CEO Change of Control Agreement and Change of Control Plan and

On March 17, 2026, the Compensation Committee (the “Committee”) of the Board of Directors of Oceaneering International, Inc. (the “Company”) approved an amendment and restatement of the Change of Control Agreement between the Company and Roderick A. Larson, the Company’s President and Chief Executive Officer (the “Amended CEO Change of Control Agreement”) and of the Company’s Change of Control Plan (the “Amended Change of Control Plan”).

The Amended CEO Change of Control Agreement modifies Mr. Larson’s prior Change of Control Agreement by conditioning Mr. Larson’s entitlement to the severance benefits payable under the agreement on his execution of a release of claims in favor of the Company and his compliance with restrictive covenants, including non-competition, non-solicitation, non-disparagement, confidentiality and cooperation, and by providing for outplacement services for 24 months.

The Amended Change of Control Plan modifies the prior Change of Control Plan by, among other things, providing for a prorated short‑term incentive award for the year of termination determined based on actual performance for such year (with any personal goals deemed met at target), payment of any earned but unpaid short‑term incentive award for the prior year, and outplacement services for 12 months.

The foregoing descriptions of the Amended CEO Change of Control Agreement and the Amended Change of Control Plan are general descriptions only and are qualified in their entirety by the full text of such agreement and plan, copies of which are attached as Exhibit 10.1 and Exhibit 10.2, respectively.

Executive Leadership Team Severance Plan

On March 17, 2026, the Committee also adopted the Oceaneering International, Inc. Executive Leadership Team Severance Plan (the “ELT Severance Plan”), which provides for severance benefits to eligible executives, including certain of the the Company’s named executive officers.

Under the ELT Severance Plan, if an executive’s employment is terminated by the Company without “Cause” or by the executive for “Good Reason” (as such terms are defined in the ELT Severance Plan), the executive will be entitled to the following severance benefits:

•An aggregate amount equal to one times (or two times, for the Chief Executive Officer) the sum of the executive’s base salary plus target short-term incentive opportunity, payable in equal installments over 12 months (or 24 months, for the Chief Executive Officer).

•A prorated short‑term incentive award for the year of termination, determined based on actual performance for such year (with any personal goals deemed met at target), and payment of any earned but unpaid short‑term incentive award for the prior year.

•For a period of 12 months (or 18 months, for the Chief Executive Officer), payment of the Company’s portion of the monthly premium for continued coverage under the Company’s medical, dental and vision plans, and continued participation in the Company’s supplemental executive health plan for executives (to the extent permitted by the plan).

•Prorated vesting of equity awards (for performance-based awards, to the extent that the performance goals are met based on performance for the full performance period).

•Outplacement services for 12 months (or 24 months, for the Chief Executive Officer).

These severance benefits are conditioned on the executive’s execution of a release of claims in favor of the Company and the executive’s compliance with restrictive covenants, including non-competition, non-solicitation, non-disparagement, confidentiality and cooperation.

No severance benefits are payable under the ELT Severance Plan to an executive whose employment is terminated by the Company without Cause or by the executive for Good Reason if, in connection with the termination, the executive is eligible for severance benefits under the Amended Change of Control Plan described below or an individual agreement.

The foregoing description of the ELT Severance Plan is a general description only and is qualified in its entirety by the full text of such plan, a copy of which is attached as Exhibit 10.3.

Re: Change of Control Agreement

Dear Rod:

Oceaneering International, Inc., a Delaware corporation (the “Company”), considers the establishment and maintenance of a sound and vital management to be essential for the protection and enhancement of the best interests of the Company and its shareholders. The Company recognizes that, as is the case with many publicly held corporations, the possibility of a “Change of Control” (as defined herein) may arise and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its shareholders. Accordingly, the Board of Directors of the Company (the “Board”) has determined that appropriate steps should be taken to assure the Company of the continuation of your service and to reinforce and encourage the attention and dedication of members of the Company’s management to their assigned duties without distraction in circumstances arising from the possibility of a Change of Control of the Company. In particular the Board believes it important, should the Company or its shareholders receive a proposal for or notice of transfer of control of the Company, or consider one itself, that you be able to assess and advise the Company whether such transfer would be or is in the best interests of the Company and its shareholders, and to take such other action regarding such transfer as the Board might determine to be appropriate without being influenced by the uncertainties of your own situation.

In order to induce you to remain in the employ of the Company, this letter agreement (this “Agreement”), prepared pursuant to authority granted by the Board, sets forth the compensation and severance benefits which the Company agrees will be provided to you should your employment with the Company be terminated in connection with a Change of Control under the circumstances described below, as well as certain other benefits which will be made available to you.

Reference is made to Annex I hereto for definitions of certain terms used in this Agreement, and such definitions are incorporated herein by such reference with the same effect as if set forth herein. Certain capitalized terms used in this Agreement in connection with the description of

515546225.4

Roderick A. Larson

March 17, 2026

Page 2

various Plans are defined in the respective Plans, but if any conflicts with a definition herein contained, this Agreement shall prevail.

1.Termination of Employment in Connection with a Change of Control.

(a)During the Effective Period, if there is a termination of your employment with the Company either by the Company without Cause or by you for Good Reason either (x) prior to the Effective Date, unless it is reasonably demonstrated by the Company that such termination of your employment (a) was not at the request of a third party who has taken steps reasonably calculated to effect the Change of Control and (b) otherwise did not arise in connection with or anticipation of the Change of Control or (y) on or after the Effective Date, and if such Effective Period commences during the life of this Agreement, you shall be entitled to the following benefits:

(i)all benefits conferred upon you by the Severance Package, and

(ii)in addition, all benefits payable under the provisions either of the Plans and Other Plans in which you are a participant immediately prior to the Effective Date, or of those plans in existence at the time of your Termination Date or pursuant to any other agreement between you and the Company, whichever are more favorable to you, in accordance with the terms and conditions of such Plans or Other Plans, such benefits to be paid under such Plans or Other Plans and not under this Agreement to the extent they are more favorable to you.

(b)You shall also be entitled to any such benefits if your termination results from your death or Disability if your death or Disability occurs:

(i)during the Effective Period but after the Effective Date, and

(ii)with respect to the benefits conferred by the Severance Package only, after either it has been decided that you will be terminated without Cause during the Effective Period, or you have given notice of termination for Good Reason during the Effective Period;

(c)You shall not be required to mitigate the amount of any payment provided for in this Agreement by seeking other employment, nor shall the amount of any payment provided for in this Agreement be reduced by any compensation earned by you as the result of employment by another Person after any Termination Date.

(d)Anything else in this Section 1 to the contrary notwithstanding, if (i) your employment is terminated in connection with a merger, consolidation or a tender offer or an exchange offer, (ii) you are entitled to the benefits provided for under the foregoing provisions of this Section 1 and (iii) your Termination Date

515546225.4	2

Roderick A. Larson

March 17, 2026

Page 3

precedes or occurs on the date of the closing of such merger, consolidation, tender offer or exchange offer, then unless otherwise agreed to by both parties in writing, all amounts to which you are or shall become entitled to under this Agreement, which are calculable as of the closing date, shall be accelerated to, and become immediately due and payable contemporaneously with such closing (or, if later, the Release Effective Date (as defined below).

