On April 29, 2013 Transocean Ltd. distributed the following notice to certain institutional shareholders via e-mail:


Dear Shareholder,

Please be advised that the Annual General Meeting of Transocean Ltd. will be held on May 17, 2013 in Zug, Switzerland.

A presentation to investors, the Proxy Statement, the 2012 Annual Report and other documents relating to the AGM are available at www.transoceanvalue.com

You may receive solicitation materials from a dissident shareholder, Carl C. Icahn and certain of his affiliates (collectively, the ''Icahn Group''), seeking your proxy to vote for his three nominees to become members of the Board of Directors and a dividend out of the company's paid-in capital to shareholders in lieu of the Board's distribution proposal.

We urge you to discard any Gold proxy card Mr. Icahn may provide you and instead to return a
WHITE proxy card voting in support of your Board's recommendations.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE:
FOR the election of the company's Board nominees: Frederico F. Curado; Thomas W. Cason; Steven L. Newman; Robert M. Sprague; and J. Michael Talbert.
FOR our proposal of a distribution of qualifying additional paid-in capital in the form of a dividend in the amount of USD $2.24 per outstanding share of the company.

YOUR VOTE IS EXTREMELY IMPORTANT. Your Board does not believe that Mr. Icahn is acting in your best interests. We urge you to protect the future of your investment in Transocean by voting on the company's WHITE proxy card today in support of your Board's recommendations.

PLEASE ALSO NOTE:
Transocean Ltd. is incorporated in Switzerland, has issued registered shares and trades on both the New York Stock Exchange and the SIX Swiss Exchange, share blocking and re-registration are not requirements for any Transocean shares to be voted at the meeting and all shares may be traded after the record date.






If you receive any notice from your custodian or proxy agent indicating that registration is required or that share blocking applies to this meeting, please contact us for clarification.



Contact your custodian or your proxy voting service as to their voting deadlines
PLEASE VOTE AS SOON AS POSSIBLE TO ENSURE YOUR VOTE IS COUNTED
