Transocean and GlobalSantaFe Announce Tentative Closing Date

Transocean and GlobalSantaFe have received approval from the Grand Court of the Cayman Islands of the proposed merger and related transactions. The parties have tentatively scheduled to complete the transactions on Nov. 27, 2007. The proposed merger remains the subject of an investigation by the Office of Fair Trading for the United Kingdom (OFT), and the tentative closing date remains subject to various closing conditions.

Transocean and GlobalSantaFe expect that prior to Nov. 27, 2007, the OFT will announce its decision whether the merger raises competitive issues that could, in the absence of appropriate undertakings by the parties, warrant a reference to the Competition Commission of the United Kingdom (Competition Commission) for further review. There can be no assurance at this time (a) as to whether the OFT will refer the merger to the Competition Commission, (b) concerning the timing of any such referral decision or (c) as to whether any divestitures or other undertakings will be required by the OFT in order to avoid such a referral or by the Competition Commission in the event the merger is referred.
