    Transocean Sedco Forex offers, on the terms and subject to the conditions
set forth in this prospectus and consent solicitation statement and the
accompanying letter of transmittal and consent, to issue, in exchange for
properly tendered and accepted R&B Falcon notes of any series listed above, new
Transocean Sedco Forex notes having the same principal amount, interest rate,
redemption terms and payment and maturity dates (and accruing interest from the
last date for which interest has been paid on those R&B Falcon notes). In
addition, R&B Falcon will pay an amount in cash equal to the applicable consent
payment listed above to each holder of R&B Falcon notes accepted for exchange if
the holder has tendered those notes prior to the consent payment deadline
referred to below.

    A holder validly tendering notes for exchange will, by tendering those
notes, be consenting to the amendments to the indenture under which those notes
were issued described under "The Proposed Amendments." Transocean Sedco Forex's
obligation to complete each exchange offer and cause R&B Falcon to make the
consent payments relating to that exchange offer is conditioned upon, among
other things, receipt of valid consents sufficient to effect these amendments
with respect to all six series of notes listed above, although Transocean Sedco
Forex will be free to waive this or any other condition with respect to any or
all of the exchange offers. For information about other conditions to Transocean
Sedco Forex's obligation to complete the exchange offers and cause R&B Falcon to
make the consent payments, see "Conditions to the Exchange Offers and Consent
Solicitations."


The consent payment deadline for each exchange offer (that is, the time by which
holders must tender the applicable series of R&B Falcon notes in order to be
eligible to receive the consent payment) will be Midnight, New York City time,
on February 13, 2002, unless extended. Consents may be revoked at any time prior
to the consent payment deadline.



Each exchange offer will expire at 5:00 p.m., New York City time, on March 1,
2002, unless extended. Tenders may be withdrawn at any time prior to the
expiration date.


    Transocean Sedco Forex does not intend to list the Transocean Sedco Forex
notes to be issued in the exchange offers on any national securities exchange or
on The Nasdaq Stock Market.

     For a discussion of the risks that you should consider in evaluating the
exchange offers and consent solicitations, see "Risk Factors" beginning on page
14.

    NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THE SECURITIES BEING OFFERED IN THE
EXCHANGE OFFERS OR PASSED UPON THE ADEQUACY OR ACCURACY OF THIS PROSPECTUS AND
CONSENT SOLICITATION STATEMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL
OFFENSE.

                               PROSPECTUS SUMMARY

     The following summary does not purport to be complete and is qualified in
its entirety by, and should be read in conjunction with, the more detailed
financial information and consolidated financial statements, including the notes
thereto, included or incorporated by reference in this prospectus and consent
solicitation statement. In particular, holders of R&B Falcon notes should
carefully consider the information set forth under "Risk Factors."

                          TRANSOCEAN SEDCO FOREX INC.

     We are a leading international provider of offshore and inland marine
contract drilling services for oil and gas wells. We are the result of the
merger of Transocean Offshore Inc. and Sedco Forex Holdings Limited in December
1999, and the subsequent merger with R&B Falcon Corporation in January 2001. On
December 31, 2001, Transocean Sedco Forex owned, had partial ownership interests
in or operated more than 160 mobile offshore and barge drilling units.
Transocean Sedco Forex's active fleet consists of 31 high-specification
drillships and semisubmersibles (floaters), 30 other floaters, 54 jackup rigs,
35 drilling barges, four tenders and three submersible drilling rigs. In
addition, the fleet includes mobile offshore production units, platform drilling
rigs and land and barge drilling rigs in Venezuela.

     Our primary business is to contract our drilling rigs, related equipment
and work crews on a dayrate basis to drill oil and gas wells. We specialize in
technically demanding segments of the offshore drilling business with a
particular focus on deepwater and harsh environment drilling services. We also
provide additional services, including management of third-party well service
activities.

     We are the world's largest offshore drilling company as measured by the
number of mobile offshore drilling units and equity market capitalization. We
have the largest fleet of rigs capable of working in water depths greater than
3,000 feet, as well as the largest fleet of jackup rigs and drilling barges. We
believe our diverse fleet positions us with the necessary geographical coverage,
technical capabilities, efficiencies and resources to meet our customers' needs
and to attract new customers.

     We have a significant presence in all major offshore oil and gas drilling
areas, including the North Sea, West Africa, the U.S. Gulf of Mexico, Brazil and
Asia. Our infrastructure in these areas helps us meet our customers' needs on a
global basis and is set up to provide regional economies of scale. Our

                   TRANSOCEAN SEDCO FOREX SELECTED HISTORICAL
                   AND PRO FORMA CONSOLIDATED FINANCIAL DATA

     On December 31, 1999, the merger of Transocean Offshore Inc. and Sedco
Forex Holdings Limited was completed. Sedco Forex was the offshore contract
drilling service business of Schlumberger Limited and was spun off the day
before the merger transaction. As a result of the merger, Sedco Forex became a
wholly owned subsidiary of "Transocean Offshore Inc.", which changed its name to
Transocean Sedco Forex Inc. The merger was accounted for as a purchase, with
Sedco Forex as the acquiror for accounting purposes.

     Transocean Sedco Forex prepared the selected historical consolidated
financial data in the following table using the consolidated financial
statements of Transocean Sedco Forex. Transocean Sedco Forex derived the
statement of operations and other financial data for the year ended December 31,
2000 and the balance sheet data as of December 31, 2000 and 1999 from its
consolidated financial statements and the statement of operations and other
financial data for the year ended December 31, 1999 from its combined financial
statements audited by Ernst & Young LLP, independent auditors. Transocean Sedco
Forex derived the statement of operations and other financial data for each of
the three years in the period ended December 31, 1998, and the balance sheet
data as of December 31, 1998 and 1997, from its combined financial statements
audited by PricewaterhouseCoopers LLP, independent accountants. Transocean Sedco
Forex derived the statement of operations and other financial data for the nine
months ended September 30, 2001 and 2000 and the balance sheet data as of
September 30, 2001 and 2000 from its unaudited consolidated financial statements
and the balance sheet data as of December 31, 1996 from its unaudited combined
financial statements. The unaudited interim financial statements for the nine
months ended September 30, 2001 and 2000 include all adjustments, consisting of
normal recurring adjustments, which Transocean Sedco Forex considers necessary
for a fair presentation of the financial position and the results of operations
for these periods. Operating results for the nine months ended September 30,
2001 are not necessarily indicative of the results that may be expected for the
entire year ended December 31, 2001. The data should be read in conjunction with
the related notes and other financial information incorporated by reference in
this prospectus and consent solicitation statement.

     The balance sheet data as of December 31, 2000 and 1999 and September 30,
2001 and 2000 represent the consolidated financial position of Transocean Sedco
Forex, and the balance sheet data as of dates prior to the Transocean Offshore
Inc. and Sedco Forex merger reflect the financial position of Sedco Forex and
not that of historical Transocean Offshore Inc. The income statement data and
other financial data for the year ended December 31, 2000 and the nine months
ended September 30, 2001 and 2000 represent the operating results of Transocean
Sedco Forex and, for the periods prior to the Transocean Offshore Inc. and Sedco
Forex merger, reflect the operating results of Sedco Forex and not that of
historical Transocean Offshore Inc.

     On January 31, 2001 Transocean Sedco Forex completed a merger transaction
with R&B Falcon. As a result of the merger, R&B Falcon became an indirect wholly
owned subsidiary of Transocean Sedco Forex. The merger was accounted for as a
purchase and Transocean Sedco Forex was the accounting acquiror. The selected
historical consolidated financial data as of and for the nine months ended
September 30, 2001 include eight months of operating results and cash flows for
R&B Falcon.

     The pro forma consolidated statement of operations data assume that the
merger between Transocean Sedco Forex and R&B Falcon was completed on January 1,
2000. The pro forma information does not necessarily indicate what the operating
results of the combined company would have been had the merger been completed on
January 1, 2000, or what the future operating results of the combined company
will be. In particular, the unaudited pro forma consolidated statement of
operations data do not include adjustments to reflect any cost savings or other
operational efficiencies that may be realized as a result of the merger of
Transocean Sedco Forex and R&B Falcon, or any future merger-related
restructuring or integration expenses.

                                        3


The pro forma consolidated statement of operations data for Transocean Sedco
Forex assumes the exchange offers were completed as of January 1, 2000 and that
all R&B Falcon notes were tendered by the applicable consent payment deadline
and not withdrawn. The historical financial information has been derived from
the consolidated financial statements of Transocean Sedco Forex and R&B Falcon
for the periods presented.

---------------

(a) Unaudited pro forma earnings per share for the years ended December 31, 1996
    through 1999 was calculated using the Transocean Sedco Forex Inc. ordinary
    shares issued pursuant to the Sedco Forex merger agreement and the dilutive
    effect of Transocean Sedco Forex Inc. stock options granted to former Sedco
    Forex employees at the time of the Sedco Forex merger, as applicable.

(b) EBITDA (earnings before interest, taxes, depreciation and amortization) is
    presented here because it is a widely accepted financial indication of a
    company's ability to incur and service debt. EBITDA measures presented may
    not be comparable to similarly titled measures used by other companies.
    EBITDA is not a measurement presented in accordance with accounting
    principles generally accepted in the United States ("GAAP") and is not
    intended to be used in lieu of GAAP presentations of results of operations
    and cash provided by operating activities.

                   R&B FALCON CORPORATION SELECTED HISTORICAL
                          CONSOLIDATED FINANCIAL DATA

     R&B Falcon prepared the selected historical consolidated financial data in
the table below using the consolidated financial statements of R&B Falcon. R&B
Falcon derived the statement of operations data below for each of the five years
in the period ended December 31, 2000, and the consolidated balance sheet data
as of December 31 of each year from 1996 to 2000, from its financial statements
audited by Arthur Andersen LLP, independent public accountants. R&B Falcon
derived the consolidated statement of operations data for the nine months ended
September 30, 2001 and 2000 and the consolidated balance sheet data as of
September 30, 2001 and 2000 from its unaudited consolidated financial statements
which, in the opinion of management, include all adjustments, consisting only of
normal recurring adjustments, necessary for a fair statement of the results for
the unaudited interim periods. Operating results for the nine months ended
September 30, 2001 are not necessarily indicative of the results that may be
expected for the entire year ending December 31, 2001.

     On January 31, 2001, Transocean Sedco Forex completed a merger transaction
with R&B Falcon. As a result of the merger, R&B Falcon became a wholly owned
subsidiary of Transocean Sedco Forex. The merger was accounted for as a purchase
and Transocean Sedco Forex was the accounting acquiror. The purchase price was
allocated to the assets and liabilities of R&B Falcon based on their estimated
fair values on the date of the merger. Accordingly, the financial statements of
R&B Falcon for periods subsequent to January 31, 2001 are not comparable to
those of prior periods in material respects since those financial statements
report financial position, results of operations and cash flows using a
different basis of accounting.

     The pro forma statement of operations data below for the nine months ended
September 30, 2001 and for the year ended December 31, 2000 assumes the merger
transaction with Transocean Sedco Forex and the sale of drilling units described
in "Certain Related Transactions" were completed on January 1, 2000. The pro
forma consolidated statement of operations data also assumes the exchange offers
were completed as of January 1, 2000 and that all R&B Falcon notes were tendered
by the applicable consent payment deadline and not withdrawn.

     The unaudited consolidated statement of operations data for the eight
months ended September 30, 2001, one month ended January 31, 2001 and nine
months ended September 30, 2000 contain certain reclassifications to conform the
presentation of operating results with that of Transocean Sedco Forex. These
reclassifications were not made in the annual periods 2000 and prior. None of
the reclassifications had an effect on the consolidated net loss from continuing
operations.

    (a) Included in 1999 are expenses of $34.7 million in connection with the
        cancellation of certain drillship projects and $3.7 million of oil and
        gas development expenses.

    (b) Included in 1998 are expenses of $118.3 million in connection with the
        cancellation of certain drillship projects, $19.5 million of oil and gas
        development expenses and the reversal of $8.0 million of expenses in
        connection with the merger of Reading & Bates Corporation and Falcon
        Drilling Co. in December 1997, which was accounted for as a pooling of
        interests.

    (c) Included in 1997 are expenses of $66.4 million in connection with the
        merger of Reading & Bates Corporation and Falcon Drilling Co. in
        December 1997, which was accounted for as a pooling of interests.
        Additionally, R&B Falcon incurred oil and gas development expenses and
        charges of $130.2 million in 1997.

    (d) Effective with the merger with Transocean Sedco Forex on January 31,
        2001, R&B Falcon became a wholly owned subsidiary of Transocean Sedco
        Forex. In conjunction with the merger, the R&B Falcon common
        shareholders received .5 newly issued Transocean Sedco Forex ordinary
        shares for each R&B Falcon share. As a result, no earnings per share
        information is shown for post-merger financial information.

    (e) EBITDA (income (loss) from continuing operations before extraordinary
        items and minority interest, interest, net, taxes, depreciation and
        amortization) is presented here because it is a widely accepted
        financial indication of a company's ability to incur and service debt.
        EBITDA measures presented may not be comparable to similarly titled
        measures used by other companies. EBITDA is not a measurement presented
        in accordance with accounting principles generally accepted in the

                QUESTIONS AND ANSWERS ABOUT THE EXCHANGE OFFERS
                           AND CONSENT SOLICITATIONS

Q:   WHY IS TRANSOCEAN SEDCO FOREX MAKING THE EXCHANGE OFFERS AND THE CONSENT
     SOLICITATIONS?

A:   As a result of the merger on January 31, 2001, R&B Falcon became an
     indirect wholly owned subsidiary of Transocean Sedco Forex. Since the
     merger, Transocean Sedco Forex has been operationally and financially
     integrating R&B Falcon into the Transocean Sedco Forex organization. See
     "Certain Related Transactions" for a description of some of these
     integration transactions. The exchange offers and the proposed amendments
     are intended to provide us with greater operational and financial
     flexibility, including greater flexibility in continuing our integration
     efforts, and to allow us to structure our operations and the operations of
     our subsidiaries in a more efficient manner and allow for potential
     savings.

Q:   WHAT WILL I RECEIVE IN THE EXCHANGE OFFERS AND CONSENT SOLICITATIONS?

A:   For each $1,000 principal amount of any series of R&B Falcon notes validly
     tendered and accepted for exchange, Transocean Sedco Forex is offering
     $1,000 principal amount of Transocean Sedco Forex's newly issued notes of a
     corresponding series. Each series of Transocean Sedco Forex notes being
     offered under this prospectus and consent solicitation statement will have
     the same principal amount, interest rate, redemption terms and payment and
     maturity dates as those of the corresponding series of R&B Falcon notes to
     be exchanged in the exchange offers, and will be issued under and governed
     by the terms of the indenture under which Transocean Sedco Forex's existing
     debt securities were issued. Instead of receiving a payment for accrued
     interest on R&B Falcon notes you exchange, the Transocean Sedco Forex notes
     you receive in exchange for those R&B Falcon notes will accrue interest
     from the last date to which interest has been paid on those R&B Falcon
     notes.


     In addition, R&B Falcon will pay an amount in cash equal to the applicable
     consent payment listed on the cover page of this prospectus and consent
     solicitation statement to each holder of R&B Falcon notes accepted for
     exchange if the holder has tendered those notes prior to the applicable
     consent payment deadline. The consent payment deadline for each exchange
     offer (that is, the time by which holders must tender R&B Falcon notes into
     that offer in order to be eligible to receive the consent payment) will be
     Midnight, New York City time, on February 13, 2002, unless extended.


     AS A HOLDER OF R&B FALCON NOTES OF ANY SERIES, YOU MAY GIVE YOUR CONSENT TO
     THE PROPOSED AMENDMENTS TO THE R&B FALCON INDENTURES ONLY BY TENDERING YOUR
     R&B FALCON NOTES IN THE EXCHANGE OFFER FOR THAT SERIES. BY SO TENDERING,
     YOU WILL BE DEEMED TO HAVE GIVEN A CONSENT WITH RESPECT TO THE NOTES OF
     THAT SERIES.

Q:   WHAT ARE THE CONSEQUENCES OF NOT TENDERING IN THE EXCHANGE OFFERS?

A:   If the exchange offers are consummated and the proposed amendments to the
     R&B Falcon indentures have been adopted, they will apply to all R&B Falcon
     notes not acquired in the exchange offers. All R&B Falcon notes that remain
     outstanding after the consummation of the exchange offers will be governed
     by the R&B Falcon indentures as amended by the proposed amendments, which
     will have less restrictive terms and afford reduced protections to the
     holders of such securities compared to those currently in the R&B Falcon
     indentures. See "Risk Factors -- Risk Factors Relating to the Exchange
     Offers and Consent Solicitations -- The proposed amendments to the R&B
     Falcon indentures will afford reduced protection to holders of R&B Falcon's
     notes." In addition, holders that do not tender in the exchange offers
     prior to the consent payment deadline will not receive the applicable
     consent payment, even though the proposed amendments will become effective
     with respect to their R&B Falcon notes.

                                        8


Q:   HOW DO THE R&B FALCON NOTES DIFFER FROM THE TRANSOCEAN SEDCO FOREX NOTES TO
     BE ISSUED IN THE EXCHANGE OFFERS?

A:   The R&B Falcon notes are the obligations solely of R&B Falcon and are
     governed by the R&B Falcon indentures, while the Transocean Sedco Forex
     notes will be the obligations solely of Transocean Sedco Forex and will be
     governed by the Transocean Sedco Forex indenture. The R&B Falcon indentures
     and the Transocean Sedco Forex indenture differ in certain respects,
     including as follows:

     - The indenture for the R&B Falcon 9.125% notes and R&B Falcon 9.50% notes
       restricts R&B Falcon's ability to incur debt and to make distributions
       and other "restricted" payments, although these covenants are suspended
       during the time that such notes have investment grade ratings.

     - The R&B Falcon indentures restrict R&B Falcon's ability to merge or
       consolidate with, or sell substantially all of its assets to, a non-U.S.
       entity.

     - The provisions of the R&B Falcon indentures limiting the ability of R&B
       Falcon and its subsidiaries to incur liens are more restrictive than the
       corresponding provisions of the Transocean Sedco Forex indenture.

     These provisions will be eliminated from the R&B Falcon indentures,
     however, if the proposed amendments are adopted.

     See "Description of Differences Between the R&B Falcon Notes and the
     Transocean Sedco Forex Notes" and "Description of the Transocean Sedco
     Forex Notes."

