Sevan Drilling Ltd: Sevan Drilling Ltd amends drilling contracts and secures new employment for Sevan Driller

Reference is made to the Fourth Quarter Earnings Release on February 25, 2016, Sevan Drilling Limited ("Sevan Drilling" or the "Company") amended contracts for the Sevan Driller and Sevan Brasil with Petroleo Brasileiro SA ("Petrobras") and secured short-term employment for Sevan Driller in Brazil with Shell do Brasil ("Shell") commencing in the second quarter 2016. In December 2015, the Sevan Driller contract was suspended by Petrobras as part of the ongoing commercial negotiations for both of Sevan Drilling's units employed with Petrobras. Today, Petrobras and Sevan Drilling executed an early termination of the Sevan Driller contract and reduction of the contract dayrate on the Sevan Brasil. The Company determined on balance that this was the preferred alternative to potentially having both contracts terminated and exposing the Company to a protracted legal challenge with an uncertain outcome. As a result, the Company was able to preserve $220 million of contracted revenue backlog for the Sevan Brasil contract and to allow the Sevan Driller to obtain alternative employment. The Sevan Brasil contract dayrate has been reduced to US$250,000 per day effective 26 February 2016 through the remaining term of the contract, ending July 2018 and a portion of the dayrate continues to be denominated in Brasilian Reals. The Sevan Driller contract was mutually agreed to be cancelled effective from 1 December 2015. Subsequent to the effective cancellation of the contact for the Sevan Driller, the unit has been awarded a well intervention contract by Shell in Brazil for 60 days with two 30 day options commencing in the second quarter of 2016, adding approximately US$11 million in revenue backlog. Daily operating cost is expected to be significantly lower as the rig will perform non-drilling activities for Shell. As of 26 February 2016, the Company's total contracted revenue backlog is now estimated at $509 million, including the extension of the Sevan Louisiana contract amended in November 2014.

Seadrill increases ownership in Sevan Drilling

Seadrill has purchased an additional 116,934,875 shares in Sevan Drilling to increase the company’s holding in its fellow offshore drilling operator to over 50%. The acquisition of the additional almost 117 million shares cost Seadrill around US$76 million and the company set out its intention to submit a mandatory offer for the remainder of Sevan Drilling shares in the market. A successful takeover of Sevan would increase Seadrill’s semi-submersible fleet by four units and also give the operator an increased presence in the Brazilian offshore market where the ‘Sevan Driller’ and ‘Sevan Brasil’ units are currently operating.
