Items 1, 2, 4, 10 and 11 of the Schedule TO are hereby amended to read in their entirety as follows: ITEM 1. Summary Term Sheet. The following are answers to some of the questions that you may have about our offer to repurchase your debentures as described in this document. We refer to this offer as the "Offer." To understand the Offer fully and for a more complete description of the terms of the Offer, we urge you to carefully read the remainder of this document and the accompanying company notice because the information in this summary is not complete and the remainder of this document and the notice contain additional important information. - WHO IS OFFERING TO REPURCHASE MY DEBENTURES? We are Transocean Inc., a Cayman Islands company, and we are offering to repurchase all outstanding Zero Coupon Convertible Debentures Due May 24, 2020 issued by us on May 24, 2000. We issued the debentures under an Indenture, dated as of April 15, 1997, as supplemented, between us and The Bank of New York (as successor trustee to Chase Bank of Texas, National Association), as trustee. As of April 24, 2003, there was $865,000,000 aggregate principal amount of debentures outstanding. - WHY ARE YOU MAKING THE OFFER? We are required to make the Offer under the terms of the debentures and the indenture. - HOW MUCH ARE YOU OFFERING TO PAY? Each holder of the debentures may require us to repurchase its debentures at a repurchase price of $628.57 per $1,000 principal amount. - WHAT IS THE FORM OF PAYMENT? Under the terms of the debentures, we may pay the repurchase price in cash, ordinary shares or any combination thereof. We have determined that, if any holders of debentures require us to repurchase any debentures, we will pay the repurchase price in cash. - ARE THE DEBENTURES CONVERTIBLE INTO ORDINARY SHARES? Yes. Each debenture is convertible at any time, at the option of the holder, into Transocean's ordinary shares at a conversion rate of 8.1566 ordinary shares per $1,000 principal amount. This conversion rate is subject to adjustment in certain events. - HOW CAN I DETERMINE THE MARKET VALUE OF THE DEBENTURES? There is no established reporting system or market for trading in the debentures. To the extent that the debentures are traded, prices of the debentures may fluctuate widely depending on trading volume, the balance between buy and sell orders, prevailing interest rates, the market price of our ordinary shares, our business, financial condition and operating results and the market for similar securities. Holders are urged to obtain current market quotations to the extent available for the debentures prior to making any decision with respect to the Offer. - WHAT DOES YOUR BOARD OF DIRECTORS THINK OF THE OFFER? Although our board of directors has approved the terms of the Offer included in the indenture, the board has not made any recommendation as to whether you should accept the Offer and surrender your debentures for 1 repurchase. You must make your own decision whether to accept the Offer and surrender your debentures for repurchase and, if so, the number of debentures you elect to have repurchased. - WHEN DOES THE OFFER EXPIRE? The Offer expires at 10:00 a.m., New York City time, on May 27, 2003. Although the indenture provides that we are required to repurchase debentures if the holder of the debentures delivers notice before the close of business on May 24, 2003, because that date falls on a Saturday, we have extended the deadline for accepting the Offer to allow holders additional time to accept the Offer. For purposes of the indenture, if you accept the Offer and do not withdraw your acceptance before the expiration of the Offer, we will treat your acceptance and the repurchase as having been made as of May 24, 2003. We do not expect to otherwise extend the period you have to accept the Offer. However, we reserve the right, in our sole discretion, to provide a subsequent repurchase period of between three and 20 business days to allow additional time for holders to accept the Offer. If a subsequent repurchase period is provided, all repurchase notices delivered and debentures surrendered prior to the initial expiration of the Offer and not withdrawn will be accepted and promptly paid, and we will make a public announcement of the subsequent repurchase period no later than 9:00 a.m., New York City time, on May 28, 2003. Unless otherwise provided in the announcement of the subsequent repurchase period, all repurchase notices delivered and debentures surrendered during the subsequent repurchase period will be promptly accepted and paid. Unless otherwise provided in the announcement of the subsequent repurchase period, holders will not have the right to withdraw repurchase notices delivered and debentures