     average.  Such  three  (3)  Fiscal  Years  need  not  be  consecutive.  The
     Participant's  average monthly rate of  Compensation  will be determined by
     dividing  the total  Compensation  attributable  to such  three (3)  Fiscal
     Years, as determined in accordance with rules established by the Committee,
     by the number of full or  partial  months of the  Participant's  employment
     during  such  three  (3)  Fiscal  Years.  Compensation  attributable  to  a
     particular  Fiscal Year shall not include  base salary  earned (or Variable

               shall be equal to such payments when and as they are made; or

               program(s) maintained by any other previous employer.

          However,  if any such Participant shall have contributed to the source

          retirement  income  to  which  he  would  have  been  entitled  on his
          Retirement Date, computed as for retirement in accordance with Section
          2.1  hereof,  as if his  employment  had not been  terminated  but had
          continued  uninterrupted from the date of disability to his Retirement
          Date and as if his  Compensation  for the one year period prior to his
          disability had continued  without  change to his Retirement  Date. The

          (1)  if the  Participant  recovers  from his  disability  prior to his
               Retirement  Date,  the last payment shall be the payment due next
               preceding the date of such recovery; or

          (2)  if the  Participant  attains  his  Retirement  Date  while  still
               disabled, the last payment will be the payment next preceding the

               been married to the  Participant on his Retirement Date and shall
               have survived him, for her lifetime.

     (C)  Benefit Payable in the Event of Death of Disabled:

          Participant  prior to Retirement Date: If a disabled  Participant dies
          prior to his Retirement  Date, his surviving  spouse shall be entitled
          to receive for her  remaining  lifetime a monthly  income equal to the
          monthly  retirement  income to which the  Participant  would have been
          entitled  under Section 2.1 if he had retired on his  Retirement  Date
          and  if  his  Compensation  for  the  one  year  period  prior  to his
          disability  had  continued  without  change  to his  Retirement  Date;
          provided, however, that on the deceased Participant's Retirement Date,
          the amount of monthly income payable to his surviving  spouse shall be
          reduced to one-half of said monthly income.

     (D)  (1)  Benefits  on  Termination  of  Service:   In  the  event  that  a
          Participant  who has  attained  age 60 on or before  December 31, 1993
          terminates  employment on or after December 31, 1993 for reasons other
          than his death disability or retirement  under Section 2.2 hereof.  he
          shall be entitled to receive a monthly retirement income as determined
          in  accordance  with the  applicable  provision of Section 2.1 hereof,
          based upon the  Participant's  Number of Years of Credited Service and
          Final Average Monthly Compensation as determined on December 31, 1993.
          The monthly  retirement  payment under this  paragraph will be payable
          commencing on the  Participant's  Retirement Date as determined  under
          Section 1.1(14)  hereof,  and the last payment will be the payment due
          next preceding the terminated  Participant's death, provided,  however
          that  following  a  terminated  Participant's  death,  one-half of the
          retired  Participant's  monthly retirement income shall be paid to his


                                       17


          spouse if she shall have been married to the  Participant  on the date
          his monthly  retirement  payments  commenced,  and shall have survived
          him, for her lifetime.  If a Participant  should die after termination
          of employment and before monthly  retirement income payments commence,
          no benefits whatsoever shall be payable under this Plan.

          (2)  Except as to those Participants described in paragraph (1) above,
               in the event that a  Participant  terminates  employment  for any
               reason  other  than his death,  disability  or  retirement  under
               Section 2.2 hereof, he, and his spouse,  shall not be entitled to
               any benefits whatsoever under this Plan.

          (3)  Notwithstanding any other provision of this Plan to the contrary,
               in the event a  Participant's  employment is  terminated  for any
               reason  whatsoever  after  the  date of an  Effective  Change  in
               Control but prior to his Retirement  Date,  such  Participant (or
               his surviving  spouse, if any) shall be vested in and entitled to
               receive the greater of (i) the benefits to which such Participant
               or surviving spouse may be entitled to under any other provisions
               of this Plan, or (ii) the Deferred Vested Benefit provided below.
               The Deferred  Vested  Benefit with respect to such a  Participant
               shall be a non forfeitable  benefit determined in accordance with
               Section 2.1 hereof based on such Participant's Number of Years of
               Credited   Service  and  Final   Average   Monthly   Compensation
               determined of the date of the Effective Change in Control;


