Calvalley has a strong balance sheet with approximately $87 million in working capital at December 31,

2013. The working capital balance increases to $89 million with inventory of crude oil valued at current market value rather than cost.

Subsequent to the interruption of transportation of crude oil to the Masila Export Pipeline System in late December 2013, the Company initiated trucking crude oil in early February 2014 to Block 18 and has transported over 40,000 barrels to date.

The Company has initiated production from some wells in the Hiswah Field and started to empty storage tanks at Ras Nowmah and is optimizing production operations given the local conditions, which continue to be unstable.

The Company is working with both Government and local groups to resolve the issues that are affecting transportation of crude oil to Block 51. Drilling operations have been suspended due to the inability of service companies to mobilize staff and equipment to Block 9.