surrendered during the subsequent repurchase period. - WHAT ARE THE CONDITIONS TO YOUR REPURCHASE OF THE DEBENTURES? As long as our repurchase of validly surrendered debentures is not unlawful, that repurchase will not be subject to any other conditions. - HOW DO I ACCEPT THE OFFER? You may accept the Offer prior to its expiration as follows: - Holders who are participants in The Depository Trust Company should accept the Offer electronically through DTC's Automated Tenders over the Participant Terminal System, subject to the terms and procedures of that system. Holders accepting the Offer through DTC need not submit a physical repurchase notice to the paying agent if those holders comply with DTC's procedures. - Holders whose debentures are held by a broker, dealer, commercial bank, trust company or other nominee must contact that nominee if those holders desire to accept the Offer and instruct that nominee to accept the Offer on the holders' behalf. - Holders whose debentures are held directly and not through DTC or a nominee must deliver a written notice of repurchase, in the form attached to the company notice delivered with this document, to The Bank of New York, as paying agent. - HOW DO I SURRENDER MY DEBENTURES? After validly accepting the Offer, you may surrender your debentures for repurchase pursuant to the Offer by delivering the required documents to The Bank of New York, as paying agent, prior to, on or after May 24, 2003, as follows: - Holders who are participants in The Depository Trust Company should surrender their debentures electronically through DTC's Automated Tenders over the Participant Terminal System, subject to the terms and procedures of that system. 2 - Holders whose debentures are held by a broker, dealer, commercial bank, trust company or other nominee must contact that nominee if those holders desire to surrender their debentures and instruct that nominee to surrender the debentures on the holders' behalf. - Holders whose debentures are held directly and not through DTC or a nominee must surrender their debentures together with all necessary endorsements to The Bank of New York, as paying agent. You will not receive payment for your debentures until you surrender them to the paying agent. DEBENTURES AND THE REPURCHASE NOTICE MUST BE DELIVERED TO THE PAYING AGENT TO COLLECT PAYMENT. DELIVERY OF DOCUMENTS TO DTC OR TRANSOCEAN DOES NOT CONSTITUTE DELIVERY TO THE PAYING AGENT. - IF I ACCEPT THE OFFER, WHEN WILL I RECEIVE PAYMENT FOR MY DEBENTURES? We will forward to the paying agent, prior to 11:00 a.m., New York City time, on May 27, 2003, the appropriate amount of cash required to pay the total repurchase price for the debentures to be repurchased pursuant to the Offer, and the paying agent will promptly distribute the cash to the holders, subject to receipt of the surrendered debentures. - UNTIL WHAT TIME CAN I WITHDRAW A PREVIOUSLY DELIVERED REPURCHASE NOTICE? You can withdraw a previously delivered repurchase notice at any time until expiration of the Offer at 10:00 a.m., New York City time, on May 27, 2003. - HOW DO I WITHDRAW A PREVIOUSLY DELIVERED REPURCHASE NOTICE AND ANY PREVIOUSLY SURRENDERED DEBENTURES? You may withdraw a previously delivered repurchase notice and any previously surrendered debentures as follows: - Holders who are participants in The Depository Trust Company should withdraw a previously delivered repurchase notice and any previously surrendered debentures electronically through DTC's Automated Tenders over the Participant Terminal System, subject to the terms and procedures of that system. Holders withdrawing a previously delivered repurchase notice and any previously surrendered debentures through DTC need not submit a written notice of withdrawal to the paying agent if those holders comply with DTC's procedures. - Holders whose debentures are held by a broker, dealer, commercial bank, trust company or other nominee must contact that nominee if those holders desire to withdraw a previously delivered repurchase notice and any previously surrendered debentures and instruct that nominee to withdraw a previously delivered repurchase notice and any previously surrendered debentures on the holders' behalf. - Holders whose debentures are held directly and not through DTC or a nominee must deliver a written notice of withdrawal to The Bank of New York, as paying agent, stating the certificate number of the debentures being withdrawn, the principal amount of the debentures being withdrawn and the principal amount, if any, of the debentures that remain subject to the previously delivered repurchase notice and which has been or will be delivered for repurchase by Transocean. 