          the terms hereof.

     5.   The  Option may be exercised by the Optionee, in  whole
          or   in   part,  by  giving  written  notice   to   the
          Compensation  and Benefits Department  of  the  Company
          setting  forth the number of Option Shares with respect
          to  which the option is to be exercised, accompanied by
          payment  for  the  shares  to  be  purchased  and   any

          address to which the certificate for such shares is  to
          be  mailed (or to the extent permitted by the  Company,
          the  written  instructions  referred  to  in  the  last
          sentence  of this section).  Payment shall be by  means
          of  cash,  certified check, bank draft or postal  money

          notification and payment, the Company shall deliver, or
          cause to be delivered, to the Optionee certificates for
          the  number of Option Shares with respect to which  the
          Option has been so exercised.

     6.   Subject  to  approval of the Committee, which shall not
          be  unreasonably withheld, the Optionee may pay for any

          Common  Stock  at the time of the exercise  or  partial
          exercise  hereof.  The  certificates  representing such
          other  shares  of Common Stock must be accompanied by a
          stock power  duly executed with signature guaranteed in
          accordance  with market  practice.  The  value  of  the
          Common Stock so tendered shall be its Fair Market Value.

     7.   A.   If  the Optionee's employment with the Company  is
          terminated by the Company for Cause or is terminated by
          the  Optionee   (other  than by reason  of  retirement,
          death,  Disability or Good Reason or  during  a  Window
          Period),   (a) the options herein granted to  him  that
          are  not exercisable on the date of his termination  of
          employment  shall  thereupon  terminate,  and  (b)  any
          options  herein granted to him that are exercisable  on
          the  date  of  his  termination of  employment  may  be
          exercised  by the Optionee during a three-month  period
          beginning on such date, unless the Option Period  shall
          expire   prior  to  such  date,  and  shall  thereafter
          terminate.

          B.  If  the  Optionee's employment with the Company  is
          terminated:   (i) by the Optionee for  Good  Reason  or
          during  a  Window Period; (ii) for any  reason  by  the
          Company  other  than for Cause or (iii)  by  reason  of
          retirement, death or Disability of Optionee,  then  (a)
          the options granted to him that are not exercisable  on
          the  date  of such termination of employment  shall  be
          thereupon  be  fully exercisable, and (b)  all  options
          then   held   by  the  Optionee,  whether   theretofore
          exercisable or exercisable by reason of the termination
          of  employment may be exercised by the Optionee  during
          the  full  remaining  term of  this  Option;  provided,
          however,  that  all  options  granted  hereunder  shall
          expire  and not be exercisable on the first anniversary
          of the Optionee's death.

     8.   The  Option  shall not be transferable by the  Optionee
          otherwise  than  as expressly permitted  by  the  Plan.
          During  the lifetime of the Optionee, the Option  shall
          be  exercisable only by her or him. No transfer of  the
          Option  shall  be effective to bind the Company  unless
          the  Company  shall  have been furnished  with  written
          notice  thereof  and  a copy of such  evidence  as  the
          Committee may deem necessary to establish the  validity
          of the transfer and the acceptance by the transferee or
          transferees of the terms and conditions hereof.

     9.   The Optionee shall have no rights as a stockholder with
          respect to any Option Shares until the date of issuance
          of  a  certificate for Option Shares purchased pursuant
          to this Agreement.  Until such time, the Optionee shall
          not be entitled to dividends or to vote at meetings  of
          the stockholders of the Company.

     10.  The  Company  may make such provisions as it  may  deem
          appropriate for the withholding of any taxes  which  it
          determines  is required in connection with  the  option
          herein  granted.   The Optionee  may  pay  all  or  any
          portion  of  the taxes required to be withheld  by  the
          Company or paid by the Optionee in connection with  the
          exercise  of  all or any portion of the  option  herein
          granted by electing to have the Company withhold shares
          of  Common  Stock,  or by delivering  previously  owned
          shares  of  Common  Stock, having a Fair  Market  Value
          equal  to  the amount required to be withheld or  paid.
          The  Optionee  must make the foregoing election  on  or
          before  the date that the amount of tax to be  withheld
          is  determined  ("Tax  Date").  Any  such  election  is
          irrevocable   and   subject  to  disapproval   by   the
          Committee.   If the Optionee is subject to  the  short-
          swing profits recapture provisions of Section 16(b)  of
          the Exchange Act, any such election shall be subject to
          the following additional restrictions:

          (a)  Such election may not be made within six months of
          the grant of this option, provided that this limitation
          shall not apply in the event of death or Disability.

