a Delaware corporation (the “Borrower”), and its Subsidiaries as follows:

Matrix Service Inc. – an Oklahoma corporation

Matrix Service Industrial Contractors, Inc. – an Oklahoma corporation

Matrix Service Specialized Transport Inc. – a Pennsylvania corporation

I & S, Inc. – a Pennsylvania corporation

Matrix Service Industrial Contractors Canada, Inc., a Delaware corporation

Matrix Service Inc. – an Ontario, Canada corporation

Matrix Service Industrial Contractors ULC – a Nova Scotia, Canada unlimited liability corporation

Matrix Service ULC – an Alberta, Canada unlimited liability corporation

S.M. Electric Company, Inc. – a New Jersey corporation

Matrix Service International, LLC – a Delaware limited liability company

Matrix International Holding, LLC – a Delaware limited liability company

(collectively with the Borrower, the “Clients”), in connection with (i) the Borrower’s execution and delivery of that certain Fourth Amendment to Second Amended and Restated Credit Agreement dated as of March 31, 2011, among the Borrower, the Lenders named therein, and JPMorgan Chase Bank, N.A., as a Lender, Issuing Bank and as Administrative Agent (the “Administrative Agent”) for the Lenders (the “Fourth Amendment”), which amends that certain Second Amended and Restated Credit Agreement dated as of November 30, 2006, as previously amended (as so amended and as further amended by the Fourth Amendment, the “Credit Agreement”) and (ii) the execution by certain of the other Clients of certain other documents, all the documents referenced herein listed as follows (collectively, the “Documents”):

(a) the Fourth Amendment;

(b) Subsidiary Guaranty by Matrix International Holding, LLC, a Delaware limited liability company (“MIH”), of even date with the Fourth Amendment;

(d) Ratification of Security Agreements and Release entered into by each of the Clients other than MIH and the Borrower of even date with the Fourth Amendment; and

(e) Ratification of and Amendment to Subsidiary Guaranty entered into by each of the Clients other than MIH and the Borrower of even date with the Fourth Amendment.

In addition to our review of the Documents, we have also examined and relied upon originals or copies of organizational documents and other records of the Clients as well as such certificates of public officials and officers of the Clients and such other documents and matters as we have deemed necessary or appropriate for purposes of this opinion.

All terms capitalized in this opinion letter without definition have the same meanings as in the Credit Agreement.

In rendering this opinion, we have assumed the following to be true and have conducted no investigation to confirm such assumptions or to determine to the contrary:

A. (i) The authenticity of all documents, instruments and certificates submitted to us as originals, (ii) the conformity with the original documents of all documents, instruments and certificates submitted to us as certified, conformed, photostatic or electronic copies, and (iii) the authenticity of the originals from which all such copies were made.

B. All parties to the Documents (other than the Clients) have full power and authority to execute, deliver and perform their respective obligations under the Documents and under the documents required or permitted to be delivered and performed thereunder, and all such documents have been duly authorized by all necessary action by such parties, have been fully executed by such parties, have been duly delivered by such parties and are or will be valid, binding and enforceable obligations of such parties.

C. All signatures on the Documents (other than those on behalf of the Clients) are genuine.

D. The conduct of the parties to the Documents has and will comply with any requirement of good faith, fair dealing, conscionability and commercial reasonableness.

E. There has not been any mutual mistake of fact or misunderstanding, fraud, duress or undue influence in connection with the Documents.

F. Each party to each of the Documents (other than the Clients) is in good standing under the laws of the jurisdiction in which it is incorporated or organized.

G. The execution, delivery and performance by each party (other than the Clients) of the Documents does not breach, conflict with or constitute a violation of (i) the certificate of incorporation, bylaws or any other charter or organizational document of such party, or (ii) the laws or governmental rules and regulations of any jurisdiction, or (iii) any agreement, instrument or document to which any such party is a party or by which any such party or any of its properties is bound or (iv) any order, judgment or decree to which any such party is subject or by which any of its properties is bound.

