INCORPORATION BY REFERENCE The SEC allows the issuers to “incorporate by reference” the information Transocean Ltd. has filed with it, which means that the issuers can disclose important information to you by referring you to those documents filed separately with the SEC. The information the issuers incorporate by reference is deemed to be part of this prospectus, and subsequent information that Transocean Ltd. files with the SEC will automatically update and supersede this information. The issuers incorporate by reference the documents listed below and any future filings Transocean Ltd. makes with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act (other than information “furnished” and not “filed” with the SEC, unless the issuers specifically provide that such “furnished” information is to be incorporated by reference) after the date of this prospectus and until the offering is terminated. The documents the issuers incorporate by reference are:

Any statement contained in a document incorporated by reference in this prospectus shall be deemed to be modified or superseded for purposes of this prospectus to the extent that a statement contained herein or in any other subsequently filed document that also is incorporated by reference in this prospectus modifies or supersedes such statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this prospectus or any prospectus supplement. A copy of these filings will be provided upon oral or written request, other than an exhibit to these filings unless the issuers have specifically incorporated that exhibit by reference into the filing, at no cost. You may request such copies by writing or calling: Transocean Ltd.
