5 ITEM 4. DESCRIPTION OF SECURITIES. Not Applicable. ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL. Not Applicable. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 34.1 of Transocean Sedco Forex's articles of association provides that: No directors of Transocean Sedco Forex will be personally liable to Transocean Sedco Forex or, if any, its members for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to Transocean Sedco Forex or, if any, to its members, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law or (iii) for any transaction from which the director derived an improper personal benefit. Transocean Sedco Forex will indemnify, to the fullest extent permitted by the laws of the Cayman Islands as from time to time in effect, if any, any person who was or is a party or is threatened to be made a party to, or otherwise requires representation by counsel in connection with, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not an action by or in the right of Transocean Sedco Forex) by reason of the fact that he is or was a director or officer of Transocean Sedco Forex, or, while serving as a director or officer of Transocean Sedco Forex, is or was serving at the request of Transocean Sedco Forex, as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity. The right to indemnification conferred by Section 34.1 also includes the right of such persons to be paid in advance by Transocean Sedco Forex for their expenses to the fullest extent permitted by the laws of the Cayman Islands as from time to time in effect. Unless otherwise determined by the Transocean Sedco Forex board of directors, Transocean Sedco Forex will indemnify to the fullest extent permitted by the laws of the Cayman Islands as from time to time in effect, if any, any person who was or is a party or is threatened to be made a party to, or otherwise requires representation by counsel in connection with, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not an action by or in the right of Transocean Sedco Forex), by reason of the fact that he is or was an employee (other than an officer) or agent of Transocean Sedco Forex, or is or was serving at the request of Transocean Sedco Forex as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity. The rights and authority conferred by Section 34.1 are not exclusive of any other right that any person has or hereafter acquires under any law, provision of Transocean Sedco Forex's articles of association or memorandum of association, agreement, vote of members of Transocean Sedco Forex or of the board of directors of Transocean Sedco Forex or otherwise. Transocean Sedco Forex also has directors and officers liability insurance that would indemnify its directors and officers against damages arising out of certain kinds of claims that might be made against them based on their negligent acts or omissions while acting in their capacity as such. The Merger Agreement provides that, following the Merger, Transocean Sedco Forex will indemnify, defend and hold harmless, to the fullest extent permitted under applicable law, (1) each person who is, or has been at II-2

6 any time prior to the effective time of the merger, an officer or director of R&B Falcon or any of its subsidiaries or divisions and (2) each person who served as a director, officer, trustee or fiduciary of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise at the request of R&B Falcon 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 that arises out of or pertains to actual or alleged acts or omissions by them in the capacities set forth in (1) and (2) above.

ITEM 9. UNDERTAKINGS. (1) The undersigned Registrant hereby undertakes: (a) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a) (3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement. II-5

9 (b) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (d) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (e) That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this Registration Statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form. (f) That every prospectus (i) that is filed pursuant to paragraph (e) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a) (3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as part of an amendment to the Registration Statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (g) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10 (b), 11, or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request. (h) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the Registration Statement when it became effective. (2) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such of such issue.

Box 265GT, Walker House, Mary Street, George Town Grand Cayman, Cayman Islands Tel: (345) 949-0100 Fax: (345) 949-7886 Email: walker@candw.ky TRANSOCEAN SEDCO FOREX INC. 4 GREENWAY PLAZA HOUSTON, TX 77046 January 31, 2001 Gentlemen, VALIDITY OF ISSUE OF ORDINARY SHARES ISSUABLE UPON THE EXERCISE OF OPTIONS ASSUMED BY TRANSOCEAN SEDCO FOREX INC., A CAYMAN ISLANDS EXEMPTED COMPANY. We have acted as special Cayman Islands counsel to Transocean Sedco Forex Inc. a Cayman Islands exempted company (TRANSOCEAN) in connection with the merger with R&B Falcon Corporation a Delaware corporation (R&B FALCON) pursuant to which R&B Falcon merged with an indirect wholly owned subsidiary of Transocean on January 31, 2001 (the MERGER). The Merger was effected pursuant to the terms and provisions of that certain Agreement and Plan of Merger dated as of August 19, 2000 among Transocean, Transocean Holdings Inc., TSF Delaware Inc. and R&B Falcon (the MERGER AGREEMENT) which is described in the proxy statement/prospectus (the PROXY STATEMENT/PROSPECTUS) and filed as part of that certain Registration Statement on Form S-4 filed by Transocean with the United States Securities and Exchange Commission (the SEC) on September 22, 2000 (the REGISTRATION STATEMENT). Pursuant to the Merger Agreement and as described in the Proxy Statement/Prospectus, R&B Falcon common shares were converted into the right to receive ordinary shares of a par or nominal value of US$.01 per share of Transocean upon completion of the Merger and each R&B Falcon option to purchase R&B Falcon common shares under R&B Falcon's stock option plans (the PLANS) was assumed by Transocean and became an option to purchase ordinary shares of Transocean (the OPTION SHARES). For the purposes of giving this opinion, we have examined the documents listed in Schedule 1. In giving this opinion we have relied upon the assumptions set out in Schedule 2 hereto, which we have not independently verified. We are Attorneys-at-Law in the Cayman Islands and express no opinion as to any laws other than the laws of the Cayman Islands in force and as interpreted at the date hereof. Based upon the foregoing examinations, the assumptions set out in Schedule 2 and upon such searches as we have conducted and having regard to legal considerations which we deem relevant, we are of the opinion that -1-

