EXPLANATORY NOTE The registrant hereby amends its Current Report on Form 8-K dated December 31, 1999 (as amended by its Current Report on Form 8-K/A filed with the Securities and Exchange Commission on March 10, 2000) to (i) correct the number of shares of the registrant that were issued in the merger of Transocean Offshore Inc. and Sedco Forex Holdings Limited, as reported in the third paragraph under Item 2, and (ii) make related corrections to the pro forma earnings per share and shares outstanding. ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS On December 31, 1999 at 1:00 a.m. Houston time (the "Effective Time"), Transocean Offshore Inc. ("Transocean") completed its merger with Sedco Forex Holdings Limited ("Sedco Forex"), the former offshore contract drilling service business of Schlumberger Limited ("Schlumberger"), following the spin-off of Sedco Forex to Schlumberger stockholders on December 30, 1999. Under the terms of the Agreement and Plan of Merger dated as of July 12, 1999 among Schlumberger, Sedco Forex, Transocean and Transocean SF Limited, a wholly owned Transocean subsidiary, Transocean SF Limited merged with and into Sedco Forex, and Schlumberger stockholders exchanged all of the Sedco Forex shares distributed by Schlumberger in the Sedco Forex spin-off for ordinary shares of Transocean. At an Extraordinary General Meeting of Shareholders held on December 10, 1999, Transocean shareholders approved, among other things, the issuance of the Transocean ordinary shares required to consummate the merger with Sedco Forex. Effective upon the merger, Transocean changed its name to "Transocean Sedco Forex Inc." At the Effective Time of the merger, Sedco Forex owned, had an ownership interest in or operated 40 mobile offshore drilling rigs. Sedco Forex's fleet consisted of three fourth-generation semisubmersibles, twenty second- and third- generation semisubmersibles, one first-generation semisubmersible, two drillships, ten jackup rigs and four tenders, as well as one multi-purpose service jackup rig, six swamp barges and two land drilling rigs. Sedco Forex also had under construction three Sedco Express-class semisubmersibles and one independent-leg cantilevered jackup rig. Sedco Forex contracted these drilling rigs, related equipment and work crews primarily on a dayrate basis to drill oil and gas wells. Transocean Sedco Forex intends to continue to use Sedco Forex's assets in substantially the same manner in its worldwide offshore contract drilling business. Pursuant to the terms of the merger agreement, Schlumberger stockholders received 0.1936 ordinary shares of Transocean for each share of capital stock of Sedco Forex distributed in the spin-off of Sedco Forex (the "Merger Ratio"). On December 30, 1999, the closing price on the New York Stock Exchange of Transocean ordinary shares was $32 15/16 per share. Transocean issued 109,564,268 ordinary shares to Schlumberger stockholders in the merger, of which 145,102 were sold on the market for cash paid in lieu of fractional shares. The Merger Ratio was determined through arm's-length negotiations. Prior to the merger, (i) Transocean received the written opinion from its independent financial advisors that, as of the date of such opinion, the Merger Ratio was fair to Transocean and its shareholders from a financial point of view, and (ii) Schlumberger received the written opinion of its independent financial advisors that, as of the date of such opinion, the Merger Ratio was fair to Schlumberger's stockholders from a financial point of view, as if they were current holders of the shares of Sedco Forex capital stock. Transocean accounted for the merger using the purchase method, with Sedco Forex treated as the acquiror for accounting purposes. On December 31, 1999 following the Effective Time, Sedco Forex repaid indebtedness to Schlumberger in the aggregate amount of $303.6 million with the proceeds of an intercompany loan from Transocean to Sedco Forex. Transocean borrowed the amount it required to fund this advance under a $400 million term loan facility with a group of financial institutions led by SunTrust Bank, Atlanta. Upon completion of the merger, Jean P. Cahuzac, formerly President of Sedco Forex, was appointed Executive Vice President and President, Europe, Middle East and Africa of Transocean Sedco Forex. David Mullen, formerly Director of Personnel for Geco Prakla, a unit of Schlumberger, was appointed Vice President, Human Resources of Transocean Sedco Forex. Ricardo Rosa, formerly the Controller of Sedco Forex, was appointed Vice President and Controller of Transocean Sedco Forex. In addition, Victor E. Grijalva, who is currently Vice Chairman of Schlumberger, and Arthur Lindenauer, who is currently a Senior Advisor of Schlumberger and President of Schlumberger Technology Corporation, were elected to the Transocean Sedco Forex Board of Directors. Under the merger agreement, Transocean agreed to use its reasonable best efforts to maintain a 50 percent allocation of directorships of Transocean Sedco Forex for Schlumberger designees and to maintain the initial appointments thereunder for a period of three years following the merger. Pursuant to the merger agreement, Mr. Grijalva was 1

appointed Chairman of the Board of Transocean Sedco Forex and entered into a consulting agreement with Transocean Sedco Forex.