3 - DO I NEED TO DO ANYTHING IF I DO NOT WISH TO ACCEPT THE OFFER AND SURRENDER MY DEBENTURES FOR REPURCHASE? No. If you do not deliver a properly completed and duly executed repurchase notice to the paying agent before the expiration of the Offer, we will not repurchase your debentures and such debentures will remain outstanding subject to their existing terms. - IF I CHOOSE TO ACCEPT THE OFFER, DO I HAVE TO SURRENDER ALL OF MY DEBENTURES FOR REPURCHASE? No. You may accept the Offer and surrender all of your debentures or a portion of your debentures for repurchase. If you wish to accept the Offer and surrender a portion of your debentures for repurchase, however, you must surrender your debentures in a principal amount of $1,000 or an integral multiple of $1,000. - IF I DO NOT ACCEPT THE OFFER AND SURRENDER MY DEBENTURES FOR REPURCHASE, WILL I CONTINUE TO BE ABLE TO EXERCISE MY CONVERSION RIGHTS? Yes. If you do not accept the Offer and surrender your debentures for repurchase, your conversion rights will not be affected. - IF I AM A U.S. RESIDENT FOR U.S. FEDERAL INCOME TAX PURPOSES, WILL I HAVE TO PAY TAXES IF I ACCEPT THE OFFER AND SURRENDER MY DEBENTURES FOR REPURCHASE PURSUANT TO THE OFFER? The receipt of cash in exchange for debentures pursuant to the Offer will be a taxable transaction for U.S. federal income tax purposes. You should consult with your tax advisor regarding the actual tax consequences to you. - WHO IS THE PAYING AGENT?

This conversion rate is subject to adjustment in 4 certain events. Transocean's ordinary shares are listed on the New York Stock Exchange under the symbol "RIG."

We urge you to obtain current market information for the debentures, to the extent available, and the ordinary shares before making any decision to surrender your debentures pursuant to the Offer. ITEM 4. TERMS OF THE TRANSACTION. (a) Material Terms. GENERAL The securities subject to this Schedule TO and to the transaction described in this document are Transocean's Zero Coupon Convertible Debentures Due May 24, 2020. See response to paragraph (b) of Item 2 above. Transocean issued the debentures under an Indenture dated as of April 15, 1997 between Transocean and The Bank of New York (as successor trustee to Chase Bank of Texas, National Association), as trustee, as amended and supplemented by the First Supplemental Indenture thereto dated as of April 15, 1997, the Second Supplemental Indenture thereto dated as of May 14, 1999, the Third Supplemental Indenture thereto dated as of May 24, 2000 and the Fourth Supplemental Indenture thereto dated May 11, 2001. The description of the debentures and the indenture set forth under the caption "Description of Debentures" in Transocean's prospectus supplement dated May 19, 2000 to the prospectus dated November 12, 1999 and under the caption "Description of Debt Securities" in that prospectus is incorporated by reference in this Schedule TO. Under the indenture, each holder of the debentures may require Transocean to repurchase that holder's debentures as of May 24, 2003 at a repurchase price of $628.57 per $1,000 principal amount. Transocean will pay the repurchase price in cash with respect to any and all debentures validly surrendered for repurchase and not withdrawn. Transocean will accept debentures surrendered for repurchase only in principal amounts equal to $1,000 or integral multiples thereof. Original issue discount on the debentures validly surrendered for repurchase and not withdrawn will cease to accrue immediately after Transocean deposits with the paying agent cash sufficient to pay the total repurchase price for the debentures to be repurchased pursuant to the Offer. The repurchase price is based solely on the requirements of the indenture and the debentures and bears no relationship to the market price of the debentures or of Transocean's ordinary shares. Accordingly, the repurchase price may be significantly higher or lower than the current market price of the debentures. Holders of debentures are urged to obtain the best available information as to potential current market prices of the debentures, to the 5 extent available, and Transocean's ordinary shares before making a decision whether to accept the Offer and surrender their debentures for repurchase. If any debentures remain outstanding following expiration of the Offer, Transocean will become obligated to repurchase the debentures, at the option of the holders, in whole or in part, on May 24, 2008 and 2013 at repurchase prices of $720.55 and $825.98 per $1,000 principal amount respectively. Transocean will have the option to pay the repurchase price in cash, ordinary shares or a combination thereof. On or after May 24, 2003, Transocean may redeem any debentures that remain outstanding, in whole or in part, for cash at a price equal to the issue price plus accrued original