Vesting Dates:

1.Award. In accordance with the Mistras Group, Inc. 2016 Long-Term Incentive
Plan (the “Plan”), Mistras Group, Inc. (the “Company”) has made an award to you
of restricted stock units (the “RSUs”). Each RSU, upon vesting, will become one
share of the Company’s common stock. The award and the RSUs are subject to the
provisions of the Plan and, to the extent not prohibited by the Plan, the terms
and conditions of this certificate. Capitalized terms that are used but not
defined in this certificate shall have the meanings ascribed to them by the
Plan.

2.Vesting of RSUs. Except as otherwise provided herein or the Plan, the RSUs
will vest in equal annual installments on each of the dates set forth above, or
100% on the vesting date if only one vesting date is listed above. All vesting
is subject to your continuous employment or other service with the Company or a
Subsidiary from the Grant Date until the applicable vesting date, except as
otherwise provided in this certificate or in the Plan.

3.Termination of Employment; Forfeiture of Unvested RSUs. Unless the Committee,
acting in its sole and absolute discretion, determines otherwise, upon the
termination of your employment and other service with the Company and its
Subsidiaries (“Termination of Employment”), you will forfeit all right, title
and interest in the unvested RSUs, unless your Termination of Employment is as a
result of (i) Retirement, in which case the terms of Section 4 shall control,
(ii) death or permanent disability, in which case Section 5 shall control, or
(iii) as expressly set forth in the Plan, such as in connection with a Change of
Control.

4.Eligible Retirement. (a) The following terms shall govern if you retire
pursuant to an Eligible Retirement. As used in this Section 4, “Eligible
Retirement” means that you have reached the age of 65. If you meet the Eligible
Retirement terms, and you retire or resign from providing service to the Company
and its subsidiaries, you will be a “Retiree.” If you are a Retiree, any
outstanding unvested RSUs hereunder shall continue to vest after retirement but
only on the condition that you continuously comply with the restrictive
covenants set forth below in (b).

(b) In consideration of you having the benefit of post-retirement vesting of
RSUs upon becoming a Retiree, you agree that continuously until 6 months after
the last of the any unvested RSUs you may have vests (such period being the
“Restricted Period”), you shall not, directly or indirectly, on your own behalf
or on behalf of any person other than the Company (i) engage in, have an equity
or profit interest in, or lend money to, or manage, operate, or work for any
person, firm, corporation, partnership, or business (whether as a director,
officer, employee, agent, representative, partner, security holder, consultant,
or otherwise) that engages in any business which competes in any respect with
the Company or any of its Subsidiaries, or (ii) recruit or otherwise solicit or
induce any employee, consultant, customer, client, or supplier of the Company or
any of its Subsidiaries to (A) terminate its employment or other business
arrangement or relationship with the Company or any of its Subsidiaries, (B)
otherwise change its relationship with the Company or any of its Subsidiaries or
(C) establish any business relationship with you or person controlled by or
related to you for any business

purpose competitive with the Company or of its Subsidiaries. A passive
investment by you in a publicly traded company in which you exercise no
operational or strategic control and which constitutes less than 2% of the
outstanding shares of such entity shall not constitute a breach of this
covenant.

(c) If you fail to meet the restrictive covenants set forth in (b) above
continuously during the Restricted Period, then (i) all unvested RSUs shall
automatically be cancelled and forfeited, and (ii) you shall repay to the
Company the value realized by you of all post retirement vesting of RSUs without
any reduction for taxes paid by or withheld on your behalf on account of any
such value realized.

5.Vesting Upon Death or Disability. Upon your Disability (as defined in the
Plan) or death, all unvested RSUs shall vest and, in the case of your death, the
shares represented by such RSUs shall be distributed to your heirs.

6.Transfer Restrictions. You may not sell, assign, transfer, pledge, hedge,
hypothecate, encumber or dispose of in any way (whether by operation of law or
otherwise) any unvested RSUs, and unvested RSUs shall not be subject to
execution, attachment or similar process. Any attempt by you or any other person
claiming against, through or under you to cause unvested RSUs to be transferred
or assigned in any manner and for any purpose not permitted hereunder or under
the Plan shall be null and void and without effect upon the Company, you or any
other person.

7.No Ownership of Stock; No Dividends or Voting Rights. The RSUs do not
represent shares of the Company’s common stock, and no dividends or other
distributions will be payable on unvested RSUs, and you will not have any voting
rights with respect to the unvested RSUs.

8.Issuance of Shares Upon Vesting. If, as and when any RSU becomes vested, and
subject to the satisfaction of applicable withholding and other legal
requirements, the vested RSU becomes void and you shall own one share of common
stock of the Company for each vested RSU.

9.Withholding. The vesting of RSUs covered by this certificate shall be subject
to and conditioned upon the satisfaction by you of applicable tax withholding
obligations. The Company and its Subsidiaries may require you to remit an amount
sufficient to satisfy applicable withholding taxes or deduct or withhold such
amount from any payments otherwise owed to you. By accepting this award, you
expressly authorizes the Company to deduct from any compensation or any other
payment of any kind due to you, including withholding shares issued in exchange
for vested RSUs, for the amount of any federal, state, local or foreign taxes
required by law to be withheld in connection with the vesting of RSUs; provided,
however, that the value of the RSUs withheld may not exceed the statutory
maximum withholding amount allowed by law.

10.Provisions of the Plan and the Committee’s Authority Control. This
certificate is subject to all the terms, conditions and provisions of the Plan
and to the rules, regulations and interpretations as may be established or made
by the Committee acting within the scope of its authority and responsibility
under the Plan. A copy of the Plan is available to you and may be obtained from
the Company’s Corporate Secretary at the Company’s corporate headquarters. The
applicable provisions of the Plan shall govern in any situation where this
certificate is silent or where the applicable provisions of this certificate are
contrary to or not reconcilable with such Plan provisions. The Committee shall
have complete discretion in the exercise of its rights, powers, and duties with
respect to the award represented by this certificate. Any interpretation or
construction of any provision of, and the determination of any question arising
under, this certificate shall be made by the Committee in its discretion and

Company or its Subsidiaries or to increase, decrease or otherwise adjust your
compensation and any other terms and conditions of your employment or other
service.

of, any successor or successors of the Company, you and any of your
beneficiaries.