2 under the laws of the Cayman Islands: 1. Transocean is a company duly incorporated and validly existing and, based solely on the certificate of good standing issued by the Cayman Islands Registrar of Companies and referred to in Schedule 1, Transocean is in good standing under the laws of the Cayman Islands. 2. The Option Shares subject to original issuance by Transocean have been duly authorised and when and to the extent issued and sold from time to time in accordance with the terms of the Plans and upon payment thereof as provided in the Plans, such Option Shares will be validly issued, fully paid and non-assessable. This opinion is limited to the matters referred to herein and shall not be construed as extending to any other matter or document not referred to herein. This opinion is given solely for your benefit, the benefit of your legal advisers acting in that capacity in relation to this transaction and the shareholders of Transocean and may not be relied upon by any other person without our prior written consent. This opinion is governed by and shall be construed in accordance with the laws of the Cayman Islands. Yours faithfully, /s/ WALKERS WALKERS -2-

3 SCHEDULE 1 LIST OF DOCUMENTS EXAMINED 1. The Memorandum and Articles of Association of Transocean and certificate of good standing dated 29 January 2001 issued by the Cayman Islands Registrar of Companies. 2. The Resolutions adopted by the Board of Directors of Transocean pursuant to their meeting of August 18, 2000. 3. The Resolutions adopted by the shareholders of Transocean at an extraordinary general meeting of Transocean on 12 December 2000. 4. The proxy statement/prospectus contained in the Registration Statement filed with the United States Securities and Exchange Commission on September 22, 2000. 5. Such other documents as we have considered necessary for the purposes of rendering this opinion. The documents at paragraphs 2 and 3 above are referred to in this opinion as the "RESOLUTIONS". -3-

4 SCHEDULE 2 ASSUMPTIONS The opinions hereinbefore given are based upon the following assumptions insofar as each such assumption may relate to the opinions given: 1. All original documents are authentic, that all signatures and seals are genuine, that all documents purporting to be sealed have been so sealed and that all copies conform to their originals. 2. The Minute Book of Transocean supplied to us on the date of this opinion by Transocean's registered office contains a complete record of the business transacted by it. 3. The corporate records of Transocean supplied to us on the date of this opinion by Transocean's registered office constitute its complete corporate records and that all matters required by law to be recorded therein are so recorded. 4. From the date of the Resolutions, no corporate or other action has been taken by Transocean to amend, alter or repeal the Resolutions and no corporate or other action has been taken by Transocean in connection with the Merger except as contemplated by the Registration Statement. 5. There are no provisions of the laws of any jurisdiction outside the Cayman Islands which would be contravened by Transocean's assumption of the Plans and that, in so far as any obligation expressed to be incurred under the Plans is to be performed in or is otherwise subject to the laws of any jurisdiction outside the Cayman Islands, its performance will not be illegal by virtue of the laws of that jurisdiction. 6. The choice of the laws selected to govern the Plans has been made in good faith and will be regarded as a valid and binding selection which will be upheld in the courts of that jurisdiction and all other relevant jurisdictions (other than the Cayman Islands). 7. All authorisations, approvals, consents, licences and exemptions required by and all filings and other requirements of each of the parties to the Plans outside the Cayman Islands to ensure the legality, validity and enforceability of the Plans have been or will be duly obtained, made or fulfilled and are and will remain in full force and effect and that any conditions to which they are subject have been satisfied. 8. On the date of any disposition or settlement of property effected by the Plans is made in good faith and for valuable consideration and at the time of each disposition of property by Transocean pursuant to the Plans Transocean will be able to pay its debts as they become due from its own moneys. -4-
