Restricted Stock Units

RSU Award. You have been awarded the number of RSUs shown on the Notice of Grant dated February 27, 2019, which is incorporated herein by reference (this “Award”). Each RSU represents a right to receive the value of one Share on the Vesting Date (as set forth in the “Vesting Requirements” paragraph below), provided the vesting requirements set forth in this Agreement shall have been satisfied. No Shares or cash amounts are awarded or issued to you hereunder on the Date of Grant.

Vesting Requirements. Subject to the “Forfeiture of RSUs” paragraph below, RSUs do not provide you with any rights or interest therein until they become vested under one or more of the following circumstances (each such date a “Vesting Date”):

1

For purposes of this Agreement, a “Reduction in Force” shall mean a termination of employment with the Company due to elimination of a previously required position or previously required services, or due to the consolidation of departments, abandonment of facilities or offices, technological change or declining business activities, where such termination is intended to be permanent; or under other circumstances which the Committee, in accordance with standards uniformly applied with respect to similarly situated employees, designates as a reduction in force.

For purposes of this Agreement “Cause” means: (i) your continued failure to perform substantially your duties with the Company (occasioned by reason other than your physical or mental illness, death or disability) after a written demand for substantial performance is delivered to you by the Committee which specifically identifies the manner in which the Committee or the Chief Executive Officer believes that you have not substantially performed your duties, after which you shall have 30 days to defend or remedy such failure to substantially perform your duties; (ii) the engaging by you in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Company; or (iii) your conviction of, with no further possibility of appeal for, or plea of guilty or nolo contendere by you to, any felony. The cessation of your employment under items (i) and (ii) of this paragraph shall not be deemed to be for “Cause” unless and until there shall have been delivered to you a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters (3/4) of the entire membership of the Committee at a meeting of the Committee called and held for such purpose (after reasonable notice is provided to you and you are given an opportunity, together with counsel, to be heard before the Committee), finding that, in the good faith opinion of the Committee, you are guilty of the conduct described in items (i) or (ii) of this paragraph, and specifying the particulars thereof in detail.

For purposes of this Agreement “Good Reason” means any one or more of the following events which occurs following a Change in Control: (a) a material diminution in your duties or responsibilities of from those applicable immediately before the date on which a Change in Control occurs; (b) a material reduction in your annual salary as in effect on the Effective Date of this Agreement or as the same may be increased from time to time; (c) the failure by the Company to continue in effect any compensation plan in which you participate immediately before the Change in Control which is material to your total compensation, unless a comparable arrangement (embodied in an ongoing substitute or alternative plan) has been made with respect to such plan, or the failure by the Company to continue your participation therein (or in such substitute or alternative plan) on a basis not materially less favorable than existed immediately before the Change in Control, unless the action by the Company applies to all similarly situated employees; (d) the failure by the Company to continue to provide you with material benefits in the aggregate that are substantially similar to those enjoyed by you under any of the Company’s pension, savings, life insurance, medical, health and accident, or disability plans in which you were participating immediately before the Change in Control if such benefits are material to your total compensation, the taking of any other action by the Company which would directly or indirectly materially reduce any of such benefits or deprive you of any fringe benefit enjoyed by you at the time of the Change in Control if such fringe benefit is material to your total compensation, unless the action by the Company applies to all similarly situated employees; or (e) a change in the location of your principal place of employment with the Company by more than 50 miles from the location where you were principally employed immediately before the Change in Control without your consent. If a Change in Control occurs and any of the events described above occurs prior to the third anniversary of such Change in Control (an “Event”), you shall give McDermott written notice (the “Notice”) within 60 days following your knowledge of an Event that you intend to terminate employment as a result. McDermott shall have 30 days following receipt of the Notice in which to cure the Event. If McDermott does not take such action within that time, the Event shall constitute Good Reason. If you do not provide the Notice within 60 days as required above then the Event shall not constitute Good Reason, and thereafter, for purposes of determining whether you have Good Reason, your terms and conditions of employment after the occurrence of the Event shall be substituted for those terms and conditions of your employment in effect immediately prior to the date of this Agreement.

Forfeiture of RSUs. RSUs which are not and do not become vested upon your termination of employment with the Company for any reason shall, coincident therewith, terminate and be of no further force or effect.

