(1) Oil produced from the Umusadege field is sold pursuant to an oil purchase agreement with ENI Trading & Shipping S.P.A. ("ENI"), a subsidiary of ENI S.p.A. ENI S.p.A. is also the parent company of AGIP, the operator of the export pipeline. The oil purchase agreement requires that Umusadege field owners "nominate" in advance the volumes of oil to be delivered to ENI. The sales price per barrel for nominated and delivered oil is slightly higher than the average Brent price for the month in which the delivery occurs. A situation in which produced oil has not been nominated nor paid for but delivered to ENI is called an "under lift". The under lift is nominated and paid for in subsequent months. The sales price per barrel for an under lift is the month end slightly higher than Brent spot rate in which the under lift occurred.
