RESERVES

Total proved plus probable reserves in Colombia have increased by 51%, based on the DeGolyer and MacNaughton ("D&M") evaluation as at December 31, 2007. All reserves stated herein are based on forecast prices and costs and are company interest reserves after Ecopetrol's (the State oil company) share, and before royalties.

Summary results of the D&M report are highlighted as follows:

- Total proved reserves increased by 52% to 20.6 million barrels.

- Total proved plus probable reserves increased by 51% to 37.0 million barrels.

- Total proved, probable and possible reserves increased by 53% to 51.9 million barrels.

- Total proved plus probable NPV 10% (before taxes) increased 152% to $1.3 billion (3P - $1.8 billion).

FINANCIAL & OPERATING HIGHLIGHTS

In 2007 we launched a significant exploration campaign to position ourselves for long-term growth. The program was highlighted by our Corcel discovery which has resulted in significant increases in production. We continued our development at Orito and recent production increases have demonstrated our success leading into our 2008 development drilling program. Our financial and operating results for the fourth quarter of 2007 highlights significant increases over the fourth quarter of 2006 as follows:

- Crude oil production increased by 304%, averaging 9,575 barrels per day, mainly due to production from our Corcel discovery.

- Operating netbacks increased by 60% to $62.50/bbl.

- Funds flow from operations increased by 668% to $51.8 million.

- Net income increased by 778 percent to $23.5 million.

OPERATIONAL UPDATE

Production has averaged 8,927 bopd in February 2008 which includes 4,929 bopd from Corcel. In April we plan to run electrical submersible pumps with capacities of 15,000 barrels of fluid per day in both our Corcel-1 and 2 wells which are expected to increase Corcel production. The high fluid rates concurrent with increasing water cuts will allow us to maximize the ultimate recovery of original oil in place.

We continue to test our Corcel-3 well. An additional 600 feet of geological section was drilled in Corcel-3 below what was previously thought to be economic basement. During the drilling of the additional section, we encountered sands with oil and gas shows before drilling was terminated and the decision to case the well was made. Three of these new intervals were evaluated, two unsuccessfully, and the interval from 12,449 feet to 12,461 feet was perforated and successfully tested 27 degree API crude oil at rates up to 760 bopd, with fluctuating water cuts. We have temporarily suspended this interval. The test interval from 12,240 to 12,258 in the lower Guadalupe has been tested and produced 100% water. We plan to test one additional uphole zone.

We then plan to drill our next Corcel well, Corcel-4, vertically on the crest of the structure. This will allow us to fully evaluate the potential of the lower zones encountered in Corcel-3 in a significantly up-dip location, access attic oil in the Guadalupe and Mirador zones, and drill a well all the way to economic basement. The lower sand unit in Corcel-3 was not seen in Corcel-1, as the well was not drilled deep enough but in Corcel-2 the lower sand is over 75 feet thick and approximately 95 feet structurally higher than the interval tested in Corcel-3. The Corcel-4 well is expected to be 150 feet up-dip of the Corcel-3 well. We also plan to drill the Corcel-C prospect as our next Corcel exploration well during the second quarter of 2008, after the surface location is constructed.

On our Joropo Block, the Ojo de Tigre-3 well has been completed in the Carbonera formation. We have perforated 17 feet of C7 sands and will begin production testing the well using a jet pump system within the next week.

Our Casanare Este-2 well reached a total depth of 10,570 feet on February 27. We plan to log the well over the next week.

Our first exploration well on the Las Aguilas Block, Conga-1, was drilled in late 2007, yielding a new pool discovery. While the well demonstrated non-commercial quantities of hydrocarbons in the Caballos zone, the primary formation in Orito, it was completed as an oil well in the lower Villeta formation. We plan to test additional up-hole Villeta potential in this well and test the Villeta zones in our closest Orito well, Orito-133, in 2008.

Our first phase seismic work commitments on our Llanos Basin heavy oil blocks are nearly complete and are now being interpreted. On the Chiguiro Oeste and Rio Ariari Blocks, we have competed shooting 576 kilometres of reconnaissance 2D seismic. On the Chiguiro Este Block, we are shooting a reconnaissance 2D program, and a 3D seismic program to better define two channel systems previously identified from 2D seismic. These programs are expected to be complete in early March.
