CHANGE IN CONTROL
                                    AGREEMENT

THIS AGREEMENT is made as of the 14th day of March, 2005 by and between
McDermott International, Inc., a corporation duly organized under the laws of
the Republic of Panama (the "Company") and John T. Nesser III ("Executive".)

In consideration of the mutual covenants and agreements contained herein, and
other good and valuable consideration, the receipt and sufficiency of which are
hereby expressly acknowledged, the parties hereto agree as follows:

I.    Obligations of the Company Upon Termination of Executive After Change In
      Control. Following the Effective Date of a Change In Control, in the event
      Executive's employment by the Company is terminated before the one-year
      anniversary of the Effective Date of a Change In Control either (i) by the
      Company for any reason other than Cause, or (ii) by the Executive for Good
      Reason, then subject to the provisions of paragraph (b) below, the Company
      shall:

            (a)   Pay to the Executive within thirty days after the date of
                  termination of Executive's employment (or such earlier time as
                  may be required by law) the Accrued Benefits;

            (b)   In the event that a bonus is paid after the date of
                  Executive's termination of employment under the Company's
                  Executive Incentive Compensation Plan ("EICP") for the year
                  prior to the year in which the termination takes place (the
                  "Measurement Period"), pay to the Executive in a lump sum, at
                  the same time such bonus is paid to other EICP participants, a
                  cash bonus equal to the product of the multiplier used for
                  Executive Vice Presidents and Executive's annual base salary
                  for the Measurement Period.


            (c)   Pay to Executive in a lump sum in cash within thirty days
                  after the date of termination of Executives employment a
                  payment equal to the product of Executive's target bonus under
                  EICP for the year in which the termination takes place and a
                  fraction, the numerator of which is the number of days that
                  have elapsed in the year in which the termination takes place
                  through the date of termination of Executive's employment and
                  the denominator of which is 365.

            (d)   Pay to Executive in a lump sum in cash as soon as
                  administratively practicable after the date of termination of
                  Executive's employment 200% of the sum of (1) Executive's
                  annual base salary as in effect immediately prior to the date
                  of termination of Executive's employment, and (2) Executive's
                  target bonus under EICP for the year in which the termination
                  takes place.

            (e)   In the event that it is determined that any payment or
                  distribution of any type to or for the benefit of the
                  Executive made by the Company, by any of its affiliates, by
                  any person who acquires ownership or effective control or
                  ownership of a substantial portion of the Company's assets
                  (within the meaning of section 280G of the Internal Revenue
                  Code of 1986, as amended, and the regulations thereunder (the
                  "Code")) or by any affiliate of such person, whether paid or
                  payable or distributed or distributable pursuant to the terms
                  of this Agreement or otherwise (the "Total Payments") would be
                  subject to the excise tax imposed by Section 4999 of the Code
                  (the "Excise Tax"), then the Executive shall be entitled to
                  receive an additional payment (an "Excise Tax Restoration
                  Payment") in an amount that shall fund the payment by the
                  Executive of any Excise Tax on the Total Payments as well as
                  all income taxes imposed on the Excise Tax Restoration
                  Payment, and any Excise Tax imposed on the Excise Tax
                  Restoration Payment.

                                        2


II.   Participation In Other Company Programs.

      Nothing in this Agreement shall prevent or limit Executive's continuing or
      future participation in any plan, program, policy or practice provided by
      the Company for which Executive may qualify, nor, subject to paragraph (d)
      of Section X, shall anything herein limit or otherwise affect such rights
      as Executive may have under any contract or agreement with the Company.
      Amounts which are vested benefits or which Executive is otherwise entitled
      to receive under any plan, policy, practice or program of or any contract
      or agreement with the Company at or subsequent to the date of termination
      of Executive's employment shall be payable in accordance with such plan,
      policy, practice or program or contract or agreement except as explicitly
      modified by this Agreement. Notwithstanding the foregoing, it is expressly
      understood and acknowledged by Executive that any payment by the Company
      under Section I hereof shall be in lieu of any obligation on the part of
      the Company for payment of severance benefits under the Severance Plan for
      Employees of McDermott Incorporated and Participating Subsidiary and
      Affiliated Companies or any successor thereto or any other plan, policy or
      agreement of the Company in the event of termination of Executive's
      employment as provided in Section I hereof with the Company during the
      one-year period following the Effective Date of a Change In Control.