(e)Notwithstanding anything in this Agreement to the contrary, your entitlement to the Severance Package is subject to the following requirements:

(i)You (or your estate, if applicable) must execute, deliver to the Company and not revoke a waiver and release of claims (a “Release”) substantially in the form attached hereto as Exhibit A hereto (subject to any modifications thereto as the Board reasonably determines are necessary to meet the requirements of applicable law) that becomes effective and irrevocable by no later than 60 days after the later of (A) the Termination Date and (B) the date that any of the events set forth under the definition of Change of Control shall have occurred (the date on which the Release becomes effective and irrevocable, the “Release Effective Date”).

(ii)You must comply with the restrictive covenants (the “Covenants”) set forth in Exhibit B hereto. In the event you fail to comply with any of the Covenants, you shall repay to the Company any portion of the Severance Package that you previously received, and no further portions of the the Severance Package shall be payable to you under this Agreement.

2.Procedures for Termination of Employment.

If your employment be terminated or intended to be terminated:

(a)For Cause, the Company shall transmit to you written notice setting forth the Cause for which you are proposed to be dismissed in sufficient detail to permit a reasonable assessment of the bona fides thereof, and setting a meeting of the Board not less than 30 days following the date of such notice at which the Board shall consider your termination and at which you and your counsel shall have the opportunity to be heard, following which the Board shall either by resolution withdraw the notice, or if it so finds in its good faith opinion, issue its report within 10 days thereafter that Cause exists and specifying the particulars of its findings, in which latter event a “final notice” shall occur. After receipt of a “final notice” of intended termination for Cause, you may contest such “final notice” in any court described in Section 4(b)(i) and all provisions of this Agreement, shall be continued until a Termination Date is determined pursuant to such contest. Within 10 days following the commencement of any such contest, the Company must escrow all amounts which would have been due pursuant to Section 1(a) if the “final notice” were not valid, at a bank of your choice (subject to applicable

515546225.4	3

Roderick A. Larson

March 17, 2026

Page 4

law and regulation). Should the result of the contest from which no further appeal is possible be that the:

(i)“final notice” is valid, then the Termination Date shall be the date no further appeal is possible;

(ii)“final notice” is not valid, then the Termination Date shall be the date no further appeal is possible.

(b)For Good Reason, you shall transmit to the Company written notice setting forth the Good Reason for which you propose to terminate your employment in sufficient detail to permit a reasonable assessment of the bona fides thereof. The Board shall issue a resolution to you not more than 10 days following the date of such notice as to either:

(i)Their Acceptance - In the event the Board accepts your notice of Good Reason, then the Termination Date is established and you are entitled to receive the amounts pursuant to Section 1(a); or

(ii)Their Rejection - In the event the Board rejects your notice of Good Reason, then (A) the Company must escrow within 10 days following the rejection the amounts which would have been due pursuant to Section 1(a) if your termination for Good Reason had been accepted, at a bank of your choice, (B) you must proceed to dispute resolution pursuant to Section 4, and (C) all provisions of this Agreement shall be continued until a termination is determined pursuant to such dispute resolution from which no further appeal is possible. The Termination Date shall be the date on which no further appeal is possible.

3.Excise Tax.

Notwithstanding anything in this Agreement to the contrary, if any amounts due to you under this Agreement and any other plan or program of the Company constitute a “parachute payment” as such term is defined in Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended (the “Code”), and the amount of the parachute payment, reduced by all federal, state and local taxes applicable thereto, including the excise tax imposed pursuant to Section 4999 of the Code, is less than the amount you would receive if you were paid three times your “base amount,” as defined in Section 280G(b)(3) of the Code, less $1.00, reduced by all federal, state and local taxes applicable thereto, then the aggregate of the amounts constituting the parachute payment shall be reduced to an amount that will equal three times your base amount less $1.00. This reduction in parachute payments will be taken only from (a) first, the cash payable under subsection (a) of the definition of Severance Package hereunder and (b) if further reduction is necessary, from performance awards (in chronological order beginning with the oldest) but only to the extent the value of such award for parachute payment purposes is equal to the economic value of such award. All determinations required to be made under this Section 3 shall be

515546225.4	4

made by the independent public accounting firm selected by the Company, subject to your consent which will not be unreasonably withheld, conditioned or delayed, and the fees and expenses of the accounting firm will be paid by the Company. The accounting firm shall provide detailed supporting calculations both to the Company and you. Absent manifest error, any determination by the accounting firm shall be binding upon the Company and you.

4.Dispute Resolution.

(a)This Agreement shall be governed in all respects, including as to validity, interpretation and effect, by the internal laws of the State of Texas without regard to any choice of law principles that would result in the application of the laws of another jurisdiction.

(b)It is irrevocably agreed that if any dispute arises with respect to any action, suit or other legal proceeding pertaining to this Agreement or to the interpretation of or enforcement of any of your rights under this Agreement:

(i)the Company and you agree that exclusive jurisdiction for any such suit, action or legal proceeding shall be in the state district courts of Texas sitting in Harris County, Texas;

(ii)the Company and you are each at the time present in Texas for the purpose of conferring personal jurisdiction;

(iii)the Company and you each consent to the jurisdiction of each such court in any such suit, action or legal proceeding and will comply with all requirements necessary to give such court jurisdiction;

(iv)the Company and you each waive any objection it may have to the laying of venue of any such suit, action or legal proceeding in any of such court;

(v)the Company and you each waive any objection or right to removal that may otherwise arise in any such suit, action or legal proceeding;

(vi)any such suit, action or legal proceeding may be brought in such court, and any objection that the Company or you may now or hereafter have to the venue of such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court is waived;

(vii)service of process in any such suit, action or legal proceeding may be effected by mailing a copy thereof by registered or certified mail, return receipt requested (or any substantially similar form of mail), postage prepaid, to such party at the address provided in Section 7 hereof; and

(viii)prior to any trial on the merits, the Company and you will submit to court supervised, non-binding mediation.

(c)Notwithstanding any contrary provision of Texas law, the Company shall have the burden of proof with respect to any of the following:

(i)that Cause existed at the time any notice was given to you under Section 2;

(ii)that Good Reason did not exist at the time notice was given to the Company under Section 2;

(iii)that the Company is not in default in performance of its obligations under this Agreement;

(iv)that the termination of your employment was not at the request of a third party who has taken steps reasonably calculated to effect the Change of Control and otherwise did not arise in connection with or anticipation of the Change of Control; and

(a)In the event any Successor does not assume this Agreement by operation of law, the Company will seek to have any Successor, by agreement in form and substance reasonably satisfactory to you, expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it. If there has been a Change of Control prior to, or a Change of Control will result from, any such succession, then failure of the Company to obtain at your request such agreement prior to or upon the effectiveness of any such succession (unless assumption occurs as a matter of law) shall constitute Good Reason for termination by you of your employment and, upon delivery of a notice of termination by you to the Company, you shall be entitled to the benefits provided for herein.