     The Transocean Sedco Forex notes offered will be structurally subordinated
     to all obligations of Transocean Sedco Forex's subsidiaries, including any
     R&B Falcon debt securities not properly tendered and accepted for payment
     in the exchange offers, with respect to the assets of such subsidiaries. As
     of December 31, 2001, the aggregate amount of outstanding long-term debt of
     Transocean Sedco Forex's subsidiaries to which holders of the Transocean
     Sedco Forex notes would have been structurally subordinated was
     approximately $1,783.9 million, of which $1,537.9 million represented the
     carrying value of the six series of R&B Falcon notes for which Transocean
     Sedco Forex is making the exchange offers. See "Risk Factors -- Risks
     Relating to the Exchange Offers and Consent Solicitations -- Our holding
     company structure results in substantial structural subordination and may
     affect our ability to make payments on the Transocean Sedco Forex notes"
     and "Description of the Transocean Sedco Forex Notes -- Ranking; Additional
     Debt."

Q:   WHAT ARE THE U.S. FEDERAL INCOME TAX CONSEQUENCES TO HOLDERS THAT TENDER
     R&B FALCON NOTES IN THE EXCHANGE OFFERS?

A:   The receipt of Transocean Sedco Forex notes and consent payments in
     connection with the exchange offers and consent solicitations will be a
     taxable transaction for U.S. federal income tax purposes, and holders of
     R&B Falcon notes properly tendered (and not validly withdrawn) in the
     exchange offers will, accordingly, recognize gain or loss, as described in
     the section of the prospectus and consent solicitation statement entitled
     "Material U.S. Federal Income Tax Consequences."

Q:   WHAT CONSENTS ARE REQUIRED TO EFFECT THE PROPOSED AMENDMENTS TO THE R&B
     FALCON INDENTURES AND CONSUMMATE THE EXCHANGE OFFERS?


A:   Consents from holders of record of a majority of the total outstanding
     principal amount of a particular series of R&B Falcon notes as of the close
     of business on February 13, 2002 must be received in order to amend the R&B
     Falcon indenture with respect to that series.


     Transocean Sedco Forex's obligation to complete each exchange offer and
     cause R&B Falcon to make the consent payments relating to that exchange
     offer is conditioned upon, among other things, receipt of valid consents
     sufficient to effect the amendments with respect to all six series of R&B
     Falcon notes, although Transocean Sedco Forex will be free

                                        9


     to waive this or any other condition with respect to any or all of the
     exchange offers. For information about other conditions to Transocean Sedco
     Forex's obligation to complete the exchange offers and cause R&B Falcon to
     make the consent payments, see "Conditions to the Exchange Offers and
     Consent Solicitations."

Q:   WILL TRANSOCEAN SEDCO FOREX ACCEPT ALL TENDERS OF R&B FALCON NOTES?

A:   Subject to the satisfaction or waiver of the conditions to each exchange
     offer, Transocean Sedco Forex will accept for exchange any and all R&B
     Falcon notes of a series properly tendered (and not validly withdrawn) in
     the applicable exchange offer on or before the expiration date of that
     exchange offer.

Q:   WHEN WILL TRANSOCEAN SEDCO FOREX ISSUE NEW NOTES AND CAUSE CONSENT PAYMENTS
     TO BE MADE IN EXCHANGE FOR R&B FALCON NOTES?

A:   Assuming the conditions to the exchange offers are satisfied or waived,
     Transocean Sedco Forex will issue new notes in book-entry form and cause
     R&B Falcon to make consent payments in exchange for R&B Falcon notes on the
     third business day following the expiration date of the applicable exchange
     offer or as soon as practicable after that date.

Q:   WHEN DO I NEED TO TENDER MY R&B FALCON NOTES TO RECEIVE THE APPLICABLE
     CONSENT PAYMENT?


A:   The consent payment deadline for each exchange offer is Midnight, New York
     City time on February 13, 2002, unless extended. The consent payment
     deadline is the latest date and time on which you may tender your R&B
     Falcon notes and receive the applicable consent payment if these notes are
     exchanged.


Q:   WHEN DO THE EXCHANGE OFFERS EXPIRE?


A:   The exchange offers will expire at 5:00 p.m., New York City time, on March
     1, 2002, unless Transocean Sedco Forex, in its sole discretion, extends the
     exchange offers (or any of them) in which case the expiration date with
     respect to an exchange offer will be the latest date and time to which such
     exchange offer is extended. See "The Exchange Offers -- Consent Payment
     Deadline; Expiration Date; Extensions; Amendments."


Q:   WHAT ARE MY RIGHTS IF I CHANGE MY MIND AFTER I TENDER MY R&B FALCON NOTES?

A:   You may withdraw your tender at any time before the applicable exchange
     offer expires. A valid withdrawal of tendered R&B Falcon notes prior to the
     applicable consent payment deadline will constitute the revocation of the
     related consent to the proposed amendments to the applicable R&B Falcon
     indenture. You may only revoke a consent by validly withdrawing the related
     R&B Falcon notes prior to the consent payment deadline. See "The Exchange
     Offers -- Withdrawal of Tenders and Revocation of Corresponding Consents."

Q:   HOW DO I EXCHANGE MY R&B FALCON NOTES IF I AM A BENEFICIAL OWNER OF R&B
     FALCON NOTES HELD OF RECORD BY A CUSTODIAN BANK, DEPOSITARY, BROKER, TRUST
     COMPANY OR OTHER NOMINEE? WILL THE RECORD HOLDER EXCHANGE MY R&B FALCON
     NOTES FOR ME?

A:   If your R&B Falcon notes are held by a custodian bank, depositary, broker,
     trust company or other nominee and you wish to tender the securities in the
     exchange offers, you should contact that institution promptly and instruct
     the institution to tender on your behalf. The record holder will tender
     your securities on your behalf, but only if you instruct the record holder
     to do so. See "The Exchange Offers -- Procedures for Tendering -- Tender of
     R&B Falcon Notes Held through a Nominee."

Q:   DO I HAVE THE RIGHT TO DISSENT FROM THE EXCHANGE OFFERS OR SEEK APPRAISAL
     OF THE R&B FALCON NOTES I HOLD?

A:   Holders of R&B Falcon notes do not have any appraisal or dissenters' rights
     under New York law, the law governing the R&B Falcon indentures, or under
     the terms of the R&B Falcon indentures in connection with the exchange
     offers and consent solicitations.

                                        10


Q:   TO WHOM SHOULD I DIRECT ANY QUESTIONS?

A:   Questions concerning the terms of the exchange offers or the consent
     solicitations should be directed to the dealer managers. Questions
     concerning tender procedures and requests for additional copies of this
     prospectus and consent solicitation statement should be directed to the
     information agent. The addresses and telephone numbers of the dealer
     managers and the information agent are set forth on the back cover page of
     this prospectus and consent solicitation statement.

                             TRANSOCEAN SEDCO FOREX
                       RATIO OF EARNINGS TO FIXED CHARGES

     Transocean Sedco Forex's ratio of earnings to fixed charges for each of the
periods shown is as follows:



                                           NINE MONTHS

Historical ratio of earnings to fixed
  charges as adjusted for pro forma
  effect of the merger(b)...............       2.0         --


---------------

(a)  The ratios for each of the years in the four year period ended December 31,
     1999 include only the earnings and fixed charges of Sedco Forex and not
     those of Transocean Offshore Inc.

(b)  Historical ratio of earnings to fixed charges as adjusted for the pro forma
     effect of the merger were insufficient to cover fixed charges by $131.1
     million for the year ended December 31, 2000.

     We have computed the ratios of earnings to fixed charges shown above by
dividing earnings available for fixed charges by fixed charges. For this
purpose, "earnings available for fixed charges" consist of pretax income (loss)
from continuing operations before extraordinary items plus fixed charges,
distributed earnings of unconsolidated joint ventures and amortization of
capitalized interest, less capitalized interest and undistributed equity in
earnings of unconsolidated joint ventures. "Fixed charges" consist of interest
expense, capitalized interest and an estimate of the interest within rental
expense.

     On January 31, 2001, we completed our merger transaction with R&B Falcon.
The merger was accounted for as a purchase, with our company as the acquiror for
accounting purposes. The historical ratios of earnings to fixed charges for the
year ended December 31, 2000 include only the earnings and fixed charges of
Transocean Sedco Forex.

     Historical ratio of earnings to fixed charges as adjusted for the pro forma
effect of the merger for the year ended December 31, 2000 and the nine months
ended September 30, 2001 assume that we completed the merger transaction with
R&B Falcon on January 1, 2000. This pro forma information does not necessarily
reflect what the ratio of earnings to fixed charges would have been if the
merger had been completed on that date nor does it necessarily reflect any
future ratio of earnings to fixed charges.

     The pro forma effect of this exchange offer is not included or required
since it has an insignificant (less than 10 percent) effect on the historical
ratios.

                                        12


                 R&B FALCON RATIO OF EARNINGS TO FIXED CHARGES

     For purposes of computing the ratio of earnings to fixed charges, "earnings
available for fixed charges" consist of pretax income (loss) from continuing
operations before extraordinary items and minority interest plus fixed charges,
distributed earnings of unconsolidated joint ventures and amortization of
capitalized interest, less capitalized interest and undistributed equity in
earnings of unconsolidated joint ventures and minority interest in pre-tax
income of subsidiaries that have not incurred fixed charges. "Fixed charges"
consist of interest expense, capitalized interest and an estimate of the
interest within rental expense.

     The following table sets forth our consolidated ratio of earnings to fixed
charges for the periods shown:

---------------

(a)  For the eight months ended September 30, 2001, the one month ended January
     31, 2001 and for the years ended December 31, 2000 and 1999, earnings were
     insufficient to cover fixed charges by $31.1 million, $127.3 million, $44.3
     million and $185.0 million, respectively.
(b)  Historical ratio of earnings to fixed charges as adjusted for pro forma
     effect of the merger were insufficient to cover fixed charges by $80.7
     million and $189.3 million for the nine months ended September 30, 2001 and
     for the year ended December 31, 2000, respectively.

     On January 31, 2001, we completed our merger transaction with Transocean
Sedco Forex. The merger was accounted for as a purchase, with Transocean Sedco
Forex as the acquiror for accounting purposes. The historical ratios of earnings
to fixed charges for the five years ended December 31, 2000 and the one month
ended January 31, 2001 include the earnings and fixed charges for R&B Falcon
prior to the merger.

     The historical ratio of earnings to fixed charges as adjusted for pro forma
effect of the merger for the year ended December 31, 2000 and the nine months
ended September 30, 2001 assume that we completed the merger transaction with
Transocean Sedco Forex and the rig sales on January 1, 2000. This pro forma
information does not necessarily reflect what the ratio of earnings to fixed
charges would have been if the merger had been completed on that date nor does
it necessarily reflect any future ratio of earnings to fixed charges.

     The pro forma effect of this exchange offer is not included or required
since it has an insignificant (less than 10 percent) effect on the historical
ratios.

                                  RISK FACTORS

     In addition to the other information contained in this prospectus and
consent solicitation statement and the documents incorporated by reference, you
should carefully consider the following risk factors.

RISK FACTORS RELATING TO THE EXCHANGE OFFERS AND CONSENT SOLICITATIONS

  THE PROPOSED AMENDMENTS TO THE R&B FALCON INDENTURES WILL AFFORD REDUCED
  PROTECTION TO REMAINING HOLDERS OF R&B FALCON NOTES.

     If the proposed amendments to the R&B Falcon indentures are adopted, the
covenants and some other terms of the R&B Falcon notes will be less restrictive
and will afford reduced protection to holders of such securities compared to the
covenants and other provisions currently contained in the R&B Falcon indentures.
The proposed amendments to the R&B Falcon indentures would, among other things:

     - eliminate the covenants that restrict the ability of R&B Falcon and some
       of its subsidiaries to incur, issue, assume or guarantee indebtedness, if
       that indebtedness is secured by principal properties or securities of
       such subsidiaries, or enter into sale and leaseback transactions,

     - eliminate the covenants in the R&B Falcon 9.125% - 9.50% notes indenture
       that limit the ability of R&B Falcon to incur indebtedness and to make
       dividends and distributions (which covenants are currently suspended
       because R&B Falcon has an investment grade debt rating),

     - eliminate some requirements that must be met for R&B Falcon to
       consolidate, merge or sell all or substantially all of its assets,

     - eliminate some events from the definition of an "event of default" under
       the R&B Falcon notes indentures,

     - eliminate the covenant requiring R&B Falcon to prepare and file separate
       financial reports, and

     - eliminate the covenants requiring R&B Falcon to maintain its properties
       in good condition and repair, and to pay or discharge all material taxes,
       assessments and governmental charges and all claims which otherwise might
       become a material lien on the property of R&B Falcon or certain of its
       subsidiaries.

     If the proposed amendments are adopted with respect to the R&B Falcon
notes, each non-exchanging holder of R&B Falcon notes will be bound by the
proposed amendments even if that holder did not consent to the proposed
amendments. The elimination or modification of the covenants and other
provisions in the R&B Falcon indentures contemplated by the proposed amendments
would, among other things, permit Transocean Sedco Forex, R&B Falcon and their
respective subsidiaries to take actions that could increase the credit risk with
respect to R&B Falcon, and might adversely affect the liquidity, market price
and price volatility of the R&B Falcon notes or otherwise be adverse to the
interests of the holders of the R&B Falcon notes. See "The Proposed Amendments."

  THE LIQUIDITY OF THE R&B FALCON NOTES THAT ARE NOT EXCHANGED WILL BE REDUCED.

     The current trading market for the R&B Falcon notes is limited. The trading
market for unexchanged R&B Falcon notes will become more limited and could cease
to exist due to the reduction in the amount of the R&B Falcon notes outstanding
upon consummation of the exchange offers. A more limited trading market might
adversely affect the liquidity, market price and price volatility of these
securities. If a market for unexchanged R&B Falcon notes exists or

                                        14


develops, these securities may trade at a discount to the price at which the
securities would trade if the amount outstanding were not reduced, depending on
prevailing interest rates, the market for similar securities and other factors.
However, there can be no assurance that an active market in the unexchanged R&B
Falcon notes will exist, develop or be maintained or as to the prices at which
the unexchanged R&B Falcon notes may be traded.

  OUR HOLDING COMPANY STRUCTURE RESULTS IN STRUCTURAL SUBORDINATION AND MAY
  AFFECT OUR ABILITY TO MAKE PAYMENTS ON THE TRANSOCEAN SEDCO FOREX NOTES.

     The Transocean Sedco Forex notes are obligations exclusively of Transocean
Sedco Forex. We are a holding company and, accordingly, substantially all of our
operations are conducted through our subsidiaries. As a result, our cash flow
and our ability to service our debt, including the notes to be issued in the
exchange offers, is dependent upon the earnings of our subsidiaries and on the
distribution of earnings, loans or other payments by our subsidiaries to us. The
Transocean Sedco Forex notes offered will be structurally subordinated to all
obligations of Transocean Sedco Forex's subsidiaries, including any R&B Falcon
notes not properly tendered and accepted for payment in the exchange offers,
with respect to the assets of such subsidiaries. As of December 31, 2001, the
aggregate amount of outstanding long-term debt of Transocean Sedco Forex's
subsidiaries to which holders of the Transocean Sedco Forex notes would have
been structurally subordinated was approximately $1,783.9 million, of which
$1,537.9 million represented the carrying value of the six series of R&B Falcon
notes for which Transocean Sedco Forex is making the exchange offers. See
"Description of the Transocean Sedco Forex Notes -- Ranking; Additional Debt."

  A PUBLIC MARKET DOES NOT CURRENTLY EXIST FOR THE TRANSOCEAN SEDCO FOREX NOTES
  OFFERED IN THE EXCHANGE OFFERS, AND A MARKET MAY NOT DEVELOP OR BE SUSTAINED.

     Transocean Sedco Forex does not plan to list the Transocean Sedco Forex
notes offered under this prospectus and consent solicitation statement on any
national securities exchange or on The Nasdaq Stock Market. Although the R&B
Falcon notes are not so listed, there currently exists a limited trading market
for the R&B Falcon notes. The Transocean Sedco Forex notes will represent new
securities for which no such market currently exists. Although a market exists
for currently outstanding debt securities of Transocean Sedco Forex, there can
be no assurance that an active trading market for the Transocean Sedco Forex
notes offered under this prospectus and consent solicitation statement will
develop or, if such a market develops, that it will be liquid or sustainable.

  A RATINGS DECLINE COULD ADVERSELY AFFECT THE VALUE OF THE NOTES.

     Any of the agencies that rate our debt have the ability to lower the
ratings currently assigned to our debt, as a result of their views about our
current or future business, financial condition or results of operations. Any
ratings decline could adversely affect the value of the Transocean Sedco Forex
notes offered under this prospectus and consent solicitation statement.

RISK FACTORS RELATING TO THE BUSINESS OF TRANSOCEAN SEDCO FOREX

If any of the following risks occur, our business, financial condition or
results of operations could be materially adversely affected.

  OUR BUSINESS DEPENDS ON THE LEVEL OF ACTIVITY IN THE OIL AND GAS INDUSTRY,
  WHICH IS SIGNIFICANTLY AFFECTED BY OIL AND GAS PRICES, WHICH ARE OFTEN
  VOLATILE.

     Our business depends on the level of activity in oil and gas exploration,
development and production in markets worldwide, with the U.S. and international
offshore and U.S. inland marine areas being our primary markets. Oil and gas
prices and market expectations of potential changes in these prices
significantly affect this level of activity. Worldwide military, political and

                                        15


economic events have contributed to oil and gas price volatility and are likely
to do so in the future. Oil and gas prices are extremely volatile and are
affected by numerous factors, including the following:

     - worldwide demand for oil and gas,

     - the ability of the Organization of Petroleum Exporting Countries,
       commonly called "OPEC," to set and maintain production levels and
       pricing,

     - the level of production in non-OPEC countries,

     - the policies of various governments regarding exploration and development
       of their oil and gas reserves,

     - advances in exploration and development technology, and

     - the worldwide military and political environment, including uncertainty
       or instability resulting from an escalation or additional outbreak of
       armed hostilities or other crisis in the Middle East or other geographic
       areas in which we operate or further acts of terrorism in the United
       States, or elsewhere.

  OUR INDUSTRY IS HIGHLY COMPETITIVE AND CYCLICAL, WITH INTENSE PRICE
  COMPETITION AND PERIODS OF LOW DEMAND AND EXCESS RIG AVAILABILITY.

     The offshore and inland marine contract drilling industry is highly
competitive with numerous industry participants, none of which has a dominant
market share. Drilling contracts are traditionally awarded on a competitive bid
basis. Intense price competition is often the primary factor in determining
which qualified contractor is awarded a job, although rig availability and the
quality and technical capability of service and equipment may also be
considered. Recent mergers among oil and natural gas exploration and production
companies have reduced the number of available customers.

     Our industry has historically been cyclical and may be impacted by oil and
gas price levels and volatility. There have been periods of high demand, short
rig supply and high dayrates, followed by periods of low demand, excess rig
supply and low dayrates. Changes in commodity prices can have a dramatic effect
on rig demand, and periods of excess rig supply intensify the competition in the
industry and often result in rigs being idle for long periods of time. We may be
required to idle rigs or to enter into lower rate contracts in response to
market conditions in the future.

