TO THIRD AMENDED AND RESTATED CREDIT AGREEMENT

THIS INCREASE AGREEMENT AND THIRD AMENDMENT TO THIRD AMENDED AND RESTATED CREDIT AGREEMENT (this “Amendment”) is made effective as of December 12, 2016 (the “Effective Date”), among MATRIX SERVICE COMPANY, a Delaware corporation (the “Company”), the undersigned Canadian Borrowers (together with the Company, the “Borrowers”), the Lenders, and JPMORGAN CHASE BANK, N.A., as Administrative Agent (the “Administrative Agent”) for the Lenders, and amends the Third Amended and Restated Credit Agreement dated as of November 7, 2011, among the Company, the Canadian Borrowers, the Administrative Agent and the Lenders, as previously amended by (a) the First Amendment to Third Amended and Restated Credit Agreement dated as of March 13, 2014, and (b) the Second Amendment to Third Amended and Restated Credit Agreement dated as of May 3, 2016 (as so amended, the “Existing Credit Agreement” and, as further amended by this Amendment, the “Credit Agreement”).

The Administrative Agent, the Lenders and the Borrowers agree as follows:

1.Definitions. Capitalized terms used but not defined in this Amendment (including terms used in the preamble) have the meanings provided in the Existing Credit Agreement.

2.Revolving Commitment Increase.

(a) Pursuant to Section 2.04 of the Existing Credit Agreement, the Aggregate Revolving Loan Commitments are increased to $250,000,000.00. Each Lender’s Revolving Loan Commitment is as set forth on the attached Schedule 2.01 to this Amendment, which amends and supersedes Schedule 2.01 to the Existing Credit Agreement in its entirety. After giving effect to the foregoing Revolving Commitment Increase, there is $0 in available capacity for any further Revolving Commitment Increases. The maximum aggregate amount of (i) Canadian Dollar Loans permitted under the Credit Agreement is increased to $50,000,000.00, (ii) Swingline Loans permitted under the Credit Agreement remains $20,000,000.00, and (iii) Canadian Dollar Swingline Loans permitted under the Credit Agreement remains $5,000,000.00.

(b) Each Lender consents to the Revolving Loan Commitments set forth on Schedule 2.01 to this Amendment, to be effective on the Effective Date, and agrees to make allocations among themselves on the Effective Date so that each Lender’s pro rata share of all outstanding Loans is equal to that Lender’s pro rata share of the Revolving Loan Commitments (as amended). The reallocation of the Revolving Loan Commitments and Loans among the Lenders on the Effective Date will be deemed to have been consummated pursuant to an Assignment and Assumption attached as Exhibit A to the Credit Agreement as if the Lenders had executed an Assignment and Assumption with respect to the reallocation.

(c) If, as a result of the reallocation effected under this Section 2, any Lender incurs any loss, cost or expense as a result of any payment of a Eurodollar Loan or CDOR Loan before the last day of the Interest Period applicable thereto (whether such payment is by the Borrowers or by reallocation of the outstanding Eurodollar Loans or CDOR Loans) and such Lender makes a request for compensation, the Borrowers shall pay to the Administrative Agent for the account of such Lender any amounts required to compensate such Lender under Section 2.16 of the Credit Agreement.

Following termination of an Acquisition Adjustment Period, the next Acquisition Adjustment Period may not commence until the first day of the third fiscal quarter following the fiscal quarter in which the prior Acquisition Adjustment Period terminated.

(b) The following is added to the end of Section 5.05 of the Existing Credit Agreement:

Administrative Agent and the Impacted Lender, including, without limitation, evidence of annual renewals of such insurance.

Notwithstanding the foregoing, the Administrative Agent shall not enter into any Mortgage in respect of any real property acquired by the Company or any of its Subsidiaries until the Administrative Agent has received written confirmation from the Impacted Lender that flood insurance due diligence and flood insurance compliance has been completed by the Impacted Lender (such written confirmation not to be unreasonably conditioned, withheld or delayed). If the Impacted Lender has not informed the Administrative Agent and the Company of any outstanding flood diligence requirements by the date that is thirty (30) days after the date on which the Administrative Agent made available to the Lenders (which may be delivered electronically) the following documents in respect of such real property: (i) a completed flood hazard determination from a third party vendor; (ii) if such real property is located in a “special flood hazard area”, (A) a notification to the Company of that fact and (if applicable) notification to the Company that flood insurance coverage is not available and (B) evidence of the receipt by the Company of such notice; and (iii) if such notice is required to be provided to the Company and flood insurance is available in the community in which such real property is located, evidence of required flood insurance with respect to any such Mortgage, Impacted Lender will be deemed to have completed its flood insurance due diligence and flood insurance compliance and to have consented to such Mortgage.

4.Consent and Waiver. The Administrative Agent and the Lenders (a) consent to the Houston Acquisition, (b) agree that, the Houston Acquisition will not constitute a Default or Event of Default under Article VII(d) of the Credit Agreement as a result of Borrowers failing to comply with Section 6.04(h)(vi) of the Credit Agreement, and (c) waive any Default or Event of Default described in the preceding subsection (b) that would otherwise occur as a result of the Houston Acquisition.

5.Houston Acquisition Joinder Documentation and other Related Credit Facility Delivery Requirements. The Administrative Agent and the Lenders agree that, with respect to the Houston Acquisition, the Borrowers shall have seventy-five (75) days after consummation of the Houston Acquisition to comply with the requirements of Section 6.04(h)(ix).

6.Effect of this Amendment; Defaults Unaffected.

Nothing in this Amendment will prejudice, act as, or be deemed to be a waiver of any Default or Event of Default or any right or remedy available to Administrative Agent or any Lender by reason of the occurrence or existence of any Default or Event of Default.