(b)This Agreement shall inure to the benefit of and be enforceable by your personal and legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

6.Fees and Expenses.

The Company shall reimburse you for all legal and other costs (including but not limited to, administrative, accounting, tax, human resource and expert witness fees and expenses) incurred by you as a result of your seeking to obtain, assert or enforce any right or benefit conferred upon you by this Agreement.

You shall submit all invoices for such costs to the Company no later than 30 days prior to the end of the taxable year following the taxable year in which they were incurred. The Company shall reimburse you for such costs within 14 days of receipt of such invoices.

No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement. This Agreement supersedes the Change of Control Agreement dated August 20, 2015 between the parties.

amounts will accrue interest and compound at the lesser of 2% per month or the highest interest rate allowed by applicable law.

12.Duplicate Originals.

This Agreement has been executed in duplicate originals, with one to be held by each of the parties hereto.

13.Section 409A.

(a)Notwithstanding anything in this Agreement to the contrary, if any provision of this Agreement would result in the imposition of an additional tax under Section 409A of the Code, that provision of this Agreement will be reformed to avoid imposition of the applicable tax and no action taken to comply with Section 409A of the Code shall be deemed to adversely affect your rights to the benefits provided by this Agreement. This Agreement is intended to comply with Section 409A of the Code, and ambiguous provisions hereof, if any, shall be construed and interpreted in a manner that is compliant with the application of Section 409A of the Code. The Agreement shall neither cause nor permit any payment, benefit or consideration to be substituted for a benefit that is payable under this Agreement if such action would result in the failure of any amount that is subject to Section 409A of the Code to comply with the applicable requirements of Section 409A of the Code. You shall have no right to specify the calendar year during which any payment hereunder shall be made.

(b)Notwithstanding any provision in this Agreement to the contrary, this Agreement shall not be amended or terminated in such manner that would cause this Agreement or any amounts or benefits payable hereunder to fail to comply with the requirements of Section 409A of the Code, to the extent applicable, and any such amendment or termination that may reasonably be expected to result in such non-compliance shall be of no force or effect.

(c)If you are a “Specified Employee” (as defined under Section 409A of the Code) as of the date of your “Separation from Service” (as defined under Section 409A of the Code) as determined by the Company, the payment of any amount under this Agreement on account of your Separation from Service that is deferred compensation subject to the provisions of Section 409A of the Code and not otherwise excluded from Section 409A of the Code, shall not be paid until the earlier of your death or the later of the first business day that is six months after the date after your Separation from Service or the date the payment is otherwise payable under this Agreement (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section (whether they would have otherwise been payable in a single sum or in installments in the

515546225.4	8

Roderick A. Larson

March 17, 2026

Page 9

absence of such delay) shall be paid or reimbursed to you in a lump sum, without interest, and any remaining payments due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

(d)All reimbursements or provision of in-kind benefits pursuant to this Agreement shall be made in accordance with Treasury Regulation §1.409A-3(i)(1)(iv) such that the reimbursement or provision will be deemed payable at a specified time or on a fixed schedule relative to a permissible payment event. Specifically, the amounts reimbursed or in-kind benefits provided under this Agreement during one taxable year may not affect the amounts reimbursed or provided in any other taxable year, the reimbursement of an eligible expense shall be made on or before the last day of the taxable year following the taxable year in which the expense was incurred, and the right to reimbursement or provision of an in-kind benefit is not subject to liquidation or exchange for another benefit. Notwithstanding any provision to the contrary in this Agreement, you agree that you shall submit reimbursable expenses to the Company no later than 30 days prior to the end of the taxable year following the taxable year in which they were incurred.

(e)An entitlement to a series of payments under this Agreement will be treated as an entitlement to a series of separate payments.

If this letter correctly sets forth our understanding with respect to the subject matter hereof, please sign and return one copy of this letter to the Company.

Sincerely,

OCEANEERING INTERNATIONAL, INC.

    Confidential Treatment.

other document filed in a lawsuit or other proceeding, if such filing is made under seal.

```
    Non-Competition; Non-Solicitation.
```

(a) You and the Company agree to the non-competition and non-solicitation provisions of this Section 6: (i) in consideration for the Proprietary Information provided by the Company to you; and (ii) to protect the Proprietary Information of the Company disclosed or entrusted to you by the Company or created or developed by you for the Company, the business goodwill of the Company developed through the efforts of you and the business opportunities disclosed or entrusted to you by the Company.

(b) Subject to the exceptions set forth in Section 6(c), you expressly covenant and agree that, during the Prohibited Period: (i) you will refrain from carrying on or engaging in, directly or indirectly, any Competing Business in the Restricted Area; and (ii) you will not, directly or indirectly, perform duties for, or provide services to, a Competing Business in the Restricted Area in any capacity that is the same as or substantially similar to the functions you performed for the Company during the preceding two years, or that would reasonably be expected to require use or disclosure of the Proprietary Information.

(c) Notwithstanding the restrictions contained in Section 6(b), you may own an aggregate of not more than 1% of the outstanding capital stock or other equity security of any class of any corporation or other entity engaged in a Competing Business, if such capital stock or other equity security is listed on a national securities exchange or regularly traded in the over-the-counter market by a member of a national securities exchange, without violating the provisions of Section 6(b), provided that you do not have the power, directly or indirectly, to control or direct the management or affairs of any such corporation or other entity and are not involved in the management of such corporation.

(d) You further expressly covenant and agree that, during the Prohibited Period, you will not: (i) engage or employ, or solicit or contact with a view to the engagement or employment of, any person who is an officer or employee of the Company; or (ii) canvass, solicit, approach or entice away or cause to be canvassed, solicited, approached or enticed away from the Company any person who or which is or was a customer of the Company, during the preceding two years, and, in each case, either (x) about which you received Proprietary Information or (y) with which you had contact or dealings on behalf of the Company.

(e) You expressly recognize that you are a key employee and an important member of the management or research and development team who will be provided with access to Proprietary Information and trade secrets as part of your employment and that the restrictive covenants set forth in this Exhibit B are reasonable and necessary in light of your position and access to the Proprietary Information.

515546225.4	B-3

    Non-Disparagement.  You agree that, following any termination of your employment with the Company, you will not make, publish, or communicate in any public forum or to the media any maliciously false, defamatory, or disparaging remarks, comments, or statements, whether orally or in writing, concerning the Company, the management of the Company, any product or service provided by the Company or the future prospects of the Company. Nothing in this paragraph is intended, or shall be interpreted, to restrict rights under Section 7 of the National Labor Relations Act, including rights to engage in concerted activities, or to preclude truthful testimony or filings with any Governmental Authority.

