WHEREAS, the Employee currently serves the Company as its President and Chief Executive Officer and has tendered his voluntary resignation; and

WHEREAS, in connection with the Employee's resignation, the Employee and the Company desire to enter into a mutually satisfactory arrangement concerning, among other matters, the Company's offer of severance benefits to the Employee in exchange for certain post-employment covenants by the Employee and the Employee's general release of claims against the Company and related parties.

NOW, THEREFORE, in consideration of the promises and mutual covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which are mutually acknowledged, the Employee and the Company hereby agree as follows:

1.Resignation. The Employee's resignation as President and Chief Executive Officer of the Company, and from each other position he held as an employee, officer, director, committee member, or other service provider of the Company or any of its affiliates or subsidiaries or joint ventures (collectively, the "Company Group"), is effective as of October 15, 2017 (the "Termination Date"), and the Employee shall not represent himself after the Termination Date as continuing to be an employee,

officer, director, agent, or representative of the Company or any other member of the Company Group for any purpose. The Termination Date shall be the date of Employee's separation from service for purposes of participation in and coverage under all benefit plans and programs sponsored by or through the Company Group, except as otherwise provided herein or under the terms of such plans or as required by applicable law.

Accrued Obligations and Severance Benefits.

(a)Accrued Obligations. As soon as practicable following the Termination Date (but in no event later than such date required by applicable law or the terms of the applicable Company benefit plan), regardless of whether this Agreement becomes effective, the Employee will be paid or provided

(i)all accrued but unpaid base salary and reimbursable-but-unreimbursed business expenses through and including the Termination Date, if any, (ii) all unused vacation time earned and accrued by the Employee through and including the Termination Date pursuant to the Company's vacation policy, which totals

Supplemental Executive Retirement Plan, as amended (the "SERP"), paid in accordance with the terms and conditions of the SERP based on service through and including the Termination Date (the "SERP Benefits''.), and (v) all other benefits payable to the Employee upon a separation from service under the Company's benefit plans (other than severance benefits), in accordance with the terms of such plans, or as required by applicable law. For the avoidance of doubt, the Employee shall not be required to repay to the Company any amounts paid to him under the Incentive Bonus Agreement, entered into by

Doc#: US1;11623167v9

and between the Company and the Employee, dated as of December 15, 2016 (the "Bonus Agreement"), that the Employee would otherwise be required to repay as a result of the Employee's voluntary termination of employment with the Company prior to the first anniversary of the date thereof.

applicable, are required to pay for such participation from time to time. For the avoidance of doubt, the benefits provided to the Employee under Section 2 of this Agreement shall not be considered "compensation" for purposes of calculating the SERP Benefits.

(c)Legal Fees. The Company will pay the Employee's legal counsel directly, upon presentation of customary invoices, for the fees and expenses incurred by the Employee in connection with the review and negotiation of this Agreement, up to a maximum of Forty Thousand Dollars ($40,000).

Accordingly, for and in consideration of the Severance Benefits, the Employee agrees as follows:

(a)Noncompetition. During the two (2) year period following the Employee's separation from service with the Company (the "Restricted Period"), the Employee agrees that he shall not engage in competitive activities within any jurisdiction specified in Appendix A so long as the Company Group carries on a like line of business therein (collectively, the "Restricted Area"), as follows:

(i)The Employee shall not, directly or indirectly, for himself or others or in association with any other person, own, manage, operate, control, be employed in an executive,
managerial, or supervisory capacity by, or otherwise engage or participate in, or allow his skill, knowledge, experience, or reputation to be used in connection with, the ownership, management,
operation, or control of any company or other business enterprise engaged in the Restricted Business within the Restricted Area; provided, however, that nothing contained herein shall prohibit the Employee from (A) holding as a passive investment less than 1% of the equity interests of a publicly traded business enterprise engaged in the Restricted Business within any of the Restricted Area, or (B) serving as an outside director on the boards of directors of Exploration & Production (E&P), Oilfield Services (OFS) or other companies that are not in direct competition with the Company.

(ii)The Employee shall not, directly or indirectly, for himself or others or in association with any other person, solicit any customer of the Restricted Business or of the Company, or otherwise interfere, induce, or attempt to induce any customer, supplier, licensee, or business relation of
the Company Group for the purpose of soliciting, diverting, interfering, or enticing away the business of such customer, supplier, licensee, or business relation, or otherwise disrupting any previously established relationship existing between such customer, supplier, licensee, or business relation and the Company
Group.

(b)Nonsolicitation. During the Restricted Period, the Employee agrees that he shall not, directly or indirectly, for himself or others or in association with any other person, make contact with any of the employees or independent contractors of the Company Group for the purpose of soliciting such employee or independent contractor for hire, whether as an employee or independent contractor, or for the purpose of inducing such person to leave the employ of the Company Group or reduce the level of services provided by such person to the Company Group, or otherwise to disrupt the relationship of such person with the Company Group. In addition, during the Restricted Period, the Employee shall not hire, on behalf of himself or any company engaged in the Restricted Business, any employee of the Company Group, whether or not such engagement is solicited by the Employee.