          (b)    Such election must be made either in an Election
          Window  (as hereinafter defined) or at such other  time
          as may be consistent with Section 16(b) of the Exchange
          Act  and  the rules promulgated thereunder.  Where  the
          Tax  Date  in  respect of the exercise of  all  or  any
          portion  of  this Option is deferred until  after  such
          exercise and the Optionee elects stock withholding, the
          full amount of shares of Common Stock will be issued or
          transferred  to  the  Optionee upon  exercise  of  this
          Option,  but  the  Optionee  shall  be  unconditionally
          obligated to tender back to the Company on the Tax Date
          the  number  of  shares  necessary  to  discharge  with
          respect to such Option exercise the greater of (i)  the
          Company's  withholding obligation and (ii) all  or  any
          portion   of  the  holder's  federal  and   state   tax
          obligation  attributable to the  Option  exercise.   An
          Election  Window is any period commencing on the  third
          business  day  following  the Company's  release  of  a
          quarterly  or  annual summary statement  of  sales  and
          earnings  and  ending  on  the  twelfth  business   day
          following such release.

     11.  Upon  the  acquisition of any shares  pursuant  to  the
          exercise  of the Option, the Optionee will  enter  into
          such written representations, warranties and agreements
          as  the  Company  may reasonably request  in  order  to
          comply  with  applicable securities laws or  with  this
          Agreement.

     12.  The   certificates  representing  the   Option   Shares
          purchased  by exercise of an option will be stamped  or
          otherwise imprinted with a legend in such form  as  the
          Company or its counsel may require with respect to  any
          applicable  restrictions on sale or transfer,  and  the
          stock transfer records of the Company will reflect stop-
          transfer instructions, as appropriate, with respect  to
          such shares.

     13.  Unless   otherwise   provided  herein,   every   notice
          hereunder shall be in writing and shall be delivered by
          hand  or  by registered or certified mail.  All notices
          of the exercise by the Optionee of any option hereunder
          shall be directed to R&B Falcon Corporation, Attention:
          Benefits  and Compensation Department, at the Company's
          principal office address from time to time.  Any notice
          given by the Company to the Optionee directed to him or
          her  at  his  or her address on file with  the  Company
          shall  be effective to bind any other person who  shall
          acquire  rights hereunder.  The Company shall be  under
          no  obligation whatsoever to advise the Optionee of the
          existence,  maturity  or  termination  of  any  of  the
          Optionee's rights hereunder and the Optionee  shall  be
          deemed  to  have familiarized himself with all  matters
          contained  herein and in the Plan which may affect  any
          of the Optionee's rights or privileges hereunder.

     14.  Whenever  the  term  "Optionee" is  used  herein  under
          circumstances applicable to any other person or persons
          to  whom  this award, in accordance with the provisions
          of Paragraph 8, may be transferred, the word "Optionee"
          shall  be  deemed  to include such person  or  persons.
          References to the masculine gender herein also  include
          the feminine gender for all purposes.

     15.  Notwithstanding any of the other provisions hereof, the
          Optionee  agrees that he or she will not  exercise  the
          Option,  and that the Company will not be obligated  to
          issue  any  shares pursuant to this Agreement,  if  the
          exercise  of the Option or the issuance of such  shares
          of  Common  Stock would constitute a violation  by  the
          Optionee or by the Company of any provision of any  law
          or  regulation  of  any governmental authority  or  any
          national securities exchange.

          subsequent amendments thereto) are incorporated  herein

          term  or  provision  contained herein  and  a  term  or
          provision  of  the  Plan,   the  applicable  terms  and
          provisions  of the Plan will govern and  prevail.   All
          definitions  of words and terms contained in  the  Plan
          shall be applicable to this Agreement.

     17.  In  the  event  of  a  corporate merger  or  other  business
          combination  in  which  the Company  is  not  the  surviving
          entity, the economic equivalent number of the voting  shares
          of  common  stock  of, or participating  interests  in,  the
          surviving entity, based on the terms of such merger or other
          business combination, shall be substituted for the number of
          Option  Shares  held  by  the Optionee  hereunder,  and  the
          exercise price per share set out in Paragraph 3 above  shall
          be  likewise  adjusted,  to reflect substantially  the  same
          economic  equivalent  value of  the  Option  Shares  to  the
          Optionee   prior  to  any  such  merger  or  other  business
          combination.   In  the  event of a  split-off,  spin-off  or
          creating of a different class of common stock of the Company

          number of the shares of common stock or voting interests  of
          such  separate entity being split-off or spun-off or of  the
          shares  of the new class of common stock of the Company,  as
          if  Optionee  had  owned  the shares underlying  the  Option
          Shares  on the record date for any such split-off,  spin-off
          or  creation of a new class of common stock of the  Company,
          and  the  exercise price set out in Paragraph 3  hereof  and
          applicable  to the options to purchase shares or the  voting
          interests  of  the  new entity being split-off  or  spun-off
          shall be adjusted to reflect substantially the same economic
          equivalent value of the Option Shares to the Optionee  prior
          to  any such split-off, spin-off or creation of a new  class
          of common stock of the Company.


     IN  WITNESS WHEREOF, this Agreement is executed this _ _  day  of
