Additional Information and Where to Find it

In connection with the Company’s offer to acquire all outstanding shares of Songa Offshore SE (the “Offer”),  the Company and Transocean, Inc. (collectively referred to as the “Offeror”) have filed with the SEC a Registration Statement on Form S-4 (the “Registration Statement”) containing a prospectus with respect to the Consideration Shares and Exchangeable Bonds to be issued in the Offer (the “Prospectus”).  The Offeror has distributed the Prospectus to certain securityholders of Songa Offshore in the United States in connection with the Offer. The Offeror has also filed an offer document with the Financial Supervisory Authority of Norway (the “Norwegian FSA”).

INVESTORS AND SECURITYHOLDERS ARE URGED TO READ CAREFULLY THE PROSPECTUS REGARDING THE OFFER IN ITS ENTIRETY (INCLUDING ANY AMENDMENTS OR SUPPLEMENTS THERETO) AND ANY DOCUMENTS WHICH ARE INCORPORATED BY REFERENCE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE TRANSACTION. You may obtain, free of charge, copies of the Prospectus and Registration Statement and other relevant documents filed by Transocean with the SEC, at the SEC’s website at:  http://www.sec.gov.  In addition, shareholders may obtain free copies of the Prospectus and other relevant documents filed by Transocean with the SEC from Transocean’s website at: http://www.deepwater.com. 

This communication does not constitute an offer to buy or exchange, or the solicitation of an offer to sell or exchange, any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, sale or exchange would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. This communication is not a substitute for any prospectus or any other document that the Offeror may file with the SEC in connection with the proposed transaction. The final terms and further provisions regarding the Offer are disclosed in the offer document filed with the Norwegian FSA, the Prospectus and the Registration Statement. No money, securities or other consideration is being solicited, and, if sent in response to the information contained herein, will not be accepted.

No offering of securities shall be made except by means of a prospectus meeting the requirements of the U.S. Securities Act of 1933, as amended, and any applicable European and Norwegian regulations. The transaction and distribution of this document may be restricted by law in certain jurisdictions and persons into whose possession any document or other information referred to herein should inform themselves about and observe any such restrictions. Any failure to comply with these restrictions may constitute a violation of the securities laws of any such jurisdiction. No offering of securities will be made directly or indirectly, in or into any jurisdiction where to do so would be inconsistent with the laws of such jurisdiction.