(c)Nondisclosure of Confidential Information. The Employee shall hold in a fiduciary capacity and for the benefit of the Company Group all Confidential Information that shall have been obtained by the Employee during his employment. At all times following his separation from service, the Employee agrees (a) not to communicate or make available to any person or entity (other than a member of

the Company Group) any such Confidential Information, except upon the prior written authorization of the Board or as may be required by law or legal process, and (b) to deliver promptly to the Company upon its written request any Confidential Information in his possession. In the event that the provisions of any applicable law or the order of any court would require the Employee to disclose or otherwise make available any Confidential Information to a governmental authority or to any other third party, the Employee shall give the Company, unless it is unlawful to do so, prompt prior written notice of such required disclosure and, if possible given the terms of any production order of the judicial governmental or administrative body, an opportunity to contest the requirement of such disclosure or apply for a protective order with respect to such Confidential Information by appropriate proceedings. Notwithstanding the foregoing, the Employee understands that nothing contained in this Agreement limits his ability to communicate with any federal, state, or local governmental agency or commission (a "Government Agency") or otherwise participate in any investigation or proceeding conducted by any Government Agency, without notice to the Company, or to receive an award for information provided to any Government Agency.

(d)Nondisparagement and Response to Inquiries. The Employee hereby agrees not to defame, disparage, or criticize any of the Company Releasees or any of their products, services, finances, financial condition, capabilities, or other aspect of any of their businesses in any medium to any person or entity, without limitation in time. Notwithstanding this provision, the Employee may confer in

confidence with his legal representative and make truthful statements as required by law. Following the termination of the Employee's employment with the Company, the Company agrees to direct its directors to not disparage the Employee or the Employee's performance or otherwise make any statement that is critical of the Employee's personal or professional reputation. Each director on the Board agrees not to defame, disparage or criticize the Employee in any medium to any person or entity, without limitation in time. Notwithstanding this provision, any such director may confer in confidence with his legal representatives and make truthful statements as required by law. The Company shall respond to inquiries from third parties concerning Employee's employment with and separation from the Company by stating only his title and dates of employment.

(e)Remedies and Injunctive Relief. The Employee acknowledges that a violation by the Employee of any of the covenants contained in this Section 8 would cause irreparable damage to the Company Group in an amount that would be material but not readily ascertainable, and that any remedy at law (including the payment of damages) would be inadequate. Accordingly, the Employee agrees that, notwithstanding any provision of this Agreement to the contrary, the Company Group shall be entitled (without the necessity of showing economic loss or other actual damage) to seek injunctive relief (including temporary restraining orders, preliminary injunctions, and permanent injunctions) in any court of competent jurisdiction for any actual or threatened breach of any of the covenants set forth in this Section 8 in addition to any other legal or equitable remedies it may have. The preceding sentence shall not be construed as a waiver of the rights that the Company Group may have for damages under this Agreement or otherwise, and all of the Company Group's rights shall be unrestricted.

(f)

Among those risks and uncertainties, many of which are beyond the control of the Company, including, without limitation, the effects on the market price of the Company's common stock and on the Company's ability to access the capital markets; volatility in worldwide energy demand and oil and gas prices, and continuing depressed levels of oil and gas prices, without a clear indication of if, or when, prices will recover to a

level to support renewed offshore exploration activities; consolidation of our customer base; fleet additions by competitors and industry overcapacity; our views with respect to the need for and timing of the replenishment of our asset base, including through acquisitions or vessel construction; changes in capital spending by customers in the energy industry for offshore exploration, field development and production; loss of a major customer; changing customer demands for vessel specifications, which may make some of our older vessels technologically obsolete for certain customer projects or in certain markets; delays and other problems associated with vessel construction and maintenance; uncertainty of global financial market conditions and difficulty in accessing credit or capital; potential difficulty in meeting financial covenants in material debt or other obligations of the Company or in obtaining covenant relief from lenders or other contract parties; acts of terrorism and piracy; integration of acquired businesses and entry into new lines of business; disagreements with our joint venture partners; significant weather conditions; unsettled political conditions, war, civil unrest and governmental actions, such as expropriation or enforcement of customs or other laws that are not well developed or consistently enforced, or requirements that services provided locally be paid in local currency, in each case especially in higher political risk countries where we operate; foreign currency fluctuations; labor changes proposed by international conventions; increased regulatory burdens and oversight; changes in laws governing the taxation of foreign source income; retention of skilled workers; enforcement of laws related to the environment, labor and foreign corrupt practices; and the resolution of pending legal proceedings.