  THE LEVEL OF ACTIVITY IN THE OIL AND GAS INDUSTRY IS CURRENTLY RELATIVELY LOW
  IN MOST OF OUR MARKETS, WHICH ADVERSELY AFFECTS OUR DAYRATES AND RIG
  UTILIZATION.

     Decreases in U.S. natural gas prices since the beginning of the second
quarter 2001 led to a decline in our Gulf of Mexico shallow and inland water
segment utilization and dayrates and these conditions could continue or worsen.
In addition, reduced exploration and development spending by our customers in
response to lower oil and gas prices and consolidation activity among major oil
producers has resulted in lower utilization and dayrates for our drilling rigs.
Current market conditions have resulted in surplus rig capacity, particularly in
the lower specification semisubmersible and some jackup markets. We currently
believe that demand in early 2002 will generally decline for midwater rigs in
the Gulf of Mexico and North Sea markets and for jackup rigs in the Gulf of
Mexico market. If oil or gas prices remain at current levels or decline, demand
for our drilling services could be further reduced, which would adversely affect
both utilization and dayrates.

                                        16


  OUR DRILLING CONTRACTS MAY BE TERMINATED OR SUSPENDED DUE TO A NUMBER OF
  EVENTS.

     Our customers may terminate or suspend some of our term drilling contracts
under various circumstances such as the loss or destruction of the drilling unit
or as a result of equipment problems. Some drilling contracts permit the
customer to terminate the contract at the customer's option without paying a
termination fee. Suspension of drilling contracts results in loss of the dayrate
for the period of the suspension. If our customers cancel some of our
significant contracts and we are unable to secure new contracts on substantially
similar terms, it could adversely affect our results of operations. In reaction
to depressed market conditions, our customers may also seek renegotiation of
firm drilling contracts to reduce their obligations.

  WE MAY FACE DIFFICULTIES IN INTEGRATING OUR COMBINED OPERATIONS.

     We have been involved in two merger transactions in the last three years.
We may not be able to integrate the operations of the merged or acquired
companies without a loss of employees, customers or suppliers, a loss of
revenues, an increase in operating or other costs or other difficulties. In
addition, we may not be able to realize the operating efficiencies, synergies,
cost savings or other benefits expected from these transactions.

     We plan to continue our restructuring of the ownership of a portion of the
assets held by R&B Falcon and its subsidiaries at the time of our merger. This
restructuring is intended to achieve operational efficiencies, including
improved worldwide cash management and increased flexibility for operating rigs
in various jurisdictions, and allow for potential tax and other savings. Any
transfers of assets by R&B Falcon or one of its subsidiaries to Transocean Sedco
Forex or one of its other subsidiaries in this restructuring could, in some
cases, result in the imposition of additional taxes.

  OUR BUSINESS INVOLVES NUMEROUS OPERATING HAZARDS AND IT WILL NOT BE FULLY
  INSURED AGAINST ALL OF THEM.

     Our operations are subject to the usual hazards inherent in the drilling of
oil and gas wells, such as blowouts, reservoir damage, loss of production, loss
of well control, punchthroughs, craterings and fires. The occurrence of these
events could result in the suspension of drilling operations, damage to or
destruction of the equipment involved and injury or death to rig personnel. We
may also be subject to personal injury and other claims of rig personnel as a
result of our drilling operations. Operations also may be suspended because of
machinery breakdowns, abnormal drilling conditions, failure of subcontractors to
perform or supply goods or services or personnel shortages. In addition,
offshore drilling operators are subject to perils peculiar to marine operations,
including capsizing, grounding, collision and loss or damage from severe
weather. Damage to the environment could also result from our operations,
particularly through oil spillage or extensive uncontrolled fires. We may also
be subject to property, environmental and other damage claims by oil and gas
companies. Our insurance policies and contractual rights to indemnity may not
adequately cover losses, and we may not have insurance coverage or rights to
indemnity for all risks.

     If a significant accident or other event, including terrorist acts, war,
civil disturbances, pollution or environmental damage, occurs and is not fully
covered by insurance or a recoverable indemnity from a client, it could
adversely affect our consolidated financial position or results of operations.
Moreover, no assurance can be made that we will be able to maintain adequate
insurance in the future at rates we consider reasonable or be able to obtain
insurance against certain risks, particularly in light of the instability and
developments in the insurance markets following the recent terrorist attacks.
See "-- Recent terrorist attacks and United States military action could result
in a material adverse effect on our business" for further details.

                                        17


  OUR NON-U.S. OPERATIONS WILL INVOLVE ADDITIONAL RISKS NOT ASSOCIATED WITH OUR
  U.S. OPERATIONS.

     We operate in various regions throughout the world that may expose us to
political and other uncertainties, including risks of:

     - terrorist acts, war and civil disturbances,

     - expropriation or nationalization of equipment,

     - the inability to repatriate income or capital, and

     - changing taxation policies.

     Many governments favor or effectively require the awarding of drilling
contracts to local contractors or require foreign contractors to employ citizens
of, or purchase supplies from, a particular jurisdiction. These practices may
adversely affect our ability to compete.

     Our non-U.S. contract drilling operations are subject to various laws and
regulations in countries in which we operate, including laws and regulations
relating to the equipment and operation of drilling units, currency conversions
and repatriation, oil and gas exploration and development and taxation of
offshore earnings and earnings of expatriate personnel. Governments in some
foreign countries have become increasingly active in regulating and controlling
the ownership of concessions and companies holding concessions, the exploration
of oil and gas and other aspects of the oil and gas industries in their
countries. In addition, government action, including initiatives by OPEC, may
continue to cause oil or gas price volatility. In some areas of the world, this
governmental activity has adversely affected the amount of exploration and
development work done by major oil companies and may continue to do so.

     Another risk inherent in our operations is the possibility of currency
exchange losses where revenues are received and expenses are paid in foreign
currencies. We may also incur losses as a result of an inability to collect
revenues because of a shortage of convertible currency available to, or transfer
or exchange by, the country of operation.

  FAILURE TO RETAIN KEY PERSONNEL COULD HURT OUR OPERATIONS.

     We require highly skilled personnel to operate and provide technical
services and support for our drilling units. To the extent that demand for
drilling services and the size of the worldwide industry fleet increase,
shortages of qualified personnel could arise, creating upward pressure on wages.

     On a worldwide basis, we had approximately 11.3 percent of our employees
working under collective bargaining agreements as of December 31, 2001, most of
whom were working in Norway, Nigeria, Brazil and Venezuela. Of these represented
employees, a majority are working under agreements that are subject to salary
negotiation in 2002. In addition, the Company has signed a recognition agreement
requiring negotiation with a labor union representing employees in the U.K.
These negotiations are expected to begin in the second quarter of 2002 and could
result in collective bargaining agreements covering these employees, which could
result in higher personnel expenses, other increased costs or increased
operating restrictions.

  GOVERNMENTAL LAWS AND REGULATIONS MAY ADD TO OUR COSTS OR LIMIT DRILLING
  ACTIVITY.

     Our operations are affected from time to time in varying degrees by
governmental laws and regulations. The drilling industry is dependent on demand
for services from the oil and gas exploration industry and, accordingly, is also
affected by changing tax and other laws relating to the energy business
generally. We may be required to make significant capital expenditures to comply
with laws and regulations. It is also possible that these laws and regulations
may in the future add significantly to operating costs or may limit drilling
activity.

                                        18


  COMPLIANCE WITH OR BREACH OF ENVIRONMENTAL LAWS CAN BE COSTLY AND COULD LIMIT
  OUR OPERATIONS.

     Our operations are subject to regulations controlling the discharge of
materials into the environment, requiring removal and cleanup of materials that
may harm the environment or otherwise relating to the protection of the
environment. For example, as an operator of mobile offshore drilling units in
navigable United States waters and some offshore areas, we may be liable for
damages and costs incurred in connection with oil spills related to those
operations. Laws and regulations protecting the environment have become more
stringent in recent years, and may in some cases impose strict liability,
rendering a person liable for environmental damage without regard to negligence.
These laws and regulations may expose us to liability for the conduct of or
conditions caused by others or for acts that were in compliance with all
applicable laws at the time they were performed. The application of these
requirements or the adoption of new requirements could have a material adverse
effect on our financial position and results of our operations.

  OUR ADOPTION OF SFAS NO. 142 COULD ADVERSELY AFFECT EARNINGS.

     In July 2001, the FASB issued SFAS No. 142, Goodwill and Other Intangible
Assets, which became effective for fiscal years beginning after December 15,
2001. SFAS No. 142 prohibits amortization of goodwill and requires that goodwill
be tested at least annually for impairment. The statement also includes specific
guidance for testing goodwill impairment. We adopted SFAS No. 142 as of January
1, 2002. Our management is currently evaluating SFAS No. 142 and the impact of
implementing the required goodwill impairment test on our consolidated financial
position and results of operations. While we have not completed our evaluation,
we believe that there could be a charge to earnings in 2002 for impairment of
goodwill and that such charge could be significant.

  RECENT TERRORIST ATTACKS AND UNITED STATES MILITARY ACTION COULD RESULT IN A
  MATERIAL ADVERSE EFFECT ON OUR BUSINESS.

     On September 11, 2001, the United States was the target of terrorist
attacks of unprecedented scope. On October 7, 2001, the United States commenced
military action in Afghanistan in response to these attacks. Military action by
the United States may continue indefinitely and may escalate and armed
hostilities may begin or escalate in other countries. Further acts of terrorism
in the United States or elsewhere may occur, and such acts of terrorism could be
directed against companies such as ours. These developments have caused
instability in the world's financial and insurance markets and will likely
significantly increase political and economic instability in the geographic
areas in which we currently operate. In addition, these developments could lead
to increased volatility in prices for crude oil and natural gas and could affect
the markets for drilling services.

     Following the terrorist attacks on September 11, 2001, insurance
underwriters increased insurance premiums charged for many of the coverages
historically maintained and issued general notices of cancellations to their
customers for war risk, terrorism and political risk insurance in respect of a
wide variety of insurance coverages, including but not limited to, liability and
aviation coverages. Our insurance underwriters renegotiated substantially higher
premium rates for war risk coverage, which can be cancelled by the underwriters
on short notice. Insurance premiums could be increased further or coverages may
be unavailable in the future.

     United States government regulations effectively preclude us from actively
engaging in business activities in certain countries. These regulations could be
amended to cover countries where we currently operate or where we may wish to
operate in the future. These developments could subject the worldwide operations
of our company to increased risks and, depending on their magnitude, could have
a material adverse effect on our business.

          ENFORCEABILITY OF CIVIL LIABILITIES AGAINST FOREIGN PERSONS

     Transocean Sedco Forex is a Cayman Islands exempted company, and certain of
our officers and directors may be residents of various jurisdictions outside the
United States. All or a substantial portion of our assets and the assets of
these persons may be located outside the United States. As a result, it may be
difficult for investors to effect service of process within the United States
upon these persons or to enforce any United States court judgment obtained
against these persons that are predicated upon the civil liability provisions of
the Securities Act. We have agreed to be served with process with respect to
actions based on the exchange offers and consent solicitations. To bring a claim
against us, you may serve our Corporate Secretary,

                                        21


c/o Transocean Sedco Forex Inc., 4 Greenway Plaza, Houston, Texas 77046, our
United States agent appointed for that purpose.

     Walkers, our Cayman Islands legal counsel, has advised us that there is
doubt as to whether Cayman Islands courts would enforce (1) judgments of United
States courts obtained in actions against us or other persons that are
predicated on the civil liability provisions of the Securities Act or (2)
original actions brought against us or other persons predicated on the
Securities Act. There is no treaty between the United States and the Cayman
Islands providing for enforcement of judgments, and there are grounds upon which
Cayman Islands courts may not enforce judgments of United States courts. In

                              THE EXCHANGE OFFERS

PURPOSE OF THE EXCHANGE OFFERS

     Since the acquisition of R&B Falcon, Transocean Sedco Forex has been
operationally and financially integrating R&B Falcon into the Transocean Sedco
Forex organization. See "Certain Related Transactions" for a description of some
of these integration and restructuring transactions. The proposed amendments to
the R&B Falcon indentures are intended to provide greater operational and
financial flexibility, including greater flexibility in continuing our
integration and restructuring efforts, and to allow us to structure our
operations and the operations of our subsidiaries in a more efficient manner and
allow for potential savings. See "The Proposed Amendments."

     The principal amounts, interest rates, redemption terms and payment and

the exchange offers are the same as those of the corresponding series of R&B
Falcon notes. The Transocean Sedco Forex notes you receive in exchange for R&B
Falcon notes will accrue interest from the last date to which interest has been
paid on those R&B Falcon notes. You will not receive a payment for accrued
interest on R&B Falcon notes you exchange at the time of that exchange.

     The Transocean 6.50% notes, Transocean 6.75% notes, Transocean 6.95% notes,
Transocean 7.375% notes, Transocean 9.125% notes and Transocean 9.50% notes are

6.75% notes, R&B Falcon 6.95% notes and R&B Falcon 7.375% notes is referred to

                                        23


indenture for the R&B Falcon 9.125% notes and R&B Falcon 9.50% notes is referred
to as the "R&B Falcon 9.125%-9.50% notes indenture." The R&B Falcon 6.50%-7.375%
notes indenture and the R&B Falcon 9.125%-9.50% notes indenture are together
referred to as the "R&B Falcon indentures."


     Transocean Sedco Forex is also soliciting consents from the holders of each
series of R&B Falcon notes to effect a number of amendments to the R&B Falcon
indentures under which those notes were issued. For a description of the
proposed amendments, see "The Proposed Amendments." Transocean Sedco Forex's
obligation to complete each exchange offer and cause R&B Falcon to make the
consent payments relating to that exchange offer is conditioned on, among other
things, receipt of valid and unrevoked consents to the amendments from the
holders of record as of the close of business on February 13, 2002 (such time
and date being herein referred to as the "Record Date") of a majority in
principal amount of each of the six series of R&B Falcon notes (the "Consent
Condition"), although Transocean Sedco Forex will be free to waive this or any
other condition with respect to any or all of the exchange offers. A holder
validly tendering notes for exchange will, by tendering those notes, be
consenting to the proposed amendments to the indenture under which those notes
were issued.



     In addition to the Transocean Sedco Forex notes that Transocean Sedco Forex
will issue in exchange for R&B Falcon notes, R&B Falcon will pay an amount in
cash equal to the applicable consent payment listed on the cover page of this
prospectus and consent solicitation statement to each holder of R&B Falcon notes
accepted for exchange if the holder has tendered those notes prior to the
applicable consent payment deadline. The consent payment deadline for each
exchange offer (that is, the time by which holders must tender R&B Falcon notes
in that offer in order to be eligible to receive the consent payment) will be
Midnight, New York City time, on February 13, 2002, unless extended.


     R&B FALCON WILL MAKE A CONSENT PAYMENT FOR R&B FALCON NOTES IF AND ONLY IF
THE HOLDER OF THOSE NOTES TENDERS THOSE NOTES IN THE APPLICABLE EXCHANGE OFFER
PRIOR TO THE APPLICABLE CONSENT PAYMENT DEADLINE AND TRANSOCEAN SEDCO FOREX IN
FACT EXCHANGES THOSE NOTES FOR TRANSOCEAN SEDCO FOREX NOTES IN THAT EXCHANGE
OFFER.

     If the required consents are received with respect to each series of R&B
Falcon notes, then R&B Falcon and the trustee with respect to each series of the
R&B Falcon notes under the R&B Falcon indentures (the "R&B Falcon trustee") will
execute supplemental indentures setting forth the proposed amendments in respect
of all series. If the required consents are received with respect to one or
more, but not all, series of R&B Falcon notes and Transocean Sedco Forex waives
the condition that it receive consents to the proposed amendments to the R&B
Falcon indenture with respect to each series of R&B Falcon notes, then R&B
Falcon and the R&B Falcon trustee will execute a supplemental indenture setting
forth the proposed amendments in respect of the series as to which the required
consents are received. Under the terms of the supplemental indentures, the
amendments will not become operative with respect to a series of R&B Falcon
notes unless and until Transocean Sedco Forex exchanges all R&B Falcon notes of
that series validly tendered and not withdrawn for Transocean Sedco Forex notes
of the corresponding series pursuant to the applicable exchange offer, even if
all notes of that series that were validly tendered are withdrawn. Each
non-exchanging holder of that series of R&B Falcon notes will be bound by the
supplemental indenture.

               or prospects of Transocean Sedco Forex and its subsidiaries,

          (2) None of the following has occurred:

             - any material adverse change in United States securities or
               financial markets generally, or

             - in the case of any of the foregoing existing at the time of the
               commencement of the exchange offers, a material acceleration or
               worsening thereof; and

          (3) The R&B Falcon trustee has executed and delivered a supplemental
     indenture relating to the proposed amendments and has not objected in any

     Transocean Sedco Forex adversely affect the

                                        25


     consummation of, any of the exchange offers, the exchange of R&B Falcon
     notes under the exchange offers, the consent solicitations or Transocean
     Sedco Forex's ability to effect the proposed amendments, nor has the R&B
     Falcon trustee taken any action that challenges the validity or
     effectiveness of the procedures used by Transocean Sedco Forex in
     soliciting consents (including the form thereof) or in making the exchange
     offers, the exchange of the R&B Falcon notes under the exchange offers or
     the consent solicitations.

     All of these conditions are for the sole benefit of Transocean Sedco Forex
and may be waived by Transocean Sedco Forex, in whole or in part, and with
respect to the exchange offers for any or all series of R&B Falcon notes, in its
sole discretion. Any determination made by Transocean Sedco Forex concerning
these events, developments or circumstances shall be conclusive and binding.

     If any of these conditions are not satisfied with respect to a particular
series of R&B Falcon notes, Transocean Sedco Forex may, at any time before or
concurrently with the consummation of the exchange offer or consent solicitation
with respect to that series:

          (1) terminate the exchange offer and the consent solicitation with
     respect to that series of R&B Falcon notes and return all tendered R&B
     Falcon notes of that series to the holders thereof (whether or not it
     terminates the exchange offers and consent solicitations with respect to
     any or all other series of R&B Falcon notes),

          (2) modify, extend or otherwise amend the exchange offer and consent
     solicitation with respect to that series of R&B Falcon notes (whether or
     not it modifies, extends or otherwise amends the exchange offers and
     consent solicitations with respect to any or all other series of R&B Falcon
     notes) and retain all tendered R&B Falcon notes of that series and consents
     until the expiration date, as extended, of such exchange offer and consent
     solicitation, subject, however, to the withdrawal rights of holders (See
     "The Exchange Offers -- Withdrawal of Tenders and Revocation of
     Corresponding Consents" and "-- Consent Payment Deadline; Expiration Date;
     Extensions; Amendments"), or

          (3) waive the unsatisfied conditions with respect to such exchange
     offer and consent solicitation and accept all R&B Falcon notes of that
     series tendered and not previously withdrawn (whether or not it waives
     these conditions for the exchange offers and consent solicitations with
     respect to any or all other series of R&B Falcon notes).

