Annual General Meeting to be held on May 14, 2010

 

Dear Transocean Shareholder:

 

The Annual General Meeting (AGM) of Transocean Ltd. is scheduled to be held on Friday, May 14, 2010 at the Parkhotel Zug, Industriestrasse 14, CH-6304 Zug, Switzerland at 4:00 p.m. CET.  The Board of Directors of Transocean Ltd. invites all shareholders to attend the AGM and submit their votes.

 

Transocean Ltd. is incorporated in Switzerland, has issued registered shares and trades on the NYSE.  In addition to the listing on the NYSE, Transocean Ltd. has applied to list its registered shares on the SIX Swiss Exchange, with the first trading day expected to be on April 20, 2010.  Share blocking or re-registration are not requirements for any Transocean shares registered in the share register as of the record date of April 26, 2010 with the right to vote by proxy or to be represented at the AGM.  All shares may be traded after the record date.

 

Transocean Ltd. has retained D. F. King as its proxy solicitor to assist with the voting process.  If you receive any notice from your custodian or proxy agent indicating that share blocking applies to this meeting, please contact our proxy solicitor D. F. King for clarification.

 

Proxy materials were previously sent to you on or about April 1 and you should have received your material through your custodian or nominee.  Our proxy statement and Annual Report are available online at http://www.deepwater.com/proxymaterials.cfm.

 

Submission of your voting instructions to your custodian(s) who are the registered holders should be communicated well in advance of the AGM in order for your votes to be counted.  Only proxies submitted by your custodian will be accepted for the meeting.  Your custodian should submit your voting instructions via proxy on your behalf.

 

Should you have any questions regarding the voting process or require additional information, please contact our proxy solicitor D. F. King at the telephone numbers indicated below:

 

 

 

Thank you in advance for your assistance and cooperation.

 

Sincerely yours,

Transocean Ltd.