    Relief.  You and the Company agree and acknowledge that the limitations as to time, geographical area and scope of activity to be restrained as set forth in this Exhibit B are reasonable and do not impose any greater restraint than is necessary to protect the legitimate business interests of the Company. You and the Company also acknowledge that money damages would not be sufficient remedy for any breach of this Exhibit B by you, and the Company shall be entitled to enforce the provisions of this Exhibit B by terminating any portion of the Severance Package then owing to you under the Agreement or otherwise and to specific performance and injunctive relief as remedies for such breach or any threatened breach. Such remedies shall not be deemed the exclusive remedies for a breach of this Exhibit B but shall be in addition to all remedies available at law or in equity, including the recovery of damages from you and your agents. However, if it is determined that you have not committed a breach of this Exhibit B, then the Company shall resume payment of the Severance Package due under the Agreement and pay to you all portions of the Severance Package that had been suspended pending such determination.

    Reasonableness; Enforcement.  You acknowledge and agree that the geographic scope and duration of the covenants contained in this Exhibit B are fair and reasonable in light of: \(a\) the nature and wide geographic scope of the operations of the Business; \(b\) your level of control over and contact with the Business in all jurisdictions in which it is conducted; \(c\) the fact that the Business is conducted throughout the Restricted Area; and \(d\) the amount of compensation and Proprietary Information that you are receiving in connection with the performance of your duties for the Company. It is the desire and intent of you and the Company that the provisions of this Exhibit B be enforced to the fullest extent permitted under applicable Legal Requirements, whether now or hereafter in effect and, therefore, to the extent permitted by applicable Legal Requirements, you and the Company hereby waive the application of any provision of applicable Legal Requirements that would render any provision of this Exhibit B invalid or unenforceable, in whole or in part.

  Reformation.  The Company and you agree that the foregoing restrictions are reasonable under the circumstances and that any breach of the covenants contained in this Exhibit B would cause irreparable injury to the Company. You expressly represent that enforcement of the restrictive covenants set forth in this Exhibit B will not impose an undue hardship upon you or any Person affiliated with you. Further, you acknowledge that your skills are such that you can be gainfully employed in non-competitive employment, and that the restrictive covenants will not prevent you from earning a living. Nevertheless, if any of the aforesaid restrictions are found by a court of competent jurisdiction to be unreasonable, or overly broad as to geographic area or time, or otherwise unenforceable, the parties intend for the restrictions herein set forth to be modified by

515546225.4	B-4

the court making such determination so as to be reasonable and enforceable and, as so modified, to be fully enforced.

  Protected Disclosures.  Notwithstanding any provision to the contrary in the Agreement or this Exhibit B, nothing in the Agreement or this Exhibit B prohibits you from reporting possible violations of law or regulation to any governmental agency or entity, including the U.S. Department of Justice, the U.S. Securities and Exchange Commission, the U.S. Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation. Nothing in the Agreement or this Exhibit B limits your ability to communicate with any government agencies or otherwise participate in any investigation or proceeding that may be conducted by any government agency, including providing documents or other information, without notice to the Company. Additionally, you and the Company acknowledge and agree that you do not need the prior authorization of the Company to make any such reports or disclosures, and you are not required to notify the Company or any of its affiliates that you have made such reports or disclosures.

  Independence of Covenants.  The covenants contained in this Exhibit B shall operate independently from any similar covenants contained in any other individual agreement entered into between you and the Company.

(a)is a (i) Tier 1 Participant, (ii) Tier 2 Participant, (ii) Tier 3 Participant or (iv) Tier 4 Participant; and

3.2Change in Position and Cessation of Participant Status.

(a)A Participant shall cease to be a Participant if

515455016.3	6

(i)the Termination Date (A) does not occur during the Effective Period or (B) occurs during the Effective Period but for reasons other than those described in Section 4.2;

(ii)the Participant enters into an individual agreement with the Company providing for change‑of‑control benefits (other than one or more award agreements under one or more long-term incentive plans) after becoming a Participant, effective as the date of such individual agreement (and shall not be an Eligible Employee while such individual agreement is in effect); or

In such event, the Committee (or its delegate) shall notify the Employee of the change and, in its discretion, may require the Employee to execute a new Participant Agreement (with such new Participation Agreement replacing and superseding the Employee’s prior Participation Agreements).

ARTICLE IV

SEVERANCE BENEFITS

4.1Requirements for Severance Benefits. A Participant’s entitlement to the Severance Benefits is subject to the following requirements:

(a)Release. The Participant must execute, deliver to the Company and not revoke a waiver and release of claims (a “Release”) substantially in the form attached hereto as Exhibit B (subject to any modifications thereto as the Committee reasonably determines are necessary to meet the requirements of applicable law) that becomes effective and irrevocable by no later than 60 days after the later of (i) the Termination Date and (ii) the Change of Control Effective Date (the date on which the Release becomes effective and irrevocable, the “Release Effective Date”).

(b)Restrictive Covenants. The Participant must comply with the restrictive covenants (the “Covenants”) set forth in Annex A to the Participation Agreement. In the

515455016.3	7

event a Participant fails to comply with any of the Covenants, the Participant shall repay to the Company any Severance Benefits that the Participant previously received, and no further Severance Benefits shall be payable to the Participant under this Plan.

4.2Termination without Cause or for Good Reason. During the Effective Period, if a Participant’s employment is terminated by the Company without Cause or by the Participant for Good Reason either (a) prior to the Change of Control Effective Date, if (and only if) the Change of Control occurs, unless it is reasonably demonstrated by the Company that such termination of the Participant’s employment (i) was not at the request of a third party who has taken steps reasonably calculated to effect the Change of Control and (ii) otherwise did not arise in connection with, or in anticipation of, the Change of Control, or (b) on or after the Change of Control Effective Date, the Participant shall be entitled to the Severance Benefits, subject to the release requirement described in Section 4.1(a).

4.3Severance Benefits. For purposes of this Plan, with respect to a Participant, “Severance Benefits” shall mean and include the following:

(a)Severance Payment. A lump‑sum cash payment in an amount equal to the sum of (i) the applicable Severance Multiple for the Participant multiplied by the sum of the Participant’s (A) Base Salary, plus (B) Target Bonus, plus (ii) applicable COBRA Multiple, multiplied by (B) the Participant’s COBRA Premium. Such amount shall be paid to the Participant on the 60th day following the later of the Termination Date or the Change of Control Effective Date for the Change of Control giving rise to the payment of Severance Benefits to the Participant (which results due to the Termination Date occurring during the Effective Period).

(b)Prorated Short-Term Incentive. With respect to the short-term incentive that the Participant was eligible to earn for the year in which the Termination Date occurs, the Participant will receive payment of a prorated portion of such short-term incentive, in the amount, if any, determined based on actual performance for such year in accordance with the terms of the applicable Short-Term Incentive Award Program (provided that any performance goals that are based on individual performance of the Participant will be deemed met at target), with such proration calculated based on the number of days that the Participant was employed by the Company during such year, payable on the regular payment date under such plan.