CONSENT PAYMENT DEADLINE; EXPIRATION DATE; EXTENSIONS; AMENDMENTS


     For purposes of each of the consent solicitations, the term "consent
payment deadline" means Midnight, New York City time, on February 13, 2002,
subject to the right of Transocean Sedco Forex to extend that date and time for
any of the consent solicitations in its sole discretion (whether or not it
extends that date and time with respect to any or all other consent
solicitations), in which case the consent payment deadline shall be, with
respect to any such extended consent solicitation, the latest date and time to
which that consent payment deadline is extended.



     For purposes of each of the exchange offers, the term "expiration date"
means 5:00 p.m., New York City time, on March 1, 2002, subject to the right of
Transocean Sedco Forex to extend that date and time for any of the exchange
offers in its sole discretion, in which case the expiration date shall be, with
respect to any such extended exchange offer, the latest date and time to which
that exchange offer is extended.


     Transocean Sedco Forex reserves the right, in its sole discretion, to (1)
delay accepting any validly tendered R&B Falcon notes of any series, (2) extend
any or all of the exchange offers, or (3) terminate or amend any or all of the
exchange offers, by giving oral or written notice of such delay, extension,
termination or amendment to the exchange agent. Any such delay in acceptance,
extension, termination or amendment will be followed as promptly as practicable
by
                                        26


a public announcement thereof which, in the case of an extension, will be made
no later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled expiration date.

     Transocean Sedco Forex also reserves the right, in its sole discretion, to
provide a subsequent offering period of between three and 20 business days for
any or all of the exchange offers. If a subsequent offering period is provided,
all R&B Falcon notes validly tendered and not withdrawn prior to the expiration
date of the initial offering period will be accepted and exchanged for
Transocean Sedco Forex notes and we will make a public announcement of the
subsequent offering period no later than 9:00 a.m., New York City time, on the
next business day after the expiration date of the initial offering period.
Unless otherwise provided in the announcement of the subsequent offering period,
all R&B Falcon notes validly tendered during the subsequent offering period will
be promptly accepted and exchanged for the applicable series of Transocean Sedco
Forex notes as they are tendered. Unless otherwise provided in the announcement
of the subsequent offering period, holders of R&B Falcon notes will not have the
right to withdraw notes tendered during the subsequent offering period and no
consent payment will be made with respect to notes tendered during the
subsequent offering period.


     If the exchange offers are amended in a manner determined by Transocean
Sedco Forex to constitute a material change, Transocean Sedco Forex will
promptly disclose such amendment by means of a prospectus supplement that will
be distributed to holders of R&B Falcon Notes and Transocean Sedco Forex will
extend the exchange offers to a date five to ten business days after disclosing
the amendment, depending upon the significance of the amendment and the manner
of disclosure to the holders, if the exchange offers would otherwise have
expired during such five to ten business day period.


     Without limiting the manner in which Transocean Sedco Forex may choose to
make a public announcement of any delay, extension, amendment or termination of
any of the exchange offers and consent solicitations, Transocean Sedco Forex
will have no obligation to publish, advertise or otherwise communicate any such
public announcement other than by making a timely release to any appropriate
news agency, including the Dow Jones News Service.

EFFECT OF TENDER

     Any tender by a holder of any series of R&B Falcon notes that is not
withdrawn prior to the expiration date of the applicable exchange offer will
constitute a binding agreement between that holder and Transocean Sedco Forex,
and, if not withdrawn prior to the applicable consent payment deadline, a
consent to the proposed amendments, upon the terms and subject to the conditions
of that exchange offer and the letter of transmittal and consent. The acceptance
of an exchange offer by a tendering holder of any series of R&B Falcon notes
will constitute the agreement by that holder to deliver good and marketable
title to the tendered R&B Falcon notes, free and clear of all liens, charges,
claims, encumbrances, interests and restrictions of any kind.

ABSENCE OF DISSENTERS' RIGHTS

     Holders of the R&B Falcon notes do not have any appraisal or dissenters'
rights under New York law, the law governing the R&B Falcon indentures and the
R&B Falcon notes, or under the terms of the R&B Falcon indentures in connection
with the exchange offers and consent solicitations.

ACCOUNTING TREATMENT OF EXCHANGE OFFERS

     The exchange offers will be accounted for by Transocean Sedco Forex as an
exchange of debt under United States generally accepted accounting principles.
The Transocean Sedco Forex notes to be issued in the exchange offers will be
recorded at the same carrying value as the R&B Falcon notes. Accordingly,
Transocean Sedco Forex will recognize no gain or loss for accounting purposes
upon the consummation of the exchange offers. Transocean Sedco Forex will
amortize

                                        27


a portion of the expenses of the exchange offers over the term of the Transocean
Sedco Forex notes issued in the exchange offers.

ACCEPTANCE OF R&B FALCON NOTES FOR EXCHANGE; DELIVERY OF TRANSOCEAN SEDCO FOREX
NOTES AND CONSENT PAYMENTS

     Assuming the conditions to the exchange offers are satisfied or waived,
Transocean Sedco Forex will issue new notes in book-entry form and cause R&B
Falcon to make consent payments in exchange for R&B Falcon notes on the third
business day following the expiration date of the applicable exchange offer or
as soon as practicable after that date. We refer to the date on which we
exchange Transocean Sedco Forex notes for R&B Falcon notes pursuant to any
exchange offer as the "exchange date" for that exchange offer.

     Transocean Sedco Forex will be deemed to have accepted validly tendered R&B
Falcon notes of any series when, and if, Transocean Sedco Forex has given oral
or written notice thereof to the exchange agent. Subject to the terms and
conditions of the exchange offers, delivery of Transocean Sedco Forex notes and
consent payments for R&B Falcon notes of any series accepted by Transocean Sedco
Forex will be made by the exchange agent on the applicable exchange date upon
receipt of such notice. The exchange agent will act as agent for tendering
holders of the R&B Falcon notes for the purpose of receiving R&B Falcon notes
from and transmitting Transocean Sedco Forex notes and consent payments to such
holders. If any tendered R&B Falcon notes are not accepted for any reason set
forth in the terms and conditions of the exchange offers or if R&B Falcon notes
are withdrawn prior to the expiration of the applicable exchange offer, such
unaccepted or withdrawn R&B Falcon notes will be returned without expense to the
tendering holder as promptly as practicable after the expiration or termination
of the applicable exchange offer.

PROCEDURES FOR TENDERING

     If you hold R&B Falcon notes of any series and wish to have those notes
exchanged for Transocean Sedco Forex notes of the corresponding series, you must
validly tender (or cause the valid tender of) your R&B Falcon notes using the
procedures described in this prospectus and consent solicitation statement and
in the accompanying letter of transmittal and consent. The proper tender of R&B
Falcon notes will constitute an automatic consent to the proposed amendments to
the R&B Falcon indentures.

     The procedures by which you may tender or cause to be tendered R&B Falcon
notes will depend upon the manner in which you hold the R&B Falcon notes, as
described below.

TENDER OF R&B FALCON NOTES HELD THROUGH A NOMINEE

     If you are a beneficial owner of R&B Falcon notes that are held of record
by a custodian bank, depositary, broker, trust company or other nominee, and you
wish to tender R&B Falcon notes in any of the exchange offers, you should
contact the record holder promptly and instruct the record holder to tender the
R&B Falcon notes and deliver a consent on your behalf using one of the
procedures described below.

TENDER OF R&B FALCON NOTES HELD WITH DTC

     Pursuant to authority granted by The Depository Trust Company, or DTC, if
you are a DTC participant that has R&B Falcon notes credited to your DTC account
and thereby held of record by DTC's nominee, you may directly tender your R&B
Falcon notes and deliver a consent as if you were the record holder.
Accordingly, references herein to record holders include DTC participants with
R&B Falcon notes credited to their accounts. Within two business days after the
date of this prospectus and consent solicitation statement, the exchange agent
will establish accounts with respect to the R&B Falcon notes at DTC for purposes
of the exchange offers.
                                        28


     Any participant in DTC may tender R&B Falcon notes and deliver a consent to
the proposed amendments to the R&B Falcon indentures by effecting a book-entry
transfer of the R&B Falcon notes to be tendered in the applicable exchange
offer(s) into the account of the exchange agent at DTC and either (1)
electronically transmitting its acceptance of the applicable exchange offer
through DTC's Automated Tender Offer Program ("ATOP") procedures for transfer;
or (2) completing and signing the letter of transmittal and consent according to
the instructions and delivering it, together with any signature guarantees and
other required documents, to the exchange agent at its address on the back cover
page of this prospectus and consent solicitation statement, in either case
before the applicable exchange offer(s) expire(s).

     If ATOP procedures are followed, DTC will verify each acceptance
transmitted to it, execute a book-entry delivery to the exchange agent's account
at DTC and send an agent's message to the exchange agent. An "agent's message"
is a message, transmitted by DTC to and received by the exchange agent and
forming part of a book-entry confirmation, which states that DTC has received an
express acknowledgement from a DTC participant tendering R&B Falcon notes that
the participant has received and agrees to be bound by the terms of the letter
of transmittal and consent and that Transocean Sedco Forex and R&B Falcon may
enforce the agreement against the participant. DTC participants following this
procedure should allow sufficient time for completion of the ATOP procedures
prior to the expiration date of the applicable exchange offer.

     The letter of transmittal and consent (or facsimile thereof), with any
required signature guarantees, or (in the case of book-entry transfer) an
agent's message in lieu of the letter of transmittal and consent, and any other
required documents, must be transmitted to and received by the exchange agent
prior to the expiration date of the applicable exchange offer at one of its
addresses set forth on the back cover page of this prospectus and consent
solicitation statement. Delivery of such documents to DTC does not constitute
delivery to the exchange agent.

Transocean Sedco Forex notes for R&B Falcon notes tendered by a letter of

       any claims that such holder is entitled to receive additional principal
       or interest payments with respect to the R&B Falcon notes (other than as

       consent) or to participate in any redemption or defeasance of the R&B
       Falcon notes,

       of the date of tender, free and clear of all liens, charges, claims,

       lawful agent and attorney-in-fact of the holder with respect to any
       tendered R&B Falcon notes, with full powers of substitution and
       revocation (such power of attorney being deemed to be an irrevocable
       power coupled with an interest) to cause the R&B Falcon notes tendered to
       be assigned, transferred and exchanged in the applicable exchange offer.

     There is a single form of letter of transmittal and consent that you can
fill out for any series of R&B Falcon notes.

PROPER EXECUTION AND DELIVERY OF LETTER OF TRANSMITTAL AND CONSENT

     If you wish to participate in the exchange offers and consent
solicitations, delivery of your R&B Falcon notes, signature guarantees and other
required documents are your responsibility. Delivery is not complete until the
required items are actually received by the exchange agent. If you mail these
items, Transocean Sedco Forex recommends that you (1) use registered mail
properly insured with return receipt requested and (2) mail the required items
sufficiently in advance of the expiration date with respect to the applicable
exchange offer to allow sufficient time to ensure timely delivery.

     Except as otherwise provided below, all signatures on the letter of
transmittal and consent or a notice of withdrawal must be guaranteed by a
recognized participant in the Securities Transfer Agents Medallion Program, the
NYSE Medallion Signature Program or the Stock Exchange Medallion Program.
Signatures on the letter of transmittal and consent need not be guaranteed if:

     - the letter of transmittal and consent is signed by a participant in DTC
       whose name appears on a security position listing of DTC as the owner of
       the R&B Falcon notes and the portion entitled "Special Issuance and
       Payment Instructions" or "Special Delivery Instructions" on the letter of
       transmittal and consent has not been completed, or

     - the R&B Falcon notes are tendered for the account of an Eligible
       Institution. See Instruction 4 in the letter of transmittal and consent.

WITHDRAWAL OF TENDERS AND REVOCATION OF CORRESPONDING CONSENTS

     Tenders of R&B Falcon notes in connection with any of the exchange offers
may be withdrawn at any time prior to expiration of the applicable exchange
offer. Tenders of R&B Falcon notes may not be withdrawn at any time after
expiration. The valid withdrawal of tendered R&B Falcon notes prior to the
applicable consent payment deadline will be deemed to be a concurrent revocation
of the related consent to the proposed amendments to the applicable R&B Falcon
indenture. You may only revoke a consent by validly withdrawing the related R&B
Falcon notes prior to the consent payment deadline.

     Beneficial owners desiring to withdraw R&B Falcon notes previously tendered
should contact the DTC participant through which they hold their R&B Falcon
notes. In order to withdraw R&B Falcon notes previously tendered, a DTC
participant may, prior to the expiration date of the applicable exchange offer,
withdraw its instruction previously transmitted through ATOP by (1) withdrawing
its acceptance through ATOP, or (2) delivering to the exchange agent by mail,
hand delivery or facsimile transmission, notice of withdrawal of such
instruction. The notice of withdrawal must contain the name and number of the
DTC participant. Withdrawal of a prior instruction will be effective upon
receipt of such notice of withdrawal by the exchange agent. All signatures on a
notice of withdrawal must be guaranteed by a recognized participant in the
Securities Transfer Agents Medallion Program, the NYSE Medallion Signature
Program or the Stock Exchange Medallion Program, except that signatures on the
notice of withdrawal need not be guaranteed if the R&B Falcon notes being
withdrawn are held for the account of an Eligible Institution. A withdrawal of
an instruction must be executed by a DTC participant in the same manner as such
DTC participant's name appears on its transmission through ATOP to which

                                        30


such withdrawal relates. A DTC participant may withdraw a tender only if such
withdrawal complies with the provisions described in this paragraph.

     Withdrawals of tenders of R&B Falcon notes may not be rescinded and any R&B
Falcon notes withdrawn will thereafter be deemed not validly tendered for
purposes of any exchange offer. Properly withdrawn R&B Falcon notes, however,
may be retendered by following the procedures described above at any time prior
to expiration of the applicable exchange offer.

MISCELLANEOUS

     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of R&B Falcon notes in
connection with any exchange offer will be determined by Transocean Sedco Forex,
in its sole discretion, whose determination will be final and binding.
Transocean Sedco Forex reserves the absolute right to reject any or all tenders
not in proper form or the acceptance for exchange of which may, in the opinion
of counsel for Transocean Sedco Forex, be unlawful. Transocean Sedco Forex also
reserves the absolute right to waive any defect or irregularity in the tender of
any R&B Falcon notes in any exchange offer, and the interpretation by Transocean
Sedco Forex of the terms and conditions of its exchange offers (including the
instructions in the letter of transmittal and consent) will be final and binding
on all parties. None of Transocean Sedco Forex, R&B Falcon, the exchange agent,
the information agent, the dealer managers or any other person will be under any
duty to give notification of any defects or irregularities in tenders or incur
any liability for failure to give any such notification.

     Tenders of R&B Falcon notes involving any irregularities will not be deemed
to have been made until such irregularities have been cured or waived. R&B
Falcon notes received by the exchange agent in connection with any exchange
offer that are not validly tendered and as to which the irregularities have not
been cured or waived will be returned by the exchange agent to the DTC
participant who delivered such R&B Falcon notes by crediting an account
maintained at DTC designated by such DTC participant as promptly as practicable
after the expiration date of the applicable exchange offer or the withdrawal or
termination of the applicable exchange offer.

TRANSFER TAXES

     Transocean Sedco Forex will pay all transfer taxes, if any, applicable to
the transfer and sale of R&B Falcon notes to Transocean Sedco Forex in the
exchange offers. If transfer taxes are imposed for any other reason, the amount
of those transfer taxes, whether imposed on the registered holders or any other
persons, will be payable by the tendering holder. Other reasons transfer taxes
could be imposed include:

     - if Transocean Sedco Forex notes in book-entry form are to be registered
       in the name of any person other than the person signing the letter of
       transmittal and consent, or

     - if tendered R&B Falcon notes are registered in the name of any person
       other than the person signing the letter of transmittal and consent.

     If satisfactory evidence of payment of or exemption from those transfer
taxes is not submitted with the letter of transmittal and consent, the amount of
those transfer taxes will be billed directly to the tendering holder and/or
withheld from any payments due with respect to the R&B Falcon notes tendered by
such holder.

U.S. FEDERAL BACKUP WITHHOLDING; WITHHOLDING ON CONSENT PAYMENTS TO NON-U.S.
HOLDERS

     U.S. federal income tax law requires that a holder of R&B Falcon notes,
whose notes are accepted for exchange, provide the exchange agent, as payer,
with the holder's correct taxpayer identification number or otherwise establish
a basis for an exemption from backup withholding. This information should be
provided on Internal Revenue Service (IRS) Form W-9. In the case of
                                        31


a holder who is an individual, other than a resident alien, this identification
number is his or her social security number. For holders other than individuals,
the identification number is an employer identification number. Exempt holders,
including, among others, all corporations and certain foreign individuals, are
not subject to these backup withholding and reporting requirements, but must
establish that they are so exempt. If you do not provide the exchange agent with
your correct taxpayer identification number or an adequate basis for an
exemption or a completed IRS Form W-8BEN ("Certificate of Foreign Status of
Beneficial Owner for United States Tax Withholding"), you may be subject to
backup withholding on payments made in exchange for any R&B Falcon notes and a
penalty imposed by the IRS. Backup withholding is not an additional federal
income tax. Rather, the amount of tax withheld will be credited against the
federal income tax liability of the holder subject to backup withholding. If
backup withholding results in an overpayment of taxes, you may obtain a refund
from the IRS. You should consult with a tax advisor regarding qualifications for
exemption from backup withholding and the procedure for obtaining the exemption.

     To prevent backup withholding, you must either (1) provide a completed IRS
Form W-9 and indicate either (a) your correct taxpayer identification number, or
(b) an adequate basis for an exemption, or (2) provide a completed Form W-8BEN.

     In compliance with U.S. federal withholding tax requirements applicable to
payments of certain U.S. source income to foreign persons, R&B Falcon intends to
withhold tax at the rate of 30% on consent payments made to non-U.S. holders,
unless the holder establishes an exemption or a reduced rate. See "Material U.S.
Federal Income Tax Consequences -- Non-U.S. Holders -- Consent Payments."