                                       18


               provided,  however,  that  the  amount  of such  Deferred  Vested
               Benefit  payable to a Participant who is employed by any Employer
               other  than  J.  Ray  McDermott   S.A.  and  its  Subsidiary  and
               Affiliated Companies (prior to giving effect to the Participant's
               Monthly Retirement Plan Offset) shall not be less than 21% of the
               Participant's Final Average Monthly Compensation determined as of
               the date of his termination of employment.  The benefits  payable
               to a Participant under this subparagraph (3) shall be paid in the
               form of a lump sum distribution equal to the present value of the
               monthly income amounts that would otherwise be received under the
               Plan,  commencing as of the Participant's  date of termination of
               employment.

               The  amount  of  such  lump  sum  distribution  to be paid to any
               Participant shall be calculated using the following assumptions:

               (a)  The mortality  table based on the prevailing  commissioners'
                    standard  table  (described in Section  807(d)(5)(A)  of the
                    Code) used to determine reserves for group annuity contracts
                    issued on the date as of which  present  value is determined
                    (without  regard  to  any  other   subparagraph  of  Section
                    807(d)(5)   of  the  Code)   that  is   prescribed   by  the
                    Commissioner of Internal Revenue in revenue rulings, notices
                    or  other  guidance   published  in  the  Internal   Revenue
                    Bulletin; and


                                       19


               (b)  The annual rate of interest on 30-year  Treasury  securities
                    as  specified  by the  Commissioner  of Internal  Revenue in
                    revenue rulings,  notices or other guidance published in the
                    Internal   Revenue   Bulletin   for  the   month  of  August
                    immediately  preceding  the  first  day of the Plan  Year in
                    which  the   Participant's   Retirement  Date  occurs.   The
                    applicable interest rate shall be determined annually.

               Payment  hereunder  shall be made within  thirty (30) days of the
               date  of  the  Participant's  termination  of  employment.  If  a
               Participant should die after terminating employment with a vested
               right   hereunder  and  prior  to  the  payment  of  a  lump  sum
               distribution, such distribution shall be payable to his surviving
               spouse,  if any,  at the  time it  would  have  been  paid to the
               Participant,  if such  spouse  shall  have  been  married  to the
               Participant  on  the  date  he  terminated  employment  with  the
               Employer.

2.5  INCREASE IN BENEFITS

     In the event a Participant,  or his surviving spouse, is receiving benefits
     under  Sections  2.1, 2.2 or 2.4 (A) through (C) hereof and the  Retirement
     Plan for Employees of McDermott  Incorporated and Subsidiary and Affiliated
     Companies  provides for an increase in pension payments after retirement as
     a result  of cost of  living  or  similar  adjustments,  then the  benefits
     payable  under  Sections  2.1,  2.2 or 2.4 (A) through (C) hereof  shall be
     similarly  increased  based  upon  the  same  cost  of  living  or  similar
     adjustments as set forth in such retirement plan.


                                       20


2.6  LUMP SUM ELECTION

     Notwithstanding  anything to the  contrary  which may be  contained  in the
     Plan, a Participant  retiring under Section 2.1 or 2.2 after  attaining the
     age of 60 or terminating  employment  with a vested  interest under Section
     2.4(D)(1) shall have the right, with the consent of the Committee, to elect
     a lump sum  distribution  equal to the present value of the monthly  income
     amounts that would  otherwise be received  under the Plan. If a Participant
     retires at age 65, such  Participant  must have  requested,  in writing the
     consent of the  Committee to make such election at least twelve (12) months
     but not more than  eighteen  (18) months prior to such  Participant's  65th
     birthday.  If a  Participant  should die after  reaching  age 60 and before
     retiring, the spouse shall also have the right, with the written consent of
     the Committee, to elect a lump sum distribution.