In the event that, while you are employed by the Company or are performing services for or on behalf of the Company under any consulting agreement, (a) you are convicted of (i) a felony or (ii) a misdemeanor involving fraud, dishonesty or moral turpitude, or (b) you engage in conduct that adversely affects or may reasonably be expected to adversely affect the business reputation or economic interests of the Company, as determined in the sole judgment of the Committee, then all RSUs and all rights or benefits awarded to you under this Agreement shall be forfeited, terminated and withdrawn immediately upon (1) notice to the Committee of such conviction pursuant to (a) above or (2) final determination pursuant to (b) above by the Committee. The Committee shall have the right to suspend any and all rights or benefits awarded to you hereunder pending its investigation and final determination with regard to any such matters.

Payment of RSUs. In the sole discretion of the Committee, RSUs shall be paid in (i) Shares, (ii) cash equal to the Fair Market Value of the Shares otherwise deliverable on the Vesting Date, or (iii) any combination thereof, which shall be distributed or paid as soon as administratively practicable, but in any event no later than 30 days, after the applicable Vesting Date.

Taxes

You will realize income in connection with this Award in accordance with the tax laws of the jurisdictions applicable to you. You are solely responsible for the taxes associated with the RSUs, and you should consult with and rely on your own tax advisor, accountant or legal advisor as to the tax consequences to you of this grant.

By acceptance of this Agreement, you agree that any amount which the Company withholds on your behalf, including PAYE, federal or state income tax and employee national insurance contributions or FICA withholding, or pursuant to applicable Company policy, in connection with income realized by you under this Agreement will be satisfied by withholding cash or whole Shares having an aggregate Fair Market Value equal to but not exceeding the amount (as determined by the Company) of such tax withholding, unless the Committee determines to cause the withholding obligation to be satisfied by another method permitted by the Plan. If you are a non-U.S. based taxpayer, the amount which the Company will withhold will be determined based on the tax laws of the jurisdiction applicable to you or applicable Company policy as determined on each applicable Vesting Date. If you are a U.S. based taxpayer, the amount which the Company will withhold is set forth below, with your grade level for purposes of this Agreement determined on each applicable Vesting Date:

In each case above, the withholding amounts above are in addition to employment taxes (FICA and Medicare) as well as any applicable state withholding taxes that may be due. The Committee may, in its discretion, require or allow withholding of cash or Shares for taxes on a different basis than described above, on such terms and conditions as it may determine.

Regardless of the withholding method referred to above, you are liable to the Company for the amount of income tax and employee national insurance contributions or FICA withholding which the Company is required to withhold in connection with the income realized by you in connection with this Agreement, and you hereby authorize the Company to withhold such amount (as determined by the Company), in whole or in part, from subsequent salary payments, without further notice to you, if the withholding method referred to above is not utilized or does not completely cover such required tax withholding.

Transferability

RSUs granted hereunder are non-transferable other than by will or by the laws of descent and distribution or pursuant to a qualified domestic relations order.

Securities and Exchange Commission Requirements

If you are a Section 16 insider, this type of transaction must be reported on a Form 4. Please be aware that if you intend to reject the grant, you should do so immediately after the Date of Grant to avoid potential Section 16 liability. Please advise Dennis Edge and Kim Wolford immediately by e-mail or telephone if you intend to reject this grant. Absent such notice of rejection, the Company intends to prepare and file the required Form 4 on your behalf (pursuant to your standing authorization for us to do so).

If you are currently subject to these requirements, you will have already been advised of your status. If you become a Section 16 insider at some future date, reporting will be required in the same manner noted above.

Other Information

Neither the action of the Company in establishing the Plan, nor any provision of the Plan, nor any action taken by the Company, your employer, the Committee or the Board of Directors under the Plan, nor any provision of this Agreement shall be construed as giving to you the right to be retained in the employ of the Company or any of its subsidiaries or affiliates.

This Award is intended to comply with or be exempt from Section 409A of the Internal Revenue Code of 1986, as amended, and in its implementing regulations (“Section 409A”), and ambiguous provisions, if any, shall be construed in a manner that is compliant with or exempt from the application of Section 409A, as appropriate. Notwithstanding any provision of this Award to the contrary, if you are a “specified employee” within the meaning of Section 409A as of the date of your termination of employment and the Company determines, in good faith, that immediate payments of any amounts or benefits would cause a violation of Section 409A, then any amounts or benefits which are payable under this Award upon your “separation from service” within the meaning of Section 409A which (i) are subject to the provisions of Section 409A; (ii) are not otherwise excluded under Section 409A; and (iii) would otherwise be payable during the first six-month period following such separation from service shall be paid on the first business day next following the earlier of (1) the date that is six months and one day following the date of termination or (2) the date of the participant’s death.