In rendering this opinion, we have relied as to matters of fact, to the extent we deem such reliance appropriate, without investigation, upon certificates of public officials and upon affidavits, certificates and written statements of officers and employees of the Borrower and Subsidiaries, including the various factual representations of the Clients set forth in the Documents and the Secretary’s Certificate delivered to the Administrative Agent on behalf of the Clients of even date herewith.

Based upon the foregoing, and subject to the qualifications and limitations set forth herein, we are of the opinion that:

l. Each of the Clients (other than Matrix Service Inc., an Ontario, Canada corporation, Matrix Service Industrial Contractors ULC, a Nova Scotia, Canada unlimited liability corporation, and Matrix Service ULC, an Alberta, Canada unlimited liability corporation, as to which no opinion is expressed in this paragraph 1) is a corporation or limited liability company duly and properly incorporated or organized, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite corporate or limited liability company authority to conduct its business in each jurisdiction in which its business is conducted; and each of the Clients is qualified to do business and is in good standing in each other jurisdiction where the nature of the business conducted by it makes such qualification necessary or appropriate, except where the failure to be so qualified would not have a Material Adverse Effect.

2. The execution and delivery by the Clients of the Documents to which they, or any of them, is a party, and the performance by such Client or Clients, as the case may be, of their respective obligations thereunder, have been duly authorized by proper proceedings on the part of the respective Clients and do not and will not:

(a) require any consent of any of the Clients’ shareholders or members (other than any such consent as has already been given and remains in full force and effect);

(b) violate (i) any United States or Oklahoma law, rule, or regulation, which, in our experience, would normally apply to transactions of the type contemplated by the Documents, (ii) any order, writ, judgment, injunction, decree or award of which we have knowledge that is applicable to or binding upon any of the Clients, (iii) any Clients’ articles or certificate of incorporation or organization, by-laws or other organizational documents, as the case may be, or (iv) the provisions of any indenture, instrument or agreement that has either been listed as an exhibit to any periodic report filed by the Borrower since January 1, 2005 with the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the “Exchange Act Documents”), or is otherwise known to us, to which any of the Clients is a party or is subject, or by which it, or its property, is bound, or conflict with or constitute a default thereunder; or

(c) result in, or require, the creation or imposition of any Lien in, of or on any of the property of any Client pursuant to the terms of any indenture, instrument or agreement binding upon any of the Clients that has been filed as an exhibit to any of the Exchange Act Documents or that is otherwise known to us.

3. The Documents to which any of the Clients is a party have been duly executed and delivered by the Clients identified therein as party thereto and constitute legal, valid and binding obligations of the Clients party thereto, enforceable against such Clients in accordance with their

terms, except to the extent the enforcement thereof may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally and subject also to the availability of equitable remedies if equitable remedies are sought.

4. Except as described in Schedule 3.06 to the Credit Agreement, to our knowledge, there is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or threatened against any of the Clients which, if adversely determined, could reasonably be expected to have a Material Adverse Effect.

5. No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by any Client, is required to be obtained by any Client in connection with the execution and delivery of the Documents, the borrowings under the Credit Agreement, the payment and performance by the Borrower of the Obligations, or the legality, validity, binding effect or enforceability of any of the Documents.

This opinion is subject to the following qualifications and limitations:

(i) The provisions contained in the Documents that permit any person to take action or make determinations, or to benefit from indemnities or similar undertakings, may be subject to requirements that such action be taken or such determinations be made, or that any action or inaction by such person that may give rise to a request for payment under such an indemnity or similar undertaking be taken or not taken, on a reasonable basis and in good faith.

(ii) Under certain circumstances the requirements that the provisions of the Documents may be modified or waived only in writing or only in a specific instance may be unenforceable to the extent that an oral agreement has been effected or a course of dealing has occurred modifying such provisions.

(iii) A court may modify or limit contractual awards of attorneys’ fees.

