 and Transocean Ltd. has agreed to be served with process with respect to actions based on offers and sales of its securities. To bring a claim against either, you may serve Transocean Ltd.’s Corporate Secretary, c/o Transocean Offshore Deepwater Drilling Inc., 1414 Enclave Parkway, Houston, Texas 77077, the U.S. agent appointed for such purpose. Carey Olsen, Transocean Inc.’s Cayman Islands legal counsel, has advised Transocean Inc. that it is uncertain that Cayman Islands courts would enforce (1) judgments of U.S. courts obtained in actions against Transocean Inc. or other persons that are predicated upon the civil liability provisions of the U.S. federal securities laws or (2) original actions brought against Transocean Inc. or other persons predicated upon the Securities Act. There is no treaty between the United States and the Cayman Islands providing for enforcement of judgments, and there are grounds upon which Cayman Islands courts may not enforce judgments of U.S. courts. In general, Cayman Islands courts would not enforce any remedies if they are deemed to be penalties, fines, taxes or similar remedies. Homburger AG, Transocean Ltd.’s Swiss legal counsel, has advised Transocean Ltd. that it is uncertain that Swiss courts would enforce (1) judgments of U.S. courts obtained in actions against Transocean Ltd. or other persons that are predicated upon the civil liability provisions of U.S. federal securities laws or (2) original actions brought against Transocean Ltd. or other persons predicated upon the Securities Act. The enforceability in Switzerland of a foreign judgment rendered against Transocean Ltd. or such other persons is subject to the limitations set forth in such international treaties by which Switzerland is bound and the Swiss Federal Private International Law Act. In particular, and without limitation to the foregoing, a judgment rendered by a foreign court may only be enforced in Switzerland if:

| ● | such foreign court had jurisdiction; |

| ● | such judgment has become final and non-appealable; |

| ● | the court procedures leading to such judgment followed the principles of due process of law, including proper service of process; and |

| ● | such judgment does not violate Swiss law principles of public policy. |

In addition, enforceability of a judgment by a non-Swiss court in Switzerland may be limited if Transocean Ltd. can demonstrate that it or such other persons were not effectively served with process