     The amount of the lump sum distribution to be paid to any Participant shall
     be calculated using the following criteria:

     (A)  The form of benefit (e.g.,  joint and 50% survivor)  shall be the same
          as that  elected by the  Participant  under the ERISA  qualified  plan
          applicable to the Participant;

     (B)  The mortality  table based on the prevailing  commissioners'  standard
          table  (described  in  Section  807(d)(5)(A)  of  the  Code)  used  to
          determine  reserves for group annuity  contracts issued on the date as


                                       21


          of which  present  value is  determined  (without  regard to any other
          subparagraph  of Section  807(d)(5) of the Code) that is prescribed by
          the Commissioner of Internal  Revenue in revenue  rulings,  notices or
          other guidance published in the Internal Revenue Bulletin; and

     (C)  The  annual  rate  of  interest  on  30-year  Treasury  securities  as
          specified by the  Commissioner of Internal Revenue in revenue rulings,
          notices or other guidance  published in the Internal  Revenue Bulletin
          for the month of  August  immediately  preceding  the first day of the
          Plan Year in which  the  Participant's  Retirement  Date  occurs.  The
          applicable   interest  rate  shall  be  determined   annually  Payment
          hereunder  shall  be  made  within  thirty  days  of the  date  of the
          Participant's retirement;  provided,  however that if the payment of a
          lump sum  distribution  hereunder would cause the Applicable  Employee
          Remuneration (as defined in Section  162(m)(4) of the Internal Revenue
          Code of  1986,  as  amended)  to  exceed  the  limitation  of  Section
          162(m)(1) of the Code,  then in its sole  discretion the Committee may
          defer such payment.  Deferred  payment  hereunder shall be made within
          thirty days of the first day of the fiscal year of the  Employer  next
          following the Participant's retirement date.

          A  deferred  lump  sum  distribution  shall  earn  interest  from  the
          Participant's date of retirement until paid,  compounded daily, at the
          minimum  commercial  lending  rate charged from time to time by Morgan
          Guaranty  Trust  Company of New York for loans in New York City.  If a
          Participant  should die after  retiring  and prior to the payment of a


                                       22


          deferred lump sum distribution,  such distribution shall be payable to
          his spouse at the time it would have been paid to the Participant,  if
          she shall have been  married to him on his  Retirement  Date and shall
          have survived him. Any payment made under this Section 2.6 shall be in
          complete  satisfaction  of  any  amounts  which  may  be  due  to  any
          Participant or his surviving spouse or any other person claiming under
          either of them pursuant to any other provisions of the Plan."

                                   SECTION 3

                SPECIAL PROVISIONS REGARDING PAYMENT OF BENEFITS

3.1  BENEFITS APPLICABLE TO PARTICIPANT WHO HAS BEEN OR IS EMPLOYED BY TWO OR
     MORE EMPLOYERS

     In the event that a  Participant  or his  surviving  spouse is  entitled to
     benefits under the Plan and such Participant has been or is employed by any
     two or more Employers, his retirement benefit shall be computed by applying
     the  benefit  formulas  as if all the  Employers  were a  single  Employer,
     provided  there is a proper  allocation  (taking  into account the Credited
     Service and  Compensation  applicable to each Employer) of the costs of the
     resulting  benefits among the Employers by which such  Participant has been
     or is employed.

3.2  PARTICIPANTS TO FURNISH REQUIRED INFORMATION

     Each  Participant  will furnish to the Committee  such  information  as the
     Committee  considers  necessary or desirable for purposes of  administering
     the Plan, and the provisions of the Plan respecting any payments thereunder
     are conditional upon the Participant's  furnishing promptly such true, full
     and complete information as the Committee may request.


                                       23


     Each Participant will submit proof of his age to the Committee at such time
     as required by the Committee.  The Committee  will, if such proof of age is
     not  submitted  as  required,  use as  conclusive  evidence  thereof,  such
     information as is deemed by it to be reliable,  regardless of the source of
     such information. Any adjustment required by reason of lack of proof or the
     misstatement of the age of persons entitled to benefits  hereunder,  by the
     Participant  or otherwise,  will be in such manner as the  Committee  deems
     equitable.

     Any notice or information which,  according to the terms of the Plan or the
     rules of the Committee,  must be filed with the Committee,  shall be deemed
     so filed at the time that it is actually received by the Committee.

