McDermott International, Inc. Retention Restricted Stock Award Grant Agreement

EXHIBIT 10.3

McDermott International, Inc.

Retention Restricted Stock Award Grant Agreement

This Retention Restricted Stock Award Grant Agreement (this “Agreement”) is made and entered into by and between McDermott International, Inc., a Panamanian corporation (“McDermott” or the “Company”), and David Dickson, an individual and employee of the Company (“Grantee”), as of the 31st day of October, 2013 (the “Date of Grant”). The shares of Restricted Stock granted to Grantee pursuant to this Agreement are not being granted under the 2009 McDermott International, Inc. Long-Term Incentive Plan, as it may be amended from time to time hereafter (the “Plan”), but are subject to the terms and conditions as would be applicable if they had been granted under the Plan, except for Sections 4.1 and 4.2 of the Plan. Accordingly, the terms and conditions of the Plan are hereby incorporated herein by this reference and shall apply to this grant of Restricted Stock as if such grant was granted pursuant to the terms of the Plan, except to the extent that this Agreement expressly provides to the contrary. All determinations and interpretations made by the Committee with regard to any question arising hereunder shall be binding and conclusive on you and your beneficiaries, estate or personal representatives. Capitalized terms not otherwise defined in this Agreement shall have the respective meanings given to them in the Plan.

The term “Company,” as used in this Agreement with reference to employment or service, shall include subsidiaries of McDermott. Whenever the words “you” or “your” are used in any provision of this Agreement under circumstances where the provision should logically be construed to apply to any beneficiary, estate, or personal representative to whom any rights under this Agreement may be transferred by will or by the laws of descent and distribution, they shall be deemed to include any such person or estate. This Agreement shall be subject to the Company’s Clawback Policy, which is attached hereto as Exhibit A and is incorporated herein by reference.

The Compensation Committee of the Board of Directors (the “Committee”) of McDermott has awarded you a grant of Restricted Stock (“Restricted Stock”) on the Date of Grant

Restricted Stock Award

Restricted Stock Award. You have been awarded a grant of Restricted Stock. This grant represents a right to be issued 537,482 shares of McDermott common stock on the Date of Grant, subject to the restrictions contained in this Agreement. Shares evidencing the Restricted Stock will be issued in your name as of the Date of Grant.

Restrictions. Unless and until the vesting requirements and other terms set forth in this Agreement have been satisfied, the Restricted Stock may not be sold, transferred, pledged, assigned or otherwise alienated (the “Restrictions”).

Vesting Requirements. Subject to the “Forfeiture of Restricted Stock” paragraph below, the Restricted Stock will become vested under one or more of the following circumstances (each such date a “Vesting Date”):

Upon vesting, the Restrictions with respect to the shares of Restricted Stock will be removed as soon as administratively practicable.

Forfeiture of Restricted Stock. Shares of Restricted Stock which are not and do not become vested upon your termination of employment with the Company for any reason shall, coincident therewith, be forfeited and be deemed to no longer be outstanding.

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 shares of Restricted Stock 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 such matters.

Voting Rights and Dividends. Beginning on the Date of Grant and subject to the forfeiture provisions of this Agreement, you will have full voting rights and will be credited with cash dividends, if any, with respect to the Restricted Stock granted hereunder.

Taxes

You will realize income in connection with this grant of Restricted Stock in accordance with the tax laws of the jurisdictions applicable to you. You should consult your tax advisor as to the U.S. federal income tax consequences associated with this Restricted Stock as it relates to your specific circumstances. McDermott, however, has been advised that the grant awarded hereunder will have the following tax consequences under the present U.S. Federal tax laws and regulations.

For U.S. federal income tax purposes, you will be deemed to have received compensation taxable as ordinary income equal to the fair market value, as of the date of vesting, of the shares of Restricted Stock which vest. Such income will be included in your taxable income and reported on IRS Form W-2 in the tax year in which the shares vest. Alternatively, you may elect to have the fair market value of the shares included in your taxable income and reported on IRS Form W-2 as of the Date of Grant.

In addition, all dividends paid, if any, to you with respect to unvested shares of Restricted Stock will be considered wages paid to you by your employer and, therefore, will be included in your taxable income and reported on IRS Form W-2 in the year in which such shares vest.

By acceptance of this Agreement, you agree that any amount which the Company is required to withhold on your behalf, including state income tax and FICA withholding, in connection with income realized by you under this Agreement will be satisfied by withholding whole shares having an aggregate fair market value as equal in value but not exceeding the amount of such required tax withholding, unless the Committee determines to satisfy the statutory minimum withholding obligation by another method permitted by the Plan.

Regardless of the withholding method referred to above, you are liable to the Company for the amount of income tax 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, 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

The shares of Restricted Stock 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 before the end of the second (2^nd) business day following the Date of Grant. 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, fax or telephone if you intend to reject this grant. Absent such notice of rejection, the Company will prepare and file the required Form 4 on your behalf within the required two (2) business-day deadline.

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 entering this Agreement, nor any provision of this Agreement or the Plan, nor any action taken by the Company, your employer, the Committee or the Board of Directors under the Plan, 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 (“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.

In witness whereof, this Agreement is hereby approved and executed as of the date first written above.