issue discount to the redemption date. EXPIRATION OF THE OFFER The Offer expires at 10:00 a.m., New York City time, on May 27, 2003. Although the indenture provides that Transocean is required to repurchase debentures if the holder of the debentures delivers notice before the close of business on May 24, 2003, because that date falls on a Saturday, Transocean has extended the deadline for accepting the Offer to allow holders additional time to accept the Offer. For purposes of the indenture, if a holder accepts the Offer and does not withdraw his or her acceptance before the expiration of the Offer, Transocean will treat the holder's acceptance and the repurchase as having been made as of May 24, 2003. If holders do not accept the Offer on or before the expiration of the Offer and validly surrender their debentures, their debentures will remain outstanding subject to the existing terms of the debentures. Transocean does not expect to otherwise extend the period holders of debentures have to accept the Offer. However, we reserve the right, in our sole discretion, to provide a subsequent repurchase period of between three and 20 business days to allow additional time for holders to accept the Offer. If a subsequent repurchase period is provided, all repurchase notices and debentures surrendered prior to the initial expiration of the Offer and not withdrawn will be accepted and promptly paid, and we will make a public announcement of the subsequent repurchase period no later than 9:00 a.m., New York City time, on May 28, 2003. Unless otherwise provided in the announcement of the subsequent repurchase period, all repurchase notices delivered and debentures surrendered during the subsequent repurchase period will be promptly accepted and paid. Unless otherwise provided in the announcement of the subsequent repurchase period, holders will not have the right to withdraw repurchase notices delivered and debentures surrendered during the subsequent repurchase period. PROCEDURES FOR ACCEPTING THE OFFER Holders may accept the Offer prior to its expiration as follows: - Holders who are participants in The Depository Trust Company should accept the Offer electronically through DTC's Automated Tenders over the Participant Terminal System ("PTS"), subject to the terms and procedures of that system. Holders accepting the Offer through DTC need not submit a physical repurchase notice to the paying agent if those holders comply with DTC's procedures. - Holders whose debentures are held by a broker, dealer, commercial bank, trust company or other nominee must contact that nominee if those holders desire to accept the Offer and instruct that nominee to accept the Offer on the holders' behalf. - Holders whose debentures are held directly and not through DTC or a nominee must deliver a written notice of repurchase, in the form attached to the company notice delivered with this document, to The Bank of New York, as paying agent. The indenture requires that the repurchase notice contain: - the certificate number of the debentures being delivered for repurchase; 6 - the portion of the principal amount at maturity of the debentures to be repurchased, which portion must be in principal amounts at maturity of $1,000 or an integral multiple thereof; and - a statement that such debentures are to be repurchased as of May 24, 2003 pursuant to the terms and conditions specified in the indenture and the debentures under the heading "Repurchase by the Company at the Option of the Holder." Delivery of the repurchase notice will be deemed made only when actually received by the paying agent. The date of any postmark or other indication of when a repurchase notice was sent will not be taken into account in determining whether such materials were timely received. If such delivery is by mail, we suggest that holders use properly insured, registered mail with return receipt requested, and that the holders mail the repurchase notice sufficiently in advance of expiration of the Offer to permit delivery to the paying agent prior to the expiration of the Offer. In delivering a repurchase notice through PTS, the electronic instructions sent to DTC by the holder, and transmitted by DTC to the paying agent, will acknowledge, on behalf of DTC and the holder, receipt by the holder of this document and the company notice delivered with this document. PROCEDURES FOR SURRENDERING DEBENTURES After validly accepting the Offer, a holder may surrender his or her debentures by delivering the required documents to the paying agent prior to, on or after May 24, 2003. Debentures surrendered for repurchase must be surrendered in principal amounts of $1,000 or an integral multiple thereof. The method of delivery of debentures, including delivery through DTC and