              TRANSOCEAN SEDCO FOREX AND R&B FALCON RECEIVE SECOND
               REQUEST FOR INFORMATION FROM DEPARTMENT OF JUSTICE

         HOUSTON--Transocean Sedco Forex Inc. (NYSE: RIG) and R&B Falcon
Corporation (NYSE: FLC) today jointly announced that both companies have
received a second request for information and documentary materials from the
Department of Justice (DOJ) pertaining to the previously announced acquisition
of R&B Falcon by Transocean Sedco Forex. The information request was received
pursuant to the Hart-Scott-Rodino Antitrust Improvement Act of 1976 and is
intended to assist the DOJ in completing its competitive analysis of the
proposed merger.

         Both Transocean Sedco Forex and R&B Falcon intend to respond promptly
to the information request, which has the effect of extending the waiting period
under antitrust law by 20 calendar days following both companies' compliance
with the request. The companies do not expect that there will be any delay to
the anticipated first quarter 2001 closing of the transaction as a result of the
second request.

         On August 21, 2000, Transocean Sedco Forex announced that it had signed
a definitive agreement to acquire R&B Falcon in an all stock transaction in
which common stockholders of R&B Falcon will receive a fixed ratio of 0.5 shares
of newly issued Transocean Sedco Forex ordinary shares for each R&B Falcon
share.

         Statements regarding the consummation of the acquisition, closing date
of the transaction and any other statements that are not historical facts, are
forward-looking statements that involve certain risks, uncertainties and
assumptions. Transocean Sedco Forex Inc. and R&B Falcon Corporation strongly
encourage readers to note that some or all of the assumptions, upon which such
forward-looking statements are based, are beyond their ability to control or
estimate precisely, and may in some cases be subject to rapid and material
changes. The risks, uncertanties and assumptions relate to matters that include
but are not limited to actions or approvals of third parties, delays in the
merger, closing conditions not being satisfied and other factors detailed in
Transocean Sedco Forex's and R&B Falcon Corporation's filings with the
Securities and Exchange Commission (SEC), which are available free of charge on
the SEC's website at www.sec.gov. Should one or more of these risks or
uncertainties materialize, or should underlying assumptions prove incorrect,
actual results may vary materially from those indicated.