SEDCO FOREX HOLDINGS LIMITED NOTES TO CONDENSED COMBINED FINANCIAL STATEMENTS (Unaudited) NOTE 1 - PRINCIPLES OF COMBINATION AND MERGER Principles of Combination The accompanying combined Sedco Forex Holdings Limited financial statements include the offshore contract drilling service business of Schlumberger Limited and its subsidiaries ("Schlumberger"), which is comprised of certain businesses, operations, assets and liabilities of Sedco Forex Holdings Limited, its subsidiaries and Schlumberger, in accordance with a distribution agreement described below (collectively referred to as "Sedco Forex"). Although Sedco Forex was not a separate public company, the accompanying combined financial statements are presented as if Sedco Forex had existed as an entity separate from its parent, Schlumberger. The combined financial statements include the historical assets, liabilities, revenues and expenses that were directly related to the offshore contract drilling service business of Schlumberger during the periods presented and have been prepared using Schlumberger's historical basis in the assets and liabilities and the historical results of operations of Sedco Forex. Certain amounts of Schlumberger's corporate expenses, including centralized research and engineering, legal, accounting, employee benefits, real estate, insurance, information technology services, treasury and other corporate and infrastructure costs, although not directly attributable to Sedco Forex's operations, were allocated to Sedco Forex on bases that Schlumberger and Sedco Forex considered to be a reasonable reflection of the utilization of services provided or the benefit received by Sedco Forex (see Note 3). However, the financial information included herein may not reflect the combined financial position, operating results, changes in equity and cash flows of Sedco Forex in the future or what they would have been had Sedco Forex been a separate, stand- alone entity during the periods presented. All significant intercompany accounts and transactions within Sedco Forex have been eliminated. Because Sedco Forex historically did not operate as a separate, stand-alone entity, and in many cases Sedco Forex's results were included in the consolidated financial statements of Schlumberger on a divisional basis, there are no separate meaningful historical equity accounts for Sedco Forex. Changes in equity represent Schlumberger's contribution of its net investment in Sedco Forex after giving effect to the net earnings of Sedco Forex, dividends paid, plus net cash transfers to and from Schlumberger and other transfers from Schlumberger. Certain assets and liabilities included in these financial statements, primarily associated with employee benefits, income taxes and balances due to or from Schlumberger companies other than Sedco Forex, were retained by Schlumberger in accordance with the distribution agreement described below. In addition, certain financial matters were agreed to which limited debt and required a minimum cash level at the time of the audited pre-closing financial statements delivered prior to the distribution. Sedco Forex provided offshore drilling services with semisubmersibles, jackup rigs, dynamically positioned drillships and drilling tenders to customers throughout the world. Sedco Forex principally operated in one industry segment, offshore contract drilling services. Distribution to Shareholders and Merger with Transocean Offshore Inc. Effective July 12, 1999, Sedco Forex, Schlumberger, Transocean Offshore Inc. ("Transocean") and a wholly-owned subsidiary of Transocean entered into a merger agreement. At the same time, Schlumberger and Sedco Forex entered into a distribution agreement that provided for a series of combination transactions which included: the transfer of certain assets and liabilities between Sedco Forex and Schlumberger and the distribution of Sedco Forex stock to Schlumberger shareholders on December 30, 1999. On December 31, 1999 after the distribution, Sedco Forex merged with a wholly-owned subsidiary of Transocean and Schlumberger shareholders received shares of Transocean in exchange for their shares of Sedco Forex. Following the distribution and merger, Schlumberger shareholders owned approximately 52 percent of the outstanding ordinary shares of the combined company that was renamed Transocean Sedco Forex Inc. These historical combined financial statements are for a prior interim period and do not reflect the merger. 6