(c)Health Plans. If the Participant is a Tier 1 Participant, Tier 2 Participant or Tier 3 Participant, continued eligibility during the 18-month period (the “Health Plan Period”) beginning on the later of (x) the Termination Date or (y) the date of the Change of Control giving rise to the payment of Severance Benefits (which results due to the Termination Date occurring during the Effective Period), for the Company’s medical, dental and vision benefit plans in which the Participant was entitled to participate immediately prior to the Termination Date at no greater monthly premium cost to the Participant than was paid by the Participant immediately prior to the Termination Date; provided, however, that the Participant’s continued participation is possible under the general terms and provisions of such plans. Notwithstanding the foregoing, (1) to the extent the coverage described above

515455016.3	8

cannot be provided under the Company’s benefit plans, or (2) if the Company’s obligations contemplated by clause (ii) of Section 4.3(a) would result in the imposition of excise taxes on the Company for failure to comply with the nondiscrimination requirements of the Patient Protection and Affordable Care Act of 2010, as amended, and the Health Care and Education Reconciliation Act of 2010, as amended (to the extent applicable), the Company shall discontinue such coverage, and, in either situation, during the Health Plan Period or remainder of the Health Plan Period, as applicable, the Participant shall be entitled to a monthly cash payment equal to the Company’s monthly portion of the premiums under such plans, determined as of the Termination Date. This Plan’s provision of continued participation in the Company’s medical, dental and vision plans is intended to satisfy the Company’s COBRA obligation, if any.

(d)Prior Year Short-Term Incentive. If the Termination Date occurs prior to the date on which the Participant receives payment of the short-term incentive, if any, earned by the Participant for the year prior to the year in which the Termination Date occurs, the Participant will receive payment of such short-term incentive, in the amount, if any, determined based on actual performance for such year in accordance with the terms of the applicable Short-Term Incentive Award Program, payable on the regular payment date under such plan; provided that if such regular payment date is prior to the Release Effective Date, then the Participant will receive such payment on the first regularly scheduled payroll date following the Release Effective Date.

(e)Outplacement. During the period beginning on the Release Effective Date and ending on the 12-month anniversary of the Termination Date, outplacement services will be made available to the Participant through a service provider selected by the Company; provided that the aggregate cost of such services will not exceed (i) $25,000 for a Tier 1 Participant or a Tier 2 Participant or (ii) $15,000 for a Tier 3 Participant or a Tier 4 Participant.

4.4No Mitigation through Subsequent Employment. No Participant shall be required to mitigate the amount of any payment provided for in this Plan by seeking other employment, nor shall the amount of any payment provided for in this Plan be reduced by any compensation earned by a Participant as the result of employment by another Person after the Termination Date.

4.5Code Section 280G. Anything in this Plan to the contrary notwithstanding, in the event it shall be determined that any payment or distribution in the nature of compensation (within the meaning of Code Section 280G(b)(2)) to or for the benefit of a Participant, whether paid or payable or distributed or distributable pursuant to the terms of this Plan or otherwise, but determined without regard to any reduction (if any) required under this Section 4.5 (the “Payment”), would be subject to the excise tax imposed by Code Section 4999, together with any interest or penalties imposed with respect to such excise tax (“Excise Tax”), then the Company shall automatically reduce (the “Reduction”) the Participant’s Payment to the minimum extent necessary to prevent the Payment (after the Reduction) from being subject to the Excise Tax, but only if, by reason of the Reduction, the after-tax benefit of the reduced

515455016.3	9

Payment exceeds the after-tax benefit if such Reduction was not made. If the after-tax benefit of the reduced Payment does not exceed the after-tax benefit if the Payment is not reduced, then the Reduction shall not apply. If the Reduction is applicable, the Payment shall be reduced in such a manner that provides the applicable Participant with the best economic benefit and, to the extent any portions of the Payment are economically equivalent with each other, each shall be reduced pro rata. All determinations to be made under this Section 4.5 shall be made by an independent public accounting firm selected by Oceaneering and the fees and expenses of the accounting firm will be paid by Oceaneering. The accounting firm shall provide detailed supporting calculations both to Oceaneering and any applicable Participant. Absent manifest error, any determination by the accounting firm shall be binding upon Oceaneering and any applicable Participant. In any event, the Company shall have no tax gross-up obligation or liability with respect to payment of a Participant’s excise tax liabilities under Section 4999 of the Code.

Notwithstanding the foregoing, no termination or amendment of this Plan or any Participation Agreement shall reduce or terminate a Participant’s right to receive, or continue to receive, any Severance Benefits that became payable in respect of a termination of the Participant’s employment that occurred prior to the date of such termination or amendment of this Plan or the Participation Agreement.

2.Definitions. As used in this Annex A, the following terms shall have the following meanings:

“Business” means any specific line of business, or any product or service offering, in which the Company is engaged during the Participant’s employment and as to which the Participant had responsibilities or received Proprietary Information.

“Competing Business” means any Person which, wholly or in any significant part, engages in any business competing with the Business in the Restricted Area.

___________________________________________

1 These restrictive covenants are subject to modification for any individual participant to the extent necessary to reflect local law requirements applicable to the participant.

515455016.3	A-3

“Restricted Area” means any state or, if outside the United States, any country or subdivision thereof in which the Company (i) is then currently engaged in the Business, (ii) has engaged in the Business during the preceding two years, or (iii) is actively pursuing business opportunities for the Business, and in each such case the Participant either (x) received Proprietary Information about the Company’s operations in such location or (y) worked for the Company in such location during the preceding two years.

3.Confidential Treatment. The Participant acknowledges and agrees that the Participant has acquired, and will in the future acquire as a result of the Participant’s employment by the Company or otherwise, Proprietary Information of the Company which is of a confidential or trade secret nature, and all of which has a great value to the Company and is a substantial basis and foundation upon which the Company’s business is predicated. Accordingly, other than in the legitimate performance of the Participant’s job duties, the Participant agrees:

(a)to regard and preserve as confidential at all times all Proprietary Information;

(b)to refrain from publishing or disclosing any part of the Proprietary Information and from using, copying or duplicating it in any way by any means whatsoever; and

(c)not to use on the Participant’s own behalf or on behalf of any third party or to disclose the Proprietary Information to any person or entity without the prior written consent of Oceaneering.

