Mistras Group Severance Plan

[Modified February 28, 2018]

Due to the competitive nature of the NDT business and the need for executive and managerial talent in the industry, executives and managers of Mistras Group, Inc. (“Mistras”) and its subsidiaries (Mistras and its subsidiaries are collectively referred to as the “Company”) have been and will continue to be recruited by other companies. In order to attract and retain executive and managerial talent, the Compensation Committee of the Board of Directors of Mistras, in consultation with management, has implemented this severance plan (the “Plan”). This Plan is designed to provide its participants with some level of continued income and benefits upon the termination of their employment with the Company under certain circumstances.

Participants who receive the benefit of this Plan (“Participants”) are U.S. based full time employees of the Company who are:

Chief Executive Officer

Other Executive Officers

Senior Vice Presidents

Corporate / Group Vice Presidents

Other managers or divisional vice presidents selected by the CEO and approved by the Compensation Committee

If any Participant is party to an individual agreement with the Company that provides for severance benefits in the event of termination of employment with the Company, the individual will not be eligible to participate in the Plan until the termination or expiration of the agreement.

Severance benefits are payable to a Participant pursuant to this Plan in the following circumstances:

A Participant’s employment with the Company is terminated by the Company without Cause, with “Cause” being any of the following:

A willful act or omission by a Participant means an act or omission not in good faith and without reasonable belief that the action or omission was in the best interest of the Company.

The Participant’s employment with the Company is terminated by the Participant for “Good Reason,” with “Good Reason” being any of the following:

The Plan does not apply to the termination of employment under any other circumstances or for any reason except as expressly enumerated above. This Plan does not apply to the termination of a Participant’s employment due to the Participant’s death or disability. Disability means the Participant cannot perform, with reasonable accommodations, the essential and customary functions and responsibilities of his or her position for 150 consecutive calendar days or 150 or more calendar days in any 365 consecutive calendar period.

Conditions to Receive Severance

In order to receive any benefits under this Plan, a Participant must sign a release agreement as a condition for severance benefits. The release agreement will provide the Company, its affiliates, and all officers, directors, employees and other representatives of the Company and its affiliates with a full release of any claims the Participant may have against them. In addition, the release agreement will have customary confidential requirements, non-compete/non-solicitation restrictions during the period a Participant is receiving severance payments (the “Restricted Period”), an acknowledgement of the Company’s ownership of intellectual property, and a requirement to return all Company property.

In order for the release agreement to be binding and effective, the Participant must sign the release agreement and return it to the Company within 21 days after he or she receives it and not have rescinded it within any applicable rescission period, which will generally be 7 days unless a longer period is required by law. The Company will endeavor to provide the Participant with the release agreement within 10 days after his or her termination of employment.

Administration

  

The Compensation Committee of the Board (the “Committee”) shall administer this Plan and shall delegate administration of the Plan to a designated Plan Administrator (“Plan Administrator”). The Plan Administrator shall be initially the Vice President, Human Resources, until such time as another Plan Administrator is designated by the Committee. In addition, the Plan Administrator shall make, in his or her reasonable discretion, all determinations arising in the administration, construction, or interpretation of the Plan, including the rights to construe disputed Plan terms and provisions. All such determinations shall be conclusive and binding on all persons, except as otherwise provided by law. The Plan Administrator is authorized to approve exceptions to this Plan, in his or her reasonable discretion, within the limits prescribed by Section 409A of the Internal Revenue Code and other applicable laws. This Plan is intended to constitute separation pay for purposes of Section 409A of the Internal Revenue Code and ERISA to the extent permissible and is otherwise intended to be a deferred compensation plan maintained primarily for a select group of management or highly compensated employees and to comply with section 409A of the Code, and shall be interpreted strictly in accordance with such foregoing intent. The Company reserves the right to decide whether the circumstances justify the payment of benefits under this Plan in any particular case, and the decision of the Company is final.

Claims Procedure

If a dispute arises between the Plan Administrator and a Participant or beneficiary over the amount of benefits payable under the Plan, the Participant or beneficiary may file a claim for benefits by notifying the Plan Administrator in writing of his or her claim. The Plan Administrator will review and adjudicate the claim. If the claimant and the Plan Administrator are unable to reach a mutually satisfactory resolution of the dispute, it will be submitted to arbitration under the rules of the American Arbitration Association. Each Participant agrees by continuing in his or her position which makes the Participant eligible to be a Participant, that arbitration will be the sole means of resolving disputes arising under the Plan and waives, on behalf of the Participant and any of his or her beneficiaries, any right to litigate any such dispute in a court of law.

Amendment & Termination

The Plan may be amended or terminated by the Company at any time for any reason, with or without notice. The Company reserves the right, by action of the Compensation Committee of the Board, or by any duly appointed successor committee or authorized delegate of the Board, to amend, modify, suspend or terminate this Plan and to disqualify employees from eligibility under the Plan at any time for any reason or for no reason with or without notice. Any such action is not contingent upon the financial condition of Mistras.