R&B Falcon notes if the Consent Condition is satisfied and the exchange offers
are completed. If the Consent Condition is not satisfied or the exchange offer
related to any of the six series of R&B Falcon notes is not completed,

                                        32


Transocean Sedco Forex will pay the dealer managers the same customary
percentage of the total principal amount of R&B Falcon notes tendered and
accepted for exchange by Transocean Sedco Forex pursuant to the exchange offers.
Transocean Sedco Forex will also reimburse the dealer managers for certain
expenses. The obligations of the dealer managers to perform such function are

federal securities laws. Questions regarding the terms of the exchange offers or
the consent solicitations may be directed to the dealer managers at the address

however, additional solicitations may be made by facsimile transmission,
telephone or in person by the dealer managers and the information agent, as well
as by officers and other employees of Transocean Sedco Forex and its affiliates.

     Tendering holders of R&B Falcon notes will not be required to pay any fee
or commission to the dealer managers. However, if a tendering holder handles the
transaction through its broker, dealer, commercial bank, trust company or other
institution, such holder may be required to pay brokerage fees or commissions.

                       DESCRIPTION OF DIFFERENCES BETWEEN
           THE R&B FALCON NOTES AND THE TRANSOCEAN SEDCO FOREX NOTES

     The following is a summary comparison of the material terms of the R&B
Falcon notes (four series of which were issued under the R&B Falcon 6.50%-7.375%
notes indenture and two series of which were issued under the R&B Falcon
9.125%-9.50% notes indenture) and the Transocean Sedco Forex notes. Each series
of the Transocean Sedco Forex notes issued in the exchange offers will be
governed by the Transocean Sedco Forex indenture. The summary does not purport
to be complete and is qualified in its entirety by reference to the R&B Falcon
indentures and the Transocean Sedco Forex indenture. Copies of those indentures
have been filed as exhibits to the registration statement of which this
prospectus and consent solicitation statement forms a part and are available
from the information agent upon request. See "Where You Can Find More
Information" for information as to how you can obtain a copy of the indentures
from the SEC.

     The R&B Falcon notes represent, as of the date of this prospectus and
consent solicitation statement, the only debt securities issued under the R&B
Falcon indentures.

     Capitalized terms used in the descriptions of the R&B Falcon notes and the
Transocean Sedco Forex notes below and not otherwise defined in this prospectus
and consent solicitation statement have the meanings given to such terms in the
R&B Falcon 6.50%-7.375% notes indenture, the R&B Falcon 9.125%-9.50% notes
indenture and the Transocean Sedco Forex indenture, respectively. For purposes
of the description of the R&B Falcon notes, the term "R&B Falcon" refers to R&B
Falcon Corporation (and any successor person or entity, as provided in the R&B
Falcon indentures), but does not include its subsidiaries. For purposes of the
description of the Transocean Sedco Forex notes, the term "Transocean Sedco
Forex" refers to Transocean Sedco Forex Inc. (and any successor person or
entity, as provided in the Transocean Sedco Forex indenture), but does not
include its subsidiaries. Section references in the descriptions of the notes
below are references to the applicable indenture under which the notes were or
will be issued.

     The description of the R&B Falcon notes reflects the R&B Falcon notes as
currently constituted and does not reflect any changes to the covenants and
other terms of the R&B Falcon notes or the R&B Falcon indentures that may be
effected following the consent solicitations as described under "The Proposed
Amendments."

LIMITATION ON INDEBTEDNESS IN THE R&B FALCON 9.125%-9.50% NOTES INDENTURE

     The provision described below is contained only in the R&B Falcon
9.125%-9.50% notes indenture. In the event that at any time (1) the ratings
assigned to the notes by both Moody's and Standard & Poor's are both investment
grade ratings and (2) no default has occurred and is continuing under the R&B
Falcon 9.125%-9.50% notes indenture, R&B Falcon and its Restricted Subsidiaries
will no longer be subject to the provision of the R&B Falcon 9.125%-9.50% notes
indenture described below, so long as the investment grade ratings are
maintained. R&B Falcon presently maintains an investment grade rating.
Therefore, the provision described below is currently suspended.

     R&B Falcon covenants under the R&B Falcon 9.125%-9.50% notes indenture that
it will not, and will not permit any Restricted Subsidiary to, incur, directly
or indirectly, any indebtedness unless its pro forma consolidated EBITDA
coverage ratio at the date of such incurrence exceeds 2.25 to 1.0.

     Incurrence of the following indebtedness is not restricted by this
covenant:

     - Indebtedness of R&B Falcon pursuant to its credit facilities, and the
       guarantee of this indebtedness by Restricted Subsidiaries, that the
       aggregate amount of this indebtedness outstanding does not exceed $350
       million.

     - Indebtedness of R&B Falcon or a Restricted Subsidiary owed to and held by
       a Restricted Subsidiary or indebtedness of a Restricted Subsidiary owed
       to and held by R&B Falcon. However, any subsequent issuance or transfer
       of any capital stock that results in the Restricted Subsidiary to whom
       indebtedness is owed ceasing to be a Restricted Subsidiary or any
       transfer of the indebtedness (other than to R&B Falcon or another
       Restricted Subsidiary) will be deemed, in each case, to constitute the
       incurrence of such indebtedness.

     - The R&B Falcon notes and indebtedness incurred in exchange for, or the
       proceeds of which are used to refund or refinance, any indebtedness
       permitted by these provisions if (1) the principal amount of the
       indebtedness so incurred does not exceed the principal amount of the
       indebtedness so exchanged, refunded or refinanced (plus the amount of
       reasonable related fees and expenses, including any premium or defeasance
       costs) and (2) the indebtedness so incurred (A) does not mature prior to
       the stated maturity of the indebtedness so exchanged, refunded or
       refinanced and (B) has an average life equal to or greater than the
       remaining average life of the indebtedness so exchanged, refunded or
       refinanced.

     - Indebtedness of R&B Falcon or any Restricted Subsidiary (other than
       indebtedness described in the first three bullet points above) (1)
       outstanding on the issue date or incurred pursuant to agreements as in
       effect on the issue date and (2) indebtedness incurred in exchange for,
       or the proceeds of which are used to refund or refinance, any
       indebtedness permitted by this provision or permitted by the provision
       described in the first bullet point above; if (A) the principal amount of
       the indebtedness so incurred does not exceed the principal amount of the
       indebtedness so exchanged, refunded or refinanced (plus the amount of
       reasonable related fees and expenses, including any premium or defeasance
       costs); and (B) the indebtedness so incurred (i) does not mature prior to
       the stated maturity of the indebtedness so exchanged, refunded or
       refinanced and (ii) has an average life equal to or greater than the
       remaining average life of the indebtedness so exchanged, refunded or
       refinanced.

     - Indebtedness of R&B Falcon or any Restricted Subsidiary consisting of
       guarantees in connection with any synthetic lease obligations of persons
       incurred to finance the construction or upgrade of the drillship
       Deepwater Frontier and the drillship Pathfinder pursuant to agreements
       governing such obligations.
                                        46


     - Acquired indebtedness of any Restricted Subsidiary in an aggregate amount
       not to exceed $300 million, if R&B Falcon on a pro forma basis could
       incur $1.00 of additional indebtedness pursuant to the EBITDA coverage
       ratio test of this covenant.

     - Indebtedness of R&B Falcon or any Restricted Subsidiary consisting of
       guarantees, indemnities or obligations in respect of purchase price
       adjustments in connection with the acquisition or disposition of assets,
       including shares of capital stock.

     - The incurrence by R&B Falcon's unrestricted Subsidiaries of non-recourse
       indebtedness. If any of this indebtedness ceases to be non-recourse
       indebtedness of any unrestricted Subsidiary, this event will be deemed to
       constitute an incurrence of indebtedness by a Restricted Subsidiary of
       R&B Falcon that was not permitted by this provision.

     - Obligations of R&B Falcon or a Restricted Subsidiary under performance or
       surety bonds relating to building contracts for the construction of
       drilling rigs, drillships or similar vessels or contracts for the
       installation of related equipment.

     - Hedging obligations.

     - Indebtedness of R&B Falcon or any Restricted Subsidiary in an aggregate
       principal amount which, together with all other indebtedness of R&B
       Falcon then outstanding (other than indebtedness permitted by the
       preceding bullet points) does not exceed $50 million;

R&B Falcon is not permitted to issue any indebtedness if the proceeds are used,
directly or indirectly, to repay, prepay, redeem, defease, retire, refund or
refinance any subordinated obligations unless such indebtedness will be
subordinated to the R&B Falcon notes to at least the same extent as the
subordinated obligations.

LIMITATION ON RESTRICTED PAYMENTS IN THE R&B FALCON 9.125%-9.50% NOTES INDENTURE

     The provision described below is contained only in the R&B Falcon
9.125%-9.50% notes indenture. In the event that at any time (1) the ratings
assigned to the notes by both Moody's and Standard & Poor's are both investment
grade ratings and (2) no default has occurred and is continuing under the R&B
Falcon 9.125%-9.50% notes indenture, R&B Falcon and its Restricted Subsidiaries
will no longer be subject to the provision of the R&B Falcon 9.125%-9.50% notes
indenture described below, so long as the investment grade ratings are
maintained. R&B Falcon presently maintains an investment grade rating.
Therefore, the provision described below is currently suspended.

     R&B Falcon covenants under the R&B Falcon 9.125%-9.50% notes indenture that
it will not, and will not permit any Restricted Subsidiary, directly or
indirectly, to declare or pay any dividend or make any distribution on or in
respect of its capital stock (including any payment in connection with any
merger or consolidation involving R&B Falcon) or to the direct or indirect
holders of its capital stock:

     - purchase, redeem or otherwise acquire or retire for value any capital
       stock of R&B Falcon or of any direct or indirect parent of R&B Falcon, or
       any Restricted Subsidiary, except capital stock held by R&B Falcon or a
       Restricted Subsidiary,

     - purchase, repurchase, redeem, defease or otherwise acquire or retire for
       value, prior to scheduled maturity, scheduled repayment or scheduled
       sinking fund payment, any subordinated obligations, other than the
       purchase, repurchase or other acquisition of subordinated obligations
       purchased in anticipation of satisfying a sinking fund obligation,
       principal installment or final maturity, in each case due within one year
       of the date of acquisition,

     - make certain investments,

                                        47


(any such dividend, distribution, purchase, redemption, repurchase, defeasance,
other acquisition, retirement or investment being herein referred to as a
"Restricted Payment") if at the time R&B Falcon or such Restricted Subsidiary
makes such Restricted Payment:

     - a default has occurred and is continuing (or would result from the
       Restricted Payment), or

     - R&B Falcon would not be permitted to incur an additional $1.00 of
       indebtedness pursuant to the EBITDA coverage ratio test of the limitation
       on indebtedness covenant in the R&B Falcon 9.125%-9.50% notes indenture
       after giving pro forma effect to such Restricted Payment, or

     - the aggregate amount of the Restricted Payment and all other Restricted
       Payments since the date on which the R&B Falcon notes were originally
       issued would exceed the sum of:

        - 50% of its consolidated net income accrued during the period, treated
          as one accounting period, from the beginning of the fiscal quarter
          during which the R&B Falcon notes were originally issued to the end of
          the most recent fiscal quarter ending at least 45 days prior to the
          date of the Restricted Payment or, in case the consolidated net income
          is a deficit, minus 100% of such deficit,

        - 100% of the aggregate net proceeds (including the fair market value of
          non-cash proceeds, which are to be determined in good faith by the
          Board of Directors of R&B Falcon) received by R&B Falcon from the
          issue or sale of its capital stock (other than redeemable stock or
          exchangeable stock) subsequent to the issue date, other than an
          issuance or sale to a Restricted Subsidiary or an employee stock
          ownership plan or similar trust,

        - the amount by which indebtedness of R&B Falcon is reduced on R&B
          Falcon's balance sheet upon the conversion or exchange (other than by
          a Restricted Subsidiary) subsequent to the incurrence of any
          indebtedness of R&B Falcon convertible or exchangeable for capital
          stock (other than redeemable stock or exchangeable stock) of R&B
          Falcon, less the amount of any cash, or other property, distributed by
          R&B Falcon upon such conversion or exchange,

        - to the extent not otherwise included in consolidated net income, the
          net reduction in investments in unrestricted Subsidiaries resulting
          from dividends, repayments of loans or advances, or other transfers of
          assets, in each case to R&B Falcon or any Restricted Subsidiary after
          the issue date from any unrestricted Subsidiary or from the
          redesignation of an unrestricted Subsidiary as a Restricted
          Subsidiary, not to exceed in the case of any Restricted Subsidiary the
          total amount of investments (other than investments permitted under
          the terms of the R&B Falcon 9.125%-9.50% notes indenture) in such
          Restricted Subsidiary made by R&B Falcon and its Restricted
          Subsidiaries in such unrestricted Subsidiary after the issue date, and

        - $20 million.

     The provisions of this section do not prohibit:

     - any dividends or distributions payable solely in its non-convertible
       capital stock or in options, warrants or other rights to purchase its
       non-convertible capital stock,

     - any dividends or distributions payable to R&B Falcon or a Restricted
       Subsidiary,

     - any pro rata dividends or distributions on the capital stock of a
       Restricted Subsidiary held by minority stockholders, including minority
       stockholders of Arcade Drilling AS, a Norwegian corporation,

     - any purchase or redemption of capital stock or subordinated obligations
       of R&B Falcon made by exchange for, or out of the proceeds of the
       substantially concurrent sale of,

                                        48


       capital stock of R&B Falcon (other than redeemable stock or exchangeable
       stock and other than capital stock issued or sold to a Restricted
       Subsidiary or an employee stock ownership plan). The purchase or
       redemption will be excluded in the calculation of the amount of
       Restricted Payments and the net cash proceeds from the sale will be
       excluded from any calculation of aggregate net proceeds from the sale of
       capital stock and the calculation of the reduction of indebtedness on R&B
       Falcon's balance sheet for indebtedness convertible into capital stock
       mentioned in "Limitations on Indebtedness in the R&B Falcon 9.125%-9.50%
       Notes Indenture",

     - any purchase or redemption of subordinated obligations of R&B Falcon made
       by exchange for, or out of the proceeds of the substantially concurrent
       sale of, indebtedness of R&B Falcon which is permitted to be issued
       pursuant to the provisions of Section 3.09 of the R&B Falcon 9.125%-9.50%
       notes indenture, "Limitations on Indebtedness." The purchase or
       redemption will be excluded in the calculation of the amount of
       Restricted Payments, or

     - any dividends paid within 60 days after the date of declaration if at the
       date of declaration the dividend would have complied with this provision;
       if at the time of payment of the dividend, no other default has occurred
       and is continuing (or would result from the dividend). The dividend shall
       be included in the calculation of the amount of Restricted Payments.

     Transocean Sedco Forex is proposing to delete the following covenants from
the R&B Falcon indenture for the 6.50%, 6.75%, 6.95% and 7.375% R&B Falcon
notes:

          (1) The covenant in Section 3.03 entitled "SEC Reports; Financial
     Statements," which is described above under "Description of Differences
     Between the R&B Falcon Notes and the Transocean Sedco Forex
     Notes -- Provision of Financial Information." In this regard, Transocean

     application (on Form 15) to the SEC to deregister the R&B Falcon common
     stock under the Securities Exchange Act of 1934, as amended. As a result of
     such deregistration and the effectiveness of the proposed amendments, R&B
     Falcon will no longer be obligated to file periodic reports with the SEC or
     deliver periodic reports to the holders of R&B Falcon debt.

          (2) The covenant in Section 3.05 entitled "Corporate Existence." Under
     Section 3.05, R&B Falcon covenants to preserve its corporate existence and
     the corporate, partnership or other existence of its subsidiaries.

          (3) The covenant in Section 3.06 entitled "Maintenance of Properties."
     Under Section 3.06, R&B Falcon covenants to maintain in good condition,
     repair and working order all properties owned or leased or used in the
     conduct of its business or the business of any subsidiary.

          (4) The covenant in Section 3.07 entitled "Payment of Taxes and Other
     Claims." Under Section 3.07, R&B Falcon covenants to pay or discharge,
     before the same become delinquent, (a) all material taxes, assessments and
     governmental charges levied or imposed upon R&B Falcon or any subsidiary or
     upon the income, profits or property of R&B Falcon or any subsidiary, and
     (b) all lawful claims for labor, materials and supplies which, if unpaid,
     might by law become a lien upon the property of R&B Falcon or any
     subsidiary.

          (5) The covenant in Section 3.09 entitled "Limitation on

     Substituted." Under Section 4.02, the successor to a consolidation, merger
     or sale of substantially all of the assets of R&B Falcon succeeds to R&B

     In conjunction with the deletion of the covenants identified above,

indenture, which are used only in those covenants or in other defined terms
being deleted: "Attributable Indebtedness," "Consolidated Net Worth,"
"Indebtedness," and "Sale/Leaseback Transactions".

     Transocean Sedco Forex is also requesting a waiver with respect to any
default, event of default or other consequence under the R&B Falcon indenture of
failing to comply with the terms of the covenants identified above (whether
before or after the date of the supplemental indenture) and to delete clauses
(4), (5), (6) and (7) from the definition of "Event of Default" in Section 5.01,
"Events of Default." These clauses provide, respectively, that each of the
following constitutes an "event of default":

     - a default that results in the acceleration of any debt of R&B Falcon or

       debtors, commences to a voluntary case, consents to the entry of an order
       for relief against it in an involuntary case, consents to the appointment
       of a receiver, trustee, assignee, liquidator or similar official under
       bankruptcy law for it or for all or a substantial part of its property,
       or makes a general assignment for the benefit of its creditors, and

     - a court of competent jurisdiction enters an order or decree under Title
       11, U.S. Code or any similar federal, state or foreign law for the relief
       of debtors that remains unstayed and in effect for 60 days and that is
       for relief against R&B Falcon, any guarantor under the indenture, or any
       significant subsidiary of R&B Falcon; appoints a receiver, trustee,
       assignee, liquidator or similar official under bankruptcy law for or for

     Substituted." Under Section 4.02, the successor to a merger, consolidation
     or sale of substantially all of the assets of R&B Falcon succeeds to R&B
     Falcon's obligations under the R&B Falcon indenture.

     In conjunction with the deletion of the covenants identified above,
Transocean Sedco Forex is proposing to delete the following defined terms in the
indenture, which are used only in those covenants or in other defined terms
being deleted: "Attributable Indebtedness"; "Consolidated EBITDA Coverage
Ratio"; "Consolidated Net Income"; "Consolidated Net Worth"; "Hedging
Obligations"; "Incurrence"; "Indebtedness"; "Restricted Subsidiary";
"Sale/Leaseback Transactions"; and "Suspended Covenants". In addition,
Transocean Sedco Forex is proposing to delete Section 3.13 entitled "Covenant
Termination." Under Section 3.13, the covenants in Section 3.09, "Limitation on
Indebtedness," and 3.12, "Limitation on Restricted Payments," are suspended
while the 9.125% and 9.50% R&B Falcon notes are rated investment grade by
Moody's and Standard & Poor's.