4.Property of the Company. The Participant acknowledges that all Proprietary Information and other property of the Company which the Participant accumulates during the Participant’s employment with the Company are the exclusive property of the Company. Upon the termination of the Participant’s employment with the Company, or at any time upon the Company’s request, the Participant shall surrender and deliver to the Company (and not keep, recreate or furnish to any third party) any and all work papers, reports, manuals, documents and the like (including all originals and copies thereof) in the Participant’s possession which contain Proprietary Information relating to the business, prospects or plans of the Company. Further, the Participant agrees to use reasonable efforts to search for and delete all Company information, including Proprietary Information, from the Participant’s computer, smartphone, tablet, or any other personal electronic storage devices (excluding, in each case, routine automatic backups that the Participant cannot reasonably access), other than payroll information or other financial information that the Participant may need for Participant’s tax filings, and, upon request, certify to the Company that the Participant has completed this search and deletion process.

5.Cooperation. The Participant agrees that, following any termination of the Participant’s employment with the Company, the Participant will not disclose, or cause to be disclosed, any Proprietary Information, unless (in any such case) required by court order. Pursuant to the Defend Trade Secrets Act of 2016, the Participant shall not be held criminally or civilly liable under any Federal or state trade secret law for the disclosure of any Proprietary Information that (i) is made (A) in confidence to a Federal, state or local government official,

515455016.3	A-4

either directly or indirectly, or to an attorney and (B) solely for the purpose of reporting or investigating a suspected violation of law or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. The Company may seek the assistance, cooperation or testimony of the Participant following any such termination in connection with any investigation, litigation or proceeding arising out of matters within the knowledge of the Participant and related to his or her employment by the Company, and in such instance, the Participant shall provide such assistance, cooperation or testimony and Oceaneering shall pay the Participant’s reasonable costs and expenses in connection therewith.

6.Non-Competition; Non-Solicitation.

(a)The Participant and Oceaneering agree to the non-competition and non-solicitation provisions of this Section 6: (i) in consideration for the Proprietary Information provided by the Company to the Participant; and (ii) to protect the Proprietary Information of the Company disclosed or entrusted to the Participant by the Company or created or developed by the Participant for the Company, the business goodwill of the Company developed through the efforts of the Participant and the business opportunities disclosed or entrusted to the Participant by the Company.

(b)Subject to the exceptions set forth in Section 6(c), the Participant expressly covenants and agrees that, during the Prohibited Period: (i) the Participant will refrain from carrying on or engaging in, directly or indirectly, any Competing Business in the Restricted Area; and (ii) the Participant will not, directly or indirectly, perform duties for, or provide services to, a Competing Business in the Restricted Area in any capacity that is the same as or substantially similar to the functions the Participant performed for the Company during the preceding two years, or that would reasonably be expected to require use or disclosure of the Proprietary Information.

(c)Notwithstanding the restrictions contained in Section 6(b), the Participant may own an aggregate of not more than 1% of the outstanding capital stock or other equity security of any class of any corporation or other entity engaged in a Competing Business, if such capital stock or other equity security is listed on a national securities exchange or regularly traded in the over-the-counter market by a member of a national securities exchange, without violating the provisions of Section 6(b), provided that the Participant does not have the power, directly or indirectly, to control or direct the management or affairs of any such corporation or other entity and is not involved in the management of such corporation.

(d)The Participant further expressly covenants and agrees that, during the Prohibited Period, the Participant will not: (i) engage or employ, or solicit or contact with a view to the engagement or employment of, any person who is an officer or employee of the Company; or (ii) canvass, solicit, approach or entice away or cause to be canvassed, solicited, approached or enticed away from the Company any person who or which is or was a customer of the Company, during the preceding two years, and, in each case, either (x) about which the Participant received Proprietary Information or (y) with which the Participant had contact or dealings on behalf of the Company.

515455016.3	A-5

(e)The Participant expressly recognizes that the Participant is a key employee and an important member of the management or research and development team who will be provided with access to Proprietary Information and trade secrets as part of the Participant’s employment and that the restrictive covenants set forth in this Annex A are reasonable and necessary in light of the Participant’s position and access to the Proprietary Information.

7.Non-Disparagement. The Participant agrees that, following any termination of the Participant’s employment with the Company, the Participant will not make, publish, or communicate in any public forum or to the media any maliciously false, defamatory, or disparaging remarks, comments, or statements, whether orally or in writing, concerning the Company, the management of the Company, any product or service provided by the Company or the future prospects of the Company. Nothing in this paragraph is intended, or shall be interpreted, to restrict rights under Section 7 of the National Labor Relations Act, including rights to engage in concerted activities, or to preclude truthful testimony or filings with any Governmental Authority.

8.Relief. The Participant and Oceaneering agree and acknowledge that the limitations as to time, geographical area and scope of activity to be restrained as set forth in this Annex A are reasonable and do not impose any greater restraint than is necessary to protect the legitimate business interests of the Company. The Participant and Oceaneering also acknowledge that money damages would not be sufficient remedy for any breach of this Annex A by the Participant, and the Company shall be entitled to enforce the provisions of this Annex A by terminating any Severance Benefits then owing to the Participant under the Plan or otherwise and to specific performance and injunctive relief as remedies for such breach or any threatened breach. Such remedies shall not be deemed the exclusive remedies for a breach of this Annex A A but shall be in addition to all remedies available at law or in equity, including the recovery of damages from the Participant and the Participant’s agents. However, if it is determined that the Participant has not committed a breach of this Annex A, then the Company shall resume the Severance Benefits due under the Plan and pay to the Participant all Severance Benefits that had been suspended pending such determination.

9.Reasonableness; Enforcement. The Participant acknowledges and agrees that the geographic scope and duration of the covenants contained in this Annex A are fair and reasonable in light of: (a) the nature and wide geographic scope of the operations of the Business; (b) the Participant’s level of control over and contact with the Business in all jurisdictions in which it is conducted; (c) the fact that the Business is conducted throughout the Restricted Area; and (d) the amount of compensation and Proprietary Information that the Participant is receiving in connection with the performance of the Participant’s duties for the Company. It is the desire and intent of the Participant and Oceaneering that the provisions of this Annex A be enforced to the fullest extent permitted under applicable Legal Requirements, whether now or hereafter in effect and, therefore, to the extent permitted by applicable Legal Requirements, the Participant and Oceaneering hereby waive the application of any provision of applicable Legal Requirements that would render any provision of this Annex A invalid or unenforceable, in whole or in part.

515455016.3	A-6

10. Reformation. The Company and the Participant agree that the foregoing restrictions are reasonable under the circumstances and that any breach of the covenants contained in this Annex A would cause irreparable injury to the Company. The Participant expressly represents that enforcement of the restrictive covenants set forth in this Annex A will not impose an undue hardship upon the Participant or any Person affiliated with the Participant. Further, the Participant acknowledges that the Participant’s skills are such that the Participant can be gainfully employed in non-competitive employment, and that the restrictive covenants will not prevent the Participant from earning a living. Nevertheless, if any of the aforesaid restrictions are found by a court of competent jurisdiction to be unreasonable, or overly broad as to geographic area or time, or otherwise unenforceable, the parties intend for the restrictions herein set forth to be modified by the court making such determination so as to be reasonable and enforceable and, as so modified, to be fully enforced.

