2 ITEM 5. OTHER EVENTS. Beginning on or about November 8, 1999, Transocean Offshore Inc. ("Transocean") expects to begin mailing a Joint Proxy Statement/Prospectus dated October 27, 1999 to its shareholders of record as of November 1, 1999. Selected portions of such Proxy Statement/Prospectus are included as Exhibit 20.1 hereto and are incorporated herein by reference. The Joint Proxy Statement/Prospectus relates to an extraordinary general meeting of Transocean to be held on December 10, 1999 to vote on: - The increase of Transocean's authorized ordinary share capital to $3,000,000, consisting of 300,000,000 ordinary shares, par value $0.01 per share. - The issuance of ordinary shares under the terms of the Agreement and Plan of Merger, dated as of July 12, 1999, among Schlumberger Limited ("Schlumberger"), Sedco Forex Holdings Limited ("Sedco Forex"), Transocean and its wholly owned subsidiary Transocean SF Limited. - The change of Transocean's name to "Transocean Sedco Forex Inc." as a special resolution to be implemented only upon the completion of the merger under the Agreement and Plan of Merger. - The amendment of Transocean's Long-Term Incentive Plan to, among other things, increase the number of ordinary shares reserved for issuance under the plan from 6,300,000 to 13,300,000. - The amendment of Transocean's Employee Stock Purchase Plan to, among other things, increase the number of ordinary shares reserved for issuance under the plan from 250,000 to 750,000. - Any other matters that properly come before the extraordinary general meeting and any adjournments or postponements of the extraordinary general meeting. The Agreement and Plan of Merger calls for the parties to complete the following steps as part of the transaction: - Schlumberger will consolidate its offshore contract drilling business, other than some assets and businesses in the Middle East, Indonesia and Lake Maracaibo, Venezuela, under Sedco Forex Holdings Limited, a wholly owned subsidiary of Schlumberger; - Schlumberger will then distribute the shares of Sedco Forex to Schlumberger's shareholders so that each Schlumberger shareholder receives one share of Sedco Forex capital stock for each share of Schlumberger common stock owned; - A wholly owned subsidiary of Transocean will merge into Sedco Forex, with Sedco Forex surviving the merger as a wholly owned subsidiary of Transocean; - In exchange for the distributed Sedco Forex common stock, Transocean will issue to Schlumberger's shareholders a number of Transocean ordinary shares based on an exchange ratio that will result in the ownership by Schlumberger's shareholders of about 52% of the total issued Transocean ordinary shares upon completion of the merger; and - If the required number of Transocean ordinary shares are voted in favor of a name change, Transocean will change its name to "Transocean Sedco Forex Inc." The Joint Proxy Statement/Prospectus also relates to a special general meeting of shareholders of Schlumberger that will be held on December 10, 1999 to vote on the distribution of the capital stock of Sedco Forex Holdings Limited to the holders of Schlumberger common stock. If Transocean's shareholders approve the increase in Transocean's authorized ordinary share capital and the issuance of ordinary shares in the merger, Schlumberger's shareholders adopt and approve the distribution, and the other conditions to the distribution and merger are satisfied or waived, after the distribution, Sedco Forex will merge with a subsidiary of Transocean as described above. 2

3 ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS. SUMMARY FINANCIAL INFORMATION SOURCES OF INFORMATION Transocean is providing the following selected financial information concerning Sedco Forex, Transocean and Transocean Sedco Forex. This information has been derived from the audited and unaudited financial statements of Sedco Forex and Transocean for the periods presented. The information is only a summary, and you should read it in conjunction with the financial information included in Exhibit 20.1 and Transocean's other filings with the Securities and Exchange Commission. See "Index to Financial Statements" on page F-1 of Exhibit 20.1. In this Current Report on Form 8-K and Exhibit 20.1 hereto: - we refer to Transocean Offshore Inc. as "Transocean"; - we refer to Schlumberger Limited as "Schlumberger"; - we use the term "Sedco Forex" when referring to the historical offshore contract drilling business of Schlumberger that is to be spun off and merged, as well as when referring to that business as consolidated under Sedco Forex Holdings Limited from and after the time of the spin-off, and we also use the term "Sedco Forex" to refer to Sedco Forex Holdings Limited, in each case as the context requires; - we refer in some cases to the shareholders of Sedco Forex immediately after the spin/off and before the merger as "Schlumberger's shareholders" since, after the spin-off and prior to the merger, Schlumberger's shareholders will own all of the stock of Sedco Forex; - we refer to the distribution of the capital stock of Sedco Forex to Schlumberger's shareholders as the "distribution" or the "spin-off"; - we refer to Transocean after the merger as "Transocean Sedco Forex"; - we refer to Transocean's wholly owned merger subsidiary, Transocean SF Limited, as "Merger Sub"; and - we refer to the Agreement and Plan of Merger among Schlumberger, Sedco Forex Holdings Limited, Transocean and Merger Sub as the "merger agreement" and the Distribution Agreement between Schlumberger and Sedco Forex, which provides for the separation of Sedco Forex from the rest of Schlumberger's business and the ensuing spin-off of Sedco Forex to Schlumberger's shareholders, as the "distribution agreement." HOW WE PREPARED THE UNAUDITED PRO FORMA FINANCIAL INFORMATION The operating results data assume the spin-off and the merger had been completed on January 1, 1998, and the balance sheet data assume the spin-off and the merger had been completed on June 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. Transocean prepared the pro forma combined financial information of Transocean Sedco Forex using the purchase method of accounting, with Sedco Forex treated as the acquiror. As a result, Sedco Forex and Transocean recorded the assets and liabilities of Sedco Forex at historical amounts, without restatement to fair values. Transocean recorded the assets and liabilities of Transocean 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 3

4 goodwill. The preliminary estimates of 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 $2.98 billion, which was based on the 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 pro forma balance sheet date, which will be assumed by Transocean Sedco Forex. TRANSACTION-RELATED EXPENSES Transocean estimates that it will incur 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 such costs have been included in calculating the purchase price. Sedco Forex's fees and expenses are expected to be 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. 4

5 SEDCO FOREX SELECTED HISTORICAL COMBINED FINANCIAL DATA The selected historical combined financial data of Sedco Forex in the table below were prepared using the combined financial statements of Sedco Forex. The combined financial information below for each of the three years ended December 31, 1998, and the combined balance sheet data as of December 31, 1997 and 1998, was derived from combined financial statements appearing elsewhere in this Form 8-K audited by PricewaterhouseCoopers LLP, independent accountants. The combined statement of income data for the six months ended June 30, 1999 and 1998 and the years ended December 31, 1995 and 1994 and the combined balance sheet data as of June 30, 1999 and December 31, 1996, 1995 and 1994 were derived from unaudited combined financial statements. In the opinion of management, the unaudited interim financial statements for the six months ended June 30, 1999 and 1998 include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the unaudited periods.

9 TRANSOCEAN SEDCO FOREX NOTES TO UNAUDITED CONDENSED PRO FORMA COMBINED FINANCIAL STATEMENTS (AMOUNTS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS OR UNLESS OTHERWISE INDICATED) (1) Represents the pro forma adjustments to the historical Sedco Forex balance sheet accounts to reflect the following transactions between Schlumberger and Sedco Forex to be effected prior to the spin-off as required by the distribution agreement. - Cash is adjusted to the required minimum cash balance of $35 million; - Certain assets and liabilities included in the historical Sedco Forex accounts are retained by Schlumberger; - Related party receivable and payable balances are settled; - Related party debt is adjusted to $435 million, less the capital expenditure shortfall, plus or minus the working capital adjustment; and - The net amount of the pro forma distribution is treated as an adjustment to the net shareholder's equity of Sedco Forex. 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: Deferred tax assets retained by Schlumberger............. $ (2,200) Settlement of related party receivables.................. (38,214) -------- Total pro forma adjustment to other current assets....................................... $(40,414) ======== (c) Other assets -- Represents deferred tax assets retained by Schlumberger. (d) Current liabilities -- A reconciliation of the pro forma distribution agreement adjustments to current liabilities is as follows: Employee benefit and other liabilities retained by Schlumberger............................................. $(23,834) Current tax liabilities retained by Schlumberger......... (14,780) Settlement of bank overdrafts............................ (6,483) Settlement of related party payables..................... (27,763) -------- Total pro forma adjustment to current liabilities.................................. $(72,860) ======== (e) Long-term debt -- A reconciliation of the pro forma distribution agreement adjustments to long-term debt is as follows: Reduction in related party debt due to capital expenditure shortfall................................... $(309,817) Increase in related party debt due to working capital adjustment............................................ 12,200 Adjustment of related party debt as required by the distribution agreement................................ (163,283) --------- Total pro forma adjustment to long-term debt........................................ $(460,900) ========= The capital expenditure shortfall is calculated as the amount by which actual capital expenditures are less than the forecasted expenditures for 1999, and results in an equivalent reduction in the amount of debt that is permitted at the date of the spin-off of Sedco Forex from Schlumberger. The capital 9

10 expenditure shortfall included above is calculated using expenditures through the pro forma balance sheet date of June 30, 1999. Permitted debt will be increased by the amount of capital expenditures after June 30, 1999 and prior to the distribution date. (f) Deferred taxes and other credits -- A reconciliation of the pro forma distribution agreement adjustments to deferred taxes and other credits is as follows: Postretirement benefit liability retained by Schlumberger... $(5,428) Other employee-related liabilities retained by Schlumberger.............................................. (3,482) ------- Total pro forma adjustment to deferred taxes and other credits................................... $(8,910) ======= (g) Shareholder's equity -- A reconciliation of the pro forma distribution agreement adjustments to shareholder's equity is as follows: Net liabilities to be retained by Schlumberger.............. $ 44,225 Cash adjustment for required minimum cash balance, net of bank overdrafts...........................................

(12,200) Settlement of related party balances........................ 152,832 -------- Total pro forma adjustment to shareholder's equity.......................................... $451,289 ======== (2) A summary of the pro forma adjustments to effect the merger is as follows: (a) Other current assets -- A reconciliation of the pro forma adjustments to other current assets is as follows: Fair value adjustment of prepaid periodic survey and drydock costs....................................................... $10,826 Adjustment of deferred tax assets for the net effect of pro forma adjustments......................................... (4,881) ------- Total pro forma adjustment to other current assets.......................................... $ 5,945 ======= (b) Property and equipment, net -- Represents the adjustment needed to record Transocean's property and equipment at estimated fair value at the date of the merger. (c) Goodwill -- The merger will be accounted for under the purchase method of accounting, with Sedco Forex treated as the acquiror. 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 (2g)). The goodwill calculation assumes a purchase price of $2.98 billion, based on the 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 at the pro forma balance sheet date of Transocean's stock options, which will be assumed by Transocean Sedco Forex. The calculated purchase price is for accounting purposes only and is not indicative of the price at which Transocean ordinary shares will trade immediately before the consummation of the merger or the value of Transocean ordinary shares to be 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 at the date of the merger. 10

11 (e) Current liabilities -- A reconciliation of the pro forma adjustment to current liabilities is as follows: Fair value adjustment of Transocean interest rate swap agreements, net.......................................... $ 4,474 Fair value adjustment of accrued periodic survey and drydock costs..........................................

(g) Shareholders' equity -- Represents the difference between the purchase price (see Note 2(c)) and the book value of the net assets of Transocean at the pro forma balance sheet date, less $2.4 million of estimated costs to issue shares. The purchase price will be allocated based upon the estimated fair values of Transocean assets and liabilities. For purposes of the Unaudited Condensed Pro Forma Combined Financial Statements, the purchase price has been allocated as follows: Historical net book value of Transocean................. $2,113,945 Fair value adjustment of property and equipment, net.... 487,000 Effect of change of control provisions in Transocean's bonus plan............................................ (2,500) Fair value adjustment of Transocean interest rate swap agreements, net.......................................

(153,771) Goodwill................................................ 507,252 ---------- Total purchase price.......................... $2,979,655 ========== (h) Depreciation and amortization -- A reconciliation of the pro forma adjustment to depreciation and amortization is as follows: PRO FORMA SIX MONTHS PRO FORMA ENDED YEAR ENDED JUNE 30, 1999 DECEMBER 31, 1998 ------------- ----------------- Additional depreciation resulting from the adjustment to fair value of Transocean's property and equipment....... $10,107 $27,493 Amortization of goodwill resulting from the merger over a 40-year estimated life. See Note (2c)............... 5,712 11,424 ------- ------- Total pro forma adjustment to depreciation and amortization................................ $15,819 $38,917 ======= ======= (i) Other income (expense) net -- Represents the elimination of interest expense associated with related party debt offset by interest expense on the remaining debt owed to Schlumberger at an assumed 11

12 rate of 5.6875% and a reduction of interest income associated with the reduction in cash balances. The remaining debt balance owed to Schlumberger will be refinanced immediately following the merger. (j) Income taxes -- Represents the incremental benefit from U.S. and foreign income taxes related to pro forma adjustments. The amortization of goodwill and the incremental interest income and expense adjustments are assumed to be nondeductible for tax purposes. (3) Basic earnings per share -- The adjustment to pro forma basic weighted average shares outstanding represents the total estimated Transocean shares expected to be issued to Schlumberger's shareholders in the merger. (4) Diluted earnings per share -- The adjustment to pro forma diluted weighted average shares outstanding is the sum of the basic weighted average shares outstanding plus the estimated dilutive effect of Schlumberger stock options held by Sedco Forex employees. 12

13 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 pays insurance premiums to third-party insurance companies for some risks where the insurance risk is then assumed by a wholly owned affiliate of Schlumberger through a reinsurance program. Transocean Sedco Forex does not currently expect that it would continue this insurance program following the merger. The historical Sedco Forex financial statements include insurance expense of approximately $18 million for the six months ended June 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 $5 million for the six months ended June 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 $64 million for the six months ended June 30, 1999 and $125 million for the year ended December 31, 1998 is included in the Sedco Forex historical financial statements. As a result of the merger, Transocean Sedco Forex will conform 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 to reduce depreciation expense. The change in estimated lives would have reduced historical Sedco Forex depreciation expense by approximately $30 million for the six months ended June 30, 1999 and approximately $62 million for the year ended December 31, 1998. Stock Option Expense Some of the options to purchase Transocean Sedco Forex ordinary shares to be granted to Sedco Forex employees in accordance with the employee matters agreement (to be entered into in connection with the merger agreement) upon completion of the merger are likely to be granted with exercise prices below fair market value. The differences between these exercise prices and fair market value will be recorded as an expense. Based on Schlumberger's September 30, 1999 closing price of $62 5/16 and Transocean's September 30, 1999 closing price of $30 5/8, the amount of this charge would have been about $3 million. The final amount of this charge cannot be determined until the day immediately preceding the distribution date.

1 EXHIBIT 20.1 SELECTED PORTIONS OF JOINT PROXY STATEMENT/PROSPECTUS DATED OCTOBER 27, 1999 Set Forth below are selected portions of the Joint Proxy Statement/Prospectus dated October 27, 1999 of Transocean Offshore Inc. and Schlumberger Limited, which constitutes a part of the Registration Statement on Form S-4 (Registration No. 333-89727) of Transocean Offshore Inc. * * * THE COMPANIES TRANSOCEAN OFFSHORE INC. 4 Greenway Plaza Houston, Texas 77046 Phone: (713) 232-7500 Transocean is a leading international provider of offshore contract drilling services for oil and gas exploration, development and production. As of September 30, 1999, Transocean owned, had partial ownership in or operated 30 mobile offshore drilling units, including the technologically advanced, ultra- deepwater drillships Discoverer Enterprise and Discoverer Spirit, and had one additional Discoverer Enterprise-class drillship under construction. Transocean contracts these drilling rigs, related equipment and work crews primarily on a dayrate basis to drill oil and gas wells. Transocean also provides additional drilling services, including well intervention and management of third-party well service activities. For further information on Transocean, see "Business of Transocean" .... Recent Developments Transocean recently reported its unaudited financial results for each of the quarter and three quarters ended September 30, 1999. Net income for the three months ended September 30, 1999 was $46.9 million or $0.46 per diluted share on revenues of $204.3 million. Comparative net income and diluted earnings per share for the corresponding three months in 1998 were $84.4 million and $0.84, respectively, excluding a nonrecurring after tax gain of $8.5 million, or $0.08 per diluted share, relating to the sale of certain noncore assets and surplus drilling components. Revenues in the prior year period were $269.0 million. For the nine months ended September 30, 1999, net income totaled $188.5 million or $1.87 per diluted share on revenues of $746.2 million. Comparative net income and diluted earnings per share for the nine months ended September 30, 1998 were $217.7 million and $2.16, respectively, exclusive of nonrecurring, after tax gains totaling $22.4 million or $0.22 per diluted share relating to the sale of noncore assets and surplus drilling components and the settlement of a contract dispute. Revenues during the initial nine months of 1998 were $778.9 million. The table below sets forth some of the financial results discussed above.

Proceeds made available under the facility will be used to refinance all intercompany indebtedness of Sedco Forex to Schlumberger upon completion of the merger and for general corporate purposes. Amounts outstanding under the facility will bear interest at floating rates equal to LIBOR plus a margin equal to a percentage based on Transocean's credit rating in effect from time to time or the bank's prime rate, at Transocean's option, and may be prepaid at any time without premium or penalty. No principal amortization is required for the first two years of the facility. The facility will be established under a credit agreement that will contain financial covenants obligating Transocean to maintain a minimum interest coverage ratio and a maximum ratio of consolidated indebtedness to total capitalization and will contain other customary covenants, representations and warranties and conditions precedent. * * * 1

4 RISK FACTORS In addition to the other information contained in this document and the documents incorporated by reference, you should carefully consider the following risk factors before you decide how to vote on the proposed transactions. THE VALUE OF THE TRANSOCEAN ORDINARY SHARES TO BE RECEIVED IN THE MERGER WILL FLUCTUATE. The merger agreement does not contain any provisions for adjustment of the merger exchange ratio and does not provide for rights of termination by either party based upon fluctuations in the per share price of the Transocean ordinary shares prior to the completion of the merger. Because no adjustment will be made to the exchange ratio, the value of the consideration to be received by Schlumberger's shareholders in connection with the spin-off and the merger cannot presently be determined and will vary based upon the market price of Transocean ordinary shares at the time the merger is completed. Such variations may be the result of: - changes in the business or results of operations of Transocean or Sedco Forex; - the prospects for the post-merger operations of Transocean Sedco Forex; - the timing of the merger; - the worldwide supply/demand balance for oil and gas and the prevailing commodity price environment; - competition in the offshore contract drilling industry; - construction risks associated with Transocean's and Sedco Forex's respective newbuild programs; - regulatory considerations; - general market and economic conditions; and - other factors beyond the control of Transocean, Schlumberger or Sedco Forex. Schlumberger's shareholders are urged to obtain current market quotations for their shares and for Transocean ordinary shares. THE PRICE OF TRANSOCEAN SEDCO FOREX ORDINARY SHARES MAY DECLINE AS A RESULT OF THE TRANSACTION. Assuming the transactions are approved by Transocean's and Schlumberger's shareholders and the merger is completed, the number of issued and freely tradeable Transocean ordinary shares will more than double. As a result of the issuance of this large number of additional shares, the market price of Transocean Sedco Forex ordinary shares may experience temporary volatility or decline unrelated to the financial performance of Transocean Sedco Forex. TRANSOCEAN SEDCO FOREX MAY FACE DIFFICULTIES IN INTEGRATING THE OPERATIONS OF SEDCO FOREX AND TRANSOCEAN. Sedco Forex and Transocean have previously operated separately. The proposed management team of Transocean Sedco Forex does not have experience with the combined business. Transocean Sedco Forex may not be able to integrate the operations of Sedco Forex and Transocean without a loss of key officers, employees, customers or suppliers, a loss of revenues, an increase in operating or other costs or other difficulties. In addition, Transocean Sedco Forex may not be able to realize any operating efficiencies and other benefits expected from the merger. Finally, the integration of Transocean and Sedco Forex may be made more difficult or may be otherwise adversely affected by year 2000 problems. Any unexpected costs or delays incurred in connection with such integration could have an adverse effect on Transocean Sedco Forex's business, results of operations or financial condition. THE BUSINESS SEPARATION OF SEDCO FOREX FROM SCHLUMBERGER MAY IMPAIR ASSETS. The separation of Sedco Forex from the rest of Schlumberger's businesses, assets and liabilities requires the transfer of assets, including capital stock and interests in partnerships, limited liability companies and 4

5 similar entities, and liabilities between Sedco Forex and its subsidiaries, on the one hand, and Schlumberger and its other subsidiaries, on the other. In addition, as a part of the business separation, assets and liabilities may be transferred among Sedco Forex subsidiaries, or between those subsidiaries and Sedco Forex itself. Some of these transfers may trigger Sedco Forex liabilities that will not become payable by Sedco Forex until after the merger is completed. Generally, Sedco Forex will not have any recourse against Schlumberger for these liabilities except in the case of (1) certain tax liabilities, customs duties and similar governmental charges for which a claim for indemnification is asserted within specified time periods following the transfer in question and (2) liabilities directly arising out of or directly resulting from the transactions necessary to separate the Sedco Forex business, assets and liabilities from the rest of Schlumberger's business, assets and liabilities, except to the extent those liabilities would have directly arisen out of or directly resulted from the merger. TRANSOCEAN IS SUBJECT TO ANTI-TAKEOVER PROVISIONS. Transocean's articles of association contain, and, accordingly, Transocean Sedco Forex's articles of association will contain, provisions that could prevent or delay an acquisition of Transocean Sedco Forex by means of a tender offer, a proxy contest or otherwise. Such provisions also may adversely affect prevailing market prices for Transocean Sedco Forex's ordinary shares. These provisions, among other things: - classify the Transocean Sedco Forex board into three classes of directors, each of which will serve for staggered three-year periods; - provide that the Transocean Sedco Forex board may designate the terms of any new series of preference shares; - provide that any shareholder of Transocean Sedco Forex who wishes to propose any business or to nominate a person or persons for the election as director at any annual meeting may only do so if advance notice is given to the Secretary of Transocean Sedco Forex; - provide that the exact number of directors on the board can be set between two and twelve from time to time by a majority of the whole board of directors and not by the shareholders; - provide that directors can be removed from office only for cause, as defined in the articles of association, by the affirmative vote of the holders of the issued shares generally entitled to vote; - provide that any vacancy on the board of directors will be filled by the affirmative vote of the remaining directors and not by the shareholders; - provide that any action required or permitted to be taken by the holders of ordinary shares must be taken at a duly called annual or extraordinary general meeting of shareholders unless taken by written consent of all holders of ordinary shares; - provide that only a majority of the directors may call extraordinary general meetings of the shareholders; - limit the ability of the shareholders of Transocean Sedco Forex to amend or repeal certain provisions of Transocean Sedco Forex's articles of association; and - limit transactions between Transocean Sedco Forex and an "interested shareholder," which is generally defined as a shareholder that, together with its affiliates and associates, beneficially, directly or indirectly, owns 15% or more of Transocean Sedco Forex's issued voting shares. See "Description of Capital Stock of Transocean." 5

6 * * * THE TRANSACTIONS THE BUSINESS SEPARATION As further described in the distribution agreement, Schlumberger will consolidate its offshore contract drilling business under its wholly owned subsidiary, Sedco Forex Holdings Limited. To implement this consolidation, before the spin-off: - Schlumberger will transfer to Sedco Forex or its subsidiaries the capital stock or other equity interests of several direct or indirect subsidiaries of Schlumberger that conduct portions of Schlumberger's offshore contract drilling business. - Schlumberger will transfer to Sedco Forex or its subsidiaries those assets relating to Schlumberger's offshore contract drilling business that were previously held by Schlumberger or its subsidiaries other than Sedco Forex or its subsidiaries, including various drilling rigs, spares and equipment; shore-based facilities; leases and personal property used in the business; general intangibles relating to the transferred assets such as drilling contracts; and patents, designs, drawings and other intellectual property identified with such rigs and the offshore contract drilling business. - Sedco Forex will transfer to Schlumberger or its subsidiaries all of the capital stock or other equity interests of those subsidiaries of Sedco Forex that do not conduct Schlumberger's offshore contract drilling business. - Schlumberger and Sedco Forex will use their best efforts to separate various contractual arrangements to provide that those arrangements relating to Sedco Forex do not remain obligations of Schlumberger and that those arrangements not relating to Sedco Forex do not remain obligations of Sedco Forex. - Schlumberger and Sedco Forex will enter into a definitive employee matters agreement with respect to personnel and employee benefit matters, providing for (1) the transfer from Schlumberger to Sedco Forex of all persons who are active Sedco Forex employees as of the spin-off date, other than those whom Schlumberger and Transocean agree will remain with Schlumberger, (2) the allocation of employee-related obligations and liabilities, (3) the treatment of Schlumberger stock options held by Sedco Forex employees at the spin-off date and (4) other transitional and administrative employee matters. - Schlumberger and Sedco Forex will enter into a tax separation agreement to allocate responsibility for the payment of taxes and entitlement to tax refunds, to allocate responsibility and provide for cooperation in the filing of tax returns and related matters, and to provide for certain other matters relating to taxes not provided for in the distribution agreement. - Schlumberger and Sedco Forex will enter into a transition services agreement to provide certain general administrative and logistical support during the transitional period following the merger, which is expected to cover about two years. - Schlumberger and Sedco Forex will enter into agreements regarding the use of shared facilities, such as maintenance yards, inventory warehouse facilities, office space and data processing systems and for the provision of transitional services by Sedco Forex to Schlumberger, such as marine support and marine engineering services. In addition, after Schlumberger has transferred substantially all of the assets of the Sedco Forex business into Sedco Forex or its subsidiaries, Schlumberger will ensure that the outstanding indebtedness of Sedco Forex, including intercompany indebtedness, will be $435 million, subject to adjustment based on agreed levels of working capital and capital expenditures, among other matters, as described in the distribution agreement. 6

7 THE SPIN-OFF On a day preceding the merger, all then-outstanding shares of Sedco Forex capital stock will be distributed by Schlumberger to its shareholders on a pro rata basis such that each Schlumberger shareholder will receive one share of Sedco Forex capital stock for each share of Schlumberger common stock held. THE MERGER Following the spin-off, Merger Sub, a wholly owned subsidiary of Transocean, will merge with and into Sedco Forex, which will survive the merger as a wholly owned subsidiary of Transocean. In the merger, Schlumberger's shareholders will receive Transocean ordinary shares in exchange for their shares of Sedco Forex received in the spin-off. The number of Transocean ordinary shares each Schlumberger shareholder receives will be determined according to the formula in the merger agreement, which will result in the ownership by Schlumberger's shareholders of about 52% of the issued Transocean ordinary shares upon completion of the merger. Instead of fractional shares, the exchange agent will pay these shareholders cash equal to their proportionate interest in the net proceeds from the sale on the NYSE of the aggregate of all fractional Transocean ordinary shares that would otherwise have been issued to them in the merger. * * * 7

8 ACCOUNTING TREATMENT AND CONSIDERATIONS Transocean Sedco Forex will account for the merger using the purchase method of accounting, with Sedco Forex treated as the acquiror. As a result, the assets and liabilities of Sedco Forex will be recorded at historical amounts, without restatement to fair values. The assets and liabilities of Transocean will be recorded at their estimated fair values at the date of the merger, with the excess of the purchase price over the sum of such fair values recorded as goodwill. The purchase price is based upon the market capitalization of Transocean, using an average trading price of Transocean ordinary shares for a reasonable period of time immediately before and after the merger was announced, plus the estimated fair value of Transocean stock options assumed by Transocean Sedco Forex. The purchase price is estimated to be $2.98 billion, which was calculated using a $29.2411 per share valuation of Transocean ordinary shares. The calculated purchase price is for accounting purposes only and is not indicative of the price at which shares of Transocean ordinary shares will trade immediately before the completion of the merger or the value of the Transocean ordinary shares to be received by shareholders of Schlumberger in connection with the merger. * * * 8

9 REGULATORY MATTERS Transocean and Schlumberger must make certain filings and receive certain authorizations from various governmental agencies, both in the United States and internationally, to complete the merger. These filings, notifications and authorizations relate primarily to antitrust and securities law issues. Transocean and Schlumberger intend to pursue vigorously all required regulatory approvals. However, neither Transocean nor Schlumberger can assure that it will obtain all such approvals by the time of its shareholder meeting or at all. In addition, neither Transocean nor Schlumberger can assure that governmental authorities will not impose unfavorable conditions for granting the required approvals. 9

10 U.S. ANTITRUST LAWS Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, and the rules and regulations promulgated thereunder, the parties cannot complete the merger until they have notified and furnished certain information to the Federal Trade Commission and the Antitrust Division of the United States Department of Justice and a specified waiting period expires or is terminated. The parties received notice of early termination of the required waiting period under the U.S. Hart-Scott-Rodino Act on August 16, 1999. OTHER ANTITRUST LAWS Each other country and U.S. state in which Transocean or Schlumberger has operations also may review the merger under its antitrust laws. The parties received clearance from the U.K. competition/antitrust authorities on October 14, 1999. A competition/antitrust filing will also be made in Brazil. At any time before the completion of the merger, any of the relevant governmental authorities or a private person or entity could seek under antitrust laws, among other things, to enjoin the spin-off or the merger or to cause Transocean or Sedco Forex to divest assets or businesses as a condition to completing the merger. Neither Transocean nor Schlumberger can assure that a challenge to the spin-off or the merger will not be made or, if such a challenge is made, that Transocean, Schlumberger or Sedco Forex will prevail. Furthermore, any of the relevant governmental authorities or a private person or entity could seek, under antitrust laws, to take action against Schlumberger or Transocean after the completion of the merger. Transocean and Schlumberger are unable to predict whether such action will be taken or what the outcome of such action may be. The parties' obligation to complete the merger is subject to the condition that no decree, order or injunction of a court of competent jurisdiction prohibits such completion. The parties agreed to use their commercially reasonable best efforts to have any such decree, order or injunction lifted or vacated. The parties also conditioned the completion of the merger on the requirement that no statute, rule or regulation of a governmental authority prohibits the merger or would make it unlawful. COOPERATION OF THE PARTIES Under the merger agreement, the parties agreed to use their best efforts to cooperate in determining which filings need to be made and which consents, approvals, permits or authorizations will need to be obtained prior to the completion of the merger. The parties also agreed to use their best efforts to make or obtain all material filings, consents, approvals, permits or authorizations in a timely manner and to furnish each other with necessary information and reasonable assistance in so doing. Under the merger agreement, the parties must use their best efforts to take any and all steps necessary to gain any consents, approvals, permits or authorizations material to completing the merger or to eliminate any impediments that would restrain, prevent or delay that completion. However, the merger agreement provides that neither party is required to dispose of any material amount of assets to obtain any consents, approvals, permits or authorizations or to remove any impediments to the merger. * * * 10

11 THE TRANSACTION AGREEMENTS This section describes the material provisions of the distribution agreement and the merger agreement. The distribution agreement includes the terms and conditions according to which Sedco Forex will be separated from Schlumberger and spun off to Schlumberger's shareholders. The merger agreement includes the terms and conditions according to which a wholly owned subsidiary of Transocean will merge with and into Sedco Forex, with Sedco Forex surviving the merger as a wholly owned subsidiary of Transocean. The merger agreement is attached to this joint proxy statement/prospectus as Annex A, and the distribution agreement is attached as Annex B. The merger agreement and the distribution agreement are incorporated into this joint proxy statement/prospectus by this reference. This section does not describe all of the provisions of the merger agreement or the distribution agreement, so we urge you to read those agreements carefully in their entirety. THE DISTRIBUTION AGREEMENT SEPARATION OF OFFSHORE CONTRACT DRILLING BUSINESS FROM SCHLUMBERGER Before Sedco Forex is spun off to Schlumberger's shareholders, it must be restructured to separate its business, assets and liabilities from Schlumberger's other business, assets and liabilities. After that separation, Sedco Forex will own, directly or through subsidiaries, Schlumberger's offshore contract drilling assets and businesses, other than four jackups and seven multi-purpose service vessels and related assets in the Middle East, Indonesia and Lake Maracaibo, Venezuela. At that time, Schlumberger and its remaining subsidiaries will own substantially all of the Sedco Forex assets that are not related to the offshore contract drilling business. The Sedco Forex assets and the Schlumberger assets will, to the extent reasonably practicable, be separated. Where complete separation is not reasonably practicable, Sedco Forex and Schlumberger will, subject to Transocean's consent, enter into appropriate arrangements regarding the use of shared assets. Additionally, Sedco Forex and Schlumberger will use their best efforts to amend certain contracts to separate the contractual rights and duties of Sedco Forex from those of Schlumberger. If an amendment cannot be obtained, or if an amendment would be ineffective or would adversely affect the rights of Sedco Forex or Schlumberger under the affected contract, Sedco Forex and Schlumberger will cooperate in negotiating a mutually agreeable arrangement to transfer the economic benefit of the contract to the intended party to the extent possible. Prior to or in conjunction with the completion of the business separation, Sedco Forex and Schlumberger will negotiate and execute a reciprocal transition services agreement anticipated to remain in force for up to two years from the time that the business separation is complete. Sedco Forex and Schlumberger will also conclude independent service agreements whereby Sedco Forex will support certain Schlumberger operations, in some cases for at least three years from the completion of the merger. Each of these transition services agreements will be subject to Transocean's consent. INTERCOMPANY INDEBTEDNESS AND OTHER FINANCING MATTERS After the end of the month in which Schlumberger notifies Transocean that it has transferred substantially all of the offshore contract drilling assets to be transferred to Sedco Forex under the distribution agreement, Schlumberger is to deliver to Transocean an audited balance sheet as of the end of that month. As of the date of that pre-closing balance sheet, Sedco Forex will have $435 million in indebtedness, some of which may be intercompany indebtedness. The $435 million of indebtedness is subject to adjustment for changes in working capital, capital expenditures and other accounts described in the distribution agreement between the date of the agreement and the date of the pre-closing balance sheet. Sedco Forex and Schlumberger will, and will cause their respective subsidiaries to, pay all other intercompany borrowings and payables before the date of that balance sheet. Sedco Forex is required to pay off any intercompany indebtedness included in the $435 million of retained indebtedness no later than the close of business on the day after the distribution of the capital stock of Sedco Forex to Schlumberger's shareholders. On the date of the pre-closing balance sheet, Sedco Forex and its subsidiaries, collectively, are required to have a minimum 11

12 of $35 million on hand in cash. See "Summary -- The Companies -- Transocean Offshore Inc. -- Recent Developments." OPERATIONS OF SEDCO FOREX AFTER THE PRE-CLOSING BALANCE SHEET DATE Except as otherwise provided for in the merger agreement, the distribution agreement or other agreements executed as part of the transaction, after the date of the pre-closing balance sheet, Sedco Forex will be prohibited from doing any of the following: - paying dividends or distributing any cash or cash equivalents to Schlumberger and its subsidiaries that will not be subsidiaries of Sedco Forex after the spin-off; - incurring any indebtedness outside the ordinary course of business; and - engaging in any transaction with Schlumberger and its subsidiaries that will not be subsidiaries of Sedco Forex after the spin-off except on an arm's-length basis on terms no less favorable than Sedco Forex could obtain from a third party. RESTRUCTURING LIABILITIES Generally, Sedco Forex will be responsible for all liabilities associated with the assets and businesses it will hold when it is distributed to Schlumberger's shareholders, whether those liabilities arose before or arise after the spin-off date. Generally, Schlumberger will be responsible for all liabilities associated with the assets and businesses it will retain following the spin-off, whether arising before or after the spin-off date. Schlumberger will also be responsible for any liabilities directly arising out of or directly resulting from the transactions that are necessary to separate the Sedco Forex business, assets and liabilities from the rest of Schlumberger's business, assets and liabilities, except to the extent those liabilities would have directly arisen out of or directly resulted from the merger. In general, Schlumberger will be liable for taxes arising from the separation and spin-off, except for taxes that are first asserted by the local taxing authorities more than eight years after the spin-off or, in the case of customs duties, more than six years after the spin-off. INTERCOMPANY AGREEMENTS All existing intercompany agreements between Schlumberger and its subsidiaries that will not be subsidiaries of Sedco Forex after the spin-off, on the one hand, and Sedco Forex and its subsidiaries, on the other, will be terminated prior to the spin-off, except for those provided for in the distribution agreement. Sedco Forex and Schlumberger agreed not to solicit any active employees of the other for a period of two years after the date of the spin-off without the prior consent of the other party. Sedco Forex and Schlumberger also agreed to discontinue the use of any existing materials referencing the other party no later than six months after the date of the spin-off. Prior to the date of the pre-closing balance sheet, Sedco Forex will seek to terminate all obligations of Schlumberger or its subsidiaries, as guarantor, original tenant or primary obligor for Sedco Forex liabilities and any liens or encumbrances on the assets of Schlumberger or its subsidiaries related to the Sedco Forex liabilities. Likewise, prior to the date of the pre-closing balance sheet, Schlumberger will seek to terminate all obligations of Sedco Forex as guarantor, original tenant or primary obligor for the liabilities of Schlumberger or its subsidiaries and any liens or encumbrances on the assets of Sedco Forex related to the liabilities of Schlumberger or its subsidiaries. THE SPIN-OFF After the separation of Sedco Forex from Schlumberger, Schlumberger will distribute all outstanding Sedco Forex shares to Schlumberger's shareholders. Each Schlumberger shareholder will receive one Sedco Forex share for each share of Schlumberger common stock owned and will continue to own the same number of shares of Schlumberger common stock. No Sedco Forex shares will be issued with respect to shares of Schlumberger common stock held by Schlumberger in treasury. The spin-off is generally subject to the same conditions as the merger and will not be effected until the other conditions to the merger are fulfilled or 12

13 waived. See "-- Conditions to the Spin-Off and the Merger." If the parties terminate the merger agreement, the board of directors of Schlumberger may abandon the spin-off and terminate the distribution agreement. THE MERGER AGREEMENT On a day after the spin-off, Merger Sub, which is a wholly owned subsidiary of Transocean organized under the laws of the British Virgin Islands, will merge into Sedco Forex with Sedco Forex surviving as a wholly owned subsidiary of Transocean. The closing of the merger will take place promptly after all of the conditions to the merger described in "-- Conditions to the Spin-off and the Merger" are fulfilled or waived. The merger will be effective at the time Transocean and Schlumberger specify in the articles of merger they will file in the British Virgin Islands. In the merger, shareholders of Schlumberger who receive shares of Sedco Forex in the spin-off will receive, for each Sedco Forex share held, a number of Transocean ordinary shares equal to fifty-two forty-eighths times the number of diluted Transocean ordinary shares, divided by the number of diluted Sedco Forex shares, in each case as calculated immediately prior to the effectiveness of the merger. The number of diluted Transocean ordinary shares will be calculated according to the treasury method under U.S. generally accepted accounting principles and includes all shares issued at that time and a portion of the shares issuable pursuant to outstanding options to purchase Transocean ordinary shares and unvested restricted shares. The number of diluted Sedco Forex shares will be calculated on the same basis using the treasury method. All nonvested options to acquire shares of Schlumberger common stock held by Sedco Forex employees at the spin-off date will be treated as fully vested options to acquire shares of Sedco Forex common stock. The parties expect there will be approximately 101 million diluted Transocean ordinary shares and approximately 565 million diluted Sedco Forex shares at the time of the merger. Based on those estimates, each Sedco Forex share would be converted into approximately 0.194 of a Transocean ordinary share. If Transocean changes the number of its ordinary shares or Sedco Forex changes the number of its shares that are issued and outstanding, in either case as a result of a stock split, reverse stock split, stock dividend, recapitalization or other similar transaction, before the effectiveness of the merger and other than as provided for in the distribution agreement, Transocean and Schlumberger will adjust the exchange ratio appropriately. COVENANTS Interim Operations Transocean and Sedco Forex agreed to take or refrain from taking the actions described below from the date of the merger agreement, July 12, 1999, until the merger is completed or the merger agreement is terminated.

Any such proposal, offer or transaction may be referred to in this joint proxy statement/prospectus as a "Sedco Forex acquisition proposal." Sedco Forex and Schlumberger agreed not to cooperate with or engage in any discussions or negotiations concerning a Sedco Forex acquisition proposal. Sedco Forex and Schlumberger agreed to cease immediately any existing negotiations with any parties with respect to any of the foregoing. However, nothing contained in the merger agreement prevents Sedco Forex or Schlumberger from: - complying with Rule 14e-2 promulgated under the Exchange Act with regard to a Sedco Forex acquisition proposal; or 16

17 - before Schlumberger's shareholders approve the spin-off, providing information to or engaging in any negotiations with any person who has made an unsolicited bona fide Sedco Forex acquisition proposal with respect to all the outstanding Sedco Forex common stock or all or substantially all the assets of Sedco Forex or other unsolicited bona fide Sedco Forex acquisition proposal that, in the good faith judgment of a committee composed solely of outside directors of Schlumberger, taking into account the likelihood of financing and consummation, and based on the written advice of a financial adviser of recognized national reputation, is superior to the merger, if that committee, after consultation with its outside legal counsel, determines that the failure to do so would be inconsistent with its fiduciary obligations. Any information so provided is required to be provided pursuant to a confidentiality agreement at least as favorable to Sedco Forex and Schlumberger as the confidentiality agreement entered into with Transocean in connection with the merger. If Sedco Forex or Schlumberger intends to participate in any discussions or negotiations or to provide any information to any third party, Sedco Forex or Schlumberger is required to give prompt prior written notice to Transocean of each such action. Sedco Forex or Schlumberger is required to notify Transocean immediately in writing of any requests for information or the receipt of any Sedco Forex acquisition proposal, including the identity of the person or group (1) engaging in such discussions or negotiations, (2) requesting such information or (3) making such Sedco Forex acquisition proposal, and the material terms and conditions of any Sedco Forex acquisition proposal. Sedco Forex or Schlumberger is required to keep Transocean fully informed on a timely basis of the status and details, including any amendments or proposed amendments, of any such requests, Sedco Forex acquisition proposals or inquiries. Transocean will not permit any of its officers, directors, employees, agents or representatives, directly or indirectly, to solicit, initiate or encourage any inquiry, proposal or offer to merge, consolidate, purchase or otherwise acquire 15% or more of its consolidated assets or 15% or more of any class of its share capital. Any such proposal, offer or transaction may be referred to in this joint proxy statement/prospectus as a "Transocean acquisition proposal." Transocean agreed not to cooperate with or engage in any discussions or negotiations concerning a Transocean acquisition proposal. Transocean agreed to cease immediately any existing negotiations with any parties with respect to any of the foregoing. However, nothing contained in the merger agreement prevents Transocean from: - complying with Rule 14e-2 promulgated under the Exchange Act with regard to a Transocean acquisition proposal; or - before Transocean obtains the shareholder votes required in connection with the merger, providing information to or engaging in any negotiations with any person who has made an unsolicited bona fide Transocean acquisition proposal with respect to all the outstanding Transocean ordinary shares or all or substantially all the assets of Transocean that, in the good faith judgment of a committee composed solely of the outside directors of Transocean, taking into account the likelihood of financing and consummation, and based on the written advice of a financial advisor of recognized national reputation, is superior to the merger, if that committee, after consultation with its outside legal counsel, determines that the failure to do so would be inconsistent with its fiduciary obligations. Any information so provided is required to be provided pursuant to a confidentiality agreement at least as favorable to Transocean as the confidentiality agreement entered into with Schlumberger in connection with the merger. If Transocean intends to participate in any discussions or negotiations or provide any information to any third party, Transocean is required to give prompt prior written notice to Sedco Forex and Schlumberger of each such action. Transocean is required to notify Sedco Forex and Schlumberger immediately in writing of any requests for information or the receipt of any Transocean acquisition proposal, including the identity of the person or group (1) engaging in such discussions or negotiations, (2) requesting such information or (3) making such Transocean acquisition proposal, and the material terms and conditions of any Transocean acquisition proposal. Transocean is required to keep Sedco Forex and Schlumberger fully informed on a timely 17

18 basis of the status and details, including any amendments or proposed amendments, of any such requests, Transocean acquisition proposals or inquiries.

TERMINATION OF THE MERGER AGREEMENT Schlumberger, Sedco Forex and Transocean may terminate the merger agreement by mutual written consent. Schlumberger, Sedco Forex or Transocean may terminate the merger agreement if: - The parties have not consummated the merger by April 30, 2000, and the party desiring to terminate the merger agreement for this reason has not failed to perform or observe in any material respect any of its obligations under the merger agreement in any manner that caused the merger not to occur on or before that date. - At a meeting of the shareholders of Schlumberger, those shareholders do not approve the spin-off. - At a meeting of the shareholders of Transocean, those shareholders do not approve the required increase in Transocean's authorized ordinary share capital and the issuance of ordinary shares in the merger. - A U.S. federal or state court of competent jurisdiction or federal or state or non-U.S. governmental, regulatory or administrative agency or commission shall have issued an order, decree or ruling or taken 21

22 any other action permanently restraining, enjoining or otherwise prohibiting the merger, and such order, decree, ruling or other action shall have become final and unappealable. Sedco Forex or Schlumberger may terminate the merger agreement if: - Sedco Forex or Schlumberger concurrently enters into a binding written agreement concerning a transaction that constitutes a superior proposal for Sedco Forex after the board of directors of Sedco Forex or Schlumberger: - determines that proceeding with the merger would be inconsistent with its fiduciary obligations by reason of the superior proposal; and - elects to terminate the merger agreement effective before Schlumberger's shareholders have approved the spin-off. However, Sedco Forex or Schlumberger may not effect that termination: - unless and until Transocean receives at least one week's prior written notice from Sedco Forex of its intention to effect that termination; and - during that week, Schlumberger and Sedco Forex consider, and cause their respective financial and legal advisors to consider, any adjustment in the terms and conditions of the merger agreement that Transocean may propose. Any such termination of the merger agreement will not be effective until Schlumberger has paid to Transocean the $100 million termination fee described under "-- Expenses and Termination Fees." - Transocean or Merger Sub has materially breached any representation, warranty, covenant or agreement set forth in the merger agreement, or any representation or warranty of Transocean or Merger Sub shall have become materially untrue, in either case such that a condition to the merger would not be met, and such breach is not curable or, if curable, is not cured within 30 days after Sedco Forex gives written notice of the breach to Transocean, and Sedco Forex is not, at that time, in material breach of any representation, warranty, covenant or agreement set forth in the merger agreement. - the board of directors of Transocean shall have withdrawn or materially modified, in a manner adverse to Sedco Forex, its approval or recommendation of the merger or recommended a competing acquisition proposal for Transocean, or resolved to do so. - Schlumberger provides a timely objection notice to Transocean pursuant to the merger agreement concerning a Transocean structuring plan and, after receipt of such objection notice, Transocean transfers any asset or capital stock as provided in such structuring plan, and Schlumberger reasonably believes that implementation of the structuring plan creates significant risks of causing a Transocean material adverse effect. A "Transocean structuring plan" refers to a proposal by Transocean to transfer any of its material assets or capital stock or that of its subsidiaries to any other subsidiary of Transocean or to Transocean. Transocean may terminate the merger agreement if: - Transocean concurrently enters into a binding written agreement concerning a transaction that constitutes a superior proposal for Transocean after its board of directors: - determines that proceeding with the merger would be inconsistent with its fiduciary obligations by reason of the superior proposal; and - elects to terminate the merger agreement effective before Transocean's shareholders have approved the increase in its authorized ordinary share capital and issuance of its ordinary shares necessary in each case to complete the merger. 22

23 However, Transocean may not effect that termination: - unless and until Sedco Forex receives at least one week's prior written notice from Transocean of its intention to effect that termination; and - during that week, Transocean considers, and causes its financial and legal advisors to consider, any adjustment in the terms and conditions of the merger agreement that Sedco Forex may propose. Any such termination of the merger agreement will not be effective until Transocean has paid to Schlumberger the $100 million termination fee described under "-- Expenses and Termination Fees." - Sedco Forex or Schlumberger has materially breached any representation, warranty, covenant or agreement set forth in the merger agreement, or any representation or warranty of Sedco Forex or Schlumberger shall have become materially untrue, in either case such that a condition to the merger would not be met, and such breach is not curable or, if curable, is not cured within 30 days after Transocean gives written notice of the breach to Sedco Forex or Schlumberger, and Transocean is not, at that time, in material breach of any representation, warranty, covenant or agreement set forth in the merger agreement. - the board of directors of Schlumberger shall have withdrawn or materially modified, in a manner adverse to Transocean, its approval or recommendation of the spin-off or recommended a competing acquisition proposal for Sedco Forex, or resolved to do so. No party may terminate the merger agreement after the effectiveness of the merger. EXPENSES AND TERMINATION FEES Whether or not the merger is consummated, all costs and expenses incurred in connection with the merger agreement, the distribution agreement and the transactions contemplated by those agreements will be paid by the party incurring those expenses, except as expressly provided in those agreements. Transocean will bear no portion of any expenses incurred by Schlumberger or Sedco Forex in connection with the separation of Sedco Forex from the rest of Schlumberger's business or incurred by Schlumberger or Sedco Forex in connection with the spin-off. However, Transocean and Schlumberger will split evenly SEC filing fees, printing expenses and some regulatory fees paid by the parties in connection with the merger. Schlumberger is required to pay Transocean a cash termination fee of $100 million at the time of the termination if the merger agreement is terminated as follows: - by Schlumberger or Sedco Forex because the board of directors of Schlumberger or Sedco Forex determines that proceeding with the merger would be inconsistent with its fiduciary duties and concurrently enters into a binding agreement concerning a transaction that constitutes a superior proposal for Sedco Forex, or for Schlumberger where the proposal is conditioned on termination of the merger agreement; - by Schlumberger, Sedco Forex or Transocean because Schlumberger's shareholders do not approve the spin-off after the public announcement of a competing acquisition proposal for Sedco Forex; or - by Transocean because the board of directors of Schlumberger has withdrawn or materially modified its approval or recommendation of the spin-off or recommended a competing acquisition proposal for Sedco Forex after the public announcement of that competing proposal or receipt by Schlumberger's or Sedco Forex's board of directors of a competing acquisition proposal for Sedco Forex, whether or not that proposal is still pending or has been consummated. 23

24 Transocean is required to pay Schlumberger a cash termination fee of $100 million at the time of the termination if the merger agreement is terminated as follows: - by Transocean because the board of directors of Transocean determines that proceeding with the merger would be inconsistent with its fiduciary duties and concurrently enters into a binding agreement concerning a transaction that constitutes a superior proposal for Transocean; - by Schlumberger, Sedco Forex or Transocean because Transocean's shareholders do not approve the proposed increase in Transocean's authorized ordinary share capital or the issuance of its ordinary shares in the merger after the public announcement of a competing acquisition proposal for Transocean; or - by Schlumberger or Sedco Forex because the board of directors of Transocean has withdrawn or materially modified its approval or recommendation of the proposals for Transocean's shareholders, passage of which is necessary to complete the merger, or recommended a competing acquisition proposal for Transocean after the public announcement of that competing proposal or receipt by Transocean's board of directors of a competing acquisition proposal for Transocean, whether or not that proposal is still pending or has been consummated. If the merger agreement is terminated because the shareholders of Schlumberger do not approve the spin-off and there was no public announcement of a competing acquisition proposal for Sedco Forex before the shareholders' vote, then Schlumberger is required to pay Transocean a fee of $10 million to reimburse it for its costs and expenses incurred in connection with the merger and related transactions. If the merger agreement is terminated because the shareholders of Transocean do not approve the proposed increase in Transocean's authorized ordinary share capital or the issuance of the ordinary shares in the merger and there was no public announcement of a competing acquisition proposal for Transocean before the shareholders' vote, then Transocean is required to pay Schlumberger a fee of $10 million to reimburse it for its costs and expenses incurred in connection with the merger and related transactions. AMENDMENT The parties may amend the merger agreement, by action taken or authorized by their boards of directors, at any time before or after approval by the shareholders of the parties of the matters presented in connection with the merger. After any shareholder approval, the parties may not amend the merger agreement if the law requires further approval by those shareholders, unless such further approval is obtained. Schlumberger and Sedco Forex may amend the distribution agreement, by action taken or authorized by their boards of directors, at any time before or after approval by Schlumberger's shareholders, but any amendment must be consented to by Transocean in writing. EMPLOYEE MATTERS AGREEMENT Before the date on which Schlumberger distributes the capital stock of Sedco Forex to Schlumberger's shareholders, Schlumberger and Sedco Forex will enter into a definitive employee matters agreement concerning personnel and employee benefit matters that will incorporate the basic terms and conditions set forth below. Schlumberger and Sedco Forex agreed to amend, modify and/or terminate, as necessary, the various employee benefit plans, arrangements, policies and practices of the parties, or to create new employee benefit plans, arrangements, policies and practices, to transition successfully the Sedco Forex employees from Schlumberger to Sedco Forex and to accomplish the transactions contemplated in the merger agreement and distribution agreement. 24

Sedco Forex will transfer to Schlumberger or its subsidiaries, other than Sedco Forex or a Sedco Forex subsidiary, all employees of Schlumberger and its subsidiaries other than Sedco Forex employees described in the first sentence of this paragraph. For a period of one year after the spin-off date, but not later than December 31, 2000, Transocean Sedco Forex generally will maintain, for Sedco Forex employees, benefits and benefit arrangements that, in the aggregate, are substantially comparable to the benefits and benefit arrangements provided by Schlumberger and its subsidiaries to Sedco Forex employees as of the date of the distribution agreement.

Sedco Forex generally will assume all other employment and benefit-related liabilities of the Sedco Forex employees not specifically allocated to Schlumberger under the employee matters agreement, generally as described above. PARTICIPATION IN SCHLUMBERGER PLANS Effective as of the spin-off date, Sedco Forex will adopt the Schlumberger International Staff Pension Plan as a participating employer for the benefit of all eligible Sedco Forex employees, including those who are participating in the Schlumberger International Staff Pension Plan immediately before the spin-off date. Sedco Forex will maintain its status as a participating employer, including all rights and responsibilities associated with such status through December 31, 2000. Effective as of the spin-off date, Sedco Forex may, at its option, adopt any of the employment and benefit arrangements maintained by Schlumberger that cover Sedco Forex employees as a participating employer for the benefit of all eligible Sedco Forex employees, including those employed after the spin-off date, and may maintain such status as a participating employer, including all rights and responsibilities associated with such status, through December 31, 2000. Sedco Forex will pay the employer contributions or costs for each Sedco Forex employee required under any Schlumberger plan in which Sedco Forex participates. 25

26 STOCK OPTIONS As of the effective time of the spin-off, all nonvested options to purchase Schlumberger common stock held by Sedco Forex employees at such time will terminate by their terms. Upon completion of the merger, the Sedco Forex employees who held these options will be granted fully vested options to acquire Transocean Sedco Forex ordinary shares. The number of Transocean Sedco Forex ordinary shares for which a newly granted option will be exercisable will equal the number of Schlumberger shares subject to the terminated Schlumberger option times a fraction, the numerator of which is the closing price of Schlumberger common stock at the close of trading on the day immediately prior to the spin-off date, determined without regard to the spin-off of Sedco Forex, and the denominator of which is the price of a Transocean ordinary share at the close of trading on the day immediately prior to the spin-off date. The exercise price of each such option will be the price of a Transocean ordinary share at the close of trading on that date times a fraction, the numerator of which is the exercise price under the terminated Schlumberger option and the denominator of which is the price of Schlumberger common stock at the close of trading on the day immediately prior to the spin-off date, determined without regard to the spin-off of Sedco Forex. The formula will likely require Transocean Sedco Forex to grant some of these options with exercise prices below fair market value. Transocean Sedco Forex will grant these options with an exercise price below fair market value at the date of grant to the extent a below market price would be required by application of the exercise price adjustment formula. However, French-based employees of Sedco Forex who are eligible to receive new Transocean Sedco Forex options will be granted options with an exercise price equal to the fair market value of Transocean Sedco Forex ordinary shares at the date of grant, even if the application of the adjustment formula otherwise would result in an exercise price below the market price of Transocean Sedco Forex ordinary shares at that date. To compensate these holders for the resulting diminution in value, Transocean Sedco Forex will grant additional options with a fair market value exercise price, the appropriate number of which will be determined by valuing those options according to the Black-Scholes option pricing models and related assumptions deemed reasonable by Transocean Sedco Forex. The Transocean Sedco Forex options will be granted outside of the Long-Term Incentive Plan, but will be subject to substantially identical terms and conditions. Transocean anticipates that following the merger it will adopt a stand-alone plan pursuant to which these newly granted options will be administered. This plan would be substantially identical to Transocean's existing Long-Term Incentive Plan, except the new plan would permit Transocean Sedco Forex to grant these options with an exercise price below fair market value at the date of grant to the extent a below market price would be required by application of the exercise price adjustment formula set forth in the employee matters agreement. All vested options to purchase Schlumberger common stock held by Sedco Forex employees will remain outstanding as options to purchase Schlumberger common stock for the period following completion of the merger established by Schlumberger's stock option plan, which is generally 90 days after the completion of the merger. Options to acquire Schlumberger common stock that are held by persons other than Sedco Forex employees will remain options to purchase Schlumberger shares. The exercise price and number of shares of Schlumberger common stock purchasable upon exercise under all Schlumberger options outstanding immediately after completion of the merger, including those vested options held by Sedco Forex employees, will be equitably adjusted to reflect the approximate decrease in the value of Schlumberger common stock as a result of the spin-off. Shortly after the transactions are completed, Schlumberger will communicate with affected optionholders regarding how these Schlumberger options will be adjusted. OTHER TRANSITIONAL EMPLOYEE MATTERS Sedco Forex will assume all worker's compensation liability of Sedco Forex employees after the spin-off date. Schlumberger will administer all Sedco Forex employees' worker's compensation claims that arose up to the spin-off date for a period of five years after the spin-off date. However, Sedco Forex will pay all worker's compensation payments that become due after the spin-off date. Schlumberger will provide all administrative or professional services required for the operation of any Sedco Forex plans. Sedco Forex will reimburse Schlumberger for the cost of such services. 26

27 BUSINESS OF SEDCO FOREX The following summary describes Sedco Forex's business as it is expected to be constituted after its separation from Schlumberger and at the time of its spin-off to Schlumberger's shareholders. Sedco Forex is a leading international provider of offshore contract drilling services for oil and gas exploration, development and production. Sedco Forex currently owns, has an ownership interest in or operates 40 mobile offshore drilling rigs. Sedco Forex's fleet consists of three fourth-generation semisubmersibles, twenty second- and third-generation semisubmersibles, one first-generation semisubmersible, two drillships, ten jackup rigs and four tenders. Sedco Forex also has under construction three Sedco Express-class semisubmersibles, the Sedco Express, Cajun Express and Sedco Energy, and one independent-leg cantilevered jackup rig, the Trident 20. In addition, the fleet includes one multi-purpose service jackup rig, six swamp barges and two land drilling rigs. Sedco Forex contracts these drilling rigs, related equipment and work crews primarily on a dayrate basis to drill oil and gas wells. Sedco Forex also provides additional drilling services, including well intervention and management of third-party well service activities. Sedco Forex Holdings Limited is organized as an international business company under the laws of the British Virgin Islands in 1990. Its registered office in the British Virgin Islands is located at Citco B.V.I. Limited, Citco Building, Wickhams Cay, P. O. Box 662, Road Town, Tortola, British Virgin Islands. DRILLING RIG TYPES Sedco Forex principally uses five types of drilling rigs: - semisubmersibles - drillships - jackups - tenders - swamp barges Semisubmersibles are floating vessels that can be submerged such that a substantial portion of the lower hull is below the water surface during drilling operations. They are well suited for operations in rough water conditions. Fourth-generation semisubmersibles are those that were built after the mid-eighties or have been recently upgraded and have larger physical size than other semisubmersibles, harsh environment capability, variable deck load capability of greater than 4,000 metric tons and superior motion characteristics. Fourth-generation semisubmersibles, which are generally rated for drilling in water depths of over 4,000 feet, are often considered the most suitable units for operations in deep water and harsh environments or for development drilling that requires larger variable loads and the ability to handle large pieces of subsea equipment. Sedco Forex is constructing three newbuild semisubmersibles based on Sedco Forex's proprietary Sedco Express design. See "Sedco Forex Management's Discussion and Analysis of Financial Condition and Results of Operations." Drillships are generally self-propelled and designed to drill in the deepest waters in which offshore drilling rigs currently operate. Shaped like conventional ships, they are the most mobile of the major rig types. Sedco Forex's drillships are either dynamically positioned, which allows them to maintain position without anchors through the use of their onboard propulsion and station-keeping systems, or are operated in a moored configuration. Jackup rigs are mobile self-elevating drilling platforms equipped with legs that can be lowered to the ocean floor until a foundation is established to support the drilling platform. Once a foundation is established, the drilling platform is then jacked further up the legs so that the platform is above the highest expected waves. The rig hull includes the drilling rig, jacking system, crew quarters, loading and unloading facilities, 27

28 storage areas, helicopter landing deck and related equipment. They are generally suited for water depths of 400 feet or less. Tenders are usually barges or semisubmersibles that are not self-propelled, but can be moored alongside a platform, and contain quarters, mud pits, mud pumps, power generation and other equipment. Tenders allow smaller, less costly platforms to be used for development projects. Self-erecting tenders carry their own derrick equipment set and have a crane capable of erecting it on the platform, thereby eliminating the cost associated with a separate derrick house and related equipment. Tenders are generally suited for water depths of 460 feet or less. Swamp barges are usually not self-propelled, but can be moored alongside a platform, and contain quarters, mud pits, mud pumps, power generation and other equipment. Like tenders, swamp barges allow smaller, less costly platforms to be used for development projects. Swamp barges often carry their own derrick equipment set and crane. Swamp barges are generally suited for water depths of 25 feet or less. Sedco Forex's drilling equipment is suitable for both exploration and development drilling, and Sedco Forex is normally engaged in both types of drilling activity. Sedco Forex's drilling rigs are mobile and can be moved to new locations in response to client demand. All of the Sedco Forex offshore drilling units are designed for operations away from port for extended periods of time and have living quarters for the crews, a helicopter landing deck and storage space for pipe and drilling supplies. FLEET ENHANCEMENTS AND UPGRADES Sedco Forex performed life enhancement and upgrade projects during 1999 for the Trident IV jackup rig and the Sedco 709 semisubmersible. Sedco Forex spent in excess of $75 million on these two projects to increase significantly the capacity, marketability and dayrates of these two rigs. Both of these rigs are currently under contract.

(b) Expiration dates represent Sedco Forex's current estimate of the earliest date the contract for each rig is likely to expire. Some rigs have two contracts in continuation, so the second line shows the estimated earliest availability. Some contracts have options under which the rigs could continue to work on the same terms after the estimated expiration. (c) The Cajun Express is expected to be operational in the second quarter of 2000. The contract provides for termination if the rig is not delivered by March 31, 2001. (d) Operated under a bareboat charter with the rig's owner, Sea Wolf Drilling Limited, in which Schlumberger has an indirect 25% interest. See Note 12 to the Combined Financial Statements of Sedco Forex. Although the owner of the remaining 75% interest in the venture has, to date, not consented to the transfer of Schlumberger's interest, Schlumberger is taking steps to achieve resolution of this issue. The 29

30 parties cannot predict whether Schlumberger's ownership interest in the venture or the right to use these rigs will be transferred to Transocean Sedco Forex or whether an alternative resolution acceptable to Transocean will be achieved. (e) Operated under a management contract with the rig's owner. (f) Under contract with Petrobras for the period from third quarter 2000 to third quarter 2008. (g) Also under contract with BHP for the period from December 1999 to May 2000. (h) Under contract with Japex for January 2000 and Inpex for February 2000. (i) The Sedco Energy is expected to be operational in the first quarter of 2000. If delivery of the rig is delayed beyond the contract delivery date, the contract provides for a reduction in its term equivalent to the period of delayed delivery. (j) The Sedco Express is expected to be operational in the first quarter of 2000. The contract provides for termination if the rig is not delivered by May 28, 2000. (k) Considered a multi-purpose service vessel capable of being used for workovers or associated services. (l) Owned by an unrelated third party and leased by Sedco Forex. Sedco Forex has an option to purchase, and the owner has an option to cause Sedco Forex to purchase, the rig. (m) Owned by a joint venture owned more than 50% by Sedco Forex. The Trident 20 is expected to be operational in the fourth quarter of 2000. The contract provides for termination if the rig is not delivered by February 12, 2002. (n) Currently engaged in scientific geological coring activities; owned by a joint venture owned 50% by Sedco Forex. Upon the expiration of existing contracts, there can be no assurance that such contracts will be renewed or extended, that new contracts will be available or, if contracts are available, that they will provide revenues adequate to cover all fixed and variable costs associated with the rigs. As of September 30, 1999, Sedco Forex's rigs, excluding rigs under construction, were located in: - the United Kingdom (7 units); - Ireland (1 unit); - Africa-Mediterranean Sea (18 units); - Middle East-India (2 units); - Asia (16 units); - Brazil (3 units); and - Canada (1 unit). The Joides Resolution is contracted for a worldwide research program and as of September 30, 1999 was in a shipyard in Singapore undergoing an upgrade. It is expected to be back in operation in mid-November 1999. DRILLING CONTRACTS Sedco Forex's contracts to provide offshore drilling services are individually negotiated and vary in their terms and provisions. Sedco Forex obtains most of its contracts through competitive bidding against other contractors. Drilling contracts generally provide for payment on a dayrate basis, with higher rates while the drilling unit is operating and lower rates for periods of mobilization or when drilling operations are interrupted or restricted by equipment breakdowns, adverse environmental conditions or other conditions beyond the control of Sedco Forex. Sedco Forex typically does not drill turnkey wells, under which the contractor agrees to drill a well to a specified depth for a fixed price. 30

31 A dayrate drilling contract generally extends over a period of time covering either the drilling of a single well or group of wells or covering a stated term. These contracts typically can be terminated by the client in the event the drilling unit is destroyed or lost, or if drilling operations are suspended for a specified period of time as a result of a breakdown of major equipment or, in some cases, due to other events beyond the control of either party. In addition, the drilling contracts for Sedco Forex's newbuild rigs contain termination or term reduction provisions tied to late delivery of these units. The contract term in many instances may be extended by the client exercising options for the drilling of additional wells or for an additional term. In reaction to depressed market conditions, Sedco Forex's clients may seek renegotiation of firm drilling contracts to reduce their obligations or may seek to terminate their contracts by paying a termination fee to Sedco Forex. SIGNIFICANT CLIENTS During the past five years, Sedco Forex has engaged in offshore drilling for most of the world's leading international oil companies or their affiliates, as well as for many government-controlled and independent oil companies. During this period, Sedco Forex's principal clients have included Shell, Chevron, Total, Woodside, Petrobras, Unocal and Elf. During 1998, Shell accounted for approximately 19 percent of Sedco Forex's consolidated operating revenues. No other unaffiliated client accounted for ten percent or more of Sedco Forex's 1998 consolidated operating revenues. The loss of any of these major clients could, at least in the short term, have a material adverse effect on Sedco Forex. INDUSTRY CONDITIONS AND COMPETITION Sedco Forex's business depends on the level of activity in offshore oil and gas exploration, development and production in markets worldwide. Oil and gas prices, market expectations of potential changes in these prices and a variety of political and economic factors significantly affect this level of activity. Oil and gas prices are extremely volatile and are affected by numerous factors, including: - 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 of non-OPEC countries; - the policies of the various governments regarding exploration and development of their oil and gas reserves; - advances in exploration and development technology; and - the political environment of oil-producing regions. The offshore contract drilling industry is highly competitive with numerous industry participants, none of which has a dominant market share. Some of Sedco Forex's competitors may have greater resources than Sedco Forex. 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. Sedco Forex's industry has historically been cyclical. There have been periods of high demand, short rig supply and high dayrates, followed by periods of lower demand, excess rig supply and low dayrates. The industry is currently in a period of low demand, and Sedco Forex is unable to predict when the market will change and if so, to what extent. In addition, rig availability has increased as a result of contract expirations and construction by other drilling contractors of new rigs that are competing with Sedco Forex's rigs. Periods of excess rig supply intensify the competition in the industry and often result in rigs being idled for long periods of time. 31

32 Sedco Forex requires highly skilled personnel to operate and provide technical services and support for its drilling units. To the extent demand for drilling services and the size of the worldwide industry fleet increase, shortages of qualified personnel similar to those experienced in 1996-97 could arise, creating upward pressure on wages. As of September 30, 1999, Sedco Forex had four new rigs in shipyards under construction. These construction projects are subject to the risks of delay or cost overruns inherent in any large construction project resulting from numerous factors, including the following: - shipyard unavailability; - shortages of equipment, materials or skilled labor; - unscheduled delays in the delivery of ordered materials and equipment; - engineering problems, including those relating to the commissioning of newly designed equipment; - work stoppages; - weather interference; - unanticipated cost increases; and - difficulty in obtaining necessary permits or approvals. These factors may contribute to cost variations and delays in the delivery of Sedco Forex's drilling units under construction. Delays in delivery of these units would result in delays in contract commencements, resulting in a loss of revenue to Sedco Forex. These delays may also cause customers to terminate the drilling contracts for these rigs pursuant to late delivery termination clauses. In the event of termination of a drilling contract for one of these rigs, it is unlikely that Sedco Forex would be able to secure a replacement contract on as favorable terms. MARKETS Rigs can be moved from one region to another, but the cost of moving a rig and the availability of rig-moving vessels may cause the supply and demand balance to vary somewhat between regions. However, significant variations between regions do not tend to exist long-term because of rig mobility. Rig mobility causes markets to be defined more by water depth capability than region. Sedco Forex has the capability of drilling in water depths from as shallow as a few feet with its swamp barges to as deep as 6,500 feet with its Sedco 707 semisubmersible. In addition, each of Sedco Forex's three newbuild semisubmersibles will be capable of drilling in water depths of at least 7,500 feet. In recent years, there has been increased emphasis by oil companies on exploring for hydrocarbons in deeper waters. This is, in part, because of technological developments that have made such exploration more feasible and cost-effective. Shallow water regions have been developed much more than deep water regions because these regions are more accessible and operations there are less costly to conduct. OPERATING RISKS Sedco Forex's operations are subject to the usual hazards inherent in the drilling of oil and gas wells, such as blowouts, loss of well control, punchthroughs, cratering or fires, the occurrence of which could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury or death to rig personnel. 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 operations 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 Sedco Forex's operations, particularly through oil spillage or extensive uncontrolled fires. 32

33 Sedco Forex maintains broad insurance coverage, including insurance against general and marine third party liabilities. Sedco Forex's offshore drilling equipment is insured by all risks physical damage insurance policies, which cover against marine and other perils, including losses due to capsizing, grounding, collision, fire, lightning, hurricanes, wind, storms, action of waves, punchthroughs, cratering, blowouts, explosions and war risks. Sedco Forex also carries employer's liability and other insurance customary in the offshore contract drilling business. Consistent with standard industry practice, Sedco Forex's clients generally assume, and indemnify Sedco Forex against, well control and subsurface risks under dayrate contracts. These risks are those associated with the loss of control of a well, such as blowout or cratering, the cost to regain control or redrill the well and associated pollution. Sedco Forex typically does not carry insurance against such risks under dayrate contracts. However, Sedco Forex cannot guarantee that these clients will necessarily be financially able to indemnify it against all these risks. Sedco Forex believes it is adequately insured in accordance with industry standards against normal risks in its operations; however, such insurance coverage may not in all situations provide sufficient funds to protect Sedco Forex from all liabilities that could result from its drilling operations. Sedco Forex insures its rigs on an agreed value basis that is at least equal to the net book value of the rig and is regularly reviewed and modified for each individual rig based on market value, technology, such as deep water or dynamic positioning capability, utilization, dayrate and earnings potential. This means that some rigs are not insured for replacement value. Business interruption is not generally insured against, except in the event of total loss where an element of lost earnings can be included in the total insured value of the rig. This "top up" to the insured value is added where considered appropriate. Accordingly, the occurrence of a casualty or loss against which Sedco Forex is not fully insured could have a material adverse effect on Sedco Forex's financial position and results of operations. Sedco Forex is subject to liability under various environmental laws and regulations. See "-- Regulation." Generally, Sedco Forex has been able to obtain some degree of contractual indemnification pursuant to which Sedco Forex's client agrees to protect and indemnify Sedco Forex from liability for pollution, well and environmental damages; however, there is no assurance that Sedco Forex can obtain such indemnities in all of its contracts or that, in the event of extensive pollution and environmental damages, the clients will have the financial capability to fulfill their contractual obligations to Sedco Forex. Also, these indemnities may not be enforceable in all instances. For some contracts where the risk allocation or counterparty risk exposure is considered high, Sedco Forex can purchase additional insurance such as "operators extra expense insurance" against well control risks. INTERNATIONAL OPERATIONS Sedco Forex operates in various regions throughout the world that expose Sedco Forex to various political and other uncertainties, including risks of: - war and civil disturbances; - expropriation of equipment; - the inability to repatriate income or capital; and - changing taxation policies. Sedco Forex is protected to a substantial extent against capital loss, but generally not loss of revenue, from most of these risks through insurance, indemnity provisions in its drilling contracts or both. As of September 30, 1999, all areas in which Sedco Forex was operating were covered by existing insurance policies. Sedco Forex's operations are also subject to significant government regulation in different jurisdictions. 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 33

34 may adversely affect Sedco Forex's ability to compete. Sedco Forex expects to continue its efforts to structure its operations in order to remain competitive in the international markets. Another risk inherent in Sedco Forex's operations is the possibility of currency exchange losses where revenues are received and expenses are paid in nonconvertible currencies. Sedco Forex may also incur losses as a result of an inability to collect revenues because of a shortage of convertible currency available to the country of operations. Sedco Forex seeks to limit these risks by structuring contracts such that compensation is made in freely convertible currencies and, to the extent possible, by limiting acceptance of blocked currencies to amounts that match its expense requirements in local currency. REGULATION Sedco Forex's 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 affected by changing tax and other laws relating to the energy business generally. International contract drilling operations are subject to various laws and regulations in countries in which Sedco Forex operates, including laws and regulations relating to equipping and operating of drilling units, currency conversions and repatriation, oil exploration and development, taxation of offshore earnings and earnings of expatriate personnel and use of local employees and suppliers by foreign contractors. Governments in some countries have become increasingly active in regulating and controlling the ownership of concessions and companies holding concessions, the exportation of oil and other aspects of the oil industries in their countries. In addition, government action, including initiatives by OPEC, may continue to cause oil 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. Some of the countries in whose waters Sedco Forex is presently operating or may operate in the future have regulations covering the discharge of oil and other contaminants in connection with drilling operations. In some cases, Sedco Forex, as an operator of mobile offshore drilling units, may be liable for damages and costs incurred in connection with oil spills for which it is held responsible, subject to certain limitations. Laws and regulations protecting the environment have become more stringent in recent years, and may in certain circumstances impose "strict liability," rendering a person liable for environmental damage without regard to negligence or fault on the part of such person. Such laws and regulations may expose Sedco Forex 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 such acts were performed. The application of these requirements or the adoption of new requirements could have a material adverse effect on Sedco Forex's financial position and results of operations. Sedco Forex believes that it has conducted its operations in substantial compliance with applicable environmental laws and regulations governing its activities. Although significant capital expenditures may be required to comply with such governmental laws and regulations, such compliance has not materially adversely affected the earnings or competitive position of Sedco Forex. EMPLOYEES As of September 30, 1999, Sedco Forex had approximately 4,500 employees. Sedco Forex requires highly skilled personnel to operate its drilling units. As a result, Sedco Forex conducts extensive personnel recruiting, training and safety programs. On a worldwide basis, Sedco Forex had approximately 13 percent of its employees working under collective bargaining agreements at September 30, 1999. Some of those agreements have expired and negotiations are ongoing for new contracts. Sedco Forex has not experienced any work stoppages as a result of these expirations and negotiations. Sedco Forex believes it has good relations with its employees. 34

35 PROPERTIES Sedco Forex owns or leases office space or other facilities in most of the countries where it conducts operations. Sedco Forex does not consider any of these facilities to be material to its overall operations. LEGAL PROCEEDINGS Global Marine Drilling Company initiated an arbitration proceeding in London in December 1997 against Sedco Forex. Global Marine alleges a claim for approximately $85 million against Sedco Forex for an alleged late return of a chartered rig and for breach of maintenance obligations under the charter. In February 1998, the tribunal held that the charter expired January 20, 1998, plus time for physical delivery, meaning Sedco Forex is liable to Global Marine for the "market dayrate" from that time until actual delivery in 1998. It is expected that the balance of the proceedings, including the final determination of any damages, will take place in 2000. On October 15, 1999, an arrestment of the Sedco Forex rig, Sovereign Explorer, was executed in connection with the proceedings. The rig is currently idle, and Sedco Forex does not expect this action to have any impact on the case or the operations of the rig. Sedco Forex disputes the allegations and arrestment and is vigorously defending the case. Sedco Forex does not expect that the ultimate liability, if any, resulting from the matter will have a material adverse effect on its business, financial position or results of operations. RIGCO North America, LLC, a subsidiary of Tatham Offshore Inc., filed a lawsuit in Texas state court in July 1999 asserting various claims against Sedco Forex in connection with shipyard and rig management contracts for two rigs managed on behalf of RIGCO. RIGCO alleges breach of contract, negligence and fraud and claims damages of approximately $51 million, plus exemplary damages, attorney's fees and other unspecified damages. In August 1999, RIGCO filed for voluntary bankruptcy protection in bankruptcy court in Texas. As part of the bankruptcy proceedings, RIGCO filed a preference action against Sedco Forex in September 1999. RIGCO seeks to avoid alleged transfers of approximately $4.2 million to Sedco Forex and to have those funds returned to the RIGCO bankruptcy estate. Sedco Forex disputes the allegations and is vigorously defending the case. Sedco Forex does not expect that the liability, if any, resulting from the matter will have a material adverse effect on its business, financial position or results of operations. The Indian Customs Department, Mumbai, filed a "show cause notice" against Sedco Forex and various other parties on July 8, 1999. The show cause notice alleges that the entry into India and other subsequent movements of a rig operated by Sedco Forex constituted imports and exports for which proper customs procedures were not followed and customs duties should have been paid, and seeks payment of customs duties, with interest and penalties, and confiscation of the rig. Sedco Forex has filed a response to the show cause notice. Hearings on this matter are continuing, and Sedco Forex expects an initial phase adjudication by the Customs Department by the first quarter of 2000. Sedco Forex disputes the allegations and is vigorously defending the case. Sedco Forex does not expect that the ultimate liability, if any, resulting from the matter will have a material adverse effect on its business, financial position or results of operations. Sedco Forex and its subsidiaries are involved in various other legal proceedings and claims that have arisen in the ordinary course of business. Sedco Forex believes that the ultimate liability, if any, resulting from such matters will not have a material adverse effect on its business, financial position, or results of operations. Sedco Forex is involved in certain other legal proceedings with respect to which Schlumberger has agreed to indemnify Sedco Forex against all costs and expenses and any ultimate liability that may be incurred. 35

37 SEDCO FOREX MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following information should be read in connection with the information contained in Sedco Forex's combined financial statements and the notes thereto included elsewhere in this joint proxy statement/prospectus. As used in this discussion, the term "Sedco Forex" refers to the historical offshore contract drilling service business of Schlumberger Limited that is to be spun off and merged with Transocean and to that business as consolidated under Sedco Forex Holdings Limited from and after the time of the spin-off. OVERVIEW Sedco Forex is a leading international provider of offshore contract drilling services for offshore oil and gas exploration, development and production. Sedco Forex currently owns, has an ownership interest in or operates 40 mobile offshore drilling rigs. Sedco Forex's fleet consists of three fourth-generation semisubmersibles, twenty second- and third-generation semisubmersibles, one first-generation semisubmersible, two drillships, ten jackup rigs and four tenders. Sedco Forex also has under construction three Sedco Express-class semisubmersibles, the Sedco Express, Cajun Express and Sedco Energy, and one independent-leg cantilevered jackup rig, the Trident 20. In addition, the fleet includes one multi-purpose service jackup rig, six swamp barges and two land drilling rigs. Sedco Forex contracts these drilling rigs, related equipment and work crews primarily on a dayrate basis to drill oil and gas wells. Sedco Forex also provides additional drilling services, including well intervention and management of third-party well service activities. OPERATING RESULTS Comparative data relating to Sedco Forex's operating results for the three years ended December 31, 1998, 1997 and 1996 and for the six months ended June 30, 1999 and 1998 are summarized below. The results of interim periods are not necessarily indicative of a full year's operations. SIX MONTHS ENDED JUNE 30, YEAR ENDED DECEMBER 31, ----------------- -------------------------- 1999 1998 1998 1997 1996 ------- ------- -------- ------ ------ (IN MILLIONS) (UNAUDITED) REVENUE: Operating...................................... $ 352 $534.4 $1,090.5 $891.3 $663.2 Interest and other income...................... 6.7 3.3 8.8 8.3 8.1 ------ ------ -------- ------ ------ 358.3 537.7 1,099.3 899.6 671.3 EXPENSES: Cost of services............................... 297.1 329.3 674.7 561.8 476.3 Research and engineering....................... 6.3 6.1 11.3 9.8 10.2 General and administrative..................... 8.4 12.3 26.3 15.9 13.8 Interest expense, net.......................... 6.9 9.9 13.0 19.6 7.9 ------ ------ -------- ------ ------ Income before taxes.............................. 39.6 180.1 374.0 292.5 163.1 Income taxes..................................... (0.9) (21.8) (32.4) (32.0) (15.6) ------ ------ -------- ------ ------ Net income............................. $ 38.7 $158.3 $ 341.6 $260.5 $147.5 ====== ====== ======== ====== ====== Six months ended June 30, 1999 compared to six months ended June 30, 1998 Operating revenues for the six months ended June 30, 1999 were $352 million compared to $534 million for the same period in 1998, a decrease of $182 million or 34 percent. The decrease resulted primarily from decreased demand in the worldwide drilling market as a direct consequence of depressed oil prices in 1998 and early 1999. As a result, average utilization for the first six months of 1999 fell to 75 percent compared to an average of 96 percent for the same period in 1998. In addition, average dayrates for the first six months of 1999 fell to approximately $61,000 compared to approximately $67,000 for the same period in 1998. 37

38 Cost of services for the six months ended June 30, 1999 was $297 million compared to $329 million for the same period in 1998, a decrease of $32 million or 10 percent. The decrease resulted primarily from reduced rig activity in 1999 due to the decline in demand and resulting oversupply of rigs in the market. A large portion of Sedco Forex's cost of services consists of depreciation and employee-related costs and is fixed or only semi-variable. Accordingly, cost of services does not vary in direct proportion to activity. Cost of services for the six months ended June 30, 1999 also includes charges totaling $42 million in respect of severance liabilities and provisions for contractual disputes. Research and engineering expense for the six months ended June 30, 1999 was $6 million compared to $6 million for the same period in 1998. In both periods, approximately $2 million of research and engineering expense was allocated by Schlumberger to Sedco Forex. This allocation is dependent on a number of factors, including the nature and scale of research and engineering projects, the level of central costs and the proportion of Sedco Forex's revenues to Schlumberger's worldwide group revenues. Accordingly, while the allocation methods are considered to be reasonable, the level of research and engineering expenses may not be indicative of ongoing costs for Sedco Forex upon completion of the spin-off from Schlumberger and the merger with Transocean. General and administrative expense for the six months ended June 30, 1999 was $8 million compared to $12 million for the same period in 1998, a decrease of $4 million or 33 percent. The decrease resulted from cost reduction measures taken in response to reduced activity levels and the lower allocation of central overhead due to Sedco Forex's lower revenues. General and administrative expense includes an allocation by Schlumberger to Sedco Forex that amounts to approximately $3 million for the six months ended June 30, 1999 and $5 million for the same period in 1998. The amount allocated by Schlumberger is dependent on a number of factors, including the level of central costs and the proportion of Sedco Forex's revenues to Schlumberger's worldwide group revenues. Accordingly, while the allocation methods are considered to be reasonable, the level of general and administrative expenses may not be indicative of ongoing costs for Sedco Forex upon completion of the spin-off from Schlumberger and the merger with Transocean. Interest expense for the six months ended June 30, 1999 was $7 million compared to $10 million for the same period in 1998, a decrease of $3 million or 30 percent. The net decrease includes an increase in gross interest expense for the first six months of 1999 to $17 million compared to $11 million for the same period of 1998. This increase resulted primarily from interest incurred on loans to finance newbuild construction projects. The increase was more than offset by the capitalization of $12 million of interest for the period ended June 30, 1999 in respect of construction projects compared to the capitalization of only $2 million for the comparable 1998 period. Income tax expense for the six months ended June 30, 1999 was $1 million compared to $22 million for the same period in 1998, a decrease of $21 million or 95 percent. The decrease resulted primarily from the reduction in activity and dayrates in countries where taxes are charged on a "deemed profit" basis (equivalent to a fixed percentage of revenue) coupled with the tax effect of the charges included in cost of services. Net income for the six months ended June 30, 1999 was $39 million compared to $158 million for the same period in 1998, a decrease of $119 million or 75 percent. The decrease resulted primarily from the significant reduction in revenues compared to 1998, as well as the impact of charges in the first quarter of 1999. 1998 compared to 1997 Operating revenues for the year ended December 31, 1998 were $1,091 million compared to $891 million for 1997, an increase of $200 million or 22 percent. The increase in revenues for 1998 resulted primarily from an increase in dayrates from an average of approximately $56,000 in 1997 to approximately $70,000 in 1998 and from increased utilization, which improved from an average of 90 percent in 1997 to 91 percent in 1998. Dayrates increased in early 1998 as a result of higher market demand converging with tightening supply. Cost of services for the year ended December 31, 1998 was $675 million compared to $562 million for 1997, an increase of $113 million or 20 percent. The increase in 1998 resulted primarily from rig reactivation 38

39 and mobilization costs and enhanced maintenance costs and employee compensation. A large portion of Sedco Forex's cost of services consists of depreciation and employee-related costs and is fixed or only semi-variable. Accordingly, cost of services does not vary in direct proportion to activity. Cost of services for the year ended December 31, 1998 also includes charges totaling $23 million relating to severance liabilities, the write-down of obsolete fixed assets and contract disputes. Research and engineering expense for the year ended December 31, 1998 was $11 million compared to $10 million for 1997, an increase of $1 million or approximately 10 percent. The increase in 1998 resulted primarily from the higher allocation of central overhead due to Sedco Forex's higher revenues. For 1998, approximately $3 million of research and engineering expense was allocated by Schlumberger to Sedco Forex compared to approximately $2 million in 1997. This allocation is dependent on a number of factors, including the nature and scale of research and engineering projects, the level of central costs and the proportion of Sedco Forex's revenues to Schlumberger's worldwide group revenues. Accordingly, while the allocation methods are considered to be reasonable, the level of research and engineering expenses may not be indicative of ongoing costs for Sedco Forex upon completion of the spin-off from Schlumberger and the merger with Transocean. General and administrative expense for the year ended December 31, 1998 was $26 million compared to $16 million for 1997, an increase of $10 million or 63 percent. The increase in 1998 resulted from the higher allocation of central overhead due to Sedco Forex's higher revenues and from increased marketing and business development efforts. General and administrative expense includes an allocation by Schlumberger to Sedco Forex that amounts to approximately $9 million for 1998 and $4 million for 1997. The general and administrative expense allocation by Schlumberger to Sedco Forex is dependent on a number of factors, including the level of central costs and the proportion of Sedco Forex's revenues to Schlumberger's worldwide group revenues. Accordingly, while the allocation methods are considered to be reasonable, the level of general and administrative expenses may not be indicative of ongoing costs for Sedco Forex upon completion of the spin-off from Schlumberger and the merger with Transocean. Interest expense for the year ended December 31, 1998 was $13 million compared to $20 million for 1997, a decrease of $7 million or 35 percent. The decrease in 1998 resulted primarily from the capitalization of $9 million in interest relating to construction projects. Income tax expense for the year ended December 31, 1998 was $32 million compared to $32 million for 1997. Sedco Forex operates in a number of countries where income tax is charged on a deemed profit basis. Accordingly, income tax expense does not necessarily vary in direct proportion with pre-tax income. The decrease in income tax expense in relation to pre-tax income for 1998 resulted primarily from the release of the remaining valuation allowance relating to U.K. tax loss carryforwards of $15 million. This carryforward, which Sedco Forex believes will be fully utilized, is available to Sedco Forex indefinitely. Net income for the year ended December 31, 1998 was $342 million compared to $261 million for 1997, an increase of $81 million or 31 percent. The increase in 1998 resulted primarily from higher revenues due to increased dayrates and rig utilization, partially offset by charges included in cost of services totaling $20 million. 1997 compared to 1996 Operating revenues for the year ended December 31, 1997 were $891 million compared to $663 million for 1996, an increase of $228 million or 34 percent. The increase in revenues for 1997 resulted primarily from increased dayrates, which improved from an average of approximately $44,000 in 1996 to approximately $56,000 in 1997. Dayrates increased in 1997 as a result of higher market demand converging with tightening supply. Rig utilization increased to 90 percent in 1997 from 88 percent in 1996. Cost of services for the year ended December 31, 1997 was $562 million compared to $476 million for 1996, an increase of $86 million or 18 percent. The increase in 1997 resulted primarily from rig reactivation and mobilization costs and higher maintenance costs and employee compensation. A large portion of Sedco Forex's cost of services consists of depreciation and employee-related costs and is generally fixed or only semi-variable. Accordingly, cost of services generally does not vary in direct proportion to activity. 39

40 Research and engineering expense for the year ended December 31, 1997 was $10 million compared to $10 million for 1996. For each of 1997 and 1998, approximately $2 million of research and engineering expense was allocated by Schlumberger to Sedco Forex. General and administrative expense for the year ended December 31, 1997 was $16 million compared to $14 million for 1996, an increase of $2 million or 14 percent. General and administrative expense includes an allocation by Schlumberger to Sedco Forex that amounts to approximately $4 million for each of 1997 and 1996. Interest expense for the year ended December 31, 1997 was $20 million compared to $8 million for 1996, an increase of $12 million or 150 percent. The increase in 1997 resulted primarily from the financing of the Trident IX and the Trident 16 rigs and borrowings to finance the acquisition of the Actinia and the refinancing of the Sedco 703. Income tax expense for the year ended December 31, 1997 was $32 million compared to $16 million for 1996, an increase of $16 million or 100 percent. Sedco Forex operates in a number of countries where income tax is charged on a deemed profit basis. Accordingly, income tax expense does not necessarily vary in direct proportion with pre-tax income. The increase in 1997 resulted primarily from increased profits that generally were earned in jurisdictions with higher effective tax rates. Net income for the year ended December 31, 1997 was $261 million compared to $148 million for 1996, an increase of $113 million or 76 percent. The increase in 1997 resulted primarily from increased revenues arising from improved dayrates. MARKET OUTLOOK Rig utilization for the third quarter of 1999 averaged approximately 73 percent fleetwide compared to 74.5 percent fleetwide in the second quarter of 1999. The decrease in fleetwide utilization was primarily due to four rigs becoming idle upon the expiration of existing contracts in the second quarter and early in the third quarter, which were not completely offset by three new contracts starting in the third quarter. Average dayrates during the third quarter of 1999 declined to approximately $55,400 from approximately $58,200 in the second quarter of 1999, due primarily to several rigs commencing new lower-rate contracts during the third quarter or being stacked following completion of higher rate contracts. As of September 30, 1999, Sedco Forex had 60% of its fleet days committed for the remainder of 1999 and 27% for the year 2000. Reduced exploration and development activity by Sedco Forex's customers, resulting from the sustained period of low oil prices from late 1997 through early 1999 and industry consolidation over the same time period, continued in the second quarter despite the upturn in prices since February 1999. Rig availability has also increased as a result of expiring contracts and construction by drilling contractors of new rigs that are capable of competing with Sedco Forex's rigs. This decline in exploration and development activity and increased rig availability has created a highly competitive market for contract drilling services, with corresponding reductions in utilization and dayrates for all classes of offshore rigs. Oil prices have rallied from lows experienced in 1998, reaching a price in excess of $24 per barrel in September before falling back to about $22 in October. This level of oil prices suggests that there could be an improving long-term fundamental outlook for the offshore drilling business. Sedco Forex has recently experienced an increase in customer inquiries in all of its principal market areas, but this has not yet led to meaningful increases in dayrates or rig utilization. It is expected that in the near term, customers will continue a cautious approach to exploration and development spending until these commodity price gains prove to be sustainable. Sedco Forex's efforts to secure contracts for its drilling units becoming available due to contract expirations have been and will continue to be adversely affected by continuing market weakness. Some units have been contracted at lower rates in order to secure work and others have been stacked. As of September 30, 1999, eight semisubmersibles, one jackup, four swamp barges, two tenders and one land rig were stacked. However, two idled semisubmersibles will be reactivated under new contracts scheduled to commence in the fourth quarter of 1999. In addition to the loss of revenues associated with stacking rigs and maintaining them 40

41 in idle status, Sedco Forex has incurred and may incur additional expenses associated with severance and related payments to rig operating personnel made redundant as a result. OTHER FACTORS AFFECTING OPERATING RESULTS Sedco Forex's business depends on the level of activity in offshore oil and gas exploration, development and production in markets worldwide. Oil and gas prices, market expectations of potential changes in these prices and a variety of political and economic factors significantly affect this level of activity. Oil and gas prices are extremely volatile and are affected by numerous factors, including - 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 of non-OPEC countries; - the policies of the various governments regarding exploration and development of their oil and gas reserves; - advances in exploration and development technology; and - the political environment of oil-producing regions. The offshore contract drilling industry is highly competitive with numerous industry participants, none of which has a dominant market share. Some of Sedco Forex's competitors may have greater resources than Sedco Forex. 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. Sedco Forex's industry has historically been cyclical. There have been periods of high demand, short rig supply and high dayrates, followed by periods of lower demand, excess rig supply and low dayrates. The industry is currently in a period of low demand, and Sedco Forex is unable to predict when the market will change and if so, to what extent. In addition, rig availability has increased as a result of contract expirations and construction by other drilling contractors of new rigs that are competing with Sedco Forex's rigs. Periods of excess rig supply intensify the competition in the industry and often result in rigs being idled for long periods of time. Sedco Forex's customers may terminate many of Sedco Forex's term drilling contracts if the drilling unit is destroyed or lost or if drilling operations are suspended for a specified period of time as a result of a breakdown of major equipment or, in some cases, due to other events beyond the control of either party. In addition, the drilling contracts for Sedco Forex's newbuild rigs contain termination or term reduction provisions tied to late delivery of these units. In reaction to depressed market conditions, Sedco Forex's customers may also seek renegotiation of firm drilling contracts to reduce their obligations. As of September 30, 1999, Sedco Forex had four new rigs in shipyards under construction. These construction projects are subject to the risks of delay or cost overruns inherent in any large construction project resulting from numerous factors, including the following: - shipyard unavailability; - shortages of equipment, materials or skilled labor; - unscheduled delays in the delivery of ordered materials and equipment; - engineering problems, including those relating to the commissioning of newly designed equipment; - work stoppages; 41

42 - weather interference; - unanticipated cost increases; and - difficulty in obtaining necessary permits or approvals. These factors may contribute to cost variations and delays in the delivery of Sedco Forex's drilling units under construction. Delays in delivery of these units would result in delays in contract commencements, resulting in a loss of revenue to Sedco Forex, and may also cause customers to terminate the drilling contracts for these rigs pursuant to late delivery termination clauses. In the event of termination of a drilling contract for one of these rigs, it is unlikely that Sedco Forex would be able to secure a replacement contract on as favorable terms. Sedco Forex operates in various regions throughout the world that may expose Sedco Forex to political and other uncertainties, including risks of: - war and civil disturbances; - expropriation of equipment; - the inability to repatriate income or capital; and - changing taxation policies. Sedco Forex is protected to a substantial extent against loss of capital assets, but generally not loss of revenue, from most of these risks through insurance, indemnity provisions in its drilling contracts or both. As of September 30, 1999, all areas in which Sedco Forex was operating were covered by existing insurance policies. The offshore drilling business is subject to significant government regulations in different jurisdictions. 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 Sedco Forex's ability to compete. Sedco Forex expects to continue its efforts to structure its operations in order to remain competitive in international markets. Another risk inherent in its operations is the possibility of currency exchange losses where revenues are received and expenses are paid in nonconvertible currencies. Sedco Forex may also incur losses as a result of an inability to collect revenues because of a shortage of convertible currency available to the country of operation. Sedco Forex seeks to limit these risks by structuring contracts such that compensation is made in freely convertible currencies and, to the extent possible, by limiting acceptance of blocked currencies to amounts that match its expense requirements in local currency. Sedco Forex requires highly skilled personnel to operate and provide technical services and support for its drilling units. To the extent demand for drilling services and the size of the worldwide industry fleet increase, shortages of qualified personnel similar to those experienced in 1996-97 could arise, creating upward pressure on wages. Sedco Forex is continuing its recruitment and training programs as required to meet its anticipated personnel needs. On a worldwide basis, Sedco Forex had approximately 13 percent of its employees working under collective bargaining agreements at September 30, 1999. Some of those agreements have expired and negotiations are ongoing for new contracts. Sedco Forex has not experienced any work stoppages as a result of these expirations and negotiations. The general rate of inflation in the majority of the countries in which Sedco Forex operates has been moderate over the past several years and has not had a material impact on Sedco Forex's results of operations. The increase in the demand for offshore drilling rigs experienced in 1996 and 1997 led to higher labor, transportation and other operating expenses as a result of an increased need for qualified personnel and services. Because of the decline in demand for offshore drilling services commencing in 1998, these inflationary pressures have decreased. 42

43 LIQUIDITY AND CAPITAL RESOURCES SOURCES AND USES OF CASH Six months ended June 30, 1999 compared to six months ended June 30, 1998 Cash flows provided by operations for the six months ended June 30, 1999 were $151 million compared to $165 million for the same period in 1998, a decrease of $14 million or approximately 8 percent. The decrease in cash flows provided by operations resulted primarily from reduced net income, partly offset by movements in working capital. Cash flows used in investing activities for the six months ended June 30, 1999 were $250 million compared to $160 million for the same period in 1998, an increase of $90 million or approximately 56 percent. The increase in cash flows used in investing activities resulted primarily from increased capital expenditures on construction projects. Cash flows provided by financing activities for the six months ended June 30, 1999 were $10 million compared to cash flows used in financing activities of $66 million for the same period in 1998, an increase of $76 million. The increase in cash provided by financing activities resulted primarily from proceeds from the issuance of related party debt during the six months ended June 30, 1999. 1998 compared to 1997 Cash flows provided by operations for the year ended December 31, 1998 were $473 million compared to $318 million for 1997, an increase of $155 million or approximately 49 percent. The increase in cash provided by operations resulted primarily from increased net income. Cash flows used in investing activities for the year ended December 31, 1998 were $422 million compared to $19 million for the same period in 1997, an increase of $403 million. The increase in cash used in investing activities resulted primarily from increased capital expenditures on construction projects in 1998 and the receipt of proceeds in 1997 from the sale of two rigs. Cash flows provided by financing activities for the year ended December 31, 1998 were $27 million compared to cash flows used in financing activities of $269 million for the same period in 1997, an increase of $296 million. The increase in cash provided by financing activities resulted primarily from greater proceeds from the issuance of debt during the year ended December 31, 1998 together with the impact of dividends paid in 1997 that were not paid in 1998 and lower repayment of advances from related parties in 1998. CAPITAL EXPENDITURES Sedco Forex's investments in its existing fleet and previously announced fleet additions continue to require significant capital expenditures. Capital expenditures, including capitalized interest, totaled $425 million during the year ended December 31, 1998 and are expected to be approximately $581 million in 1999, including amounts that will be spent on newbuild construction projects as summarized below. In 1999, Sedco Forex has made capital expenditures aggregating $250 million through June 30, and approximately $420 million through September 30. 43

44 The projected total cost, including capitalized interest, and completion dates for Sedco Forex's major rig construction projects are as follows: SEDCO SEDCO CAJUN TRIDENT EXPRESS ENERGY EXPRESS 20 TOTAL ------- ------- ------- ------- ------- (EXPENDITURES IN MILLIONS) Cumulative at December 31, 1998.......... $ 118 $ 107 $ 58 $ 40 $ 323 Actual for six months ended June 30, 1999................................... 60 62 73 23 218 Actual for July 1 to September 30, 1999................................... 41 48 41 21 151 ------- ------- ------- ------- ------- Cumulative at September 30, 1999......... 219 217 172 84 692 Projected for fourth quarter 1999........ 33 39 29 21 122 Projected 2000........................... 46 51 64 27 188 ------- ------- ------- ------- ------- Projected total cost..................... $ 298 $ 307 $ 264 $ 132 $ 1,002 ======= ======= ======= ======= ======= Estimated completion date................ 1Q 2000 1Q 2000 2Q 2000 4Q 2000 These construction projects are subject to the risks of delay or cost overruns inherent in any large construction project resulting from numerous factors, including those listed previously. See "-- Liquidity and Capital Resources -- Capital Expenditures." Sedco Forex intends to fund the cash requirements relating to its capital commitments through available cash balances, borrowings from Schlumberger prior to the spin-off or third parties and other commercial bank or capital market financings. DEBT Sedco Forex's third-party and related party indebtedness are summarized below: Third-party Indebtedness Sedco Forex has entered into financing arrangements with a commercial bank for the Trident IX and Trident 16 pursuant to which $60 million was financed originally in connection with the Trident IX and $60 million was financed originally in connection with the Trident 16. The payments under these financings include an interest component of 7.95% for the Trident IX and 7.20% for the Trident 16, and the remaining terms run through 2003 for the Trident IX and 2005 for the Trident 16. The arrangements provide for a call right on the part of Sedco Forex to repay the financings at a predetermined price, which declines over time, prior to end of the term and to take unencumbered ownership of the rigs. Additionally, under some circumstances, the bank has a put right to cause Sedco Forex to repay the financings at the same price as would apply in the case of a Sedco Forex call. As of June 30, 1999, remaining payments aggregate $42 million under the Trident IX arrangement and $50 million under the Trident 16 arrangement. As of September 30, 1999, remaining payments aggregated $41 million under the Trident IX arrangement and $48 million under the Trident 16 arrangement. Cash to fund the satisfaction of these obligations is expected to be generated from Sedco Forex's operating activities. Related Party Indebtedness At June 30, 1999 Sedco Forex had long-term debt to related parties of $506 million. As of September 30, 1999, this debt totaled $496 million. These loans bear interest at a rate of LIBOR plus 0.5%. These loans have been used to finance both Sedco Forex's existing fleet of rigs and ongoing major construction projects. The loans are repayable in fixed annual amounts over agreement terms ranging from eight to fourteen years, commencing from the date of drawdown or, in the case of the construction projects, on commencement of operating activities by the relevant rig. Sedco Forex has the option to repay the debt in full at any time, subject to an agreed notice period. Cash to fund the repayment of these borrowings is expected to be generated from Sedco Forex's operating activities. Sedco Forex is required to repay the portion of this indebtedness that remains following the spin-off, which is estimated to be approximately $350 million upon completion of the 44

45 spin-off. See "Summary -- The Companies -- Transocean Offshore Inc. -- Recent Developments" and "The Transaction Agreements -- The Distribution Agreement -- Intercompany Indebtedness and Other Financing Matters." DERIVATIVE INSTRUMENTS Occasionally, Sedco Forex uses derivative instruments such as forward currency contracts and foreign currency options. Forward currency contracts provide a hedge against currency fluctuations on assets/ liabilities denominated in other than a functional currency. Options are usually entered into to hedge against currency variations on firm commitments generally involving the construction of drilling rigs. Sedco Forex defers gains and losses on these currency contracts, which qualify as accounting hedges, and recognizes them when the underlying foreign exchange exposure is realized. See "-- Quantitative and Qualitative Disclosures About Market Risk." ASSET DIVESTITURES In September 1997, Sedco Forex sold two of its rigs, the Sedco Explorer and the Drill Star, to Sea Wolf Drilling Limited, an entity in which Schlumberger has an indirect 25% interest and which is 75% owned by a third-party investment company. The rigs are being operated by Sedco Forex under bareboat charters. The proceeds from these asset divestitures were used to fund capital expenditures. See "Business of Sedco Forex -- Drilling Rig Status." SOURCES OF LIQUIDITY Sedco Forex believes that its cash and cash equivalents, cash generated from operations, borrowing capacity and access to other financing sources will be adequate to meet its anticipated short-term and long-term liquidity requirements, including scheduled debt repayments and capital expenditures for new rig construction and upgrade projects. 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, Sedco Forex does not anticipate that the adoption of the new statement will have a significant effect on the results of operations or the financial position of the company. Sedco Forex will adopt SFAS 133 as of January 1, 2001. YEAR 2000 ISSUES OVERVIEW The "year 2000 issue" is the inability of computers and computing technology to correctly process the year 2000 date change. Sedco Forex recognizes that the year 2000 issue creates a significant uncertainty to its business, and has a proactive, year 2000 readiness program. As part of its program, most nonready systems are being replaced or upgraded with new systems that will provide certain competitive benefits, as well as ensure year 2000 readiness to minimize customer and shareholder business disruptions caused by this issue. Schlumberger formed a company-wide task force in late 1997 to provide guidance to its business units, including Sedco Forex, and monitor progress of the program. Sedco Forex has dedicated internal resources and has consulted with and engaged various third parties, including outside consultants and service providers, to assist it in its year 2000 efforts. 45

46 Overall, the program is proceeding on schedule. In 1994, Schlumberger decided to upgrade its main internal business systems, including those of Sedco Forex, with year 2000 ready programs. This is expected to be completed by the end of 1999. Those aspects of Schlumberger's internal business systems that are not scheduled to be covered by this upgrade effort are being separately addressed through an upgrade of existing legacy systems to year 2000 ready status. PROGRAM Sedco Forex's year 2000 program uses a business risk assessment and prioritization approach, and is intended to produce year 2000 ready products and services and to minimize disruptions in business operations. The program is divided into three major readiness categories: - assets - information technology ("IT") - commercial Within each category, there are two program stages: - Stage I: assessment and preparation -- this stage focuses on up-front planning, data gathering and correction planning. This includes -- raising year 2000 awareness; -- carrying out a detailed asset inventory; -- assessing the scope of the year 2000 problem; -- determining appropriate corrections, testing/validation, acceptance and deployment approaches; and -- preparing project plans and budgets. - Stage II: repairs, testing, and deployment -- this stage focuses on "fixing" year 2000 problems and testing those fixes, followed by user-acceptance, redeployment and operational validation of the repaired, replaced or otherwise fixed systems. Assets. This category consists of (1) equipment that Sedco Forex uses to provide services to its customers and (2) hardware and software associated with embedded computer chips that are used in the operation of Sedco Forex's rigs. Program progress under this category is on schedule with the majority of Stage I activities completed; Sedco Forex is now finalizing Stage II activities. Sedco Forex expects activities associated with year 2000 readiness of assets to be completed by December 1999. Information Technology. This category deals with traditional IT infrastructure, such as business applications, computer hardware/software, IT networks and communication equipment. Implementation of the business applications software system has been completed. The activities associated with other systems in this IT category, such as computer hardware/software, IT networks and communications equipment, also are on schedule. Stage I activities have been completed and Stage II activities are being finalized and are expected to be completed by November 1999. Commercial. This category deals with Sedco Forex's efforts to avoid being adversely affected by year 2000 issues from external entities, suppliers, financial institutions and service providers not affiliated with Sedco Forex. Stage I of the program includes a process for mitigating the year 2000 issues associated with key suppliers. Sedco Forex is communicating with its key suppliers, business partners and customers seeking their assurances that they will be year 2000 ready. Based on responses, Sedco Forex has developed contingency plans for those areas that pose significant risk from the year 2000 issue; however, Sedco Forex could potentially experience disruptions to some aspects of its operations from non-compliant systems utilized by unrelated third-party entities. Work in this category is on schedule. The Stage I activities have been 46

47 completed and Stage II efforts are being finalized. Sedco Forex expects these efforts to be completed by November 1999. CONTINGENCY PLANNING Sedco Forex is reviewing the activities associated with each category and is determining those activities at risk of not being completed in time to prevent a year 2000 disruption. Appropriate contingency plans are being designed for each of the "at risk" activities to provide an alternative means of functioning that minimizes the effect of the potential year 2000 disruption, both internally and on Sedco Forex's customers. These contingency-planning activities are expected to be completed in November 1999. COSTS Year 2000 program funding requirements have been incorporated into Sedco Forex's capital and operating plans and are not expected to have a material adverse impact on its financial condition or results of operations. Sedco Forex estimates the cost of its year 2000 program to be around $3 million, of which approximately $2 million has been spent to date. The estimated breakdown of these costs is 53% for employee resources, 18% for IT-related upgrades and repair and 29% for non-IT embedded chip technology. In addition, through cost allocations from Schlumberger, Sedco Forex has contributed to the year 2000 work performed on common legacy systems. These allocations amounted to less than $1 million. The above costs do not include the normal upgrading of business and financial systems that would be year 2000 ready, or rationalization costs of year 2000 ready technology already defined by Sedco Forex's business plans. RISKS Dates and schedules for Sedco Forex's year 2000 program are based on management's best estimates, which involve numerous assumptions, including: - the results of Stage I assessments; - the continued availability of certain resources; - third-parties' year 2000 status and plans; and - other factors. There can be no guarantee that these estimates will be achieved, or that there will not be delays in, or increased costs associated with, implementation of the year 2000 program. Specific factors that might cause differences between present estimates and actual results include: - the availability and cost of skilled personnel; - consultants, and independent contractors; - the ability to locate and correct all relevant computer code; - timely and effective action by third parties and suppliers; - the ability to implement interfaces between year 2000 ready systems and those systems not being replaced; and - similar uncertainties. Because of the general uncertainty inherent in the year 2000 issues, which is partially attributable to the interconnection of global businesses, Sedco Forex cannot assure that it will be able to resolve appropriately all year 2000 issues that may affect its operations and business or expose it to third-party liability. The failure to correct a year 2000 problem could result in an interruption in, or a failure of, all or part of normal business activities or operations. Such failures could materially and adversely affect Sedco Forex's financial condition and results of operations. Because of the uncertainties described above, Sedco Forex presently is unable to 47

48 determine whether the consequences of such year 2000 failures will have a material impact on its financial condition or results of operations. EURO DISCLOSURES On January 1, 1999, the euro became the official single currency of the European Union. As of that date, the conversion rates of the national currencies of the eleven member states adopting the euro were fixed irrevocably. The national currencies will initially remain in circulation as nondecimal subunits of the euro and will be replaced by euro bills and coins by July 2002. During the transition period from January 1999 to January 2002, public and private parties may pay for goods and services using either the euro or the national currency on a "no compulsion, no prohibition" basis. Sedco Forex operates for the most part in a U.S. dollar-denominated environment and does not expect the introduction of the euro to have a material adverse effect on its business, financial position or results of operations. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Interest Rate Risk. Exposure to market risk for changes in interest rates relates primarily to Sedco Forex's long-term debt obligations. Because these obligations consist solely of fixed rate indebtedness or related party variable rate indebtedness that is required to be repaid following the spin-off, Sedco Forex does not believe its exposure to interest rate market risk is material. Foreign Exchange Risk. Sedco Forex operates internationally, resulting in exposure to foreign exchange risk. Sedco Forex uses a variety of techniques to minimize the exposure to foreign exchange risk, including customer contract terms and the use of foreign exchange derivative instruments or spot purchases. Sedco Forex does not enter into derivative transactions for speculative purposes. At December 31, 1998, Sedco Forex had no material open foreign exchange contracts and had foreign currency options totalling $68 million. * * * 48

49 BUSINESS OF TRANSOCEAN Transocean is a leading international provider of offshore contract drilling services for oil and gas exploration, development and production. Transocean owns, has partial ownership interests in or operates 30 mobile offshore drilling units. Transocean's fleet consists of seven fourth-generation semisubmersibles, thirteen second- and third-generation semisubmersibles, four drillships, including two newbuild drillships, the Discoverer Enterprise, which is currently in the final stages of commissioning and testing, and the Discoverer Spirit, which is en route to a U.S. Gulf Coast shipyard for outfitting with drilling equipment, and six jackup rigs. Transocean also has under construction one additional Discoverer Enterprise-class drillship, to be named Discoverer Deep Seas. Transocean contracts these drilling rigs, related equipment and work crews primarily on a dayrate basis to drill offshore wells. Transocean also provides additional services, including turnkey drilling, coiled tubing drilling and well intervention and management of third-party well service activities. Transocean was founded in 1953 by predecessors of Sonat Inc. and J. Ray McDermott & Co., Inc. to design and construct the first jackup rig in the Gulf of Mexico. Transocean, then known as "The Offshore Company," began international drilling operations in the late 1950s and was one of the first contractors to offer drilling services in the North Sea. Transocean was publicly traded from 1967 until 1978, when it became a wholly owned subsidiary of Sonat Inc. In June 1993, Transocean, then known as "Sonat Offshore Drilling Inc.," completed an initial public offering of approximately 60 percent of the outstanding shares of its common stock. In July 1995, Sonat Inc. sold its remaining 40 percent interest in Transocean through a secondary public offering and currently owns no Transocean share capital. In September 1996, Transocean acquired substantially all of the outstanding capital shares of Transocean ASA, a Norwegian offshore drilling company, for an aggregate purchase price of approximately $1.5 billion in common stock and cash, including direct transaction costs and costs of purchasing minority shares completed in 1997, and changed its name to "Transocean Offshore Inc." On May 14, 1999, Transocean completed a corporate reorganization pursuant to which it reorganized from a Delaware corporation into a Cayman Islands corporation. Transocean Offshore Inc. is a Cayman Islands corporation with offices located at 4 Greenway Plaza, Houston, Texas 77046. Its telephone number at that address is (713) 232-7500. For a more detailed description of the business of Transocean, see the description set forth in Transocean's 1998 Annual Report on Form 10-K, which is incorporated by reference herein. See "Where You Can Find More Information." Further information about Transocean's drilling rigs, including rigs under construction, as of September 30, 1999 is set forth below.

See "Interests Of Certain Persons -- Transocean Sedco Forex Chairman's Consulting Agreement." The board of directors of Transocean Sedco Forex will be divided into three staggered classes. Messrs.

The chairmen of any other committees will be designated as equally as practicable by Transocean's and Schlumberger's respective board designees. Under the merger agreement, Transocean and Schlumberger agreed to use all reasonable efforts to maintain the proportional allocation between Transocean and Schlumberger designees to the board and its committees for a period of three years after the completion of the merger. Transocean and Schlumberger also agreed that if a director dies, resigns or is removed from the board prior to the expiration of the three-year period following the merger, the remaining Transocean designees, if the director was a director designated by Transocean, or Schlumberger designees, if the director was a director designated by Schlumberger, on the board will nominate a replacement for action by the full board. * * * 54

55 TRANSOCEAN SEDCO FOREX CHAIRMAN'S CONSULTING AGREEMENT As part of the merger and as a condition to his appointment as chairman of the Transocean board, Victor E. Grijalva, Vice Chairman of Schlumberger, will enter into a consulting agreement with Transocean Sedco Forex. The consulting agreement will contain the following material terms: - Transocean Sedco Forex will nominate Mr. Grijalva to its board of directors to serve as Chairman until his 65th birthday, at which time he will resign such position; - until the time of his resignation, Mr. Grijalva will provide consulting services to Transocean Sedco Forex, as an independent contractor, with regard to long-range planning, strategic direction and integration and rationalization matters; - Transocean Sedco Forex will pay Mr. Grijalva $400,000 per year; - Transocean Sedco Forex will indemnify Mr. Grijalva in connection with the services he provides to the fullest extent available under Transocean Sedco Forex's articles of association; and - Mr. Grijalva will be entitled to the non-cash compensation and benefits Transocean Sedco Forex provides to non-employee directors. EMPLOYMENT AGREEMENTS Under each of the agreements described below, a change of control will be deemed to have occurred upon completion of the spin-off and the merger. Transocean has entered into employment agreements with its executive officers, including J. Michael Talbert, W. Dennis Heagney, Robert L. Long, Jon C. Cole, Donald R. Ray, Eric B. Brown, Barbara S. Koucouthakis and Alan A. Boussard. The occurrence of a change in control under these agreements triggers provisions that generally guarantee a minimum salary and bonus for a period of three years following the change of control. In consideration of cash payments or, in some cases, elimination of some restrictions on vesting of certain restricted stock grants, each of these executive officers has agreed to waive the guarantee of a minimum bonus. The employment agreements also provide generally that, in the event that the executive officer's employment with Transocean is terminated within three years of a change of control (1) for reasons other than death, disability or for "cause," (2) by the executive officer for good reason, which includes a diminution of responsibilities or compensation or (3) by a voluntary determination of the executive officer to leave during the 30-day period immediately following the first anniversary of the change of control, the executive would receive the following: - any unpaid portion of his then-annual base salary and prorated portion of his highest bonus paid either in the last three years before the change of control or for the last completed fiscal year after the change of control (the "highest bonus"); - a lump-sum payment equal to three times the sum of his highest bonus and his annual base salary, based on the highest monthly salary paid in the twelve months prior to the change of control; - health and welfare benefits to him and his family for a three-year period at least equal to those that would have been provided had his employment not been terminated; and - a lump sum amount equal to the excess of (1) the actuarial equivalent of the benefit under Transocean's Retirement Plan and Supplemental Retirement Plan had the executive's employment continued for three years after termination over (2) the actuarial equivalent of the executive's actual benefit under those plans. Neither Transocean nor Schlumberger has determined whether any of the above named executives subject to employment agreements will be terminated following the effective time of the merger. Assuming that all such executives are terminated in a qualifying termination of employment, Transocean Sedco Forex would be required to pay the executive officers aggregate payments currently estimated to be approximately $15 million. In addition, the employment agreements provide that Transocean is obligated to pay an additional amount sufficient to make the executive officer whole with respect to any excise tax that may be imposed by Section 4999 of the U.S. Internal Revenue Code and any taxes imposed on such additional amounts. Because the merger will constitute a change of control under the employment agreements, each of the above-named executives will have the right to leave Transocean Sedco Forex voluntarily for any reason at any time during the 30-day period beginning on the first anniversary of the merger, and in so leaving will receive the benefits described above. * * * 55

62 SEDCO FOREX HOLDINGS LIMITED NOTES TO COMBINED FINANCIAL STATEMENTS (AMOUNTS IN THOUSANDS, UNLESS OTHERWISE INDICATED) 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, its subsidiaries and Schlumberger, in accordance with a distribution agreement described below (collectively referred to as "Sedco Forex"). Although Sedco Forex is 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 bases 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, have been 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 11). 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 was historically not operated 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 stockholders' 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, will be retained by Schlumberger in accordance with the distribution agreement described below. In addition, certain financial matters have been agreed to which limit debt and require a minimum cash level at the time of the audited pre-closing financial statements to be delivered prior to the distribution. Sedco Forex provides offshore drilling services with semisubmersibles, jackup rigs, dynamically positioned drillships and drilling tenders to customers throughout the world. Distribution to Shareholders and Merger with Transocean Offshore Inc. On 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 provides for a series of combination transactions which will include: the transfer of certain assets and liabilities between Sedco Forex and Schlumberger and the distribution of Sedco Forex stock to Schlumberger shareholders. After the distribution, Sedco Forex will merge with a wholly-owned subsidiary of Transocean and Schlumberger shareholders will receive shares of Transocean in exchange for their shares of Sedco Forex. Following the distribution and merger, Schlumberger shareholders will own approximately 52 percent of the diluted ordinary shares of the combined company that F-7

63 SEDCO FOREX HOLDINGS LIMITED NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED) (AMOUNTS IN THOUSANDS, UNLESS OTHERWISE INDICATED) will be renamed Transocean Sedco Forex. These transactions are expected to be completed by December 31, 1999. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The Combined Financial Statements of Sedco Forex have been prepared in accordance with accounting principles generally accepted in the United States. Principles of Combination All significant intercompany accounts and transactions are eliminated. The equity method of accounting is used for investments in affiliates in which Sedco Forex owns between 20% and 50%. Interim Financial Information The financial information as of June 30, 1999 and for the six months ended June 30, 1999 and 1998 is unaudited but includes all adjustments, consisting only of normal and recurring adjustments, that management considers necessary for a fair presentation of its financial position, operating results and cash flows. Results for the six months ended June 30, 1999 are not necessarily indicative of results to be expected for the full year 1999 or for any future period. Revenue Recognition Operating revenues are recognized as earned, based on contractual daily rates. In connection with drilling contracts, Sedco Forex may receive lump sum fees for the mobilization of equipment and personnel or for capital improvements to rigs. In connection with contracted mobilizations, to the extent that expenses exceed fees received, the net costs are deferred and amortized over the appropriate periods of benefit, generally the term of the contract. If losses are anticipated on the contract, net mobilization costs are expensed immediately. Profits are recognized based on contractual daily rates. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. While actual results could differ from these estimates, management believes that the estimates are reasonable. Translation of Non-US Currencies Sedco Forex uses the US dollar as its functional currency. All realized and unrealized transaction gains and losses are included in income in the period in which they occur. Transaction gains (losses) included in results of operations were $1.0 million, $5.0 million, and $(274) in 1998, 1997 and 1996, respectively. Investments Short-term investments are stated at cost plus accrued interest, which approximates market, and are comprised primarily of Eurodollar time deposits, certificates of deposit and commercial paper, Canadian treasury bills, Euronotes and Eurobonds, substantially all denominated in US dollars. These investments have F-8

64 SEDCO FOREX HOLDINGS LIMITED NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED) (AMOUNTS IN THOUSANDS, UNLESS OTHERWISE INDICATED) original maturity dates not exceeding three months, and are considered cash equivalents for purposes of reporting cash flows. Fair Value of Financial Instruments The fair value of cash, accounts receivable, trade accounts payable, short-term borrowings, long-term debt and accrued expenses are not materially different than their carrying amounts as reported at December 31, 1998 and 1997. Concentration of Credit Risk Financial instruments which potentially subject Sedco Forex to concentration of risk consist primarily of accounts receivable. Sedco Forex maintains an allowance for uncollectible accounts receivable based upon expected collectibility. Sedco Forex performs ongoing credit evaluations of its customers' financial condition. For the years ended December 31, 1998, 1997 and 1996, one customer accounted for approximately 19.2%, 24.1%, and 25.6%, respectively, of Sedco Forex's total revenue. Total accounts receivable from this customer were $44 million and $46 million at December 31, 1998 and 1997, respectively. Materials and Supplies Inventories are stated principally at average cost less an allowance for obsolescence. Fixed Assets and Depreciation Fixed assets are stated at cost less accumulated depreciation, which is provided for by charges to income over the estimated useful lives of the assets by the straight-line method. Expenditures for renewals, replacements, and improvements are capitalized. Maintenance and repairs are charged to operating expenses as incurred. Upon sale or other disposition, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposal, is charged or credited to income. Estimated useful lives of rigs range from 10 to 25 years, buildings and improvements from 10 to 30 years and machinery and equipment from 4 to 12 years. From time to time, major improvements are performed on the rigs which extend their useful lives. These improvements are amortized over 10 to 15 years. Capitalized Interest Sedco Forex capitalizes interest expense during the new construction or upgrade of qualifying assets. Interest expense capitalized was $8.7 million for the year ended 1998 and $11.7 million (unaudited) for the six months ended June 30, 1999. Sedco Forex did not capitalize any interest during 1997 or 1996. Impairment of Long-Lived Assets Sedco Forex reviews the appropriateness of the carrying value of its long-lived assets whenever events or changes in circumstances indicate that the historical cost carrying value of an asset may no longer be appropriate. Sedco Forex assesses recoverability of the carrying value of the asset by estimating the future net cash flows expected to result from the asset, including eventual disposition. If the future net cash flows are less than the carrying value of the asset, an impairment loss is recorded equal to the difference between the asset's carrying value and fair value. F-9

65 SEDCO FOREX HOLDINGS LIMITED NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED) (AMOUNTS IN THOUSANDS, UNLESS OTHERWISE INDICATED) Research and Engineering All research and engineering expenditures are expensed as incurred, including costs relating to patents or rights that may result from such expenditures. Research and engineering is performed on a centralized basis and the expense is allocated from Schlumberger to Sedco Forex. Taxes on Income Sedco Forex's operating results historically have been included in Schlumberger's consolidated US and state income tax returns and in tax returns of Schlumberger's foreign subsidiaries. The provision for income taxes in Sedco Forex's combined financial statements has been determined on a separate return basis. Taxes on income are computed in accordance with the tax rules and regulations of the taxing authorities where the income is earned. The income tax rates imposed by these taxing authorities vary substantially. Taxable income may differ from pre-tax income for financial accounting purposes. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax asset will not be realized. Comprehensive Income Sedco Forex has no material components of other comprehensive income and accordingly comprehensive income is the same as net income for all periods presented. Derivative Financial Instruments Occasionally, Sedco Forex uses derivative instruments such as forward currency contracts and foreign currency options. Forward currency contracts provide a hedge against currency fluctuations on assets/ liabilities denominated in other than a functional currency. Options are usually entered into to hedge against currency variations on firm commitments generally involving the construction of drilling rigs. Sedco Forex defers gains and losses on these currency contracts which qualify as accounting hedges and recognizes them when the underlying foreign exchange exposure is realized. As of December 31, 1998, options were outstanding for the US dollar equivalent of $68 million in various foreign currencies. New Accounting Standards In 1998, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) 133, "Accounting for Derivative Instruments and Hedging Activities," which requires that Sedco Forex recognize all derivative instruments as either assets or liabilities in the statement of financial position and measure those instruments at fair value. The standard is effective for Sedco Forex for fiscal years beginning after June 15, 2000. Sedco Forex does not anticipate that the implementation of the new standard in the first quarter of 2001 will have a material effect on the combined financial position and results of operations. 3. 1998 CHARGE During 1998, Sedco Forex recorded a charge of $20.4 million after tax, which included charges of $3.6 million for severance and termination costs, $9.8 million for asset impairments and a $7 million provision for a potential legal claim. The severance and termination costs and asset impairment charges resulted from the slowdown in business. The charge has been classified in cost of services. As of June 30, 1999, all of the severance and termination costs had been incurred. F-10

The financing arrangements provide for a call right on the part of Sedco Forex to repay the financings prior to expiration of their scheduled terms, and in some circumstances a put right on the part of the banks to call Sedco Forex to repay the financings. Under either circumstance, Sedco Forex would retain ownership of the rigs.

PENSION AND OTHER BENEFIT PLANS Schlumberger sponsors several defined benefit pension plans that cover substantially all US employees. The benefits are based on years of service and compensation on a career-average pay basis. These plans are substantially fully funded with a trustee in respect to past and current service. Charges to expense are based upon costs computed by independent actuaries. The funding policy is to contribute annually amounts that are F-12

68 SEDCO FOREX HOLDINGS LIMITED NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED) (AMOUNTS IN THOUSANDS, UNLESS OTHERWISE INDICATED) allowable for federal income tax purposes. These contributions are intended to provide for benefits earned to date and those expected to be earned in the future. The assumed discount rate, rate of compensation increases and return on plan assets used to determine pension expense in 1998 were 7.5%, 4.5% and 9%, respectively. In 1997, the assumptions were 8%, 4.5% and 8.5%, respectively. In 1996, the assumptions were 7.5%, 4.5% and 8.5%, respectively. Net pension cost in the US for 1998, 1997 and 1996, included the following components: 1998 1997 1996 ----- ----- ----- Service cost -- benefits earned during the period........... $ 396 $ 243 $ 171 Interest cost on projected benefit obligation............... 460 416 370 Expected return on plan assets (actual return: 1998 -- $1,049; 1997 -- $1,108; 1996 -- $623).............

For defined benefit plans, charges to expense are based upon costs computed by independent actuaries. These plans are substantially fully funded with trustees in respect to past and current service. For defined contribution plans, funding and cost are generally based upon a predetermined percentage of employee compensation. Expenses for both defined F-13

69 SEDCO FOREX HOLDINGS LIMITED NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED) (AMOUNTS IN THOUSANDS, UNLESS OTHERWISE INDICATED) benefit plans and defined contribution plans were immaterial to Sedco Forex for each of the three years ended December 31, 1998. Other Deferred Benefits In addition to providing pension benefits, Sedco Forex has other deferred benefit programs. Expenses for these programs were $9.2 million, $9.1 million and $8.2 million for 1998, 1997 and 1996, respectively. Health Care Benefits Sedco Forex provides health care benefits for certain active employees. The cost of providing these benefits is recognized as an expense when incurred and aggregated $721, $668 and $471 in 1998, 1997 and 1996 respectively. Outside the US, such benefits are mostly provided through government-sponsored programs. Postretirement Benefits Other Than Pensions Sedco Forex provides certain health care benefits to former employees who have retired under the US pension plans. The principal actuarial assumptions used to measure costs were a discount rate of 7.5% in 1998 and 8% in 1997 and 1996. The overall medical cost trend rate assumption beginning December 31, 1996 was 9% graded \to 5% thereafter. Previously, the overall assumption had been 10% graded to 6% over the next six years and thereafter. Net periodic postretirement benefit cost in the US for 1998, 1997 and 1996 included the following components: 1998 1997 1996 ---- ---- ---- Service cost-benefits earned during the period.............. $136 $ 80 $ 58 Interest cost on accumulated postretirement benefit obligation................................................ 295 291 328 Amortization of unrecognized net gain and other.............

If the assumed medical cost trend rate was increased by one percentage point, health care cost in 1998 would have been $0.5 million, and the accumulated postretirement benefit obligation would have been $5.2 million at December 31, 1998. If the assumed medical cost trend rate was decreased by one percentage point, health care cost in 1998 would have been $0.4 million, and the accumulated postretirement benefit obligation would have been $4.0 million at December 31, 1998. 8. LEASES AND LEASE COMMITMENTS Minimum rental commitments under noncancellable operating leases, primarily real estate and office facilities and bareboat charters, in effect at December 31, 1998 are as follows: YEAR ENDED DECEMBER 31, ----------------------- 1999........................................................ $34,162 2000........................................................ 25,438 2001........................................................ 319 2002........................................................ 52 2003........................................................ 46 Thereafter.................................................. 496 Operating lease rental expense aggregated $56 million, $30 million and $16 million for 1998, 1997 and 1996, respectively. Included in the rental expense and future minimum rental commitments above are office space rentals and the semisubmersible rigs Drillstar and Sedco Explorer. These rigs are being operated by Sedco Forex under bareboat charters with an entity in which Sedco Forex has a 25% equity interest. 9. SEGMENT AND GEOGRAPHIC AREA INFORMATION Sedco Forex operates in one industry segment, offshore contract drilling services. For the years ended December 31, 1998, 1997 and 1996, one customer accounted for approximately 19.2%, 24.1%, and 25.6%, respectively, of Sedco Forex's total revenue. Sedco Forex did not have revenue from third-party customers in its country of domicile during the last three years. Only Nigeria, Indonesia and the United Kingdom represent countries for which revenues and long-lived assets exceeded 10% of the totals for the three years ended F-15

STOCK OPTION PLANS Schlumberger applies Accounting Principles Board Opinion (APB) 25 and related Interpretations in accounting for its stock option plans. Accordingly, no compensation cost has been recognized for its stock option plans. Had compensation cost for the Schlumberger plans been determined based on the fair value at the grant dates for awards under these plans, consistent with the methodology of SFAS 123, Sedco Forex's net income would have been the pro forma amounts indicated below: 1998 1997 1996 -------- -------- -------- Net income As reported........................................ $341,578 $260,455 $147,535 Pro forma.......................................... 339,537 259,244 146,817 As required by SFAS 123, the above pro forma data reflect the effect of stock option grants during 1998, 1997, and 1996. During 1998, 1997, 1996 and in prior years, key employees of Sedco Forex were granted stock options under the Schlumberger stock option plans. For all of the stock options granted, the exercise price of each option equals the market price of Schlumberger stock on the date of grant; an option's maximum term is ten years, and options generally vest in 20% increments over five years. As required by SFAS 123, the fair value of each grant is estimated on the date of grant using the multiple option Black-Scholes option-pricing model with the following weighted-average assumptions used for 1998, 1997 and 1996: dividend of $0.75; expected volatility of 21%-25% for 1998 grants, 21% for 1997 grants and 20% for 1996 grants; risk-free interest rates of 4.35%-5.62% for the 1998 grants, 5.80%-6.77% for the 1997 grants and 5.09%-6.01% for the 1996 grants; and expected option lives of 5.02 years for the 1998 grants, 5.09 years for the 1997 grants and 5.39 years for the 1996 grants.

RELATED PARTY TRANSACTIONS In certain countries, Sedco Forex participates in Schlumberger's centralized treasury and cash processes. In these countries, cash is managed either through zero balance accounts or an interest-bearing offsetting mechanism. Cash disbursements for operations, acquisitions and other investments are 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 have been 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 include relative sales, headcount, square footage, transaction processing costs, adjusted operating expenses and others. These allocations resulted in charges of $88 million, $49 million and $37 million being recorded in Sedco Forex's F-17

These loans bear interest at rates based on fifty basis points over the LIBOR. These loans have been used to finance both Sedco Forex's existing fleet of rigs and ongoing major construction projects. The loans are repayable in fixed annual amounts over agreement terms ranging from eight to fourteen years, commencing from the date of drawdown or, in the case of the construction projects, on commencement of operating activities by the relevant rig. Sedco Forex has the option to repay the debt in full at any time, subject to an agreed notice period. Interest expense on these loans aggregated $11 million, $10 million and $4 million for 1998, 1997 and 1996, respectively. The related party receivables and payables balances included in the combined balance sheets represent amounts arising from intercompany transactions entered into by Sedco Forex, to settle outstanding customer and trade receivables and payables with other Schlumberger entities. There are no formal tax sharing arrangements between Sedco Forex and any entity of Schlumberger. In certain countries, Sedco Forex is a division of the Schlumberger legal entity that is the ultimate tax payer in that jurisdiction. 12. INVESTMENTS IN ASSOCIATED COMPANIES Sedco Forex has a 25% interest in Sea Wolf Drilling Limited. In September 1997, Sedco Forex sold two semisubmersible rigs, Drillstar and Sedco Explorer, to Sea Wolf Drilling Limited. The rigs are being operated by Sedco Forex under bareboat charters. The sale resulted in a deferred gain of $157 million which is being amortized to cost of services over the 6 year life of the bareboat charter. Sedco Forex also has a 50% interest in Overseas Drilling Limited ("ODL") which owns the drillship Joides Resolution. The drill-ship is contracted to perform drilling and coring operations in deep waters worldwide for the purposes of scientific research. Sedco Forex manages and operates the vessel on behalf of ODL. 13. COMMITMENTS AND CONTINGENCIES A claim for approximately $85 million has been filed against Sedco Forex for an alleged late return of a chartered rig and for breach of maintenance obligations under the charter. In addition, a claim has been filed against Sedco Forex for certain management contracts entered into by Sedco Forex in connection with two rigs operated by Sedco Forex. The claim alleges breach of contract, negligence and fraud and seeks damages of approximately $51 million. Sedco Forex is also party to various other legal proceedings and claims which arise in the ordinary course of business and for certain of these proceedings has been indemnified by Schlumberger. As of December 31, 1998 there are no such matters pending that Sedco Forex expects to be material in relation to its business, financial condition, results of operations or cash flows. F-18

SUBSEQUENT EVENT An after-tax charge of $32.5 million was recorded in March 1999. This charge consisted primarily of severance costs of $13.2 million (600 employees) and provisions for potential legal claims of $19.3 million. During March 1999, Sedco Forex obtained two additional loans aggregating $158 million from a related party. These loans are being used to finance Sedco Forex's existing fleet of rigs. Both loans bear interest at rates based on a fixed spread over the LIBOR. Both loans have a repayment term of ten years. 16. INCOME PER COMMON SHARE (UNAUDITED) Income per common share is calculated in accordance with FASB Statement No. 128, Earnings per Share ("SFAS 128"). Basic income per common share is computed by dividing the net income applicable to common shares by the weighted average common shares outstanding during the period. Diluted earnings per common share would adjust basic income per common share for the effects of any convertible securities, stock options and other potentially dilutive financial instruments, only in the periods in which such effort is dilutive. The pro forma income per common share was calculated based on net income of Sedco Forex using the number of shares expected to be issued to the shareholders of Sedco Forex upon the consummation of the merger (Note 1). The pro forma average common shares outstanding were calculated based on approximately 100.8 million diluted Transocean Offshore Inc. ordinary shares issued on the date the merger was announced. Upon consummation of the merger Schlumberger shareholders will own approximately 52% of the diluted Transocean Sedco Forex ordinary shares and the existing holders of Transocean ordinary shares will own the remaining 48%. Accordingly, the shareholders of Schlumberger will own approximately 109.2 million diluted Transocean Sedco Forex ordinary shares. Historical earnings per share has not been presented because Sedco Forex did not have a capital structure as of December 31, 1998. F-19