SEDCO FOREX HOLDINGS LIMITED NOTES TO CONDENSED COMBINED FINANCIAL STATEMENTS-(Continued) (Unaudited) NOTE 2 - GENERAL BASIS OF PRESENTATION - The accompanying condensed combined financial statements of Sedco Forex have been prepared without audit in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission. Accordingly, pursuant to such rules and regulations, these financial statements do not include all disclosures required by accounting principles generally accepted in the United States for complete financial statements. Operating results for the nine month period ended September 30, 1999 are not necessarily indicative of the results that may be expected for the year ended December 31, 1999 or for any future period. In connection with the preparation of these financial statements, management was required to make estimates and assumptions that affect the reported amount of assets, liabilities, revenues, expenses and disclosure of contingent liabilities. Actual results could differ from such estimates. The accompanying condensed combined financial statements and notes thereto should be read in conjunction with the audited combined financial statements and notes thereto included within Exhibit 20.1 to the registrant's Current Report on Form 8-K filed November 9, 1999. SUPPLEMENTARY CASH FLOW INFORMATION - Cash payments for interest and income taxes, net were $16.9 million and $26.8 million, respectively, for the nine months ended September 30, 1999 and $16.0 million and $21.3 million, respectively, for the nine months ended September 30, 1998. CAPITALIZED INTEREST - Interest costs for the construction and upgrade of qualifying assets are capitalized. Sedco Forex capitalized interest costs on construction work in progress of $20.3 million and $4.5 million for the nine months ended September 30, 1999 and 1998, respectively. INTERIM FINANCIAL INFORMATION - The financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim periods. Such adjustments are considered to be of a normal recurring nature unless otherwise identified. NEW ACCOUNTING PRONOUNCEMENTS - In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 133, Accounting for Derivative Instruments and Hedging Activities. In June 1999, the FASB issued SFAS No. 137, Accounting for Derivative Instruments and Hedging Activities - Deferral of the Effective Date of FASB 133 to delay the required effective date for adoption of SFAS No. 133 to fiscal years beginning after June 15, 2000. Because of Sedco Forex's limited use of derivatives to manage its exposure to fluctuations in foreign exchange rates and interest rates, management does not anticipate that the adoption of the new statement will have a material effect on the results of operations or the financial position of Sedco Forex. Sedco Forex will adopt SFAS No. 133 as of January 1, 2001. NOTE 3 - RELATED PARTY TRANSACTIONS In certain countries, Sedco Forex participated in Schlumberger's centralized treasury and cash processes. In these countries, cash was managed either through zero balance accounts or an interest-bearing offsetting mechanism. Cash disbursements for operations, acquisitions and other investments were funded as needed from Schlumberger. The combined financial statements include allocations of certain corporate expenses, including centralized research and engineering, legal, accounting, employee benefits, real estate, insurance, information technology services, treasury and other corporate and infrastructure costs. These allocations were determined on bases that Schlumberger and Sedco Forex considered to be a reasonable reflection of the utilization of services provided or the benefit received by Sedco Forex. The allocation methods included relative revenues, headcount, square footage, transaction processing costs, adjusted operating expenses and others. These allocations resulted in charges being recorded in Sedco Forex's results of operations as follows: 7

SEDCO FOREX HOLDINGS LIMITED NOTES TO CONDENSED COMBINED FINANCIAL STATEMENTS-(Continued) (Unaudited) Nine Months Ended September 30, 1999 1998 - ---------------------------------- ------- ------- (In thousands) Cost of services $41,158 $54,490 Research and engineering 3,445 2,450 General and administrative 5,534 7,060 ------- ------- $50,137 $64,000 ======= ======= At September 30, 1999 Sedco Forex had long-term debt from related parties of $495.7 million. These loans charged interest at rates based on fifty basis points over the LIBOR. These loans were used to finance both Sedco Forex's existing fleet of rigs and ongoing major construction projects. On December 31, 1999, Sedco Forex repaid this indebtedness to Schlumberger with proceeds from a loan from Transocean. Interest expense on these loans aggregated $20.7 million and $8.7 million for the nine months ended September 30, 1999 and 1998, respectively. The