III.  Confidential and Proprietary Information.

      Executive acknowledges and agrees that any and all non-public information
      regarding the Company, any of its Subsidiaries and its or their customers
      (including but not limited to any and all information relating to its or
      their business practices, products, services, finances, management,
      strategy, profits and overhead) is confidential and the unauthorized
      disclosure of such confidential information will result in irreparable
      harm to the Company. Executive shall not, during his employment by the
      Company or any of its Subsidiaries and for a period of five years after
      termination of such employment (or such shorter period as may be required
      by law), disclose or permit the

                                       3


      disclosure of any such confidential information to any person other than
      an employee of the Company or its Subsidiaries or an individual engaged by
      the Company or its Subsidiaries to render professional services to the
      Company or its Subsidiaries under circumstances that require such person
      to maintain the confidentiality of such information, except as such
      disclosure may be required by law. The provisions of this Section III
      shall survive any termination of this Agreement. For purposes of this
      Section III, the term "confidential information" shall not include
      information that was or becomes generally available to the public other
      than as a result of disclosure by Executive. Executive acknowledges that
      the execution of this Agreement and the payments described in Section I
      herein constitute consideration for the limitations on activities set
      forth in this Section III, the adequacy of which is hereby expressly
      acknowledged by Executive. Executive understands and agrees that the
      Company shall suffer irreparable harm if Executive breaches Section III
      hereof, and that monetary damages shall be inadequate to address any such
      breach. Accordingly, Executive agrees that the Company shall have the
      right, to the extent permitted by applicable law, and in addition to any
      other rights or remedies it may have, to obtain from any court of
      competent jurisdiction, injunctive relief to restrain any breach or
      threatened breach hereof or otherwise to specifically enforce the
      provisions hereof.

                  is delivered to Executive by the Compensation Committee of the
                  Board or the Chief Executive Officer of the Company which

            (3/4) of the entire membership of the Compensation Committee of the
            Board at a meeting of such Committee called and held for such
            purpose (after reasonable notice is provided to Executive and
            Executive is given an opportunity, together with counsel, to be
            heard before the Compensation Committee of the Board), finding that,
            in the good faith opinion of the Compensation Committee of the

                  other than the Company or any employee benefit plan sponsored
                  by the Company, becomes the "beneficial owner" (as such term
                  is used in Section 13 of the Exchange Act) of 25 percent or
                  more of the total number of the Company's common shares at the
                  time outstanding; or

                                       11


            (ii)  of the approval by the vote of the Company's stockholders

                  least a majority of the directors then still in office who
                  were directors at the beginning of such period.

            A Change In Control shall not result from any transaction
            precipitated by the Company's insolvency, appointment of a
            conservator or determination by a regulatory agency that the Company
            is insolvent.

      (e)   "Disability" shall mean circumstances that qualify Executive for
            long-term disability benefits under the Company's Long-Term

            paragraph (d)(i) above; (ii) the effective date of the consummation
            of a merger, consolidation, share exchange or similar form of

                                       12


            Date of a Change In Control, the Board of Directors or its designee
            shall, within thirty days thereof, provide written notice to
            Executive of the Effective Date of the Change In Control.
            Notwithstanding anything to the contrary in this Agreement, if a
            Change In Control occurs and if Executive's employment with the
            Company is terminated within the ninety days prior to the Effective
            Date of the Change In Control as determined in accordance with the
            first sentence of this paragraph (f), and if it is reasonably
            demonstrated by Executive that such termination of employment was at
            the request of a third party who has taken steps reasonably
            calculated to effect a Change In Control, or otherwise arose in
            connection with or in anticipation of a Change In Control, then for
            all purposes of this Agreement, the "Effective Date" of the Change
            In Control shall mean the date immediately prior to the date of such
            termination of employment.

      (g)   "Good Reason" shall mean:

            (i)   the assignment to Executive of duties that are materially
                  inconsistent with Executive's position, authority, duties or
                  responsibilities immediately prior to the Change In Control,
                  or any other action by the Company which results in a material
                  diminution in such position, authority, duties or
                  responsibilities;

            (ii)  requiring Executive, without his consent, to be based at any
                  office or location other than the office or location a which
                  Executive was employed immediately prior to the Change In
                  Control; provided, however, that any such relocation requests
                  shall not be grounds for resignation with Good Reason if such
                  relocation is within a twenty-mile radius of the location at
                  which Executive was based prior to the Effective Date of a
                  Change In Control;

                                       13


            (iii) a reduction in Executive's Annual Base Salary in effect
                  immediately prior to the Change In Control or a reduction in
                  the target multiplier used to calculate the annual bonus
                  awarded to Executive below the target multiplier used to
                  calculate the bonus paid to Executive under the EICP
                  immediately prior to the Change In Control, provided, however
                  that in either case a reduction in the Annual Base Salary or
                  the target bonus multiplier shall not be considered "Good
                  Reason" with respect to any year for which such reduction is
                  part of a reduction uniformly applicable to all similarly
                  situated employees;

            (iv)  a change in Executive's eligibility to participate in
                  incentive compensation plans as in effect immediately prior to
                  the Change In Control; or

            (v)   any material breach of this Agreement by the Company,
                  excluding for this purpose an isolated, insubstantial or
                  inadvertent action not taken in bad faith and which is
                  remedied by the Company promptly after receipt of notice
                  thereof given by Executive.

            Upon the occurrence of any of the events described above, Executive
            shall give the Company written notice that such event constitutes
            Good Reason and the Company shall thereafter have thirty days in
            which to cure. If the Company has not cured in that time, the event
            shall constitute Good Reason.

      (h)   "Subsidiaries" shall mean every, limited liability company,
            partnership or other entity of which 50% or more of the total
            combined voting power of all classes of voting securities or other
            equity interests is owned, directly or indirectly, by McDermott
            International, Inc.