                                        52


     Transocean Sedco Forex is also requesting a waiver with respect to any
default, event of default or other consequence under the R&B Falcon indenture of
failing to comply with the terms of the covenants identified above (whether
before or after the date of the supplemental indenture) and to delete clauses
(4), (5), (6) and (7) from the definition of "Event of Default" in Section 5.01,
"Events of Default." These clauses provide, respectively, that each of the
following constitutes an "event of default":

     - a default that results in the acceleration of any debt of R&B Falcon or
       any of its subsidiaries having an outstanding principal amount of $20
       million or more, either individually or in the aggregate with other debt
       that has been accelerated,

     - a final judgment or order for payment of money in excess of $20 million
       is rendered against R&B Falcon, any guarantor under the indenture, or any
       "significant subsidiary" (as such term is defined in Regulation X under
       the Securities Exchange Act of 1934, as amended) of R&B Falcon and such
       judgment or order continues unsatisfied and unstayed for a period of 60
       days,

     - R&B Falcon, any guarantor under the indenture, or any significant
       subsidiary of R&B Falcon, pursuant to or within the meaning of Title 11,
       U.S. Code or any similar federal, state or foreign law for the relief of
       debtors, commences to a voluntary case, consents to the entry of an order
       for relief against it in an involuntary case, consents to the appointment
       of a receiver, trustee, assignee, liquidator or similar official under
       bankruptcy law for it or for all or a substantial part of its property,
       or makes a general assignment for the benefit of its creditors, and

     - a court of competent jurisdiction enters an order or decree under Title
       11, U.S. Code or any similar federal, state or foreign law for the relief
       of debtors that remains unstayed and in effect for 60 days and that is
       for relief against R&B Falcon, any guarantor under the indenture, or any
       significant subsidiary of R&B Falcon; appoints a receiver, trustee,
       assignee, liquidator or similar official under bankruptcy law for or for
       all or a substantial part of the property of R&B Falcon, any guarantor
       under the indenture, or any significant subsidiary of R&B Falcon, or
       orders the liquidation of, R&B Falcon, any guarantor under the indenture
       or any significant subsidiary of R&B Falcon.

                                        53


                          CERTAIN RELATED TRANSACTIONS

     R&B Falcon is a party to a $1.8 billion two-year revolving credit agreement
with Transocean Sedco Forex, dated April 6, 2001. Amounts outstanding under the
revolver bear interest payable quarterly at a rate of the London Interbank
Offered Rate plus 0.575 percent to 1.300 percent depending on R&B Falcon's
non-credit enhanced senior unsecured public debt rating. The amount currently
outstanding under the revolver is less than $1 million.

     A subsidiary of Transocean Sedco Forex provides administrative support
services to R&B Falcon. Transocean Sedco Forex charges R&B Falcon a proportional
share of its administrative costs based on estimates of the percentage of work
the individual Transocean Sedco Forex departments perform for R&B Falcon. In the
opinion of management, R&B Falcon is being charged for all costs incurred on its
behalf by Transocean Sedco Forex under a comprehensive and reasonable cost
allocation method.

     In August 2001, R&B Falcon and one of its subsidiaries sold, in separate
transactions, the Jack Bates, Deepwater Millennium, Deepwater Expedition,
Peregrine I, Deepwater Horizon, C. Kirk Rhein, Falcon 100, Deepwater Navigator
and Deepwater Discovery to Transocean Offshore International Ventures Limited
("TOIVL"). In consideration for the sales of these drilling units, $1.2 billion
of debt owed by R&B Falcon to Transocean Sedco Forex was cancelled. In addition,
TOIVL delivered promissory notes due August 17, 2011 bearing interest at 5.72
percent per annum and in the aggregate principal amount of $425.0 million. At
the time of the sales, each of the drilling units was being utilized in
connection with a drilling contract between a subsidiary of R&B Falcon and a
customer. These contracts were not transferred and R&B Falcon and its
subsidiaries secured the use of the drilling units for the purpose of performing
these contracts through charters or other arrangements.

     During 2001, Transocean Sedco Forex or its subsidiaries acquired $10.5
million in total principal amount of the 6.50% R&B Falcon Notes and $12.9
million in total principal amount of the 9.125% R&B Falcon notes. These notes
have been retired.

                                        54


                DESCRIPTION OF THE TRANSOCEAN SEDCO FOREX NOTES

     If the exchange offers are consummated, each series of the Transocean Sedco
Forex notes to be issued in exchange for the R&B Falcon notes will be issued
under an indenture, dated as of April 15, 1997, as amended, with the Bank of New
York as successor trustee to The Chase Manhattan Bank (the "Transocean Sedco
Forex trustee"). The Transocean Sedco Forex indenture, as supplemented, will for
purposes of the following description of the Transocean Sedco Forex notes, be
referred to as the "Transocean Sedco Forex indenture." The Transocean Sedco
Forex notes will be issued only in book-entry form in denominations of $1,000
and integral multiples of $1,000.

     The following summary of certain provisions of the Transocean Sedco Forex
indenture does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, the Trust Indenture Act of 1939, as amended (the
"Trust Indenture Act"), and to all of the provisions of the Transocean Sedco
Forex indenture, including the definitions of certain terms in the Transocean
Sedco Forex indenture and those terms made a part of the Transocean Sedco Forex
indenture by reference to the Trust Indenture Act as in effect on the date of
the Transocean Sedco Forex indenture. The Transocean Sedco Forex indenture is,
by its terms, subject to and governed by the Trust Indenture Act.

     For purposes of the following description of the Transocean Sedco Forex
notes, the terms "Transocean Sedco Forex" and "we" or "our" refers to Transocean
Sedco Forex Inc. (and any successor person or entity, as provided in the
Transocean Sedco Forex indenture), but does not include its subsidiaries.

     A copy of the Transocean Sedco Forex indenture may be obtained from the
information agent and is also filed as an exhibit to the registration statement

principal amounts less than the amounts described above if less than all
outstanding R&B Falcon notes are validly tendered and not withdrawn in the
exchange offers.

RANKING; ADDITIONAL DEBT

     The Transocean Sedco Forex notes will be our unsecured obligations. The
Transocean Sedco Forex notes will rank equal in right of payment with all of our
other unsecured and unsubordinated indebtedness. The Transocean Sedco Forex
indenture does not limit the amount of debt that we or any of our subsidiaries
may incur or issue, nor does it restrict transactions between us and our
affiliates or dividends and other distributions by us or our subsidiaries. We
may issue debt securities under the Transocean Sedco Forex indenture from time
to time in separate series, each up to the aggregate amount we authorize from
time to time for that series.

     The Transocean Sedco Forex notes offered will be structurally subordinated
to all obligations of Transocean Sedco Forex's subsidiaries, including any R&B
Falcon notes not properly tendered and accepted for payment in the exchange
offers, with respect to the assets of such subsidiaries. As of December 31,
2001, the aggregate amount of outstanding long-term debt of Transocean Sedco
Forex's subsidiaries to which holders of the Transocean Sedco Forex notes would
have been structurally subordinated was approximately $1,783.9 million, of which
$1,537.9 million represented the carrying value of the six series of R&B Falcon
notes for which Transocean Sedco Forex is making the exchange offers. See "Risk
Factors -- Risks Relating to the Exchange Offers and Consent Solicitation
Statement -- Our holding company structure results in

                                        56


substantial structural subordination and may affect our ability to make payments
on the Transocean Sedco Forex notes."

OPTIONAL REDEMPTION

     The 6.50% Transocean Sedco Forex notes are not redeemable.

     The 6.75% Transocean Sedco Forex notes, the 6.95% Transocean Sedco Forex
notes, the 7.375% Transocean Sedco Forex notes, the 9.125% Transocean Sedco
Forex notes and the 9.50% Transocean Sedco Forex notes are redeemable, at our
option, at any time in whole or from time to time in part upon not less than 30
and not more than 60 days' notice mailed to each holder of Transocean Sedco
Forex notes of such series to be redeemed at the holder's address appearing in
the security register, on any date prior to maturity at a price equal to 100% of
the principal amount thereof plus accrued and unpaid interest to the redemption
date (subject to the right of holders of record on the relevant record date to
receive interest due on an interest payment date that is on or prior to the
redemption date) plus the make-whole premium applicable to such series of notes
(the "Redemption Price"). In no event will the redemption price ever be less
than 100% of the principal amount of the Notes plus accrued and unpaid interest
to the redemption date.

     The amount of the make-whole premium with respect to any note (or portion
thereof) of any such series to be redeemed will be equal to the excess, if any,
of:

          (1) the sum of the present values, calculated as of the redemption
     date, of:

           - each interest payment that, but for such redemption, would have
             been payable on the note (or portion thereof) of such series being
             redeemed on each Interest Payment Date occurring after the
             redemption date (excluding any accrued and unpaid interest for the
             period prior to the redemption date), and

           - the principal amount that, but for such redemption, would have been
             payable at the final maturity of the note (or portion thereof) of
             such series being redeemed,

     over

          (2) the principal amount of the note (or portion thereof) of such
     series being redeemed.

     The present values of interest and principal payments referred to in clause
(1) above will be determined in accordance with generally accepted principles of
financial analysis. Such present values will be calculated by discounting the
amount of each payment of interest or principal from the date that each such
payment would have been payable, but for the redemption, to the Redemption Date
at a discount rate equal to the U.S. Treasury yield (as defined below) plus (1)
20 basis points in the case of the 6.75% Transocean Sedco Forex notes and the
6.95% Transocean Sedco Forex notes, (2) 25 basis points in the case of the
7.375% Transocean Sedco Forex notes, and (3) 50 basis points in the case of the
9.125% Transocean Sedco Forex notes and the 9.50% Transocean Sedco Forex notes.

     The make-whole premium will be calculated by an independent investment
banking institution of national standing appointed by us. If we fail to appoint
such an institution at least 45 business days prior to the redemption date, or
if the institution appointed is unwilling or unable to make such calculation,
such calculation will be made by an independent investment banking institution
of national standing appointed by the Transocean Sedco Forex trustee (in any
such case, an "Independent Investment Banker").

     For purposes of determining the make-whole premium, "U.S. Treasury yield"
means an annual rate of interest equal to the weekly average yield to maturity
of U.S. Treasury Notes that have a constant maturity that corresponds to the
remaining term to maturity of the notes,

                                        57


calculated to the nearest 1/12th of a year (the "Remaining Term"). The U.S.
Treasury yield will be determined as of the third business day immediately
preceding the applicable redemption date.

     The weekly average yields of U.S. Treasury Notes will be determined by
reference to the most recent statistical release published by the Federal
Reserve Bank of New York and designated "H.15(519) Selected Interest Rates" or
any successor release (the "H.15 Statistical Release"). If the H.15 Statistical
Release sets forth a weekly average yield for U.S. Treasury Notes having a
constant maturity that is the same as the Remaining Term, then the U.S. Treasury
yield will be equal to such weekly average yield. In all other cases, the U.S.
Treasury yield will be calculated by interpolation, on a straight-line basis,
between the weekly average yields on the U.S. Treasury Notes that have a
constant maturity closest to and greater than the Remaining Term and the U.S.
Treasury Notes that have a constant maturity closest to and less than the
Remaining Term (in each case as set forth in the H.15 Statistical Release). Any
weekly average yields so calculated by interpolation will be rounded to the
nearest 1/100th of 1%, with any figure of 1/200 of 1% or above being rounded
upward. If weekly average yields for U.S. Treasury Notes are not available in
the H.15 Statistical Release or otherwise, then the U.S. Treasury yield will be
calculated by interpolation of comparable rates selected by the Independent
Investment Banker.

     If less than all of the notes of any such series are to be redeemed, the
Transocean Sedco Forex trustee will select the notes of such series to be
redeemed by such method as the trustee deems fair and appropriate. The trustee
may select for redemption notes and portions of notes of such series in amounts
of $1,000 or whole multiples of $1,000.

     The notes are not entitled to the benefit of any sinking fund or other
mandatory redemption provisions.

RESTRICTIVE COVENANTS

     In the following discussion, "we" or "our" means Transocean Sedco Forex
Inc. and its subsidiaries, unless the context indicates otherwise. When we refer
to our "drilling rigs and drillships," we mean any drilling rig or drillship (or
the stock or indebtedness of any subsidiary owning a drilling rig or drillship)
that we lease or own all or part of and that our board of directors deems of
material importance to us. No drilling rig or drillship that has a gross book
value that is less than 2% of consolidated net tangible assets will be deemed of
material importance. When we refer to "consolidated net tangible assets," we
mean the total amount of our assets (less reserves and other properly deductible
items) after deducting current liabilities (other than those that are extendable
at our option to a date more than 12 months after the date the amount is
determined), goodwill and other intangible assets shown in our most recent
consolidated balance sheet prepared in accordance with accounting principles
generally accepted in the United States.

  LIMITATION ON LIENS

     In the Transocean Sedco Forex indenture, we have agreed that we will not
create, assume or allow to exist any debt secured by a lien upon any of our
drilling rigs or drillships, unless we secure the Transocean Sedco Forex notes
equally and ratably with the secured debt. This covenant also applies to other
series of debt securities issued under the Transocean Sedco Forex indenture
unless the terms of that series expressly provide otherwise. This covenant has
exceptions that permit:

     - liens already existing on the date the applicable series of Transocean
       Sedco Forex notes is issued,

                                        58


     - liens already existing on a particular drilling rig or drillship at the
       time we acquire that drilling rig or drillship, and liens already
       existing on drilling rigs or drillships of a corporation or other entity
       at the time it becomes our subsidiary,

     - liens securing debt incurred to finance the acquisition, completion of
       construction and commencement of commercial operation, alteration, repair
       or improvement of any drilling rig or drillship, if the debt was incurred
       prior to, at the time of or within 12 months after that event, and liens
       securing debt in excess of the purchase price or cost if recourse on the
       debt is only against the drilling rig or drillship in question,

     - liens securing intercompany debt,

     - liens in favor of a governmental entity to secure either (1) payments
       under any contract or statute or (2) industrial development, pollution
       control or similar indebtedness,

     - liens imposed by law such as mechanics' or workmen's liens,

     - governmental liens under contracts for the sale of products or services,

     - liens under workers compensation laws or similar legislation,

     - liens in connection with legal proceedings or securing taxes or
       assessments,

     - good faith deposits in connection with bids, tenders, contracts or
       leases,

     - deposits made in connection with maintaining self-insurance, to obtain
       the benefits of laws, regulations or arrangements relating to
       unemployment insurance, old age pensions, social security or similar
       matters or to secure surety, appeal or customs bonds, and

     - any extensions, renewals or replacements of the above-described liens if
       both of the following conditions are met:

          (1) the amount of debt secured by the new lien does not exceed the
     amount of debt secured by the existing lien, plus any additional debt used
     to complete a specific project, and

          (2) the new lien is limited to all or a part of the drilling rigs or
     drillships (plus any improvements) secured by the original lien issued
     under the Transocean Sedco Forex indenture.

     In addition, without securing the debt securities issued under the
Transocean Sedco Forex indenture as described above, we may create, assume or
allow to exist secured debt that would otherwise be prohibited, in an aggregate
amount that does not exceed a "basket" equal to 10% of our consolidated net
tangible assets. When determining whether secured debt is permitted by this
exception, we must include in the calculation of the "basket" amount all of our
other secured debt that would otherwise be prohibited and the present value of
lease payments in connection with sale and lease-back transactions that would be
prohibited by the "Limitation on Sale and Lease-Back Transactions" covenant
described below if this exception did not apply.

  LIMITATION ON SALE AND LEASE-BACK TRANSACTIONS

     We have agreed that we will not enter into a sale and lease-back
transaction covering any drilling rig or drillship, unless one of the following
applies:

     - we could incur debt secured by the leased property in an amount at least
       equal to the present value of the lease payments in connection with that
       sale and lease-back transaction without violating the "Limitation on
       Liens" covenant described above, or

     - within six months of the effective date of the sale and lease-back
       transaction, we apply an amount equal to the present value of the lease
       payments in connection with the sale and lease-back transaction to (1)
       the acquisition of any drilling rig or drillship or (2) the

                                        59


       retirement of long-term debt ranking at least equally with the debt
       securities issued under the Transocean Sedco Forex indenture.

     When we use the term "sale and lease-back transaction," we mean any
arrangement by which we sell or transfer to any person any drilling rig or
drillship that we then lease back from them. This term excludes leases shorter
than three years, intercompany leases, leases executed within 12 months of the
acquisition, construction, improvement or commencement of commercial operation
of the drilling rig or drillship, and arrangements pursuant to any provision of
law with an effect similar to the former Section 168(f)(8) of the Internal
Revenue Code of 1954 (which permitted the lessor to recognize depreciation on
the property).

  CONSOLIDATION, MERGER AND SALE OF ASSETS

     The Transocean Sedco Forex indenture generally permits a consolidation or
merger between us and another entity. The Transocean Sedco Forex indenture also
permits our transfer or disposal of all or substantially all of our assets. We
have agreed, however, that we will consolidate with or merge into any entity, or
transfer or dispose of all or substantially all of our assets to any entity,
only if:

     - the resulting entity assumes the due and punctual payment of the debt
       securities issued under the indenture and the performance of our
       covenants under the indenture, and

     - immediately after giving effect to the transaction, no event of default,
       and no event that, after notice or lapse of time, would become an event
       of default, would occur and be continuing.

     If a resulting entity assumes our obligations under the Transocean Sedco
Forex notes and the indenture as described above, we will be relieved of those
obligations, except in the case of our transfer or disposal of assets by lease.

EVENTS OF DEFAULT

     The following are events of default with respect to the Transocean Sedco
Forex notes:

     - our failure to pay interest on or any additional amounts with respect to
       the Transocean Sedco Forex notes for 30 days,

     - our failure to pay principal of, or any premium on, the Transocean Sedco
       Forex notes when due,

     - our failure to perform any of our other covenants in the Transocean Sedco
       Forex indenture (other than a covenant included in the Transocean Sedco
       Forex indenture solely for the benefit of another series of debt
       securities) for 90 days after written notice by the trustee or by the
       holders of at least 25% in principal amount of all outstanding debt
       securities under the Transocean Sedco Forex indenture, and

     - various events involving a bankruptcy, insolvency or reorganization of
       Transocean Sedco Forex.

     The default under the Transocean Sedco Forex indenture with respect to one
series of debt securities issued under the indenture will not necessarily be a
default with respect to another series. The Transocean Sedco Forex trustee may
withhold notice to the holders of the Transocean Sedco Forex notes of any
default or event of default (except for a default in any payment on the
Transocean Sedco Forex notes) if the trustee considers it in the interest of the
holders of the Transocean Sedco Forex notes to do so.

