Explanation of Responses:

1. Shares automatically withheld upon vesting to satisfy tax withholding obligations.

2. On December 19, 2008, Transocean Ltd., a Swiss corporation, became the successor of Transocean Inc., a Cayman Islands company, pursuant to a merger by way of schemes of arrangement under Cayman Islands law (the "Transaction") in which each holder of Transocean Inc. ordinary shares outstanding immediately prior to the Transaction received one registered share of Transocean Ltd. in exchange for each outstanding ordinary share of Transocean Inc. The Transaction had the effect of changing the place of incorporation of Transocean's group holding company from the Cayman Islands to Switzerland but did not alter the proportionate interests of security holders.

3. Shares owned under the issuer's Employee Stock Purchase Plan. Includes 172 shares acquired under the issuer's Employee Stock Purchase Plan since the prior filing on July 21, 2008, the last time a Table I transaction was reported.