related party receivables and payables balances included in the combined balance sheet represent amounts arising from intercompany transactions entered into by Sedco Forex to settle outstanding customer and trade receivables and payables with other Schlumberger entities. NOTE 4 - PRO FORMA EARNINGS PER SHARE Sedco Forex did not have a separate capital structure prior to the spin-off from Schlumberger and merger with Transocean. Accordingly, historical earnings per share has not been presented (see Note 1). Pro forma earnings per share for each period presented was calculated using the Transocean Sedco Forex shares issued pursuant to the merger agreement and the dilutive effect of Transocean Sedco Forex stock options granted to former Sedco Forex employees at the time of the merger, as applicable. The reconciliation of the numerator and denominator used for the computation of basic and diluted pro forma earnings per share is as follows: Nine Months ended September 30, 1999 1998 - ------------------------------------------------------ -------- --------- (In thousands, except per share data) Net income for basic and diluted earnings per share $ 70,498 $250,464 -------- -------- Pro forma shares for basic earnings per share 109,564 109,564 Effect of dilutive securities: Employee stock options 72 72 -------- -------- Adjusted pro forma shares and assumed conversions for diluted earnings per share 109,636 109,636 ======== ======== Pro forma basic earnings per share $ 0.64 $ 2.29 -------- -------- Pro forma diluted earnings per share $ 0.64 $ 2.28 -------- -------- 8

(b) Pro Forma Financial Information How We Prepared The Unaudited Pro Forma Financial Information The operating results data assume the spin-off and the merger were completed on January 1, 1998, and the balance sheet data assume the spin-off and the merger were completed on September 30, 1999. If Sedco Forex had been spun off and combined with Transocean in the past, 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 spin-off and merger taken place earlier or of the future results that Transocean Sedco Forex will achieve after the merger. The pro forma combined financial information of Transocean Sedco Forex was prepared using the purchase method, with Sedco Forex treated as the acquiror for accounting purposes. The assets and liabilities of Sedco Forex were recorded at historical amounts, without restatement to fair values. The assets and liabilities of Transocean were recorded at their preliminary estimated fair values at the date of merger, with the excess of the purchase price over the sum of such fair values recorded as goodwill. The preliminary estimated fair values are subject to change. Reclassifications were made to Sedco Forex historical amounts to conform to the pro forma presentation. The Transocean Sedco Forex unaudited condensed pro forma combined financial statements reflect a total purchase price of $2.99 billion, which was based on the calculated market capitalization of Transocean, using an average closing price of Transocean ordinary shares over the seven-day period commencing three days before July 12, 1999, the date the merger was announced, plus the estimated fair value of Transocean's stock options at the merger date, which were assumed by Transocean Sedco Forex. Transaction-Related Expenses Transocean incurred fees and expenses totaling approximately $20 million in connection with the merger and related transactions, including amounts relating to change of control provisions under some of Transocean's benefit plans. None of these costs were included in calculating the purchase price. Sedco Forex's fees and expenses were immaterial. After the merger, Transocean Sedco Forex will incur certain additional charges and expenses relating to restructuring and integrating the operations of Sedco Forex and Transocean. Transocean did not adjust the pro forma information for these additional charges and expenses or for estimated general and administrative expense savings and operational efficiencies that may be realized as a result of the merger. 9

A summary of the pro forma distribution agreement adjustments by balance sheet caption is as follows: (a) Cash and cash equivalents -- Represents the estimated cash adjustment to reduce cash to the $35 million required minimum cash balance. (b) Other current assets -- A reconciliation of the pro forma distribution agreement adjustments to other current assets is as follows: Other current assets retained by Schlumberger $ (1,108) Settlement of related party receivables (83,710) -------- $(84,818) ========= (c) Other assets -- Represents deferred tax assets retained by Schlumberger.