     In the case of an event of default with respect to the Transocean Sedco
Forex notes, the Transocean Sedco Forex trustee or the holders of at least 25%
in principal amount of the series of Transocean Sedco Forex notes affected by
the default (or, in some cases, of all outstanding
                                        60


debt securities under the indenture, voting as one class) may declare the
principal of the Transocean Sedco Forex notes to be due and payable immediately.
If an event of default relating to events of bankruptcy, insolvency or
reorganization occurs, the principal of the Transocean Sedco Forex notes will
become immediately due and payable without any action on the part of the
Transocean Sedco Forex trustee or any holder. The holders of a majority in
principal amount of the outstanding Transocean Sedco Forex notes may be affected
by the default (or, in some cases, of all outstanding debt securities under the
indenture, voting as one class) in some cases rescind this accelerated payment
requirement. Depending on the terms of our other indebtedness, an event of
default under the indenture may give rise to cross defaults on our other
indebtedness.

     In most cases, the Transocean Sedco Forex trustee will be under no
obligation to exercise any of its rights or powers under the indenture at the
request or direction of any of the holders, unless those holders have offered to
the trustee reasonable indemnity. The holders of a majority in principal amount
of any series of Transocean Sedco Forex notes (or, in some cases, of all
outstanding debt securities under the indenture, voting as one class) may direct
the time, method and place of:

     - conducting any proceeding for any remedy available to the trustee, or

     - exercising any trust or power conferred on the trustee with respect to
       that series of Transocean Sedco Forex notes.

     In the case of an event of default, the Transocean Sedco Forex trustee will
be required to use the degree of care and skill of a prudent man in the conduct
of his own affairs.

     A holder of Transocean Sedco Forex notes may not individually pursue any
remedy under the indenture unless all of the following conditions are met:

     - the holder has previously given written notice to the Transocean Sedco
       Forex trustee of an event of default with respect to that series of
       Transocean Sedco Forex notes,

     - the holders of not less than 25% in principal amount of the outstanding
       Transocean Sedco Forex notes of that series have made a written request
       to the trustee to institute proceedings in its own name,

     - the holder has offered the trustee reasonable indemnity,

     - the trustee has failed to act within 60 days after receipt of the notice
       and indemnity, and

     - the holders of a majority in principal amount of the outstanding
       Transocean Sedco Forex notes of that series have given no direction
       inconsistent with the request.

     The foregoing limitations with respect to remedies do not, however, affect
the right of a holder of any debt security to sue for the enforcement of any
overdue payment.

DEFEASANCE

     When we use the term "defeasance," we mean discharge from some or all of
our obligations under the Transocean Sedco Forex indenture. If we deposit with
the Transocean Sedco Forex trustee money or U.S. government securities
sufficient to make payments on the Transocean Sedco Forex notes of a series on
the dates those payments are due and payable, then at our option either of the
following will occur:

     - we will no longer have any obligation to the holders of the Transocean
       Sedco Forex notes of that series to comply with the restrictive covenants
       under the indenture, and the related events of default will no longer
       apply to us ("covenant defeasance"), but our other obligations under the
       indenture and the Transocean Sedco Forex notes of that series, including
       our obligations to make payments on the Transocean Sedco Forex notes of
       that

                                        61


       series, to register the transfer or exchange of the Transocean Sedco
       Forex notes of that series, to replace stolen, lost or mutilated
       Transocean Sedco Forex notes of that series, to maintain paying agencies
       and to hold monies for payment in trust, will continue, or

     - we will be discharged from all of our obligations with respect to the
       Transocean Sedco Forex notes of that series ("legal defeasance and
       discharge") and holders of the Transocean Sedco Forex notes of that
       series will be entitled to claim payments on their debt securities only
       from the trust fund.

     We will be required to deliver to the trustee an opinion of counsel that
the deposit and related defeasance would not cause the holders of the Transocean
Sedco Forex notes to recognize income, gain or loss for U.S. federal income tax
purposes. If we elect legal defeasance and discharge, that opinion of counsel
must be based upon a ruling from the U.S. Internal Revenue Service or a change
in law to that effect.

TAX ADDITIONAL AMOUNTS

     We will pay any amounts due with respect to the Transocean Sedco Forex
notes without deduction or withholding for any and all present and future
withholding taxes, levies, imposts and charges (a "withholding tax") imposed by
or for the account of the Cayman Islands. If the Cayman Islands requires us to
deduct or withhold any of these taxes, levies, imposts or charges, we will
(subject to compliance by the holder of the Transocean Sedco Forex notes with
any relevant administrative requirements) pay these additional amounts in
respect of principal amount, premium (if any), redemption price, and interest
(if any), in accordance with the terms of the Transocean Sedco Forex notes and
the Transocean Sedco Forex indenture, as may be necessary so that the net
amounts paid to the holder or the trustee after such deduction or withholding
will equal the principal amount, premium (if any), redemption price, and
interest (if any), on the Transocean Sedco Forex notes. However, we will not pay
any additional amounts in the following instances:

     - if any withholding would not be payable or due but for the fact that (1)
       the holder of Transocean Sedco Forex notes (or a fiduciary, settlor,
       beneficiary of, member or shareholder of, the holder, if the holder is an
       estate, trust, partnership or corporation), is a domiciliary, national or
       resident of, or engaging in business or maintaining a permanent
       establishment or being physically present in, the Cayman Islands or
       otherwise having some present or former connection with the Cayman
       Islands other than the holding or ownership of Transocean Sedco Forex
       notes or the collection of principal amount, premium (if any), redemption
       price, and interest (if any), in accordance with the terms of the
       Transocean Sedco Forex notes and the Transocean Sedco Forex indenture, or
       the enforcement of the Transocean Sedco Forex notes or (2) where
       presentation is required, the Transocean Sedco Forex notes were presented
       more than 30 days after the date such payment became due or was provided
       for, whichever is later,

     - if any withholding tax is attributable to any estate, inheritance, gift,
       sales, transfer, excise, personal property or similar tax, levy, impost
       or charge,

     - if any withholding tax is attributable to any tax, levy, impost or charge
       which is payable otherwise than by withholding from payment of principal
       amount, premium (if any), redemption price, and interest (if any),

     - if any withholding tax would not have been imposed but for the failure to
       comply upon our request with certification, information, documentation or
       other reporting requirements concerning the nationality, residence,
       identity or connections with the relevant tax authority of the holder or
       beneficial owner of the Transocean Sedco Forex notes, if this compliance
       is required by statute or by regulation as a precondition to relief or
       exemption from such withholding tax, or

                                        62


     - any combination of the instances described in the preceding bullet
       points.

     We also will not pay any additional amounts to any holder who is a
fiduciary or partnership or other than the sole beneficial owner of the
Transocean Sedco Forex note to the extent that a beneficiary or settlor with
respect to such fiduciary, or a member or such partnership or a beneficial owner
thereof, would not have been entitled to the payment of such additional amounts
had such beneficiary, settlor, member or beneficial owner been the holder of the
Transocean Sedco Forex note.

PAYMENT AND PAYING AGENTS

     We will make payments on the Transocean Sedco Forex notes at the office of
the paying agents we designate from time to time. We may make, at our option,
interest payments by check mailed to the person entitled to the payment as it
appears on the security register. We will make interest payments to the person
in whose name the Transocean Sedco Forex notes are registered at the close of
business on the record date for the interest payment, even if that person no
longer owns the Transocean Sedco Forex notes on the interest payment date.

     We have designated the corporate trust office of the Transocean Sedco Forex
indenture trustee as a paying agent for payments on the Transocean Sedco Forex
notes. We may at any time designate additional paying agents, rescind the
designation of any paying agent or approve a change in the office through which
any paying agent acts. We will, however, be required to maintain a paying agent
in each place of payment for the Transocean Sedco Forex notes.

     Any funds we pay to a paying agent for payments on the Transocean Sedco
Forex notes that remain unclaimed for three years after the payments become due
and payable will be repaid to us, subject to applicable escheat laws. After
repayment to us, the holder of that Transocean Sedco Forex note can claim
payment only from us and not from the paying agent.

MODIFICATION AND WAIVER

     We may modify or amend the Transocean Sedco Forex indenture if the holders
of a majority in principal amount of the outstanding debt securities of all
series issued under the Transocean Sedco Forex indenture (acting as one class)
affected by the modification or amendment consent to it. Without the consent of
the holder of each outstanding debt security affected, however, no modification
may:

     - change the stated maturity of the principal of or any installment of
       principal of or interest on any debt security,

     - reduce the principal amount of, the interest rate on, any additional
       amount with respect to or the premium payable upon redemption of any debt
       security,

     - make the debt security payable in a currency other than originally stated
       in the debt security,

     - change the place where the principal of, any additional amounts with
       respect to or any premium or interest on any debt security is payable,

     - impair the right to institute suit for the enforcement of any payment on
       any debt security,

     - reduce the percentage in principal amount of outstanding debt securities
       necessary to modify the indenture, waive compliance with the provisions
       of the Transocean Sedco Forex indenture or waive defaults, or

     - modify any of the above provisions.

                                        63


     We and the Transocean Sedco Forex trustee may agree to modify, amend or
supplement the Transocean Sedco Forex indenture without the consent of any
holders of Transocean Sedco Forex notes in certain circumstances, including:

     - to evidence the assumption of our obligations under the indenture and the
       debt securities issued under the indenture by a successor,

     - to add covenants or events of default or to surrender any of our rights
       under the indenture,

     - to provide security for any series of debt securities issued under the
       indenture,

     - to make any change that does not adversely affect any outstanding
       Transocean Sedco Forex debt securities of a series,

     - to establish the terms of any series of debt securities,

     - to add provisions necessary to permit or facilitate defeasance of any
       series of debt securities if we have received an opinion of counsel that
       those provisions do not materially adversely affect the holders of any
       series of debt securities,

     - to provide for a successor trustee, or

     - to cure any ambiguity, defect or inconsistency.

     The holders of a majority in principal amount of the outstanding Transocean
Sedco Forex notes of any series (or, in some cases, of all outstanding debt
securities under the indenture or of all series affected) may waive past
defaults under the Transocean Sedco Forex indenture and compliance by us with
our covenants under the indenture. Those holders may not, however, waive any
default in any payment on any debt security of that series or compliance with a
provision that cannot be modified or amended without the consent of each holder
affected.

BOOK-ENTRY SYSTEM

     The Transocean Sedco Forex notes will be represented by one or more global
securities. A global security is a special type of indirectly held security.
Each global security will be deposited with, or on behalf of, The Depository
Trust Company ("DTC") and be registered in the name of a nominee of DTC. Except
under the circumstances described below, the Transocean Sedco Forex notes will
not be issued in definitive form in the name of individual holders.

     Upon the issuance of a global security, DTC will credit on its book-entry
registration and transfer system the accounts of persons designated by the
initial purchaser with the respective principal amounts of the Transocean Sedco
Forex notes represented by the global security. Ownership of beneficial
interests in a global security will be limited to DTC participants (that is,
persons that have accounts with DTC or its nominee) or persons that may hold
interests through DTC participants. Ownership of beneficial interests in a
global security will be shown on, and the transfer of that ownership will be
effected only through, records maintained by DTC or its nominee (except with
respect to persons that are themselves DTC participants).

     So long as DTC or its nominee is the registered owner of a global security,
DTC or the nominee will be considered the sole owner or holder of the Transocean
Sedco Forex notes represented by that global security under the indenture.
Except as described below, owners of beneficial interests in a global security
will not be entitled to have Transocean Sedco Forex notes represented by that
global security registered in their names, will not receive or be entitled to
receive physical delivery of Transocean Sedco Forex notes in definitive form and
will not be considered the owners or holders of the Transocean Sedco Forex notes
under the indenture. Principal and interest payments on Transocean Sedco Forex
notes registered in the name of DTC or its nominee will be made to DTC or the
nominee, as the registered owner. Neither our company, the trustee, any paying
agent or the registrar for the Transocean Sedco Forex notes
                                        64


will have any responsibility or liability for any aspect of the records relating
to or payments made on account of beneficial interests in a global security or
for maintaining, supervising or reviewing any records relating to such
beneficial interests. The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Those
limits and laws may impair the ability to transfer beneficial interests in a
global security.

     We expect that DTC or its nominee, upon receipt of any payment of principal
or interest, will credit immediately the participants' accounts with payments in
amounts proportionate to their beneficial interests in the principal amount of
the relevant global security as shown on the records of DTC or its nominee. We
also expect that payments by participants to owners of beneficial interests in a
global security held through those participants will be governed by standing
instructions and customary practices, as is the case with securities held for
the accounts of customers in bearer form or registered in "street name," and
will be the responsibility of those participants.

     If DTC is at any time unwilling or unable to continue as a depositary and a
successor depositary is not appointed by us within 90 days, we will issue the
Transocean Sedco Forex notes in definitive form in exchange for the entire
global security for the Transocean Sedco Forex notes. In addition, we may at any
time choose not to have the Transocean Sedco Forex notes represented by a global
security and will then issue the Transocean Sedco Forex notes in definitive form
in exchange for the entire global security relating to the Transocean Sedco
Forex notes. In any such instance, an owner of a beneficial interest in a global
security will be entitled to physical delivery in definitive form of the
Transocean Sedco Forex notes represented by the global security equal in
principal amount to that beneficial interest and to have the Transocean Sedco
Forex notes registered in its name. Transocean Sedco Forex notes so issued in
definitive form will be issued as registered Transocean Sedco Forex notes in
denominations of $1,000 and integral multiples thereof, unless otherwise
specified by us.

TRANSFER AND EXCHANGE

     We have appointed the Transocean Sedco Forex trustee as security registrar
for the Transocean Sedco Forex notes. We are required to maintain an office or
agency for transfers and exchanges in each place of payment. We may at any time
designate additional transfer agents for the Transocean Sedco Forex notes or
rescind the designation of any transfer agent.

     In the case of any redemption of the Transocean Sedco Forex notes, we will
not be required:

     - to issue, register the transfer of, or exchange the Transocean Sedco
       Forex notes during a period beginning 15 days before the day of mailing
       of the relevant notice of redemption and ending on the close of business
       on the day of mailing of the relevant notice of redemption, or

     - to register the transfer or exchange of a Transocean Sedco Forex note, or
       portion of a note, selected for redemption, except for the unredeemed
       portion of any Transocean Sedco Forex note we are redeeming in part.

MEETINGS

     Meetings of holders of Transocean Sedco Forex notes or of any or all series
of debt securities issued under the Transocean Sedco Forex indenture may be
convened on notice:

     - by the trustee,

     - by us, if we ask the trustee to call a meeting and it fails to do so, or

     - by the holders of 10% in principal amount of the debt securities of that
       series, if they ask the trustee to call a meeting and it fails to do so.

                                        65


     Holders entitled to vote a majority in principal amount of the outstanding
debt securities of any series constitute a quorum at any meeting of holders of
that series. Except for actions requiring the consent of all holders of the
Transocean Sedco Forex notes affected by the action, any action at a meeting
adopted by the holders of a majority in principal amount of the Transocean Sedco
Forex notes of a series (or a lesser percentage required for the action by the
indenture) will be binding on all holders of the Transocean Sedco Forex notes of
that series.

NOTICES

     Notices to holders of the Transocean Sedco Forex notes will be given by
mail to the holder's address as it appears in the security register.

GOVERNING LAW

     New York law governs the Transocean Sedco Forex indenture and the
Transocean Sedco Forex notes.

THE TRUSTEE

     The Bank of New York is the trustee under the Transocean Sedco Forex
indenture. We may borrow money and maintain other banking relationships, in the
ordinary course of business, with the trustee and its affiliates. The Transocean
Sedco Forex indenture, however, contains limitations on the right of the
trustee, if it becomes one of our creditors, to obtain payment of claims or to
realize on certain property received for any such claim, as security or
otherwise. If the trustee acquires any conflicting interest, it must eliminate
that conflict or resign.

                                        66


                 MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

     The following is a discussion of (1) the material U.S. federal income tax
considerations relating to the exchange offers and consent solicitations and to
the ownership and disposition of the Transocean Sedco Forex notes to initial
holders of such securities who are U.S. holders (as described below) and (2) the
material U.S. federal income and estate tax considerations relating to the
exchange offers and consent solicitations and to the ownership and disposition
of the Transocean Sedco Forex notes to initial holders of such securities who
are non-U.S. holders (as described below). This discussion only addresses tax
considerations relevant to holders that hold R&B Falcon notes, and will hold
Transocean Sedco Forex notes, as capital assets.

     This discussion does not address all tax considerations that may be
important to you in light of your particular circumstances (such as the
alternative minimum tax provisions) or under certain special rules. Special
rules may apply, for instance, to banks, tax-exempt organizations, insurance
companies, dealers in securities or currencies, persons who hold R&B Falcon
notes or Transocean Sedco Forex notes as part of a hedge, conversion or
constructive sale transaction, or straddle or other risk reduction transaction,
traders in securities that elect to use a mark-to-market method of accounting
for their securities holdings, persons whose functional currency for tax
purposes is not the U.S. dollar, or persons who have ceased to be United States
citizens or to be taxed as resident aliens. This discussion is limited to
holders of Transocean Sedco Forex notes who acquire such securities in
connection with the exchange offer. This discussion also does not address the
tax consequences arising under the laws of any foreign, state or local
jurisdiction.

     This discussion is based upon the Internal Revenue Code of 1986, as amended
(the "Code"), its legislative history, existing and proposed U.S. Treasury
regulations, and judicial decisions and administrative interpretations
thereunder, as of the date hereof, all of which are subject to change or
different interpretations, possibly with retroactive effect. We cannot assure
you that the Internal Revenue Service (the "IRS") will not challenge one or more
of the tax results described herein, and we have not obtained, nor do we intend
to obtain, a ruling from the IRS with respect to the U.S. federal tax
consequences of the exchange offers and consent solicitations and of the
ownership and disposition of the Transocean Sedco Forex notes.

     PLEASE CONSULT YOUR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES
TO YOU OF THE EXCHANGE OFFERS AND CONSENT SOLICITATIONS AND OF THE OWNERSHIP AND
DISPOSITION OF THE TRANSOCEAN SEDCO FOREX NOTES, INCLUDING THE EFFECT AND
APPLICABILITY OF STATE, LOCAL OR FOREIGN TAX LAWS.

U.S. HOLDERS

     You are a U.S. holder for purposes of this discussion if you are a
beneficial owner of R&B Falcon notes or Transocean Sedco Forex notes that is,
for U.S. federal income tax law purposes:

     - a citizen or resident of the United States,

     - a corporation organized in or under the laws of the United States or of
       any political subdivision thereof,

     - an estate the income of which is subject to U.S. federal income taxation
       regardless of its source, or

     - a trust if a U.S. court can exercise primary supervision over the trust's
       administration and one or more U.S. persons are authorized to control all
       substantial decisions of the trust.

In the case of a holder of R&B Falcon notes or Transocean Sedco Forex notes
which is a partnership, the tax consequences will generally affect the partner
rather than the partnership, but special considerations not here set forth may
apply.

