Marathon holds a 70 percent working interest in the 1.2 million-acre Pasangkayu Block, located on and offshore the island of Sulawesi in the Makassar Strait, directly east of the prolific Kutei
Basin oil and gas production region.

Approximately 10 percent of the block is located on Sulawesi, with the remaining 90 percent in water depths up to 7,200 feet. Water depths for the prospects range from 4,500 feet to 6,900 feet. Marathon signed a Production Sharing Contract with the Indonesian government in 2006.

The Company completed 3-D seismic acquisition in May 2008. Marathon led a consortium of
six companies to secure a two-year rig contract for Indonesia. The Global Santa Fe Explorer will commence drilling in Indonesia in 2010. The consortium has the option to extend this rig contract.

Marathon also holds a 49 percent interest and operatorship in the Bone Bay Block offshore Indonesia. The Bone Bay Block is approximately 1.23 million acres and is located predominantly offshore southern Sulawesi Island, in the Bone Bay region. It is a high potential, underexplored area with water depths ranging between 165 to 6,500 feet. The Bone Bay Block is about 200 miles southeast of Marathon's Pasangkayu Block.

The Company was awarded a 49 percent interest in the Kumawa Block offshore Indonesia in May 2009. Komodo Energy LLC, a subsidiary of Black Gold Energy LLC, was awarded the remaining 51 percent interest. Marathon will serve as the operator. The Kumawa Block encompasses approximately 1.24 million acres and is located offshore West Papua, Eastern Indonesia, in the Semai region, approximately 180 miles south of the recently commissioned Tangguh liquefied natural gas facility. The Kumawa Block is a high-potential, under-explored area with water depths ranging from 2,400 to more than 4,000 feet.