     The  Employers,  the Committee,  and any person or persons  involved in the
     administration   of  the  Plan   shall  be   entitled   to  rely  upon  any
     certification, statement, or representation made or evidence furnished by a
     Participant  with  respect  to  his  age  or  other  facts  required  to be
     determined under any of the provisions of the Plan, and shall not be liable
     on account of the  payment of any monies or the doing of any act or failure
     to  act  in   reliance   thereon.   Any  such   certification,   statement,
     representation,  or evidence,  upon being duly made or furnished,  shall be
     conclusively  binding upon the person  furnishing same; but it shall not be
     binding upon the Employers,  the Committee,  or any other person or persons
     involved in the  administration  of the Plan, and nothing herein  contained
     shall be construed to prevent any of such parties from  contesting any such
     certification,  statement,  representation,  or  evidence or to relieve the
     Participant  from the  duty of  submitting  satisfactory  proof of any such
     fact.


                                       24


3.3  BENEFITS NOT ASSIGNABLE

     Except for any indebtedness of a Participant to an Employer, no benefits or
     rights  shall  exist  under the Plan  which are  subject  in any  manner to
     voluntary  or  involuntary   anticipation,   alienation,   sale,  transfer,
     assignment, pledge, encumbrance or charge and any attempt so to anticipate,
     alienate,  transfer,  assign, pledge,  encumber or charge the same shall be
     void;  nor shall any such  benefit or right be in any manner  liable for or
     subject to the debts, contracts,  liabilities,  engagements, torts or other
     obligations  of the person  entitled  to such  benefit or right,  except as
     specifically provided in the Plan; nor shall any benefit or right under the
     Plan  constitute  an asset of a  Participant  or of any person  entitled to
     benefits under the Plan in case of the bankruptcy,  receivership or divorce
     of said  person;  and any such  benefit  or right  shall  be  payable  only
     directly to the Participant or to his surviving spouse.

     If a Participant  or any other person  entitled to benefits under this Plan
     becomes  bankrupt or makes an assignment for the benefit of creditors or in
     any way suffers a lien or judgment against his personal  assets,  or in any
     way attempts to anticipate,  alienate,  sell, assign,  pledge,  encumber or
     charge a benefit or right,  except as  specifically  provided  in the Plan,
     then such benefit or right in the discretion of the Committee may cease and
     terminate.


                                       25


3.4  CONDITIONS OF EMPLOYMENT NOT AFFECTED BY PLAN

     The  establishment  and  maintenance  of the Plan will not be  construed as
     conferring any legal rights upon any Participant to the continuation of his
     employment with an Employer,  nor will the Plan interfere with the right of
     an  Employer to  discipline,  lay off or  discharge  any  Participant.  The
     adoption and  maintenance  of the Plan shall not be deemed to  constitute a
     contract  between the Employer  and any  Employee or to be a  consideration
     for, inducement to, or condition of employment of any person.

3.5  ABANDONMENT OF BENEFITS

     Each Participant and other person entitled to benefits hereunder shall file
     with the Committee  from time to time, in writing,  his post office address
     and each change of post office address,  and any check representing payment
     hereunder  and any  communication  addressed  to a  Participant,  a retired
     Participant,  or a surviving  spouse at his or her last address  filed with
     the  Committee  (or, if no such  address  has been filed,  then at his last
     address as  indicated on the records of the  Employer)  shall be binding on
     such person for all purposes of the Plan,  and the  Committee  shall not be
     obliged to search for or ascertain the location of any such person.

     If the  Committee,  for any  reason,  is in doubt as to whether  retirement
     income payments are being received by the person entitled thereto,  it may,
     by registered  mail  addressed to the person  concerned at his address last
     known to the  Committee,  notify such person that all  unmailed  and future
     retirement  income payments shall be henceforth  withheld until he provides
     the Committee  with evidence of his continued  life and his proper  mailing


                                       26


     address.  Further, his right to any retirement income whatsoever including,
     without limitation, payments withheld as provided in the preceding sentence
     and  payment  checks  returned  or not cashed  shall,  at the option of the
     Committee,  be cancelled  forever if, at the expiration of three years from
     the date of such mailing,  he shall not have  provided the  Committee  with
     evidence of his continued life and his proper mailing address.

3.6  WRITTEN COMMUNICATIONS REQUIRED

     Any notice,  request,  instruction,  or other  communication to be given or
     made hereunder shall be in writing and either  personally  delivered to the
     addressee  or  deposited  in the  United  States  mail fully  postpaid  and
     properly  addressed to such  addressee at the last address for notice shown
     on the  Committee's  records  (or if no  address  has been  filed  with the
     Committee,  then at the last address for such addresses as indicated on the
     records of the Employer).