11.Protected Disclosures. Notwithstanding any provision to the contrary in the Plan or this Annex A, nothing in the Plan or this Annex A prohibits the Participant from reporting possible violations of law or regulation to any governmental agency or entity, including the U.S. Department of Justice, the U.S. Securities and Exchange Commission, the U.S. Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation. Nothing in the Plan or this Annex A limits the Participant’s ability to communicate with any government agencies or otherwise participate in any investigation or proceeding that may be conducted by any government agency, including providing documents or other information, without notice to the Company. Additionally, the Participant and Oceaneering acknowledge and agree that the Participant does not need the prior authorization of the Company to make any such reports or disclosures, and the Participant is not required to notify the Company or any of its affiliates that the Participant has made such reports or disclosures.

12.Independence of Covenants. The covenants contained in this Annex A shall operate independently from any similar covenants contained in any other plan maintained by the Company in which the Participant participates or any individual agreement entered into between the Participant and the Company.

If a Participant’s employment is terminated by the Company without Cause or by the Participant for Good Reason, then subject to the requirements set forth in Section 3.2, the Participant shall be entitled to the following payments and benefits (collectively, the “Severance Benefits”):

(a)Base Salary and Target Short-Term Incentive Payments. The Participant will receive payments in an aggregate amount equal to the product of (i) one (or two, for the CEO), multiplied by (ii) the sum of the Base Salary plus the Target Short-Term Incentive, payable in substantially equal installments in accordance with the Company’s usual payroll practices during the period beginning on the Termination Date and ending on the 12-month anniversary of the Termination Date (or the 24-month anniversary of the Termination Date, for the CEO); provided that any such installments that would otherwise be payable prior to the Release Effective Date will be accumulated and paid on the first regularly scheduled payroll date following the Release Effective Date.

514904415.8	4

(c)Standard Health Plans. To the extent that, as of immediately prior to the Termination Date, the Participant and the Participant’s eligible dependents, if applicable, were covered under the Company’s medical, dental and vision plans (other than the supplemental health plan referenced in Section 3.1(d)), the Participant will receive payments in an aggregate amount equal to the Company’s portion of the monthly premium for such coverage the period beginning on the Termination Date and ending on the 12-month anniversary of the Termination Date (or the 18-month anniversary of the Termination Date, for the CEO), payable in substantially equal installments in accordance with the Company’s usual payroll practices during such period; provided that any such installments that would otherwise be payable prior to the Release Effective Date will be accumulated and paid on the first regularly scheduled payroll date following the Release Effective Date. For clarity, the Participant will not be required to elect to continue to participate in such plans under the Consolidated Omnibus Budget Reconciliation Act of 1985 to receive the payments described in this Section 3.1(c).

(d)Supplemental Executive Health Plan. If, as of immediately prior to the Termination Date, the Participant and the Participant’s eligible dependents, if applicable, were covered under the Company’s supplemental health plan for executives, if any, then to the extent permitted by the terms of such plan, the Participant will be entitled to elect to continue such coverage at the same cost to the Participant as for active senior executives, for the period beginning on the Termination Date and ending on the 12-month anniversary of the Termination Date (or the 18-month anniversary of the Termination Date, for the CEO).

(e)Time-Based Awards.

For clarity, the remaining portion of such Award will be forfeited as of the Termination Date.

(f)Performance-Based Awards. With respect to each unvested Award held by the Participant as of immediately prior to the Termination Date that was scheduled to vest based on achievement of specified performance goals for a performance period ending after the Termination Date, effective as of the Release Effective Date, a prorated portion of such Award will remain outstanding as of the last day of such performance period and will remain eligible to vest based on actual performance for such performance period, with such proration calculated based on the number of days that the Participant was employed by the Company during such performance period (and to the extent that such portion does not vest based on actual performance, such portion will be forfeited as of the last day of such performance period). For clarity, the remaining portion of such Award will be forfeited as of the Termination Date.

514904415.8	5

(b)Restrictive Covenants. The Participant must comply with the restrictive covenants (the “Covenants”) set forth in Annex A to the Participation Agreement. In the event a Participant fails to comply with any of the Covenants, the Participant shall repay to the Company any Severance Benefits that the Participant previously received, and no further Severance Benefits shall be payable to the Participant under this Plan.

3.3No Mitigation through Subsequent Employment. No Participant shall be required to mitigate the amount of any payment provided for in this Plan by seeking other employment, nor shall the amount of any payment provided for in this Plan be reduced by any compensation earned by a Participant as the result of employment by another Person after the Termination Date.

3.4No Duplication of Severance Benefits.

in written or electronic form of writings, correspondence, notes, drafts, records, maps, invoices, technical and business logs, policies, computer programs, disks or otherwise. Proprietary Information does not include information that is or becomes publicly known through lawful means.

“Restricted Area” means any state or, if outside the United States, any country or subdivision thereof in which the Company (i) is then currently engaged in the Business, (ii) has engaged in the Business during the preceding two years, or (iii) is actively pursuing business opportunities for the Business, and in each such case the Participant either (x) received Proprietary Information about the Company’s operations in such location or (y) worked for the Company in such location during the preceding two years.

    Confidential Treatment.  The Participant acknowledges and agrees that the Participant has acquired, and will in the future acquire as a result of the Participant’s employment by the Company or otherwise, Proprietary Information of the Company which is of a confidential or trade secret nature, and all of which has a great value to the Company and is a substantial basis and foundation upon which the Company’s business is predicated. Accordingly, other than in the legitimate performance of the Participant’s job duties, the Participant agrees:

(a) to regard and preserve as confidential at all times all Proprietary Information;

(b) to refrain from publishing or disclosing any part of the Proprietary Information and from using, copying or duplicating it in any way by any means whatsoever; and

(c) not to use on the Participant’s own behalf or on behalf of any third party or to disclose the Proprietary Information to any person or entity without the prior written consent of Oceaneering.

    Property of the Company.  The Participant acknowledges that all Proprietary Information and other property of the Company which the Participant accumulates during the Participant’s employment with the Company are the exclusive property of the Company. Upon the termination of the Participant’s employment with the Company, or at any time upon the Company’s request, the Participant shall surrender and deliver to the Company \(and not keep, recreate or furnish to any third party\) any and all work papers, reports, manuals, documents and the like \(including all originals and copies thereof\) in the Participant’s possession which contain Proprietary Information relating to the business, prospects or plans of the Company. Further, the Participant agrees to use reasonable efforts to search for and delete all Company information, including Proprietary Information, from the Participant’s computer, smartphone, tablet, or any other personal electronic storage devices \(excluding, in each case, routine automatic backups that the Participant cannot reasonably access\), other than payroll information or other financial information that the Participant may need for Participant’s tax filings, and, upon request, certify to the Company that the Participant has completed this search and deletion process.

514904415.8	A-2

    Cooperation.

