Transocean Ltd

Initial listing of Transocean Ltd. shares on SIX Swiss Exchange. The SIX Disclosure Office has granted Transocean Ltd. an extension in relation to the disclosure of the sale posititions disclosed in this disclosure notice and requested that it provide an update of its aggregate purchase and sale positions upon disclosure of the sale positions in accordance with the SIX Disclosure Office's recommendation of June 10, 2010. Transocean Inc. has granted written conversion and share purchase rights in the form of convertible senior notes (USD 1.299 billion aggregate principal amount of 1.625% Series A Convertible Senior Notes due December 2037, USD 2.2 billion aggregate principal amount of 1.5% Series B Convertible Senior Notes due December 2037, and USD 2.2 billion aggregate principal amount of 1.5% Series C Convertible Senior Notes due December 2037 (collectively, the "Convertible Senior Notes"). Under the terms and conditions contained within the indentures of the Convertible Senior Notes, Transocean Inc. will, upon occurrence of a conversion event, deliver cash up to the aggregate principal amount of the notes and accrued interest (if any). Transocean Ltd. would only be required to deliver and/or issue shares for the remainder of its conversion obligation. As long as the share price per Transocean Ltd. registered share does not exceed USD 168.61 (as increased and adjusted upon the occurrence of certain events) as quoted on the NYSE during the relevant reference period prior to a conversion event, Transocean Ltd. will not be required to issue and/or deliver any shares in addition to its cash delivery obligation. The Convertible Senior Notes do not provide for a cap on the relevant conversion price and therefore, there is no maximum number of shares issuable and/or deliverable at the date hereof and at any date thereafter prior to the occurrence of a conversion event and the lapse of the relevant reference period. The SIX Disclosure Office has therefore granted Transocean Ltd. an exemption from the requirement to disclose the number and percentage of voting rights attached to the sale positions in the form of the Senior Convertible Senior Notes. The current expectation of Transocean Ltd. is that no shares will be issuable and/or deliverable under the terms of the Convertible Senior Notes.
