ADDITIONAL WORK FOR ATWOOD OSPREY

In February 2017, Atwood Oceanics amended its drilling services contract with Woodside Energy to substitute the Atwood Condor for the Atwood Osprey for the Greater Enfield campaign. The contract is expected to commence between December 2017 and March 2018 at an operating rate of $222,295 per day for approximately 550 days. Depending on the commencement of the contract, Woodside will reimburse us for the mobilization of the Atwood Condor to Australia in an amount of either $34.5 million or $36.5 million. In addition, Atwood entered into a new agreement with Woodside to utilize the Atwood Osprey for an additional exploration well with an estimated duration of approximately 100 days. The contract for the exploration well is expected to commence between March 2018 and May 2018 at an operating rate of $190,000 per day with a priced option for an additional well. . Atwood Osprey is an ultra-deepwater semi-submersible built in 2011 at Jurong Shipyard, Singapore. (Source: Atwood Oceanics)