The Company may seek the assistance, cooperation or testimony of the Participant following any such termination in connection with any investigation, litigation or proceeding arising out of matters within the knowledge of the Participant and related to his or her employment by the Company, and in such instance, the Participant shall provide such assistance, cooperation or testimony and Oceaneering shall pay the Participant’s reasonable costs and expenses in connection therewith.

```
    Non-Competition; Non-Solicitation.
```

(a) The Participant and Oceaneering agree to the non-competition and non-solicitation provisions of this Section 6: (i) in consideration for the Proprietary Information provided by the Company to the Participant; and (ii) to protect the Proprietary Information of the Company disclosed or entrusted to the Participant by the Company or created or developed by the Participant for the Company, the business goodwill of the Company developed through the efforts of the Participant and the business opportunities disclosed or entrusted to the Participant by the Company.

(b) Subject to the exceptions set forth in Section 6(c), the Participant expressly covenants and agrees that, during the [Prohibited Period] [Non-Compete Period]4: (i) the Participant will refrain from carrying on or engaging in, directly or indirectly, any Competing Business in the Restricted Area; and (ii) the Participant will not, directly or indirectly, perform duties for, or provide services to, a Competing Business in the Restricted Area in any capacity that is the same as or substantially similar to the functions the Participant performed for the Company during the preceding two years, or that would reasonably be expected to require use or disclosure of the Proprietary Information.

(c) Notwithstanding the restrictions contained in Section 6(b), the Participant may own an aggregate of not more than 1% of the outstanding capital stock or other equity security of any class of any corporation or other entity engaged in a Competing Business, if such capital stock or other equity security is listed on a national securities exchange or regularly traded in the over-the-counter market by a member of a national securities exchange, without violating the provisions of Section 6(b), provided that the Participant

514904415.8	A-3

does not have the power, directly or indirectly, to control or direct the management or affairs of any such corporation or other entity and is not involved in the management of such corporation.

(d) The Participant further expressly covenants and agrees that, during the [Prohibited Period] [Non-Solicit Period]5, the Participant will not: (i) engage or employ, or solicit or contact with a view to the engagement or employment of, any person who is an officer or employee of the Company; or (ii) canvass, solicit, approach or entice away or cause to be canvassed, solicited, approached or enticed away from the Company any person who or which is or was a customer of the Company, during the preceding two years, and, in each case, either (x) about which the Participant received Proprietary Information or (y) with which the Participant had contact or dealings on behalf of the Company.

(e) The Participant expressly recognizes that the Participant is a key employee and an important member of the management or research and development team who will be provided with access to Proprietary Information and trade secrets as part of the Participant’s employment and that the restrictive covenants set forth in this Annex A are reasonable and necessary in light of the Participant’s position and access to the Proprietary Information.

    Non-Disparagement.  The Participant agrees that, following any termination of the Participant’s employment with the Company, the Participant will not make, publish, or communicate in any public forum or to the media any maliciously false, defamatory, or disparaging remarks, comments, or statements, whether orally or in writing, concerning the Company, the management of the Company, any product or service provided by the Company or the future prospects of the Company. Nothing in this paragraph is intended, or shall be interpreted, to restrict rights under Section 7 of the National Labor Relations Act, including rights to engage in concerted activities, or to preclude truthful testimony or filings with any Governmental Authority.

    Relief.  The Participant and Oceaneering agree and acknowledge that the limitations as to time, geographical area and scope of activity to be restrained as set forth in this Annex A are reasonable and do not impose any greater restraint than is necessary to protect the legitimate business interests of the Company. The Participant and Oceaneering also acknowledge that money damages would not be sufficient remedy for any breach of this Annex A by the Participant, and the Company shall be entitled to enforce the provisions of this Annex A by terminating any Severance Benefits then owing to the Participant under the Plan or otherwise and to specific performance and injunctive relief as remedies for such breach or any threatened breach. Such remedies shall not be deemed the exclusive remedies for a breach of this Annex A A but shall be in addition to all remedies available at law or in equity, including the recovery of

___________________________________________

5 Insert “Prohibited Period” for the CEO and “Non-Solicit Period” for other participants.

514904415.8	A-4

damages from the Participant and the Participant’s agents. However, if it is determined that the Participant has not committed a breach of this Annex A, then the Company shall resume the Severance Benefits due under the Plan and pay to the Participant all Severance Benefits that had been suspended pending such determination.

    Reasonableness; Enforcement.  The Participant acknowledges and agrees that the geographic scope and duration of the covenants contained in this Annex A are fair and reasonable in light of: \(a\) the nature and wide geographic scope of the operations of the Business; \(b\) the Participant’s level of control over and contact with the Business in all jurisdictions in which it is conducted; \(c\) the fact that the Business is conducted throughout the Restricted Area; and \(d\) the amount of compensation and Proprietary Information that the Participant is receiving in connection with the performance of the Participant’s duties for the Company. It is the desire and intent of the Participant and Oceaneering that the provisions of this Annex A be enforced to the fullest extent permitted under applicable Legal Requirements, whether now or hereafter in effect and, therefore, to the extent permitted by applicable Legal Requirements, the Participant and Oceaneering hereby waive the application of any provision of applicable Legal Requirements that would render any provision of this Annex A invalid or unenforceable, in whole or in part.

  Reformation.  The Company and the Participant agree that the foregoing restrictions are reasonable under the circumstances and that any breach of the covenants contained in this Annex A would cause irreparable injury to the Company. The Participant expressly represents that enforcement of the restrictive covenants set forth in this Annex A will not impose an undue hardship upon the Participant or any Person affiliated with the Participant. Further, the Participant acknowledges that the Participant’s skills are such that the Participant can be gainfully employed in non-competitive employment, and that the restrictive covenants will not prevent the Participant from earning a living. Nevertheless, if any of the aforesaid restrictions are found by a court of competent jurisdiction to be unreasonable, or overly broad as to geographic area or time, or otherwise unenforceable, the parties intend for the restrictions herein set forth to be modified by the court making such determination so as to be reasonable and enforceable and, as so modified, to be fully enforced.

  Protected Disclosures.  Notwithstanding any provision to the contrary in the Plan or this Annex A, nothing in the Plan or this Annex A prohibits the Participant from reporting possible violations of law or regulation to any governmental agency or entity, including the U.S. Department of Justice, the U.S. Securities and Exchange Commission, the U.S. Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation. Nothing in the Plan or this Annex A limits the Participant’s ability to communicate with any government agencies or otherwise participate in any investigation or proceeding that may be conducted by any government agency, including providing documents or other information, without notice to the Company. Additionally, the Participant and Oceaneering acknowledge and agree that the Participant does not need the prior authorization of the Company to make any such reports or disclosures, and the Participant is not required to notify the Company or any of its affiliates that the Participant has made such reports or disclosures.

514904415.8	A-5

  Independence of Covenants.  The covenants contained in this Annex A shall operate independently from any similar covenants contained in the Change of Control Plan or any individual agreement entered into between the Participant and the Company.

514904415.8	A-6