(c) Goodwill -- The merger was accounted for as a purchase, with Sedco Forex as the acquiror for accounting purposes. The adjusted pro forma goodwill amount reflects 100% of the excess purchase price over the preliminary estimated fair values of Transocean's assets and liabilities (see Note 2(g)). The goodwill calculation reflects the actual purchase price of $2.99 billion, based on the $2.94 billion calculated market capitalization of Transocean, using an average closing price of Transocean ordinary shares over the seven- day period commencing three days before July 12, 1999, the date the merger was announced, plus the $0.05 billion estimated fair value at the merger date of Transocean stock options. The calculated purchase price is for accounting purposes only and is not indicative of the value of Transocean ordinary shares received by shareholders of Sedco Forex in connection with the merger. The recording of goodwill and the associated amortization period of 40 years are supported by the nature of the offshore drilling industry, long-lived drilling equipment and the long-standing relationships with core customers. (d) Other assets -- Represents the adjustment needed to record Transocean's defined benefit pension asset at estimated fair value. 14

TRANSOCEAN SEDCO FOREX SUPPLEMENTAL FINANCIAL INFORMATION In reviewing the Unaudited Condensed Pro Forma Combined Financial Statements, the additional supplemental financial information discussed below should be considered. Related Party Transactions Sedco Forex paid insurance premiums to third-party insurance companies for some risks where the insurance risk was then assumed by a wholly-owned affiliate of Schlumberger through a reinsurance program. Transocean Sedco Forex did not continue this insurance program following the merger. The historical Sedco Forex financial statements included insurance expense of approximately $17 million for the nine months ended September 30, 1999 and $55 million for the year ended December 31, 1998 for this insurance program. Schlumberger cost allocations for research and engineering and general and administrative expenses, which amounted to $9 million for the nine months ended September 30, 1999 and $13 million for the year ended December 31, 1998, will not be incurred by Transocean Sedco Forex following the merger. However, some of this expense reduction will be offset by the costs incurred by Transocean Sedco Forex to replace these services through contractual arrangements with Schlumberger or other third parties. The cost of these contractual arrangements or the increased Transocean Sedco Forex overhead to replace these services, to the extent they are continued, cannot be reasonably estimated at this time. However, Transocean Sedco Forex expects that some level of cost savings will be achieved. Depreciation Expense Depreciation expense of $97 million for the nine months ended September 30, 1999 and $125 million for the year ended December 31, 1998 was included in the Sedco Forex historical financial statements. As a result of the merger, Transocean Sedco Forex has conformed the estimated lives of the Sedco Forex rigs and associated equipment to those used by Transocean for similar assets. Since the useful lives used by Transocean are generally longer than those used by Sedco Forex, the result will be lower depreciation expense. The change in estimated lives would have reduced historical Sedco Forex depreciation expense by approximately $51 million for the nine months ended September 30, 1999 and approximately $62 million for the year ended December 31, 1998. 17
