Spinnaker Apparent High Bidder on Ten Gulf of Mexico Blocks

Spinnaker Exploration Company participated in a total of 12 bid submissions for the sale. Five of these blocks are located in water depths of less than 200 meters (shelf) and seven blocks in water depths greater than 200 meters (deep water).

Spinnaker participated in apparent high bids on a total of ten blocks; five on the shelf and five in the deep water. Spinnaker's net exposure to the AHBs is approximately $2.7 million.