acceptance through PTS, is at the election and risk of the person surrendering such debentures and, except as expressly otherwise provided in the repurchase notice, delivery will be deemed made only when actually received by the paying agent. A holder will not receive any payment until his or her debentures to be repurchased pursuant to the Offer are surrendered to the paying agent. After validly accepting the Offer, a holder whose debentures are held by a broker, dealer, commercial bank, trust company or other nominee must contact such nominee if such holder desires to surrender his or her debentures and instruct such nominee to surrender the debentures for repurchase on the holder's behalf. A holder who is a DTC participant may elect to surrender to Transocean his or her beneficial interest in the debentures by delivering to the paying agent's account at DTC through DTC's book-entry system his or her beneficial interest in the debentures. Holders whose debentures are held directly and not through DTC or a nominee must surrender their debentures together with all necessary endorsements to The Bank of New York, as paying agent. DEBENTURES AND THE REPURCHASE NOTICE MUST BE DELIVERED TO THE PAYING AGENT TO COLLECT PAYMENT. DELIVERY OF DOCUMENTS TO DTC OR TRANSOCEAN DOES NOT CONSTITUTE DELIVERY TO THE PAYING AGENT. WITHDRAWAL PROCEDURES A previously delivered repurchase notice and any debentures previously surrendered for repurchase may be withdrawn at any time prior to the expiration of the Offer at 10:00 a.m., New York City time, on May 27, 2003. Holders may withdraw a previously delivered repurchase notice and any debentures previously surrendered for repurchase as follows: - Holders who are participants in The Depository Trust Company should withdraw a previously delivered repurchase notice and any previously surrendered debentures electronically through DTC's Automated Tenders over the Participant Terminal System, subject to the terms and procedures of that system. Holders withdrawing a previously delivered repurchase notice and any previously surrendered debentures through DTC need not submit a written notice of withdrawal to the paying agent if those holders comply with DTC's procedures. 7 - Holders whose debentures are held by a broker, dealer, commercial bank, trust company or other nominee must contact that nominee if those holders desire to withdraw a previously delivered repurchase notice and any previously surrendered debentures and instruct that nominee to withdraw a previously delivered repurchase notice and any previously surrendered debentures on the holders' behalf. - Holders whose debentures are held directly and not through DTC or a nominee must deliver a written notice of withdrawal to The Bank of New York, as paying agent, stating the certificate number of the debentures being withdrawn, the principal amount of the debentures being withdrawn and the principal amount, if any, of the debentures that remain subject to the previously delivered repurchase notice and which has been or will be delivered for repurchase by Transocean. A previously delivered repurchase notice and debentures surrendered for repurchase that are properly withdrawn will be deemed not validly surrendered for purposes of the Offer. A repurchase notice and any debentures withdrawn from the Offer may be resurrendered by following the surrender procedures described above. PAYMENT OF REPURCHASE PRICE Each holder of a beneficial interest in the validly surrendered debentures required to be repurchased pursuant to the Offer, will receive the repurchase price promptly after the expiration of the Offer, subject to receipt of the surrendered debentures. U.S. FEDERAL INCOME TAX CONSIDERATIONS The following discussion, which is for general information only, is a summary of the material U.S. federal income tax considerations relating to the surrender of debentures for repurchase pursuant to the Offer. This discussion does not purport to be a complete analysis of all potential tax effects of the Offer. This summary is based upon laws, regulations, rulings and decisions currently in effect, all of which are subject to change or differing interpretations at any time, possibly with retroactive effect. Moreover, this summary applies only to holders who hold debentures as "capital assets" within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code"), and does not purport to deal with persons in special tax situations, such as financial institutions, insurance companies, regulated investment companies, tax exempt investors, dealers in securities and currencies, U.S. expatriates, persons holding debentures as a position in a "straddle," "hedge," "conversion" or other integrated transaction for tax purposes, or U.S. Holders (as defined