Llanos Basin, Colombia

Pacific Rubiales has successfully completed a private competitive bid process for the farming out of a series of blocks in which it holds interests in Colombia and Peru, resulting in the award by the company of working interests in such blocks to third party bidders. The total amount successfully farmed out by the company will result in a US $54.2 million reduction in its exploratory commitments for the next two years, most of which is to be achieved from the farming out of two of the company's interests in Peru. In all cases the company has retained operatorship of the blocks.

The farm-out process will allow the company to continue concentrating its investments on core assets without losing the potential upside from promising exploratory activities, while also sharing part of the risk of such activities. The company plans to complete the assignment of the various participating interests awarded under the process as soon as possible.

The following is a summary of the results of the process:
