PROPOSED TRANSACTIONS—YOUR VOTE IS VERY IMPORTANT

        The boards of directors of Transocean Inc. and GlobalSantaFe Corporation have approved a merger that will combine Transocean and GlobalSantaFe. The board of directors of Transocean has also approved a reclassification of the Transocean ordinary shares in connection with the merger. We believe that the merger will expand and enhance both companies' mobile offshore drilling unit fleets, thus better positioning the combined company to address the growing and more technologically challenging needs of their customers on a global basis. We believe that the merger will benefit the shareholders of both companies, and we ask for your support in voting for the proposals at our respective meetings.

        When the reclassification of Transocean ordinary shares and the merger are completed, Transocean's shareholders will receive 0.6996 Transocean ordinary shares and $33.03 in cash in exchange for each Transocean ordinary share they currently own. Shareholders of GlobalSantaFe will receive 0.4757 Transocean ordinary shares (after giving effect to the reclassification) and $22.46 in cash in exchange for each GlobalSantaFe ordinary share they currently own. We expect that approximately 318 million of Transocean's ordinary shares will be outstanding after the reclassification and the merger, with the shareholders of Transocean and GlobalSantaFe immediately prior to the transactions holding approximately 66% and 34% of those shares, respectively.

        The transactions cannot be completed without the approval of Transocean's shareholders of the reclassification, the issuance of Transocean ordinary shares in the merger, the amendment and restatement of Transocean's memorandum and articles of association, the approval of GlobalSantaFe's shareholders of the merger and the approval of the Cayman Islands court. We have scheduled separate meetings to be held on            , 2007 for our respective shareholders to vote on the matters requiring shareholder approval.

        The Transocean and GlobalSantaFe boards of directors each recommend that their respective shareholders vote "FOR" the proposals.

        The dates, times and places of these meetings are contained in the attached notices.

        This joint proxy statement provides you with detailed information about the reclassification, the merger, the shareholder meetings and the hearing of the application for approval by the Cayman Islands court. You can also obtain financial and other information about Transocean and GlobalSantaFe from documents filed with the Securities and Exchange Commission. We encourage you to carefully read the joint proxy statement and the documents incorporated by reference.

        See "Risk Factors" beginning on page 20 for a discussion of risks that should be considered by Transocean's and GlobalSantaFe's shareholders before voting at their respective meetings.

        Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved the Transocean ordinary shares to be issued in the merger or determined if this joint proxy statement is accurate or adequate. Any representation to the contrary is a criminal offense.

        This joint proxy statement is dated            , 2007 and is first being mailed to shareholders of Transocean and GlobalSantaFe on or about            , 2007.

QUESTIONS AND ANSWERS ABOUT THE TRANSACTIONS

Q.
Please briefly describe the proposed transactions.

A.
GlobalSantaFe will merge (the "Merger") with Transocean Worldwide Inc., a recently formed subsidiary of Transocean ("Merger Sub"), by way of a scheme of arrangement qualifying as an amalgamation under Cayman Islands law, with the subsidiary of Transocean being the surviving entity following the Merger. Immediately prior to the Merger, outstanding Transocean ordinary shares will be reclassified into a smaller number of Transocean ordinary shares and cash by way of a separate scheme of arrangement (the "Reclassification"). We refer to the Merger and the Reclassification together as the "Transactions."

Q.
What will shareholders of Transocean and GlobalSantaFe receive as a result of the Transactions?

A.
As a result of the Transactions:

each Transocean ordinary share will be exchanged for 0.6996 Transocean ordinary shares and $33.03 in cash, and

each GlobalSantaFe ordinary share will be exchanged for 0.4757 Transocean ordinary shares (after giving effect to the Reclassification) and $22.46 in cash.
Q.
Why are Transocean and GlobalSantaFe proposing to merge?

A.
The boards of directors of Transocean and GlobalSantaFe believe that the combined company will be the drilling contractor of choice for customers, investors and employees and will offer:

Customers—consistently high quality drilling services with an increased worldwide presence, backed by technological expertise and financial strength;

Investors—an investment in a combined company that we believe will provide a platform for increased shareholder value creation; and

Employees—career opportunities with a financially strong company that is an industry leader in the application of offshore drilling technology.

Q.
Will the Transocean ordinary shares be traded on an exchange?

A.
We expect that the ordinary shares of Transocean received in the Transactions will be listed on the New York Stock Exchange under the ticker symbol "RIG."

Q.
Who will serve on the board of directors of Transocean after the consummation of the Transactions?

A.
Upon the consummation of the Transactions, the Transocean board of directors will consist of 14 members, seven of whom will be current members of the Transocean board of directors designated by Transocean and seven of whom will be current members of the GlobalSantaFe board of directors designated by GlobalSantaFe. Robert E. Rose, the current Chairman of the board of directors of GlobalSantaFe, will serve as Chairman of the board of directors of Transocean. Additional information about the composition of the board of directors of Transocean after the consummation of the Transactions is set forth in "The Transactions—Interests of Certain Persons in the Transactions—Governance and Management of Transocean Following the Transactions."

Q.
Who will serve as Transocean's executive officers after the consummation of the Transactions?

A.
Robert L. Long, the current Chief Executive Officer of Transocean, will serve

1


Q.
What are the U.S. federal income tax consequences of the Transactions?

A.
Transocean expects that the Reclassification will be treated as a stock redemption for U.S. federal income tax purposes. Assuming the Reclassification is treated as a stock redemption, then a shareholder who, actually or constructively, owns no GlobalSantaFe ordinary shares at the time of the Reclassification and the Merger should generally recognize gain or loss in an amount equal to the difference between the cash received from Transocean and the adjusted tax basis of the shares considered to be redeemed. However, alternative tax treatments are possible.
Q.
Do shareholders have appraisal rights?

A.
Under applicable law, none of the shareholders of Transocean or GlobalSantaFe has any right to receive an appraisal of the value of their shares in connection with the Transactions.

Q.
When do you expect the Transactions to be completed?

A.
We are working toward completing the Transactions as quickly as possible after all the conditions to the Transactions, including obtaining the approvals of our shareholders at the meetings, are fulfilled. Satisfying some of these conditions, including our receipt of governmental clearances or approvals and obtaining the approval of the Cayman Islands court, is not entirely within our control. We currently estimate that the parties will complete the Transactions by the end of 2007. However, the Transactions may not be completed until the first half of 2008.

Q.
What do I need to do to vote?

A.
Both companies' shareholder meetings will take place on            , 2007. After carefully reading and considering the information contained in this joint proxy statement and the documents incorporated by reference, please indicate on the enclosed proxy card how you want to vote. Mail your signed proxy card in the enclosed return envelope as soon as possible, so that your shares may be represented at your shareholder meeting. If you are a shareholder of both

Q.
What vote does my board of directors recommend?

A.
The Transocean board of directors unanimously recommends that Transocean's shareholders vote "FOR" each of the Reclassification, the issuance of ordinary shares to GlobalSantaFe shareholders in the Merger and the amendment and restatement of Transocean's articles of association and memorandum of association, each of which are conditions to the completion of the Transactions.
Q.
What should I do if I want to change my vote?

A.
You can change your vote at any time before your proxy card is voted at your shareholder meeting. You can do this in one of three ways:

you can send a written notice stating that you would like to revoke your proxy;

you can complete and submit a new proxy card; or

you can attend your meeting and vote in person.
Q.
What if I plan to attend the shareholder meeting in person?

A.
We recommend that you send in your proxy anyway. You may still attend your shareholder meeting and vote in person.

Q.
If my shares are held in "street name" by my broker, will my broker vote my shares for me without my instructions?

A.
We recommend that you contact your broker. Your broker can give you directions on how to instruct the broker to vote your shares. Your broker may not be able to vote your shares unless the broker receives appropriate instructions from you.

Q.
Should I send in my share certificates?

A.
No. After the Transactions are completed, we will send written instructions, including a letter of transmittal, which explains how to exchange GlobalSantaFe share certificates and old Transocean share certificates for new uncertificated Transocean shares and a check representing the applicable cash payment. Please do not send in any share certificates until you receive these written instructions and the letter of transmittal.

Q.
Will I receive certificates for the new Transocean shares?

A.
No. Transocean intends to implement a direct registration system for record holders at the closing of the Transactions under which all of the Transocean ordinary shares issued to record holders in the Transactions will be issued in uncertificated book-entry form rather than through share certificates. Holders of shares in street name through brokers or banks will continue to hold in street name unless other action is taken.

Q.
Whom do I call if I have questions about the meetings or the Transactions?

A.
Transocean's shareholders should contact either of the following:

("Goldman Sachs") delivered its oral opinion (which was subsequently confirmed in writing) to the Transocean board of directors to the effect that, as of such date and based upon and subject to the factors and assumptions set forth therein, and after taking into consideration the Reclassification, in the aggregate the 0.4757 Transocean ordinary shares and the $22.46 in cash to be paid by Transocean in respect of each GlobalSantaFe ordinary share pursuant to the merger agreement was fair from a financial point of view to Transocean.

("Lehman Brothers"), its financial advisor, that, as of the date of the opinion, the merger consideration to be offered to the GlobalSantaFe shareholders in the Merger is fair from a financial point of view to the holders of GlobalSantaFe ordinary shares. Lehman Brothers based its opinion on and delivered it subject to the assumptions, limitations and qualifications stated in the opinion.

        The full text of the written opinion of Lehman Brothers is attached as Annex C to this joint proxy statement. We encourage you to read the opinion carefully, as well as the description of the analyses and assumptions upon which the opinion was based.

Opinion of Simmons & Company International (page 74)

        In connection with the Merger, Simmons & Company International ("Simmons & Company") delivered a written opinion dated July 21, 2007, to the board of directors of GlobalSantaFe to the effect that, as of that date and based upon and subject to factors and assumptions set forth in its opinion, the merger consideration to be received by GlobalSantaFe's shareholders was fair to GlobalSantaFe's shareholders from a financial point of view. GlobalSantaFe's board of directors considered the opinion of Simmons & Company in deciding to approve the Merger.

        The full text of Simmons & Company's written opinion, dated July 21, 2007, is attached as Annex D to this joint proxy statement. Holders of GlobalSantaFe's ordinary shares are encouraged to read the opinion carefully in its entirety for a description of the procedures followed, assumptions made, matters considered and limitations on the scope of the review undertaken.

Overview of the Merger Agreement (page 115)

        The merger agreement is the document that governs the Transactions, although the Merger and Reclassification will be implemented by the schemes of arrangement. The merger agreement is attached as Annex A and the schemes of arrangement are attached as Annexes G and H to this joint proxy statement. We urge you to read these documents carefully.

        At the effective time of the Merger, GlobalSantaFe will merge with Transocean Worldwide Inc., a direct wholly owned subsidiary of Transocean ("Merger Sub"), by way of a scheme of arrangement qualifying as an amalgamation under Cayman Islands law, with Merger Sub being the surviving corporation.

        Immediately prior to the Merger, each outstanding ordinary share of Transocean will be reclassified by way of a scheme of arrangement under Cayman Islands law into 0.6996 Transocean ordinary shares and $33.03 in cash pursuant to the Reclassification.

7



        At the effective time of the Merger, each outstanding ordinary share of GlobalSantaFe will be exchanged for 0.4757 Transocean ordinary shares (after giving effect to the Reclassification) and $22.46 in cash.

        At the effective time of the Reclassification, each outstanding Transocean stock option will be adjusted in connection with the Transactions. Transocean deferred units and restricted shares will be exchanged for the same consideration for which each outstanding ordinary share of Transocean is exchanged in the Reclassification. However, the share consideration with respect to deferred unit and restricted share awards made between July 21, 2007 and the earlier of (1) the closing of the Transactions and (2) the termination of the merger agreement will remain subject to the vesting restrictions set forth in the applicable award agreement.

        At the effective time of the Merger, all outstanding GlobalSantaFe stock options and stock appreciation rights will be assumed by Transocean and converted into awards to receive Transocean ordinary shares. Each GlobalSantaFe restricted stock unit will be exchanged for the same consideration for which an ordinary share of GlobalSantaFe is exchanged in the Merger.

Conditions to the Transactions (page 128)

        The completion of the Transactions depends on a number of conditions, including the following:

8


        Each of the following is also a condition to the completion of the Transactions:


and either the failure to observe such waiting period or such claim, proceeding or action or such order described in the preceding three bullet points is reasonably likely to require either Transocean or GlobalSantaFe to dispose of assets or limit its freedom of action, except for such dispositions or limits that, in the reasonable good faith judgment of both Transocean and GlobalSantaFe, do not and are not reasonably likely to have a material adverse effect on Transocean or GlobalSantaFe, materially impair the benefits or advantages Transocean or GlobalSantaFe expect to receive from the Merger and the transactions contemplated by the merger agreement or have a material adverse effect on the business plan or business strategy for the combined company.

Termination of the Merger Agreement (page 131)

        The merger agreement may be terminated by the mutual written consent of Transocean and GlobalSantaFe. In addition, either Transocean or GlobalSantaFe may terminate the merger agreement if:

        The merger agreement may also be terminated by Transocean if:

9


        The merger agreement may also be terminated by GlobalSantaFe if:

Termination Fees and Expenses (page 133)

        GlobalSantaFe will be required to pay a $300 million termination fee if the merger agreement is terminated:

        Transocean will be required to pay a $300 million termination fee if the merger agreement is terminated:

10


        If the merger agreement is terminated by either party due to failure to obtain the requisite approval of a party's shareholders, and a termination fee is not otherwise payable upon such termination as described above, the party failing to obtain shareholder approval will be required to pay the termination fee where:

        If the merger agreement is terminated by either party due to the failure to obtain one party's shareholder approval or due to an adverse recommendation change by a party, and no termination fee is otherwise required to be paid under the merger agreement, then the party failing to obtain shareholder approval or whose board of directors made the adverse recommendation change will reimburse the other party for its third party costs and expenses in connection with the Transactions, up to a maximum of $30 million.

No Solicitation (page 119)

        The merger agreement contains detailed provisions prohibiting either party from seeking an alternative transaction. These "no solicitation" provisions generally prohibit either party from taking any action to solicit a competing proposal. The merger agreement does not, however, prohibit either party or its respective board of directors from considering, and potentially recommending, an unsolicited written proposal from a third party.

Interests of Certain Persons in the Transactions (page 81)

        In considering the boards' recommendations, shareholders should be aware that some officers and directors of Transocean and GlobalSantaFe may have interests in the Transactions that are different from, or in addition to, those of shareholders generally:

11


Regulatory Clearances (page 109)

        Transocean and GlobalSantaFe have made or will make appropriate filings to obtain clearances of the Merger from governmental regulators, including competition and antitrust authorities in the United States, the United Kingdom and Brazil.

        We are working to obtain the required regulatory clearances. Although we have not yet received the required clearances, we estimate that we will receive regulatory clearances in sufficient time to complete the Transactions by the end of 2007. However, we can give no assurance as to when or whether these clearances will be obtained or the terms and conditions that these clearances may impose.

Accounting Treatment and Considerations (page 95)

        Transocean will account for the Reclassification as a reverse stock split and dividend. Transocean will account for the Merger using the purchase method of accounting with Transocean treated as the acquiror. As the accounting acquiror, Transocean's assets and liabilities will remain at historical amounts.

        In applying purchase accounting, Transocean will record the assets and liabilities of GlobalSantaFe at their estimated fair values at the closing date of the Transactions with the excess of the purchase price over the sum of such fair values recorded as goodwill. The purchase price is calculated using the estimated number of Transocean ordinary shares to be issued in the Merger using the average trading price of Transocean ordinary shares for a period of time immediately before and after the Merger was announced, plus estimated cash consideration to be paid to GlobalSantaFe shareholders based on the number of GlobalSantaFe ordinary shares estimated to be

12


outstanding at the time of the Merger and cash consideration of $22.46 per share, plus estimated direct Merger costs and expenses and plus the estimated fair value of GlobalSantaFe stock options and SARs to be assumed by Transocean.

        The estimated dividend to Transocean shareholders is calculated based on the number of Transocean ordinary shares estimated to be outstanding at the time of the Reclassification.

Material U.S. Federal Income Tax Consequences (page 96)

        Transocean expects that the Reclassification will be treated as a stock redemption for U.S. federal income tax purposes. Assuming the Reclassification is treated as a stock redemption, then a shareholder who, actually or constructively, owns no GlobalSantaFe ordinary shares at the time of the Reclassification and the Merger should generally recognize gain or loss in an amount equal to the difference between the cash received from Transocean and the adjusted tax basis of the shares considered to be redeemed. However, alternative tax treatments are possible.

        The Merger is expected to qualify as a reorganization under section 368(a) of the Internal Revenue Code for U.S. federal income tax purposes. Assuming it does so qualify, GlobalSantaFe shareholders will generally recognize gain (but not loss) in an amount equal to the lesser of the cash received by the shareholder and the excess, if any, of (1) the sum of the cash and the fair market value of the Transocean ordinary shares received by the shareholder over (2) the shareholder's adjusted tax basis in the GlobalSantaFe ordinary shares exchanged in the Merger. Under certain circumstances this gain could be taxable as a dividend to the extent of the shareholder's ratable share of available earnings and profits.

        Please refer to "Material U.S. Federal Income Tax Consequences," beginning on page 96 of this joint proxy statement for a description of the material U.S. federal income tax consequences of the Reclassification to Transocean shareholders and the Merger to GlobalSantaFe shareholders. Determining the actual tax consequences to you of the Reclassification or Merger may be complex and will depend on your specific situation. You are urged to consult your tax adviser for a full understanding of the tax consequences of the Reclassification or Merger to you.

No Appraisal Rights

        Under applicable law, none of the shareholders of Transocean or GlobalSantaFe has any right to an appraisal of the value of their shares or payment for them in connection with the Transactions.

Listing of Transocean Ordinary Shares (page 113)

        Transocean will apply to list the ordinary shares to be issued in the Transactions on the New York Stock Exchange.

Comparison of Rights of Shareholders (page 160)

        The rights of Transocean ordinary shareholders and GlobalSantaFe ordinary shareholders are governed by the Companies Law of the Cayman Islands and the memorandum of association and articles of association of the respective company. When the Transactions are completed, Transocean ordinary shareholders and GlobalSantaFe ordinary shareholders will both be Transocean ordinary shareholders, and their rights will be governed by the Companies Law of the Cayman Islands and Transocean's amended and restated memorandum of association and amended and restated articles of association. See pages 160 through 165 for more specific information.

Market Price and Dividend Information (page 142)

        Transocean ordinary shares and GlobalSantaFe ordinary shares are both quoted on the New York Stock Exchange. On July 20, 2007, the last trading day before we announced the Transactions, Transocean ordinary shares closed at $109.97 per share and GlobalSantaFe ordinary shares closed at $74.74 per share. On    2007, the most recent practicable date before the date of this joint proxy statement, Transocean ordinary shares closed at $    per share and

13



GlobalSantaFe ordinary shares closed at $    per share. The market price of Transocean shares will fluctuate before and after the Transactions, but the consideration for Transocean and GlobalSantaFe shareholders in the Transactions is fixed. You should obtain current share price quotations for Transocean ordinary shares and GlobalSantaFe ordinary shares.

        GlobalSantaFe has paid quarterly cash dividends of $0.225 per ordinary share since the first quarter of 2006 until the second quarter of 2007. Transocean does not generally pay cash dividends. Each of Transocean and GlobalSantaFe is prohibited from declaring cash dividends under the terms of the merger agreement. The bridge loan facility is expected to contain covenants restricting the combined company's ability to pay dividends. The new board of directors of Transocean will decide whether to pay quarterly cash dividends after the completion of the Transactions.

RISK FACTORS

        In addition to the other information contained in this joint proxy statement and the documents incorporated by reference, including, without limitation, Transocean's Annual Report on Form 10-K for the year ended December 31, 2006 and GlobalSantaFe's Annual Report on Form 10-K for the year ended December 31, 2006, you should carefully consider the following risk factors before you decide how to vote on the proposals.


Risks Relating to the Transactions

        The value of the Transocean ordinary shares to be received in the Transactions will fluctuate.

        The merger agreement does not contain any provisions for adjustment of the consideration and does not provide for rights of termination by either party based upon fluctuations in the market price of the Transocean ordinary shares before the completion of the Transactions. Because no adjustment will be made to the consideration, the market value of the Transocean ordinary share consideration to be received by Transocean and GlobalSantaFe shareholders in connection with the Transactions cannot presently be determined and will vary based upon the market price of Transocean ordinary shares at the time the Transactions are completed. These variations may be the result of:

        GlobalSantaFe's shareholders are urged to obtain current market quotations for their shares and for Transocean ordinary shares.

        Failure to complete, or delays in completing, the Transactions could negatively impact the market price of the Transocean and GlobalSantaFe ordinary shares and financial results of Transocean and GlobalSantaFe.

        Completion of the proposed Transactions is subject to various conditions, including, among others, approval by shareholders of Transocean and GlobalSantaFe and obtaining regulatory clearances and financing sufficient to enable Transocean to deliver the cash consideration to the shareholders of Transocean and GlobalSantaFe payable by virtue of the Transactions. If these or other conditions are not satisfied or if there is a delay in the satisfaction of such conditions, then Transocean and GlobalSantaFe may not be able to complete the Transactions timely or at all, and such failure or delay

20


may have other adverse consequences. If the Transactions are not completed or are delayed, Transocean and GlobalSantaFe will be subject to a number of risks, including:

        While the Transactions are pending, Transocean and GlobalSantaFe may experience diminished productivity due to the impact of the Transactions on their current and prospective employees, key management, customers, suppliers and business partners.

        Management of Transocean and GlobalSantaFe may be required to devote substantial time to activities related to the Transactions, which could otherwise be devoted to pursuing other beneficial business opportunities. Furthermore, current and prospective employees of Transocean and GlobalSantaFe may be uncertain about their future roles and relationships with the companies following the completion of the Transactions. This focus of management on the Transactions and employee uncertainty may also affect the productivity of Transocean and GlobalSantaFe or adversely affect each company's ability to attract and retain key management and employees.

        Customers and business partners may not be as willing to continue to do business with Transocean or GlobalSantaFe on the same or similar terms or may delay or defer decisions relating to their business relationships with Transocean or GlobalSantaFe pending the completion of the Transactions, which could materially and adversely affect each company's business and results of operations. In addition, the merger agreement generally restricts Transocean and GlobalSantaFe, without the other party's consent, from taking actions outside the ordinary course of business or from taking other specified actions until the Merger occurs or the merger agreement terminates. These restrictions may prevent Transocean and GlobalSantaFe from taking actions that each might otherwise consider beneficial.

        Until the Transactions are completed or the merger agreement is terminated, under certain circumstances, neither Transocean nor GlobalSantaFe will be able to enter into a merger or business combination with another party on favorable terms because of restrictions in the merger agreement.

        Unless and until the merger agreement is terminated, subject to specified exceptions (which are discussed in more detail under "The Merger Agreement"), Transocean and GlobalSantaFe are restricted from soliciting, initiating or knowingly encouraging any inquiry, proposal or offer for an alternative transaction with any person. Transocean and GlobalSantaFe may terminate the merger agreement and enter into an agreement with respect to a superior proposal only if specified conditions have been satisfied, including compliance by the terminating party in all material respects with these non-solicitation provisions, allowing the other party seven days (or five days with respect to any material revision) to propose an adjustment to the terms and conditions of the merger agreement and paying a $300 million termination fee. These restrictions could affect the structure, pricing and other terms proposed by other parties seeking to enter into an alternate transaction with Transocean or GlobalSantaFe and, as a result of these restrictions, neither Transocean nor GlobalSantaFe may be able

21



to enter into an agreement with respect to an alternative transaction on more favorable terms without incurring potentially significant liability to the other.

        As a result of the Transactions, Transocean's overall debt level will increase, and it may lose the ability to obtain future financing and lose its competitive advantage.

        As a result of the Transactions, Transocean's overall debt level will increase from approximately $3.1 billion at June 30, 2007, to approximately $18.8 billion at such date on a pro forma basis after giving effect to the Transactions. After the completion of the Transactions, Transocean's level of debt and other obligations could have significant adverse consequences on the business and future prospects of the combined company, including the following:

        Transocean may not be successful in refinancing the proposed bridge loan facility, and the terms of any refinancing may not be favorable to Transocean.

        The proposed bridge loan facility has a maturity of one year. Although Transocean expects to refinance this debt on more favorable terms after the Transactions, such refinancing is subject to conditions in the credit markets, which are currently volatile, and there can be no assurance that Transocean will be successful in refinancing the debt or that the terms of the refinancing will be favorable to Transocean, which could adversely affect the combined company's results of operations or financial condition.

        Transocean's overall debt level following the Transactions and/or its inability to refinance the bridge loan facility on favorable terms could lead the credit rating agencies to lower the corporate credit ratings of Transocean following the Transactions below currently expected levels and possibly below investment grade.

        Market conditions could prohibit Transocean from refinancing the bridge loan facility at favorable rates and terms, which could limit its ability to efficiently repay debt and could cause Transocean to maintain a high level of leverage or issue debt with unfavorable terms and conditions. This leverage level could lead the credit rating agencies to downgrade the credit ratings of Transocean following the Transactions below currently expected levels and possibly to non-investment grade levels. Such ratings levels could negatively impact current and prospective customers' willingness to transact business with Transocean. Suppliers may lower or eliminate the level of credit provided through payment terms when dealing with Transocean thereby increasing the need for higher levels of cash on hand, which would decrease Transocean's ability to repay the debt balances as the parties currently anticipate.

        The anticipated benefits of combining the companies may not be realized, and there may be difficulties in integrating the operations of Transocean and GlobalSantaFe.

        Transocean and GlobalSantaFe entered into the merger agreement with the expectation that the Transactions would result in various benefits, including, among other things, synergies, cost savings and operating efficiencies. See "The Transactions—Transocean's Reasons for the Transactions" and "The Transactions—GlobalSantaFe's Reasons for the Transactions." The combined company may not achieve these benefits at the levels expected or at all. If the combined company fails to achieve these expected

22



benefits, the results of operations and the enterprise value of the combined company may be adversely affected.

        Prior to the consummation of the Transactions, Transocean and GlobalSantaFe will continue to operate as separate companies. The combined company may not be able to integrate the operations of Transocean and GlobalSantaFe without a loss of employees, customers or suppliers, a loss of revenues, an increase in operating or other costs or other difficulties. In addition, the combined company may not be able to realize the operating efficiencies, synergies, cost savings or other benefits expected from the Transactions. Any unexpected delays incurred in connection with the integration could have an adverse effect on the combined company's business, results of operations or financial condition.

        Transocean and GlobalSantaFe will incur significant transaction and merger-related integration costs in connection with the Transactions.

        Transocean and GlobalSantaFe expect to incur costs associated with consummating the Transactions and integrating the operations of the two companies of approximately $372 million. These costs include investment banking, financing, legal and accounting fees and expenses, SEC filing fees, printing expenses, mailing expenses and other related charges, severance and retention costs, change in control costs, and benefit plan harmonization costs. These amounts are preliminary estimates that are subject to change. A portion of these costs will be incurred regardless of whether the Transactions are completed.

        Some of the directors and executive officers of Transocean and GlobalSantaFe have interests in the Transactions that are different from the interests of the shareholders of Transocean and GlobalSantaFe.

        When considering the recommendation of the Transocean board of directors with respect to the Reclassification, the issuance of Transocean ordinary shares in the Merger and the amendment and restatement of Transocean's memorandum of association and articles of association, Transocean shareholders should be aware that some directors and executive officers of Transocean have interests in the Transactions that are different from, or in addition to, the interests of the shareholders of Transocean. These interests include (1) their designation as directors or officers of the combined company, (2) the fact that the completion of the Transactions will result in the acceleration of vesting of equity-based awards held by directors and executive officers and certain cash-based awards held by executive officers, (3) the fact that certain executive officers of Transocean are participants under Transocean's Executive Change-of-Control Severance Benefit that will entitle them to cash payments and other benefits if the Transactions are completed and their employment is terminated or if the executive resigns for good reason, as defined in the policy and (4) their indemnification by Transocean.

        When considering the recommendation of the GlobalSantaFe board of directors with respect to the Merger, GlobalSantaFe shareholders should be aware that some directors and officers of GlobalSantaFe have interests in the Transactions that are different from, or in addition to, the interests of the shareholders of GlobalSantaFe. These interests include (1) their designation as directors or executive officers of the combined company, (2) the fact that shareholder approval of the Merger or, in some cases, the completion of the Transactions, will result in the acceleration of vesting of equity-based awards held by directors and executive officers, (3) the fact that certain executive officers of GlobalSantaFe have entered into change of control agreements with GlobalSantaFe that will entitle them to cash payments and other benefits if the Transactions are completed and their employment is terminated or if the executive terminates his or her employment for good reason, as defined in the agreements, and (4) their indemnification by Transocean.

23



        Shareholders should consider these interests in conjunction with the recommendation of the directors of Transocean and GlobalSantaFe of approval of the Transactions. These interests have been described more fully in "The Transactions—Interests of Certain Persons in the Transactions."

        Transocean is subject to anti-takeover provisions.

        Transocean's articles of association contain provisions that could prevent or delay an acquisition of the company by means of a tender offer, a proxy contest or otherwise. These provisions may also adversely affect prevailing market prices for Transocean's ordinary shares. These provisions, among other things:

        Upon completion of the Transactions, in addition to the foregoing, the Transocean board of directors will be comprised of seven persons designated by Transocean and seven persons designated by GlobalSantaFe (or their replacements designated by the applicable group of directors) for two years after the date of the completion of the Transactions. Under the amended and restated articles of association of Transocean that will be in effect after the completion of the Transactions, at each annual general meeting held during the two years following the completion of the Transactions, each such director whose term expires during such period will be nominated for re-election (or another person selected by the applicable group of directors will be nominated for election) to the Transocean board of directors.

Risks Relating to the Business of the Combined Company Following the Completion of Transactions

        The business of the combined company depends on the level of activity in the offshore oil and gas industry, which is significantly affected by volatile oil and gas prices and other factors.

        The combined company's business depends on the level of activity in oil and gas exploration, development and production in market sectors worldwide, with the U.S. and international offshore areas being the combined company's primary market sectors. Oil and gas prices and market expectations of potential changes in these prices significantly affect this level of activity. However, higher commodity prices do not necessarily translate into increased drilling activity since customers' expectations of future commodity prices typically drive demand for the combined company's rigs. Also, increased competition for customers' drilling budgets could come from, among other areas, land-based energy markets in Africa, Russia, other former Soviet Union States, the Middle East and Alaska. The availability of quality drilling prospects, exploration success, relative production costs, the stage of reservoir development and political and regulatory environments also affect customers' drilling campaigns. Worldwide military, political and economic events have contributed to oil and gas price volatility and are likely to do so in the future. Oil and gas prices are extremely volatile and are affected by numerous factors, including the following:

        The combined company's industry will be highly competitive and cyclical, with intense price competition.

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

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

25


        During prior periods of high utilization and dayrates, industry participants have increased the supply of rigs by ordering the construction of new units. This has typically resulted in an oversupply of drilling units and has caused a subsequent decline in utilization and dayrates, sometimes for extended periods of time. There are numerous high-specification rigs and jackups under contract for construction and mid-water semisubmersibles that are being upgraded to enhance their operating capability. The entry into service of these new and upgraded units will increase supply and could curtail a further strengthening of dayrates, or reduce them, as rigs are absorbed into the active fleet. Any further increase in construction of new drilling units would likely exacerbate the negative impact on utilization and dayrates. Lower utilization and dayrates in one or more of the regions in which the combined company will operate could adversely affect the combined company's revenues and profitability. Prolonged periods of low utilization and dayrates could also result in the recognition of impairment charges on certain classes of the combined company's drilling rigs or goodwill balance if future cash flow estimates, based upon information available to management at the time, indicate that the carrying value of these rigs, or the goodwill balance, may not be recoverable.

        The combined company's business involves numerous operating hazards.

        The combined company's operations will be subject to the usual hazards inherent in the drilling of oil and gas wells, such as blowouts, reservoir damage, loss of production, loss of well control, punch-throughs, craterings, fires and natural disasters such as hurricanes and tropical storms. The occurrence of these events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury or death to rig personnel. The combined company will also be subject to personal injury and other claims of rig personnel as a result of its drilling operations. Operations also may be suspended because of machinery breakdowns, abnormal drilling conditions, failure of subcontractors to perform or supply goods or services, or personnel shortages. In addition, offshore drilling 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 the combined company's operations, particularly through oil spillage or extensive uncontrolled fires. The combined company may also be subject to property, environmental and other damage claims by oil and gas companies. The combined company's insurance policies and contractual rights to indemnity may not adequately cover losses, and it will not have insurance coverage or rights to indemnity for all risks.

        Consistent with standard industry practice, the combined company's clients generally assume, and indemnify it against, well control and subsurface risks under dayrate contracts. These are risks 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. However, there can be no assurance that these clients will necessarily be financially able to indemnify the combined company against all these risks. Also, the combined company may be effectively prevented from enforcing these indemnities because of the nature of its relationship with some of its larger clients.

        Transocean has maintained and the combined company is expected to maintain broad insurance coverage, including coverage for property damage, occupational injury and illness, and general and marine third-party liabilities. Property damage insurance covers against marine and other perils, including losses due to capsizing, grounding, collision, fire, lightning, hurricanes and windstorms (excluding named storms in the U.S. Gulf of Mexico, for which we generally have no coverage), action of waves, punch-throughs, cratering, blowouts and explosion. However, the combined company may maintain large self-insured deductibles for damage to its offshore drilling equipment and third-party liabilities similar to Transocean's current coverage. Prior to the Transactions, Transocean has generally maintained a $125 million per occurrence insurance deductible on hull and machinery (subject to an aggregate annual deductible of $250 million), a $10 million per occurrence deductible on personal injury liability for crew claims ($5 million for non-crew claims) and a $5 million per occurrence

26



deductible on third-party property damage. In addition to the per occurrence deductibles described above, Transocean also has an aggregate deductible of $50 million in the case of its personal injury liability and third-party property damage coverage that is applied to any occurrence in excess of the per occurrence deductible until the aggregate deductible is exhausted. These deductibles are significantly higher than those under GlobalSantaFe's current coverages. Transocean does not generally have coverage for losses due to hurricanes in the U.S Gulf of Mexico and war perils worldwide. Transocean generally insures all of its offshore drilling rigs against property damage, except for U.S Gulf of Mexico windstorm risk and war perils worldwide and subject to self-insured deductibles as described above; however, the amount of such insurance may be less than the related impact on enterprise value after a loss.

        The combined company's insurance coverage will not in all situations provide sufficient funds to protect it from all liabilities that could result from its drilling operations. The combined company's coverage will include annual aggregate policy limits. As a result, the combined company will retain the risk through self-insurance for any losses in excess of these limits. Although GlobalSantaFe currently maintains loss of hire coverage, the combined company may not carry insurance for loss of revenue and certain other claims may not be reimbursed by insurance carriers. Any such lack of reimbursement may cause the combined company to incur substantial costs. In addition, the combined company could decide to retain substantially more risk through self-insurance.

        Failure to obtain and retain key personnel could hurt the combined company's operations.

        The combined company will require highly skilled personnel to operate and provide technical services and support for its drilling units and drilling management services. Competition for the labor required for drilling operations, including for turnkey drilling and drilling management services businesses and construction projects, has intensified as the number of rigs activated, added to worldwide fleets or under construction has increased, leading to shortages of qualified personnel in the industry and creating upward pressure on wages and possibly higher turnover. If turnover increases, the combined company could see a reduction in the experience level of its personnel, which could lead to higher downtime and more operating incidents, which in turn could decrease revenues and increase costs. In response to these labor market conditions, Transocean and GlobalSantaFe are increasing efforts in their recruitment, training, development and retention programs as required to meet the combined company's anticipated personnel needs. If these labor trends continue, the combined company may experience further increases in costs or limits on operations.

        Labor costs and the operating restrictions under which the combined company will operate could increase as a result of collective bargaining negotiations and changes in labor laws and regulations.

        Some of the employees and contracted labor of Transocean and GlobalSantaFe work under collective bargaining agreements, and most of these employees and contracted labor work in the United Kingdom, Nigeria and Norway. Many of these represented individuals are working under agreements that are subject to salary negotiation in 2007. These negotiations could result in higher personnel expenses, other increased costs or increased operating restrictions. Additionally, the unions in the United Kingdom are seeking an interpretation of the Offshore Working Directive, which was recently extended to include U.K. offshore workers, that could result in higher labor costs and undermine the combined company's ability to obtain a sufficient number of skilled workers in the United Kingdom.

        Shipyard projects and other operations are subject to delays and cost overruns.

        The combined company has committed to five deepwater new build rig projects and two Sedco 700-series rig upgrades, and Transocean and GlobalSantaFe are each discussing other potential newbuild opportunities with several oil and gas company clients. The combined company will also have a variety of other more limited shipyard projects at any given time. These shipyard projects are subject

27



to the risks of delay or cost overruns inherent in any such construction project resulting from numerous factors, including the following:

        These factors may contribute to cost variations and delays in the delivery of the combined company's upgraded and newbuild units and other rigs undergoing shipyard projects. Delays in the delivery of these units would result in delay in contract commencement, resulting in a loss of revenue to the combined company, and may also cause customers to terminate or shorten the term of the drilling contract for the rig pursuant to applicable late delivery clauses. In the event of termination of one of these contracts, the combined company may not be able to secure a replacement contract on as favorable terms.

        The operations of the combined company will also rely on a significant supply of capital and consumable spare parts and equipment to maintain and repair its fleet. It will also rely on the supply of ancillary services, including supply boats and helicopters. Recently, Transocean and GlobalSantaFe have experienced increased delivery times from vendors due to increased drilling activity worldwide and the increase in construction and upgrade projects, and have also experienced a tightening in the availability of ancillary services. Transocean is in the process of replacing its primary global logistics provider, which may result in delays and disruptions, and potentially increased costs, in some operations. Shortages in materials, delays in the delivery of necessary spare parts, equipment or other materials, or the unavailability of ancillary services could negatively impact the future operations of the combined company and result in increases in rig downtime, and delays in the repair and maintenance of its fleet.

        A loss of a major tax dispute or a successful challenge to the combined company's tax structure could result in a significant loss or in a higher tax rate on the combined company's worldwide earnings or both.

        The combined company will be a Cayman Islands company and also will operate through various subsidiaries around the world. The combined company's income taxes will be based upon the applicable tax laws and tax rates in effect in the countries in which it will operate and upon how it is structured in these countries. Its income tax returns will be subject to review and examination in such countries. The combined company will not recognize the benefit of income tax positions it believes are more likely than not to be disallowed upon challenge by a tax authority. If any tax authority successfully challenges the combined company's operational structure, intercompany pricing policies, the tax presence of key combined company entities in certain countries, or if the terms of certain income tax treaties are changed in a manner that is adverse to the combined company's structure, or if the combined company loses a material dispute in any country, particularly in the United States and Norway, its effective tax rate on its worldwide earnings could increase substantially and its financial results could be materially adversely affected.

28



        A change in tax laws, treaties or regulations, or their interpretation, of any country in which the combined company operates could result in a higher or lower tax rate on its worldwide earnings.

        The combined company will operate worldwide through its various subsidiaries in a number of countries throughout the world. Consequently, the combined company will be subject to tax laws, treaties and regulations in and between the countries in which it operates. A change in those tax laws, treaties or regulations could result in a higher or lower effective tax rate on the combined company's worldwide earnings.

        One such treaty is currently in the process of being renegotiated. This renegotiation will likely result in a change in the terms of the treaty that is adverse to the combined company's structure, which in turn would increase its effective tax rate, and such increase could be material. We are monitoring the progress of the treaty renegotiation with a view to determining what, if any, steps are appropriate to mitigate any potential negative impact. The combined company may not be able to fully, or partially, mitigate any negative impact of this treaty renegotiation or any other future changes in treaties.

        Various proposals have been made in recent years that, if enacted into law, could have an adverse impact on the combined company. Examples include, but are not limited to, proposals that would broaden the circumstances in which a non-U.S. company would be considered U.S. resident and a proposal that could limit treaty benefits on certain payments by U.S. subsidiaries to non-U.S. affiliates. Such legislation, if enacted, could cause a material increase in the combined company's tax liability and effective tax rate.

        The combined company's non-U.S. operations will involve additional risks not associated with its U.S. operations.

        The combined company will operate in various regions throughout the world, which may expose it to political and other uncertainties, including risks of:

        The combined company will be protected to a substantial extent against loss of capital assets, but generally not loss of revenue, from most of these risks through indemnity provisions in its drilling contracts. Effective May 1, 2007, Transocean's assets are generally not insured against risk of loss due to perils such as terrorist acts, civil unrest, expropriation, nationalization and acts of war. Pollution and environmental risks generally are not totally insurable. If a significant accident or other event occurs and is not fully covered by insurance or an enforceable or recoverable indemnity from a client, it could adversely affect the combined company's consolidated financial position, results of operations or cash flows.

        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 the combined company's ability to compete.

        The combined company's non-U.S. contract drilling operations will be subject to various laws and regulations in countries in which the combined company will operate, including laws and regulations relating to the equipment and operation of drilling units, currency conversions and repatriation, oil and gas exploration and development and taxation of offshore earnings and earnings of expatriate personnel. Governments in some foreign countries have become increasingly active in regulating and controlling the ownership of concessions and companies holding concessions, the exploration for oil and gas and other aspects of the oil and gas industries in their countries. In addition, government action, including initiatives by OPEC, may continue to cause oil or gas price volatility. In some areas of the

29



world, this governmental activity has adversely affected the amount of exploration and development work done by major oil companies and may continue to do so.

        Another risk inherent in the combined company's operations is the possibility of currency exchange losses where revenues are received and expenses are paid in nonconvertible currencies. The combined company may also incur losses as a result of an inability to collect revenues because of a shortage of convertible currency available in the country of operation.

        Failure to comply with the U.S. Foreign Corrupt Practices Act could result in fines, criminal penalties, drilling contract terminations and an adverse effect on the combined company's business.

        In June 2007, GlobalSantaFe's management retained independent outside counsel to conduct an internal investigation of its Nigerian and West African operations, focusing on brokers who handled customs matters with respect to its affiliates operating in those jurisdictions and whether those brokers have fully complied with the U.S. Foreign Corrupt Practices Act ("FCPA") and local laws. GlobalSantaFe commenced its investigation following announcements by other oilfield service companies that they were independently investigating the FCPA implications of certain actions taken by third parties in respect of customs matters in connection with their operations in Nigeria, as well as another company's recently announced settlement implicating a third party handling customs matters in Nigeria. In each case, the customs broker was reported to be Panalpina Inc., whom GlobalSantaFe used to obtain temporary import permits for its rigs operating offshore Nigeria. GlobalSantaFe voluntarily disclosed its internal investigation to the U.S. Department of Justice (the "DOJ") and the U.S. Securities and Exchange Commission (the "SEC") and, at their request, has expanded its investigation to include the activities of its customs brokers in other West African countries and the activities of one customs broker worldwide. The investigation is focusing on whether the brokers have fully complied with the requirements of their contracts, local laws and the FCPA. GlobalSantaFe's legal representatives are keeping the DOJ and SEC apprised of the scope and details of their investigation and producing relevant information in response to their requests. The audit committee of GlobalSantaFe's board of directors has had unfettered access to the independent outside counsel, and the general counsel and outside counsel have provided periodic updates to the committee during its meetings and to the chairman of the committee between such meetings as circumstances warrant. Should the investigation not be concluded prior to the effective date of the Transactions, it is anticipated that the independent outside counsel will begin formally reporting directly to the audit committee of the combined company. GlobalSantaFe cannot predict at this time the ultimate outcome of the investigation, the effect of implementing any further measures that may be necessary to ensure full compliance with applicable laws or to what extent, if at all, it could be subject to fines, sanctions or other penalties.

        On July 25, 2007, Transocean's legal representatives met with the DOJ in response to a notice Transocean received requesting such a meeting regarding its engagement of Panalpina Inc. for freight forwarding and other services in the United States and abroad. The DOJ has informed Transocean that it is conducting an investigation of alleged FCPA violations by oil service companies who used Panalpina, Inc. and other brokers in Nigeria and other parts of the world. Transocean began developing an investigative plan which would allow it to promptly review and produce relevant and responsive information requested by the DOJ.

        Subsequently, Transocean expanded the investigation to include one of Transocean's agents for Nigeria. The investigation is being conducted by outside counsel who reports directly to the Audit Committee of Transocean's board of directors. The investigation has focused on whether the customs brokers and agent have fully complied with the terms of their respective agreements, the FCPA and local laws. Transocean has prepared and presented an investigative plan to the DOJ and has informed the SEC of the ongoing investigation. Transocean cannot predict the ultimate outcome of the investigation, the effect of implementing any further measures that may be necessary to ensure full

30



compliance with applicable laws or to what extent, if at all, it could be subject to fines, sanctions or other penalties.

        The GlobalSantaFe and Transocean investigations include a review of amounts paid to and by customs brokers in connection with the obtaining of permits for the temporary importation of vessels and the clearance of goods and materials. These permits and clearances are necessary in order for GlobalSantaFe and Transocean to operate their vessels in certain jurisdictions. There is a risk that either GlobalSantaFe or Transocean may not be able to obtain import permits or renew temporary importation permits in West African countries, including Nigeria, in a manner that complies with the FCPA. As a result, either GlobalSantaFe or Transocean may not have the means to renew temporary importation permits for rigs located in the relevant jurisdictions as they expire or to send goods and equipment into those jurisdictions, in which event such company may be forced to terminate the pending drilling contracts and relocate the rigs or leave the rigs in these countries and risk permanent importation issues, either of which could have an adverse effect on their or the combined company's financial results. In addition, termination of drilling contracts could result in damage claims by customers.

        The combined company's operating and maintenance costs will not necessarily fluctuate in proportion to changes in operating revenues.

        The combined company's operating and maintenance costs will not necessarily fluctuate in proportion to changes in operating revenues. Operating revenues may fluctuate as a function of changes in dayrate. However, costs for operating a rig are generally fixed or only semi-variable regardless of the dayrate being earned. In addition, should the combined company's rigs incur idle time between contracts, the combined company typically will not de-man those rigs because it will use the crew to prepare the rig for its next contract. During times of reduced activity, reductions in costs may not be immediate as portions of the crew may be required to prepare rigs for stacking, after which time the crew members are assigned to active rigs or dismissed. In addition, as the combined company's rigs are mobilized from one geographic location to another, the labor and other operating and maintenance costs can vary significantly. In general, labor costs increase primarily due to higher salary levels and inflation. Equipment maintenance expenses fluctuate depending upon the type of activity the unit is performing and the age and condition of the equipment. Contract preparation expenses vary based on the scope and length of contract preparation required and the duration of the firm contractual period over which such expenditures are amortized.

        The combined company's drilling contracts may be terminated due to a number of events.

        The combined company's customers may terminate or suspend some of its term drilling contracts without paying a termination fee under various circumstances such as the loss or destruction of the drilling unit, downtime or impaired performance caused by equipment or operational issues, some of which will be beyond the combined company's control, or sustained periods of downtime due to force majeure events. Suspension of drilling contracts results in loss of the dayrate for the period of the suspension. If the combined company's customers cancel some of its significant contracts and the combined company is unable to secure new contracts on substantially similar terms, it could adversely affect the combined company's results of operations. In reaction to depressed market conditions, customers may also seek renegotiation of firm drilling contracts to reduce their obligations.

        The combined company will be subject to litigation that, if not resolved in its favor and not sufficiently insured against, could have a material adverse effect on the combined company.

        The combined company will be subject to a variety of litigation and may be sued in additional cases. Certain subsidiaries of GlobalSantaFe and, to a lesser extent, certain subsidiaries of Transocean, are named as defendants in numerous lawsuits alleging personal injury as a result of exposure to

31



asbestos, silicosis, exposure to toxic fumes or other occupational diseases and medical issues that can remain undiscovered for a considerable amount of time. Some of these subsidiaries that have been put on notice of potential liabilities have no assets. Other subsidiaries are subject to litigation relating to environmental damage. GlobalSantaFe and Transocean cannot predict the outcome of these cases involving their respective subsidiaries or the potential costs to resolve them. Insurance may not be applicable or sufficient in all cases, insurers may not remain solvent, and policies may not be located. Suits against non-asset-owning subsidiaries have and may in the future give rise to alter ego or successor in interest claims against the combined company and its asset-owning subsidiaries to the extent a subsidiary is unable to pay a claim or insurance is not available or sufficient to cover the claims. To the extent that one or more pending or future litigation matters are not resolved in the combined company's favor and are not covered by insurance, a material adverse effect on the combined company's financial results and condition could result.

        Turnkey drilling operations expose the combined company to additional risks, which can adversely affect the combined company's profitability, because it assumes the risk for operational problems and the contracts are on a fixed-price basis.

        The combined company will conduct most of its drilling services under dayrate drilling contracts where the customer pays for the period of time required to drill or work over a well. However, GlobalSantaFe enters into, and, after the effective time, the combined company will enter into, a significant number of turnkey contracts each year. The combined company's compensation under turnkey contracts will depend on whether it successfully drills to a specified depth or, under some of the contracts, completes the well. Unlike dayrate contracts, where ultimate control is exercised by the customer, the combined company will be exposed to additional risks when serving as a turnkey drilling contractor because it makes all critical decisions. Under a turnkey contract, the amount of the combined company's compensation is fixed at the amount it bid to drill the well. Thus, the combined company will not be paid if operational problems prevent performance unless it chooses to drill a new well at its expense. Further, the combined company must absorb the loss if problems arise that cause the cost of performance to exceed the turnkey price. Given the complexities of drilling a well, it is not unusual for unforeseen problems to arise. The combined company will not generally be insured against risks of unbudgeted costs associated with turnkey drilling operations. By contrast, in a dayrate contract, the customer retains most of these risks. As a result of the additional risks the combined company will assume in performing turnkey contracts, costs incurred from time to time exceed revenues earned. Accordingly, in prior quarters, GlobalSantaFe incurred significant losses on certain of its turnkey contracts, and the combined company can expect that will continue to be the case in the future. Depending on the size of these losses, they may have a material adverse affect on the profitability of the combined company's turnkey drilling segment in a given period.

        Turnkey drilling operations are contingent on the combined company's ability to win bids and on rig availability, and the failure to win bids or obtain rigs for any reason may have a material adverse effect on the financial results of the combined company.

        The combined company's results of operations from its drilling management services segment may be limited by certain factors, including its ability to find and retain qualified personnel, to hire suitable rigs at acceptable rates, and to obtain and successfully perform turnkey drilling contracts based on competitive bids. The combined company's ability to obtain turnkey drilling contracts is largely dependent on the number of these contracts available for bid, which in turn is influenced by market prices for oil and natural gas, among other factors. Furthermore, the combined company's ability to enter into turnkey drilling contracts may be constrained from time to time by the availability of the combined company's or third-party drilling rigs. Constraints on the availability of rigs may cause delays in the combined company's drilling management projects and a reduction in the number of projects

32



that the combined company can complete overall, which could have an adverse effect on the results of operations of the combined company's drilling management services business.

        Public health threats could have a material adverse effect on the combined company's operations and its financial results.

        Public health threats, such as the bird flu, Severe Acute Respiratory Syndrome, and other highly communicable diseases, outbreaks of which have already occurred in various parts of the world in which the combined company will operate, could adversely impact the combined company's operations, the operations of clients and the global economy, including the worldwide demand for oil and natural gas and the level of demand for the combined company's services. Any quarantine of personnel or inability to access the combined company's offices or rigs could adversely affect the combined company's operations. Travel restrictions or operational problems in any part of the world in which the combined company will operate, or any reduction in the demand for drilling services caused by public health threats in the future, may materially impact operations and adversely affect the combined company's financial results.

        Compliance with or breach of environmental laws can be costly and could limit the combined company's operations.

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

        Transocean and GlobalSantaFe have generally been able to obtain some degree of contractual indemnification pursuant to which their clients agree to protect and indemnify them against liability for pollution, well and environmental damages; however, there is no assurance that the combined company can obtain such indemnities in all of its contracts or that, in the event of extensive pollution and environmental damages, its clients will have the financial capability to fulfill their contractual obligations to the combined company. Also, these indemnities may not be enforceable in all instances. In addition, the combined company may be effectively prevented from enforcing these indemnities because of the nature of its relationship with some of its larger clients.

        The combined company's ability to operate its rigs in the U.S. Gulf of Mexico could be restricted by governmental regulation.

        Hurricanes Ivan, Katrina and Rita caused damage to a number of rigs in the U.S. Gulf of Mexico fleet, and rigs that were moved off location by the storms may have damaged platforms, pipelines, wellheads and other drilling rigs during their movements. The Minerals Management Service of the U.S. Department of the Interior ("MMS") has conducted hearings and is undertaking studies to determine methods to prevent or reduce the number of such incidents in the future. The MMS issued guidelines requiring jackup drilling rigs operating in the U.S. Gulf of Mexico to operate during hurricane season with a greater air gap between the hull of the rig and the water, effectively reducing the water depth in which the rigs can operate. The regulations also require operators to conduct more

33



stringent subjective risk assessments of the soil conditions in which the rigs operate in order to increase the survivability of rigs in hurricane conditions. These regulations limit the areas in which particular jackup rigs can operate and expose operators to greater risk of a contracted rig not being able to operate at a specified location, and may reduce the marketability of certain rigs or generally decrease the demand for jackup rigs during hurricane season. In 2006, the MMS issued interim guidelines requiring that semisubmersibles operating in the U.S. Gulf of Mexico assess their mooring systems against stricter criteria. In 2007 additional guidelines were issued which impose stricter criteria, requiring rigs to meet 25-year storm conditions. Although all of the combined company's semisubmersibles currently operating in the U.S. Gulf of Mexico meet the 2007 requirements, these guidelines may negatively impact the combined company's ability to operate other of its semisubmersibles in the U.S. Gulf of Mexico in the future. Moreover, the MMS may issue additional regulations that could increase the cost of operations or reduce the area of operations for the combined company's rigs in the future, thus reducing their marketability. Implementation of additional MMS regulations may subject it to increased costs or limit the operational capabilities of its rigs and could materially and adversely affect its operations in the U.S. Gulf of Mexico.

        World political events have resulted in military action in Afghanistan and Iraq and terrorist attacks and related unrest. Military action by the United States or other nations could escalate and further acts of terrorism may occur in the U.S. or elsewhere. Such acts of terrorism could be directed against companies such as the combined company. Such developments have caused instability in the world's financial and insurance markets in the past. In addition, these developments could lead to increased volatility in prices for crude oil and natural gas and could affect the markets for drilling services. Insurance premiums could increase and coverages may be unavailable in the future.

        U.S. government regulations may effectively preclude the combined company from actively engaging in business activities in certain countries. These regulations could be amended to cover countries where Transocean and GlobalSantaFe currently operate or where the combined company may wish to operate in the future.

THE TRANSOCEAN MEETING

        Transocean is furnishing this joint proxy statement to its shareholders in connection with the solicitation of proxies by Transocean's board of directors for use at a meeting of its shareholders to consider the Reclassification, the issuance of Transocean ordinary shares in the Merger and the amendment and restatement of Transocean's memorandum of association and articles of association. Transocean is first mailing this joint proxy statement and accompanying form of proxy to its shareholders beginning on or about                        , 2007.

        The Transocean shareholders meeting is comprised of two parts held consecutively at the same location. The first part of the meeting is a vote of of Transocean shareholders convened pursuant to an order of the Grand Court of the Cayman Islands (the "Grand Court") dated                        , 2007, in respect of the Reclassification. The second part of the meeting is a general vote of Transocean shareholders convened pursuant to the provisions of Transocean's articles of association in respect of the issuance of Transocean ordinary shares in the Merger and the amendment and restatement of Transocean's memorandum of association and articles of association. The enclosed proxy card will be used at both parts of the meeting. For purposes of this joint proxy statement, references to "the Transocean meeting" or "the meeting of Transocean shareholders" and similar terms refer to actions taken at either part of the meeting.


Time, Date and Place

        The meeting of Transocean shareholders will be held on                        , 2007, at    :     [a.m./p.m.], Bahamas time, which is    :     [a.m./p.m.] Houston time, at the                        .


Purpose of the Transocean Meeting

        At the meeting, Transocean's board of directors will ask the shareholders to vote to approve:

        Transocean's board of directors has unanimously approved the Reclassification, the issuance of Transocean ordinary shares to GlobalSantaFe shareholders in the Merger, and the amendment and restatement of Transocean's memorandum of association and articles of association, and unanimously recommends that Transocean's shareholders vote "FOR" each proposal.


Record Date; Voting Rights; Vote Required for Approval

        The Transocean board has fixed the close of business on                        , 2007, as the record date for the Transocean meeting.

38



        Only holders of record of Transocean ordinary shares on the record date are entitled to notice of and to vote at the meeting.

        On the record date of the Transocean meeting, approximately                        Transocean ordinary shares were issued and entitled to be voted at the meeting. Each Transocean ordinary share entitles the holder to one vote.

        The presence, in person or by proxy, of the holders of a majority of the outstanding Transocean ordinary shares is necessary to constitute a quorum at the meeting for purposes of proposals (2) and (3) below. Abstentions, proxies returned without instructions and broker non-votes will count in the determination of shares present at the meeting for purposes of determining the presence of a quorum. There is no formal quorum requirement in respect of proposal (1).

        Assuming the presence of a quorum for purposes of proposals (2) and (3) below, the following shareholder votes are required to approve the indicated proposals at the meeting.

Proposal

  Vote "FOR" Required
(1) Reclassification of the Transocean ordinary shares   holders of a majority in number of the ordinary shares present and voting on the proposal, whether in person or by proxy, representing 75% or more in value of the ordinary shares present and voting on the proposal, whether in person or by proxy

(2)

Issuance of Transocean ordinary shares to GlobalSantaFe shareholders in the Merger

 


holders of shares representing at least a majority of votes cast on the proposal, provided that the total number of votes cast represents a majority of the votes entitled to be cast

(3)

Amendment and restatement of Transocean's memorandum of association and articles of association

 


holders of shares representing at least two-thirds of the votes cast on the proposal

        Approval of the proposals to approve the Reclassification, the issuance of Transocean ordinary shares to GlobalSantaFe shareholders in the Merger and the amendment and restatement of Transocean's memorandum of association and articles of association are conditions to the completion of the Transactions. These proposals, if approved, will be implemented only if the Transactions are completed.

        The directors and executive officers of Transocean have indicated that they intend to vote their shares in favor of all of the proposals. On the record date, directors and executive officers of Transocean and their affiliates beneficially owned less than one percent of the outstanding Transocean ordinary shares. In addition, Siem Industries, Inc., an affiliate of Kristian Siem, a director of Transocean, holds 1,423,720 ordinary shares of Transocean. Siem Industries has indicated that it intends to vote its shares in favor of all of the proposals.


Proxies

        All ordinary shares of Transocean represented by properly executed proxies received at or prior to the Transocean meeting and not revoked will be voted in accordance with the instructions indicated in those proxies.

        A properly executed proxy that is returned without instructions as to the vote desired on any or all of the proposals will be voted "FOR" each proposal. If any other matters properly come before the

39



meeting, the proxy will vote the shares represented by the enclosed proxy card in accordance with his best judgment, unless authority to do so is withheld in the proxy.

        Transocean's shareholders may abstain on any or all of the proposals, by marking "ABSTAIN" with respect to any or all of the proposals.

        Under New York Stock Exchange rules, brokers who hold shares in street name for customers have the authority to vote on "routine" proposals when they have not received instructions from beneficial owners, but are precluded from exercising their voting discretion with respect to proposals for "non-routine" matters. Proxies submitted by brokers without instructions from customers for these non-routine matters are referred to as "broker non-votes." Each of Transocean's proposals are non-routine matters under NYSE rules.

        The following table shows the effect that a proxy without instructions, an abstention or, in the case of the proposals for non-routine matters, a "broker non-vote" will have on the votes on Transocean's proposals.

 
 
  Effect on Vote
Proposal

  Proxy
Without
Instructions

  Abstention
  Broker
Non-Votes

(1) Reclassification of the Transocean ordinary shares   "FOR"   None(a)   None(a)
(2) Issuance of Transocean ordinary shares to GlobalSantaFe shareholders in the Merger   "FOR"   None(b)   None(b)
(3) Amendment and restatement of Transocean's memorandum of association and articles of association   "FOR"   None(c)   None(c)

(a)
An abstention or broker non-vote on this proposal has the effect of a vote not being cast with respect to the relevant shares in relation to the proposal. As a consequence, such shares will not be considered when determining whether the proposal has received the required approval by holders of a majority in number of the Transocean ordinary shares present and voting on the proposal, whether in person or by proxy, representing 75% or more in value of the ordinary shares present and voting on the proposal, whether in person or by proxy.

(b)
As long as holders of shares representing a majority of the outstanding ordinary shares cast votes on this proposal, an abstention or broker non-vote on this proposal will not affect the voting on the proposal because the proposal requires the consent of shareholders, present and voting, entitled to exercise a majority of the votes cast. Otherwise, the effect of an abstention or broker non-vote is a vote "AGAINST" the proposal.

(c)
An abstention or broker non-vote on this proposal has the effect of a vote not being cast with respect to the relevant shares in relation to the proposal. As a consequence, such shares will not be considered when determining whether the proposal has received the required approval by holders of shares representing two-thirds of the votes cast on the proposal.

        A share with respect to which a shareholder is present in person or by proxy but abstains or is broker non-voted will be counted toward determining whether a quorum is present.

        Transocean's shareholders may use the accompanying proxy card if they are unable or do not wish to attend the meeting in person, or if they wish to have their shares voted by proxy even though they do attend the meeting. Transocean's shareholders may revoke a proxy before it is voted by:

40


        If you do not appoint a proxy and you do not vote at the meeting, you will still be bound by the outcome. You are therefore strongly urged to attend and vote at the meeting in person or by proxy.

        Transocean and GlobalSantaFe will equally share the expenses incurred in connection with the printing and mailing of this joint proxy statement. All other costs of solicitation of proxies from holders of Transocean's ordinary shares will be paid by Transocean. In addition to solicitation by mail, Transocean will make arrangements with brokerage houses and other custodians, nominees and fiduciaries to send the proxy materials to beneficial owners, and Transocean will, upon request, reimburse those brokerage houses and custodians for their reasonable related expenses. Transocean has retained D.F. King & Co., Inc. for a fee of $17,500, plus expenses, to aid in the solicitation of proxies from Transocean shareholders and to verify certain records related to the solicitations. To the extent necessary in order to ensure sufficient representation at its meeting, Transocean or its proxy solicitor may request the return of proxy cards by personal interview, mail, telephone, facsimile, internet or other means of electronic transmission. The extent to which this will be necessary depends upon how promptly proxy cards are returned. Transocean urges its shareholders to send in their proxies without delay.

        Transocean shareholders (including any beneficial owners of such shares that give voting instructions to a custodian or clearing house that subsequently votes on proposal (1)) who vote either for or against proposal (1) should note that they are entitled to appear in person or by counsel at the Grand Court hearing on                        at which Transocean will seek the sanction of the Reclassification.

41



THE GLOBALSANTAFE MEETING

        GlobalSantaFe is furnishing this joint proxy statement to its shareholders in connection with the solicitation of proxies by GlobalSantaFe's board of directors for use at a meeting of its shareholders to consider the Merger. GlobalSantaFe is first mailing this joint proxy statement and accompanying form of proxy to its shareholders beginning on or about                         , 2007.

        The GlobalSantaFe shareholders meeting is comprised of two parts held consecutively at the same location. The first part of the meeting is comprised of a vote of the GlobalSantaFe's shareholders convened pursuant to an order of the Grand Court dated                        , 2007, in respect of the Merger (the "GlobalSantaFe court-mandated vote"). Under Cayman Islands law, such a court-mandated vote is required in order to approve a scheme of arrangement such as the Merger. In addition, because GlobalSantaFe's articles of association require the separate approval of an amalgamation, such as the Merger, by GlobalSantaFe's shareholders, there will be another vote taken during the second part of the meeting to approve the Merger, which vote will be conducted in accordance with the requirements of an extraordinary general meeting of GlobalSantaFe shareholders under GlobalSantaFe's articles of association (the "GlobalSantaFe general vote"). Under Cayman Islands law, GlobalSantaFe must hold two separate votes on the proposal as described below. The enclosed proxy card will be used at both parts of the meeting. For purposes of this joint proxy statement, references to "the GlobalSantaFe meeting", "the meeting of GlobalSantaFe shareholders" or similar terms refer to actions taken at either the GlobalSantaFe court-mandated vote or the GlobalSantaFe general vote unless the context requires otherwise.


Time, Date and Place

        The meeting of GlobalSantaFe's shareholders will be held on                        , 2007, at    :     [a.m/p.m.], Houston time, at the                        .


Purpose of the GlobalSantaFe Meeting

        During each part of the meeting, GlobalSantaFe's board of directors will ask its shareholders to vote to approve:

        GlobalSantaFe's board of directors has unanimously (with one director absent) approved the Merger and recommends that GlobalSantaFe's shareholders vote "FOR" the proposal.


Record Date; Voting Rights; Vote Required for Approval

        GlobalSantaFe has fixed the close of business on                        , 2007, as the record date for the GlobalSantaFe meeting.

        Only holders of record of GlobalSantaFe ordinary shares on the record date are entitled to notice of and to vote at the GlobalSantaFe meeting.

42



        On the record date, approximately                        GlobalSantaFe ordinary shares were issued and entitled to be voted at the GlobalSantaFe meeting. Each GlobalSantaFe ordinary share entitles the holder to one vote.

        There is no formal quorum requirement in respect of the approval of the proposal in connection with the GlobalSantaFe court-mandated vote. The presence, in person or by proxy, of the holders of a majority of the outstanding GlobalSantaFe ordinary shares is necessary to constitute a quorum for purposes of the GlobalSantaFe general vote. Abstentions, proxies returned without instructions and broker non-votes will count in the determination of shares present at the GlobalSantaFe meeting for purposes of determining the presence of a quorum with respect to the GlobalSantaFe general vote.

        Assuming the presence of a quorum for purposes of the GlobalSantaFe general vote, the following votes are required to approve the proposal at the indicated part of the GlobalSantaFe meeting:

Part of Meeting

  Vote "FOR" Required
(1) First part—court-mandated vote   holders of a majority in number of the ordinary shares present and voting on the proposal, whether in person or by proxy, representing 75% or more in value of the ordinary shares present and voting on the proposal, whether in person or by proxy

(2)

Second part—general vote

 


holders of shares representing at least a majority of votes cast on the proposal

        Approval of the proposal at both parts of the meeting is a condition to the completion of the Transactions, including the Merger.

        In connection with the GlobalSantaFe general vote, the vote of each joint holder of record, whether in person or by proxy, is required in order for such joint holder's vote to be counted. In connection with the GlobalSantaFe court-mandated vote, the vote of each joint holder of record, whether in person or by proxy, will be sufficient for such joint holder's vote to be counted.

        The directors and executive officers of GlobalSantaFe have indicated that they intend to vote their shares in favor of the proposal. On the record date, directors and executive officers of GlobalSantaFe and their affiliates beneficially owned less than one percent of the outstanding GlobalSantaFe ordinary shares.


Proxies

        All ordinary shares of GlobalSantaFe represented by properly executed proxies received at or prior to the commencement of the GlobalSantaFe meeting and not revoked will be voted in accordance with the instructions indicated in those proxies.

        A properly executed proxy that is returned without instructions as to the vote desired on any or all of the proposals will be voted "FOR" the proposal at each part of the GlobalSantaFe meeting. If any other matters properly come before the meeting, the proxy will vote the shares represented by the enclosed proxy card in accordance with his best judgment, unless authority to do so is withheld in the proxy.

        GlobalSantaFe's shareholders may abstain with respect to the proposal by marking "ABSTAIN".

        Under New York Stock Exchange rules, brokers who hold shares in street name for customers have the authority to vote on "routine" proposals when they have not received instructions from beneficial owners, but are precluded from exercising their voting discretion with respect to proposals for "non-routine" matters. Proxies submitted by brokers without instructions from customers for these

43



non-routine matters are referred to as "broker non-votes." The GlobalSantaFe proposal is a non-routine matter under NYSE rules.

        The following table shows the effect that a proxy without instructions, an abstention or, in the case of the proposals for non-routine matters, a "broker non-vote" will have on the votes on the GlobalSantaFe proposal at each part of the GlobalSantaFe meeting:

 
   
  Effect on Vote
 
  Part of Meeting

  Proxy Without Instructions
  Abstention
  Broker
Non-Votes

(1)   First part—court-mandated vote   "FOR"   None(a)   None(a)
(2)   Second part—general vote   "FOR"   None(b)   None(b)

(a)
For purposes of the GlobalSantaFe court-mandated vote, an abstention or broker non-vote on the proposal has the effect of a vote not being cast with respect to the relevant shares in relation to the proposal. As a consequence, such shares will not be considered when determining whether the proposal has received the required approval by holders of a majority in number of the GlobalSantaFe ordinary shares present and voting on the proposal, whether in person or by proxy, representing 75% or more in value of the ordinary shares present and voting on the proposal, whether in person or by proxy.

(b)
For purposes of the GlobalSantaFe general vote, as long as holders of shares representing a majority of the outstanding ordinary shares are present and a majority of those shares present are voted in favor of this proposal, an abstention or broker non-vote on the proposal will not affect the voting on the proposal because the proposal requires the consent of GlobalSantaFe shareholders, present and voting, representing a majority of the votes cast. Otherwise, the effect of an abstention or broker non-vote is a vote "AGAINST" the proposal.

        A share with respect to which a shareholder is present in person or by proxy but abstains or is broker non-voted will be counted toward determining whether a quorum is present for purposes of the GlobalSantaFe general vote.

        GlobalSantaFe's shareholders may use the accompanying proxy card if they are unable or do not wish to attend the meeting in person, or if they wish to have their shares voted by proxy even though they do attend the meeting. GlobalSantaFe's shareholders may revoke a proxy before it is voted by:

        If you do not appoint a proxy and you do not vote at the meeting, you will still be bound by the outcome. You are therefore strongly urged to attend and vote at the meeting in person or by proxy.

        Transocean and GlobalSantaFe will equally share the expenses incurred in connection with the printing and mailing of this joint proxy statement. All other costs of solicitation of proxies from holders of GlobalSantaFe's ordinary shares will be paid by GlobalSantaFe. In addition to solicitation by mail, GlobalSantaFe will make arrangements with brokerage houses and other custodians, nominees and fiduciaries to send the proxy materials to beneficial owners, and GlobalSantaFe will, upon request, reimburse those brokerage houses and custodians for their reasonable related expenses. GlobalSantaFe has retained Georegeson Inc. for a fee of $15,000, plus expenses, to aid in the solicitation of proxies from GlobalSantaFe shareholders and to verify certain records related to the solicitations. To the extent necessary in order to ensure sufficient representation at its meeting, GlobalSantaFe or its proxy solicitor may request the return of proxy cards by personal interview, mail, telephone, facsimile, internet or other means of electronic transmission. The extent to which this will be necessary depends

44



upon how promptly proxy cards are returned. GlobalSantaFe urges its shareholders to send in their proxies without delay.

        GlobalSantaFe shareholders (including any beneficial owners of such shares that give voting instructions to a custodian or clearing house that subsequently votes at the GlobalSantaFe court-mandated vote) who vote either for or against the proposal during the GlobalSantaFe court-mandated vote should note that they are entitled to appear in person or by counsel at the Grand Court hearing on            at which GlobalSantaFe will seek the sanction of the Merger.

45



THE TRANSACTIONS

Background of the Merger

        From time to time, the senior management of each of Transocean and GlobalSantaFe has engaged in preliminary discussions with other industry participants regarding the possibility of various business combination transactions. These discussions have been regularly reported to the boards of directors of Transocean and GlobalSantaFe, respectively. The boards of directors and management of Transocean and GlobalSantaFe have also from time to time reviewed possible strategic alternatives, including opportunities with other offshore drilling contractors, with the objective of further enhancing value for their respective shareholders.

        During 2005 and early 2006, Robert L. Long, the Chief Executive Officer of Transocean, and Jon A. Marshall, the President and Chief Executive Officer of GlobalSantaFe, discussed the possibility of various transactions involving the two companies, including the dispositions of certain drilling units from each company to the other company and a potential all stock business combination between the two companies. The parties decided not to pursue a business combination between the two companies at the time, primarily due to the inability of the parties to agree on financial terms of the transaction.

        During the summer of 2006, Messrs. Long and Marshall discussed their views regarding a potential business combination of the two companies; however, the parties were unable to agree on financial terms of the transaction and terminated discussions in early August 2006.

        From time to time until late September 2006, Mr. Marshall held several discussions with the chief executive officer of another offshore drilling company, referred to herein as Company A, regarding the possibility of a business combination between GlobalSantaFe and Company A.

        On September 15, 2006, Mr. Marshall renewed the dialogue with Mr. Long regarding the possibility of a business combination of the two companies and discussed possible management personnel and board representation of a combined company.

        On October 4, 2006, Mr. Long and Mr. Marshall met to discuss the potential business combination, including possible financial terms, the potential form of consideration to be paid (i.e., cash, Transocean ordinary shares or a combination thereof) and management of the combined company.

        On October 12, 2006, Transocean's management discussed these matters with the Transocean board of directors, which instructed management to further analyze a possible transaction. Following the board meeting, representatives of Transocean consulted with Goldman Sachs regarding an analysis of a potential combination of the two companies.

        In late October 2006, another offshore drilling company, referred to herein as Company B, delivered to GlobalSantaFe a letter which indicated an interest in engaging in a business combination transaction. Thereafter, senior management of GlobalSantaFe had several conversations with senior management of Company B regarding the possibility of combining the companies.

        In November 2006, the board of directors of GlobalSantaFe empowered the Nominating and Governance Committee to work with management in exploring the possibility of a sale of GlobalSantaFe to a private equity firm. The committee authorized members of senior management to hold preliminary discussions with two private equity groups. These discussions did not result in an offer from either private equity group. Also in November 2006, GlobalSantaFe engaged Lehman Brothers to advise the GlobalSantaFe board of directors with respect to an analysis of strategic alternatives.

        On December 6, 2006, Transocean formally engaged Goldman Sachs as its financial advisor in connection with a possible business combination with GlobalSantaFe.

46



        At a meeting of the board of directors of GlobalSantaFe held on December 7, 2006, GlobalSantaFe's senior management and Lehman Brothers reviewed with the board of directors of GlobalSantaFe various potential strategic alternatives, including possible business combinations with several competitors, including Transocean, a recapitalization and potential asset acquisitions.

        On December 7, 2006, at a Transocean board of directors meeting, management reviewed a potential business combination with GlobalSantaFe. The board discussed the potential combination and determined that the financial terms of the combination at the time were not compelling and concluded no transaction should be pursued at that time. Following the meeting, Mr. Long informed Mr. Marshall of the Transocean board's decision.

        In early February 2007, members of senior management of Company B again expressed to Mr. Marshall Company B's interest in acquiring GlobalSantaFe. Mr. Marshall advised Company B that he was not in a position to engage in discussions unless an acquisition proposal was made to GlobalSantaFe. Company B failed to make such an offer.

        Later in February of 2007, Mr. Marshall met with the chief executive officer of Company A to gauge Company A's interest in a business combination between the companies. The chief executive officer of Company A informed Mr. Marshall that the board of directors of Company A was not interested in pursuing a transaction.

        On February 26, 2007, GlobalSantaFe engaged Lehman Brothers in connection with the review by GlobalSantaFe of a business combination with Transocean. Thereafter, Lehman Brothers performed various financial analyses of a potential combination of Transocean and GlobalSantaFe under various structures and scenarios, including a possible GlobalSantaFe proposal to acquire Transocean.

        Subsequently, at the regularly scheduled March 2007 meeting of the board of directors of GlobalSantaFe, Mr. Marshall updated the board of directors of GlobalSantaFe on the discussions he had held since the last board meeting. In addition, management reviewed with the board the prospect of a leveraged acquisition of Transocean. Management also discussed further with the board the possibility of a leveraged recapitalization of GlobalSantaFe. Following the March 2007 board meeting, senior management of GlobalSantaFe, together with Skadden, Arps, Slate, Meagher & Flom LLP, GlobalSantaFe's outside counsel, and Lehman Brothers, continued to analyze a possible leveraged acquisition of Transocean.

        On March 21, 2007, Mr. Marshall again met with the chief executive officer of Company A, who reiterated that the board of directors of Company A was not interested in a transaction with GlobalSantaFe.

        On March 23, 2007, Messrs. Long and Marshall met and Mr. Marshall suggested that GlobalSantaFe was considering a proposal to acquire Transocean. Messrs. Long and Marshall also discussed other possible transaction scenarios, including a "merger of equals" stock transaction and an acquisition of GlobalSantaFe by Transocean.

        On March 29, 2007, Messrs. Long and Marshall met and Mr. Marshall asked if Transocean would be receptive to a cash offer by GlobalSantaFe to acquire Transocean. Mr. Long responded that if GlobalSantaFe made an offer, he would present it for consideration by the Transocean board at the regularly scheduled May 2007 board meeting.

        During April 2007, the senior management of GlobalSantaFe, together with Skadden and Lehman Brothers, continued to review the parameters of an offer for Transocean.

        Also during April 2007, Goldman Sachs began work on a financial analysis of a potential combination of Transocean and GlobalSantaFe under various structures and scenarios, including a possible GlobalSantaFe proposal to acquire Transocean. Transocean also consulted with Baker Botts L.L.P., Transocean's legal counsel, as to legal aspects relating to those matters.

47



        On May 1, 2007, the board of directors of GlobalSantaFe held a special meeting to review a possible acquisition of Transocean. At the meeting, Lehman Brothers reviewed the financial aspects of an acquisition of Transocean with the GlobalSantaFe board of directors, and representatives of Skadden reviewed with the board certain legal aspects of such an acquisition. Lehman Brothers also advised the GlobalSantaFe board with respect to the ability of GlobalSantaFe to obtain financing for an acquisition of Transocean. The GlobalSantaFe board authorized a proposal by GlobalSantaFe to acquire Transocean for $106 per share in cash.

        On May 7, 2007, at a meeting between Messrs. Long and Marshall, Mr. Robert Rose, Chairman of the Board of Directors of GlobalSantaFe, and Mr. J. Michael Talbert, Chairman of the Board of Directors of Transocean, GlobalSantaFe delivered a letter by which GlobalSantaFe proposed to acquire Transocean in an all cash transaction at a price of $106 per Transocean ordinary share, with the possibility of an equity component of the consideration representing up to 25% of the total consideration. The letter indicated a willingness to discuss Transocean's management contribution to, board representation for and the name of the combined company. At that time, the parties discussed the merits of a merger of equals transaction.

        On the same day, following that meeting, Mr. Long and other representatives of Transocean met with representatives of Goldman Sachs and Baker Botts at Goldman Sachs' offices to discuss GlobalSantaFe's proposal. At this meeting, Goldman Sachs discussed both GlobalSantaFe's proposal and the possibility of a stock and cash merger transaction that involved significant borrowing by the combined company.

        On May 10, 2007, Transocean's board of directors met and considered GlobalSantaFe's proposal. At the meeting, Goldman Sachs reviewed the financial aspects of the GlobalSantaFe proposal to acquire Transocean with Transocean's board of directors and representatives of Baker Botts and Walkers, Transocean's Cayman Islands legal counsel, advised the board regarding its fiduciary duties. Goldman Sachs also reviewed with the Transocean board other combination structures, including the possible stock and cash merger transaction that would return cash to Transocean shareholders. After discussion and consultation with its legal and financial advisors, the board determined not to pursue the proposal, and concluded that Transocean shareholders would be better served by Transocean instead continuing to pursue its strategic plan as an independent company.

        On May 12, 2007, Mr. Long responded to GlobalSantaFe's May 7, 2007 letter. He indicated that Transocean's board of directors had determined not to pursue the GlobalSantaFe proposal. Nevertheless, Mr. Long indicated that a combination of the two companies could provide significant strategic benefit and the potential for the creation of increased value for shareholders. During the conversation, Mr. Marshall suggested the possibility of a transaction structured as a merger of equals and noted that he thought such a transaction was achievable.

        On May 17, 2007, Mr. Long updated certain members of the Transocean board of directors regarding the potential business combination with GlobalSantaFe.

        On May 20, 2007, Messrs. Long and Talbert met with Messrs. Marshall and Rose. Messrs. Long and Talbert responded to Mr. Marshall's suggestion of a possible merger of equals transaction and indicated that Transocean's board of directors might consider such a transaction with an exchange ratio based on current market prices for each company's ordinary shares if each company's shareholders also received proportionate cash consideration funded by approximately $15 billion of borrowings. The parties also discussed the management and board of directors of the combined company, including management succession issues.

        On a May 21, 2007 board conference call, Mr. Long informed the Transocean board of directors of the prior day's meeting with the GlobalSantaFe representatives.

        On May 22, 2007, Transocean instructed Baker Botts to begin preparing a draft merger agreement.

48



        On May 25, 2007, Messrs. Long and Marshall met to discuss board representation and senior management positions of the combined company.

        Beginning the week of May 28, 2007, representatives of Goldman Sachs and representatives of Transocean had discussions regarding the possibility of affiliates of Goldman Sachs providing the financing required for the cash portion of the transaction. These discussions were subsequently extended to include GlobalSantaFe and Lehman Brothers as to the possibility of affiliates of Lehman Brothers also providing a portion of such required financing.

        On June 5, 2007, Messrs. Long and Marshall discussed by telephone potential board positions, board committee composition and the process for determining the market prices of each company's ordinary shares for purposes of establishing an exchange ratio based on those prices and whether the board of the combined company would have a vice chairman.

        In early June, Mr. Marshall again met with members of senior management of Company B. At that meeting, the Company B representatives informed Mr. Marshall that Company B was not interested in acquiring GlobalSantaFe, but would be willing to consider a sale of Company B to GlobalSantaFe.

        Subsequently, at the regularly scheduled June 2007 meeting of the board of directors of GlobalSantaFe, management, Skadden and Lehman Brothers updated the board of directors of GlobalSantaFe on the status of discussions with Transocean, as well as the opportunity to acquire Company B. In light of the GlobalSantaFe board's view of the greater benefits of the contemplated transaction with Transocean, GlobalSantaFe determined not to pursue an acquisition of Company B.

        On June 8, 2007, Messrs. Long and Marshall met and discussed representation on the combined company's board of directors, committee chairs, chairman and vice chairman of the board, management succession issues and the anticipated amount of a termination fee for the transaction. The parties were not able to reach agreement on these issues.

        On June 9, 2007, Messrs. Long and Marshall discussed these outstanding issues by telephone, but were again unable to reach a resolution.

        On June 21, 2007, Messrs. Long, Marshall, Talbert and Rose met to discuss and try to resolve the outstanding issues. During the meeting, they agreed to recommend to their respective boards of directors: (1) the exchange ratio would not include any premium and would be based on the closing price of each company's shares on the last trading day prior to signing the merger agreement, (2) Mr. Rose would serve as chairman of the board of the combined company, (3) Mr. Long would serve as Chief Executive Officer and Mr. Marshall would serve as President and Chief Operating Officer and (4) each company would have an equal number of board members and the right to designate a chairman for two of the four committees of the board of the combined company. During the meeting, they also confirmed the prior agreements to recommend to their respective board of directors, (a) the transaction would include at least a $15 billion aggregate cash payment to the companies' shareholders, (b) the name of the combined company would be Transocean Inc., (c) the corporate policies and procedures of Transocean immediately prior to the transaction would be the corporate policies and procedures of the combined company and (d) the corporate headquarters of Transocean would be the corporate headquarters of the combined company.

        On June 23, 2007, Baker Botts delivered a draft merger agreement and confidentiality and standstill agreement to GlobalSantaFe.

        On June 25, 2007, representatives of Skadden and Baker Botts discussed the terms of the confidentiality and standstill agreement.

        On June 26, 2007, representatives of Transocean and GlobalSantaFe and their respective financial and legal advisors met at the offices of Baker Botts and discussed the principal transaction terms,

49



possible structures of the transaction, anticipated financing of the cash payment in the transaction, the process for each company to conduct due diligence and the anticipated process and timing for completing the transaction. During that meeting, the parties entered into a mutual confidentiality and standstill agreement. The parties set a target of July 21, 2007 as a possible date to execute a definitive merger agreement.

        On June 27, 2007, the board of directors of GlobalSantaFe held a special meeting, at which Mr. Marshall provided an update regarding the discussions with Transocean. From June 27, 2007, through July 21, 2007, representatives of GlobalSantaFe and Transocean and their respective legal and financial advisors negotiated the terms of the merger agreement, exchanged due diligence materials and met several times to discuss due diligence and financing matters.

        On July 20, 2007, the closing price of Transocean's ordinary shares was $109.97, and the closing price of GlobalSantaFe's ordinary shares was $74.74. Following the close of trading on that day, Mr. Long and Mr. Marshall agreed to recommend to their respective board of directors that in connection with the proposed Transactions each Transocean ordinary share be reclassified into 0.6996 Transocean ordinary shares and $33.03 in cash and each GlobalSantaFe ordinary share be exchanged in the Merger for 0.4757 Transocean ordinary shares and $22.46 in cash.

        On July 21, 2007, Transocean's board of directors met to consider the proposed Transactions. Transocean's management reviewed the strategic rationale and the anticipated benefits of the transaction to Transocean's shareholders, and presented an overview of the structure, terms and effects of the Transactions. Transocean's management also reviewed certain financial aspects of the Transactions and the results of the due diligence process. Representatives of Goldman Sachs reviewed with Transocean's board of directors the financial terms of the Transactions and presented certain financial analyses conducted with respect to the Transactions. Goldman Sachs then delivered its oral opinion (which was subsequently confirmed in writing) to the effect that, as of the date of the opinion and based upon and subject to the factors and assumptions set forth in the opinion, and after taking into account the Reclassification, in the aggregate the 0.4757 Transocean ordinary shares and the $22.46 in cash to be paid by Transocean in respect of each GlobalSantaFe ordinary share pursuant to the merger agreement was fair from a financial point of view to Transocean (see "—Opinion of Goldman, Sachs & Co."). Baker Botts and Walkers, Transocean's legal advisors, reviewed the terms of the proposed merger agreement and the fiduciary obligations of the board of directors relating to the transaction. Transocean's board unanimously approved the merger agreement and related amendments to the Transocean memorandum of association and articles of association and authorized the officers to enter into the merger agreement and related transactions.

        On July 21, 2007, the board of directors of GlobalSantaFe held a special meeting to consider further the strategic business combination between GlobalSantaFe and Transocean. At the meeting, GlobalSantaFe's management updated the board on the terms of the proposed transaction and the results of the due diligence process, and reviewed the strategic rationale and the anticipated benefits of the transaction to GlobalSantaFe's shareholders; and representatives of Skadden reviewed the terms of the proposed merger agreement and the fiduciary obligations of the board of directors when considering a strategic business combination with Transocean. Representatives of Lehman Brothers reviewed the financial terms of the Transactions and presented certain financial analyses conducted with respect to the Transactions, and each of Lehman Brothers and Simmons & Company rendered an oral opinion (as subsequently confirmed in writing in opinions dated July 21, 2007), that as of that date and based on and subject to the assumptions made, procedures followed, matters considered and limitations of review set forth in their respective opinions, the aggregate merger consideration to be received by GlobalSantaFe stockholders in the merger was fair from a financial point of view to such stockholders (see "—Opinion of Lehman Brothers Inc." and "—Opinion of Simmons & Company International"). Following discussions, the board of directors of GlobalSantaFe unanimously (with one director absent) approved the merger agreement, the merger, the other transactions contemplated by the merger

50



agreement and resolved to recommend the approval and adoption by GlobalSantaFe's stockholders of the merger agreement.

        Following the board meetings, the merger agreement was finalized and on July 21, 2007, the parties signed the merger agreement. Both parties also signed the bridge loan facility commitment letters with affiliates of Goldman Sachs and Lehman Brothers. On July 23, 2007, Transocean and GlobalSantaFe issued press releases announcing the execution of the merger agreement.


Transocean's Reasons for the Transactions

        The Transocean board of directors believes that the Transactions will create value for its shareholders, expand and enhance the combined company's offshore drilling fleet and thus better position the combined company to address the growing and more technically challenging needs of its customers on a global basis, provide its customers with consistently high-quality service in all key offshore drilling areas of the world and create opportunities for its employees. At the same time, the Transactions will allow Transocean shareholders to receive $33.03 in cash for each Transocean ordinary share they own.

        In reaching its conclusion to approve the Transactions and recommend that Transocean's shareholders vote "FOR" the proposals, Transocean's board of directors consulted with members of management and its financial and legal advisors and considered many factors, including the following:

        The Transocean board of directors considered a number of factors pertaining to the strategic rationale for the Transactions as generally supporting its decision to enter into the merger agreement, including the following:

Based on the due diligence process, the Transocean board determined that these risks were manageable as part of the ongoing business of the combined company.

        In determining that the Transactions were advisable and in the best interests of Transocean's shareholders, the board of directors of Transocean considered the enumerated factors as a whole and did not quantify or otherwise assign relative weights to the different factors. The Transocean board of directors views its recommendation as being based on the totality of the information presented to and considered by it. Individual directors may have given different weights to different factors. Moreover, the foregoing discussion of the reasons for the Transactions is not intended to be exhaustive.

        For the reasons discussed, Transocean's board of directors has determined that the merger agreement and the transactions contemplated by the merger agreement are advisable and in the best interests of Transocean and its shareholders, has unanimously approved the merger agreement and the transactions contemplated by the merger agreement, and recommends that shareholders vote "FOR" approval of the Reclassification, the issuance of ordinary shares to the shareholders of GlobalSantaFe in the Merger and the amendment and restatement of Transocean's memorandum of association and articles of association.


GlobalSantaFe's Reasons for the Transactions

        The board of directors of GlobalSantaFe believes that the expanded and enhanced drilling fleets of the combined company will better position it to address the growing and more technically challenging needs of its customers on a global basis and provide its customers with consistently high quality service in all key drilling areas of the world. The GlobalSantaFe board of directors believes that the combined company will be a premier worldwide contract driller with the breadth and depth necessary to compete in today's international oil and natural gas drilling marketplace.

Recommendation of GlobalSantaFe's Board of Directors

        GlobalSantaFe's board of directors has unanimously determined (with one director absent) that the merger agreement and the transactions contemplated thereby are advisable and are fair to, and in the best interests of, GlobalSantaFe and its shareholders, and recommends that its shareholders vote "FOR" the proposals.


Opinion of Goldman, Sachs & Co.

        Transocean retained Goldman Sachs as its financial advisor in connection with the Merger.

        In this capacity Goldman Sachs rendered its opinion to Transocean's board of directors that, as of July 21, 2007, and based upon and subject to the factors and assumptions set forth therein, and after taking into consideration the Reclassification, in the aggregate the 0.4757 Transocean ordinary shares and the $22.46 in cash to be paid by Transocean in respect of each GlobalSantaFe ordinary share pursuant to the merger agreement was fair from a financial point of view to Transocean.

        The full text of the written opinion of Goldman Sachs, dated July 21, 2007, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex B and is incorporated by reference in this joint proxy statement. You should read the opinion in its entirety. Goldman Sachs provided its opinion for the information and assistance of Transocean's board of directors in connection with its consideration of the transactions contemplated by the merger agreement. The Goldman Sachs opinion is not a recommendation as to how any holder of Transocean ordinary shares should vote with respect to the Merger, the Reclassification or any other matter.

        In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

58


        Goldman Sachs also held discussions with members of the senior management of Transocean and GlobalSantaFe regarding their assessment of the strategic rationale for, and the potential benefits of, the Merger and the past and current business operations, financial condition and future prospects of their respective companies. In addition, Goldman Sachs:

        Goldman Sachs relied upon and assumed, without assuming any responsibility for independent verification, the accuracy and completeness of all of the financial, accounting, legal, tax and other information provided to, discussed with or reviewed by it. In that regard, Goldman Sachs assumed with Transocean's consent that the Forecasts, including the Synergies, had been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Transocean. In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of Transocean or GlobalSantaFe or any of their respective subsidiaries and Goldman Sachs was not furnished with any such evaluation or appraisal. Goldman Sachs also assumed that all governmental, regulatory or other consents or approvals necessary for the consummation of the Merger will be obtained without any adverse effect on Transocean or GlobalSantaFe or on the expected benefits of the Merger in any way meaningful to its analysis. Goldman Sachs' opinion did not address any legal, regulatory, tax or accounting matters.

        Goldman Sachs' opinion did not address the underlying business decision of Transocean to engage in the Transactions, or the relative merits of the Merger as compared to any strategic alternatives that may be available to Transocean, nor did Goldman Sachs express any opinion as to the Reclassification or the prices at which Transocean ordinary shares will trade at any time. Goldman Sachs' opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to it as of, the date of the opinion and Goldman Sachs assumed no responsibility for updating, revising or reaffirming its opinion based on circumstances, developments or events occurring after the date of the opinion.

        The following is a summary of the material financial analyses delivered by Goldman Sachs to the board of directors of Transocean in connection with rendering the opinion described above. The following summary, however, does not purport to be a complete description of the financial analyses performed by Goldman Sachs, nor does the order of analyses described represent relative importance or weight given to those analyses by Goldman Sachs. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are alone not a complete description of Goldman Sachs' financial analyses. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before July 20, 2007, and is not necessarily indicative of current market conditions.

        Selected Companies Analysis.    Goldman Sachs reviewed and compared certain financial information for Transocean and GlobalSantaFe to corresponding financial information, ratios and public market multiples for the following publicly traded corporations in the offshore drilling industry:

Each of these companies is referred to as a "Selected Company."

        Although none of the Selected Companies is directly comparable to Transocean or GlobalSantaFe, the companies included were chosen because they are publicly traded companies with operations that for purposes of analysis may be considered similar to certain operations of Transocean and GlobalSantaFe.

        Goldman Sachs calculated and compared various financial multiples and ratios for the Selected Companies, Transocean and GlobalSantaFe based on information that it obtained from public filings and estimates from the Institutional Brokers Estimate System, or IBES, with respect to the Selected Companies, Transocean and GlobalSantaFe:

        Relative Discounted Cash Flow Analysis.    Goldman Sachs performed an illustrative relative discounted cash flow analysis to determine the implied exchange ratio of GlobalSantaFe ordinary shares to Transocean ordinary shares, assuming each company continued to operate as a standalone company, using the Base Case, Upside Case and Downside Case estimates for Transocean and GlobalSantaFe prepared by Transocean's management.

        In its analysis Goldman Sachs applied a range of discount rates ranging from 7% to 11% to the cash flows generated by Transocean's and GlobalSantaFe's assets over their estimated remaining lives. The illustrative discounted cash flow analysis as of December 31, 2007, did not give effect to the impact of any synergies as a result of the Merger. The following table presents the results of this analysis:

Implied Exchange Ratio

 
  Discount Rate
 
 
  7.0%

Downside Case   0.75 x 0.75 x 0.76 x 0.77 x 0.77 x

        Goldman Sachs also calculated implied exchange ratios of GlobalSantaFe ordinary shares to Transocean ordinary shares using present values of estimated cash flows for Transocean and GlobalSantaFe through the year 2011 and present values of an illustrative terminal value of Transocean and GlobalSantaFe at the end of year 2011, based on a range of multiples from 4.0x to 12.0x estimated 2012 EBITDA, and assuming a discount rate of 9%. The illustrative discounted cash flow analysis as of

Downside Case   0.77 x 0.74 x 0.72 x 0.71 x 0.69 x

        Goldman Sachs then calculated implied exchange ratios of GlobalSantaFe ordinary shares to Transocean ordinary shares using present values of estimated cash flows for Transocean and GlobalSantaFe through the year 2011 and the present value of an illustrative terminal value of Transocean and GlobalSantaFe at the end of year 2011, based on a range of multiples from 4.0x to 12.0x estimated normalized adjusted EBITDA, and a discount rate of 9%. Estimated normalized adjusted EBITDA is based on the operating assumptions for 2016 applied to the projected fleet operating during 2011. The illustrative discounted cash flow analysis as of December 31, 2007, did not give effect to the impact of any synergies as a result of the Merger.

        Reclassification Consideration vs. Standalone Discounted Cash Flow Analysis.    Based on the Base Case, the Upside Case and the Downside Case, Goldman Sachs performed an illustrative premium / (discount) analysis of the aggregate of (a) an illustrative discounted cash flow value as of December 31, 2007, of the Transocean ordinary shares (assuming consummation of the Transactions) and (b) cash being received by Transocean shareholders in the Reclassification (which aggregate we call the "Transocean reclassification consideration") in relation to an illustrative standalone discounted cash flow analysis for Transocean ordinary shares assuming there were no Transactions to determine an implied premium or discount to the holders of Transocean ordinary shares as a result of the Transactions.

        Goldman Sachs calculated ratios of Transocean reclassification consideration to the standalone illustrative discounted cash flow analysis, as of December 31, 2007, based on discount rates ranging from 7% to 11% applied to the cash flows generated by Transocean's and GlobalSantaFe's assets over their estimated remaining lives. The following table presents the results of this analysis:

Premium/(Discount) to Standalone Discounted Cash Flows

Downside Case   10.3 % 10.2 % 10.1 % 10.1 % 10.1 %

        Goldman Sachs then calculated, for each of the Base Case, the Upside Case and the Downside case, ratios of the Transocean reclassification consideration to the standalone discounted cash flow analysis, as of December 31, 2007, using present values of estimated cash flows for Transocean and GlobalSantaFe through the year 2011 and present values of an illustrative terminal value of Transocean and GlobalSantaFe at the end of year 2011, based on a range of multiples from 4.0x to 12.0x estimated 2012 EBITDA, and a discount rate of 9%. The following table presents the results of this analysis:

Downside Case   7.8 % 6.8 % 6.0 % 5.4 % 5.0 %

        Goldman Sachs then calculated for each of the Base Case, the Upside Case and the Downside case ratios of the Transocean reclassification consideration to the standalone discounted cash flow analysis, as of December 31, 2007, using present values of estimated cash flows for Transocean and GlobalSantaFe through the year 2011 and present values of an illustrative terminal value of Transocean and GlobalSantaFe at the end of year 2011, based on a range of multiples from 4.0x to 12.0x estimated normalized adjusted EBITDA, and a discount rate of 9%.

        Accretion/Dilution Analysis.    Goldman Sachs analyzed the pro forma financial effects of the Transactions on Transocean's estimated earnings per share and cash flow per share using estimates for Transocean and GlobalSantaFe based on the views of Transocean's management and assuming the Transactions closed on December 31, 2007. For each of the Base Case, Upside Case and Downside Case, Goldman Sachs compared the projected earnings per share and cash flow per share of Transocean ordinary shares on a standalone basis for 2008 and 2009, assuming no Merger or Reclassification, to the projected earnings per share and cash flow per share of the combined company assuming completion of the Transactions. This analysis indicated that the Transactions would be accretive to Transocean's shareholders on an estimated earnings per share basis and on an estimated

64



cash flow per share basis for both years analyzed.(1) The following table summarizes the results of this analysis:

Transocean notes that if standalone 2008 and 2009 estimated earnings per share are adjusted to reflect the reverse stock split in a similar fashion to how historical earnings per share will be adjusted for U.S. GAAP, then, although the Merger by itself is accretive, the Transactions in the aggregate would be dilutive to earnings and cash flow per share. For additional discussions of issues related to accretion and dilution, see "—Accounting Treatment and Considerations" and "—Accretion and Dilution Considerations."

        The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs' opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to Transocean or the Transactions.

        Goldman Sachs prepared these analyses for purposes of Goldman Sachs' providing its opinion to Transocean's board of directors as to the fairness from a financial point of view to Transocean of the aggregate consideration to be received by the holders of outstanding GlobalSantaFe ordinary shares in connection with the Merger, after taking into account the Reclassification. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of Transocean or Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecast.

        The Merger consideration to be received by GlobalSantaFe shareholders was determined through arms' length negotiations between Transocean and GlobalSantaFe and was approved by Transocean's board of directors. Goldman Sachs provided advice to Transocean during these negotiations. Goldman Sachs did not, however, recommend any specific amount of consideration to Transocean or its board of directors or that any specific amount of consideration constituted the only appropriate consideration for the Merger.

        As described above, Goldman Sachs' opinion to Transocean's board of directors was one of many factors taken into consideration by Transocean's board of directors in making its determination to approve the merger agreement. The foregoing summary does not purport to be a complete description of the analyses performed by Goldman Sachs in connection with the fairness opinion and is qualified in its entirety by reference to the written opinion of Goldman Sachs attached as Annex B.

        Goldman Sachs and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. Goldman Sachs Credit Partners L.P. ("GSCP"), an affiliate of Goldman Sachs, has committed to provide $10 billion in bridge financing to Transocean in connection with the Merger, for which GSCP will receive customary fees. GSCP has also been retained by Transocean and GlobalSantaFe to act as joint lead arranger, joint bookrunner and administrative agent in respect of the bridge financing, for which GSCP will receive customary fees. Transocean and GlobalSantaFe intend to retain an affiliate of Goldman Sachs to act as joint underwriter, initial purchaser, joint bookrunner and/or joint placement agent for any underwritten public offering or private placement of debt securities issued by Transocean or GlobalSantaFe, in connection with the Transactions, including in connection with any refinancing of the bridge financing, for which such affiliate of Goldman Sachs would receive customary fees.

        In addition, Goldman Sachs has provided and is currently providing certain investment banking and other financial services to Transocean and its affiliates, including having acted in the following transactions: (1) as co-manager of a public offering of 17,940,000 shares of Class A Common Stock of TODCO, a former affiliate of Transocean, in September 2004, (2) as co-manager of a public offering of 14,950,000 shares of Class A Common Stock of TODCO in December 2004, (3) as dealer manager in connection with a tender offer for Transocean's 8% debentures due 2027 (aggregate principal amount $143,000,000) in December 2004, (4) as a participant in a revolving credit facility extended to Transocean (aggregate principal amount $1,000,000,000) in July 2005, (5) as agent in connection with repurchases by Transocean of Transocean ordinary shares in December 2005 and from time to time, and (6) as lead manager of a public offering of Transocean's floating rate notes due September 2008 (aggregate principal amount $1,000,000,000) in September 2006. Goldman Sachs has provided certain investment banking and other financial services to GlobalSantaFe and its affiliates from time to time, including having acted (A) as bookrunner of a public offering of 23,500,000 GlobalSantaFe ordinary shares in April 2005 and (B) as participant in a revolving credit facility extended to GlobalSantaFe (aggregate principal amount $500,000,000) in August 2006. Goldman Sachs also may provide investment banking and other financial services to Transocean, GlobalSantaFe and their respective affiliates in the future. In connection with the above-described services Goldman Sachs has received, and may receive, compensation.

        Goldman Sachs is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman Sachs and its affiliates may provide such services to Transocean, GlobalSantaFe and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of Transocean and GlobalSantaFe for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

        The board of directors of Transocean selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the Merger. Pursuant to a letter agreement dated December 6, 2006, Transocean engaged Goldman Sachs to act as its financial advisor in connection with the Merger. Pursuant to the terms of this engagement letter, Transocean has agreed to pay Goldman Sachs a transaction fee of approximately $28 million, all of which is contingent upon consummation of the Merger. In addition, Transocean has agreed to reimburse Goldman Sachs for its expenses, including attorneys' fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.

Opinion of Lehman Brothers Inc.

        GlobalSantaFe engaged Lehman Brothers to act as its financial advisor in connection with the proposed Merger. On July 21, 2007, Lehman Brothers rendered its oral opinion to the board of directors of GlobalSantaFe, which was subsequently confirmed in writing, that, as of that same date and based upon and subject to certain matters and qualifications stated in the opinion letter, from a financial point of view, the consideration to be offered to GlobalSantaFe's shareholders in the Merger is fair to such shareholders.

        The full text of Lehman Brothers' written opinion dated July 21, 2007, is attached as Annex C to this joint proxy statement. Shareholders are encouraged to read Lehman Brothers' opinion carefully in its entirety for a description of the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by Lehman Brothers in rendering its opinion. The following is a summary of Lehman Brothers' opinion and the methodology that Lehman Brothers used to render its opinion. This summary is qualified in its entirety by reference to the full text of the opinion.

        Lehman Brothers' advisory services and opinion were provided for the information and assistance of the board of directors of GlobalSantaFe in connection with its consideration of the Merger. Lehman Brothers' opinion is not intended to be and does not constitute a recommendation to any shareholder of GlobalSantaFe as to how such shareholder should vote in connection with the Merger. Lehman Brothers was not requested to opine as to, and Lehman Brothers' opinion does not address, GlobalSantaFe's underlying business decision to proceed with or effect the Merger.

        In arriving at its opinion, Lehman Brothers reviewed and analyzed, among other things:

67


        In addition, Lehman Brothers had discussions with the management of GlobalSantaFe and Transocean concerning their respective businesses, operations, assets, financial conditions and prospects and undertook such other studies, analyses and investigations as Lehman Brothers deemed appropriate.

        In arriving at its opinion, Lehman Brothers assumed and relied upon the accuracy and completeness of the financial and other information used by Lehman Brothers without assuming any responsibility for independent verification of such information. Lehman Brothers further relied upon the assurances of the managements of GlobalSantaFe and Transocean that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of GlobalSantaFe, upon advice of GlobalSantaFe, Lehman Brothers assumed that such financial projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of GlobalSantaFe as to the future financial performance of GlobalSantaFe and that GlobalSantaFe will perform substantially in accordance to such projections. With respect to the financial projections of Transocean, upon advice of GlobalSantaFe, Lehman Brothers assumed that such financial projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of GlobalSantaFe as to the future financial performance of Transocean and that Transocean will perform substantially in accordance to such projections. With respect to the expected synergies estimated by the management of GlobalSantaFe to result from a combination of the businesses of GlobalSantaFe and Transocean, upon advice of GlobalSantaFe, Lehman Brothers assumed that such expected synergies will be achieved substantially in accordance with such estimates. In arriving at its opinion, Lehman Brothers did not conduct or obtain any evaluations or appraisals of the assets or liabilities of GlobalSantaFe or Transocean, nor did it conduct a physical inspection of the properties and facilities of GlobalSantaFe and Transocean. Lehman Brothers' opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, July 21, 2007.

        The following is a summary of the material financial analyses used by Lehman Brothers in connection with providing its opinion to the board of directors of GlobalSantaFe. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses used by Lehman Brothers, the tables must be read together with the text of each summary. Considering any portion of such analyses and of the factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying Lehman Brothers' opinion.

        At the effective time of the Reclassification, Transocean shareholders will receive $33.03 in cash and 0.6996 ordinary shares of Transocean for each share of Transocean they own. Immediately thereafter, at the effective time of the Merger, GlobalSantaFe shareholders will receive $22.46 in cash and 0.4757 ordinary shares of Transocean for each share of GlobalSantaFe they own. The implied exchange ratio in the Merger based upon the relative consideration to GlobalSantaFe and Transocean shareholders is 0.680 Transocean ordinary shares per GlobalSantaFe ordinary share.

        Lehman Brothers considered historical data with regard to the trading prices of GlobalSantaFe and Transocean ordinary shares for the period from July 20, 2004, to July 20, 2007, and the relative share price performances during this same period of GlobalSantaFe and Transocean, and the Oilfield Service Index, or the OSX. During this period the closing share price of GlobalSantaFe ranged from a low of $24.53 to a high of $75.85 per share, and the closing share price of Transocean ranged from a low of $25.94 to a high of $111.30 per share. Lehman Brothers noted outperformance or underperformance of GlobalSantaFe ordinary shares in the period reviewed relative to Transocean ordinary shares and the OSX. The foregoing historical share price analysis was presented to the board of directors of GlobalSantaFe to provide it with background information and perspective with respect to the relative historical share prices of GlobalSantaFe and Transocean ordinary shares.

        Lehman Brothers also compared the historical per share prices of GlobalSantaFe and Transocean during different periods during the one year period prior to July 20, 2007, in order to determine the implied average exchange ratio that existed for those periods. The following table indicates the average

        In order to assess how the public market values shares of similar publicly traded companies, Lehman Brothers, based on its experience with companies in the offshore contract drilling industry, reviewed and compared specific financial and operating data relating to GlobalSantaFe and Transocean with selected companies that Lehman Brothers deemed comparable to GlobalSantaFe and Transocean, including:

        Using publicly available information, Lehman Brothers calculated and analyzed equity and capitalization multiples of certain projected financial criteria (such as cash flow from operations, referred to as CFPS, earnings before interest, taxes, depreciation and amortization, referred to as EBITDA, and earnings per share, referred to as EPS). The adjusted capitalization of each company was obtained by adding its outstanding debt to the sum of the market value of its common equity, the value of its preferred stock (the market value if such shares are publicly traded and the liquidation value if such shares are not publicly traded) and the book value of any minority interest minus its cash balance.

        For GlobalSantaFe, the comparable companies methodology yielded a per share equity value range of $65.00 to $80.00. For Transocean, the comparable companies methodology yielded a per share equity value range of $75.00 to $92.50. The implied exchange ratio based upon these valuation ranges is 0.865 to 0.867 shares of Transocean per GlobalSantaFe share.

        Because of the inherent differences between the corporate structure, businesses, operations and prospects of GlobalSantaFe and Transocean and the corporate structure, businesses, operations and prospects of the companies included in the comparable company groups, Lehman Brothers believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the analysis and, accordingly, also made qualitative judgments concerning differences between the financial and

70



operating characteristics of GlobalSantaFe and Transocean and companies in the comparable company groups that would affect the public trading values of GlobalSantaFe and Transocean and such comparable companies.

        As part of Lehman Brothers' analysis, and in order to estimate the present value of GlobalSantaFe and Transocean ordinary shares, it prepared a discounted cash flow analysis for GlobalSantaFe and Transocean, calculated as of January 1, 2008, of after-tax unlevered free cash flows for fiscal years 2008 through 2016. Lehman Brothers ran three discounted cash flow cases including: Case I, Case II and Case III. The projections for each case were prepared by the management of GlobalSantaFe.

        A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of an asset by calculating the "present value" of estimated future cash flows of the asset. Present value refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macro-economic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors. Lehman Brothers performed a discounted cash flow analysis for GlobalSantaFe by adding (1) the present value of GlobalSantaFe's projected after-tax unlevered free cash flows for fiscal years 2008 through 2016 to (2) the present value of the "terminal value" of GlobalSantaFe as of 2016. Terminal value refers to the value of all future cash flows from an asset at a particular point in time.

        With respect to the GlobalSantaFe and Transocean discounted cash flow analyses, Lehman Brothers discounted the unlevered free cash flow streams and the estimated terminal value to a present value at a range of discount rates from 9.0% to 12.0%. The discount rates utilized in this analysis were chosen by Lehman Brothers based on its expertise and experience with the offshore contract drilling industry and also on an analysis of the weighted average cost of capital of GlobalSantaFe, Transocean and other comparable companies. Lehman Brothers estimated terminal values in 2016 calculated based on a perpetuity growth model using discount rates from 9.0% to 12.0% and a growth rate of 3.0%. Lehman Brothers calculated per share equity values by first determining a range of enterprise values of GlobalSantaFe and Transocean by adding the present values of the after-tax unlevered free cash flows and terminal values for each discount rate scenario, and then subtracting from the enterprise values the net debt (which is total debt minus cash) of GlobalSantaFe and Transocean, and dividing those amounts by the number of fully diluted shares of GlobalSantaFe and Transocean.

        The discounted cash flow methodology yielded valuations for GlobalSantaFe that imply a per share equity value range of $47.00 to $63.00 in Case I, $32.00 to $42.00 in Case II and $94.00 to $132.00 in Case III. The discounted cash flow methodology yielded valuations for Transocean that imply a per share equity value range of $80.00 to $115.00 in Case I, $55.00 to $79.00 in Case II and $155.00 to $230.00 in Case III. The implied exchange ratios based upon these valuation ranges are 0.548 to 0.588 in Case I, 0.532 to 0.582 in Case II and 0.574 to 0.606 in Case III.

        Lehman Brothers analyzed the respective contributions of GlobalSantaFe and Transocean to the estimated calendar years 2008 and 2009 revenues and EBITDA, and 2008 net income and cash flow from operations of the combined company based on the Case I projections for revenue and EBITDA and First Call/I/B/E/S consensus estimates for net income and cash flow from operations. Lehman Brothers also analyzed the respective contributions of GlobalSantaFe and Transocean to the total contracted revenue and EBITDA backlog of the combined company. This analysis indicated the

following relative contributions of GlobalSantaFe and Transocean and the pro forma equity ownership of holders of GlobalSantaFe and Transocean ordinary shares in the combined company:

        Lehman Brothers analyzed the pro forma impact of the Merger on the combined company's projected CFPS and earnings, excluding any purchase accounting adjustments. In the pro forma merger consequences, Lehman Brothers prepared a pro forma merger model which incorporated First Call/I/B/E/S consensus estimates for 2008 and 2009 as well as the expected synergies to result from the Merger. Lehman Brothers then compared the CFPS and earnings of GlobalSantaFe and Transocean on a standalone basis to the CFPS and earnings in the pro forma combined company. Lehman Brothers noted that the Merger is accretive to the combined company's pro forma CFPS and earnings in 2008 and 2009 based on First Call/I/B/E/S estimates.(2)


(2)
GlobalSantaFe notes that if standalone 2008 and 2009 estimated earnings per share are adjusted to reflect the reverse stock split in a similar fashion to how historical earnings per share will be adjusted for U.S. GAAP, then, although the Merger by itself is accretive, the Transactions in the aggregate would be dilutive to earnings and cash flow per share. For additional discussions of issues related to accretion and dilution, see "—Accounting Treatment and Considerations" and "—Accretion and Dilution Considerations."

        Lehman Brothers took into consideration price targets from the Wall Street equity research analysts that cover GlobalSantaFe and Transocean. As of July 20, 2007, GlobalSantaFe had 22 analysts that covered the company. For GlobalSantaFe, 16 analysts had a "Buy" rating, three analysts had a "Hold" rating, two analysts had a "Sell" rating and one analyst did not have a rating. The median

target price for GlobalSantaFe was $76.00. The price targets for GlobalSantaFe ranged from $52.00 per share to $89.00 per share. As of July 20, 2007, Transocean had 22 analysts that covered the company. For Transocean, 15 analysts had a "Buy" rating, six analysts had a "Hold" rating and one analyst had a "Sell" rating. The median target price for Transocean was $108.00. The price targets for Transocean ranged from $76.00 per share to $142.00 per share. The implied exchange ratio based upon the price targets for GlobalSantaFe and Transocean is 0.627 to 0.684 shares of Transocean per GlobalSantaFe share.

        Lehman Brothers also took into consideration the NAV per share from third party research. As of July 20, 2007, the median NAV for GlobalSantaFe and Transocean was $53.00 and $66.00, respectively. The implied exchange ratio based upon the NAV estimates is 0.803 shares of Transocean per GlobalSantaFe share.

        In connection with the review of the Merger by the board of directors of GlobalSantaFe, Lehman Brothers performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, Lehman Brothers considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered by it. Furthermore, Lehman Brothers believes that the summary provided and the analyses described above must be considered as a whole and that selecting any portion of its analyses, without considering all of them, would create an incomplete view of the process underlying its analyses and opinion. In addition, Lehman Brothers may have given various analyses and factors more or less weight than other analyses and factors and may have deemed various assumptions more or less probable than other assumptions, so that the ranges of valuations resulting from any particular analysis described above should not be taken to be Lehman Brothers' view of the actual value of GlobalSantaFe or Transocean.

        In performing its analyses, Lehman Brothers made numerous assumptions with respect to industry risks associated with industry performance, general business and economic conditions and other matters, many of which are beyond the control of GlobalSantaFe or Transocean. Any estimates contained in Lehman Brothers' analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates. The analyses do not purport to be appraisals or to reflect the prices at which GlobalSantaFe ordinary shares or Transocean ordinary shares might trade following announcement of the Merger or the prices at which Transocean ordinary shares might trade following consummation of the Merger.

        The terms of the Merger were determined through arm's length negotiations between GlobalSantaFe and Transocean and were unanimously approved by the boards of directors of GlobalSantaFe and Transocean. Lehman Brothers did not recommend any specific exchange ratio or form of consideration to GlobalSantaFe or that any specific exchange ratio or form of consideration constituted the only appropriate consideration for the Merger. Lehman Brothers' opinion was provided to the board of directors of GlobalSantaFe to assist it in its consideration of the exchange ratio in the Merger. Lehman Brothers' opinion does not address any other aspect of the proposed Merger and does constitute a recommendation to any shareholder as to how to vote or to take any other action with respect to the Merger. Lehman Brothers' opinion was one of the many factors taken into consideration by the board of directors of GlobalSantaFe in making its unanimous determination to approve the merger agreement. Lehman Brothers' analyses summarized above should not be viewed as determinative of the opinion of the board of directors of GlobalSantaFe with respect to the value of

73



GlobalSantaFe or Transocean or of whether the board of directors of GlobalSantaFe would have been willing to agree to a different exchange ratio or form of consideration.

        Lehman Brothers is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. The board of directors of GlobalSantaFe selected Lehman Brothers because of its expertise, reputation and familiarity with GlobalSantaFe and the offshore contract drilling industry generally and because its investment banking professionals have substantial experience in transactions comparable to the Merger.

        In the ordinary course of its business, Lehman Brothers may actively trade in the debt or equity securities of GlobalSantaFe and Transocean for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities.

        As compensation for its services in connection with the Merger, GlobalSantaFe paid Lehman Brothers a fee of $3 million for its opinion and an additional $1.5 million fee upon execution of the merger agreement. GlobalSantaFe has also agreed to pay Lehman Brothers a fee of $25.5 million upon the closing of the Merger. In addition, GlobalSantaFe has agreed to reimburse Lehman Brothers for its reasonable out-of-pocket expenses incurred in connection with its engagement, and to indemnify Lehman Brothers and certain related persons against certain liabilities in connection with its engagement. Lehman Brothers in the past has rendered investment banking services to GlobalSantaFe, and its affiliates and received customary fees for such services and Lehman Brothers expects to perform various investment banking services for Transocean in the future for which Lehman Brothers expects to receive customary fees. In addition, at the request of GlobalSantaFe, Lehman Brothers has provided a commitment for a portion of the financing necessary to finance the Merger and will receive customary fees in connection therewith.


Opinion of Simmons & Company International

        GlobalSantaFe retained Simmons & Company to provide a fairness opinion to the board of directors of GlobalSantaFe in connection with the Merger. GlobalSantaFe selected Simmons & Company based upon Simmons & Company's qualifications, reputation and experience in connection with mergers and acquisitions. GlobalSantaFe instructed Simmons & Company to evaluate the fairness, from a financial point of view, of the merger consideration to be received by GlobalSantaFe's shareholders in the Merger.

        On July 21, 2007, Simmons & Company delivered its written opinion to the board of directors of GlobalSantaFe to the effect that, as of that date and based upon and subject to factors and assumptions set forth in its opinion, the merger consideration to be received by GlobalSantaFe's shareholders was fair to GlobalSantaFe's shareholders from a financial point of view. The opinion speaks only as of the date it was delivered and not as of the time the Merger will be completed. The opinion does not reflect changes that may occur or may have occurred after July 21, 2007, which could significantly alter the value of GlobalSantaFe or Transocean or the respective trading prices of their ordinary shares, which are factors on which Simmons & Company's opinion was based.

        The full text of the Simmons & Company fairness opinion dated July 21, 2007, which sets forth the assumptions made, matters considered and qualifications and limitations on the review undertaken, is attached as Annex D to this joint proxy statement and is incorporated into this joint proxy statement by reference. The summary of the Simmons & Company fairness opinion set forth in this joint proxy statement does not describe all aspects of Simmons & Company's opinion and it is qualified in its entirety by reference to the full text of the Simmons & Company fairness opinion. GlobalSantaFe shareholders should read the Simmons & Company fairness opinion carefully and in

74



its entirety. In arriving at its opinion, Simmons & Company did not ascribe a specific value to GlobalSantaFe, but rather made its determination as to the fairness, from a financial point of view, of the merger consideration to be received by GlobalSantaFe's shareholders in the transaction on the basis of the financial and comparative analyses described below. Simmons & Company's opinion is for the use and benefit of the board of directors of GlobalSantaFe and was rendered to the board of directors in connection with its consideration of the Merger. The opinion does not address the merits of the underlying decision of GlobalSantaFe to engage in the transaction contemplated by the merger agreement. GlobalSantaFe's shareholders should not view Simmons & Company's opinion as providing any assurance that the market value of merger consideration to be received in the Merger will be in excess of the market value of GlobalSantaFe ordinary shares owned by such shareholders at any time before the announcement or completion of the Merger. Moreover, it does not constitute a recommendation by Simmons & Company to any GlobalSantaFe shareholder as to how such shareholder should vote or make any election with respect to the Merger.

        In reaching its opinion, Simmons & Company reviewed and analyzed, among other things, the following:

        Simmons & Company also considered such other information, financial studies, analysis and investigations and financial, economic and market criteria which Simmons & Company deemed relevant. Simmons & Company also met with officers and employees of GlobalSantaFe and Transocean to discuss the foregoing, as well as other matters believed relevant to Simmons & Company's analysis.

75



        Simmons & Company did not independently verify any of the foregoing information and has relied on it being complete and accurate in all material respects. With respect to financial forecasts, Simmons & Company utilized certain information set forth in those forecasts and assumed such information was reasonably prepared on bases reflecting the best estimates and judgments, as available at the time of preparation, of management of GlobalSantaFe on the future financial performance of GlobalSantaFe and Transocean. Simmons & Company did not conduct a physical inspection of any of the assets, operations or facilities of GlobalSantaFe or Transocean and did not make or receive any independent evaluation or appraisal of any assets or liabilities, contingent or otherwise, of GlobalSantaFe or Transocean. Simmons & Company did not perform any tax or regulatory analysis nor was Simmons & Company furnished with any such analysis. Accordingly, Simmons & Company did not evaluate (and Simmons & Company's opinion does not include) any potential tax or regulatory consequences related to the Merger including, without limitation, any potential tax or regulatory consequences to GlobalSantaFe, Transocean or their respective shareholders. In addition, Simmons & Company was not authorized to solicit, and did not solicit, any indications of interest from any third party with respect to the purchase of all or part of GlobalSantaFe's business.

        In preparing its fairness opinion for the board of directors of GlobalSantaFe, Simmons & Company performed a variety of financial and comparative analyses, including those described below. The summary of the analyses performed by Simmons & Company, as set forth below, does not purport to be a complete description of the analyses underlying the opinion. The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, fairness opinions are not readily susceptible to partial or summary description. No company or transaction used in such analyses as a comparison is identical to GlobalSantaFe, Transocean or the transaction contemplated by the merger agreement, nor is an evaluation of the results of such analyses entirely mathematical; rather, it involves complex considerations and judgments concerning financial and operational characteristics and other factors that could affect the public trading or other values of the companies or transactions being analyzed. The estimates contained in such analyses and the ranges of valuations resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by such analyses. In addition, analyses relating to the value of the business or securities do not purport to be appraisals or to reflect the prices at which businesses, companies or securities actually may be sold. Accordingly, such analyses and estimates are subject inherently to substantial uncertainty.

        In arriving at the fairness opinion, Simmons & Company made qualitative judgments as to the significance and relevance of each analysis as well as other data considered by Simmons & Company. Accordingly, Simmons & Company believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors, without considering all analyses and factors, could create an incomplete view of the processes underlying such analyses and the fairness opinion. In its analyses, Simmons & Company made numerous assumptions with respect to general business, economic, market and financial conditions, as well as other matters, many of which are beyond the control of GlobalSantaFe and Transocean and involve the application of complex methodologies and experienced and educated judgment.

        The analyses were prepared solely as part of Simmons & Company's analysis of the fairness, from a financial point of view, to GlobalSantaFe shareholders of the merger consideration to be received in the proposed Merger.

        Simmons & Company's opinion and financial analyses were only one of the many factors considered by management of GlobalSantaFe and the board of directors of GlobalSantaFe in their evaluation of the Merger and should not be viewed as determinative of the views of management of

76



GlobalSantaFe or the board of directors of GlobalSantaFe with respect to the Merger and the merger consideration.

        The data and analysis summarized herein is from Simmons & Company's presentation to the board of directors of GlobalSantaFe delivered on July 21, 2007, which primarily utilized data from market closing prices as of July 20, 2007. For purposes of its analysis, Simmons & Company defined EBITDA as net income plus income taxes, interest expense (less interest income), depreciation and amortization. Cash flow represents net income plus depreciation and amortization.

        In the Merger, GlobalSantaFe's shareholders will receive 0.4757 ordinary shares of Transocean and $22.46 for each ordinary share of GlobalSantaFe. Immediately prior to the Merger, each outstanding ordinary share of Transocean will be reclassified by way of a scheme of arrangement under Cayman Islands law into 0.6996 ordinary shares of Transocean and $33.03. These figures represent the outcome of a negotiated share exchange ratio of 0.680x (the number of GlobalSantaFe ordinary shares per Transocean ordinary share) and a distribution of $15.0 billion to the shareholders of Transocean and GlobalSantaFe. Based on this share exchange ratio, ordinary shares currently owned by GlobalSantaFe's shareholders would comprise approximately 34% of the ordinary shares of the combined company.

        In determining its opinion, Simmons & Company focused on the relative valuations of GlobalSantaFe and Transocean to assess whether a 0.680x share exchange ratio was fair to GlobalSantaFe's shareholders from a financial point of view. Simmons & Company also considered whether the distribution of $15.0 billion to the shareholders of Transocean and GlobalSantaFe was fair to GlobalSantaFe's shareholders from a financial point of view.

        Simmons & Company performed a discounted cash flow analysis of GlobalSantaFe and Transocean using financial forecasts through 2016 as provided by GlobalSantaFe. A total of three cases were analyzed with each case reflecting different levels of industry performance and financial performance by rig type. Terminal values in 2016 were based on 7.0x and 9.0x EBITDA. Discount rates of 9% to 13% were used to discount annual free cash flows and terminal values to derive an assessment of the enterprise value of GlobalSantaFe and Transocean. Simmons & Company then converted implied enterprise values to implied share prices for each company based on their respective capital structure and shares outstanding. Finally, share prices were converted to implied share exchange ratios. The share exchange ratios suggested by the discounted cash flow analysis were in the range of 0.618x to 0.690x.

77


        Simmons & Company analyzed implied share exchange ratios based on each company's relative contributions of EBITDA and EBITDA less maintenance capital expenditures as provided by GlobalSantaFe's management. Relative contribution analysis was done for each of the three cases utilized in the discounted cash flow analysis and each of the projected years ending December 31, 2007 through December 31, 2012. The results of this analysis are summarized as follows:

 
  Implied Share
Exchange Ratio

EBITDA    
2007   0.925x - 0.928x
2008   0.774x - 0.802x
2009   0.534x - 0.747x
2010   0.461x - 0.678x
2011   0.422x - 0.626x
2012   0.354x - 0.602x

EBITDA less Maintenance Capital Expenditures

 

 
2007   0.946x - 0.949x
2008   0.773x - 0.804x
2009   0.508x - 0.743x
2010   0.405x - 0.669x
2011   0.332x - 0.613x
2012   0.244x - 0.588x

        Simmons & Company also reviewed implied share exchange ratios based on each company's relative contributions based on third party research analyst estimates of EBITDA, EBITDA less maintenance capital expenditures and net income for years ending December 31, 2007 through December 31, 2009. These financial forecasts imply share exchange ratios of 0.912x - 0.951x in 2007, 0.802x - 0.831x in 2008 and 0.800x - 0.854x in 2009. However, Simmons & Company did not particularly weigh the implied share exchange ratios suggested by third party analyst estimates as such estimates reflect a limited time period that does not fully capture the potential impact of assets under construction for each company as well as contracts awarded to each company.

        Simmons & Company reviewed and compared certain financial, operating and stock market information of GlobalSantaFe and Transocean to corresponding information of seven publicly traded, offshore drilling companies. Also, Simmons & Company subjectively classified each of these seven companies into two groups: those that were oriented towards jackup drilling rigs, or the Jackup-Oriented Group, and those that were oriented towards floating drilling rigs, or the Floater-Oriented Group. The Jackup-Oriented Group included ENSCO International Inc., Noble Corporation, Hercules Offshore, Inc. and Rowan Companies, Inc. The Floater-Oriented Group included Atwood Oceanics, Inc., Diamond Offshore Drilling, Inc. and Ocean Rig ASA.

        For GlobalSantaFe, Transocean and each of the comparable companies, Simmons & Company reviewed the following ratios for the year ended December 31, 2007 and the year ended December 31, 2008:

78


        Simmons & Company utilized third-party research estimates for each company's earnings per share. Adjustments to convert earnings per share to cash flow per share and EBITDA were based on data from third-party research analysts and Simmons & Company's research group. Adjusted market value, as used by Simmons & Company in its analysis, means equity value (the number of fully diluted shares outstanding multiplied by the closing share price as of July 20, 2007) plus debt and minority interests and less cash and any investment in unconsolidated affiliates.

        The following table sets forth the results of this analysis:

 
  Jackup-Oriented Group
  Floater-Oriented Group
 
  Range
  Median
  Range
  Median
Ratio Of Adjusted Market Value To:                
2007P EBITDA   4.8x - 7.9x   6.1x   8.8x - 13.4x   11.7x
2008P EBITDA   4.1x - 5.7x   5.1x   5.7x - 8.8x   6.2x

Ratio Of Equity Value To:

 

 

 

 

 

 

 

 
2007P Net Income   8.1x - 11.4x   9.9x   14.0x - 34.7x   16.7x
2008P Net Income   6.6x - 8.6x   7.7x   8.6x - 10.8x   8.6x
2007P Cash Flow   5.4x - 9.1x   8.1x   11.6x - 14.6x   13.4x
2008P Cash Flow   4.7x - 7.1x   6.6x   7.5x - 7.6x   7.5x

        Based on the above data, Simmons & Company subjectively selected a range of ratios for GlobalSantaFe and Transocean for each of the above measures and time periods. These ratio ranges were then used to determine an implied share price for GlobalSantaFe and Transocean. Generally, Simmons & Company placed more emphasis on the Jackup-Oriented Group when selecting multiples for GlobalSantaFe. For Transocean, Simmons & Company generally placed more emphasis on the Floater-Oriented Group. The following table sets forth the range of multiples selected:

 
  GlobalSantaFe
Suggested Range

  Transocean
Suggested Range

Ratio Of Adjusted Market Value To:        
2007P EBITDA   6.0x - 8.0x   9.0x - 12.0x
2008P EBITDA   5.0x - 6.0x   6.0x - 8.0x

Ratio Of Equity Value To:

 

 

 

 
2007P Net Income   9.0x - 11.0x   13.0x - 17.0x
2008P Net Income   7.5x - 8.5x   8.5x - 10.0x
2007P Cash Flow   7.5x - 8.5x   10.0x - 13.0x
2008P Cash Flow   6.0x - 7.0x   7.0x - 8.0x

        Implied share prices for GlobalSantaFe and Transocean were then used to determine an implied share exchange ratio range for each measure and time period. The results of this analysis suggested a share exchange ratio range of 0.590x to 0.720x.

        Simmons & Company calculated the share exchange ratios implied by asset replacement values and net asset values based on the following:

79


        The results of these analyses suggested an implied share exchange ratio of 0.701x based on asset replacement values and 0.762x based on net asset values. Simmons & Company did not emphasize the relative asset value analysis in arriving at its opinion as Simmons & Company did not believe the analysis captures the value of the respective businesses as ongoing enterprises. Furthermore, the data available from third-party research analysts is based on limited available information on recent sales of rigs similar to those in the GlobalSantaFe and Transocean rig fleets.

        Simmons & Company derived implied historical share exchange ratios by dividing the closing price of the GlobalSantaFe ordinary shares by the closing price of the Transocean ordinary shares for each trading day over varying time periods. Such derived share exchange ratios were used by Simmons & Company as a basis for comparison with the share exchange ratio as of July 20, 2007, which is approximately equal to the actual share exchange ratio. The following table sets forth the results of this analysis:

 
  Share
Exchange Ratio

  Premium To Ratio as of
July 20, 2007

 
Ratio As Of July 20, 2007   0.680x   0.0 %
30-Day Average   0.679x   0.1  
90-Day Average   0.703x   (3.3 )
180-Day Average   0.729x   (6.8 )
1-Year Average   0.725x   (6.3 )
Since January 2006   0.727x   (6.5 )

        Simmons & Company understands GlobalSantaFe and Transocean have received a commitment letter for a bridge loan that, when combined with estimated cash on hand at closing, will allow $15.0 billion to be distributed to shareholders of Transocean and GlobalSantaFe. Simmons & Company reviewed the calculations as to how the cash distribution would be allocated to shareholders. A summary of these calculations is as follows:

        Simmons & Company's opinion does not address the underlying business decision for the combined company to incur new debt to fund the above distribution to shareholders.

        Simmons & Company is an internationally recognized investment banking firm specializing in the energy industry and is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions. GlobalSantaFe selected Simmons & Company to provide a fairness opinion in connection with the Merger because of Simmons & Company's experience and expertise. In the ordinary course of its business, Simmons & Company actively trades the debt and

80


equity securities of both GlobalSantaFe and Transocean for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities.

        Simmons & Company in the past has provided investment banking services to GlobalSantaFe for which it received customary compensation and reimbursement of expenses. Simmons & Company has also previously provided investment banking and financial advisory services to Transocean for which it has received customary compensation. Simmons & Company anticipates that it may act as financial adviser to Transocean with respect to future transactions.

        Pursuant to the terms of the engagement of Simmons & Company, GlobalSantaFe paid Simmons & Company an initial fee of $250,000 and an additional fee of $1,750,000 for rendering its opinion. In addition, GlobalSantaFe has agreed to reimburse Simmons & Company for its reasonable out-of-pocket expenses incurred in connection with the engagement, including the fees and expenses of its legal counsel, and to indemnify Simmons & Company against certain liabilities that may arise out of the engagement, including certain liabilities under federal securities laws.


Interests of Certain Persons in the Transactions

        You should be aware that Transocean and GlobalSantaFe directors and executive officers have interests in the Transactions as directors or officers that are different from, or in addition to, the interests of other Transocean and GlobalSantaFe shareholders.

Governance and Management of Transocean Following the Transactions

        After the Transactions, Transocean will have a board of directors that consists of 14 members, which will include seven directors designated by Transocean's board of directors and seven directors designated by GlobalSantaFe's board of directors.

81


described under "—Governance and Management of Transocean Following the Transactions." Under the terms of the Transocean articles of association to be in effect at the closing of the Transactions, prior to the second anniversary of the effective date of the Transactions, any vacancy on Transocean board of directors that relates to a director who was previously a Transocean director will be filled by the other former Transocean directors who are on the Transocean board.

        At the effective time of the Merger, Robert L. Long, the current Chief Executive Officer of Transocean, will continue in that position. Under the terms of the Transocean articles of association to be in effect at the closing of the Transactions, any action taken prior to the second anniversary of the effective time of the Transactions to remove, replace or appoint a new chief executive officer of Transocean will require the approval of two-thirds of the entire board of directors of Transocean.

        Under the terms of Transocean's Long-Term Incentive Plan, which applies to nonemployee directors, officers and other key employees, all outstanding and unvested options to purchase Transocean ordinary shares, share appreciation rights, deferred units and restricted shares will vest upon a change of control, as defined in the plan. The Transactions will constitute a change of control, as defined in, and construed under, the plan for purposes of awards made under the plan prior to July 21, 2007. The stock options that vest will be exercisable for the duration of their term, notwithstanding an optionee's termination of employment or cessation of service as a director. The stock options will also be adjusted in connection with the Reclassification. See "The Transactions—Adjustment of Transocean Stock Options" for further information. In the case of deferred units and restricted shares granted to nonemployee directors, officers and other key employees in July 2007, as a result of the Transactions, the grantees of the awards will receive a cash payment for the portion of their unvested deferred units and restricted shares corresponding to the cash payment in the Reclassification.

        As of August 22, 2007, the non-employee directors of Transocean held the following deferred units that will vest as a result of the Transactions:

While the restricted shares and deferred units awarded to Transocean's executive officers in July 2007 will not vest as a result of the Transactions, the executive officers will receive the following cash payments for those restricted shares and deferred units pursuant to the Reclassification: Robert L. Long ($1,869,432), Jean P. Cahuzac ($787,138), Steven L. Newman ($713,349), Eric B. Brown ($426,351), Gregory L. Cauthen ($426,351), David J. Mullen ($229,592) and David A. Tonnel ($131,195).

        Under Transocean's Performance Award and Cash Bonus Plan, upon a change of control as defined in the plan, plan participants will be deemed to have fully attained all performance objectives under the plan. The Transactions will constitute a change of control for purposes of the plan. Therefore, performance awards for the portion of the performance period prior to the change of control will be deemed to be the maximum amount of the award that could have been earned assuming full attainment of the performance objectives. Transocean's executive officers participate in this plan. The executive officers of Transocean would receive the following payments for 2007 under the plan (assuming a closing date of December 31, 2007):

Robert L. Long   $ 2,389,250
Jean P. Cahuzac   $ 1,135,102
Steven L. Newman   $ 811,241
Eric B. Brown   $ 590,098
Gregory L. Cauthen   $ 677,944
David J. Mullen   $ 481,531
David A. Tonnel   $ 241,063

        Under Transocean's Executive Change of Control Severance Benefit, a covered executive officer is eligible to receive benefits if Transocean terminates the executive officer other than for "cause" (as defined in the policy) or the executive officer resigns for "good reason" (as defined in the policy) following the change of control. Robert L. Long, Jean P. Cahuzac, Eric B. Brown and Gregory L. Cauthen are covered under the policy. The Transactions will constitute a change in control as defined in, and construed under, the policy.

        This policy provides that these executive officers who, within 24 months after a change of control, are terminated by Transocean without "cause" (as defined in the policy) or leave Transocean for "good reason" (as defined in the policy) will receive, in addition to compensation and benefits accrued up to the point of termination, the following:

(a)
Reflects an assumed share price of $101.14 based on the closing price of Transocean ordinary shares on August 22, 2007 multiplied by the remaining 2007 restricted shares and deferred units after the Reclassification, which would fully vest in connection with a termination by Transocean without cause or an executive leaving Transocean for good reason pursuant to the Executive Change of Control Severance Benefit.

        Transocean does not currently expect any covered executive officer to be terminated in connection with the Transactions. However, if any covered executive officer is terminated by Transocean without cause or leaves Transocean for good reason within 24 months after the completion of the Transactions, such covered executive officer would be eligible to receive severance benefits.

        Siem Industries, Inc., an affiliate of Kristien Siem, a director of Transocean, holds 500,000 ordinary shares of GlobalSantaFe. Siem Industries has indicated that it intends to vote its shares in favor of the GlobalSantaFe proposal.

Interests of GlobalSantaFe Directors and Executive Officers in the Transactions

        In considering the recommendations of the GlobalSantaFe board of directors with respect to the merger agreement, you should be aware that GlobalSantaFe's directors and executive officers have financial and other interests in the Merger in addition to their interests as shareholders of GlobalSantaFe. The GlobalSantaFe board of directors was aware of these additional interests and considered them, among other matters, in reaching its decision to approve the merger agreement and to recommend that GlobalSantaFe shareholders vote to approve the Merger.

        At the effective time of the Merger, the board of directors of Transocean will be comprised of seven persons who were designated by Transocean from its current board of directors and seven persons who were designated by GlobalSantaFe from its current board of directors, as more particularly described under "—Governance and Management of Transocean Following the Transactions." Under the terms of the Transocean articles of association to be in effect at the closing of the Transactions, prior to the second anniversary of the effective date of the Merger, any vacancy on Transocean board of directors that relates to a director who was previously a GlobalSantaFe director will be filled by a designee selected by the other former GlobalSantaFe directors who are on the Transocean board. The merger agreement further provides that, at the effective time of the Merger, Robert E. Rose, the current chairman of the board of directors of GlobalSantaFe, will become chairman of the board of directors of Transocean. Under the terms of the Transocean articles of association to be in effect at the closing of the Transactions, any action taken prior to the second anniversary of the effective time of the Merger to remove, replace or appoint a new chairman of the board of Transocean will require the approval of two-thirds of the entire board of directors of Transocean.

        At the effective time of the Merger, Jon A. Marshall, the current Chief Executive Officer and President of GlobalSantaFe, will be the President and Chief Operating Officer of Transocean. Under the terms of the Transocean articles of association to be in effect at the closing of the Transactions, any action taken prior to the second anniversary of the effective time of the Merger to remove, replace or appoint a new president and chief operating officer of Transocean will require the approval of two-thirds of the entire board of directors of Transocean.

        In addition, the parties have agreed that the following officers of GlobalSantaFe will serve as officers of Transocean: Cheryl D. Richard will serve as Senior Vice President, Human Resources and Information Technology, and Robert L. Herrin will serve as Vice President, Audit and Advisory Services. Under the terms of the merger agreement, until December 31, 2008, Transocean will provide the employees of GlobalSantaFe as of the day immediately prior to the effective time of the Merger, including these individuals, with salary and (in the aggregate) other employee compensation and benefits no less favorable than the salary and other employee compensation and benefits that they were receiving from GlobalSantaFe at the effective time of the Merger. See "—Employee Benefits Matters" below.

        Furthermore, Transocean has agreed to assume the severance agreements between GlobalSantaFe and certain of its employees, including those of Ms. Richard and Mr. Marshall.

        Pursuant to their governing instruments, all GlobalSantaFe options to acquire GlobalSantaFe ordinary shares and stock-settled stock appreciation rights, or GlobalSantaFe SARs, including GlobalSantaFe options and SARs held by directors and executive officers of GlobalSantaFe, that are outstanding at the time of shareholder approval of the Merger will become vested and exercisable at that time. The merger agreement provides that each outstanding GlobalSantaFe option and

85


GlobalSantaFe SAR will become exercisable for Transocean ordinary shares immediately following the effective time of the Merger. In addition, GlobalSantaFe options and SARs that would otherwise expire under their terms will be deemed modified to remain exercisable for their full scheduled term in the event the holder thereof is involuntarily terminated for any reason other than cause within twelve months after the effective time of the Merger. Each outstanding GlobalSantaFe stock unit will be exchanged for and converted into the GlobalSantaFe merger consideration. For a more complete description of the terms of the treatment of the GlobalSantaFe options, SARs and stock units, please see "GlobalSantaFe Options, Stock Units and SARs and Assumption of GlobalSantaFe stock plans." Ms. Richard and Messrs. Marshall, Ralls, Dawson, Hunt and McCulloch have agreed that their unvested options and SARs will not become vested and exercisable upon shareholder approval of the Merger, rather that such vesting and exercisability shall occur upon consummation of the Merger. These individuals have also agreed that their stock units will not become payable upon shareholder approval of the Merger, but rather will become payable either upon consummation of the Merger or by March 14 of the year following the year in which shareholder approval occurs.

        Each executive officer of GlobalSantaFe holds cash-based performance units that were awarded by GlobalSantaFe in 2005. Pursuant to their governing instruments, the performance units each have a $25 cash target value and will pay out at, above or below $25 (with a $0 minimum and a $50 maximum) depending on GlobalSantaFe's performance during a three-year performance period ending December 31, 2007, as measured by GlobalSantaFe's return on invested capital and total shareholder return relative to a peer group of its competitors. Pursuant to their governing instruments, all performance units that are outstanding at the time of GlobalSantaFe shareholder approval of the Merger will be paid (a) at the $25 target value if shareholder approval occurs during 2007, such payment to be made on the date of such approval, or (b) at the value determined by GlobalSantaFe's actual performance during the three-year performance period if shareholder approval occurs after 2007, such payment to be made as soon as practicable after December 31, 2007, but, pursuant to the merger agreement, no later than March 14, 2008; provided, however, that GlobalSantaFe could provide that all outstanding performance units will instead be paid (c) at the value determined by GlobalSantaFe's actual performance during that portion of the three-year performance period ending immediately prior to the effective time of the Merger, such payment being made by March 14, 2008, which would require approval by GlobalSantaFe's Compensation Committee and, in the case of the Chief Executive Officer, ratification by GlobalSantaFe's independent directors and, if shareholder approval occurs during 2007 and the payment is made after shareholder approval, or if such payment is less than the payment that would otherwise be made, the consent of the holder of the performance units. If the Performance Units were to become payable at the $25 target value upon shareholder approval of the Merger in 2007, the value of the Performance Units held by each executive officer would be as follows: Ms. Richard—$235,000; Mr. Marshall—$925,000; Mr. Ralls—$487,500; Mr. Dawson—$274,500; Mr. Herrin—$40,000; Mr. Hunt—$312,500; Mr. McCulloch—$387,500; Mr. Morrison—$42,700; and Mr. Simmons—$250,000.

        Each GlobalSantaFe executive officer is also a participant in the GlobalSantaFe 2007 Annual Incentive Plan, which provides for cash bonuses based on GlobalSantaFe's and the individual participant's performance during 2007. Pursuant to the terms of the plan, the annual bonuses will be paid, at the discretion of GlobalSantaFe's Compensation Committee, as soon as practicable after December 31, 2007, but, pursuant to the merger agreement, no later than March 14, 2008. GlobalSantaFe could, however, determine prior to the effective time of the Merger that such bonuses will instead be paid based on performance during only a portion of 2007, ending before the determination is made, which would require approval by GlobalSantaFe's Compensation Committee and, in the case of the Chief Executive Officer, ratification by GlobalSantaFe's independent directors.

        Eight of GlobalSantaFe's executive officers, Ms. Richard and Messrs. Marshall, Ralls, Dawson, Hunt, McCulloch, Morrison and Simmons, have severance agreements with GlobalSantaFe that include enhanced severance after a change in control. The agreements provide severance benefits in the event of termination of employment other than for "cause" or in the event of voluntary termination for "good reason" (as such terms are defined in the agreements). If there is a change in control of GlobalSantaFe (defined as shareholder approval of the Merger) and the executive has a qualifying termination of employment within the three years following the change in control, the severance benefits include:

        Prior to entering into the merger agreement, the GlobalSantaFe board of directors approved the amendment of the severance agreement of Mr. Marshall to extend the period in which he may give notice that a "good reason" event has occurred under his severance agreement from six months to twenty-four months, to provide that he will not be considered to have consented to any event which would otherwise constitute "good reason" under his severance agreement without a signed writing specifically referring to the severance agreement's provision, and to confirm the application of the change-in-control definition in his severance agreement within the context of the merger agreement. In addition, the GlobalSantaFe board of directors approved the amendment of the severance agreements of each of Ms. Richard and Messrs. Ralls, Dawson, Hunt, McCulloch, Morrison and Simmons to provide that the officer will not be considered to have consented to any event that would otherwise constitute "good reason" under the executive officer's severance agreement without a signed writing specifically referring to the severance agreement's provision, and to confirm the application of the change-in-control definition in the executive officer's severance agreement within the context of the merger agreement.

        The table below sets forth the potential payments to each GlobalSantaFe executive officer assuming a closing date of December 31, 2007, and assuming the employment of the executive officer is terminated by Transocean without cause or the executive officer leaves Transocean for good reason on January 1, 2008. Ms. Richard and Messrs. Marshall and Morrison are expected to continue as officers with the combined company and, as a result, will not become entitled to the potential payments, except for the portion of the payments that relates solely to a change in control (as described in footnotes

88



(b) and (d) to the table), unless they leave the combined company for good reason or are terminated without cause within three years following the change in control.

(a)
Amount equal to three times annual base salary, which would be paid as 36 months of salary continuation and an amount equal to three times the highest bonus paid or payable in any one year to the executive officer during the prior three years.

(b)
The amounts in this row describe "single-trigger" benefits, which vest or become payable solely because a change in control occurs under their governing instruments.

(c)
This amount reflects the incremental present value of the continued accrual of service for the salary continuation period for purposes of all pension benefits and the immediate vesting of the executive's SERP benefits as if the executive had attained at least age 55 and at least five years of service. In addition, in the case of Mr. Ralls, this amount reflects the incremental present value of his supplemental agreement, which provides that if his employment is terminated for any reason after he attains age 58, he is entitled to immediate vesting of benefits under the SERP as if he had attained age 62 and 15 years of service and the bonus used to compute benefits shall be the greater of the actual bonus or $250,000. The amounts set forth represent only the present value of the additional benefit derived from these enhancements and do not include the present value of the regular pension benefits that would also be payable. The present value of the regular pension benefits that would also be payable are as follows: Mr. Marshall—$11,701,997; Mr. Ralls—$6,533,582; Mr. McCulloch—$4,271,244; Mr. Dawson—$1,615,983; Mr. Simmons—$1,175,882; Ms. Richard—$467,909; Mr. Morrison—$694,345; and Mr. Hunt—$4,572,601.

(d)
The amounts in this row describe "single-trigger" benefits, which vest or become payable solely because a change in control occurs under their governing instruments. The equity award values are based on the closing price of $67.15 per share on August 22, 2007. Ms. Richard and Messrs. Marshall, Ralls, Dawson, Hunt and McCulloch have agreed that their unvested options and SARs will not become vested and exercisable upon shareholder approval of the Merger, rather that such vesting and exercisability shall occur upon consummation of the Merger. These individuals have also agreed that their stock units will not become payable upon shareholder approval of the Merger, but rather will become payable either upon consummation of the Merger or on March 14 of the year following the year in which shareholder approval occurs. Provided that an executive officer's employment is not terminated without cause and the executive officer does not leave employment for good reason following the change in control, then only the single-trigger benefits will vest or become payable, no excise tax will be incurred, and the total change-in-control benefits for the executive will be as follows: Mr. Marshall—$9,532,634; Mr. Ralls—$4,807,678; Mr. McCulloch—$3,529,182; Mr. Dawson—$3,038,277; Mr. Simmons—$2,624,194; Ms. Richard—$2,278,779; Mr. Morrison—$1,123,469; and Mr. Hunt—$3,503,223.

        Transocean has also agreed to provide indemnification to, and maintain directors' and officers' liability insurance for, the GlobalSantaFe directors and officers as described under "The Merger Agreement—Covenants—Indemnification and Directors' and Officers' Insurance."


Exchange of Transocean Ordinary Shares and GlobalSantaFe Ordinary Shares for Transocean Ordinary Shares

        Each Transocean ordinary share outstanding immediately prior to the effective time of the Reclassification will be reclassified as, and exchanged for, 0.6996 Transocean ordinary shares and $33.03 in cash. Each GlobalSantaFe ordinary share outstanding immediately prior to the effective time of the Merger will be exchanged for 0.4757 Transocean ordinary shares (after giving effect to the Reclassification) and $22.46 in cash. To allow Transocean and GlobalSantaFe shareholders to exchange their certificates for Transocean ordinary shares, Transocean will deposit with an exchange agent Transocean ordinary shares to be issued and cash to be paid in connection with the Transactions (plus cash in lieu of fractional shares and unpaid distributions, if any) that will be issued in exchange for Transocean ordinary shares and GlobalSantaFe ordinary shares. The exchange agent will then mail to each holder of record of Transocean ordinary shares and GlobalSantaFe ordinary shares a transmittal form that will contain instructions for the surrender of Transocean or GlobalSantaFe ordinary share certificates to be exchanged in the Transactions. Holders of Transocean or GlobalSantaFe ordinary shares who surrender to the exchange agent their share certificates, along with the transmittal form, will receive the number of Transocean ordinary shares that they are entitled to receive and a check representing the aggregate amount of cash consideration and cash in lieu of fractional shares and unpaid dividends and distributions that the shareholders may have a right to receive. Transocean intends to implement a direct registration system at the closing of the Transactions under which all of the Transocean ordinary shares issued in the Transactions will be issued in uncertificated book-entry form.

        The surrendered Transocean and GlobalSantaFe certificates will be canceled. If any Transocean or GlobalSantaFe share certificates are presented to Transocean or the exchange agent after the effective time of the Transactions, then those certificates will be canceled and exchanged for Transocean ordinary shares and a check representing the aggregate amount of cash consideration and cash in lieu of fractional shares that a holder of Transocean or GlobalSantaFe shares, as applicable, is entitled to receive under the merger agreement.

        None of Transocean, the exchange agent or any other person will be liable to any former Transocean or GlobalSantaFe shareholder for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.


Employee Benefits Matters

        At the effective time of the Merger, all employees of Transocean, GlobalSantaFe and their subsidiaries as of the day immediately prior to the effective time (the "Affected Employees") initially will continue to be employed by Transocean and its subsidiaries at the same salaries and wages of such employees immediately prior to the Merger. During the period from the effective time until December 31, 2008, Transocean will:

90


        With respect to each Affected Employee, Transocean will credit the period of employment and service recognized by the applicable employer immediately prior to the effective time to have been employment and service with Transocean for purposes of determining the employee's eligibility to join (subject to satisfaction of all nonservice-related eligibility criteria) and vesting (but not benefit accrual for any purpose other than vacation pay, severance and termination pay, sick leave and post-retirement health coverage and satisfaction of early retirement criteria) under all employee benefit plans, programs, policies or similar employment-related arrangements of Transocean in which the Affected Employee is eligible to participate; provided, however, that no such credit shall be provided to the extent it would result in a duplication of credit or benefits. Transocean will waive, and to the extent necessary to effect the provisions of the merger agreement, will use its best efforts to cause the relevant insurance carriers and other third parties to waive, any restrictions and limitations for medical conditions existing as of the effective time of the Merger of those employees and their dependents who were covered immediately prior to the effective time of the Merger under a group health plan maintained by Transocean or GlobalSantaFe, but only to the extent that this medical condition would be covered by Transocean's group health plan if it were not a preexisting condition and only to the extent that such limitations would not have applied under Transocean or GlobalSantaFe's group health plan prior to the effective time of the Merger.

        Transocean will offer at the effective time of the Merger to each Affected Employee coverage under a group health plan which credits such employee towards the deductibles, coinsurance and maximum out-of-pocket provisions imposed under such group health plan, for the year during which the effective time of the Merger (or such later date as the employees participate in such group health plan) occurs, with any applicable expenses already incurred during such year under Transocean or GlobalSantaFe's group health plan.

        Transocean will establish a severance plan, effective for no less than the period from the effective time of the Merger until the second anniversary of the effective time, for the benefit of Affected Employees on a U.S. dollar payroll who are eligible to participate.

        Transocean will pay to each Affected Employee who was employed by Transocean immediately prior to the effective time of the Merger an amount, to the extent then unpaid, equal to the annual incentive bonus to which the Affected Employee would be entitled under the terms of Transocean's 2007 Performance Award and Cash Bonus Plan and applicable award letters. No later than March 14, 2008, Transocean will pay to each Affected Employee who was employed by GlobalSantaFe immediately prior to the effective time of the Merger (or if the effective time has not yet occurred on March 14, 2008, GlobalSantaFe will pay to each person who is an employee of GlobalSantaFe by such date) amounts equal to:

        If the employment of an Affected Employee who would otherwise be entitled to a payment under the first and/or second bullet above is involuntarily terminated, or such an Affected Employee voluntarily terminates employment after attaining age 55 and five years of service, prior to March 14, 2008, the payment or payments will nevertheless be made to such Affected Employee by March 14, 2008.

91



        In the event the effective time occurs in 2008, immediately prior to the effective time:

        All Transocean cash-settled stock appreciation rights outstanding at the effective time of the Reclassification will remain outstanding following such effective time, except that immediately following such effective time:

        The matters described in this section are summaries of provisions of the merger agreement that are subject to waiver or amendment by the parties to the merger agreement. These provisions are not intended to grant third-party beneficiary rights to any person that is not a party to the merger agreement.


Adjustment of Transocean Stock Options

        At the effective time of the Reclassification, all outstanding options to acquire Transocean ordinary shares will remain outstanding and will become fully vested and exercisable. Immediately following the effective time of the Reclassification:

92


        In addition, Transocean options that would otherwise expire under their terms will be deemed modified to remain exercisable for their full scheduled term in the event the holder of any such Transocean option is involuntarily terminated for any reason other than cause within twelve months after the effective time of the Merger.

        For purposes of this joint proxy statement, (1) "VWAP" means, as of any specified date, the volume-weighted average price per share of Transocean ordinary shares on the New York Stock Exchange during the period beginning at 9:30 a.m., New York City time (or such other time as is the official open of trading on the New York Stock Exchange) and ending at 4:00 p.m., New York City time (or such other time as is the official close of trading on the New York Stock Exchange), as calculated by Xignite, Inc., (2) the "Transocean Adjustment Fraction" means (A) the VWAP of the Transocean ordinary shares on the last trading day immediately preceding the closing date of the Transactions, divided by (B) the Post-Closing Transocean Ordinary Share Fair Market Value, and (3) the "Post-Closing Transocean Ordinary Share Fair Market Value" means (A) the VWAP of the Transocean ordinary shares on the last trading day immediately preceding the closing date of the Transactions minus $33.03, divided by (B) 0.6996.


GlobalSantaFe Options, SARs and Restricted Stock Units and Assumption of GlobalSantaFe Stock Plans

        Except as described below, the GlobalSantaFe options and stock-settled stock appreciation rights, or GlobalSantaFe SARs, and the relevant GlobalSantaFe stock plans, as in effect at the effective time of the Merger, will remain in effect and be assumed by Transocean.

        All options to acquire GlobalSantaFe ordinary shares that were granted under GlobalSantaFe stock plans will remain outstanding following the effective time of the Merger, subject to certain modifications, as described below. Prior to the effective time of the Merger, Transocean and GlobalSantaFe will take all actions required to permit the assumption of such GlobalSantaFe options by Transocean. Each GlobalSantaFe option assumed by Transocean will, to the extent provided by the applicable governing instruments, and to the extent not already fully vested and exercisable, be fully vested and exercisable as of the effective time of the Merger and will otherwise be subject to the same terms and conditions as under the applicable governing instruments except that immediately following the effective time of the Merger:

In addition, GlobalSantaFe options that would otherwise expire under their terms will be deemed modified to remain exercisable for their full scheduled term in the event the holder of any such

93



GlobalSantaFe option is involuntarily terminated for any reason other than cause within twelve months after the effective time of the Merger.

        For purposes of the foregoing, the "GlobalSantaFe Adjustment Fraction" means (1) the VWAP of the GlobalSantaFe ordinary shares on the last trading day immediately preceding the closing date of the Transactions, divided by (2) the Post-Closing Transocean Ordinary Share Fair Market Value.

        At the effective time of the Merger, all GlobalSantaFe stock-settled SARs outstanding at the effective time of the Merger under the GlobalSantaFe stock plans will remain outstanding following the effective time of the Merger, subject to certain modifications, as described below. Prior to the effective time of the Merger, GlobalSantaFe and Transocean will take all actions required to permit the assumption of the GlobalSantaFe SARs by Transocean. Each GlobalSantaFe SAR assumed by Transocean will, to the extent provided by the applicable governing instruments, and to the extent not already fully vested and exercisable, be fully vested and exercisable as of the effective time of the Merger and will otherwise be subject to the same terms and conditions as under the applicable governing instrument, except that immediately following the effective time:

In addition, GlobalSantaFe SARs that would otherwise expire under their terms will be deemed modified to remain exercisable for their full scheduled term in the event the holder of any such GlobalSantaFe SAR is involuntarily terminated for any reason other than cause within twelve months after the effective time of the Merger.

        Each restricted stock unit with respect to GlobalSantaFe ordinary shares outstanding immediately prior to the effective time of the Merger under the GlobalSantaFe stock plans will, as of the effective time of the Merger, be converted into and exchanged for the GlobalSantaFe merger consideration.

94



Treatment of Transocean Warrants and Convertible Debentures

        As of July 31, 2007, warrants to purchase 2,706,550 Transocean ordinary shares at an exercise price of $19 per share were outstanding. The warrant agreement for these warrants provides that, as a result of the Reclassification, the warrants become exercisable for 0.6996 Transocean ordinary shares for each Transocean ordinary share the warrants were previously exercisable at an adjusted exercise price equal to an amount determined pursuant to specified formulas in Sections 17(a) and (c) of the warrant agreement. Transocean believes that the adjustment of the number of Transocean ordinary shares for which the warrants are exercisable and the exercise price pursuant to the warrant agreement will not allow holders to receive the full economic benefit of the Reclassification. In order to place the warrantholders in a position more comparable to that of ordinary shareholders, Transocean currently intends to allow warrantholders to receive upon exercise following the Reclassification 0.6996 Transocean ordinary shares and $33.03 (i.e., the same consideration that a warrantholder would have owned immediately after the Reclassification if the warrantholder had exercised its warrant immediately before the Reclassification) for each Transocean ordinary share for which the warrants were previously exercisable, at an exercise price of $19 per Transocean ordinary share for which the warrants were exercisable prior to the Reclassification.

        Prior to consummation of the Transactions, Transocean currently expects to call for redemption its Zero Coupon Convertible Debentures due May 2020 and its 1.5% Convertible Debentures due 2021. If not so redeemed, in accordance with the indentures governing the Zero Coupon Convertible Debentures and the 1.5% Convertible Debentures, as a result of the Reclassification, the debentures will become convertible into 0.6996 Transocean ordinary shares and $33.03 for each Transocean ordinary share for which the debentures were previously convertible.


Dividend Policy

        Transocean does not generally pay cash dividends. Any future declaration and payment of any cash dividends following the completion of the Transactions will (1) depend on Transocean's results of operations, financial condition, cash requirements and other relevant factors, (2) be subject to the discretion of Transocean's board of directors, (3) be subject to restrictions contained in the bridge loan facility and other debt covenants of the combined company and (4) be payable only out of Transocean's profits or share premium account in accordance with Cayman Islands law.


Accounting Treatment and Considerations

        Transocean will account for the Reclassification as a reverse stock split and dividend and will account for the Merger using the purchase method of accounting with Transocean treated as the acquiror. Because of the accounting treatment for the Reclassification, any comparison of estimated or actual earnings per share for 2008 and 2009 to prior periods of Transocean will be affected by the required restatement of prior period earnings per share after the Reclassification in accordance with U.S. GAAP.

        As the accounting acquiror, Transocean's assets and liabilities will remain at historical amounts. In applying purchase accounting, Transocean will record the assets and liabilities of GlobalSantaFe at their estimated fair values at the closing date of the Transactions with the excess of the purchase price over the sum of such fair values recorded as goodwill. For purposes of the pro forma financial statements, the $17.5 billion purchase price is calculated using the estimated number of Transocean ordinary shares to be issued in the Merger and a $113.11 per share average trading price of Transocean ordinary shares for a period of time immediately before and after the Transactions were announced, plus estimated cash consideration to be paid to GlobalSantaFe shareholders based on the number of GlobalSantaFe ordinary shares estimated to be outstanding at the time of the Merger and cash consideration of $22.46 per share plus estimated direct Merger costs and expenses and the estimated fair value of

95



GlobalSantaFe stock options and share appreciation rights to be assumed by Transocean. 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 completion of the Merger or the value of the Transocean ordinary shares to be received by holders of ordinary shares of GlobalSantaFe in connection with the Merger or by holders of Transocean ordinary shares in connection with the Reclassification.

        The estimated $9.6 billion cash payment, which is characterized as a dividend for accounting purposes, to Transocean shareholders is calculated based on the number of Transocean ordinary shares estimated to be outstanding at the time of the Reclassification.


Accretion and Dilution Considerations

        As indicated in "The Transactions—Opinion of Goldman, Sachs & Co.—Accretion/Dilution Analysis," Transocean management's estimated earnings per share and cash flow per share of the combined company for 2008 and 2009 (as provided to Goldman Sachs in July 2007 for purposes of its opinion) after the Transactions exceeded the estimated earnings per share and cash flow per share of Transocean on a standalone basis (assuming no Transactions are completed). Similarly, as indicated in "The Transactions—Opinion of Lehman Brothers Inc.," the Lehman Brothers pro forma merger model provides that for the combined company, the estimated 2008 and 2009 cash flow per share and earnings exceeded the estimated cash flow per share and earnings of Transocean on a standalone basis (assuming no Transactions are completed). If the standalone estimated 2008 and 2009 earnings per share are adjusted to reflect the reverse stock split in a similar fashion to how historical earnings per share will be adjusted for U.S. GAAP, then the Transactions would be dilutive to both estimated earnings and cash flow per share. Without the Reclassification, the Merger by itself would be accretive to such estimated earnings and cash flow per share in 2008 and 2009.


Material U.S. Federal Income Tax Consequences

Scope of Discussion

        The following discussion summarizes the material U.S. federal income tax consequences of (1) the Reclassification to U.S. holders and non-U.S. holders (as defined below) of Transocean ordinary shares, (2) the Merger to U.S. holders and non-U.S. holders of GlobalSantaFe ordinary shares, and (3) the subsequent ownership and disposition of Transocean ordinary shares.

        This discussion is based upon the Internal Revenue Code of 1986, as amended, Treasury Regulations promulgated under the Internal Revenue Code, court decisions, published positions of the Internal Revenue Service and other applicable authorities, all as in effect on the date of this document and all of which are subject to change or differing interpretations, possibly with retroactive effect. This discussion is limited to holders who hold Transocean ordinary shares or GlobalSantaFe ordinary shares, and who will after the Reclassification and the Merger hold Transocean ordinary shares, as capital assets for U.S. federal income tax purposes (generally, assets held for investment). This discussion does not address all of the U.S. federal income tax consequences that may be relevant to holders in light of their particular circumstances or to holders who may be subject to special treatment under U.S. federal income tax laws, such as:

96


97


        Moreover, this discussion does not address any aspect of non-income taxation or state, local or foreign taxation. No ruling has been or will be obtained from the Internal Revenue Service regarding the Reclassification or the Merger. While receipt of opinions of counsel on certain tax consequences of the Reclassification and the Merger are conditions to the closing of the Transactions, an opinion of counsel is not a guarantee of a result, since such an opinion merely represents counsel's best legal judgment and is not binding on the Internal Revenue Service or the courts. In addition, the parties have not received and do not expect to receive opinions of counsel except as specifically described below. As a result, no assurance can be given that the Internal Revenue Service will not assert, or that a court will not sustain, a position contrary to any of the conclusions set forth below.

        As used in this summary, a "U.S. holder" is a beneficial owner of Transocean ordinary shares or GlobalSantaFe ordinary shares who for U.S. federal income tax purposes is:

        A "non-U.S. holder" of Transocean ordinary shares or GlobalSantaFe ordinary shares is a holder, other than an entity or arrangement treated as a partnership for U.S. federal income tax purposes, that is not a U.S. holder. For purposes of this summary, "holder" or "shareholder" means either a U.S. holder or a non-U.S. holder or both, as the context may require.

        If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of Transocean ordinary shares or GlobalSantaFe ordinary shares, the tax treatment of a partner in that partnership will generally depend on the status of the partner and the activities of the partnership. Holders of Transocean ordinary shares or GlobalSantaFe ordinary shares that are partnerships and partners in these partnerships are urged to consult their tax advisers regarding the U.S. federal income tax consequences to them of the Reclassification or the Merger.

        THIS SUMMARY IS NOT A SUBSTITUTE FOR AN INDIVIDUAL ANALYSIS OF THE TAX CONSEQUENCES OF THE RECLASSIFICATION OR THE MERGER TO YOU. WE URGE YOU TO CONSULT A TAX ADVISER REGARDING THE PARTICULAR FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE RECLASSIFICATION OR THE MERGER IN LIGHT OF YOUR OWN SITUATION.

98


Opinions of Counsel

        It is a condition to the obligation of Transocean to close the Reclassification and the Merger that it shall have received the opinion of its counsel, Baker Botts L.L.P., effective as of the date of the closing of the Transactions, that (1) Transocean shareholders will recognize no income or gain in the Reclassification except with respect to cash received in the Reclassification and (2) the Merger will be treated as a reorganization qualifying under section 368(a) of the Internal Revenue Code. It is a condition to the obligation of GlobalSantaFe to close the Merger that it shall have received the opinion of its counsel, Skadden, Arps, Slate, Meagher & Flom LLP, effective as of the date of the closing of the Transactions, that the Merger will be treated as a reorganization qualifying under section 368(a) of the Internal Revenue Code.

        The opinions of counsel may state that the conclusions expressed therein are not entirely free from doubt and may include other qualifications and limitations as expressed therein. These opinions are and will be based on U.S. federal income tax law in effect as of the date of the opinions. In rendering their opinions, Baker Botts L.L.P. and Skadden, Arps, Slate, Meagher & Flom LLP will rely on certain assumptions, including assumptions regarding the absence of changes in existing facts and the completion of the Reclassification and the Merger strictly in accordance with the merger agreement and this joint proxy statement. Counsel will also rely upon certain representations and covenants in the merger agreement as well as representation letters provided by Transocean and GlobalSantaFe and will assume that these representations are true, correct and complete without regard to any knowledge limitation and that these covenants will be complied with. If any of these assumptions or representations are inaccurate in any way, or any of the covenants are not complied with, the opinions could be adversely affected. In addition, counsel will rely upon the opinions of Cayman Islands counsel as to certain matters of Cayman Islands law.

        In the remainder of this discussion, except as otherwise indicated, it is assumed that the opinions of counsel described above will be delivered at closing and that, notwithstanding any qualifications or limitations in the opinions, (1) Transocean shareholders will recognize no income or gain in the Reclassification except with respect to cash received in the Reclassification and (2) the Merger will be treated as a reorganization qualifying under section 368(a) of the Internal Revenue Code.

The Reclassification

        The following is a discussion of the material U.S. federal income tax consequences to the holders of Transocean ordinary shares of the Reclassification and, in the case of non-U.S holders, of the subsequent ownership and disposition of the Transocean ordinary shares. The discussion is subject to the assumptions and limitations set forth above in "Material U.S. Federal Income Tax Consequences—Scope of Discussion."

        Transocean expects that the cash paid by Transocean to its shareholders in the Reclassification will be treated as paid in redemption of a pro rata portion of their Transocean ordinary shares (i.e., 30.04%, which represents the portion of each Transocean ordinary share which, under the merger agreement, is to be exchanged for cash). Transocean presently intends to so treat the Reclassification for relevant reporting purposes. However, it is possible that the Internal Revenue Service will successfully assert that the Reclassification should be treated as a recapitalization under section 368(a)(1)(E) of the Internal Revenue Code. The differences between treatment as a redemption and as a recapitalization are as described below.

        Treatment of the Reclassification as a Redemption.    If the cash delivered in the Reclassification is treated as received in a redemption, then a U.S. holder of Transocean ordinary shares will recognize

99



capital gain or loss equal to the difference between the cash received from Transocean and the adjusted tax basis of the shares considered to be redeemed, if any of the following tests is satisfied:

        These tests are prescribed by section 302 of the Internal Revenue Code and will sometimes be referred to as the "section 302 tests."

        Gain or loss will be computed separately with respect to each identified block (that is, stock acquired at the same time for the same price) of Transocean ordinary shares redeemed. Capital gain or loss of a U.S. holder generally will be long-term capital gain or loss if the Transocean ordinary shares have been held by the U.S. holder for more than one year. Under current law, long-term capital gain of non-corporate U.S. holders is subject to tax at a maximum rate of 15%. There are limitations on the deductibility of capital losses.

        Each of the section 302 tests requires, in one manner or another, that a shareholder's proportionate interest in Transocean (i.e., the percentage of Transocean ordinary shares that the shareholder owns) be reduced by the redemption. Dispositions or acquisitions of Transocean ordinary shares which are contemporaneous with the Reclassification and the Merger may be deemed to be part of a single integrated transaction with the Reclassification and the Merger and may be taken into account in determining whether any of the section 302 tests has been satisfied.

        In applying the section 302 tests, U.S. holders must take into account not only the Transocean ordinary shares that they actually own but also any Transocean ordinary shares they are treated as owning under the constructive ownership rules described in section 318 of the Internal Revenue Code (as modified by section 302(c)). Under the constructive ownership rules, a shareholder is treated as constructively owning any Transocean ordinary shares that are owned by certain related individuals or entities and any Transocean ordinary shares that the shareholder has the right to acquire by exercise of an option or by conversion or exchange of a security. In the remainder of this discussion, references to ownership of stock include constructive as well as actual ownership.

        Under the "substantially disproportionate" test, the percentage of Transocean ordinary shares which the shareholder owns after the redemption must be less than 80% of the percentage of the Transocean ordinary shares owned by the shareholder immediately before the redemption. Under the "not essentially equivalent to a dividend" test, the reduction in the shareholder's interest in Transocean in the redemption must be a "meaningful reduction" in light of the shareholder's particular facts and circumstances. The Internal Revenue Service has indicated that even a small reduction in the interest of a minority shareholder that owns a small number of shares in a publicly and widely held corporation and that exercises no control over corporate affairs would be a meaningful reduction for this purpose.

        Under the merger agreement, the Reclassification will occur immediately before the Merger. While the matter is not free from doubt, Transocean expects that the "substantially disproportionate" test and the "not essentially equivalent to a dividend" test will be applied by comparing a shareholder's proportionate interest in Transocean before the Reclassification with the shareholder's proportionate interest in Transocean after the Merger.

        If this is correct, then a Transocean shareholder who owns no GlobalSantaFe shares at the time of the Reclassification and the Merger should generally satisfy the "substantially disproportionate" test. In addition, if the tests are so applied, a shareholder who does own GlobalSantaFe shares but in a lesser proportionate amount than the shareholder's ownership of Transocean shares may be able to satisfy the "not essentially equivalent to a dividend" test.

100



        It is possible that the "substantially disproportionate" and "not essentially equivalent to a dividend" tests will be applied in a different manner than that just described. In this event, Transocean shareholders may not generally satisfy either such test.

        A Transocean shareholder may be able to satisfy the "complete termination" test if the shareholder sells or otherwise disposes of all of the shareholder's Transocean ordinary shares for cash contemporaneously with the completion of the Reclassification and as part of a plan which includes participation by the shareholder in the Reclassification. However, there is some uncertainty as to whether the "complete termination" test applies in such circumstances. Shareholders should consult their own tax advisers as to this matter in light of their specific circumstances and the applicable law.

        If none of the section 302 tests is satisfied, no loss will be recognized, and the entire amount of cash received by the shareholder from Transocean will be treated as the distribution of a dividend, to the extent of Transocean's current and accumulated earnings and profits, then as a tax-free return of capital to the extent of the allowable basis recovery, as discussed below, and then as capital gain. The accumulated earnings and profits of Transocean for this purpose may be increased by part or all of the accumulated earnings and profits of GlobalSantaFe at the time of the Merger.

        The amount treated as a dividend which is received by a non-corporate shareholder will generally be subject to U.S. federal income tax at a maximum rate of 15%, provided certain holding period requirements are met. The amount treated as a dividend which is received by a corporate shareholder will not be eligible for the dividends received deduction which is generally allowed to U.S. corporate shareholders on dividends received from a domestic corporation, except to the extent that such dividend is treated as having been paid out of earnings and profits accumulated by a U.S. predecessor of Transocean.

        As indicated, if none of the section 302 tests is satisfied, the cash received by a Transocean shareholder which is in excess of the amount treated as a dividend will be treated as a tax-free return of capital to the extent of the allowable basis recovery. In comparable circumstances, the Internal Revenue Service has stated that the better view of current law is that only the basis of the shares redeemed (as opposed to the shareholder's basis in all of the shareholder's Transocean ordinary shares) may be recovered but that the Internal Revenue Service is considering other approaches.

        Special rules not here described may apply to shareholders who do not have a uniform basis and holding period in all of their Transocean ordinary shares and to U.S. corporate shareholders, as to which any dividend which is treated as having been paid out of earnings and profits accumulated by a U.S. predecessor of Transocean might be treated as an "extraordinary dividend" under section 1059 of the Internal Revenue Code. Shareholders in these circumstances should consult their own tax advisers as to the particular tax consequences to them if none of the section 302 tests is satisfied.

        Certain U.S. holders of Transocean ordinary shares may be subject to backup withholding (currently at a rate of 28%) on cash received pursuant to the Reclassification. Backup withholding will not apply, however, to a holder of Transocean ordinary shares who provides a correct taxpayer identification number or comes within certain exempt categories and complies with applicable certification requirements. In addition to being subject to backup withholding, if a U.S. holder of Transocean ordinary shares does not provide Transocean (or the exchange agent) with the holder's correct taxpayer identification number or other required information, the holder may be subject to penalties imposed by the Internal Revenue Service. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against the holder's U.S. federal income tax liability, provided that the holder furnishes certain required information to the Internal Revenue Service.

        Treatment of the Reclassification as a Recapitalization.    As indicated, while Transocean expects that the Reclassification will be treated as a redemption of a pro rata portion of the Transocean ordinary

101



shares, it is possible that the Reclassification will be treated as a recapitalization under section 368(a)(1)(E) of the Internal Revenue Code. In this event, Transocean shareholders would be treated as receiving new Transocean ordinary shares and cash in exchange for their existing Transocean ordinary shares.

        If the Reclassification were treated as a recapitalization for U.S. federal income tax purposes, each Transocean shareholder would recognize gain, but not loss, on the exchange in an amount equal to the lesser of:

        Any such gain would be capital gain provided that one of the section 302 tests described above was satisfied. The section 302 tests would generally be applied in the manner described above. See "—Treatment of the Reclassification as a Redemption."

        Capital gain generally would be long-term capital gain if the Transocean ordinary shares have been held by the shareholder for more than one year. Under current law, long-term capital gain of non-corporate shareholders is subject to tax at a maximum rate of 15%.

        If none of the section 302 tests were satisfied, the shareholder's gain would be treated as the distribution of a dividend to the extent of the shareholder's ratable share of Transocean's available earnings and profits and then as capital gain. The available earnings and profits of Transocean for this purpose may be increased by part or all of the available earnings and profits of GlobalSantaFe at the time of the Merger. The amount treated as a dividend which was received by a non-corporate shareholder would generally be subject to U.S. federal income tax at a maximum rate of 15%, provided certain holding period requirements were met.

        The amount treated as a dividend which was received by a corporate shareholder would not be eligible for the dividends received deduction which is generally allowed to U.S. corporate shareholders on dividends received from a domestic corporation, except to the extent that such amount was treated as having been paid out of earnings and profits accumulated by a U.S. predecessor of Transocean. The amount treated as a dividend, if any, which was treated as having been paid out of earnings and profits accumulated by a U.S. predecessor of Transocean in some cases may be an "extraordinary dividend" under section 1059 of the Internal Revenue Code. U.S. corporate shareholders should consult their own tax advisers as to these matters.

        The aggregate tax basis of the new Transocean ordinary shares treated as having been received by a U.S. holder in the Reclassification (excluding the basis in any Transocean fractional ordinary share) would be the same as the aggregate tax basis of the Transocean ordinary shares held immediately before the recapitalization (excluding any basis allocable to a fractional share), decreased by the amount of cash received (excluding any cash received in lieu of a fractional share) and increased by the amount of gain recognized in the Reclassification (including gain treated as dividend income but excluding any gain recognized as a result of cash received in lieu of a fractional share).

        The holding period of the Transocean ordinary shares treated as having been received by a Transocean shareholder pursuant to the Reclassification would include the holding period of the

102



Transocean ordinary shares held immediately before the Reclassification. Transocean shareholders who hold Transocean ordinary shares with differing bases or holding periods are urged to consult their tax advisers with regard to identifying the bases or holding periods of the particular Transocean ordinary shares received in the Reclassification in the event the Reclassification were treated as a recapitalization.

        If the Reclassification were treated as a recapitalization and a shareholder received cash in lieu of a fractional Transocean ordinary share, the holder would generally recognize capital gain or loss in an amount equal to the difference between the cash so received and the portion of the holder's adjusted tax basis in the Transocean ordinary shares that was allocable to the fractional share. The capital gain or loss would be long-term capital gain or loss if the holding period for the fractional share is more than one year as of the date of the Reclassification.

        A non-U.S. holder of Transocean ordinary shares will not be subject to U.S. federal income or withholding tax on any gain or dividend income with respect to the Reclassification and will not be subject to U.S. federal income or withholding tax on any gain recognized on a subsequent disposition of Transocean ordinary shares held after the Reclassification or on dividends paid on such shares, unless:

        In order not to be subject to backup withholding tax on cash received in connection with the Reclassification, a subsequent disposition of Transocean ordinary shares, or dividends paid on those shares, a non-U.S. holder may be required to provide a taxpayer identification number, certify the holder's foreign status or otherwise establish an exemption.

The Merger

        The following is a discussion of the material U.S. federal income tax consequences to the holders of GlobalSantaFe ordinary shares on the exchange in the Merger of GlobalSantaFe ordinary shares for Transocean ordinary shares and cash and, in the case of non-U.S. holders, of holding and disposing of Transocean ordinary shares received in such exchange. The discussion is subject to the assumptions and limitations set forth above in "Material U.S. Federal Income Tax Consequences—Scope of Discussion."

        Assuming the Merger qualifies as a "reorganization" within the meaning of section 368(a) of the Internal Revenue Code, the material U.S. federal income tax consequences of the Merger to a U.S. holder of GlobalSantaFe ordinary shares are as follows:

        A U.S. holder of GlobalSantaFe ordinary shares will generally recognize gain (but not loss) in the Merger. Any gain recognized will equal the lesser of:

103


        Gain recognized upon the exchange generally will be capital gain, unless the receipt of cash by a U.S. holder has the effect of a distribution of a dividend. If the receipt of cash has the effect of the distribution of a dividend, the gain will be treated as dividend income to the extent of the U.S. holder's ratable share of available earnings and profits as calculated for U.S. federal income tax purposes. While the matter is not clear, the better reasoned view is that, for this purpose, available earnings and profits will include only the available earnings and profits of GlobalSantaFe at the time of the Merger and will not include any earnings and profits of Transocean.

        For purposes of determining whether the receipt of cash has the effect of a distribution of a dividend, a GlobalSantaFe shareholder will be treated as if the shareholder exchanged all of the shareholder's GlobalSantaFe ordinary shares solely for Transocean ordinary shares and then received cash in the amount actually paid to the shareholder in redemption of a portion of the Transocean ordinary shares. The section 302 tests described above will then be applied to determine whether the shareholder has experienced a qualifying reduction in interest in Transocean. See "—The Reclassification—U.S. Holders of Transocean Ordinary Shares—Treatment of the Reclassification as a Redemption."

        Certain constructive ownership rules must be taken into account for this purpose. In the remainder of this discussion, references to ownership of stock include constructive as well as actual ownership.

        GlobalSantaFe believes that a U.S. holder of its ordinary shares who does not, immediately prior to the Merger, own any Transocean ordinary shares should qualify under the "substantially disproportionate" test described above. This conclusion, however, is not free from doubt. U.S. holders are urged to consult their tax advisers about the possibility that all or a portion of any cash received in exchange for GlobalSantaFe ordinary shares will be treated as a dividend.

        Any recognized capital gain will be long-term capital gain if the U.S. holder has held the GlobalSantaFe ordinary shares for more than one year. Under current law, long-term capital gain of non-corporate shareholders is subject to tax at a maximum rate of 15%.

        Any gain of a non-corporate holder which is treated as dividend income will generally be subject to U.S. federal income tax at a maximum rate of 15%, provided certain holding period requirements are met. Any gain of a corporate holder which is treated as dividend income will not be eligible for the dividends received deduction which is generally allowed to U.S. corporate shareholders on dividends received from a domestic corporation.

        If a U.S. holder of GlobalSantaFe ordinary shares receives cash in lieu of a fractional Transocean ordinary share, the holder will generally recognize capital gain or loss equal to the difference between the cash so received and the portion of the holder's adjusted tax basis in the GlobalSantaFe ordinary shares that is allocable to this fractional share. The capital gain or loss will be long-term capital gain or loss if the holding period for the fractional share is more than one year as of the date of the Merger.

        The aggregate tax basis of the Transocean ordinary shares received by a U.S. holder of GlobalSantaFe ordinary shares in the Merger (excluding the basis in any fractional share) will be the same as the aggregate tax basis of the GlobalSantaFe ordinary shares exchanged in the Merger (excluding any basis allocable to a fractional share), decreased by the amount of cash received

104



(excluding any cash received in lieu of a fractional share) and increased by the amount of gain recognized in the Merger (including gain treated as dividend income but excluding any gain recognized as a result of cash received in lieu of a fractional share).

        The holding period of the Transocean ordinary shares received by a GlobalSantaFe shareholder pursuant to the Merger will include the holding period of the GlobalSantaFe ordinary shares surrendered in the Merger. GlobalSantaFe shareholders who hold GlobalSantaFe ordinary shares with differing bases or holding periods are urged to consult their tax advisers with regard to identifying the bases or holding periods of the particular Transocean ordinary shares received in the Merger.

        Special rules not here described apply to any U.S. holder of GlobalSantaFe ordinary shares who, immediately after the Merger, actually and constructively owns at least 5% of the Transocean ordinary shares. Any such shareholder should consult the shareholder's own tax adviser concerning the treatment of the shareholder in the Merger, including the possibility of filing a "gain recognition agreement" under applicable Treasury regulations.

        Certain U.S. holders of GlobalSantaFe ordinary shares may be subject to backup withholding (currently at a rate of 28%) on cash received pursuant to the Merger. Backup withholding will not apply, however, to a holder of GlobalSantaFe ordinary shares who provides a correct taxpayer identification number or comes within certain exempt categories and complies with applicable certification requirements. In addition to being subject to backup withholding, if a U.S. holder of GlobalSantaFe ordinary shares does not provide Transocean (or the exchange agent) with the holder's correct taxpayer identification number or other required information, the holder may be subject to penalties imposed by the Internal Revenue Service. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against the holder's U.S. federal income tax liability, provided that the holder furnishes certain required information to the Internal Revenue Service.

        A non-U.S. holder of GlobalSantaFe ordinary shares will not be subject to U.S. federal income or withholding tax on any gain or dividend income with respect to the Merger and will not be subject to U.S. federal income or withholding tax on any gain recognized on a subsequent disposition of Transocean ordinary shares received in the Merger or on dividends paid on such shares, unless:


        In order not to be subject to backup withholding tax on cash received in connection with the Merger, a subsequent disposition of Transocean ordinary shares, or dividends paid on those shares, a non-U.S. holder may be required to provide a taxpayer identification number, certify the holder's foreign status or otherwise establish an exemption.

        If the Merger were not treated as a "reorganization" within the meaning of section 368(a) of the Internal Revenue Code, then (1) each U.S. holder of GlobalSantaFe ordinary shares would recognize capital gain or loss equal to the difference between the sum of the fair market value of the Transocean

105


ordinary shares and the amount of cash received in the Merger (including cash received in lieu of a fractional Transocean ordinary share) and the shareholder's adjusted tax basis in the GlobalSantaFe ordinary shares surrendered in exchange therefor and (2) each non-U.S. holder of GlobalSantaFe ordinary shares generally would not be subject to U.S. federal income tax on any gain recognized, subject to the exceptions set forth above under the heading "—Non-U.S. Holders of GlobalSantaFe Ordinary Shares."

Subsequent Ownership and Disposition of Transocean Ordinary Shares

        The following is a discussion of the material U.S. federal income tax consequences to U.S. holders of Transocean ordinary shares and GlobalSantaFe ordinary shares of the ownership and disposition of Transocean ordinary shares after the Reclassification and the Merger. The discussion is subject to the assumptions and limitations set forth above in "Material U.S. Federal Income Tax Consequences—Scope of Discussion."

        The following discussion of distributions and sale of Transocean ordinary shares is subject to the discussion in the section below which is entitled "Special Status of Certain Corporations for U.S. Tax Purposes."

        U.S. holders of Transocean ordinary shares will be required to include in gross income as ordinary income the gross amount of any distribution on the Transocean ordinary shares, to the extent that the distribution is paid out of Transocean's current or accumulated earnings and profits as determined for U.S. tax purposes (a "dividend"). Under current law, dividends received by a non-corporate shareholder will generally be subject to U.S. federal income tax at a maximum rate of 15%, provided certain holding period requirements are met. However, this reduced rate is scheduled to expire effective for taxable years beginning after December 31, 2010. In addition, from time to time, legislation has been proposed that would impose certain conditions on the availability of the reduced rate, which conditions Transocean would not expect to meet. Dividends received by a corporate shareholder will not be eligible for the dividends received deduction which is generally allowed to U.S. corporate shareholders on dividends received from a domestic corporation, except to the extent that such dividend is treated as having been paid out of earnings and profits accumulated by a U.S. predecessor of Transocean.

        Distributions in excess of current and accumulated earnings and profits will be applied first to reduce the tax basis of the U.S. holder of Transocean ordinary shares in such holder's shares. To the extent that the distribution exceeds the holder's tax basis, the excess will constitute gain from a sale or exchange of the shares.

        Under current law, long-term capital gain of non-corporate shareholders is subject to tax at a maximum rate of 15%. However, this reduced rate is scheduled to expire effective for taxable years beginning after December 31, 2010. There are limitations on the deductibility of capital losses.

        Transocean expects that, for foreign tax credit purposes, dividends paid on the Transocean ordinary shares will generally be foreign source income and will generally be "passive category income." Under section 904(h) of the Internal Revenue Code, however, dividends paid by a foreign corporation that is treated as more than 50% owned by U.S. persons may be treated as U.S. source income for foreign tax credit purposes, to the extent that the foreign corporation itself has more than an insignificant amount of U.S. source income. It is possible that a portion of the dividends paid by Transocean could be treated as U.S. source income under section 904(h) of the Internal Revenue Code.

        A U.S. holder of Transocean ordinary shares will generally recognize gain or loss for U.S. tax purposes upon the sale or exchange of such shares in an amount equal to the difference between the

106



amount realized from such sale or exchange and the holder's tax basis in such shares. Such gain or loss will be capital gain or loss and, in the case of a non-corporate U.S. holder of Transocean ordinary shares, any such long-term capital gain would under current law be subject to reduced rates of taxation.

        Dividends on Transocean ordinary shares paid within the United States or through certain U.S.-related financial intermediaries are subject to information reporting and may be subject to backup withholding (currently at a 28% rate) unless the holder (1) is a corporation or other exempt recipient or (2) provides a taxpayer identification number and satisfies certain certification requirements. Information reporting requirements and backup withholding may also apply to the cash proceeds of a sale of the Transocean ordinary shares. Backup withholding is not an additional tax. Amounts withheld under the backup withholding rules may be credited against a U.S. holder's U.S. tax liability, and a holder may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the Internal Revenue Service.

        For U.S. tax purposes, a foreign corporation, such as Transocean, is classified as a passive foreign investment company for each taxable year in which either (1) 75% or more of its gross income is passive income (as defined for U.S. tax purposes) or (2) on average for such taxable year, 50% or more in value of its assets produce passive income or are held for the production of passive income. For purposes of applying the tests in the preceding sentence, the foreign corporation is deemed to own its proportionate share of the assets of and to receive directly its proportionate share of the income of any other corporation of which the foreign corporation owns, directly or indirectly, at least 25% by value of the stock.

        Classification of a foreign corporation as a passive foreign investment company can have various adverse consequences to shareholders of the corporation who are U.S. persons. These include taxation of gain on a sale or other disposition of the shares of the corporation at ordinary income rates and imposition of an interest charge on gain or on distributions with respect to the shares.

        Transocean believes that it will not be a passive foreign investment company following the Merger. However, the tests for determining passive foreign investment company status are applied annually, and it is difficult accurately to predict future income and assets relevant to this determination. Accordingly, Transocean cannot assure U.S. holders of Transocean ordinary shares that it will not become a passive foreign investment company.

        If Transocean should determine in the future that it is a passive foreign investment company, it will endeavor to so notify U.S. holders of Transocean ordinary shares, although there can be no assurance that it will be able to do so in a timely and complete manner. U.S. holders of Transocean ordinary shares should consult their own tax advisers about the passive foreign investment company rules, including the availability of certain elections.


Amendment and Restatement of Transocean's Memorandum of Association and Articles of Association

General

        The board of directors of Transocean has unanimously adopted a resolution to submit to a vote of its shareholders a proposal to amend and restate its memorandum of association and articles of association to, among other things, increase the maximum number of directors constituting the board of directors of Transocean from 13 to 14, to provide for certain corporate governance provisions described below, and make certain updating changes described below.

107



Purpose of Increasing the Number of Directors and the Corporate Governance Provisions

        There are currently 12 directors serving on Transocean's board of directors. The maximum number of directors under Transocean's charter documents is 13. If this proposal is approved by Transocean's shareholders, the maximum number of directors would increase from 13 to 14. The merger agreement provides that the board of directors of Transocean at the effective time of the Merger will be comprised of 14 directors, seven of whom will be designated by Transocean and seven of whom will be designated by GlobalSantaFe.

        The merger agreement also stipulates that Transocean's amended and restated memorandum of association and articles of association will provide for the following corporate governance provisions during the two-year period following the completion of the Transactions:

In addition, the foregoing provisions may not be amended unless such amendment was first approved by the vote of two-thirds of the entire board of directors.

Purpose of the Updating Changes

        The purpose of the updating changes is the addition of provisions (1) for uncertificated shares, (2) for the electronic transmission of proxies and (3) clarifying the role and duties of the Chief Executive Officer and the President.

108


Vote Required; Recommendation of the Board of Directors

        Approval of this proposal requires the vote of at least two-thirds of the votes of Transocean shareholders cast on the proposal. Approval of this proposal is a condition to the completion of the Transactions. If approved, the proposal will be implemented only if the Transactions are completed.

        For the reasons described above, Transocean's board of directors unanimously recommends that the Transocean shareholders vote "FOR" the proposal to amend and restate Transocean's memorandum of association and articles of association.


Regulatory Matters

        Transocean and GlobalSantaFe must make filings and receive authorizations from various governmental agencies, both in the United States and internationally, to complete the Transactions. These filings, notifications and clearances relate primarily to antitrust and securities laws. Transocean and GlobalSantaFe intend to pursue vigorously all required regulatory clearances. Although the required clearances have not yet been received, Transocean and GlobalSantaFe estimate that they will receive regulatory clearances sufficient to complete the Transactions by the end of 2007. However, the Transactions may not be completed until some time in 2008. Neither Transocean nor GlobalSantaFe can assure you that it will obtain all required clearances by the time of its shareholder meeting or at all. In addition, neither Transocean nor GlobalSantaFe can assure you that governmental authorities will not impose unfavorable conditions for granting the required clearances.

        Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"), the parties cannot complete the Merger until they have notified and furnished 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. Transocean and GlobalSantaFe have made their filing under the HSR Act.

        Each other country and U.S. state in which Transocean or GlobalSantaFe has operations also may review the Merger under its antitrust laws. The parties have informally notified the U.K. competition authorities of their intent to enter into the Merger, and intend to furnish information to the U.K. authorities regarding the transaction and the relevant economic circumstances. A competition/antitrust filing has also been 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 prevent the Merger or to cause Transocean or GlobalSantaFe to divest assets or businesses as a condition to completing the Merger. Neither Transocean nor GlobalSantaFe can assure you that a challenge to the Merger will not be made or, if a challenge is made, that Transocean or GlobalSantaFe will prevail.

        Furthermore, any of the relevant governmental authorities or a private person or entity could seek, under antitrust laws, to take action against Transocean or GlobalSantaFe after the completion of the Merger. Transocean and GlobalSantaFe are unable to predict whether any action will be taken or what the outcome of any action may be.

        The parties' obligation to complete the Transactions is subject to the condition that no decree, order or injunction of a court of competent jurisdiction prohibits the completion of the Merger or the Reclassification. The parties agreed, however, that before invoking this condition, they will comply with the provisions described in the following paragraph. The parties agreed in all other cases to use reasonable best efforts to have the decree, order or injunction lifted or vacated before invoking the condition. The parties also conditioned the completion of the Transactions on the following:

109


        Under the merger agreement, the parties agreed to use their reasonable 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 reasonable best efforts to make or seek all material filings and consents to the Merger 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 reasonable best efforts to take any and all steps necessary to gain any consents to completing the Merger or to eliminate any impediments to the Merger. Under the merger agreement, neither Transocean nor GlobalSantaFe is required to dispose of any assets or consent to the disposition of the other's assets, limit its freedom of action with respect to any of its businesses or consent to such disposition or limits, unless the action to be taken, in the reasonable good faith judgment of both Transocean and GlobalSantaFe, does not and is not reasonably likely to have a material adverse effect on Transocean or GlobalSantaFe, materially impair the benefits or advantages either Transocean or GlobalSantaFe expects to receive from the Transactions, or have a material adverse effect on the business plan or the business strategy for the combined company. Under the merger agreement, neither Transocean nor GlobalSantaFe may, without the prior written consent of the other, take or agree to take any of the actions described in the preceding sentence.


Court Approval of the Transactions

        Pursuant to sections 86 and 87 of the Cayman Islands Companies Law (2007 Revision) (the "Companies Law"), each of the Merger and the Reclassification requires court approval in the Cayman Islands. This requires each of the companies to file separate petitions (the "Petitions") and summonses for directions with the Grand Court of the Cayman Islands (the "Grand Court"). Prior to the mailing of this joint proxy statement, Transocean and GlobalSantaFe obtained directions from the Grand Court providing for the convening of Transocean and GlobalSantaFe shareholder meetings and other

110



procedural matters regarding these meetings and the Grand Court proceedings, including a date upon which the Grand Court will hear the Petitions. Copies of the Grand Court's directions are attached as Annexes I and J. Subject to shareholders of Transocean and GlobalSantaFe each approving the respective scheme of arrangement proposals with the votes required by the Companies Law, a subsequent Grand Court hearing will be required to hear the Petitions and seek the sanction of the Transactions (the "Sanction Hearing"). At the Sanction Hearing, the Grand Court may impose such conditions as it deems appropriate in relation to the Merger and/or the Reclassification but may not impose any material changes without the joint consent of Transocean, GlobalSantaFe and Merger Sub. If you are a Transocean or GlobalSantaFe shareholder who wishes to appear or be represented and present evidence or arguments at the Sanction Hearing, you must have voted at the relevant shareholder meeting. See "The Transocean Meeting" or "The GlobalSantaFe Meeting," as the case may be, for more information. In accordance with their terms, the Transactions will become effective as soon as (a) a copy of the Order of the Grand Court sanctioning the Transactions has been delivered to the Registrar of Companies in the Cayman Islands as required by section 86(3) of the Companies Law and (b) all conditions to the Transactions have been satisfied or waived. See "The Merger Agreement—Conditions to the Transactions" for more information on these conditions.

        The schemes of arrangement to effect the Reclassification and the Merger, which are attached as Annexes G and H to this joint proxy statement, respectively, set forth the specific terms of the Reclassification and the Merger. At their respective meetings, the shareholders of each of Transocean and GlobalSanteFe will be asked to approve the applicable scheme of arrangement. If the shareholders approve the schemes of arrangement, then Transocean and GlobalSantaFe will ask the Grand Court to sanction each scheme of arrangement. We encourage you to read both of the scheme of arrangement documents in their entirety for a complete description of their terms and conditions.

        Once a copy of the order of the Grand Court sanctioning the Transocean scheme of arrangement has been delivered to the Registrar of Companies in the Cayman Islands, the Grand Court will have exclusive jurisdiction to hear and determine any suit, action or proceeding and to settle any dispute which arises out of or connected with the terms of the Transocean scheme of arrangement or their implementation or out of any action taken or omitted to be taken under the Transocean scheme of arrangement or in connection with the administration of the Transocean scheme of arrangement. A Transocean shareholder who wishes to enforce any rights under the Transocean scheme of arrangement after such time must notify Transocean in writing of its intention at least five business days prior to commencing a new proceeding. After the effective time of the Transactions, no shareholder may commence a proceeding against Transocean in respect of or arising from the Transocean scheme of arrangement except to enforce its rights under that scheme where a party has failed to perform its obligations under that scheme.

        Once a copy of the order of the Grand Court sanctioning the GlobalSantaFe scheme of arrangement has been delivered to the Registrar of Companies in the Cayman Islands, the Grand Court will have exclusive jurisdiction to hear and determine any suit, action or proceeding and to settle any dispute which arises out of or connected with the terms of the GlobalSantaFe scheme of arrangement or their implementation or out of any action taken or omitted to be taken under the GlobalSantaFe scheme of arrangement or in connection with the administration of the GlobalSantaFe scheme of arrangement. A former GlobalSantaFe shareholder who wishes to enforce any rights under the GlobalSantaFe scheme of arrangement after such time must notify Transocean in writing of its intention at least five business days prior to commencing a new proceeding. After the effective time of the Transactions, no former GlobalSantaFe shareholder may commence a proceeding in respect of or arising from the GlobalSantaFe scheme of arrangement except to enforce its rights under that scheme where a party has failed to perform its obligations under that scheme.

        When under any provision of the Transocean scheme of arrangement or GlobalSantaFe scheme of arrangement after the effective time of the Transactions, a matter is to be determined by Transocean,

111



then Transocean will have discretion to interpret those matters under the applicable scheme of arrangement in a manner that Transocean considers fair and reasonable, and its decisions will be binding on all concerned.

        Transocean and GlobalSantaFe may jointly consent to any modification of the Transocean scheme of arrangement on behalf of the Transocean shareholders which the Grand Court may think fit to approve or impose. Transocean and GlobalSantaFe may jointly consent to any modification of the GlobalSantaFe scheme of arrangement on behalf of the GlobalSantaFe shareholders which the Grand Court may think fit to approve or impose.


Federal Securities Law Consequences; Resale Restrictions

        The issuance of Transocean ordinary shares to Transocean's shareholders and GlobalSantaFe's shareholders in connection with the Transactions will not be registered under the Securities Act of 1933 (the "Securities Act"). Section 3(a)(10) exempts securities issued in exchange for one or more outstanding securities from the general requirement of registration where the terms and conditions of the issuance and exchange of such securities have been approved by any court of competent jurisdiction, after a hearing upon the fairness of the terms and conditions of the issuance and exchange at which all persons to whom such securities will be issued have a right to appear and to whom adequate notice of the hearing has been given. In determining whether it is appropriate to convene the shareholder scheme meetings convened pursuant to its directions, the Grand Court will consider whether the terms and conditions of the Reclassification and the Merger are fair. The Grand Court has fixed the date for the hearing of the applications to approve the Transactions at            , 2007, at the court house in George Town, Grand Cayman, Cayman Islands. The Transocean ordinary shares issued to Transocean and GlobalSantaFe shareholders in connection with the Transactions will be freely transferable, except for restrictions applicable to certain "affiliates" of Transocean or GlobalSantaFe under the Securities Act, as follows:

        Persons who may be deemed to be affiliates of Transocean or GlobalSantaFe for these purposes generally include individuals or entities that control, are controlled by, or are under common control with, Transocean or GlobalSantaFe, and would not include shareholders who are not executive officers, directors or significant shareholders of Transocean or GlobalSantaFe.

112



        The merger agreement requires both Transocean and GlobalSantaFe to prepare and deliver a list that identifies all persons whom the companies believe may be deemed to be affiliates prior to the completion of the Transactions. Both companies are also required, pursuant to the merger agreement, to use their commercially reasonable best efforts to cause each person whom each company identifies on the list as a potential affiliate to deliver, at or prior to the completion of the Transactions, a written agreement that the affiliate will not sell, pledge, transfer or otherwise dispose of any of the Transocean ordinary shares issued to the affiliate pursuant to the Transactions unless the sale, pledge, transfer or other disposition meets one of the following criteria:

        This joint proxy statement does not cover any resales of the Transocean ordinary shares to be received by Transocean's shareholders and GlobalSantaFe's shareholders in the Transactions, and no person is authorized to make any use of this joint proxy statement in connection with any resale.


Rights of Dissenting Shareholders

GlobalSantaFe Shareholders

        No applicable law in connection with the Transactions, including the Companies Law, entitles GlobalSantaFe shareholders to any appraisal rights.

Transocean Shareholders

        No applicable law in connection with the Transactions, including the Companies Law, entitles Transocean shareholders to any appraisal rights.


Stock Exchange Listing

        The Transocean ordinary shares to be issued to Transocean's shareholders and GlobalSantaFe's shareholders in the Transactions will be listed on the NYSE, subject to official notice of issuance. The completion of the Transactions is conditioned upon such authorization for listing.

113



Effect of the Transactions on Transocean Share Price

        Transocean believes that the Reclassification is economically equivalent to an approximately $10 billion pro rata share repurchase or, on a per share basis, a repurchase of 0.3004 Transocean ordinary shares for $33.03. The terms of the Reclassification were based on the closing price of the Transocean ordinary shares on the day prior to execution of the merger agreement of $109.97, and the increasing effect on the share price of the reduction in the number of Transocean's ordinary shares was intended to offset the reducing effect on the share price of the cash payment in the Reclassification.

        The difference between the closing price of the Transocean ordinary shares on the day prior to closing of the Transactions and the $33.03 cash payment should reflect the market value of 0.6996 Transocean ordinary shares on such date. As a result, if such closing price is higher than $109.97, we would expect the reducing effect on the share price of the cash payment to be smaller than the increasing effect on the share price of the reduction in the number of Transocean's ordinary shares, resulting in a higher trading price of the Transocean ordinary shares immediately following closing of the Transactions, assuming no other influences affect such trading price. Similarly, if such closing price is lower than $109.97, we would expect the reducing effect on the share price of the cash payment to be greater than the increasing effect on the share price of the reduction in the number of Transocean's ordinary shares, resulting in a lower trading price of the Transocean ordinary shares immediately following closing of the Transactions, assuming no other influences affect such trading price.

114



THE MERGER AGREEMENT

        The following is a summary of the material terms of the merger agreement, a copy of which is attached as Annex A to this joint proxy statement. The provisions of the merger agreement are extensive and not easily summarized, and the summary below and elsewhere in this joint proxy statement is qualified in its entirety by reference to the merger agreement. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. We urge you to read the merger agreement in its entirety for a more complete description of the terms and conditions of the Transactions, because it together with the Transocean Scheme Document and GlobalSantaFe Scheme Document, and not this summary or this joint proxy statement, is the legal document that governs the Transactions.

        In reviewing the merger agreement, please remember that it is included to provide you with information regarding its terms and is not intended to provide any other factual information about Transocean or GlobalSantaFe. The merger agreement contains representations and warranties by each of the parties to the merger agreement. These representations and warranties have been made solely for the benefit of the other parties to the merger agreement and:


General

        At the effective time of the Merger, GlobalSantaFe will merge with Transocean Worldwide Inc., a direct wholly owned subsidiary of Transocean ("Merger Sub"), by way of a scheme of arrangement qualifying as an amalgamation under Cayman Islands law, with Merger Sub being the surviving corporation.

        Immediately prior to the Merger, each outstanding ordinary share of Transocean will be reclassified by way of a scheme of arrangement under Cayman Islands law into 0.6996 Transocean ordinary shares and $33.03 in cash pursuant to the Reclassification. At the effective time of the Merger, each outstanding ordinary share of GlobalSantaFe will be exchanged for 0.4757 Transocean ordinary shares (after giving effect to the Reclassification) and $22.46 in cash. The parties expect there will be approximately 291 million and 310 million issued and outstanding Transocean ordinary shares before and after the Transactions, respectively.

        The closing of the Merger will take place promptly after all of the conditions to the Transactions described in "—Conditions to the Transactions" are fulfilled or waived. As soon as practicable following the satisfaction of such conditions, Transocean will file the order of the Grand Court sanctioning the Reclassification with the Registrar of Companies of the Cayman Islands and the Reclassification will be effective at such time. The Merger will be effective at the time that is the later to occur of the filing of order of the Grand Court sanctioning the Merger with the Registrar of Companies of the Cayman Islands and one minute following the effectiveness of the Reclassification.

        At the effective time of the Merger, all outstanding GlobalSantaFe stock options and share appreciation rights will be assumed by Transocean and converted into awards to receive Transocean ordinary shares. GlobalSantaFe restricted stock units will be exchanged for the same consideration for which each outstanding ordinary share of GlobalSantaFe is exchanged in the Merger. At the effective

of the Reclassification, each outstanding Transocean stock option will be adjusted in connection with the Transactions. Transocean deferred units and restricted shares will be exchanged for the same consideration for which each outstanding ordinary share of Transocean is exchanged in the Reclassification. However, the holders of the awards made between July 21, 2007, and the earlier of (1) the closing of the Transactions and (2) the termination of the merger agreement will receive, with respect to each such deferred unit or restricted share, the cash consideration for which each outstanding ordinary share of Transocean is exchanged in the Reclassification.


Corporate Governance Matters

        At the effective time of the Merger, the board of directors of Transocean will be comprised of seven persons who were designated by Transocean from its current board of directors and seven persons who were designated by GlobalSantaFe from its current board of directors, as more particularly described under "The Transactions—Interests of Certain Persons in the Transactions—Governance and Management of Transocean Following the Transactions." If any director designated by Transocean or GlobalSantaFe shall die, resign, be removed, or otherwise fail to serve on the board of directors of Transocean prior to the second anniversary of the effective time of the Merger, then the remaining Transocean or GlobalSantaFe directors, as applicable, will designate a replacement, unless a majority of such group of directors determines in their sole discretion not to replace any such director. The merger agreement further provides that, at the effective time of the Merger, Robert E. Rose, the current chairman of the board of directors of GlobalSantaFe, will become chairman of the board of Transocean. Furthermore, each committee of the Transocean board of directors will be comprised of an equal number of directors designated by Transocean and GlobalSantaFe, with directors designated by GlobalSantaFe serving as chairmen of the audit and executive compensation committees and with directors designated by Transocean serving as chairmen of the corporate governance and finance and benefits committees.

        Pursuant to the merger agreement, at the effective time of the Merger, Robert L. Long will be the Chief Executive Officer of Transocean, and Jon A. Marshall will be the President and Chief Operating Officer of Transocean. The Transocean articles of association will also provide that prior to the second anniversary of the effective time of the Merger, any action to remove, replace or appoint a new chairman of the board, chief executive officer or president and chief operating officer of Transocean will require the approval of two-thirds of the entire Transocean board of directors. Please see "The Transactions—Amendment and Restatement of Transocean's Memorandum of Association and Articles of Association" for a further discussion. In addition, the parties have agreed that the following individuals will serve as officers of Transocean: Jean P. Cahuzac, Executive Vice President, Asset Management; Steven L. Newman, Executive Vice President, Operations; Eric B. Brown, Senior Vice President, General Counsel and Secretary; Gregory L. Cauthen, Senior Vice President and Chief Financial Officer; David J. Mullen, Senior Vice President, Marketing and Corporate Strategy; Cheryl D. Richard, Senior Vice President, Human Resources and Information Technology; Robert L. Herrin, Vice President, Audit and Advisory Services; and Gregory S. Panagos, Vice President, Investor Relations.

agreement, in each case except as permitted by the merger agreement or as required by applicable law, unless consented to in writing by the other party:

        Each of Transocean and GlobalSantaFe has agreed to refrain from taking, and to cause its subsidiaries to refrain from taking, the following actions until the effective time of the Merger or the termination of the merger agreement, in each case except as permitted by the merger agreement or agreed to in writing by the other party:

117


118


        The merger agreement provides that, subject to limited exceptions described below, each of Transocean and GlobalSantaFe will not, and will cause its officers, directors, employees, agents and other representatives not to, directly or indirectly, solicit, initiate or knowingly encourage (including by way of furnishing nonpublic information), or take any action designed to approve, endorse, recommend or facilitate, directly or indirectly, any inquiry, proposal or offer (including any proposal or offer to its shareholders) with respect to a tender or exchange offer, scheme of arrangement, merger, consolidation, business combination, purchase or similar transaction involving:

Any such transaction is referred to in this joint proxy statement as an "acquisition proposal."

        In addition, each of Transocean and GlobalSantaFe has agreed not to, and not to permit any of its representatives to, cooperate with or assist, participate or engage in any substantive discussions or negotiations concerning an acquisition proposal with respect to it, or amend, terminate, waive or fail to enforce, or grant any consent under, any confidentiality, standstill or similar agreement.

        Nothing in the merger agreement, however, prevents Transocean or GlobalSantaFe from:

119


        Furthermore, notwithstanding anything in the merger agreement to the contrary, the board of directors of Transocean or GlobalSantaFe may make an "adverse recommendation change" by:

        A "superior proposal" means, with respect to Transocean or GlobalSantaFe, an unsolicited bona fide written acquisition proposal with respect to all of the outstanding ordinary shares or all or substantially all the assets of such party that, in the good faith judgment of such party's board of directors, taking into account the likelihood of financing, shareholder approval and other requirements for consummation, after consultation with a financial advisor of recognized national reputation, is superior to the Transactions, in the case of Transocean, and to the Merger, in the case of GlobalSantaFe. For the purposes of making a superior proposal determination, it is understood by the parties that such determination necessarily will (1) be based on limited information compared to a termination determination made in connection with a superior proposal as described under "—Termination of the Merger Agreement" below, (2) require assumptions that shall be made in the good faith judgment of such party's board of directors and (3) not be as complete or informed as, and will be distinct from, a superior proposal determination made for the purposes described under "—Termination of the Merger Agreement" below.

        Prior to participating in any substantive discussions or negotiations and as promptly as practicable (and in any event within 24 hours) after receipt of an acquisition proposal, any inquiry with respect to an acquisition proposal, or any request for information in connection with such a proposal, the party receiving such proposal or request has agreed to:

120


        Transocean has agreed to submit the Reclassification (if so ordered by the Grand Court), the issuance of Transocean ordinary shares in the Merger and the amendment and restatement of its articles of association and memorandum of association to its shareholders regardless of whether the Transocean board of directors makes an adverse recommendation change. The board of directors of Transocean will recommend approval of the Reclassification and issuance of Transocean ordinary shares in the Merger, and use its reasonable best efforts to solicit proxies from its shareholders in favor of such matters, unless, prior to the approval of such matters by its shareholders, and upon one business day's notice to GlobalSantaFe, in the good faith opinion of the board of directors of Transocean, after consultation with its outside legal counsel, board determines the failure to withdraw its recommendation would be inconsistent with its fiduciary obligations.

        GlobalSantaFe has agreed to submit the Merger (if so ordered by the Grand Court) to its shareholders regardless of whether the GlobalSantaFe board of directors makes an adverse recommendation change. The board of directors of GlobalSantaFe will recommend approval of the Merger, and use its reasonable best efforts to solicit proxies from its shareholders in favor of the Merger, unless, prior to the approval of such matters by its shareholders, and upon one business day's notice to Transocean, in the good faith opinion of the board of directors of GlobalSantaFe, after consultation with its outside legal counsel, the board determines the failure to withdraw its recommendation would be inconsistent with its fiduciary obligations.

        Each of Transocean and GlobalSantaFe has agreed to:

121


122


        Nothing in the merger agreement requires Transocean or GlobalSantaFe to take any competition action (as defined below) to obtain any consents, approvals, permits or authorizations or to remove any impediments to the Merger relating to the HSR Act, non-U.S. antitrust laws or other antitrust, competition or premerger notification trade regulation law, regulation or order or to the avoid the entry of, or to the effect the dissolution of, any injunction, temporary restraining order or other order in any suit or proceedings relating to antitrust laws. A "competition action" means, with respect to Transocean or GlobalSantaFe, to dispose of any of its assets or limit its freedom of action with respect to any of its businesses, or to consent to any such disposition or limitation of its freedom, whether prior to or after the effective time of the Merger, or to commit or agree to any of the foregoing, other than dispositions, limitations or consents, commitments or agreements conditioned upon the consummation of the Mergers and the transactions contemplated by the merger agreement and which, in the reasonable good faith judgment of both of the parties, do not and are not reasonably likely (individually or in the aggregate) to:

        Furthermore, neither party shall take or agree to take any competition action without the prior written agreement of the other party.

        From and after the effective time of the Merger, Transocean and Merger Sub have agreed to indemnify, defend and hold harmless to the fullest extent permitted under applicable law each person who is, or has been at any time prior to the effective time of the Merger, an executive officer or director of Transocean or GlobalSantaFe (or any subsidiary or division thereof) and each person who served at the request of Transocean or GlobalSantaFe as a director, officer, trustee or fiduciary of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise against all losses, claims, damages, liabilities, costs or expenses (including attorneys' fees), judgments, fines, penalties and amounts paid in settlement in connection with any claim, action, suit, proceeding or investigation arising out of or pertaining to acts or omissions, or alleged acts or omissions, by them in their capacities as such, whether commenced, asserted or claimed before or after the effective time of the Merger.

        Each of Transocean and GlobalSantaFe has agreed that the rights to indemnification, including provisions relating to advances of expenses incurred in defense of any action or suit, in its memorandum of association and articles of association with respect to matters occurring through the effective time of the Merger, shall survive the Merger.

123



        For a period of six years after the effective time of the Merger, Transocean and Merger Sub have agreed to maintain directors' and officers' liability insurance covering the indemnified parties who are, or at any time prior to the effective time of the Merger were, covered by Transocean and GlobalSantaFe's existing directors' and officers' liability insurance policies on terms substantially no less advantageous to the indemnified parties than such existing insurance; provided, that Transocean and Merger Sub are not required to pay annual premiums in excess of 250% of the last annual premium paid by Transocean.

        Transocean has agreed to continue the employment of all of the employees who are employed by either party as of the day immediately prior to the effective time of the Merger initially at the same salaries and wages of such employees immediately prior to the effective time of the Merger. During the period from the effective time of the Merger through December 31, 2008, Transocean will:

        Transocean has also agreed to honor, and to enter into novation agreements with respect to, specified severance agreements of GlobalSantaFe.

        Transocean will credit each employee for the period of employment and service recognized by the applicable employer immediately prior to the effective time of the Merger for purposes of determining such employee's eligibility to join (subject to satisfaction of all non-service related eligibility criteria) and vesting under (but not benefit accrual for any purpose other than vacation pay, severance and termination pay, sick leave, post-retirement health coverage and satisfaction of early retirement criteria) all employee benefit plans, programs, policies or similar employment related arrangements of Transocean in which such employee is eligible to participate.

        Transocean will waive, and use its best efforts to cause the relevant insurance carriers and other third parties to waive, pre-existing conditions, subject to certain exceptions. Transocean will also offer employees coverage under a group health plan that credits expenses already incurred by such employee in the year in which the effective time of the Merger occurs.

        Transocean will also establish a severance plan with general terms as previously agreed by the parties. Such plan will be effective for at least two years from the effective time of the Merger and will be for the benefit of eligible persons employed as of the effective time of the Merger on a U.S. dollar payroll. The parties have further agreed to cooperate in good faith to take appropriate and substantially consistent actions to retain key employees and provide for a smooth transition, including such action as they deem appropriate to provide for retention payments following the closing date.

        Transocean will pay to each employee who was employed by it immediately prior to the effective time of the Merger an amount, to the extent then unpaid, equal to the annual incentive bonus to which the affected employee would be entitled under the terms of Transocean's 2007 Performance Award and Cash Bonus Plan and applicable award letters. No later than March 14, 2008, Transocean will pay to each employee who was employed by GlobalSantaFe immediately prior to the effective time of the

124



Merger (or if the effective time shall have not yet occurred, GlobalSantaFe shall pay to each person who is an employee of GlobalSantaFe on March 14, 2008):


        If the employment of an employee who would otherwise be entitled to a payment under the immediately preceding provisions is involuntarily terminated, or such an employee voluntarily terminates employment after attaining age 55 and five years of service, prior to March 14, 2008, the payment or payments shall nevertheless be made to such employee on March 14, 2008.

        In the event the effective time of the Merger occurs in 2008, immediately prior to the effective time:

        Except with respect to offers of employment to prospective new employees in the ordinary course of business, Transocean and GlobalSantaFe agree not to make any representations or promises concerning continued employment after the effective time of the Merger or the terms and conditions of employment.

        The merger agreement provides that, for the avoidance of doubt, Transocean deems that the Transactions constitute a change of control of Transocean with respect to (1) the Transocean Executive Change of Control Severance Benefit, (2) the Long-Term Incentive Plan of Transocean, (3) the Deferred Compensation Plan of Transocean, (4) the Performance Award and Cash Bonus Plan of Transocean and (5) any awards under the Transocean stock plans, except for specified awards granted after July 20, 2007.

        As soon as practicable, each of Transocean and GlobalSantaFe has agreed to:

125


        As soon as practicable following the satisfaction or waiver of the conditions to the Transactions, Transocean and GlobalSantaFe shall each cause its respective order of the Grand Court sanctioning the Reclassification (in the case of Transocean) and the Merger (in the case of GlobalSantaFe) to be filed with the Registrar of Companies of the Cayman Islands. The Reclassification shall be effective at the time of such filing by Transocean and the Merger shall be effective upon the latter to occur of such filing by GlobalSantaFe or one minute following such filing by Transocean. The effect of the Merger will be to transfer the assets, liabilities and undertaking of GlobalSantaFe to Merger Sub. GlobalSantaFe will be dissolved without a winding up and it will thereby cease to exist as a company.

        Each of Transocean and GlobalSantaFe has agreed to use its reasonable best efforts to:

        Each party agrees to give the other party prompt notice upon becoming aware of any termination of the financing commitments or any event that makes procurement of any portion of the financing unlikely in the manner or from the sources contemplated in the financing commitments, in which case, Transocean and, at the direction and guidance of Transocean, GlobalSantaFe, will use their reasonable best efforts to arrange as promptly as practicable any such portion from alternate sources on terms and conditions substantially no less favorable to Transocean. Transocean will take and use reasonable best efforts to cause its subsidiaries to take, and at the request of Transocean, GlobalSantaFe will take and use its reasonable best efforts to cause its subsidiaries to take, all actions reasonably necessary in connection with the financing.

        In connection with the financing, each of Transocean and GlobalSantaFe has agreed to use its reasonable best efforts to:

126


        Transocean and GlobalSantaFe have further agreed that Transocean shall pay two-thirds and GlobalSantaFe shall pay one-third of all reasonable out-of-pocket third party costs incurred by either party in connection with the financing.

        In the event that the Transactions are not consummated due to a failure to obtain the financing, no party will have liability to the other arising out of such failure but neither party is relieved of its obligations to use its reasonable best efforts to obtain the financing as required by the merger agreement.

        Prior to and at the effective time of the Merger, each of Transocean and GlobalSantaFe has agreed to use its reasonable best efforts to:

        The parties further agree to take all actions required for Merger Sub, at the effective time of the Merger, to be disregarded as an entity separate from its owner, Transocean, for U.S. federal tax purposes.


Representations and Warranties

        Transocean and Merger Sub, on the one hand, and GlobalSantaFe, on the other hand, have made various representations and warranties in the merger agreement, which are substantially reciprocal, to each other. Those representations and warranties generally pertain to:

127



Conditions to the Transactions

        Each party's obligation to effect the Merger and the Reclassification is subject to the satisfaction or waiver of the following conditions:

128


        In addition, the obligation of GlobalSantaFe to effect the Merger is subject to the fulfillment or waiver of the following conditions:

129



        In addition, the obligation of Transocean and Merger Sub to effect the Transactions is subject to the fulfillment or waiver of the following conditions:

130



Termination of the Merger Agreement

        GlobalSantaFe and Transocean may terminate the merger agreement at any time by written mutual consent.

        The board of directors of either GlobalSantaFe or Transocean may terminate the merger agreement at any time prior to the effective time of the Merger if:

        The board of directors of GlobalSantaFe may terminate the merger agreement at any time, after consultation with its outside legal advisors, if:

131


        The board of directors of Transocean may terminate the merger agreement at any time, after consultation with its outside legal advisors, if:

132



Termination Fees and Expenses

        Termination of the merger agreement may require GlobalSantaFe or Transocean to pay a cash termination fee of $300 million under certain circumstances.

        GlobalSantaFe will be required to pay the termination fee at the time of termination of the merger agreement where the merger agreement is terminated:

        GlobalSantaFe will be required to pay the termination fee at the time of entry into a definitive agreement or consummation of an acquisition proposal for GlobalSantaFe where the merger agreement is terminated by either party due to failure to obtain the requisite approval of GlobalSantaFe's shareholders, where a termination fee is not otherwise payable upon such termination as described above:


        Transocean will be required to pay the termination fee at the time of termination of the merger agreement where the merger agreement is terminated:

133


        Transocean will be required to pay the termination fee at the time of entry into a definitive agreement or consummation of an acquisition proposal for Transocean where the merger agreement is terminated by either party due to failure to obtain the requisite approval of Transocean's shareholders, where a termination fee is not otherwise payable upon such termination as described above:

        If the merger agreement is terminated by either party due to the failure to obtain GlobalSantaFe shareholder approval or by Transocean due to an adverse recommendation change by GlobalSantaFe, and no termination fee is otherwise required to be paid by GlobalSantaFe under the merger agreement, then GlobalSantaFe will reimburse Transocean for its third party costs and expenses in connection with the Transactions, up to a maximum of $30 million.

        If the merger agreement is terminated by either party due to the failure to obtain Transocean shareholder approval or by GlobalSantaFe due to an adverse recommendation change by Transocean, and no termination fee is otherwise required to be paid by Transocean under the merger agreement, then Transocean will reimburse GlobalSantaFe for its third party costs and expenses in connection with the Transactions, up to a maximum of $30 million.

        In the event that either party has reimbursed certain expenses of the other party and, subsequently, is required to pay the $300 million termination fee, then the amount of costs and expenses so reimbursed will be offset against the fee payable.


Amendments

        The parties may amend the merger agreement by action taken by their boards of directors, at any time before or after approval by their shareholders of matters presented in connection with the Transactions. After any such shareholder approval, no amendment shall be made that by law requires the further approval of shareholders unless such further approval is obtained.

BUSINESS OF TRANSOCEAN

        Transocean is a leading international provider of offshore contract drilling services for oil and gas wells. As of July 31, 2007, Transocean owned, had partial ownership interests in or operated 82 mobile offshore drilling units. As of this date, Transocean's fleet included 33 High-Specification semisubmersibles and drillships ("High-Specification Floaters"), 20 Other Floaters, 25 Jackups and four Other Rigs. Transocean also has four High-Specification Floaters under construction.

        Transocean's mobile offshore drilling fleet is considered one of the most modern and versatile fleets in the world. Transocean's primary business is to contract these drilling rigs, related equipment and work crews primarily on a dayrate basis to drill oil and gas wells. Transocean specializes in technically demanding segments of the offshore drilling business with a particular focus on deepwater and harsh environment drilling services. Transocean also provides additional services, including integrated services.

        Transocean is a Cayman Islands exempted company with principal executive offices in the United States located at 4 Greenway Plaza, Houston, Texas 77046. Its telephone number at that address is (713) 232-7500.

135



BUSINESS OF GLOBALSANTAFE

        GlobalSantaFe is an offshore oil and gas drilling contractor, owning or operating a modern and diversified fleet of 59 marine drilling rigs, plus one rig under construction. GlobalSantaFe provides offshore oil and gas contract drilling services to the oil and gas industry worldwide on a daily rate (or "dayrate") basis. GlobalSantaFe also provides oil and gas drilling management services on either a dayrate or completed-project, fixed-price (or "turnkey") basis, as well as drilling engineering and drilling project management services, and it participates in oil and gas exploration and production activities. Under a typical turnkey arrangement, GlobalSantaFe assumes responsibility for the design and execution of a well and delivers a logged or cased hole to an agreed depth for a guaranteed price, with payment contingent upon successful completion of the well program.

        As of July 31, 2007, GlobalSantaFe's fleet included:


        GlobalSantaFe has also entered into a contract with Keppel FELS, a shipyard located in Singapore, for construction of a new ultra-deepwater semisubmersible. Delivery is currently expected during the first quarter of 2009.

        GlobalSantaFe's fleet is deployed in major offshore oil and gas operating areas worldwide. The principal areas in which its fleet is currently deployed are the U.S. Gulf of Mexico, the North Sea, West Africa, the Mediterranean Sea, Southeast Asia, South America, the Middle East and eastern Canada.

See "Where You Can Find More Information" on page 170.

136



FINANCING OF THE TRANSACTIONS

        In connection with the Transactions, on July 21, 2007, Transocean and GlobalSantaFe entered into a commitment letter pursuant to which Goldman Sachs Credit Partners L.P. ("GSCP"), and Lehman Brothers Commercial Bank and Lehman Brothers Holdings Inc. and their respective affiliates (collectively, the "Lehman Lenders") have committed to provide financing for the Transactions. The commitment letter provides for a $15.0 billion senior unsecured bridge loan facility due one year after closing (the "Bridge Loan Facility"), $10.0 billion of which is to be provided by GSCP and $5.0 billion of which is to be provided by the Lehman Lenders (except to the extent such commitments to provide financing are assigned to other lenders under the Bridge Loan Facility).

        Transocean and GlobalSantaFe expect that if the definitive agreement that would govern the Bridge Loan Facility is entered into, Transocean may make borrowings at either (1) a base rate or (2) the reserve adjusted Eurodollar rate plus the applicable margin, which would be based upon Transocean's non-credit enhanced senior unsecured long-term debt rating. Transocean and GlobalSantaFe expect that the Bridge Loan Facility may be prepaid in whole or in part without premium or penalty. In addition, the Bridge Loan Facility is expected to require mandatory prepayments in an amount equal to 100 percent of the net cash proceeds resulting from any of the following (in each case with exceptions to be agreed): (A) the sale or other disposition of any property or assets of Transocean or it subsidiaries above a predetermined threshold; (B) certain issuances of equity securities of Transocean or its subsidiaries; and (C) the incurrence of indebtedness for borrowed money by Transocean or its subsidiaries.

        The Bridge Loan Facility is expected to contain certain covenants, including a maximum leverage ratio and covenants restricting the combined company's ability to pay dividends. Borrowings under the Bridge Loan Facility are expected to be subject to acceleration upon the occurrence of events of default.

        Each of GSCP's and the Lehman Lenders' obligation to make loans under the Bridge Loan Facility is subject to the satisfaction of certain conditions, including the execution of satisfactory documentation and the absence of a material adverse effect (as defined in the merger agreement). There can be no assurance that these conditions will be met.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Sources of Information

        The following unaudited pro forma condensed combined financial statements and related notes present the combined financial statements of Transocean and GlobalSantaFe as if the Transactions actually been completed on June 30, 2007 with respect to the balance sheet data or on January 1 of the year presented with respect to the operating results data. The unaudited condensed pro forma combined financial information has been derived from and should be read together with the historical consolidated financial statements and related notes of Transocean and GlobalSantaFe, which are incorporated into this joint proxy statement by reference. See "Where You Can Find More Information" beginning on page 170.

How We Prepared the Unaudited Pro Forma Financial Information

        The balance sheet data assume the Transactions had been completed on June 30, 2007, and the operating results data assume the Transactions were completed on January 1 of the year presented. If the Transactions had been completed on the dates assumed in the pro forma financial statements, the combined company might have performed differently. The unaudited pro forma condensed combined financial statements are presented for illustrative purposes only and do not reflect the impact of possible cost savings and operational efficiencies nor do they reflect implementation and integration costs and potential costs of harmonizing employee salary and benefit structures. You should not rely on the pro forma financial information as an indication of the financial position or results of operations that the combined company would have achieved had the Transactions taken place earlier or the future results that the combined company will achieve after the Transactions.

        Transocean will account for the Reclassification as a reverse stock split and a dividend, which will require restatement of historical weighted average shares outstanding and historical earnings per share for prior periods. Transocean prepared the pro forma combined financial information for the Merger using the purchase method of accounting, with Transocean treated as the acquirer. As a result, the assets and liabilities of Transocean remain at historical amounts, without restatement to fair values. The assets and liabilities of GlobalSantaFe are recorded at their preliminary estimated fair values at the assumed date of completion of the Transactions, with the excess of the purchase price over the sum of these fair values recorded as goodwill. The preliminary estimates of fair values are subject to change based on the fair values and the final valuations that will be determined as of the closing date of the Transactions.

        The Transocean unaudited condensed pro forma combined financial statements reflect a total purchase price of $17.5 billion, which was calculated using the estimated number of Transocean ordinary shares to be issued in the Merger and a $113.11 per share average trading price of Transocean ordinary shares for a period of time immediately before and after the Transactions were announced, plus estimated cash consideration to be paid to GlobalSantaFe shareholders based on the number of GlobalSantaFe ordinary shares estimated to be outstanding at the time of the Merger and cash consideration of $22.46 per share plus estimated direct Merger costs and expenses and the estimated fair value of GlobalSantaFe stock options and share appreciation rights to be assumed by Transocean. The estimated $9.6 billion cash payment, which is characterized as a dividend for accounting purposes, to Transocean shareholders is calculated based on the number of Transocean ordinary shares estimated to be outstanding at the time of the Reclassification.

Transaction-Related Expenses

        Transocean estimates that it will incur fees and expenses totaling approximately $33 million in connection with the Transactions, and it has included these costs in calculating the purchase price. Additionally, GlobalSantaFe estimates that it will incur fees and expenses totaling approximately

143



$38 million related to the Transactions. After the Transactions, Transocean expects to incur additional charges and expenses relating to restructuring and integrating the operations of GlobalSantaFe and Transocean, the amount of which has not yet been determined.

        Transocean expects to pay approximately $5 million in connection with the retention of key employees following the effective time of the Merger as described in "The Merger Agreement Covenants—Employee Matters." Additionally, Transocean will establish a severance plan as described in "the Transactions—Employee Benefit Matters." In connection with the severance plan, Transocean expects to recognize expense of approximately $25 million.

        Transocean's Performance Award and Cash Bonus Plan contains a change of control clause that provides for payment of the maximum amount of the award that could have been earned under that plan. As a result, Transocean expects to recognize approximately $50 million in expense in the event the Transactions are completed assuming the effective time of the Transactions occurs on or before December 31, 2007.

        In addition, Transocean expects to recognize approximately $30 million in expense related to accelerating the recognition the share-based compensation for existing awards under the Long-Term Incentive Plan that are affected by the Reclassification.

        The pro forma statement of operations has not been adjusted for these additional charges and expenses or for other potential cost savings and operational efficiencies that may be realized as a result of the Transactions.

DESCRIPTION OF SHARE CAPITAL OF TRANSOCEAN

        The following description of Transocean's share capital is a summary. This summary is not complete and is subject to the complete text of the memorandum of association (the "memorandum") and articles of association (the "articles") and, when applicable, the amended and restated memorandum and articles attached as Annexes E and F, respectively, to this joint proxy statement. Transocean's memorandum and articles are exhibits to Transocean's Annual Report on Form 10-K for the year ended December 31, 2006, and are incorporated in this joint proxy statement by reference. Transocean encourages you to read those documents carefully.

Description of Authorized Shares of Transocean

        Transocean is a Cayman Islands exempted company. Its authorized share capital is $13,000,000, divided into:

        As of August 29, 2007, 290,779,794 ordinary shares and no other class or series of shares had been issued.

Ordinary Shares

Voting

        The holders of Transocean's ordinary shares are entitled to one vote per share other than on the election of directors.

        With respect to the election of directors, each holder of Transocean's ordinary shares entitled to vote at the election has the right to vote, in person or by proxy, the number of shares held by him for as many persons as there are directors to be elected and for whose election that holder has a right to vote. The directors are divided into three classes, with only one class being up for election each year. Directors are elected by a plurality of the votes cast in the election. Cumulative voting for the election of directors is prohibited by Transocean's articles.

        There are no limitations imposed by Cayman Islands law or the articles on the right of Transocean's nonresident shareholders to hold or vote their ordinary shares.

        The rights attached to any separate class or series of shares, unless otherwise provided by the terms of the shares of that class or series, may be varied only with the consent in writing of the holders of all of the issued shares of that class or series or by a special resolution passed at a separate general meeting of holders of the shares of that class or series. The necessary quorum for that meeting is the presence in person or by proxy of holders of at least a majority of the shares of that class or series. Each holder of shares of the class or series present, in person or by proxy, will have one vote for each share of the class or series of which he is the holder. Outstanding shares will not be deemed to be varied by the creation or issuance of additional shares that rank in any respect prior to or equivalent with those shares.

        Under Cayman Islands law, some matters, like altering the memorandum or the articles, changing the name of a company, voluntarily winding up a company or resolving to be registered by way of continuation in a jurisdiction outside the Cayman Islands, require approval of shareholders by a special resolution. A special resolution is a resolution (1) passed by the holders of two-thirds of the shares voted at a general meeting (or such great number as may be specified in the articles of association of

154



the company) or (2) approved in writing by all shareholders entitled to vote at a general meeting of the company.

Quorum for General Meetings

        The presence of shareholders, in person or by proxy, holding at least a majority of the issued shares generally entitled to vote at a meeting, is a quorum for the transaction of most business. However, different quorums are required in some cases to approve a change in Transocean's articles.

        Shareholders present, in person or by proxy, holding at least 95% of the issued shares entitled to vote at a meeting constitute the required quorum at a general meeting to consider or adopt a special resolution to amend, vary, suspend the operation of or cause any of the following provisions of the articles to cease to apply:

        If the proposed resolution to amend and restate the articles is adopted, this required quorum will also be necessary to amend, vary, suspend the operation of or cause the provisions of Article 40, which sets forth certain corporate governance provisions for a two year period following the completion of the Transactions, to cease to apply. The quorum requirement for a special resolution to amend, vary, suspend the operation of or cause the provisions of Article 40 to cease to apply may be waived by the vote of two-thirds of the board of directors.

        In addition, the presence of shareholders, in person or by proxy, holding at least a majority of the issued shares entitled to vote at the meeting, is a quorum if:

        In addition, the presence of shareholders, in person or by proxy, holding at least a majority of the issued shares entitled to vote at a meeting, is also the required quorum to consider or adopt a special resolution to delete Section 27 of the articles if:

        The shareholders present at a duly constituted general meeting may continue to transact business until adjournment, despite the withdrawal of shareholders that leaves less than a quorum.

155



Dividend Rights

        Subject to the Companies Law (as amended), any rights and restrictions of any other class or series of shares, the board of directors may, from time to time, declare dividends on the shares issued and authorize payment of the dividends out of Transocean's lawfully available funds. The board of directors may declare that any dividend be paid wholly or partly by the distribution of shares of Transocean and/or specific assets.

Rights Upon Liquidation

        Upon the liquidation of Transocean, after creditors have been paid the full amounts owing to them and the holders of any issued shares ranking senior to the ordinary shares as to distribution on liquidation or winding-up are entitled to receive have been paid or set aside for payment, then the holders of Transocean's ordinary shares are entitled to receive, pro rata, any remaining assets available for distribution to the holders of ordinary shares. The liquidator may deduct from the amount payable in respect of those ordinary shares any liabilities the holder has to or with Transocean. The assets received by the holders of Transocean ordinary shares in liquidation may consist in whole or in part of property. That property is not required to be of the same kind for all shareholders.

No Sinking Fund

        The Transocean ordinary shares have no sinking fund provisions.

No Liability for Further Calls or Assessments

        The Transocean ordinary shares to be issued in the Transactions will be duly and validly issued, fully paid and nonassessable.

No Preemptive Rights

        Holders of Transocean ordinary shares have no preemptive or preferential right to purchase any securities of Transocean.

Redemption and Conversion

        The Transocean ordinary shares are not convertible into shares of any other class or series or subject to redemption either by Transocean or the holder of the shares.

Repurchase

        Under Transocean's articles, Transocean may purchase any issued ordinary shares in the circumstances and on the terms agreed by Transocean and the holder of the shares, whether or not Transocean has made a similar offer to any of the other holders of ordinary shares.

Restrictions on Transfer

        Subject to the rules of any stock exchange on which the ordinary shares may be listed, the board of directors may, in its absolute discretion and without assigning any reason, decline to register any transfer of shares.

Other Classes or Series of Shares

        Transocean's board of directors is authorized, without obtaining any vote or consent of the holders of any class or series of shares unless expressly provided by the terms of issue of that class or series, to provide from time to time for the issuance of other classes or series of shares and to establish the

156



characteristics of each class or series, including the number of shares, designations, relative voting rights, dividend rights, liquidation and other rights, redemption, repurchase or exchange rights and any other preferences and relative, participating, optional or other rights and limitations not inconsistent with applicable law.

Compulsory Acquisition of Shares Held by Minority Holders

        An acquiring party is generally able to acquire compulsorily the ordinary shares of minority holders in one of two ways:


Stock Exchange Listing

        Transocean's ordinary shares are listed on the New York Stock Exchange and trade under the symbol "RIG."

Transfer Agent

        The transfer agent and registrar for Transocean's ordinary shares is The Bank of New York.

Preference Shares

        Transocean's board of directors is authorized, without obtaining any vote or consent of the holders of any class or series of shares unless expressly provided by the terms of issue of that class or series, to provide from time to time for the issuance of up to 50,000,000 preference shares in one or more classes or series of shares. The board of directors can also establish the characteristics of each class or series, including the number of shares, designations, relative voting rights, dividend rights, liquidation and other rights, redemption, repurchase or exchange rights and any other preferences and relative, participating, optional or other rights and limitations not inconsistent with applicable law.

Anti-Takeover Provisions

        Transocean's articles have provisions that could have an anti-takeover effect. These provisions are intended to enhance the likelihood of continuity and stability in the composition of the board of directors and in the policies formulated by the board of directors, and may have the effect of

157



discouraging actual or threatened changes of control by limiting certain actions that may be taken by a potential acquiror prior to its having obtained sufficient control to adopt a special resolution amending Transocean's articles.

        The articles provide that Transocean's board of directors will be divided into three classes serving staggered three-year terms. Directors can be removed from office only for cause, as defined in the articles, by the affirmative vote of the holders of a majority of the issued shares generally entitled to vote. The board of directors does not have the power to remove directors. Vacancies on the board of directors may be filled only by the remaining directors and not by the shareholders. Each of these provisions can delay a shareholder from obtaining majority representation on the board of directors.

        If the proposed resolution to amend and restate the articles is adopted, the articles will provide that the board of directors will consist of at least two and not more than 14 persons. The exact number of directors is to be set from time to time by a majority of the whole board of directors. Accordingly, the board of directors, and not the shareholders, has the authority to determine the number of directors and could delay any shareholder from obtaining majority representation on the board of directors by enlarging the board of directors and filling the new vacancies with its own nominees until a general meeting at which directors are to be appointed.

        The articles establish an advance notice procedure that must be followed by shareholders if they wish to nominate candidates for election as directors or propose any business at an annual general meeting of shareholders. The articles provide generally that, if a shareholder desires to nominate candidates for election as directors or propose any business at an annual general meeting, that shareholder must give Transocean notice not less than 90 days prior to the anniversary of the originally scheduled date of the immediately preceding annual general meeting. However, if the date of the forthcoming annual general meeting is more than 30 days before or after the anniversary date, the deadline is the close of business on the tenth day after Transocean publicly discloses the meeting date. In each case, the notice must contain specified information concerning the shareholder submitting the proposal.

        Subject to the terms of any other class of shares in issue, any action required or permitted to be taken by the holders of Transocean's ordinary shares must be taken at a duly called annual or special general meeting of shareholders unless taken by written consent of all holders of ordinary shares. Special general meetings may be called only by a majority of the entire board of directors.

        The board of directors is authorized, without obtaining any vote or consent of the holders of any class or series of shares unless expressly provided by the terms of issue of a class or series, to issue from time to time any other classes or series of shares with the designations and relative powers, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or terms or conditions of redemption as it considers fit. The board of directors could authorize the issuance of preference shares with terms and conditions that could discourage a takeover or other transaction that holders of some or a majority of the ordinary shares might believe to be in their best interests or in which holders might receive a premium for their shares over the then market price of the shares. No preference shares have been established as of the date of this joint proxy statement.

        The special quorum provisions contained in the articles require the holders of 95% of all the voting shares to be present, in person or by proxy, at a general meeting to consider or adopt a special resolution to amend, vary, suspend the operation of or cease the application of the following provisions of the articles, unless a majority of the board of directors has recommended that the shareholders vote in favor of the special resolution:

158


        If the proposed resolution is adopted, this required quorum will also be necessary to amend, vary, suspend the operation of or cause the provisions of Article 40, which sets forth certain corporate governance provisions for a two year period following the consummation of the Transactions. The quorum requirement for a special resolution to amend, vary, suspend the operation of or cause the provisions of Article 40 may be waived by the vote of two-thirds of the board of directors.

        For a description of exceptions to the quorum requirements to amend Section 27, see the discussion under the heading "—Ordinary Shares—Quorum for General Meetings."

        Transocean's articles generally prohibit "business combinations" between the company and an "interested shareholder." Specifically, "business combinations" between an interested shareholder and Transocean are prohibited for a period of three years after the time the interested shareholder acquired its shares, unless:

        "Business combinations" is defined broadly to include mergers, consolidations of majority-owned subsidiaries, sales or other dispositions of assets having an aggregate value equal to or in excess of 10% of Transocean's consolidated assets, and most transactions that would increase the interested shareholder's proportionate share ownership in Transocean.

        "Interested shareholder" is defined as a person who, together with any affiliates and/or associates of that person, beneficially owns, directly or indirectly, 15% or more of Transocean's issued voting shares, or who is an affiliate or associate of the company and was the owner of 15% or more of Transocean's issued voting shares within the three-year period immediately prior to the date a determination is sought.

159



COMPARISON OF RIGHTS OF SHAREHOLDERS

        As a result of the Merger, holders of ordinary shares of GlobalSantaFe will become shareholders of Transocean and their rights as shareholders will be governed by Transocean's proposed amended and restated memorandum and articles of association as well as by the Companies Law of the Cayman Islands.

        This section describes the material differences between the rights of GlobalSantaFe's shareholders under its memorandum and articles of association and the rights of Transocean's shareholders under its memorandum and articles of association as they will be amended and restated at the effective time of the Merger as described under "The Transactions—Amendment and Restatement of Transocean's Memorandum of Association and Articles of Association." However, this section does not purport to be a complete statement of the rights of GlobalSantaFe shareholders under the GlobalSantaFe memorandum and articles of association or of Transocean shareholders under the Transocean proposed amended and restated memorandum and articles of association. This summary contains a list of the material differences but is not meant to be relied upon as an exhaustive list or a detailed description of the provisions discussed and is qualified in its entirety by reference to the proposed amended and restated memorandum and articles of association of Transocean and the memorandum and articles of association of GlobalSantaFe, to which the GlobalSantaFe shareholders are referred. Copies of the GlobalSantaFe memorandum and articles of association are available, without charge, by following the instructions listed under "Where You Can Find More Information" and the Transocean proposed amended and restated memorandum and articles of association are included in this joint proxy statement as Annex E and Annex F, respectively.

Capitalization

        GlobalSantaFe.    The authorized share capital of GlobalSantaFe is comprised of 600,000,000 shares, par value $0.01 per share, which may be issued as ordinary shares or such other class or series of shares having such rights and powers as determined by the GlobalSantaFe board of directors in accordance with its articles of association.

        Transocean.    The authorized share capital of Transocean is comprised of 800,000,000 ordinary shares, par value $0.01 per share, and 50,000,000 shares, par value $0.10 per share, which may be designated and created as shares of any other class or series with such rights and powers as determined by the Transocean board of directors in accordance with its articles of association.

Number of Directors

        GlobalSantaFe.    The GlobalSantaFe articles of association provide that its board of directors will be consist of not less than six nor more than 15 persons. The GlobalSantaFe board of directors has the exclusive authority to determine the number of directors within the authorized range. The GlobalSantaFe board of directors currently has ten directors.

        Transocean.    The Transocean proposed amended and restated articles of association provide that the minimum number of directors is two and the maximum number of directors is 14 (assuming Transocean shareholders approve the amended and restated articles of association), plus the number of directors that any classes of shares (other than ordinary shares) are entitled to elect, voting separately as a class. At the effective time of the Merger, the Transocean board of directors will have 14 directors, seven of which will have been Transocean directors and seven of which will have been GlobalSantaFe directors. Transocean will use its reasonable best efforts to maintain this allocation until the second anniversary of the effective time of the Merger, as more particularly described in "The Transactions—Amendment and Restatement of Transocean's Memorandum of Association and Articles of Association." below. After such time, the Transocean board of directors will have the exclusive

160



authority to determine the number of directors within the authorized range by resolution adopted by a majority of the entire board of directors.

Qualification of Directors

        GlobalSantaFe.    GlobalSantaFe's articles of association provide that no person may serve as a director of GlobalSantaFe if such person has attained the age of 70 at the time of election to the board.

        Transocean.    Transocean does not have a similar limit in its articles of association; however, Transocean, as part of its Corporate Governance Guidelines, has a general policy that a director must retire at the first annual meeting following his or her attainment of age 72.

Election of Directors

        GlobalSantaFe.    The GlobalSantaFe articles of association provide that directors may be elected at an annual general meeting by affirmative vote of a majority of the votes cast by the shareholders entitled to vote and present in person or by proxy at the meeting.

        Transocean.    The Transocean articles of association provide that directors may be elected at a general meeting by a plurality of the votes cast by the shareholders present in person or by proxy at the meeting. Transocean has, however, adopted a majority vote policy in the election of directors as part of its Corporate Governance Guidelines. This policy provides that the board may nominate only those candidates for director who have submitted an irrevocable letter of resignation which would be effective upon and only in the event that (1) such nominee fails to receive a sufficient number of votes from shareholders in an uncontested election and (2) the board accepts the resignation. If a nominee who has submitted such a letter of resignation does not receive more votes cast "for" than "against" the nominee's election, the Corporate Governance Committee must promptly review the letter of resignation and recommend to the board whether to accept the tendered resignation or reject it. The board must then act on the Corporate Governance Committee's recommendation within 90 days following the certification of the shareholder vote. The board must promptly disclose its decision regarding whether or not to accept the nominee's resignation letter.

Vacancies

        GlobalSantaFe.    Any vacancy on the board of directors of GlobalSantaFe, whether resulting from an increase in the size of its board of directors or otherwise, may be filled by a majority vote of the directors then in office, although less than a quorum, or by a sole remaining director.

        Transocean.    Prior to the second anniversary of the effective time of the Merger, any vacancy on the Transocean board of directors shall be filled as follows: if the vacancy relates to a director who was previously a Transocean director, then by the other Transocean directors, and if the vacancy relates to a director who was previously a GlobalSantaFe director, then by the other GlobalSantaFe directors. See "The Transactions—Amendment and Restatement of Transocean's Memorandum of Association and Articles of Association" for a further discussion. After such time, and under Transocean's articles of association in effect prior to the effective time of the Merger, any vacancy on the board of directors of Transocean, whether resulting from an increase in the size of its board of directors or otherwise, may be filled by a majority vote of the directors then in office, although less than a quorum, or by a sole remaining director.

Officers

        GlobalSantaFe.    The GlobalSantaFe board of directors may appoint the officers of GlobalSantaFe, who shall hold office until such time as determined by the GlobalSantaFe board of directors.

161


        Transocean.    Until the second anniversary of the effective time of the Merger, Robert L. Long will serve as the Chief Executive Officer of Transocean and Jon A. Marshall will serve as the President and Chief Operating Officer of Transocean unless such person is removed or replaced by the affirmative vote of two-thirds of the entire board of directors of Transocean. See "The Transactions—Amendment and Restatement of Transocean's Memorandum of Association and Articles of Association" for a further discussion. After such time, and under Transocean's articles of association in effect prior to the effective time of the Merger, the Transocean board of directors may appoint these officers of Transocean, who shall hold office until such time as determined by the Transocean board of directors. The Transocean board of directors may appoint other officers of Transocean, who shall hold office until such time as determined by the Transocean board of directors.

Shareholder Approval of Sales of Substantially All Assets.

        GlobalSantaFe.    GlobalSantaFe's articles of association provide that, in order for it to sell, lease or exchange all or substantially all of its property or assets, it must first obtain the approval of its board of directors and a majority of the votes cast by its shareholders at a general meeting.

        Transocean.    Transocean's articles of association provide that, in order for it to sell, lease or exchange all or substantially all of its property or assets, it must first obtain the approval of its board of directors and the approval of the holders of at least a majority of its issued shares generally entitled to vote.

Special Vote Required for Combinations with Interested Shareholders

        GlobalSantaFe.    Neither Cayman Islands law nor GlobalSantaFe's memorandum and articles of association require special votes for combinations with interested shareholders.

        Transocean.    Transocean's articles of association provide that, in general, it may not engage in a business combination with an interested shareholder for a period of three years after the time of the transaction in which the person became an interested shareholder. The prohibition on business combinations with interested shareholders does not apply in some cases, including if:


Issuance, Registration and Transfer of Shares

        GlobalSantaFe.    GlobalSantaFe's memorandum and articles of association do not contain provisions related to the matters described below, except that GlobalSantaFe's articles of association expressly provide for the issuance of fractional shares.

        Transocean.    The Transocean board of directors may, in its discretion, decline to register any transfer of any share (subject to any NYSE rules governing transfer of stocks). The Transocean board

162



of directors may suspend the registration of share transfers for 30 days in any year. Transocean's articles of association expressly provide for the issuance of fractional shares up to three decimal places. The articles of association also provide for actions which the board may take when shareholders become entitled to fractions of a share (including the sale of fractions of a share or rounding up shares to the nearest whole number).

Share Certificates

        GlobalSantaFe.    GlobalSantaFe currently permits its shareholders to have their shares represented in certificated form.

        Transocean.    If the amended and restated articles are approved by Transocean's shareholders, Transocean shareholders will not be entitled to share certificates unless its board of directors deems otherwise. Under Transocean's articles in effect prior to the Merger, shares are represented in certificated form unless its board of directors deems otherwise.

Shareholder Proposals

        GlobalSantaFe.    A GlobalSantaFe shareholder desiring to submit a proposal for consideration by the shareholders at any general meeting must given written notice of such intent, which notice must be received by the secretary of GlobalSantaFe no later than (1) with respect to an annual general meeting, 90 days in advance of the anniversary date of the immediately preceding annual meeting and (2) with respect to an extraordinary general meeting, the close of business on the tenth day following the date on which notice of such meeting is sent or given to its shareholders.

        Transocean.    A Transocean shareholder desiring to submit a proposal for consideration by the shareholders at any annual general meeting must given written notice of such intent, which notice must be received by the secretary of Transocean no later than 90 days in advance of the anniversary date of the immediately preceding annual meeting. If the date of the annual general meeting is more than 30 days before or after such anniversary date, such written notice must instead be received by the secretary of Transocean by the close of business on the tenth day following the date on which Transocean first makes public disclosure of the meeting date.

Special Meetings of Shareholders

        GlobalSantaFe.    GlobalSantaFe's articles of association provide that an extraordinary general meeting of its shareholders may also be called upon the written request of shareholders holding at least 35% of the outstanding ordinary shares generally entitled to vote. GlobalSantaFe's articles of association provide that a special/class meeting may also be called upon a written request of 25% of the outstanding shares of that class.

        Transocean.    Transocean's articles of association expressly provide that no shareholders have any right to request an extraordinary general meeting.

Record Dates for Shareholder Meetings

        GlobalSantaFe.    GlobalSantaFe's articles of association provide that the record date for any general shareholder meeting may be at most 40 days prior to that meeting.

        Transocean.    Transocean's articles of association provide that the record date for any general shareholder meeting may be at most 60 days prior to that meeting.

163



Limitation of Liability and Indemnification

        GlobalSantaFe.    The GlobalSantaFe articles of association provide that GlobalSantaFe will indemnify to the fullest extent permitted by law any person who is a party, or threatened to be made a party, to any action or other proceeding by reason of having acted as a director, officer, employee or in any other capacity for or on behalf of GlobalSantaFe.

        Transocean.    The Transocean articles of association provide that no director will be personally liable to the company or shareholders except in the case of breach of the director's duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or for transactions from which the director derived an improper personal benefit. In addition, the Transocean articles of association provide that Transocean will indemnify to the fullest extent permitted by law any person who is a party, or threatened to be made a party, to any action or other proceeding by reason of having acted as a director or officer of Transocean, or in any other capacity for or on behalf of Transocean while serving as an officer or director of Transocean, or (in the discretion of the Transocean board of directors) an employee or agent of Transocean.

Amendment of Governing Documents

        GlobalSantaFe.    The GlobalSantaFe articles of association may be amended at any time by the vote of two-thirds of the shares present in person or by proxy at a meeting of the GlobalSantaFe shareholders.

        Transocean.    The Transocean articles of association may be amended at any time by the vote of two-thirds of the shares present in person or by proxy at a meeting of the Transocean shareholders at which a quorum is present. Under the Transocean articles of association, generally the presence of Transocean shareholders in person or by proxy holding a majority of issued shares generally entitled to vote at the shareholder meeting constitutes a quorum. Transocean's articles of association provide that, in order for certain articles to be amended, particular quorum rules must be met. Specifically, the Transocean articles of association provide that in order to amend, vary, suspend or disapply the special governance provisions that apply until the second anniversary of the effective time of the Merger or the provisions relating to general meetings, proceedings at general meetings, the number and term of directors or certain business combinations, at least 95% of the shares entitled to vote must be present in order to establish a quorum unless a majority of the Transocean board of directors (or two-thirds of the whole Transocean board of directors with respect to the special governance provisions) has recommended to the shareholders to vote in favor of the amendment. In addition, with respect to a special resolution to amend, vary, suspend or disapply the provisions relating to business combinations with interested persons, if (1) the recommendation of the Transocean board of directors was made at a time when the majority of the Transocean board of directors were directors prior to the time that any person became an interested person or were recommended for election or elected to succeed such directors by a majority of such directors or (2) the amendment will not be effective for a period of 12 months after the passage of the special resolution and will continue to apply to any person who was an interested person at the time of the passing of the special resolution, then the presence of Transocean shareholders in person or by proxy holding a majority of issued shares generally entitled to vote at the shareholder meeting constitutes a quorum.

Inspection of Books and Records

        GlobalSantaFe.    Upon written demand under oath stating the purpose thereof, any GlobalSantaFe shareholder may review for any proper purpose, during usual hours for business, the books and records of GlobalSantaFe. A proper purpose is defined to mean a purpose reasonably related to such person's interest as a shareholder.

164


        Transocean.    Transocean's articles of association allow an agent of a shareholder to examine the books and records of Transocean for any proper purpose, provided that written authorization accompanies the demand under oath. A proper purpose is defined to mean a purpose reasonably related to such person's interest as a shareholder. The articles of association also provide that the Transocean board of directors may establish procedures for and limitations on the investigation of the company's books and records for the following purposes:

165



INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMS

        The consolidated financial statements and schedule of Transocean Inc. and subsidiaries as of December 31, 2006 and 2005, and for each of the three years in the period ended December 31, 2006, and management's assessment of the effectiveness of internal control over financial reporting, incorporated by reference in this joint proxy statement, have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in its reports thereon, and are incorporated herein.

        The consolidated financial statements and schedule of GlobalSantaFe and subsidiaries as of December 31, 2006 and 2005, and for each of the three years in the period ended December 31, 2006 and management's assessment of the effectiveness of internal control over financial reporting (which is included in Management's Report on Internal Control over Financial Reporting) as of December 31, 2006, incorporated by reference in this joint proxy statement, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report therein.

        With respect to the unaudited condensed financial information of GlobalSantaFe and subsidiaries for the three-month period ended March 31, 2007 and 2006, and for the three month and six-month periods ended June 30, 2007 and 2006, incorporated by reference in this joint proxy statement, PricewaterhouseCoopers LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated May 4, 2007, for the three-month period ended March 31, 2007 and 2006, and August 3, 2007, for the three-month and six-month periods ended June 30, 2007 and 2006, incorporated by reference herein, state that they did not audit and they do not express an opinion on that unaudited condensed financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied.


LEGAL MATTERS

        Walkers, Cayman Islands will pass upon certain legal matters in connection with the Transactions for Transocean. Baker Botts L.L.P., Houston, Texas, will pass upon certain U.S. federal income tax consequences of the Transactions for Transocean. Skadden, Arps, Slate, Meagher & Flom LLP, New York, New York, will pass upon certain U.S. federal income tax consequences of the Transactions for GlobalSantaFe.


FUTURE SHAREHOLDER PROPOSALS

        Rule 14a-8 under the Securities Exchange Act of 1934 addresses when a company must include a shareholder's proposal in its proxy statement and identify the proposal in its form of proxy when the company holds an annual or special meeting of stockholders. In general, under Rule 14a-8 a proposal for a regularly scheduled annual meeting must be received at the company's principal executive offices not less than 120 calendar days before the date of the company's proxy statement released to shareholders in connection with the previous year's annual meeting. For a special meeting, the deadline is a reasonable time before the company begins to print and mail its proxy materials. In addition to complying with the applicable deadline, shareholder proposals must also be otherwise eligible for inclusion.

Transocean

        Transocean has already held its 2007 annual meeting. In order for proposals to be considered for inclusion in the proxy statement and proxy card relating to the 2008 annual general meeting of shareholders of Transocean, those proposals must be received at Transocean's principal executive offices, 4 Greenway Plaza, Houston, Texas 77046, by no later than November 27, 2007. However, if the

166



date of the 2008 annual general meeting changes by more than 30 days from the anniversary date of the 2007 annual general meeting, the deadline is a reasonable time before Transocean begins to print and mail its proxy materials. Transocean will notify shareholders of this deadline in a Quarterly Report on Form 10-Q or in another communication to shareholders. Shareholder proposals must also be otherwise eligible for inclusion.

        If you desire to bring a matter before an annual meeting of Transocean and the proposal is submitted outside the process of Rule 14a-8, you must follow the procedures set forth in Transocean's articles of association. The articles of association provide generally that if you desire to propose any business at an annual meeting of shareholders, you must give Transocean written notice not less than 90 days prior to the anniversary of the originally scheduled date of the immediately preceding annual meeting. The deadline under Transocean's articles of association for submitting proposals will be February 10, 2008, for the 2008 annual meeting unless it is more than 30 days before or after the anniversary of the 2007 annual meeting. However, if the date of the forthcoming annual meeting is more than 30 days before or after that anniversary date, the deadline is the close of business on the tenth day after Transocean publicly discloses the meeting date. Your notice must set forth:

        If you desire to nominate directors at an annual meeting, you must give Transocean written notice within the time period described in the preceding paragraph. If you desire to nominate directors at a special meeting at which the board of directors has determined that directors will be elected, you must give Transocean written notice by the close of business on the tenth day following Transocean's public disclosure of the meeting date. Your notice must set forth:

167


        The chairman of the meeting may refuse to transact any business or to acknowledge the nomination of any person if you fail to comply with the foregoing procedures.

        You may obtain a copy of Transocean's articles of association, in which these procedures are set forth, upon written request to Eric B. Brown, Secretary, Transocean Inc., 4 Greenway Plaza, Houston, Texas 77046, or see "Where You Can Find More Information."

GlobalSantaFe

        If the Transactions are consummated, GlobalSantaFe will not have a 2008 annual general meeting. However, if the Transactions are not completed, GlobalSantaFe expects to hold a 2008 annual general meeting.

        The U.S. federal securities laws provide each shareholder with a limited right to propose for inclusion in GlobalSantaFe's proxy statement a single proposal for action to be taken at the annual general meeting. Proposals intended to be presented at the GlobalSantaFe annual general meeting to be held in 2008 and otherwise eligible must be directed to GlobalSantaFe's Secretary at 15375 Memorial Drive, Houston, Texas 77079, and must be received no later than January 2, 2008.

        If a GlobalSantaFe shareholder desires to bring a matter before an annual general meeting and the matter is not eligible or is not timely submitted for inclusion in GlobalSantaFe's proxy statement, or if the shareholder desires to nominate a person to be a director, the shareholder must follow the procedures outlined in GlobalSantaFe's articles of association. The articles of association of GlobalSantaFe require timely notice in writing of the matter or nomination, and receipt of the written notice by GlobalSantaFe's secretary not later than the close of business on the 90th day prior to the anniversary of the originally scheduled date of the preceding year's annual general meeting. The deadline for delivery and receipt of such notices for the 2008 Annual General Meeting of Shareholders is the close of business on March 10, 2008. A copy of GlobalSantaFe's articles of association is available upon request from GlobalSantaFe's secretary at 15375 Memorial Drive, Houston, Texas 77079.

168



HOUSEHOLDING

        The SEC permits a single set of annual reports and proxy statements to be sent to any household at which two or more shareholders reside if they appear to be members of the same family. Each shareholder continues to receive a separate proxy card. This procedure, referred to as householding, reduces the volume of duplicate information shareholders receive and reduces mailing and printing expenses. A number of brokerage firms have instituted householding.

        As a result, if you hold your shares through a broker and you reside at an address at which two or more shareholders reside, you will likely be receiving only one annual report and one proxy statement unless any shareholder at that address has given the broker contrary instructions. However, if any such beneficial shareholder residing at such an address wishes to receive a separate annual report or proxy statement in the future, or if any such beneficial shareholder that elected to continue to receive separate annual reports or proxy statements wishes to receive a single annual report or proxy statement in the future, that shareholder should contact its broker or send a request to Transocean's corporate secretary at Eric B. Brown, Secretary, Transocean Inc., 4 Greenway Plaza, Houston, Texas 77046, telephone number (713) 232-7500. Transocean will deliver, promptly upon written or oral request to the corporate secretary, a separate copy of the Transocean 2006 annual report and this joint proxy statement to a beneficial shareholder at a shared address to which a single copy of the documents was delivered.

169

Please call the SEC at 1-800-SEC-0330 for further information on the public reference rooms. These SEC filings are also available to the public on the SEC's web site at: http://www.sec.gov.

Some documents or information, such as that called for by Item 7.01 of Form 8-K, are deemed furnished and not filed in accordance with SEC rules. None of those documents and none of that information is incorporated by reference into this joint proxy statement. The information that Transocean and GlobalSantaFe incorporate by reference is considered to be part of this joint proxy statement. Information that Transocean and GlobalSantaFe file later with the SEC will automatically update and supersede this information.

        Transocean and GlobalSantaFe incorporate by reference the documents listed below and any filings Transocean or GlobalSantaFe will make with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 (excluding any information "furnished" but not "filed") following the date of this document, but prior to the date of their respective shareholder meeting:

        In order to ensure timely delivery of these documents, you should make such request by                        , 2007.

        Neither Transocean nor GlobalSantaFe has authorized anyone to give any information or make any representation about the Transactions or about the respective companies that differs from or adds to the information in this joint proxy statement or in the documents incorporated by reference. Therefore, you should not rely upon any information that differs from or is in addition to the information contained in this joint proxy statement or in the documents incorporated by reference.

AGREEMENT AND PLAN OF MERGER

        THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") dated as of July 21, 2007, is by and among Transocean Inc., a company incorporated under the laws of the Cayman Islands ("Transocean"), GlobalSantaFe Corporation, a company incorporated under the laws of the Cayman Islands ("GlobalSantaFe"), and Transocean Worldwide Inc., a company incorporated under the laws of the Cayman Islands and a direct wholly owned subsidiary of Transocean ("Merger Sub").

RECITALS

        A.    The Merger and the Reclassification. GlobalSantaFe and Merger Sub intend to effect the Merger described in Section 1.1 and Transocean intends to effect the Reclassification described in Section 1.2 pursuant to schemes of arrangement, each under Section 86 of The Companies Law (2007 Revision) of the Cayman Islands (the "Companies Law"), so that GlobalSantaFe will merge with Merger Sub, and Transocean will reclassify its outstanding Transocean Ordinary Shares into the number of new Transocean Ordinary Shares and the amount of cash described in Section 4.1.

        B.    Intended U.S. Tax Consequences of the Merger. It is intended that, for United States federal income tax purposes, the Merger shall qualify as a reorganization under Section 368(a) of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), and the regulations promulgated thereunder, and this Agreement is hereby adopted as a plan of reorganization for purposes of Section 368(a) of the Code and the regulations promulgated thereunder.

        C.    Intended U.S. Accounting Treatment. The parties to this Agreement intend that the Merger be treated as the purchase of GlobalSantaFe by Transocean for U.S. generally accepted accounting principles ("GAAP").

        NOW, THEREFORE, in consideration of the foregoing, and of the representations, warranties, covenants and agreements contained herein, the parties hereto hereby agree as follows:

ARTICLE 1

THE MERGER AND THE RECLASSIFICATION BY WAY
OF SCHEMES OF ARRANGEMENT

        Section 1.1    The Merger.    Subject to the terms and conditions of this Agreement, at the Effective Time, GlobalSantaFe shall merge with Merger Sub by way of a scheme of arrangement qualifying as an amalgamation under the Companies Law (the "Merger"). In the Merger, as a result of the operation of the Companies Law and the scheme of arrangement described in Section 7.15(b), and simultaneously at the Effective Time, all of the assets, undertaking and liabilities of GlobalSantaFe will, in accordance with Section 87 of the Companies Law, become the assets, undertaking and liabilities of Merger Sub, and GlobalSantaFe will cease its separate legal existence for all purposes. Merger Sub shall be the surviving entity following the Merger (sometimes hereinafter referred to as the "Surviving Entity"). The Merger shall have the effects specified herein pursuant to Section 87 of the Companies Law and shall be deemed to have the effects of a merger of a corporation under the General Corporation Law of the State of Delaware (the "DGCL"), meaning that the separate existence of GlobalSantaFe shall cease, and Merger Sub shall possess all the rights, privileges, powers and franchises as well of a public as of a private nature, and shall be subject to all the restrictions, disabilities and duties, of each of Merger Sub and GlobalSantaFe; and all and singular, the rights, privileges, powers and franchises of each of said constituent companies, and all property, real, personal and mixed, and all debts due to any of said constituent companies on whatever account, as well as for share subscriptions as all other things in action or belonging to each of such companies shall be vested in Merger Sub; and all property, rights, privileges, powers and franchises, and all and every other interest shall be thereafter as effectually the property of Merger Sub as they were of the two constituent companies, and the title to any real estate

A-1

        Section 4.2    Exchange of Certificates Representing Transocean Ordinary Shares and GlobalSantaFe Ordinary Shares and Cash Payments.    

        (a)   Prior to the Initial Effective Time, Transocean shall deposit, or shall cause to be deposited, with Transocean's transfer agent for Transocean Ordinary Shares or such other party reasonably satisfactory to Transocean and GlobalSantaFe (the "Exchange Agent"), for the benefit of the holders of

A-8



outstanding Transocean Ordinary Shares and GlobalSantaFe Ordinary Shares for exchange in accordance with this Article 4, certificates representing the Transocean Ordinary Shares to be issued pursuant to Section 4.1 and delivered pursuant to this Section 4.2 and cash to be paid pursuant to Section 4.1 and delivered pursuant to this Section 4.2 in exchange for outstanding Transocean Ordinary Shares and GlobalSantaFe Ordinary Shares. Transocean shall also provide the Exchange Agent immediately following the Effective Time cash sufficient to pay cash in lieu of fractional shares in accordance with Section 4.2(e). Such cash and certificates for Transocean Ordinary Shares together with any dividends or distributions with respect thereto are hereinafter referred to as the "Exchange Fund."

        (b)   Promptly after the Effective Time, Transocean shall cause the Exchange Agent to mail to each holder of record of one or more certificates ("Certificates") that immediately prior to the Effective Time represented Transocean Ordinary Shares or GlobalSantaFe Ordinary Shares: (A) a letter of transmittal (the "Letter of Transmittal") which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Transocean may reasonably specify and (B) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing Transocean Ordinary Shares, cash (including cash in lieu of fractional shares in accordance with Section 4.2(e)) and any unpaid dividends and distributions on Transocean Ordinary Shares in accordance with Section 4.2(c). Upon surrender of a Certificate for cancellation to the Exchange Agent together with such Letter of Transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor (x) a certificate representing that number of whole Transocean Ordinary Shares and (y) a check representing the aggregate amount of the Transocean Cash Consideration or the GlobalSantaFe Cash Consideration, as applicable, and cash in lieu of fractional shares, if any, and unpaid dividends and distributions, if any, which such holder has the right to receive pursuant to the provisions of this Article 4, after giving effect to any required withholding tax, and the Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued on the cash in lieu of fractional shares and unpaid dividends and distributions, if any, payable to holders of Certificates. In the event of a transfer of ownership of Transocean Ordinary Shares which is not registered in the transfer records of Transocean, or a transfer of ownership of GlobalSantaFe Ordinary Shares that is not registered in the transfer records of GlobalSantaFe, a certificate representing the proper number of Transocean Ordinary Shares together with a check representing the amount of the Transocean Cash Consideration or the GlobalSantaFe Cash Consideration, as applicable, and cash in lieu of fractional shares, if any, may be issued to such a transferee if the Certificate representing such Transocean Ordinary Shares or GlobalSantaFe Ordinary Shares, as the case may be, is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid.

        (c)   Notwithstanding any other provisions of this Agreement, no dividends or other distributions declared or made after the Effective Time with respect to Transocean Ordinary Shares with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the Transocean Ordinary Shares represented by such Certificate as a result of the conversion provided in Section 4.1(a) or 4.1(b) until such Certificate is surrendered as provided herein. Subject to the effect of Applicable Laws, following surrender of any such Certificate, there shall be paid to the holder of the Certificates so surrendered, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore payable and not paid with respect to the number of whole Transocean Ordinary Shares issued pursuant to Section 4.1, less the amount of any withholding taxes, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole Transocean Ordinary Shares, less the amount of any withholding taxes.

A-9


        (d)   (i) At or after the Effective Time, Transocean shall pay from funds on hand at the Effective Time any dividends or make other distributions with a record date prior to the Effective Time that may have been declared or made by Transocean on Transocean Ordinary Shares which remain unpaid at the Effective Time, and after the Effective Time, there shall be no transfers on the stock transfer books of Transocean of the Transocean Ordinary Shares which were outstanding immediately prior to the Effective Time and (ii) at or after the Effective Time, Transocean shall pay from funds on hand at the Effective Time any dividends or make other distributions with a record date prior to the Effective Time that may have been declared or made by GlobalSantaFe on GlobalSantaFe Ordinary Shares which remain unpaid at the Effective Time, and after the Effective Time, the stock transfer books of GlobalSantaFe shall be closed and there shall be no transfers of the GlobalSantaFe Ordinary Shares which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to Transocean, the presented Certificates shall be canceled and exchanged for certificates representing Transocean Ordinary Shares and the amount of the Transocean Cash Consideration or the GlobalSantaFe Cash Consideration, as applicable, and cash in lieu of fractional shares, if any, deliverable in respect thereof pursuant to this Agreement in accordance with the procedures set forth in this Article 4. Certificates surrendered for exchange by any Person constituting an "affiliate" of Transocean or GlobalSantaFe for purposes of Rule 145(c) under the Securities Act of 1933, as amended (the "Securities Act"), shall not be exchanged until Transocean or GlobalSantaFe, as applicable, has received a written agreement from such Person as provided in Section 7.11, unless the parties have adjusted Section 7.11 to eliminate the requirements of Section 7.11 with respect to such agreement in accordance with the last sentence of Section 7.11.

        (e)   No fractional Transocean Ordinary Shares shall be issued pursuant hereto. In lieu of the issuance of any fractional Transocean Ordinary Shares pursuant to Section 4.1(b), cash adjustments provided by Transocean will be paid to holders in respect of any fractional Transocean Ordinary Shares that would otherwise be issuable, and the amount of such cash adjustment shall be equal to the product obtained by multiplying (i) the fractional share interest to which such holder would otherwise be entitled by (ii) the Transocean Ordinary Share Price. The "Transocean Ordinary Share Price" shall mean the average of the per share closing prices of the Transocean Ordinary Shares as reported on the consolidated transaction reporting system for securities traded on the New York Stock Exchange, Inc. ("NYSE") (as reported in the New York City edition of The Wall Street Journal or, if not reported thereby, another authoritative source) for the 20 consecutive trading days ending on the fifth trading day prior to the Closing Date, appropriately adjusted for any stock splits, reverse stock splits, stock dividends, recapitalizations or other similar transactions.

        (f)    Any portion of the Exchange Fund (including the proceeds of any investments thereof and any certificates for Transocean Ordinary Shares) that remains undistributed to the former shareholders of Transocean and GlobalSantaFe one year after the Effective Time shall be delivered to Transocean. Any former shareholders of Transocean or GlobalSantaFe who have not theretofore complied with this Article 4 shall thereafter look only to Transocean for delivery of certificates representing their Transocean Ordinary Shares and the amount of the Transocean Cash Consideration or the GlobalSantaFe Cash Consideration, as applicable, cash in lieu of fractional shares, if any, and any unpaid dividends and distributions on the Transocean Ordinary Shares deliverable to such former shareholders pursuant to this Agreement.

        (g)   None of Transocean, GlobalSantaFe, the Surviving Entity, the Exchange Agent or any other Person shall be liable to any Person for any portion of the Exchange Fund properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

        (h)   In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Transocean, the posting by such Person of a bond in such reasonable amount as Transocean may direct as indemnity against any claim that may be made against it with respect to such Certificate,

A-10



the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate certificates representing the Transocean Ordinary Shares and the amount of the Transocean Cash Consideration or the GlobalSantaFe Cash Consideration, as applicable, cash in lieu of fractional shares, if any, and unpaid dividends and distributions on Transocean Ordinary Shares, as provided in Section 4.2(c), deliverable in respect thereof pursuant to this Agreement.

        (i)    Notwithstanding anything to the contrary contained in this Agreement, the parties intend that Transocean be permitted to implement a direct registration system in accordance with NYSE rules and Applicable Laws for the Transocean Ordinary Shares at the Closing, and if Transocean determines to implement such a system at such time, all or any portion of the Transocean Ordinary Shares issued in connection with this Agreement may be in uncertificated book entry form unless a physical certificate is requested in writing by a holder of Certificates.

        Section 4.3    Adjustment of Share Consideration.    If, between the date of this Agreement and the Effective Time (as permitted by Section 7.l), the outstanding Transocean Ordinary Shares or the outstanding GlobalSantaFe Ordinary Shares shall have been increased, decreased, changed into or exchanged for a different number of shares or different class, in each case, by reason of any reclassification, recapitalization, stock split, split-up, combination or exchange of shares or a stock dividend or dividend payable in other securities shall be declared with a record date within such period, or any similar event shall have occurred, the applicable Transocean Share Consideration or GlobalSantaFe Share Consideration shall be appropriately adjusted to provide to the holders of Transocean Ordinary Shares or GlobalSantaFe Ordinary Shares, as the case may be, the same economic effect as contemplated by this Agreement prior to such event. Notwithstanding anything in this Agreement to the contrary, the Reclassification shall not result in any adjustment pursuant to this Section 4.3.

        Section 4.4    Rule 16b-3 Approval.    The Board of Directors of Transocean or a committee thereof, at or prior to the Effective Time, shall adopt resolutions specifically approving, for purposes of Rule 16b-3 ("Rule 16b-3") under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the receipt, pursuant to Section 4.1, of Transocean Ordinary Shares, and of options to acquire Transocean Ordinary Shares, by executive officers or directors of Transocean and GlobalSantaFe who become executive officers or directors of Transocean subject to Rule 16b-3.

A-11



of the properties owned or leased by it therein or in which the transaction of its business makes such qualification necessary, except where the failure to be so qualified does not and is not reasonably likely to have, individually or in the aggregate, a GlobalSantaFe Material Adverse Effect (as defined in Section 10.9). GlobalSantaFe has all requisite corporate power and authority to own, operate and lease its properties and to carry on its business as now conducted.

This Agreement has been duly and validly executed and delivered by GlobalSantaFe and, assuming due authorization, execution and delivery of this Agreement by Transocean, constitutes the valid and legally binding obligation of GlobalSantaFe, enforceable against GlobalSantaFe in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to creditors' rights and general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity).

        Section 5.3    Capitalization.    As of the date of this Agreement, the authorized share capital of GlobalSantaFe consists of 600,000,000 GlobalSantaFe Ordinary Shares. As of June 30, 2007, there were 226,981,786 GlobalSantaFe Ordinary Shares issued and outstanding, including no restricted shares, and 3,123,706 GlobalSantaFe Ordinary Shares reserved for issuance upon exercise of outstanding GlobalSantaFe Options, 1,284,335 GlobalSantaFe Ordinary Shares reserved for issuance upon vesting of GlobalSantaFe Stock Units, 998,429 GlobalSantaFe Ordinary Shares reserved for issuance upon exercise of GlobalSantaFe SARs and 129,056 GlobalSantaFe Ordinary Shares held by a Subsidiary of GlobalSantaFe.

As of the date of this Agreement, except as set forth in this Section 5.3, (x) there are no outstanding or authorized capital shares and there are no options, warrants, calls, subscriptions, convertible securities, preemptive rights or other rights, agreements, claims or commitments which obligate GlobalSantaFe or any of its Subsidiaries to issue, transfer or sell any capital shares or other voting securities or other equity interest in GlobalSantaFe or any of its Subsidiaries or securities convertible into or exchangeable for such shares, securities or equity interests, (y) there are no outstanding or authorized contractual obligations of GlobalSantaFe or any of its Subsidiaries to repurchase, redeem or otherwise acquire any capital shares or other voting securities of or other equity interest in GlobalSantaFe or any of its Subsidiaries or any such securities or agreements listed in clause (x) of this sentence, and (z) there are no voting trusts or similar agreements to which GlobalSantaFe or any of its Subsidiaries is a party with respect to the voting of any capital shares or other voting securities of or other equity interest in GlobalSantaFe or any of its Subsidiaries.

All of the outstanding shares of capital stock of, or other ownership interests in, each of GlobalSantaFe's Significant Subsidiaries are duly authorized, validly issued, fully paid and nonassessable and, as of the date of this Agreement, are owned, directly or indirectly, by GlobalSantaFe free and clear of all mortgages, deeds of trust, liens, security interests, pledges, leases, conditional sale contracts, charges, privileges, easements, rights of way, reservations, options, rights of first refusal and other encumbrances ("Liens").

A-22



the localities in which, all or any portion of their respective businesses is conducted, other than any such limitation that is not material to GlobalSantaFe and its Subsidiaries, taken as a whole, and will not be material to Transocean and its Subsidiaries, taken as a whole, following the Effective Time, (ii) any drilling unit construction or conversion contract with respect to which the drilling unit has not been delivered and paid for, (iii) any drilling contracts of one year or greater remaining duration, including fixed price customer options, (iv) any contract or agreement for the borrowing of money with a borrowing capacity or outstanding indebtedness of $50 million or more, (v) any employment agreement between GlobalSantaFe or any of its Subsidiaries, on the one hand, and any of GlobalSantaFe's officers and key employees, on the other hand, (vi) any agreement which, upon the consummation of the Merger or any other transaction contemplated by this Agreement, will (either alone or upon the occurrence of any additional acts or events, including the passage of time) result in any payment or benefit (whether of severance pay or otherwise) becoming due, or the acceleration or vesting of any right to any payment or benefits, from Transocean or GlobalSantaFe or any of their respective Subsidiaries to any officer, director, consultant or employee of any of the foregoing, (vii) any agreement which is a material joint venture agreement, joint operating agreement, partnership agreement or other similar contract or agreement involving a sharing of profits and expenses with one or more third Persons, (viii) any agreement the benefits of which will be increased, or the vesting of the benefits of which will be accelerated, by the occurrence of any of the transactions contemplated by this Agreement, or the value of any of the benefits of which will be calculated on the basis of any of the transactions contemplated by this Agreement (including any stock option plan, stock appreciation rights plan, restricted stock plan or stock purchase plan) or (ix) any "material contract" (as such term is defined in Item 601(b)(10) of Regulation S-K of the SEC). Each contract, arrangement, commitment or understanding of the type described in this Section 5.23(a), whether or not included as an exhibit to any GlobalSantaFe Report or included in Section 5.23 of the GlobalSantaFe Disclosure Letter, is referred to herein as a "GlobalSantaFe Material Contract," and for purposes of Section 7.1 and the bringdown of Section 5.23(b) pursuant to Section 8.3(a), "GlobalSantaFe Material Contract" shall include any such contract, arrangement, commitment or understanding that is entered into after the date of this Agreement.

        (b)   Each GlobalSantaFe Material Contract is, to the knowledge of GlobalSantaFe, in full force and effect, and GlobalSantaFe and each of its Subsidiaries have in all material respects performed all obligations required to be performed by them to date under each GlobalSantaFe Material Contract to which it is a party, except where such failure to be binding or in full force and effect or such failure to perform does not and is not reasonably likely to create, individually or in the aggregate, a GlobalSantaFe Material Adverse Effect. Except for such matters as do not and are not reasonably likely to have, individually or in the aggregate, a GlobalSantaFe Material Adverse Effect, neither GlobalSantaFe nor any of its Subsidiaries (x) knows of, or has received written notice of, any breach of or violation or default under (nor, to the knowledge of GlobalSantaFe, does there exist any condition which with the passage of time or the giving of notice or both would result in such a violation or default under) any GlobalSantaFe Material Contract or (y) has received written notice of the desire of the other party or parties to any such GlobalSantaFe Material Contract to exercise any rights such party has to cancel, terminate or repudiate such contract or exercise remedies thereunder. Except as would not be reasonably likely to have, individually or in the aggregate, a GlobalSantaFe Material Adverse Effect, the consummation of the transactions contemplated by this Agreement will not breach or violate any GlobalSantaFe Material Contract or permit any other party to a GlobalSantaFe Material Contract to exercise rights adverse to GlobalSantaFe. Each GlobalSantaFe Material Contract is enforceable by GlobalSantaFe or a Subsidiary of GlobalSantaFe in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to creditors' rights and general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity), except where such unenforceability is not reasonably likely to create, individually or in the aggregate, a GlobalSantaFe Material Adverse Effect.

GlobalSantaFe and each of its Subsidiaries have, and will have, duly performed all of their respective obligations under the Derivative Transactions to the extent that such obligations to perform have accrued, and, to the knowledge of GlobalSantaFe, there are and will be no breaches, violations, collateral deficiencies, requests for collateral or demands for payment, or defaults or allegations or assertions of such by any party thereunder.

        Section 5.26    Disclosure Controls and Procedures.    GlobalSantaFe has established and maintains "disclosure controls and procedures" (as defined in Rules 13a-14(c) and 15d-14(c) of the Exchange Act) that are reasonably designed to ensure that all material information (both financial and non-financial) required to be disclosed by GlobalSantaFe in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that all such information is accumulated and communicated to GlobalSantaFe's management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the Chief Executive Officer and Chief Financial Officer of GlobalSantaFe required under the Exchange Act with respect to such reports. Except as set forth in GlobalSantaFe's Annual Report on Form 10-K for the fiscal year ended December 31, 2006, since January 1, 2006, neither GlobalSantaFe nor its independent auditors have identified any "significant deficiencies" or "material weaknesses" in GlobalSantaFe's or any of its Subsidiaries' internal controls as contemplated under Section 404 of the Sarbanes-Oxley Act.

        Section 5.27    Affiliate Transactions.    There are no material agreements, contracts, transfers of assets or liabilities or other commitments or transactions (other than GlobalSantaFe Benefit Plans described in Section 5.11 of the GlobalSantaFe Disclosure Letter), whether or not entered into in the ordinary course of business, to or by which GlobalSantaFe or any of its Subsidiaries, on the one hand,

A-24



and any of their respective Affiliates (other than GlobalSantaFe or any of its direct or indirect wholly owned Subsidiaries) on the other hand, are or have been a party or otherwise bound or affected, and that (a) are currently pending, in effect or have been in effect at any time since December 31, 2005 or (b) involve continuing liabilities and obligations that, individually or in the aggregate, have been, are or will be material to GlobalSantaFe and its Subsidiaries taken as a whole. "Affiliate" means, as to any specified Person, any other Person that, directly or indirectly through one or more intermediaries or otherwise, controls, is controlled by or is under common control with the specified Person. As used in this definition, "control" means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of a Person (whether through ownership of capital stock of that Person, by contract or otherwise).

        Section 5.28    Disclaimer.    

        (a)   Except for the representations and warranties contained in this Article V of this Agreement, Transocean acknowledges that neither GlobalSantaFe nor any other Person on behalf of GlobalSantaFe makes any other express or implied representation or warranty with respect to GlobalSantaFe with respect to any other information provided to Transocean. Without limiting the generality of the foregoing, neither GlobalSantaFe nor any other Person will have or be subject to any liability or indemnification obligation to Transocean or any other Person resulting from the distribution to Transocean, or use by Transocean of, any such information, including any information, documents, projections, forecasts or other material made available to Transocean in certain "data rooms" or management presentations in expectation of the transactions contemplated by this Agreement.

        (b)   In connection with investigation by Transocean of GlobalSantaFe and its Subsidiaries, Transocean has received or may receive from GlobalSantaFe and/or GlobalSantaFe's Subsidiaries certain projections, forward-looking statements and other forecasts and certain business plan information. Transocean acknowledges that there are uncertainties inherent in attempting to make such estimates, projections and other forecasts and plans, that Transocean is familiar with such uncertainties, that Transocean is taking full responsibility for making its own evaluation of the adequacy and accuracy of all estimates, projections and other forecasts and plans so furnished to it (including the reasonableness of the assumptions underlying such estimates, projections, forecasts or plans), and that, absent fraud or willful misrepresentation, Transocean shall have no claim against anyone with respect thereto. Accordingly, Transocean acknowledges that GlobalSantaFe makes no representation or warranty with respect to such estimates, projections, forecasts or plans (including the reasonableness of the assumptions underlying such estimates, projections, forecasts or plans).

        (c)   There are no liens for taxes in amounts reasonably likely to have a Transocean Material Adverse Effect (other than statutory liens for taxes not yet due and payable or the amount or validity of which is being contested in good faith by appropriate proceedings) upon any of the assets of Transocean or any of its Subsidiaries.

        (a)   Except for such matters as do not and are not reasonably likely to have, individually or in the aggregate, a Transocean Material Adverse Effect, Transocean and its Subsidiaries maintain insurance coverage with financially responsible insurance companies in such amounts and against such losses as are customary in the international offshore drilling business as of the date hereof.

        (b)   Except for such matters as do not and are not reasonably likely to have, individually or in the aggregate, a Transocean Material Adverse Effect, no event relating specifically to Transocean or its Subsidiaries (as opposed to events affecting the drilling service industry in general) has occurred that is reasonably likely, after the date of this Agreement, to result in an upward adjustment in premiums under any insurance policies they maintain. Excluding insurance policies that have expired and been replaced in the ordinary course of business, no excess liability, hull or protection and indemnity insurance policy has been canceled by the insurer within one year prior to the date hereof, and to Transocean's knowledge, no threat in writing has been made to cancel (excluding cancellation upon expiration or failure to renew) any such insurance policy of Transocean or any Subsidiary of Transocean during the period of one year prior to the date hereof. Prior to the date hereof, no event has occurred, including the failure by Transocean or any Subsidiary of Transocean to give any notice or information or by giving any inaccurate or erroneous notice or information, which materially limits or impairs the rights of Transocean or any Subsidiary of Transocean under any such excess liability, hull or protection and indemnity insurance policies.

        Section 6.17    No Brokers.    Transocean has not entered into any contract, arrangement or understanding with any Person which may result in the obligation of GlobalSantaFe or Transocean to pay any finder's fees, brokerage or other like payments in connection with the negotiations leading to this Agreement or the consummation of the transactions contemplated hereby, except that Transocean has retained Goldman, Sachs & Co. as its financial advisor, the arrangements with which have been disclosed in writing to GlobalSantaFe prior to the date hereof.

        (b)   The Board of Directors of Transocean has received the opinion of Goldman, Sachs & Co. to the effect that, as of the date of such opinion, and after taking into consideration the Reclassification, the GlobalSantaFe Merger Consideration to be received by holders of GlobalSantaFe Ordinary Shares is fair, from a financial point of view, to Transocean.

        Section 6.21    Ownership of Drilling Units.    

        (a)   As of the date hereof, Transocean or a Subsidiary of Transocean has good and marketable title to the drilling units listed in Transocean's most recent annual report on Form 10-K, in each case free and clear of all Liens except for (i) defects or irregularities of title or encumbrances of a nature that do not materially impair the ownership or operation of these assets and which have not had and are not reasonably likely to, individually or in the aggregate, have a Transocean Material Adverse Effect, (ii) Liens that secure obligations not yet due and payable or, if such obligations are due and have not been paid, Liens securing such obligations that are being diligently contested in good faith and by appropriate proceedings (any such contests involving an amount in excess of $25 million being described in the Transocean Disclosure Letter), (iii) Liens for taxes, assessments or other governmental charges or levies not yet due or which are being contested in good faith, (iv) Liens in connection with workmen's compensation, unemployment insurance or other social security, old age pension or public liability obligations not yet due or which are being contested in good faith, (v) operators', vendors', suppliers of necessaries to Transocean's drilling units, carriers', warehousemen's, repairmen's, mechanics', workmen's, materialmen's, construction or shipyard liens (during repair or upgrade periods) or other like Liens arising by operation of law in the ordinary course of business or statutory landlord's liens, each of which is in respect of obligations that have not been outstanding more than 90 days (so long as no action has been taken to file or enforce such Liens within said 90-day period) or which are being contested in good faith and (vi) other Liens disclosed in the Transocean Disclosure Letter (the Liens described in clauses (i), (ii), (iii), (iv), (v) and (vi), collectively, "Transocean Permitted Liens"). No such asset is leased under an operating lease from a lessor that, to Transocean's knowledge, has incurred non-recourse indebtedness to finance the acquisition or construction of such asset.

        (b)   Except as would not have, individually or in the aggregate, a Transocean Material Adverse Effect, Transocean has caused the drilling units listed in Transocean's most recent annual report on 10-K to be maintained consistent with general practice in the offshore drilling industry, and all such drilling units are in good operating condition and repair consistent with general practice in the offshore drilling industry.

        Section 6.22    Undisclosed Liabilities.    Neither Transocean nor any of its Subsidiaries has any liabilities or obligations of any nature, whether or not fixed, accrued, contingent or otherwise, except liabilities and obligations that (i) are disclosed in the Transocean Reports filed prior to the date of this Agreement, (ii) are referred to in the Transocean Disclosure Letter, (iii) were incurred since March 31, 2007 in the ordinary course of business consistent with past practice or (iv) do not and are not reasonably likely to have, individually or in the aggregate, a Transocean Material Adverse Effect.

        (a)   Section 6.23 of the Transocean Disclosure Letter contains a list of all of the following contracts, commitments or agreements (other than those set forth on an exhibit index in the Transocean Reports filed prior to the date of this Agreement) to which Transocean or any Subsidiary of Transocean is a party or by which any of them or their assets is bound as of the date of this Agreement: (i) any non-competition agreement that purports to limit the manner in which, or the localities in which, all or any portion of their respective businesses is conducted other than any such limitation that is not material to Transocean and its Subsidiaries, taken as a whole, and will not be

A-36


material to Transocean and its Subsidiaries, taken as a whole, following the Effective Time, (ii) any drilling unit construction or conversion contract with respect to which the drilling unit has not been delivered and paid for, (iii) any drilling contracts of one year or greater remaining duration, including fixed price customer options, (iv) any contract or agreement for the borrowing of money with a borrowing capacity or outstanding indebtedness of $50 million or more, (v) any employment agreement between Transocean or any of its Subsidiaries, on the one hand, and any of Transocean's officers and key employees, on the other hand, (vi) any agreement which, upon the consummation of the Merger or any other transaction contemplated by this Agreement, will (either alone or upon the occurrence of any additional acts or events, including the passage of time) result in any payment or benefit (whether of severance pay or otherwise) becoming due, or the acceleration or vesting of any right to any payment or benefits, from Transocean or GlobalSantaFe or any of their respective Subsidiaries to any officer, director, consultant or employee of any of the foregoing, (vii) any agreement which is a material joint venture agreement, joint operating agreement, partnership agreement or other similar contract or agreement involving a sharing of profits and expenses with one or more third Persons, (viii) any agreement the benefits of which will be increased, or the vesting of the benefits of which will be accelerated, by the occurrence of any of the transactions contemplated by this Agreement, or the value of any of the benefits of which will be calculated on the basis of any of the transactions contemplated by this Agreement (including any stock option plan, stock appreciation rights plan, restricted stock plan or stock purchase plan) or (ix) any "material contract" (as such term is defined in Item 601(b)(10) of Regulation S-K of the SEC). Each contract, arrangement, commitment or understanding of the type described in this Section 6.23(a), whether or not included as an exhibit to any Transocean Report or included in Section 6.23 of the Transocean Disclosure Letter, is referred to herein as a "Transocean Material Contract," and for purposes of Section 7.1 and the bringdown of Section 6.23(b) pursuant to Section 8.2(a), "Transocean Material Contract" shall include any such contract, arrangement, commitment or understanding that is entered into after the date of this Agreement.

Except for such matters as do not and are not reasonably likely to have, individually or in the aggregate, a Transocean Material Adverse Effect, neither Transocean nor any of its Subsidiaries (x) knows of, or has received written notice of, any breach of or violation or default under (nor, to the knowledge of Transocean, does there exist any condition which with the passage of time or the giving of notice or both would result in such a violation or default under) any Transocean Material Contract or (y) has received written notice of the desire of the other party or parties to any such Transocean Material Contract to exercise any rights such party has to cancel, terminate or repudiate such contract or exercise remedies thereunder. Except as would not be reasonably likely to have, individually or in the aggregate, a Transocean Material Adverse Effect, the consummation of the transactions contemplated by this Agreement will not breach or violate any Transocean Material Contract or permit any other party to a Transocean Material Contract to exercise rights adverse to Transocean. Each Transocean Material Contract is enforceable by Transocean or a Subsidiary of Transocean in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to creditors' rights and general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity), except where such unenforceability is not reasonably likely to create, individually or in the aggregate, a Transocean Material Adverse Effect.

        Section 6.24    Capital Expenditure Program.    As of the date of this Agreement, the Transocean Disclosure Letter accurately sets forth in all material respects, for each of Transocean's sustaining, life extension and newbuild capital expenditure programs, the capital expenditures for all such programs

A-37

All such Derivative Transactions were, and any Derivative Transactions entered into after the date of this Agreement will be, entered into in accordance with Applicable Laws, and in accordance with the investment, securities, commodities, risk management and other policies, practices and procedures employed by Transocean and its Subsidiaries, and were, and will be, entered into with counterparties believed at the time, and except as set forth in Section 6.25 of the Transocean Disclosure Letter, still believes to be financially responsible and able to understand (either alone or in consultation with their advisers) and to bear the risks of such Derivative Transactions. Transocean and each of its Subsidiaries have, and will have, duly performed all of their respective obligations under the Derivative Transactions to the extent that such obligations to perform have accrued, and, to the knowledge of Transocean, there are and will be no breaches, violations, collateral deficiencies, requests for collateral or demands for payment, or defaults or allegations or assertions of such by any party thereunder.

        Section 6.26    Disclosure Controls and Procedures.    Transocean has established and maintains "disclosure controls and procedures" (as defined in Rules 13a-14(c) and 15d-14(c) of the Exchange Act) that are reasonably designed to ensure that all material information (both financial and non-financial) required to be disclosed by Transocean in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that all such information is accumulated and communicated to Transocean's management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the Chief Executive Officer and Chief Financial Officer of Transocean required under the Exchange Act with respect to such reports. Except as set forth in Transocean's Annual Report on Form 10-K for the fiscal year ended December 31, 2006, since January 1, 2006, neither Transocean nor its independent auditors have identified any "significant deficiencies" or "material weaknesses" in Transocean's or any of its Subsidiaries' internal controls as contemplated under Section 404 of the Sarbanes-Oxley Act.

        Section 6.27    Affiliate Transactions.    There are no material agreements, contracts, transfers of assets or liabilities or other commitments or transactions (other than Transocean Benefit Plans described in Section 6.11 of the Transocean Disclosure Letter), whether or not entered into in the ordinary course of business, to or by which Transocean or any of its Subsidiaries, on the one hand, and any of their respective Affiliates (other than Transocean or any of its direct or indirect wholly owned Subsidiaries) on the other hand, are or have been a party or otherwise bound or affected, and that (a) are currently pending, in effect or have been in effect at any time since December 31, 2005 or (b) involve continuing liabilities and obligations that, individually or in the aggregate, have been, are or will be material to Transocean and its Subsidiaries taken as a whole.

generality of the foregoing, neither Transocean nor Merger Sub nor any other Person will have or be subject to any liability or indemnification obligation to GlobalSantaFe or any other Person resulting from the distribution to GlobalSantaFe, or use by GlobalSantaFe of, any such information, including any information, documents, projections, forecasts or other material made available to GlobalSantaFe in certain "data rooms" or management presentations in expectation of the transactions contemplated by this Agreement.

        (b)   In connection with investigation by GlobalSantaFe of Transocean and its Subsidiaries, GlobalSantaFe has received or may receive from Transocean and/or Transocean's Subsidiaries certain projections, forward-looking statements and other forecasts and certain business plan information. GlobalSantaFe acknowledges that there are uncertainties inherent in attempting to make such estimates, projections and other forecasts and plans, that GlobalSantaFe is familiar with such uncertainties, that GlobalSantaFe is taking full responsibility for making its own evaluation of the adequacy and accuracy of all estimates, projections and other forecasts and plans so furnished to it (including the reasonableness of the assumptions underlying such estimates, projections, forecasts or plans), and that, absent fraud or willful misrepresentation, GlobalSantaFe shall have no claim against anyone with respect thereto. Accordingly, GlobalSantaFe acknowledges that Transocean makes no representation or warranty with respect to such estimates, projections, forecasts or plans (including the reasonableness of the assumptions underlying such estimates, projections, forecasts or plans).

        (a)   GlobalSantaFe agrees that (i) neither it nor any of its Subsidiaries shall, and it shall not authorize or permit any of its officers, directors, employees, agents or representatives (including any investment banker, attorney or accountant retained by it or any of its Subsidiaries) (the "GlobalSantaFe Representatives") to, and on becoming aware of it will use its reasonable best efforts to stop such GlobalSantaFe Representative from continuing to, directly or indirectly, solicit, initiate or knowingly encourage (including by way of furnishing nonpublic information), or take any action designed to approve, endorse, recommend, or facilitate, directly or indirectly, any inquiry, proposal or offer (including any proposal or offer to its shareholders) with respect to a tender or exchange offer, scheme of arrangement, merger, consolidation, business combination, purchase or similar transaction or series of transactions (other than the transactions contemplated by this Agreement) involving, individually or

A-42


in the aggregate, 15% or more of the assets, net revenues or net income of GlobalSantaFe and its Subsidiaries on a consolidated basis or 15% or more of any class of share capital of GlobalSantaFe, including any scheme of arrangement, merger, consolidation, business combination, purchase or similar transaction in which 15% or more of GlobalSantaFe's share capital is issued to a third party or its shareholders (any such inquiry, proposal or offer being hereinafter referred to as a "GlobalSantaFe Acquisition Proposal"), or cooperate with or assist, participate or engage in any substantive discussions or negotiations concerning a GlobalSantaFe Acquisition Proposal, or amend, terminate, waive or fail to enforce, or grant any consent under, any confidentiality, standstill or similar agreement, or resolve to propose or agree to do any of the foregoing; and (ii) it will immediately cease and cause to be terminated any existing negotiations with any parties conducted heretofore with respect to any of the foregoing; provided that (1) nothing contained in this Agreement shall prevent GlobalSantaFe or its Board of Directors from (A) complying with Rule 14e-2 promulgated under the Exchange Act with regard to a GlobalSantaFe Acquisition Proposal, (B) prior to the Cutoff Date (as defined herein), providing information (pursuant to a confidentiality and standstill agreement in reasonably customary form with terms at least as favorable to GlobalSantaFe as the Confidentiality and Standstill Agreement dated June 26, 2007, between Transocean and GlobalSantaFe (the "Confidentiality and Standstill Agreement") and which does not contain terms that prevent GlobalSantaFe from complying with its obligations under this Section 7.2) to or engaging in any negotiations or substantive discussions with any Person who has made an unsolicited bona fide written GlobalSantaFe Acquisition Proposal that the Board of Directors of GlobalSantaFe determines in good faith constitutes a GlobalSantaFe Superior Proposal (as defined herein), to the extent the Board of Directors of GlobalSantaFe, after consultation with its outside legal counsel, determines that the failure to do so would be inconsistent with its fiduciary obligations, or (C) prior to the Cutoff Date, taking any action permitted pursuant to Section 7.1(s) hereof and (2) notwithstanding anything in this Agreement to the contrary, the Board of Directors of GlobalSantaFe or any committee thereof may make a GlobalSantaFe Adverse Recommendation Change (as defined herein) in accordance with Section 7.4(d). For the purposes of making a GlobalSantaFe Superior Proposal determination pursuant to this Section 7.2(a), it is understood that such determination necessarily will (i) be based on limited information compared to the determination made for purposes of Section 9.3(c), (ii) require assumptions that shall be made in the good faith judgment of the GlobalSantaFe Board of Directors and (iii) not be as complete or informed as, and will be distinct from, a GlobalSantaFe Superior Proposal determination made for purposes of Section 9.3(c). For the avoidance of doubt, it is understood that a GlobalSantaFe Superior Proposal determination made for purposes of Section 7.2(a) shall not constitute a GlobalSantaFe Superior Proposal determination for any other purpose under this Agreement (except for Section 9.5(a)(i)(A)(1)(a) of this Agreement) and shall not by itself constitute a GlobalSantaFe Adverse Recommendation Change for purposes of this Agreement. Without limiting the foregoing, it is understood that any violation of this Section 7.2 by any Subsidiary of GlobalSantaFe or the GlobalSantaFe Representatives shall be deemed to be a breach of this Section 7.2 by GlobalSantaFe.

        (b)   As promptly as practicable after receipt thereof (and in any event within 24 hours), and prior to participating in any substantive discussions or negotiations, GlobalSantaFe will notify Transocean orally and in writing of any request for information from any Person that has made a GlobalSantaFe Acquisition Proposal (or has indicated to GlobalSantaFe that it is seeking such information in contemplation of making a GlobalSantaFe Acquisition Proposal) or the receipt of any GlobalSantaFe Acquisition Proposal or any inquiry with respect to a GlobalSantaFe Acquisition Proposal, including the identity of the Person or group engaging in such substantive discussions or negotiations, requesting such information or making such GlobalSantaFe Acquisition Proposal, and the material terms and conditions of any GlobalSantaFe Acquisition Proposal. GlobalSantaFe will (i) keep Transocean reasonably informed on a timely basis (and in any event within 24 hours) of the status and material details of any GlobalSantaFe Acquisition Proposals, (ii) provide to Transocean as soon as practicable (and in any event within 24 hours) after receipt or delivery thereof with copies of all correspondence and other

A-43



written material sent or provided to GlobalSantaFe from any third party in connection with any GlobalSantaFe Acquisition Proposal or sent or provided by GlobalSantaFe to any third party in connection with any GlobalSantaFe Acquisition Proposal and (iii) provide or make available to Transocean any material nonpublic information concerning GlobalSantaFe or any of its Subsidiaries that is provided to the Person making such GlobalSantaFe Acquisition Proposal which was not previously provided or made available to Transocean as promptly as practicable (and in any event within 24 hours) after it provides such information to such Person. Any written notice under this Section 7.2 shall be given by facsimile with receipt confirmed or personal delivery. Notwithstanding anything in this Agreement to the contrary, no failure by GlobalSantaFe to comply with any notice or delivery requirement set forth in this Section 7.2 shall constitute a breach of this Section 7.2 unless such failure is intentional or materially prejudicial to Transocean.

        (c)   Without limiting the ability to take action pursuant to Section 7.1(s), nothing in this Section 7.2 shall permit GlobalSantaFe to enter into any agreement with respect to a GlobalSantaFe Acquisition Proposal during the term of this Agreement, it being agreed that during the term of this Agreement (except pursuant to Section 9.3(c)), GlobalSantaFe shall not enter into any agreement with any Person that provides for, constitutes or relates to, a GlobalSantaFe Acquisition Proposal, other than a confidentiality and standstill agreement in reasonably customary form with terms at least as favorable to GlobalSantaFe as the Confidentiality and Standstill Agreement and which does not contain terms that prevent GlobalSantaFe from complying with its obligations under this Section 7.2 and an executed copy of which shall be promptly (and in any event within 24 hours) provided to Transocean.

        (d)   For purposes hereof:

        Section 7.3    No Solicitation by Transocean.    

        (a)   Transocean agrees that (i) neither it nor any of its Subsidiaries shall, and it shall not authorize or permit any of its officers, directors, employees, agents or representatives (including any investment banker, attorney or accountant retained by it or any of its Subsidiaries) (the "Transocean Representatives") to, and on becoming aware of it will use its reasonable best efforts to stop such Transocean Representative from continuing to, directly or indirectly, solicit, initiate or knowingly encourage (including by way of furnishing nonpublic information), or take any action designed to approve, endorse, recommend, or facilitate, directly or indirectly, any inquiry, proposal or offer (including any proposal or offer to its shareholders) with respect to a tender or exchange offer, scheme of arrangement, merger, consolidation, business combination, purchase or similar transaction or series of transactions (other than the transactions contemplated by this Agreement) involving, individually or

A-44


in the aggregate, 15% or more of the assets, net revenues or net income of Transocean and its Subsidiaries on a consolidated basis or 15% or more of any class of share capital of Transocean including any scheme of arrangement, merger, consolidation, business combination, purchase or similar transaction in which 15% or more of Transocean's share capital is issued to a third party or its shareholders (any such inquiry, proposal or offer being hereinafter referred to as a "Transocean Acquisition Proposal") or cooperate with or assist, participate or engage in any substantive discussions or negotiations concerning a Transocean Acquisition Proposal or amend, terminate, waive or fail to enforce, or grant any consent under, any confidentiality, standstill or similar agreement, or resolve to propose or agree to do any of the foregoing; and (ii) it will immediately cease and cause to be terminated any existing negotiations with any parties conducted heretofore with respect to any of the foregoing; provided that (1) nothing contained in this Agreement shall prevent Transocean or its Board of Directors from (A) complying with Rule 14e-2 promulgated under the Exchange Act with regard to a Transocean Acquisition Proposal, (B) prior to the Cutoff Date (as defined herein), providing information (pursuant to a confidentiality and standstill agreement in reasonably customary form with terms at least as favorable to Transocean as the Confidentiality and Standstill Agreement and which does not contain terms that prevent Transocean from complying with its obligations under this Section 7.3) to or engaging in any negotiations or substantive discussions with any Person who has made an unsolicited bona fide written Transocean Acquisition Proposal that the Board of Directors of Transocean determines in good faith constitutes a Transocean Superior Proposal (as defined herein), to the extent the Board of Directors of Transocean, after consultation with its outside legal counsel, determines that the failure to do so would be inconsistent with its fiduciary obligations, or (C) prior to the Cutoff Date, taking any action permitted pursuant to Section 7.1(s) hereof and (2) notwithstanding anything in this Agreement to the contrary, the Board of Directors of Transocean or any committee thereof may make a Transocean Adverse Recommendation Change (as defined herein) in accordance with Section 7.4(c). For the purposes of making a Transocean Superior Proposal determination pursuant to this Section 7.3(a), it is understood that such determination necessarily will (i) be based on limited information compared to the determination made for purposes of Section 9.4(c), (ii) require assumptions that shall be made in the good faith judgment of the Transocean Board of Directors and (iii) not be as complete or informed as, and will be distinct from, a Transocean Superior Proposal determination made for purposes of Section 9.4(c). For the avoidance of doubt, it is understood that a Transocean Superior Proposal determination made for purposes of Section 7.3(a) shall not constitute a Transocean Superior Proposal determination for any other purpose under this Agreement (except for Section 9.5(b)(i)(A)(1)(a) of this Agreement) and shall not by itself constitute a Transocean Adverse Recommendation Change for purposes of this Agreement. Without limiting the foregoing, it is understood that any violation of this Section 7.3 by any Subsidiary of Transocean or the Transocean Representatives shall be deemed to be a breach of this Section 7.3 by Transocean.

        (b)   As promptly as practicable after receipt thereof (and in any event within 24 hours), and prior to participating in any substantive discussions or negotiations, Transocean will notify GlobalSantaFe orally and in writing of any request for information from any Person that has made a Transocean Acquisition Proposal (or has indicated to Transocean that it is seeking such information in contemplation of making a Transocean Acquisition Proposal) or the receipt of any Transocean Acquisition Proposal or any inquiry with respect to a Transocean Acquisition Proposal, including the identity of the Person or group engaging in such substantive discussions or negotiations, requesting such information or making such Transocean Acquisition Proposal, and the material terms and conditions of any Transocean Acquisition Proposal. Transocean will (i) keep GlobalSantaFe reasonably informed on a timely basis (and in any event within 24 hours) of the status and material details of any Transocean Acquisition Proposals, (ii) provide to GlobalSantaFe as soon as practicable (and in any event within 24 hours) after receipt or delivery thereof with copies of all correspondence and other written material sent or provided to Transocean from any third party in connection with any Transocean Acquisition Proposal or sent or provided by Transocean to any third party in connection with any Transocean

A-45


Acquisition Proposal and (iii) provide or make available to GlobalSantaFe any material nonpublic information concerning Transocean or any of its Subsidiaries that is provided to the Person making such Transocean Acquisition Proposal which was not previously provided or made available to GlobalSantaFe as promptly as practicable (and in any event within 24 hours) after it provides such information to such Person. Any written notice under this Section 7.3 shall be given by facsimile with receipt confirmed or personal delivery. Notwithstanding anything in this Agreement to the contrary, no failure by Transocean to comply with any notice or delivery requirement set forth in this Section 7.3 shall constitute a breach of this Section 7.3 unless such failure is intentional or materially prejudicial to GlobalSantaFe.

        (c)   Without limiting the ability to take action pursuant to Section 7.1(s), nothing in this Section 7.3 shall permit Transocean to enter into any agreement with respect to a Transocean Acquisition Proposal during the term of this Agreement, it being agreed that during the term of this Agreement (except pursuant to Section 9.4(c)), Transocean shall not enter into any agreement with any Person that provides for, constitutes or relates to, a Transocean Acquisition Proposal, other than a confidentiality and standstill agreement in reasonably customary form with terms at least as favorable to Transocean as the Confidentiality and Standstill Agreement and which does not contain terms that prevent Transocean from complying with its obligations under this Section and an executed copy of which shall be promptly (and in any event within 24 hours) provided to GlobalSantaFe.

        (d)   For purposes hereof:

        Section 7.4    Meetings of Shareholders to Consider the Merger and Reclassification by Way of Schemes of Arrangement.    

        (a)   Notwithstanding any other provision of this Agreement, unless this Agreement is terminated in accordance with the terms hereof, Transocean shall submit (i) the Reclassification and the issuance of Transocean Ordinary Shares in the Merger and (ii) the Amended and Restated Transocean Memorandum and the Amended and Restated Transocean Articles, to its shareholders in accordance with the provisions of Section 7.15, whether or not the Board of Directors of Transocean or GlobalSantaFe, as the case may be, withdraws, modifies or changes its recommendation and declaration regarding the foregoing matters.

        (b)   Notwithstanding any other provision of this Agreement, unless this Agreement is terminated in accordance with the terms hereof, GlobalSantaFe shall submit the Merger to its shareholders in accordance with the provisions of Section 7.15, whether or not the Board of Directors of

A-46



GlobalSantaFe withdraws, modifies or changes its recommendation and declaration regarding the foregoing matter.

        (c)   Transocean, through its Board of Directors, shall recommend approval of the Reclassification and the issuance of Transocean Ordinary Shares in the Merger, and use its reasonable best efforts to solicit from its shareholders proxies in favor of such matters; provided, however, that the Board of Directors of Transocean may at any time prior to the Cutoff Date upon one business day's prior written notice to GlobalSantaFe, make a Transocean Adverse Recommendation Change, if in the good faith opinion of such Board of Directors after consultation with its outside legal counsel the failure to do so would be inconsistent with its fiduciary obligations.

        (d)   GlobalSantaFe, through its Board of Directors, shall recommend approval of the Merger, and use its reasonable best efforts to solicit from its shareholders proxies in favor of such matter; provided, however, that the Board of Directors of GlobalSantaFe may at any time prior to the Cutoff Date upon one business day's prior written notice to Transocean, make a GlobalSantaFe Adverse Recommendation Change, if in the good faith opinion of such Board of Directors after consultation with its outside legal counsel the failure to do so would be inconsistent with its fiduciary obligations.

        (e)   Transocean shall take all action necessary to cause Merger Sub to approve the Merger as the sole shareholder of Merger Sub prior to the Closing.

        Section 7.5    Filings; Reasonable Best Efforts, Etc.

A-47


        (b)   Without limiting Section 7.5(a), but subject to Sections 7.5(c) and 7.5(d), Transocean and GlobalSantaFe shall:

        (c)   Nothing in this Agreement shall require Transocean or GlobalSantaFe to take any Competition Action to obtain any consents, approvals, permits or authorizations or to remove any impediments to the Merger relating to the HSR Act, Non-U.S. Antitrust Laws, or other antitrust, competition or premerger notification trade regulation law, regulation or order ("Antitrust Laws") or to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order in any suit or proceedings relating to Antitrust Laws. For purposes of this Agreement, "Competition Action" means, with respect to Transocean or GlobalSantaFe, to dispose of any of its assets or to limit its freedom of action with respect to any of its businesses, or to consent to any disposition of its assets or limits on its freedom of action with respect to any of its businesses, whether prior to or after the Effective Time, or to commit or agree to any of the foregoing, in each case other than dispositions, limitations or consents, commitments or agreements which in each such case may be conditioned upon the consummation of the Merger and the transactions contemplated hereby and which, in the reasonable good faith judgment of both Transocean and GlobalSantaFe, in each such case do not and are not reasonably likely to individually or in the aggregate either (i) have a Transocean Material Adverse Effect; (ii) have a GlobalSantaFe Material Adverse Effect; (iii) materially impair the benefits or advantages which it expects to receive from the Merger and the transactions contemplated hereby or (iv) have a material adverse effect on the business plan or business strategy for the combined company. Notwithstanding anything contained in this Agreement to the contrary, neither Transocean nor GlobalSantaFe shall take or agree to take any Competition Action without the prior written agreement of the other.

A-48



representation or warranty given by any party hereunder, and provided further that notwithstanding the provision of information or investigation by any party, no party shall be deemed to make any representation or warranty except as expressly set forth in this Agreement. Notwithstanding the foregoing, no party shall be required to provide any information which it reasonably believes it may not provide to the other party by reason of Applicable Law, which constitutes information protected by attorney/client privilege, or which it is required to keep confidential by reason of contract or agreement with third parties. The parties hereto shall make reasonable and appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. Each of Transocean and GlobalSantaFe agrees that it shall not, and shall cause its respective representatives not to, use any information obtained pursuant to this Section 7.6 for any purpose unrelated to the consummation of the transactions contemplated by this Agreement.

The respective parties will cause the Proxy Statement/Prospectus and the Form S-4 to comply as to form in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the rules and regulations thereunder.

        Section 7.13    Indemnification and Insurance.    

        (a)   From and after the Effective Time, Transocean and the Surviving Entity shall indemnify, defend and hold harmless to the fullest extent permitted under Applicable Law each Person who is, or has been at any time prior to the Effective Time, an executive officer or director of Transocean or GlobalSantaFe (or any Subsidiary or division thereof) and each Person who served at the request of Transocean or GlobalSantaFe as a director, officer, trustee or fiduciary of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise (individually, an "Indemnified Party" and, collectively, the "Indemnified Parties") against all losses, claims, damages, liabilities, costs or expenses (including attorneys' fees), judgments, fines, penalties and amounts paid in settlement in connection with any claim, action, suit, proceeding or investigation arising out of or pertaining to acts or omissions, or alleged acts or omissions, by them in their capacities as such, whether commenced, asserted or claimed before or after the Effective Time. In the event of any such claim, action, suit, proceeding or investigation (an "Action"), (i) Transocean and the Surviving Entity shall pay, as incurred, the fees and expenses of counsel selected by the Indemnified Party, which counsel shall be reasonably acceptable to Transocean and the Surviving Entity, in advance of the final disposition of any such Action to the fullest extent permitted by Applicable Law and, if required, upon receipt of any undertaking required by Applicable Law, and (ii) Transocean and the Surviving Entity will cooperate in the defense of any such matter; provided, however, Transocean and the Surviving Entity shall not be liable for any settlement effected without its written consent (which consent shall not be unreasonably withheld or delayed), and provided further, that Transocean and the Surviving Entity shall not be obligated pursuant to this Section 7.13 to pay the fees and disbursements of more than one counsel for all Indemnified Parties in any single Action, unless, in the good faith judgment of any of the Indemnified Parties, there is or may be a conflict of interests between two or more of such Indemnified Parties, in which case there may be separate counsel for each similarly situated group.

        (b)   Each of the parties agrees that the rights to indemnification, including provisions relating to advances of expenses incurred in defense of any action or suit, in its memorandum of association and articles of association with respect to matters occurring through the Effective Time, shall survive the Merger.

        (c)   For a period of six years after the Effective Time, Transocean and the Surviving Entity shall cause to be maintained officers' and directors' liability insurance covering the Indemnified Parties who are, or at any time prior to the Effective Time were, covered by Transocean and GlobalSantaFe's existing officers' and directors' liability insurance policies on terms substantially no less advantageous to the Indemnified Parties than such existing insurance, provided that Transocean and the Surviving Entity shall not be required to pay annual premiums in excess of 250% of the last annual premium paid by Transocean prior to the date hereof (the amount of which premium is set forth in the Transocean Disclosure Letter), but in such case shall purchase as much coverage as reasonably practicable for such amount (but in no event shall Transocean or the Surviving Entity be required to purchase coverage in an amount in excess of the coverage currently maintained by Transocean).

        (d)   The rights of each Indemnified Party hereunder shall be in addition to any other rights such Indemnified Party may have under the memorandum of association, articles of association or comparable organizational documents of Transocean or any of its Subsidiaries or GlobalSantaFe or any of its Subsidiaries, as applicable, under Applicable Law or otherwise. The provisions of this

A-51



Section 7.13 shall survive the consummation of the Merger and expressly are intended to benefit each of the Indemnified Parties.

        (e)   In the event Transocean, the Surviving Entity or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then and in either such case, proper provision shall be made so that the successors and assigns of Transocean or the Surviving Entity, as the case may be, shall assume the obligations set forth in this Section 7.13.

        Section 7.14    Employee Matters.    

        (a)   At the Effective Time, Transocean and its Subsidiaries will continue the employment of all of the employees who are employed by Transocean, GlobalSantaFe or any of their Subsidiaries as of the day immediately prior to the Effective Time (the "Affected Employees") initially at the same salaries and wages of such employees immediately prior to the Effective Time. During the period from the Effective Time to and including December 31, 2008, Transocean and its Subsidiaries (i) shall provide each Affected Employee with an annual salary rate or hourly wage rate, as applicable, that is no less favorable to such Affected Employee than the salary rate or wage rate provided to such Affected Employee immediately prior to the Effective Time, and (ii) shall provide Affected Employees who are so employed by GlobalSantaFe or its Subsidiaries as of the day immediately prior to the Effective Time, in the aggregate, with employee compensation and benefits no less favorable in the aggregate than those provided by GlobalSantaFe or its Subsidiaries immediately prior to the Effective Time. Nothing in this Agreement shall be considered a contract between Transocean and its Subsidiaries and any Affected Employee or consideration for, or inducement with respect to, any such employee's continued employment and, without limitation, all such employees are and will continue to be considered to be employees at will pursuant to the applicable employment at will laws or doctrines, subject to any express written agreement to the contrary with such employee. From and after the Effective Time, Transocean shall honor, and shall cause Transocean Offshore Deepwater Drilling Inc. ("TODDI") to honor each severance agreement listed in Section 7.14(a) of the GlobalSantaFe Disclosure Letter and to perform the obligations of GlobalSantaFe thereunder and, prior to the Effective Time, Transocean shall, and shall cause TODDI to, enter into a novation agreement in the form of Exhibit 7.14 with respect thereto, which novation agreement shall become effective immediately prior to the Effective Time.

        (b)   With respect to each Affected Employee, Transocean shall credit, or cause its Subsidiaries to credit, the period of employment and service recognized by the applicable employer immediately prior to the Effective Time (for purposes of its corresponding plans, programs, policies or similar employment-related arrangements) to have been employment and service with Transocean for purposes of determining the Affected Employee's eligibility to join (subject to satisfaction of all non-service related eligibility criteria) and vesting (but not benefit accrual for any purpose other than vacation pay, severance and termination pay, sick leave, post-retirement health coverage and satisfaction of early retirement criteria) under all employee benefit plans, programs, policies or similar employment related arrangements of Transocean and its Subsidiaries in which the Affected Employee is eligible to participate; provided, however, no such credit shall be provided to the extent that it would result in a duplication of credit or benefits. Transocean shall waive, and to the extent necessary to effect the terms hereof, shall use its best efforts to cause the relevant insurance carriers and other third parties to waive, any restrictions and limitations for medical conditions existing as of the Effective Time of those Affected Employees and their dependents who were covered immediately prior to the Effective Time under a group health plan maintained by Transocean or GlobalSantaFe, but only to the extent that such medical condition would be covered by Transocean's group health plan if it were not a pre-existing condition and only to the extent that such limitations would not have applied under Transocean or GlobalSantaFe's group health plan prior to the Effective Time. Further, Transocean shall offer, or

A-52



cause its Subsidiaries to offer, at the Effective Time to each Affected Employee coverage under a group health plan (as defined in Section 5000(b)(1) of the Code) which credits such Affected Employee towards the deductibles, coinsurance and maximum out-of-pocket provisions imposed under such group health plan, for the year during which the Effective Time (or such later date as the Affected Employees participate in such group health plan) occurs, with any applicable expenses already incurred during such year under Transocean or GlobalSantaFe's group health plan.

        (c)   Transocean and GlobalSantaFe agree that Transocean shall establish a severance plan, the general terms of which have been agreed upon and are set forth in Section 7.14 of the Transocean Disclosure Letter, effective for no less than the period from the Effective Time until the second anniversary of the Effective Time, for the benefit of Affected Employees on a U.S. dollar payroll who are eligible to participate pursuant to the terms as so set forth. Transocean and GlobalSantaFe agree to cooperate in good faith to take appropriate and substantially consistent actions to retain key employees and provide for a smooth transition, including such action as they deem appropriate to provide for retention payments under substantially consistent terms following the Closing Date.

        (d)   Transocean and GlobalSantaFe agree to cooperate in good faith to establish a process to promptly integrate the Transocean Benefit Plans and the GlobalSantaFe Benefit Plans following the Effective Time.

        (e)   Transocean shall pay, or shall cause its Subsidiaries to pay, to each Affected Employee who was employed by Transocean or its Subsidiaries immediately prior to the Effective Time an amount, to the extent then unpaid, equal to the annual incentive bonus to which the Affected Employee would be entitled under the terms of Transocean's 2007 Performance Award and Cash Bonus Plan and applicable award letters. On March 14, 2008, Transocean shall pay, or shall cause its Subsidiaries to pay, to each Affected Employee who was employed by GlobalSantaFe or its Subsidiaries immediately prior to the Effective Time (or if the Effective Time shall have not yet occurred, GlobalSantaFe shall pay, or shall cause its Subsidiaries to pay, to each person who is an employee of GlobalSantaFe or its Subsidiaries on March 14, 2008) amounts equal to (i) any annual incentive bonus to which GlobalSantaFe determined (prior to the Effective Time) the Affected Employee (or employee, as the case may be) would be entitled under GlobalSantaFe's 2007 non-equity annual incentive plan(s) and (ii) any amount to which GlobalSantaFe determined (prior to the Effective Time) that the Affected Employee (or employee, as the case may be) would be entitled with respect to GlobalSantaFe's outstanding cash-based performance units. If the employment of an Affected Employee who would otherwise be entitled to a payment under clause (i) and/or clause (ii) of the immediately preceding sentence is involuntarily terminated, or such an Affected Employee voluntarily terminates employment after attaining age 55 and five years of service, prior to March 14, 2008, the payment or payments shall nevertheless be made to such Affected Employee on March 14, 2008. In the event the Effective Time occurs in 2008, immediately prior to the Effective Time, (i) Transocean shall have the right to pay each Affected Employee who was eligible to receive an annual incentive bonus under the Transocean Performance Award and Cash Bonus Plan in effect at such time (the "Transocean 2008 Annual Incentive Plan"), a cash bonus for the period from January 1, 2008 through the Effective Time equal to a pro rata portion of the total maximum bonus payable for 2008 under the Transocean 2008 Annual Incentive Plan, which shall not exceed the maximum target payout percentage established for 2007, provided that the CFROMC factor used for this purpose will not exceed 1.0, and (ii) GlobalSantaFe shall have the right to pay each Affected Employee who was eligible to receive an annual incentive bonus under GlobalSantaFe's 2007 non-equity annual incentive plan(s) a cash bonus for the period from January 1, 2008 through the Effective Time which shall not exceed a pro rata portion of the total bonus paid or payable to the Affected Employee under the applicable 2007 plan, in each case determined on the basis of the number of days elapsed from January 1, 2008 through the Effective Time, with such payments to be in lieu of the portion of the annual bonus that would otherwise be paid with respect to such period. The Board of Directors of Transocean, or any committee designated

A-53



by the Board of Directors, shall establish performance goals and cash bonus targets for the period following the Effective Time in its discretion.

        (f)    All Transocean cash-settled stock appreciation rights (individually, a "Transocean Cash SAR" and collectively, the "Transocean Cash SARs") outstanding at the Initial Effective Time under the Transocean Stock Plans shall remain outstanding following the Initial Effective Time, except that immediately following the Initial Effective Time (A) each Transocean Cash SAR shall be exercisable with respect to that whole number of Transocean Ordinary Shares equal to the product (rounded down to the nearest whole share) of the number of Transocean Ordinary Shares to which the Transocean Cash SAR related immediately prior to the Initial Effective Time multiplied by the Transocean Adjustment Fraction, and (B) the exercise price per Transocean Ordinary Share shall be an amount equal to the exercise price per Transocean Ordinary Share in effect immediately prior to the Initial Effective Time divided by the Transocean Adjustment Fraction (the price per share, as so determined, being rounded up to the nearest whole cent) and, as adjusted, each Transocean Cash SAR shall remain exercisable in accordance with its terms.

        (g)   Except with respect to offers of employment to prospective new employees in the ordinary course of business consistent with past practices, Transocean and GlobalSantaFe agree that they shall not make, and shall cause their respective Subsidiaries not to make, any representations or promises, oral or written, to any of their employees concerning continued employment following the Effective Time, or the terms and conditions of that employment, except in writing with the prior written consent of the other party.

        (h)   Notwithstanding the foregoing, nothing in this Agreement, whether express or implied, shall be treated as an amendment or other modification of any Transocean Benefit Plan, GlobalSantaFe Benefit Plan or compensation or benefit plan, program or arrangement of Transocean or its Subsidiaries, or shall limit the right of Transocean, GlobalSantaFe or any of their Subsidiaries, to amend, terminate or otherwise modify any such plan or arrangement. In the event that (i) a party other than Transocean, GlobalSantaFe or any of their Subsidiaries makes a claim or takes other action to enforce any provision in this Agreement as an amendment to any such plan or arrangement, and (ii) such provision is deemed to be an amendment to such plan or arrangement even though not explicitly designated as such in this Agreement, then such provision shall lapse retroactively and shall have no amendatory effect.

        (i)    For the avoidance of doubt, Transocean deems that the Merger, the Reclassification and the transactions contemplated by this Agreement constitute a change of control of Transocean with respect to (i) the Transocean Executive Change of Control Severance Benefit, (ii) the Long-Term Incentive Plan of Transocean, (iii) the Deferred Compensation Plan of Transocean, (iv) the Performance Award and Cash Bonus Plan of Transocean and (v) any awards under the Transocean Stock Plans, except for the awards specified on Section 7.14 of the Transocean Disclosure Letter.

        Section 7.15    Schemes of Arrangement.    

        (a)   As soon as practicable after the date hereof and in accordance with this Agreement, Transocean will (i) issue a petition seeking the sanction of the Reclassification and cause application to be made to the Grand Court of the Cayman Islands (the "Court") requesting the Court to summon such meetings of the holders of the ordinary shares of Transocean as the Court may direct, (ii) convene such meetings to obtain the approvals required under Section 86(2) of the Companies Law and, subject to such approvals being obtained, (iii) following the obtaining of the approval required under Section 86(2) of the Companies Law, issue a summons before the Court seeking the sanction of the Reclassification pursuant to Section 86 of the Companies Law and file such other documents as are required to be duly filed with the Court to effect the Reclassification. Transocean shall undertake to the Court that it shall issue and pay, subject to the provisions of this Agreement, at the Initial Effective Time, the Transocean Reclassification Consideration and, at the Effective Time, the GlobalSantaFe

A-54


Merger Consideration. As soon as practicable following the satisfaction or waiver (subject to Applicable Laws) of the conditions set forth in this Agreement, at the Closing, Transocean shall cause the order of the Court sanctioning the Reclassification pursuant to Section 86 of the Companies Law and making such facilitating order as is appropriate pursuant to Section 87(2) of the Companies Law (the "Transocean Court Order") to be filed with the Registrar of Companies of the Cayman Islands. The Reclassification shall become effective at the time of filing of the Transocean Court Order (the "Initial Effective Time").

        (b)   As soon as practicable after the date hereof and in accordance with this Agreement, GlobalSantaFe will (i) issue a petition seeking the sanction of the Merger and cause an application to be made to the Court requesting the Court to summon such meetings of the holders of the ordinary shares of GlobalSantaFe as the Court may direct, (ii) convene such meetings to obtain the approval required under Section 86(2) of the Companies Law and, subject to such approval being obtained, (iii) following the obtaining of the approval required under Section 86(2) of the Companies Law, seeking the sanction of the Merger pursuant to Section 86 of the Companies Law on the hearing of the petition and file such other documents as are required to be duly filed with the Court to effect the Merger. As soon as practicable after the date of this Agreement and in accordance with this Agreement, Merger Sub will take, and Transocean will cause Merger Sub to take, any and all actions necessary to effect the Merger. Transocean shall undertake to the Court that, at the Effective Time, it shall issue and pay, subject to the provisions of this Agreement, the GlobalSantaFe Merger Consideration. As soon as practicable following the satisfaction or waiver (subject to Applicable Laws) of the conditions set forth in this Agreement, at the Closing, GlobalSantaFe and Merger Sub shall cause the orders of the Court sanctioning the Merger pursuant to Section 86 of the Companies Law and making such facilitating orders as are appropriate pursuant to Section 87(2) of the Companies Law (the "GlobalSantaFe Court Orders") to be filed with the Registrar of Companies of the Cayman Islands. The Merger shall become effective at the later of the time of the filing of the GlobalSantaFe Court Orders and one minute following the Initial Effective Time (the "Effective Time").

        Section 7.16    Financing.    

        (a)   Section 7.16 of the Transocean Disclosure Letter sets forth copies of an executed debt commitment letter, related term sheet and related fee letter (collectively, the "Financing Commitments") pursuant to which, and subject to the terms and conditions thereof, certain lenders have committed to provide Transocean with loans in the amounts described therein, the proceeds of which may be used to consummate the Merger and the Reclassification and the other transactions contemplated hereby (the "Financing"). To the knowledge of each party, no event has occurred which, with or without notice, lapse of time or both, could reasonably be expected to constitute a material breach by any party hereto or failure to satisfy a condition precedent set forth in the Financing Commitments. Notwithstanding anything in this Agreement to the contrary, the Financing Commitments may be superseded at the option of Transocean with the consent of GlobalSantaFe after the date of this Agreement but prior to the Effective Time by new Financing Commitments, including financing commitments from one or more additional or other parties, in accordance with this Section 7.16 (the "New Financing Commitments"). In such event, the term "Financing Commitment" as used herein shall be deemed to include the New Financing Commitments to the extent then in effect.

        (b)   Transocean and GlobalSantaFe shall use their respective reasonable best efforts to obtain the financing on the terms and conditions described in the Financing Commitments or terms more favorable to Transocean. Transocean and, at the direction and guidance of Transocean, GlobalSantaFe shall use their reasonable best efforts (consistent with the terms and obligations of each party under this Agreement) (i) to negotiate definitive agreements with respect thereto on the terms and conditions contained in the Financing Commitments and (ii) to consummate the Financing at or prior to the Closing. Each party shall give the other prompt notice upon becoming aware of any termination of the

A-55



Financing Commitments. Transocean shall keep GlobalSantaFe informed on a reasonably current basis and in reasonable detail of the status of its efforts to arrange the Financing. In the event that either party becomes aware of any event or circumstance that makes procurement of any portion of the Financing unlikely to occur in the manner or from the sources contemplated in the Financing Commitments, that party shall notify the other party, and Transocean and, at the direction and guidance of Transocean, GlobalSantaFe shall use their respective reasonable best efforts to assist in arranging as promptly as practicable any such portion from alternative sources on terms and conditions substantially no less favorable to Transocean. Transocean shall take and shall use reasonable best efforts to cause its Subsidiaries, and shall cause each of its and their respective Representatives, including legal and accounting, to take all actions reasonably necessary in connection with the Financing. At the reasonable request of Transocean, GlobalSantaFe shall provide, and shall use reasonable best efforts, consistent with the terms of and the obligations of each party under this Agreement, to cause its Subsidiaries, and shall cause each of its and their respective Representatives, including legal and accounting, to provide all cooperation reasonably requested by Transocean in connection with the Financing. In performing its respective foregoing obligations under this Section 7.16, each of Transocean, Transocean's Subsidiaries, GlobalSantaFe and GlobalSantaFe's Subsidiaries shall use its reasonable best efforts to (i) provide reasonably required information relating to that party and its Subsidiaries to the parties providing the Financing, (ii) participate in meetings, drafting sessions and due diligence sessions in connection with the Financing, (iii) assist in the preparation of (A) any offering documents for any portion of the Financing, and (B) materials for rating agency presentations, including execution and delivery of customary representation letters in connection with bank information memoranda, (iv) reasonably cooperate with the marketing efforts for any portion of the Financing, (v) execute and deliver (or use reasonable best efforts to obtain from its advisors), and cause its Subsidiaries to execute and deliver (or obtain from its advisors), customary certificates (including a certificate of the principal financial officer of Transocean, GlobalSantaFe or any Subsidiary of Transocean or GlobalSantaFe with respect to solvency matters), accounting comfort letters (including consents of accountants for use of their reports in any materials relating to the Financing), legal opinions, surveys, title insurance or other documents and instruments relating to guarantees, the pledge of collateral and other matters ancillary to the Financing as may be reasonably necessary in connection with the Financing, (vi) enter into one or more secured or unsecured credit or other agreements on terms satisfactory to Transocean and that are reasonably necessary in connection with the Financing immediately prior to the Effective Time, (vii) as promptly as practicable, furnish Transocean and its Financing sources with all financial and other information regarding Transocean, GlobalSantaFe and their respective Subsidiaries as may be reasonably necessary of a type generally used in connection with a syndicated bank financing as well as a registered public offering or an offering pursuant to Rule 144A of the Securities Act, (viii) take all actions reasonably necessary in connection with the pay off of existing indebtedness and the release of related Liens (including the prepayment of Transocean's or GlobalSantaFe's existing indebtedness on or prior to the Closing Date), and (ix) take all corporate actions, subject to the occurrence of the Closing, reasonably necessary to permit the consummation of the Financing and the direct borrowing or incurrence of all of the proceeds of the Financing, by Transocean immediately following the Effective Time; provided, however, that no obligation of Transocean or GlobalSantaFe or any of their respective Subsidiaries under any such agreement, certificate, document or instrument shall be required to be effective until the Effective Time and, other than commitment fees with respect to the Financing Commitments, none of Transocean, GlobalSantaFe or any of their respective Subsidiaries shall be required to pay any commitment or other similar fee or incur any liability in connection with the Financing prior to the Effective Time. Transocean shall pay two-thirds, and GlobalSantaFe shall pay one-third, of all reasonable out-of-pocket third party costs incurred by Transocean, GlobalSantaFe or any of their respective Subsidiaries in connection with this Section 7.16 and shall promptly (and in any event no later than five business days), upon request by a party, reimburse the other party therefor.

A-56


        (c)   Notwithstanding anything in this Agreement to the contrary, in the event that the Merger, the Reclassification and/or the other transactions contemplated by this Agreement are not consummated due to circumstances arising out of any failure to obtain the Financing, no party shall have any liability to any other party arising out of such failure; provided, however, that the foregoing shall not relieve Transocean or GlobalSantaFe of its respective obligation to use reasonable best efforts to obtain the Financing to the extent required by Section 7.16(b). Each party acknowledges that (i) notwithstanding anything in this Agreement to the contrary, Transocean is not intended to have any greater risk or liability than GlobalSantaFe with respect to any failure to obtain the Financing or with respect to any other matters contemplated by this Section 7.16 and (ii) no other party would have entered into this Agreement but for the agreement of the parties set forth in this Section 7.16(c).

        Section 7.17    Tax Treatment.    

        (a)   Prior to and at the Effective Time, each party hereto shall use its reasonable best efforts to cause the Merger to qualify as a reorganization described in Section 368(a) of the Code, and shall not take any action reasonably likely to cause the Merger not to so qualify. Without limiting the foregoing, the parties will take all actions required for Merger Sub, at the Effective Time, to be disregarded as an entity separate from its owner, Transocean, for United States federal tax purposes.

        (b)   Each of GlobalSantaFe and Transocean shall use its reasonable best efforts to obtain the opinions referred to in sections 8.2(b) and 8.3(b), respectively, including by executing officers' certificates substantially in the form of Exhibits 8.2 and 8.3, respectively.

        (c)   If this Agreement is terminated by GlobalSantaFe or Transocean pursuant to Section 9.2(b) or by Transocean pursuant to Section 9.4(b) (in either case other than in any circumstances where a fee is payable under Section 9.5(a)), then GlobalSantaFe shall reimburse Transocean for its third party costs and expenses in connection with this transaction, up to a maximum of $30 million. If this Agreement is terminated by GlobalSantaFe or Transocean pursuant to Section 9.2(c) or by GlobalSantaFe pursuant to Section 9.3(b) (in either case other than in any circumstances where a fee is payable under Section 9.5(b)), then Transocean shall reimburse GlobalSantaFe for its third party costs and expenses in connection with this transaction, up to a maximum of $30 million. In circumstances where this Section 9.5(c) requires a reimbursement of costs and expenses, the reimbursing party shall reimburse the other party for such costs and expenses on the later of (i) the day that is three business days after the date of termination of this Agreement and (ii) the day that is three business days after the delivery of documentation of such costs and expenses. In the event the payment of a fee by GlobalSantaFe is required pursuant to Section 9.5(a)(i)(A)(1)(b) or the payment of a fee by Transocean is required pursuant to Section 9.5(b)(i)(A)(1)(b), and such party has already reimbursed Transocean or GlobalSantaFe, respectively, for its third party costs and expenses pursuant to this Section 9.5(c), the amount of such costs and expenses so reimbursed will be offset against the fee payable.

        (d)   In the event of termination of this Agreement and the abandonment of the Merger and the Reclassification pursuant to this Article 9, all obligations of the parties hereto shall terminate, except the obligations of the parties pursuant to this Section 9.5, the last sentence of Section 7.6, Section 7.12

The Confidentiality and Standstill Agreement shall survive any termination of this Agreement, and the provisions of the Confidentiality and Standstill Agreement shall apply to all information and material delivered by any party hereunder.

        (e)   In the event that GlobalSantaFe shall fail to pay the termination fee and/or expenses when due, or Transocean shall fail to pay the termination fee and/or expenses when due, as contemplated in either case by Section 9.5, such fee and/or expenses, as the case may be, shall accrue interest for the period commencing on the date such fee and/or expenses, as the case may be, became past due, at a rate equal to the rate of interest publicly announced by Citibank, in the City of New York, from time to time during such period, as such bank's prime lending rate. In addition, if either party shall fail to pay the fee and/or expenses, as the case may be, when due, such owing party shall also pay to the owed party all of the owed party's costs and expenses (including attorneys' fees) in connection with efforts to collect such fee and/or expenses, as the case may be. Transocean and GlobalSantaFe acknowledge that the fees, expense reimbursement and the other provisions of this Section 9.5 are an integral part of the Merger and the Reclassification and that, without these agreements, Transocean and GlobalSantaFe would not enter into this Agreement.

        Section 9.6    Extension; Waiver.    At any time prior to the Effective Time, each party may by action taken by its Board of Directors or by any committee of the Board of Directors, or any director or officer, properly delegated by the Board of Directors, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (b) waive any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions for the benefit of such party contained herein.

Notwithstanding anything contained in this Agreement to the contrary, except for (a) the provisions of Section 7.13, (b) the right of GlobalSantaFe shareholders to receive the GlobalSantaFe Merger Consideration after the Closing (a claim with respect to which may not be made unless and until the Closing shall have occurred), (c) the right of Transocean shareholders to receive the Transocean Reclassification Consideration after the Closing (a claim with respect to which may not be made unless and until the Closing shall have occurred), (d) the right of each party, on behalf of its shareholders, to pursue damages in the event of the other party's willful breach of this Agreement, or fraud, which right is hereby acknowledged and agreed, nothing in this Agreement, expressed or implied, is intended to confer on any Person other than the parties hereto or their respective heirs, successors, executors, administrators and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement.

        Section 10.4    Entire Agreement.    This Agreement, the exhibits to this Agreement, the Transocean Disclosure Letter, the GlobalSantaFe Disclosure Letter and any documents delivered by the parties in connection herewith constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings among the parties with respect thereto, except that the Confidentiality and Standstill Agreement shall continue in effect.

The parties agree that in the event that it becomes reasonably apparent to both parties that the consummation of a direct amalgamation of GlobalSantaFe with Transocean by way of a scheme of arrangement is more practicable than the Merger, the parties agree to take such actions as shall be reasonably necessary to restructure the transaction contemplated hereby accordingly, and that thereafter all references herein to the "Merger" shall be deemed to refer to such alternate scheme. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of view to Transocean Inc. (the "Company"), after taking into account the Proposed Reclassification (as defined below), of the GlobalSantaFe Merger Consideration (as defined below) in the aggregate to be paid by the Company in respect of each share of ordinary stock, par value $0.01 per share (the "GlobalSantaFe Ordinary Shares"), of GlobalSantaFe Corporation ("GlobalSantaFe") pursuant to the Agreement and Plan of Merger, dated as of July 21, 2007 (the "Agreement"), by and among the Company, Transocean Worldwide Inc., a wholly owned subsidiary of the Company ("Transocean Merger Sub"), and GlobalSantaFe. Pursuant to the Agreement, GlobalSantaFe will be merged with and into Transocean Merger Sub (the "Merger") and each outstanding GlobalSantaFe Ordinary Share will be converted into the right to receive (i) 0.4757 ordinary shares, par value $0.01 per share (the "Company Ordinary Shares"), of the Company (the "GlobalSantaFe Share Consideration") and (ii) an amount in cash equal to $22.46 (the "GlobalSantaFe Cash Consideration", and, together with the GlobalSantaFe Share Consideration, the "GlobalSantaFe Merger Consideration"). The Agreement provides that immediately prior to consummation of the Merger, each outstanding Company Ordinary Share will be reclassified as and converted into the right to receive 0.6996 Company Ordinary Shares and $33.03 in cash (the "Proposed Reclassification"), as more fully described in the Agreement.

Goldman, Sachs & Co. and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the transaction contemplated by the Agreement (the "Transaction"). We expect to receive fees for our financial advisory services in connection with the Transaction, all of which are contingent upon consummation of the Transaction, and the Company has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement. An affiliate of Goldman Sachs is expected to provide acquisition financing to the Company in connection with the Transaction, for which we will receive customary fees.

B-1



In addition, we have provided and are currently providing certain investment banking and other financial services to the Company and its affiliates, including having acted (i) as co-manager of a public offering of 17,940,000 Class A Shares of TODCO, an affiliate of the Company, in September 2004, (ii) as co-manager of a public offering of 14,950,000 Class A Shares of TODCO in December 2004, (iii) as dealer manager in connection with a tender offer for the Company's 8% debentures due 2027 (aggregate principal amount $143,000,000) in December 2004, (iv) as a participant in a revolving credit facility extended to the Company (aggregate principal amount $1,000,000,000) in July 2005, (v) as agent in connection with repurchases by the Company of Company Ordinary Shares in December 2005 and from time to time, and (vi) as lead manager of a public offering of the Company's floating rate notes due September 2008 (aggregate principal amount $1,000,000,000) in September 2006. We have provided certain investment banking and other financial services to GlobalSantaFe and its affiliates from time to time, including having acted (i) as bookrunner of a public offering of 23,500,000 GlobalSantaFe Ordinary Shares in April 2005 and (ii) as participant in a revolving credit facility extended to GlobalSantaFe (aggregate principal amount $500,000,000) in August 2006. We also may provide investment banking and other financial services to the Company, GlobalSantaFe and their respective affiliates in the future. In connection with the above-described services we have received, and may receive, compensation.

Goldman, Sachs & Co. is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman, Sachs & Co. and its affiliates may provide such services to the Company, GlobalSantaFe and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of the Company and GlobalSantaFe for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company and GlobalSantaFe for the five fiscal years ended December 31, 2006; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and GlobalSantaFe; certain other communications from the Company and GlobalSantaFe to their respective stockholders; certain internal financial analyses and forecasts for the Company prepared by its management and certain financial analyses and forecasts for GlobalSantaFe prepared by the management of the Company (the "Forecasts"), including certain cost savings and operating synergies projected by the management of the Company to result from the Transaction (the "Synergies"). We also have held discussions with members of the senior management of the Company and GlobalSantaFe regarding their assessment of the strategic rationale for, and the potential benefits of, the Transaction and the past and current business operations, financial condition and future prospects of their respective companies. In addition, we have reviewed the reported price and trading activity for Company Ordinary Shares and GlobalSantaFe Ordinary Shares, compared certain financial and stock market information for GlobalSantaFe and the Company with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the oilfield services industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as we considered appropriate.

For purposes of rendering this opinion, we have relied upon and assumed, without assuming any responsibility for independent verification, the accuracy and completeness of all of the financial, accounting, legal, tax and other information provided to, discussed with or reviewed by us. In that regard, we have assumed with your consent that the Forecasts, including the Synergies, have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company. In addition, we have not made an independent evaluation or appraisal of

B-2



the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company or GlobalSantaFe or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal. We also have assumed that all governmental, regulatory or other consents or approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or GlobalSantaFe or on the expected benefits of the Transaction in any way meaningful to our analysis. Our opinion does not address any legal, regulatory, tax or accounting matters.

Our opinion does not address the underlying business decision of the Company to engage in the Transaction or the relative merits of the Transaction as compared to any strategic alternatives that may be available to the Company, nor are we expressing any opinion as to the Proposed Reclassification or the prices at which the Company Ordinary Shares will trade at any time. Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof and we assume no responsibility for updating, revising or reaffirming this opinion based on circumstances, developments or events occurring after the date hereof. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of Company Ordinary Shares should vote with respect to such Transaction, the Proposed Reclassification or any other matter.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, and after taking into consideration the Proposed Reclassification, the GlobalSantaFe Merger Consideration to be paid by the Company to the holders of outstanding GlobalSantaFe Ordinary Shares is fair from a financial point of view to the Company.

Very truly yours,

Board of Directors
GlobalSantaFe Corporation

Houston, TX 77079

Members of the Board:

        We understand that GlobalSantaFe Corporation (the "Company") intends to enter into a transaction (the "Proposed Transaction") with Transocean, Inc. ("Transocean"), pursuant to which (i) the Company will merge with and into a wholly owned subsidiary of Transocean ("Merger Sub"), with the Merger Sub surviving the merger, and (ii) upon the effectiveness of the merger, each share of common stock of the Company then issued and outstanding, other than shares to be cancelled pursuant to the Agreement (as defined below), will be converted into the right to receive 0.4757 shares of the common stock of Transocean and $22.46 in cash (the "Consideration"). We also understand that, pursuant to the Agreement, immediately prior to the effectiveness of the merger, each share of common stock of Transocean then issued and outstanding will be reclassified into the right to receive 0.6996 shares of the common stock of Transocean and $33.03 in cash. The terms and conditions of the Proposed Transaction are set forth in more detail in the Agreement and Plan of Merger dated as of July 21, 2007 among the Company, Transocean and Merger Sub (the "Agreement").

        We have been requested by the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company's stockholders of the Consideration to be offered to such stockholders in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company's underlying business decision to proceed with or effect the Proposed Transaction.

        In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and the specific terms of the Proposed Transaction; (2) publicly available information concerning the Company and Transocean that we believe to be relevant to our analysis, including the Annual Reports on Forms 10-K for the fiscal year ended December 31, 2006 and Quarterly Reports on Forms 10-Q for the quarter ended March 31, 2007 for each of the Company and Transocean; (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including financial projections of the Company prepared by the management of the Company; (4) financial and operating information with respect to the business, operations and prospects of Transocean furnished to us by the Company, including financial projections of Transocean prepared by the management of the Company; (5) the trading histories of the Company's common stock and Transocean's common stock from July 20, 2004 to July 20, 2007 and a comparison of those trading histories with each other and with those of other companies that we deemed relevant; (6) a comparison of the historical financial results and present financial condition of the Company and Transocean with each other and with those of other companies that we deemed relevant; (7) the potential pro forma impact of the Proposed Transaction on the current and future financial performance of the combined company, including the amounts and timing of the cost savings and operating synergies expected to result from the Proposed Transaction (the "Expected Synergies"); (8) published estimates by independent equity research analysts with respect to the future financial performance of the Company and Transocean; and (9) the relative contributions of the Company and Transocean to the current and future financial performance of the combined company on a pro forma basis. In addition, we have had discussions with the management of the Company and Transocean concerning their respective

C-1



businesses, operations, assets, liabilities, financial condition and prospects and have undertaken such other studies, analyses and investigations as we deemed appropriate.

        In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and have further relied upon the assurances of the managements of the Company and Transocean that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of the Company, upon advice of the Company, we have assumed that such financial projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company and that the Company will perform substantially in accordance with such projections. With respect to the financial projections of Transocean, upon advice of the Company, we have assumed that such financial projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of Transocean and that Transocean will perform substantially in accordance with such projections. With respect to the Expected Synergies, we have assumed that the amount and timing of the Expected Synergies are reasonable as estimated by the management of the Company and we also have assumed that the Expected Synergies will be realized substantially in accordance with such estimates. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company or Transocean and have not made or relied upon any evaluations or appraisals of the assets or liabilities of the Company or Transocean. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter.

        In addition, we express no opinion as to the prices at which shares of (i) the Company or Transocean will trade at any time following the announcement of the Proposed Transaction or (ii) Transocean will trade at any time following the consummation of the Proposed Transaction.

        Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the Consideration to be offered to the stockholders in the Proposed Transaction is fair to such stockholders.

        We have acted as financial advisor to the Company in connection with the Proposed Transaction and will receive a fee for our services a portion of which is payable with respect to the delivery of this opinion and the remainder of which is contingent upon the consummation of the Proposed Transaction. In addition, the Company has agreed to reimburse our expenses and indemnify us for certain liabilities that may arise out of the rendering of this opinion. We also have performed various investment banking services for the Company in the past and have received customary fees for such services and we expect to perform various investment banking services for Transocean in the future for which we expect to receive customary fees. In the ordinary course of our business, we actively trade in the debt and equity securities of the Company and Transocean for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. In addition, the Company has requested and we are providing a commitment for a portion of the financing necessary to finance the Proposed Transaction, and we will receive customary fees in connection therewith.

        This opinion is for the use and benefit of the Board of Directors of the Company and is rendered to the Board of Directors in connection with its consideration of the Proposed Transaction. This opinion is not intended to be and does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the Proposed Transaction.

    Very truly yours,

Gentlemen:

        We understand that GlobalSantaFe Corporation ("the Company"), Transocean Inc. ("Transocean") and an indirectly wholly-owned subsidiary of Transocean ("Transocean Merger Sub"), propose to enter into an Agreement and Plan of Merger by and among the Company, Transocean and Transocean Merger Sub, substantially in the form of the draft dated July 18, 2007 (the "Merger Agreement"), which provides, among other things, for the merger ("the Merger") of the Company with and into Transocean Merger Sub. Pursuant to the Merger, the Company will become a wholly-owned subsidiary of Transocean, and each ordinary share, par value $0.01 per share (the "Company Common Stock"), of the Company, other than shares held in treasury or held by Transocean or any of the Company's wholly-owned subsidiaries, will be exchanged for 0.4757 ordinary shares, par value $0.01 per share, of Transocean (the "Transocean Common Stock") and cash consideration of $22.46 per share (together the "Merger Consideration"). The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

        You have asked our opinion as to whether the Merger Consideration to be received by the holders of shares of the Company Common Stock pursuant to the Merger Agreement is fair from a financial point of view to such holders.

        In arriving at our opinion, we have reviewed and analyzed, among other things, the following:

D-1


        In connection with our review, we have not independently verified any of the foregoing information and have relied on it being complete and accurate in all material respects. With respect to the financial forecasts, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the Company's management as to the future financial performance of the Company and Transocean. We have assumed that the Merger will be consummated in accordance with the terms set forth in the Merger Agreement without any waiver, amendment or delay of any terms or conditions. We have assumed that in connection with the receipt of all necessary governmental, regulatory or other approvals and consents required for the Merger, no delays, limitations, conditions or restrictions will be imposed that would have a material adverse effect on the contemplated benefits expected to be derived by the Merger. We are not legal, tax or regulatory advisors and have relied upon, without independent verification, the assessment of the Company and its legal, tax and regulatory advisors with respect to such matters. Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof may affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion. We were not requested to, and did not, solicit indications of interest in acquiring all or any part of the Company.

        Simmons & Company International ("Simmons") is an internationally recognized investment banking firm that specializes in the energy industry. Simmons is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, secondary distributions of listed and unlisted securities and private placements.

        We have been engaged by the Company to perform a financial analysis of the Merger for the purpose of rendering this opinion and will receive a fee for so doing. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of our engagement. In the past, we have acted as financial advisor to the Company and to Transocean and we may act as financial advisor to Transocean with respect to future transactions.

D-2



        In the ordinary course of our business, we actively trade debt and equity securities for our own account and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities of the Company and Transocean.

        It is understood that this letter is for the information of the Board of Directors of Company and is not to be quoted or referred to, in whole or in part, in any registration statement, prospectus, or proxy statement (except for the registration statement, proxy statement, or prospectus related to the Merger as provided below), or in any other written document used in connection with the offering or sale of securities, nor shall this letter be used for any other purposes, without Simmons' prior written consent. It is further understood that, if the opinion is included in the registration statement, proxy statement or prospectus in connection with the Merger, the opinion will be reproduced in such registration statement, proxy statement or prospectus in full, and any description of or reference to Simmons or summary of the opinion in such registration statement, proxy statement or prospectus will be in a form acceptable to Simmons and its counsel.

        Our opinion does not address the Company's underlying business decision to pursue the Merger or the relative merits of the Merger as compared to any alternative business strategies that might exist for the Company. Our opinion does not constitute a recommendation as to how the holders of shares of the Company's Common Stock should vote with respect to the Merger.

        Based upon and subject to the foregoing, including the various assumptions and limitations set forth herein, it is our opinion that, as of the date hereof, the consideration to be received by the holders of the Company's ordinary shares, as set forth in the Merger Agreement, is fair to such holders from a financial point of view.

Very truly yours,

        3.3   No holder of Ordinary Shares or any other shares (unless such right is expressly conferred on the holders of such shares) shall, by reason of such holding, have any preemptive or preferential right to subscribe to or purchase any shares or any notes, debentures, bonds or other securities of the Company, whether or not the issuance of any such shares, notes, debentures, bonds or other securities would adversely affect the dividend, voting or any other rights of such holder.

        3.4   The Company may, insofar as may be permitted by law, pay a commission to any person in consideration of such person or any other person subscribing or agreeing to subscribe whether absolutely or conditionally for any shares. Such commissions may be satisfied by the payment of cash or the lodgment of fully or partly paid-up shares or partly in one way and partly in the other. The Company may also on any issue of shares pay such brokerage as may be lawful.

        3.5   The Directors may issue fractions of a share of any class or series of shares, and, if so issued, a fraction of a share (calculated to three decimal points) shall be subject to and carry the corresponding fraction of liabilities (whether with respect to any unpaid amount thereon, contribution, calls or otherwise), limitations, preferences, privileges, qualifications, restrictions, rights (including, without limitation, voting and participation rights) and other attributes of a whole share of the same class or series of shares. If more than one fraction of a share of the same class or series is issued to or acquired by the same member such fractions shall be accumulated. For the avoidance of doubt, in these Articles the expression "share" shall include a fraction of a share.

        3.6   Any shares which have been redeemed or otherwise repurchased by the Company shall have the status of authorized but unissued shares and may be subsequently issued in accordance with the Memorandum and these Articles.

        3.7   The Board of Directors shall have the fullest powers permitted by law to pay all or any monies in respect of the redemption or purchase of any shares out of the Company's share capital and share premium account.

IV. ORDINARY SHARES

        4.1   The Board of Directors may allot, issue or grant any option, right, warrant or other security exercisable for, convertible into or exchangeable for, or otherwise dispose of, any shares or securities of the Company at such times and on such terms as it deems proper. Upon approval of the Board of Directors, such number of Ordinary Shares, or other shares or securities of the Company, as may be required for such purpose shall be reserved for issuance in connection with any option, right, warrant or other security of the Company or any other person that is exercisable for, convertible into, exchangeable for or otherwise issuable in respect of such Ordinary Shares or other shares or securities of the Company. Notwithstanding the generality of the foregoing, the Board of Directors is expressly authorized and empowered to implement or effect at its sole discretion the issuance of a preferred share purchase right to be attached to each issued Ordinary Share with such terms and for such purposes, including the influencing of takeovers, as may be described in a rights agreement between the Company and a rights agent.

        4.2   Subject to the provisions of applicable law and any rights granted to any series or class of shares other than Ordinary Shares, the holders of Ordinary Shares shall have and possess the exclusive right to notice of general meetings of the Company and the exclusive power to vote on resolutions put to general meetings of the Company.

V. OTHER CLASSES OR SERIES OF SHARES

        5.1   The Board of Directors is authorized, without obtaining any vote or consent of the holders of any class or series of shares unless expressly provided by the terms of issue of a class or series, subject to any limitations prescribed by law, to provide from time to time for the issuance of other classes or series of shares and, in accordance with applicable procedures of the Statute, to establish the characteristics of each class or series including, without limitation, the following:

F-4


VI. VARIATION OF RIGHTS OF SHARES

        6.1   (a) If at any time the share capital of the Company is divided into different classes or series of shares, the rights attached to any class or series (unless otherwise provided by the terms of issue of the shares of that class) may, whether or not the Company is being wound-up, be varied and amended with the consent in writing of the holders of all of the issued shares of that class or series, or with the sanction of a Special Resolution passed at a separate general meeting of the holders of such class or series.

        (b)   The provisions of these Articles relating to general meetings of the Company shall apply to every such separate general meeting of the holders of one class or series of shares (unless otherwise expressly provided by the terms of issue of the shares of that class or series).

        (c)   Separate general meetings of the holders of a class or series of shares or the seeking of a consent of the holders of a class or series of shares may only be called at the direction of the Board of Directors (unless otherwise expressly provided by the terms of issue of the shares of that class or series). Nothing in this Article VI gives any Member or group of Members the right to call a class or series meeting or demand a class or series vote or consent.

        6.2   The rights conferred upon the holders of the shares of any class or series issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the shares of that class or series, be deemed to be varied by the creation or issue of further shares ranking in any respect prior to or pari passu therewith. The rights of the holders of Ordinary Shares shall not be deemed to be varied by the creation or issue of shares with preferred or other rights, which may be effected by the Board of Directors as provided in these Articles without any vote or consent of the holders of Ordinary Shares.

VII. REDEMPTION AND REPURCHASE

        7.1   The Ordinary Shares are not redeemable by the Company or the holder. Subject as set out herein, the Company is authorized to purchase any issued Ordinary Shares in such circumstances and on such terms as shall be agreed by the Company and the holder thereof, subject always to the laws of the Cayman Islands, and the Company may deduct from the price for such shares the aggregate amount of any outstanding debts, liabilities and engagements to or with the Company (whether presently payable or not) by the holder of such shares, either alone or jointly with any other person,

F-5


whether a Member or not. Without limiting the foregoing, the Company may, from time to time, upon the agreement of a Member, purchase all or part of the Ordinary Shares of any such Member, whether or not the Company has made a similar offer to all or any of the other Members.

VIII. TRANSFER OF SHARES

        8.1   Transfers of shares shall be registered on the records maintained by or on behalf of the Company for such purpose upon (i) if certificates have been issued in respect of the shares, surrender to the Company or its transfer agent of such certificate or certificates in respect of the shares requested to be transferred, the transfer provisions on the certificate or certificates being duly completed, or a separate accompanying instrument of transfer in such form as the Board of Directors approves, or (ii) if shares are not represented by certificates, upon delivery of an instrument of transfer in such form as the Board of Directors approves, in each case together with such evidence of the payment of transfer taxes and compliance with other provisions of law as the Company or its transfer agent may require.

        8.2   Subject to the rules of any stock exchange on which the shares in question may be listed and except as otherwise expressly provided by the terms of issue of the shares of any class or series, the Board of Directors may, in its absolute discretion and without assigning any reason therefore, decline to register any transfer of any share. The registration of transfers may be suspended at such times and for such periods as the Board of Directors may from time to time determine provided always that such registration shall not be suspended for more than 30 days in any year.

IX. NONRECOGNITION OF TRUSTS

        9.1   The Company shall be entitled to treat the holder of record of any share as the holder in fact thereof and accordingly shall not be bound to recognize any equitable or other claim to or interest in such share on the part of any other person, whether or not it shall have express or other notice thereof, except as expressly provided by law. The Company shall not be required to recognize any person as holding any share upon any trust, and the Company shall not be bound by or be compelled in any way to recognize (even when having notice thereof) any equitable, contingent, future or partial interest in any share, any interest in any fractional part of a share (subject to Article 3.5), or (except only as is otherwise provided by these Articles or the Statute) any other rights in respect of any share except an absolute right to the entirety thereof in the registered holder.

X. LIEN ON SHARES

        10.1 The Company shall have a first and paramount lien and charge on all shares (not being a fully paid share) registered in the name of a Member (whether solely or jointly with others) for all debts, liabilities or engagements to or with the Company (whether presently payable or not) by such Member or his estate, either alone or jointly with any other person, whether a Member or not, but the Board of Directors may at any time declare any share to be wholly or in part exempt from the provisions of this Article X. The registration of a transfer of any such share shall operate as a waiver of the Company's lien (if any) thereon. The Company's lien (if any) on a share shall extend to all dividends, redemptions or other monies payable in respect thereof.

        10.2 The Company may sell, in such manner as the Board of Directors deems fit, any shares on which the Company has a lien, except as set forth in this Article X. Unless otherwise permitted in the instrument creating such lien, no such sale shall be made unless a sum in respect of which the lien exists is presently payable. Unless otherwise permitted in the instrument creating such lien, no such sale shall be made until the expiration of 14 days after a notice in writing, stating and demanding payment of such part of the amount in respect of which the lien exists as is presently payable, has been given to the holder or holders for the time being of the shares, or the person, of which the Company has notice, entitled thereto by reason of his death or bankruptcy.

F-6


        10.3 To give effect to any such sale, the Board of Directors may authorize some person to transfer the shares sold to the purchaser thereof. The purchaser shall be registered as the holder of the shares included in any such transfer, and he shall not be bound to see to the application of the purchase money, nor shall his title to the shares be affected by any irregularity or invalidity in the proceedings in reference to the sale.

        10.4 The proceeds of the sale of such shares shall be received by the Company and applied in payment of such part of the amount in respect of which the lien exists as is presently payable, and the residue, if any, shall (subject to a like lien for sums not presently payable as existed upon the shares before the sale) be paid to the person entitled to the shares at the date of the sale.

XI. CALL ON SHARES

        11.1 (a) The Board of Directors may from time to time make calls upon the Members in respect of any monies unpaid on their shares (whether on account of the nominal value of the shares or by way of premium or otherwise) and not by the conditions of allotment thereof made payable at fixed terms; and each Member shall, subject to receiving at least 14 days' notice (or some shorter period of notice as may have been authorized by the terms on issue of the shares) specifying the time or times of payment, pay to the Company at the time or times so specified the amount called on the shares. A call may be revoked or postponed as the Board of Directors may determine. A call may be made payable by installments.

        (b)   A call shall be deemed to have been made at the time when the resolution of the Board of Directors authorizing such call was passed unless otherwise provided by the Board of Directors.

        (c)   The joint holders of a share shall be jointly and severally liable to pay all calls in respect thereof.

        11.2 If a sum called in respect of a share is not paid before or on the day appointed for payment thereof, the persons from whom the sum is due shall pay interest on the sum from the day appointed for payment thereof to the time of actual payment at such rate not exceeding ten percent (10%) per annum as the Board of Directors may determine, but the Board of Directors shall be at liberty to waive payment of such interest either wholly or in part.

        11.3 Any sum which by the terms of a share becomes payable on allotment or at any fixed date, whether on account of the nonfinal value of the share or by way of premium or otherwise, shall for the purposes of these Articles be deemed to be a call duly made, notified and payable on the date on which by the terms of issue the same becomes payable, and in the case of nonpayment, all the relevant provisions of these Articles as to payment of interest, forfeiture or otherwise shall apply as if such sum had become payable by virtue of a call duly made and notified.

        11.4 The Board of Directors may, on the issue of shares, differentiate between the holders as to the amount of calls or interest to be paid and the times of payment.

        11.5 (a) The Board of Directors may, if it thinks fit, receive from any Member willing to advance the same, all or any part of the monies uncalled and unpaid upon any shares held by him, and upon all or any of the monies so advanced may (until the same would but for such advances, become payable) pay interest at such rate as may be agreed upon between the Company and the Member paying such sum in advance.

        (b)   No such sum paid in advance of calls shall entitle the Member paying such sum to any portion of a dividend declared in respect of any period prior to the date upon which such sum would, but for such payment, become presently payable.

F-7



XII. FORFEITURE OF SHARES

        12.1 (a) If a Member fails to pay any call or installment of a call or to make any payment required by the terms of issue on the day appointed for payment thereof, the Board of Directors may, at any time thereafter during such time as any part of the call, installment or payment remains unpaid, give notice requiring payment of so much of the call, installment or payment as is unpaid, together with any interest which may have accrued and all expenses that have been incurred by the Company by reason of such nonpayment. Such notice shall name a day (not earlier than the expiration of 14 days from the date of giving of the notice) on or before which the payment required by the notice is to be made and shall state that, in the event of nonpayment at or before the time appointed, the shares in respect of which such notice was given will be liable to be forfeited.

        (b)   If the requirements of any such notice as aforesaid are not complied with, any share in respect of which the notice has been given may at any time thereafter, before the payment required by the notice has been made, be forfeited by a resolution of the Board of Directors to that effect. Such forfeiture shall include all dividends declared in respect of the forfeited share and not actually paid before the forfeiture.

        (c)   A forfeited share may be sold or otherwise disposed of on such terms and in such manner as the Board of Directors deems fit, and at any time before a sale or disposition the forfeiture may be canceled on such terms as the Board of Directors thinks fit.

        12.2 A person whose shares have been forfeited shall cease to be a Member in respect of the forfeited shares, but shall, notwithstanding, remain liable to pay to the Company all monies which, at the date of forfeiture, were payable by him to the Company in respect of the shares together with interest thereon, but his liability shall cease if and when the Company shall have received payment in full of all monies whenever payable in respect of the shares.

        12.3 A certificate in writing under the hand of the President or any Vice President and the Secretary of the Company that a share in the Company has been duly forfeited on a date stated in the declaration shall be conclusive evidence of the fact therein stated as against all persons claiming to be entitled to the share. The Company may receive the consideration given for the share on any sale or disposition thereof and may execute a transfer of the share in favor of the person to whom the share is sold or disposed of, and that person shall thereupon be registered as the holder of the share and shall not be bound to see to the application of the purchase money, if any, nor shall that person's title to the share be affected by any irregularity or invalidity in the proceedings in reference to the forfeiture, sale or disposal of the share.

        12.4 The provisions of these Articles as to forfeiture shall apply in the case of nonpayment of any sum which, by the terms of issue of a share, becomes payable at a fixed time, whether on account of the nominal value of the share or by way of premium as if the same had been payable by virtue of a call duly made and notified.

XIII. TRANSMISSION OF SHARES ON DEATH OR BANKRUPTCY

        13.1 In case of the death of a Member who is a natural person, the survivor or survivors, where the deceased was a joint holder, and the legal personal representatives of the deceased, where he was a sole holder, shall be the only persons recognized by the Company as having any title to his interest in the shares, but nothing herein contained shall release the estate of any such deceased holder from any liability in respect of any shares which had been held by him solely or jointly with other persons.

        13.2 (a) Any person becoming entitled to a share in consequence of the death or bankruptcy of a Member (or in any other way than by transfer) may, upon such evidence being produced as may from time to time be required by the Board of Directors and subject as hereinafter provided, elect either to be registered himself as holder of the share or to make such transfer of the share to such other person

F-8


nominated by him as the deceased or bankrupt person could have made and to have such person registered as the transferee thereof, but the Board of Directors shall, in either case, have the same right to decline or suspend registration as they would have had in the case of a transfer of the share by that Member before his death or bankruptcy, as the case may be.

        (b)   If the person so becoming entitled shall elect to be registered himself as holder he shall deliver or send to the Company a notice in writing signed by him stating that he so elects.

        13.3 A person becoming entitled to a share by reason of the death or bankruptcy of the holder (or in any other case than by transfer) shall be entitled to the same dividends and other advantages to which he would be entitled if he were the registered holder of the share, except that he shall not, before being registered as a Member in respect of the share, be entitled in respect of it to exercise any right conferred by membership in relation to meetings of the Company; provided, however, that the Board of Directors may at any time give notice requiring any such person to elect either to be registered himself or to transfer the share and if the notice is not complied with within 90 days the Board of Directors may thereafter withhold payment of all dividends, bonuses or other monies payable in respect of the share until the requirements of the notice have been complied with.

XIV. AMENDMENT OF MEMORANDUM OF ASSOCIATION, CHANGE OF LOCATION OF REGISTERED OFFICE AND ALTERATION OF CAPITAL

        14.1 (a) Subject to and insofar as permitted by the provisions of the Statute, the Company may from time to time by Special Resolution alter or amend the Memorandum and, without restricting the generality of the foregoing, the Company may by Ordinary Resolution:

        (b)   All new shares created hereunder shall be subject to the same provisions with reference to the payment of calls, liens, transfer, transmission, forfeiture and otherwise as the shares in the original share capital.

        (c)   Subject to the provisions of the Statute, the Company may by Special Resolution reduce its share capital or any capital redemption reserve fund.

        14.2 Subject to the provisions of the Statute, the Company may by Special Resolution change its name.

        14.3 Subject to the provisions of the Statute, the Board of Directors may change the location of the Company's registered office.

F-9


lawful action, the Board of Directors may provide that the Register shall be closed for transfers for a stated period.

        15.2 In lieu of or apart from closing the Register, the Board of Directors may fix in advance a date as the record date for any such determination of Members entitled to notice of or to vote at a general meeting of the Company; provided, however, that such record date shall not be more than 60 nor less than 10 days prior to such meeting. For the purpose of determining the Members entitled to receive payment of any dividend or other distribution or allotment of any rights of the Members entitled to exercise any rights in respect of any charge, change, conversion or exchange of shares, or for the purpose of any other lawful action, the Board of Directors may, at or within 60 days prior to the date of declaration of such dividend or other action, fix a subsequent date no later than the date of declaration as the record date for such determination.

        15.3 If the Register is not so closed and no record date is fixed for the determination of Members entitled to notice of or to vote at a general meeting of the Company, the date preceding the day on which notice of the meeting is given or if notice is waived, at the close of business on the day preceding the day on which the meeting is held shall be the record date for such determination of Members. When a determination for Members entitled to vote at any general meeting of the Company has been made as provided in this Article XV, such determination shall apply to any adjournment thereof; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

        15.4 If the Register is not so closed and no record date is fixed for the determination of Members entitled to receive payment of any dividend or other distribution or allotment of any rights of the Members entitled to exercise any rights in respect of any charge, change, conversion or exchange of shares, or for the purpose of any other lawful action (other than as specified in Article 15.3), the record date for determining the Members for any such purpose shall be the close of business on the day in which the Board of Directors adopts the resolution relating thereto.

The presiding officer of the meeting may refuse to transact any business at any meeting made without compliance with the foregoing procedure.

        (d)   Notwithstanding the provisions of Article 19.2, a Member also shall comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in Article 19.2.

A proxy need not be a Member. Each Member entitled to vote at a general meeting of the Company may authorize another person or persons to act for him by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy specifically provides for a longer period. If an instrument of proxy designates two or more persons to act as proxies, their acts with respect to voting shall have the following effect: (a) if only one proxy acts, his acts bind all; (b) if more than one proxy acts, the act of the majority binds all; and (c) if more than one acts and a majority do not agree on a particular issue, each proxy shall be entitled to vote in respect of the same portion of the shares as such proxy is of the proxies representing such shares.

        20.2    The instrument appointing a proxy shall be deposited at the principal executive offices of the Company or at such other place as is specified for that purpose in the notice convening the meeting no later than the time for holding the meeting, or adjourned meeting; provided that the presiding officer of the meeting may at his discretion direct that an instrument of proxy shall be deemed to have been duly deposited upon receipt of a facsimile transmission of the signed proxy, upon receipt of an electronic transmission of the proxy containing an electronic signature from a source determined by the presiding officer of the meeting to have been reliable or upon receipt of telex or cable confirmation from the appointor that the instrument of proxy duly signed is in the course of transmission to the Company. For the purposes of this Article 20.2, "electronic signature" means an electronic sound, symbol or process attached to or logically associated with an electronic record and executed or adopted by a person with intent to sign the electronic record.

        20.3    The instrument appointing a proxy may be in any usual or common form and may be expressed to be for a particular meeting or any adjournment thereof.

        20.4    A vote given in accordance with the term of an instrument of proxy shall be valid notwithstanding the previous death or insanity of the principal or revocation of the proxy or of the authority under which the proxy was executed, or the transfer of the share in respect of which the proxy is given provided that no notice in writing of such death, insanity, revocation or transfer as aforesaid shall have been received by the Company at its principal executive offices before the commencement of the general meeting, or adjourned meeting, at which it is sought to use the proxy.

The Board of Directors shall have the exclusive power and right to set the exact number of Directors within that range from time to time by resolution adopted by the vote of a majority of the whole Board of Directors.

        (b)   Except as set out in Article 21.1(f), the Directors shall be divided into three classes, designated by Class I, Class II and Class III.

At the 2009 annual general meeting of the Company, Class I Directors shall be elected for a term expiring at the 2012 annual general meeting of the Company. At the 2010 annual general meeting of the Company, Class II Directors shall be elected for a term expiring at the 2013 annual general meeting of the Company. At each annual general meeting of the Company, each class of Directors whose term shall then expire shall be elected to hold office for a three-year term and until the election of their respective successors in office or their earlier death, resignation or removal.

        (c)   If the number of Directors is decreased by resolution of the Board of Directors pursuant to this Article 21.1, in no case shall that decrease or shorten the term of any incumbent Director.

        (d)   Any newly created directorship resulting from an increase in the number of Directors and any other vacancy on the Board of Directors, however caused, may only be filled by a majority of the Directors then in office, although less than a quorum, or by a sole remaining Director. Any Director elected by the Board of Directors to fill a vacancy shall hold office until the annual general meeting of the Company for the year in which the term of the Director vacating office expires and until his successor shall have been elected. Any newly created directorship resulting from an increase in the number of Directors may be created in any Class of Directors that the Board of Directors may determine, and any Director elected to fill the newly created vacancy shall hold office until the term of office of such Class expires.

        (e)   One or more or all of the Directors may be removed only for "cause" by the affirmative vote of the holders of at least a majority of the issued shares generally entitled to vote, voting together as a single class, at a general meeting of the Company for which proper notice of the proposed removal has been given. As used in the preceding sentence, "cause" shall be limited to (i) action by the Director involving willful malfeasance, which conduct has a material adverse effect on the Company, or (ii) conviction of the Director of a felony. The Board of Directors shall not have any power to remove any Director.

        (f)    Notwithstanding the foregoing, whenever the holders of any one or more classes or series of shares in issue has the right, voting separately by class or series, to elect Directors at an annual general meeting or extraordinary general meeting of the Company, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the provisions of these Articles. Directors so elected shall not be divided into classes and shall be elected by such holders annually unless expressly provided otherwise by those provisions or resolutions. The aforesaid Directors and the

F-15



Directors appointed under Article 21.1 shall together constitute the Board of Directors from time to time.

        21.2    Each Director shall be entitled to receive as compensation for such Director's services as a Director or committee member or for attendance at meetings of the Board of Directors or committees, or both, such amounts (if any) as shall be fixed from time to time by the Board of Directors. Each Director shall be entitled to reimbursement for reasonable traveling expenses incurred by such Director in attending any such meeting.

        21.3    A Director may hold any other office (other than as an outside auditor of the Company) or place of profit under the Company in conjunction with his office of Director for such period and on such terms as to remuneration and otherwise as the Board of Directors may determine.

        21.4    A Director may act by himself or for his firm in a professional capacity for the Company (other than as an outside auditor of the Company), and he or his firm shall be entitled to remuneration for professional services as if he were not a Director; provided, however, that he has disclosed his interest in the transaction at the first meeting held to consider the transaction or as soon thereafter as he becomes interested in the transaction.

        21.5    No membership qualifications for Directors shall be required.

        21.6    A Director may be or become a director or other officer of or otherwise interested in any company promoted by the Company or in which the Company may be interested as shareholder, member or otherwise, and no such Director shall be accountable to the Company for any remuneration or other benefits received by him as a director or officer of, or from his interest in, such other company.

        21.7    No person shall be disqualified from the office of Director or prevented by such office from contracting with the Company, either as vendor, purchaser or otherwise, nor shall any such contract or any contract or transaction entered into by or on behalf of the Company in which any Director shall be in any way interested or be liable to be avoided, nor shall any Director so contracting or being so interested be liable to account to the Company for any profit realized by any such contract or transaction by reason of such Director holding office or of the fiduciary relation thereby established; provided, however, that he has disclosed his interest in the transaction at the first meeting held to consider the transaction or as soon thereafter as he becomes interested in the transaction. A Director shall be at liberty to vote in respect of any contract or transaction in which he is so interested as aforesaid; provided, however, that the nature of the interest of any Director in any such contract or transaction shall be disclosed by him at or prior to its consideration and any vote thereon.

        21.8    A general notice that a Director is a member of any specified firm or company and is to be regarded as interested in any transaction with such firm or company shall be sufficient disclosure under Article 21.7 and after such general notice it shall not be necessary to give special notice relating to any particular transaction.

        21.9    The Directors may exercise all the powers of the Company to provide pensions or other retirement or superannuation benefits and to provide death or disability benefits or other allowances or gratuities (by insurance or otherwise) for a person who is or has at any time been a Director of (a) the Company, (b) a company which is or was an affiliate of the Company, or (c) a predecessor in business of the Company or of an affiliate of the Company (or, in each case, for any member of his family, including a spouse or former spouse, or a person who is or was dependent on him). For this purpose, the Directors may establish, maintain, subscribe and contribute to any scheme, plan, trust or fund and pay premiums thereon. The Directors may arrange for this to be done by the Company alone or in conjunction with another person.

In such event the Board of Directors shall do all acts and things required to give effect to such capitalization, with full power to the Board of Directors to make such provisions as it thinks fit for the case of shares becoming distributable in fractions (including provisions whereby the benefit of fractional entitlements accrue to the Company rather than to the Members concerned).

The liquidator may with the sanction of a Special Resolution distribute, in kind, to the holders of the Ordinary Shares remaining assets of the Company or may, without the need of any such sanction sell, transfer or otherwise dispose of all or any part of such remaining assets to any other person, corporation, trust or entity and receive payment therefor in cash, shares or obligations of such other person, corporation, trust or entity or any combination thereof, and may sell all or any part of the consideration so received, and may distribute the consideration received or any balance or proceeds thereof to holders of the Ordinary Shares. The liquidator may, with the like sanction, vest the whole or any part of such assets in trustees upon such trusts for the benefit of the contributories as the liquidator, with the like sanction shall think fit, but so that no Member shall be compelled to accept any shares or other securities whereon there is any liability.
