TRANSOCEAN LTD. BOARD SEEKS SHAREHOLDER APPROVAL FOR U.S.

$1 BILLION DIVIDEND, TWO NEW DIRECTORS

ZUG, SWITZERLAND—Transocean Ltd. (NYSE: RIG) (SIX: RIGN) today announced that the Board of Directors is recommending that the company’s shareholders approve at the 2011 Annual General Meeting a U.S. dollar-denominated dividend of approximately U.S. $1 billion out of additional paid-in capital and payable in four quarterly installments. The Board of Directors expects that the four payment dates of the proposed dividend out of additional paid-in capital will be set in June 2011, September 2011, December 2011 and March 2012.

The proposed dividend will be contingent on shareholders approving at the same meeting a rescission of the U.S. $1 billion cash distribution in the form of a par value reduction, which shareholders approved at the 2010 Annual General Meeting, but which was subsequently blocked by the Commercial Register of the Canton of Zug and the Administrative Court of the Canton of Zug. The proposed dividend amount further assumes that no payment will be made under the 2010 distribution.

Due to, among other things, the uncertainty of the timing and outcome of the pending appeal with the Swiss Federal Supreme Court, the Board of Directors believes it is in the best interest of the company to discontinue with the disputed 2010 distribution and to file a request to stay the pending appeal with the Swiss Federal Supreme Court against the decision of the Administrative Court until shareholders have voted on the proposed rescission of the 2010 distribution. Under new Swiss tax laws effective January 1, 2011, shareholders will not incur Swiss withholding tax on the proposed dividend out of additional paid-in capital. Unlike a distribution by way of a par value reduction, a dividend out of additional paid-in capital will not require registration with the commercial register.

In addition, the Board of Directors is also recommending that the company’s shareholders at the 2011 Annual General Meeting approve, among other items:

The company also announced that Robert E. Rose, the Chairman of the Board of Directors, and Victor E. Grijalva will not stand for re-election at the 2011 Annual General Meeting due to reaching the age limitation for directors as set out in the company’s Corporate Governance Guidelines. The Board will elect a new chairman following the annual general meeting.

In addition, the company announced that Richard L. George notified the company of his resignation as a director of the company with immediate effect because of the demands of his duties as President and Chief Executive Officer of Suncor Energy Inc.

The 2011 Annual General Meeting, which will open to shareholders of record as of April 26, 2011, will be held at 4 p.m., CET, on May 13, 2011, in Cham, Switzerland. Additional details on the meeting will be provided to shareholders in the company’s proxy statement.