below) whose functional currency is not the U.S. dollar. Further, this discussion does not address the consequences under U.S. federal estate or gift tax laws or the laws of any U.S. state or locality or any non-U.S. jurisdiction. For purposes of this discussion, a "U.S. Holder" means a beneficial owner of debentures that is, for U.S. federal income tax purposes: a citizen or resident of the United States; a corporation (or other entity that has elected to be treated as a corporation) created or organized in or under the laws of the United States or any political subdivision thereof; an estate the income of which is subject to U.S. federal income tax regardless of its source; a trust if a court within the United States is able to exercise primary jurisdiction over its administration and one or more U.S. persons have authority to control all of its substantial decisions; and certain electing trusts that were in existence and treated as U.S. trusts on August 20, 1996. As used herein, the term "non-U.S. Holder" means a beneficial owner of debentures, other than a partnership, that is not a U.S. Holder as defined above. The tax treatment of a partnership that holds debentures will generally depend on the status of the partners and the activities of the partnership. Holders that are partnerships should consult their own tax advisors about the U.S. federal income tax consequences of surrendering debentures pursuant to the Offer. Sale of Debentures Pursuant to the Offer. A U.S. Holder who receives cash in exchange for debentures pursuant to the Offer will recognize taxable gain or loss equal to the difference between (a) the amount of cash received and (b) the holder's adjusted tax basis in the debentures surrendered. A U.S. Holder's adjusted tax basis in the debentures will generally equal the U.S. Holder's cost of the debentures increased by any original issue discount that was previously included in income, or will be included in income this year, by such holder with respect to such debentures. Subject to the market discount rules discussed below, such gain or loss generally will be capital gain or loss, and will be 8 long-term capital gain or loss if the U.S. Holder held the debentures for more than one year. The deductibility of capital losses is subject to limitations. A U.S. Holder who acquired debentures at a market discount generally will be required to treat any gain recognized upon the repurchase of its debentures pursuant to the Offer as ordinary income rather than capital gain to the extent of the accrued market discount, unless the U.S. Holder elected to include market discount in income as it accrued. Subject to a de minimis exception, "market discount" generally equals the excess of the "adjusted issue price" (the sum of the issue price of the debentures and the aggregate amount of original issue discount which accrued on the debentures prior to the time acquired by the U.S. Holder) over the U.S. Holder's initial tax basis in the debentures. A non-U.S. Holder who receives cash in exchange for debentures pursuant to the Offer generally will not be subject to U.S. federal income tax on any gain recognized, unless (a) the gain is effectively connected with the conduct by such non-U.S. Holder of a trade or business, or, in the case of a treaty resident, is attributable to a permanent establishment or a fixed base, in the United States, or (b) such non-U.S. Holder is an individual who is present in the U.S. for 183 days or more in the taxable year of disposition and certain other conditions are met, in which case the gain will be taxable in the same manner as described above with respect to U.S. Holders. Backup Withholding. Under the backup withholding provisions of the Code, a U.S. Holder who surrenders debentures for repurchase will generally be subject to backup withholding at the rate of 30% of any gross payment if such holder fails to provide a certified Taxpayer Identification Number (Employer Identification Number or Social Security Number). A U.S. Holder who provides a certified Taxpayer Identification Number may nevertheless be subject to backup withholding on the portion of the payment representing original issue discount accruing this year, if Transocean has been notified by the Internal Revenue Service that such holder is currently subject to backup withholding as a result of a failure to report all interest or dividends or if such holder fails to certify to Transocean that such holder has not been so notified. U.S. Holders electing to surrender debentures should complete a Substitute Form W-9 and attach it to the debentures being surrendered. If you are a U.S. Holder exempt from backup withholding under the Code, please provide your Taxpayer Identification Number and so indicate in Part 