                                        67


  EXCHANGE OFFERS

     The exchange of R&B Falcon notes for Transocean Sedco Forex notes pursuant
to the exchange offers will be a taxable transaction for U.S. federal income tax
purposes. Accordingly, if you tender your R&B Falcon notes, you will generally
recognize gain or loss equal to the difference between the issue price, as
defined below, of the Transocean Sedco Forex notes which you receive and your
adjusted basis in the R&B Falcon notes. This gain or loss will generally be
capital gain or loss except for gain attributable to accrued market discount, if
any. In addition, you will recognize ordinary interest income on the amount of
accrued and unpaid interest on the R&B Falcon notes which you have not
previously included in income.

     If the Transocean Sedco Forex notes are publicly traded, within the meaning
of the applicable Treasury regulations, or the Transocean Sedco Forex notes are
not publicly traded but the R&B Falcon notes are publicly traded, the issue
price of the Transocean Sedco Forex notes will be the fair market value of such
publicly traded notes reduced by the amount of pre-issuance accrued interest on
the Transocean Sedco Forex notes. We believe that the requisite public trading
will exist and intend to take this position for all relevant reporting and other
purposes. Moreover, we intend to reduce the issue price of the Transocean Sedco
Forex notes by the amount of pre-issuance accrued interest on such notes, and
you should also compute the issue price in such manner. See "-- Taxation of
Interest."

  CONSENT PAYMENTS


     The proper treatment of the consent payments is unclear. However, we and
R&B Falcon intend to take the position that the payments will represent ordinary
income to holders in the full amount of the payments, without reduction by any
portion of a holder's basis in the R&B Falcon notes. You should consult your own
tax advisor as to possible alternative treatments of the consent payments.


  TAXATION OF INTEREST

     Generally, you will be required to include interest received on a
Transocean Sedco Forex note as ordinary income at the time it accrues or is
received, in accordance with your regular method of accounting for U.S. federal
income tax purposes. However, Transocean Sedco Forex intends to treat, and you
should also treat, a portion of the interest paid on the first payment date as a
return of pre-issuance accrued interest that is not taxable and is not income.

  DISCOUNT OR PREMIUM


     If the face amount of any Transocean Sedco Forex note exceeds the issue
price of the note (other than by an amount qualifying for a de minimis
exception), the excess will constitute original issue discount. You must include
such original issue discount in income as ordinary income as it accrues on the
basis of a constant yield to maturity, regardless of the receipt of cash
representing such income. Your basis in the Transocean Sedco Forex notes will be
increased by the amount of original issue discount includible in your gross
income as it accrues. The excess will qualify for a de minimis exception if it
is less than 0.25% of the face amount of such note, multiplied by the number of
complete years to maturity. Because we intend to determine the issue price of
such note by reference to the fair market value of either the R&B Falcon notes
or the Transocean Sedco Forex notes on the exchange date, we cannot know before
the exchange date whether any Transocean Sedco Forex note will have original
issue discount. However, recent estimates by Transocean Sedco Forex and R&B
Falcon indicate that, if the fair market value of the Transocean Sedco Forex
notes and R&B Falcon notes were the same on the date of the exchange as on the
date when the estimates were made, there would be no original issue discount
(other than an amount qualifying for a de minimis exception) on any Transocean
Sedco Forex note.


                                        68


     If the issue price of a Transocean Sedco Forex note exceeds its face
amount, you will be considered to have purchased such security with "amortizable
bond premium" equal in amount to such excess. You may elect to amortize such
premium by offsetting against the interest otherwise required to be included in
income in respect of such security during any taxable year the allocable portion
of such premium, determined under the constant yield method over the remaining
term. In such a case, your basis in the security will be reduced by the amount
of bond premium offset against interest.

     The rules concerning discounts and premiums are complex, and you should
consult your tax advisor to determine how, and to what extent, any discount or
premium will be included in your income (in the case of any discount) or
amortized (in the case of any premium), and as to the desirability, mechanics
and consequences of making any elections in connection therewith.

  SALE, EXCHANGE OR RETIREMENT OF THE TRANSOCEAN SEDCO FOREX NOTES


     With certain exceptions, upon the sale, exchange or retirement of a
Transocean Sedco Forex note, you will recognize gain or loss equal to the
difference between the sale or redemption proceeds and your adjusted tax basis
in such security. Your adjusted tax basis in a Transocean Sedco Forex note will
generally equal your cost for such security, increased by any accrued discount
or decreased by any amortized premium during your holding period of the note.
Gain or loss realized on the sale, exchange or retirement of a Transocean Sedco
Forex note (except for certain payments of accrued interest, see below) will
generally be capital gain or loss and will be long-term capital gain or loss if
such security is held for more than one year. You should consult your tax
advisors regarding the treatment of capital gains (which may be taxed at lower
rates than ordinary income for taxpayers who are individuals) and losses (the
deductibility of which is subject to limitations). Payments for accrued interest
not previously included in income will be treated as ordinary interest income.


NON-U.S. HOLDERS

     You generally are a non-U.S. holder for purposes of this discussion if you
are a beneficial owner of R&B Falcon notes or Transocean Sedco Forex notes that
is not a U.S. holder, as described above.

  EXCHANGE OFFERS

     You generally will not be subject to U.S. federal income and withholding
tax on gain realized on the exchange of R&B Falcon notes for Transocean Sedco
Forex notes pursuant to the exchange offers unless:

     - you are an individual present in the United States for 183 days or more
       in the year of such exchange and either (A) you have a "tax home" in the
       United States and certain other requirements are met or (B) the gain from
       the exchange is attributable to an office or other fixed place of
       business maintained by you in the United States, or

     - the gain is effectively connected with your conduct of a U.S. trade or
       business. See "-- Income Effectively Connected with U.S. Trade or
       Business."

However, to the extent that disposition proceeds represent interest on the R&B
Falcon notes accruing between interest payment dates, you will be required to
establish an exemption from United States federal income tax. See "-- Taxation
of Interest" for a discussion of the requirements of the exemption.

  CONSENT PAYMENTS

     In compliance with U.S. federal withholding tax requirements applicable to
payments of certain U.S. source income to foreign persons, R&B Falcon intends to
withhold tax at the rate of
                                        69


30% on consent payments made to non-U.S. holders, unless the holder establishes
an exemption or a reduced rate. An exemption will apply to a consent payment
which represents effectively connected income to the holder (in which case the
non-U.S. holder should provide IRS Form W-8ECI), and an exemption or reduced
rate may apply to a consent payment when the non-U.S. holder is entitled to the
benefits of a tax treaty (in which case the non-U.S. holder should provide IRS
Form W-8BEN).

     The proper treatment of the consent payments is unclear. Notwithstanding
that R&B Falcon will withhold tax on the consent payments in the absence of an
exemption, it is possible that such withholding is not in fact required, in
which case you would be entitled to a refund of the tax withheld. You should
consult your own tax advisor on this matter.

  TAXATION OF INTEREST

     As long as we are not engaged in the conduct of any trade or business in
the United States, the payment of interest on a Transocean Sedco Forex note by
us or any paying agent of ours to you will not be subject to U.S. federal income
and withholding tax. Even if we were engaged in the conduct of a trade or
business in the U.S. and interest was treated as paid by that U.S. trade or
business, payment of interest would be exempt from U.S. federal income and
withholding tax, provided that:

     - you do not actually or constructively own 10% or more of the total
       combined voting power of all classes of our shares,

     - you are not a controlled foreign corporation that is related to us within
       the meaning of the Code, and

     - the U.S. payor does not have actual knowledge or reason to know that you
       are a U.S. person and either (1) the beneficial owner of the Transocean
       Sedco Forex note certifies to the applicable payor or its agent, under
       penalties of perjury, that it is not a U.S. holder and provides its name
       and address on IRS Form W-8BEN (or a suitable substitute form) or (2) a
       securities clearing organization, bank or other financial institution,
       that holds customers' securities in the ordinary course of its trade or
       business (a "financial institution") and holds the Transocean Sedco Forex
       note, certifies under penalties of perjury that a Form W-8BEN (or a
       suitable substitute form) has been received from the beneficial owner by
       it or by a financial institution between it and the beneficial owner and
       furnishes the payor with a copy of the form or the U.S. payor otherwise
       possesses documentation upon which it may rely to treat the payment as
       made to a non-U. S. person in accordance with U.S. Treasury regulations.

     If such interest is effectively connected with a U.S. trade or business of
yours, see "-- Income Effectively Connected with U.S. Trade or Business."


     Payments made to a non-U.S. holder which are attributable to original issue
discount will generally be treated in the same manner as payments of interest,
as just described.


     A portion of the first payment of stated interest made by us on the
Transocean Sedco Forex notes will represent pre-issuance interest in the amount
of interest on the R&B Falcon notes which was accrued and unpaid on the date of
the exchange. This payment will be treated as a payment by us and subject to the
same U.S. federal withholding tax rules and exemptions applicable to interest
payments, as described above.

                                        70


  GAIN ON DISPOSITION OF THE TRANSOCEAN SEDCO FOREX NOTES

     You generally will not be subject to U.S. federal income and withholding
tax on gain realized on the sale, exchange or redemption of a Transocean Sedco
Forex note unless:

     - you are an individual present in the United States for 183 days or more
       in the year of such sale, exchange or redemption and either (A) you have
       a "tax home" in the United States and certain other requirements are met
       or (B) the gain from the disposition is attributable to an office or
       other fixed place of business maintained by you in the United States, or

     - the gain is effectively connected with your conduct of a U.S. trade or
       business. See "-- Income Effectively Connected with U.S. Trade or
       Business."

     However, to the extent that disposition proceeds represent either interest
accruing between interest payment dates or original issue discount accruing
while you held the Transocean Sedco Forex note, you may be required to establish
an exemption from United States federal income and withholding tax. See
"-- Taxation of Interest."

  INCOME EFFECTIVELY CONNECTED WITH U.S. TRADE OR BUSINESS

     Except to the extent otherwise provided under an applicable tax treaty, you
generally will be taxed in the same manner as a U.S. holder with respect to
income or gain on a Transocean Sedco Forex note or R&B Falcon note if such
income or gain is effectively connected with a U.S. trade or business of yours.
Effectively connected income received or gain realized by a corporate non-U.S.
holder may also, under certain circumstances, be subject to an additional
"branch profits tax" at a 30% rate (or, if applicable, a lower treaty rate),
subject to certain adjustments. Such effectively connected income or gain will
not be subject to withholding tax if the holder delivers the appropriate form
(currently IRS Form W-8ECI) to the payor.

  U.S. FEDERAL ESTATE TAX

     A Transocean Sedco Forex note held by an individual who at the time of
death is not a citizen or resident of the United States (as specially defined
for U.S. federal estate tax purposes) will not be subject to U.S. federal estate
tax.

BACKUP WITHHOLDING AND INFORMATION REPORTING

  U.S. HOLDERS

     Consent payments and interest payments made on, or the proceeds of the sale
or other disposition of, the R&B Falcon notes or Transocean Sedco Forex notes
may be subject to information reporting and U.S. federal backup withholding tax
(currently at the rate of 30%) if the recipient of those payments fails to
supply an accurate taxpayer identification number or otherwise fails to comply
with applicable United States information reporting or certification
requirements. Any amount withheld from a payment to a U.S. holder under the
backup withholding rules is allowable as a credit against the holder's federal
income tax, provided that the required information is furnished to the IRS.

  NON-U.S. HOLDERS

     In general, backup withholding and information reporting will not apply to
consent payments and interest payments made on, or the proceeds of the sale or
other disposition of, the R&B Falcon notes or Transocean Sedco Forex notes if
the holder establishes by providing a certificate or, in some cases, by
providing other evidence, that the holder is not a U.S. person. Additional
exemptions are available for certain payments made outside the United States.
Non-U.S. holders of R&B Falcon notes or Transocean Sedco Forex notes should
consult their tax advisers regarding the application of information reporting
and backup withholding in their particular

                                        71


situations, the availability of exemptions, and the procedure for obtaining such
an exemption, if available. Any amount withheld from a payment to a non-U.S.
holder under the backup withholding rules will be allowable as a credit against
the holder's U.S. federal income tax, provided that the required information is
furnished to the IRS.

HOLDERS NOT TENDERING IN AN EXCHANGE OFFER

     Although the matter is not entirely free from doubt, if you do not elect to
exchange your R&B Falcon notes for Transocean Sedco Forex notes pursuant to the
exchange offers, the proposed modifications to the R&B Falcon notes (see "The
Proposed Amendments") should not be treated as a taxable exchange of the R&B
Falcon notes for new R&B Falcon notes.

                        CAYMAN ISLANDS TAX CONSEQUENCES

     According to our Cayman Islands counsel, Walkers, there is currently no
Cayman Islands income or profits tax, withholding tax, capital gains tax,
capital transfer tax, estate duty or inheritance tax payable by a holder in
respect of any income, gain or loss derived from holding notes. We have obtained
an undertaking from the Governor-in-Council of the Cayman Islands under the Tax
Concessions Law (1995 Revision), as amended, that, in the event that any
legislation is enacted in the Cayman Islands imposing tax on profits or income,
or on any capital assets, gain or appreciation, or any tax in the nature of
estate duty or inheritance tax, that tax will not apply to us or to any of our
operations or our shares, notes, debentures or other obligations until June 1,
2019. Therefore, there will be no Cayman Islands tax consequences with respect
to holding notes, except that, if the notes are taken into the Cayman Islands in
original form, they will be subject to stamp duty in the amount of one quarter
of one percent of the face value thereof, subject to a maximum of CI$250.00 per
note.

                             TRANSOCEAN SEDCO FOREX

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION

BACKGROUND

     On January 31, 2001, Transocean Sedco Forex completed a merger transaction
with R&B Falcon Corporation. The merger was accounted for as a purchase with
Transocean Sedco Forex as the acquiror for accounting purposes.

SOURCES OF INFORMATION

     Transocean Sedco Forex is providing the following pro forma financial
information concerning Transocean Sedco Forex to help you in your analysis of
the financial aspects of the exchange offers for properly tendered R&B Falcon
notes. We derived this information from the audited and unaudited financial
statements of Transocean Sedco Forex for the periods presented. The information
is only a summary, and you should read it in conjunction with the financial
information incorporated by reference in this prospectus and consent
solicitation statement. See "Where You Can Find More Information" beginning on
page iii.

HOW WE PREPARED THE UNAUDITED PRO FORMA FINANCIAL INFORMATION

     The pro forma operating results data for the year ended December 31, 2000
and the nine months ended September 30, 2001 for Transocean Sedco Forex assume
that the merger with R&B Falcon and the exchange offers were completed on
January 1, 2000 and that all R&B Falcon notes were tendered by the applicable
consent payment deadline and not withdrawn.

     If Transocean Sedco Forex had merged with R&B Falcon on the date assumed in
the pro forma financial statements, Transocean Sedco Forex might have performed
differently. You should not rely on the pro forma financial information as an
indication of the financial position or results of operations that Transocean
Sedco Forex would have achieved had the merger taken place earlier.

     Transocean Sedco Forex prepared the pro forma combined financial
information for the R&B Falcon merger using the purchase method of accounting,
with Transocean Sedco Forex treated as the acquiror. As a result, the assets and
liabilities of R&B Falcon are recorded at fair value with the excess of the
purchase price over the sum of these fair values recorded as goodwill.


     The balance sheet data for Transocean Sedco Forex reflects the effect of
the merger with R&B Falcon and assumes that the exchange offers were completed
on September 30, 2001 and that all R&B Falcon notes were tendered by the
applicable consent payment deadline and not withdrawn. In connection with the
exchange offer, all payments made to third parties will be expensed in the
period incurred.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 34.1 of the Company's Articles of Association provides that:

     No directors will be personally liable to the Company or, if any, its
members for monetary damages for breach of fiduciary duty as a director, except
for liability (i) for any breach of the director's duty of loyalty to the
Company or, if any, to its members, (ii) for acts or omissions not in good faith
or that involve intentional misconduct or a knowing violation of law or (iii)
for any transaction from which the director derived an improper personal
benefit.

     The Company will indemnify, to the fullest extent permitted by the laws of
the Cayman Islands as from time to time in effect, if any, any person who was or
is a party or is threatened to be made a party to, or otherwise requires
representation by counsel in connection with, any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (whether or not an action by or in the right of the Company) by
reason of the fact that he is or was a director or officer of the Company, or,
while serving as a director or officer of the Company, is or was serving at the
request of the Company, as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, or by reason
of any action alleged to have been taken or omitted in such capacity. The right
to indemnification conferred by Section 34.1 also includes the right of such
persons to be paid in advance by the Company for their expenses to the fullest
extent permitted by the laws of the Cayman Islands as from time to time in
effect.

     Unless otherwise determined by the Company's board of directors, the
Company will indemnify to the fullest extent permitted by the laws of the Cayman
Islands as from time to time in effect, if any, any person who was or is a party
or is threatened to be made a party to, or otherwise requires representation by
counsel in connection with, any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (whether or
not an action by or in the right of the Company), by reason of the fact that he
is or was an employee (other than an officer) or agent of the Company as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, or by reason of any action alleged to have
been taken or omitted in such capacity.

     The rights and authority conferred by Section 34.1 are not exclusive of any
other right that any person has or hereafter acquires under any law, provision
of the Company's Articles of Association or Memorandum of Association,
agreement, vote of members of the Company or of the board of directors of the
Company or otherwise.

     The Company also has directors and officers liability insurance that would
indemnify its directors and officers against damages arising out of certain
kinds of claims that might be made against them based on their negligent acts or
omissions while acting in their capacity as such.

     Agreements that may be entered into with underwriters, dealers and agents
who participate in the distribution of securities of the Company may contain
provisions relating to the indemnification of the Company's officers and
directors.

     See "Item 22. Undertakings" for a description of the SEC's position
regarding the indemnification of directors and officers for liabilities arising
under the Securities Act.

ITEM 22. UNDERTAKINGS.


     (a) The undersigned Registrant hereby undertakes:



          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:



             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act;



             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) under the Securities Act if,
        in the aggregate, the changes in volume and price represent no more than
        a 20 percent change in the maximum aggregate offering price set forth in
        the "Calculation of Registration Fee" table in the effective
        registration statement;



             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;



          PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
     apply if the registration statement is on Form S-3 or Form S-8 and the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed by the registrant
     pursuant to section 13 or section 15(d) of the Securities Exchange Act of
     1934, as amended (the "Exchange Act") that are incorporated by reference in
     the Registration Statement.



          (2) That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered therein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.



          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.



     (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.



     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that, in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless, in the opinion of its counsel, the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the

                                       II-4


question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.


     (d) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.



     (e) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.


                                       II-5


                                   SIGNATURES


     Pursuant to the requirements of the Securities Act of 1933, the Registrant
has duly caused this amendment to the registration statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in the City of Houston,
the State of Texas, on January 30, 2002.