(iv) We express no opinion with regard to the effect of any (a) federal or state securities and “blue sky” laws and regulations, (b) federal or state antitrust and unfair competition laws and regulations, (c) federal or state pension and employee benefit laws and regulations, (d) federal or state environmental, subdivision, zoning, health, safety or land use laws and regulations, (e) federal or state racketeering laws and regulations and banking laws and regulations, and (f) administrative decisions, and rules and regulations of county and municipal political subdivisions.

(v) With respect to our opinion in paragraph 3 above, we express no opinion as to the enforceability of any Documents that purport to be governed by the laws of any jurisdiction other than the State of Oklahoma or that purport to (a) limit or expand remedies beyond those recognized in Oklahoma; (b) give the right of specific performance; (c) alter rules of civil procedure or evidence; (d) waive defenses or rights; (e) create and govern a trustee or creditor in possession status; (f) create indemnities or exculpate a party from liability for its own wrongful or negligent acts; (g) authorize the secured party to take discretionary independent action for the account of or as an agent or attorney-in-fact for the debtor; (h) limit or expand the rights of set-off; (i) guarantee the performance of acts other than payment of money; (j) limit jurisdiction of the courts, establish any exclusive venue, purport to waive jury trial, or establish evidentiary standards; or (k) provide for the

appointment of a receiver without notice. The invalidity or unenforceability of such provisions should not, in our opinion, substantially interfere with the practical realization of the benefits of the Documents.

(vi) We express no opinion with respect to matters of perfection or priority of liens and security interests in any property of the Borrower and its Subsidiaries.

(vii) With respect to our opinion in paragraph 5, we express no opinion regarding any filings the Lenders would be required to make subsequent to foreclosure in connection with the ownership and operation of the Clients’ assets.

We have not relied upon, nor do we undertake for the purpose of this opinion the responsibility to review, the records of any court or administrative or governmental body to determine the existence of any judicial or administrative proceeding, order, decree, writ or judgment. As to all matters where we refer to “our knowledge” of the existence of any facts, situations or instruments, such knowledge means that after considering the actual knowledge of those attorneys in our firm who have given substantive attention to the Borrower’s affairs, we find no reason to believe that the opinions expressed above are factually incorrect.

We are members of the bar of the State of Oklahoma. Our opinions expressed above are limited to the laws of the State of Oklahoma, the corporate laws of the State of Delaware, the corporate laws of the Commonwealth of Pennsylvania, the corporate laws of the State of New Jersey, and the federal laws of the United States of America, and we do not express any opinion herein concerning the laws of any other jurisdiction. To the extent the opinions expressed in paragraphs 2 and 3 above are governed by the laws of a province of Canada, we have assumed that the applicable law in those jurisdictions is the same as the applicable law in the State of Oklahoma in all relevant respects.

The effective date of this opinion is the date first set forth above, and we do not undertake to advise you of any matter brought to our attention thereafter which would or may modify, in whole or in part, any or all of the foregoing. This opinion is limited to the matters expressly stated herein, and no opinion is implied or may be inferred beyond the matters expressly stated.

This opinion is rendered to the Administrative Agent, the Issuing Bank, the Lenders who are parties to the Credit Agreement and their respective permitted participants and assigns under the Credit Agreement, is for their sole benefit and may only be relied upon by them. At your request, we hereby consent to reliance hereon by any future permitted participant, successor or assignee under the Credit Agreement on the condition and with the understanding that (i) this opinion speaks only as of the date hereof, (ii) we have no responsibility or obligation to update this opinion, to consider its applicability or correctness to any person other than those named in the preceding sentence, or to take into account changes in law, facts or any other developments of which we may later become aware, and (iii) any such reliance by a future participant, successor or assignee must be actual and reasonable under the circumstances existing at the time of the applicable participation, assignment or transfer, including any changes in law, facts or any other developments known to or reasonably knowable by the participant, assignee or transferee at such time.

This opinion is not to be quoted in whole or in part or otherwise referred to, nor is it to be filed with or delivered or communicated to any government agency (other than any government agency with regulatory authority as to any of the Lenders or as may otherwise be required by law) or any other person, without our prior written consent.

Very truly yours,

XXXXXX & XXXXXXX, LLP
