Ronald Pantin, Chief Executive Officer of Pacific Rubiales, commented:  "This investment will allow us to expand and deepen the Company's position in the highly prospective offshore Guyana oil play.  We consider CGX Energy's large acreage position in Guyana to be a premier world-class exploration asset in an offshore basin with analogous geology to West Africa, Brazil and Venezuela.

"On the Corentyne Block, DeGolyer and MacNaughton in a resource report for CGX Energy effective December 31, 2012, estimated mean Prospective Resources of 1,522 MMbbl of liquid hydrocarbons (779 MMbbl of oil and 743 MMbbl condensate) and 7,889 Bcf of non-associated and associated natural gas, contained in six exploration opportunities. Additionally, the USGS in its report entitled "Assessment of Undiscovered Conventional Oil and Gas Resources of South America and Caribbean, 2012" calculated 12,494 MMboe and 18,284 Bcf of yet to find oil and gas, respectively, for the Guyana-Suriname basin. Both reports emphasized the great upside exploration potential of this basin.

"This investment is well-aligned with the Company's technical strengths, strategy of early stage large resource capture and objective of building the leading Latin American independent explorer and producer of hydrocarbons."

Boe

Boe's may be misleading, particularly if used in isolation. The Colombian standard is a boe conversion ratio of 5.7 Mcf:1 bbl and is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

Resources

Prospective Resources are those quantities of oil and gas estimated to be potentially recoverable from undiscovered accumulations.  There is no certainty that the Prospective Resources will be discovered.  If discovered, there is no certainty that it will be commercially viable to produce any portion of the Prospective Resources. Application of any geological and economic chance factor does not equate Prospective Resources to Contingent Resources or reserves.