3.7  CONDUCT INJURIOUS TO THE COMPANY

     Notwithstanding  anything in the Plan to the contrary, any and all benefits
     otherwise payable to any Participant hereunder, except to the extent of any
     prior  distributions  under the Plan,  shall be forever  forfeited if it is
     determined by the Committee, in its sole discretion,  that such Participant
     has  engaged in conduct  injurious  to the  Company  or any  Subsidiary  or
     Affiliated Company, including but not limited to the following:

     (a)  dishonesty  while in the employ Of the  Company or any  Subsidiary  or
          Affiliated Company;


                                       27


     (b)  imparting,  disclosing or  appropriating  proprietary  information for
          himself or to or for any other person, firm, corporation,  association
          or entity for any reason or purpose whatsoever,  except if required by
          law or at the Company's direction;

     (c)  performing  any act or engaging in any course of conduct  which has or
          may  reasonably  have the  effect of  demeaning  the name or  business
          reputation of the Company or any Subsidiary or Affiliated Company; and

     (d)  providing  goods  or  services  to or  becoming  an  employee,  owner,
          officer, agent, consultant,  advisor or director of any firm or person
          in  any  geographic  area  which  competes  with  the  Company  or any
          Subsidiary or  Affiliated  Company in any phase of any of the business
          lines  or  services  offered  by  the  Company  or any  Subsidiary  or
          Affiliated Company as of the Participant's Retirement Date.

     Any  determination  by the  Committee  that a  Participant  has  engaged in
     conduct  injurious to the Company  shall be  conclusive  and binding on all
     parties.

     the Plan and  will,  subject  to the  provisions  of the Plan,  decide  any
     questions arising in the administration,  interpretation and application of

     expedient.

     mistakes or errors  made in the  administration  of the Plan,  and all such
     actions or determinations  made by the Committee in good faith shall not be
     subject to review by anyone.


                                       29



4.4  LIABILITY OF COMMITTEE

     No member of the  Committee  shall be liable for any loss unless  resulting
     from his own fraud, bad faith or intentional wrongdoing and no member shall

     transaction or omission executed,  committed or suffered to be committed by
     the  Committee  or by himself as a member of the  Committee or by any other
     member, agent,  representative or employee of the Committee.  The Committee
     and any  individual  member of the Committee and any agent thereof shall be

     claims and causes of action whomsoever, and any losses therefrom, including
     without  limitation  costs of defense and  attorneys'  fees,  based upon or
     arising out of any act or omission  relating to or in connection  with this
     Plan, its  interpretation  or  administration,  other than losses resulting
     from the fraud, bad faith or intentional  wrongdoing of the party asserting

                                       30


4.6  APPLICABLE LAW

     The Plan shall be construed,  administered  and enforced in accordance with

     ERISA pre-emption does not apply.

                               GENERAL PROVISIONS

5.1  AMENDMENT AND DISCONTINUANCE

     The Plan may be  amended  from  time to time in any  respect  whatever,  by
     resolution  of the  Board  of  Directors  of the  Company  specifying  such
     amendment and amendments may be made  retroactively  which, in the judgment
     of the Committee,  is necessary or advisable provided that such retroactive
     amendment  does not  deprive  a retired  or  disabled  Participant,  or his
     spouse,  without  his  or her  consent,  of a  right  to  receive  benefits
     hereunder.

     The participation in the Plan of Employers other than the Company shall not
     limit  the  power  of  the  Company  under  the  foregoing  provision,  and
     amendments by the Company shall be binding upon all other  Employers to the
     extent accepted by such  Employers.  Acceptance by each such Employer shall
     be presumed.  However the  discontinuance  of the Plan shall not affect the
     rights of retired  or  disabled  Participants  (or their  spouses)  who are
     receiving benefits under this Plan on the date of such discontinuance.

     be paid from the general assets of the Company and all benefits  payable to
     Participants  of any  Subsidiary  or Affiliate  which has adopted this Plan

     spouses  hereunder.  No Participant or surviving spouse or any other person
     shall  have,  under  any  circumstances,   any  interest  whatever  in  any
     particular property or assets of the Company or any Subsidiary or Affiliate
     by virtue of this Plan.