2 of the Substitute Form W-9. If a non-U.S. Holder holds debentures through the non-U.S. office of a non-U.S. related broker or financial institution, backup withholding and information reporting generally will not be required. Information reporting, and possibly backup withholding, may apply if the debentures are held by a non-U.S. Holder through a U.S. broker or financial institution or the U.S. office of a non-U.S. broker or financial institution and the non-U.S. Holder fails to provide appropriate information (on Form W-8BEN or other applicable form). Non-U.S. Holders should consult their tax advisors with respect to the application of U.S. information reporting and backup withholding rules to the disposition of debentures pursuant to the Offer. ALL DESCRIPTIONS OF TAX CONSIDERATIONS ARE FOR HOLDERS' GUIDANCE ONLY AND ARE NOT TAX ADVICE. TRANSOCEAN RECOMMENDS THAT HOLDERS CONSULT WITH THEIR TAX AND FINANCIAL ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES OF SURRENDERING DEBENTURES FOR REPURCHASE, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL AND NON-U.S. TAX LAWS, BEFORE SURRENDERING THEIR DEBENTURES FOR REPURCHASE. REPURCHASES OF DEBENTURES BY TRANSOCEAN AND ITS AFFILIATES Each of Transocean and its affiliates are prohibited under applicable federal securities laws from purchasing debentures (or the right to repurchase debentures) other than through the Offer until at least the tenth business day after the repurchase date. Following that time, if any debentures remain outstanding, Transocean and its affiliates may repurchase debentures in the open market, in private transactions, through a subsequent tender offer or otherwise, any of which may be consummated at prices higher or lower than the repurchase price to be paid pursuant to the Offer. Any decision to repurchase debentures after the expiration of the Offer, if any, will depend upon many factors, including the market price of the debentures, the amount of debentures surrendered for repurchase pursuant to the Offer, the market price of Transocean's ordinary shares, Transocean's business and financial position and general economic and market conditions. 9 REPURCHASES OF OTHER DEBT SECURITIES BY TRANSOCEAN AND ITS AFFILIATES Prior to or after expiration of the Offer, Transocean plans to repurchase notes with aggregate principal amount outstanding of approximately $50 million relating to project financing for the construction of the Deepwater Nautilus. Prior to or after expiration of the Offer, Transocean and its affiliates may repurchase debt securities other than the debentures and such notes in the open market, in private transactions, through a tender offer or otherwise. Any decision to repurchase such debt securities, if any, and the price paid in such transaction will depend upon many factors, including the market price of such debt securities, the market price of Transocean's ordinary shares, Transocean's business and financial position and general economic and market conditions. DIVESTITURE OF GULF OF MEXICO SHALLOW AND INLAND WATER BUSINESS In December 2002, Transocean's subsidiary, TODCO, filed a registration statement with the Securities and Exchange Commission relating to Transocean's previously announced initial public offering of its Gulf of Mexico Shallow and Inland Water business. Transocean expects to separate this business and establish TODCO as a publicly traded company. Transocean is proceeding to reorganize TODCO as the entity that owns that business in preparation for the offering. Transocean plans to transfer assets not used in this business from TODCO to its other subsidiaries. Transocean expects to complete the initial public offering when market conditions warrant, subject to various factors. Given the current general uncertainty in the equity and U.S. natural gas drilling markets, Transocean is unsure when the transaction could be completed on acceptable terms. Transocean does not expect to sell all of its interest in TODCO in the initial public offering. Until Transocean completes the initial public offering transaction, Transocean plans to continue to operate and account for TODCO as its Gulf of Mexico Shallow and Inland Water segment. (b) Purchases. To Transocean's knowledge, no officer, director or affiliate of Transocean is the holder of any debentures. ITEM 10. Financial Statements of Certain Bidders. Transocean believes that its financial condition is not material to a holder's decision with respect to the Offer because the consideration being paid to holders surrendering debentures consists solely of cash, the Offer is not subject to any financing conditions, the Offer applies to all outstanding debentures and Transocean is a public reporting company that files reports electronically on EDGAR.
