Vast Exploration has closed its previously announced farm-out of a 90% interest in the Putumayo Basin of Colombia Block (the "Block") to a wholly-owned subsidiary of Sagres Energy Inc.

The Block has an area of 148,000 acres (gross) and is located in the Putumayo Basin of Colombia. The Block offers exploration upside on a structural trend with existing discoveries, and is situated strategically between two blocks (CAG-6 and PUT-09) awarded to Pacific Rubiales and Talisman Energy, respectively. The Block carries a royalty of 7% payable to the Government of Colombia in addition to the basic royalty scheme established under Colombia Law, being 8% for up to 5,000 bopd and increasing to 25% for a 600,000 bopd field. All other terms of the contract are standard to the model Colombian E&P Contract. Sagres will have an option to acquire the Company's Carried Interest in the Block over the next twelve months at a price to be mutually agreed.
