A summary of our results for years ended December 31, 2011 and 2010 is as follows:

							Percentage Increase /
	2011			2010			(Decrease)
Revenues	$	2,624,469		$	522,896			402	%
Costs and expenses		(6,941,877	)		(10,741,873	)		(35	)%

Net income (loss)	$	2,972,338		$	(4,298,370	)		(169	)%

Revenues

We earned oil and gas revenues of $2,624,469 for the year ended December 31, 2011, compared to $522,896 for the year ended December 31, 2010. This increase was mainly due to higher volume produced, which in 2011 was 35,148 barrels and in 2010 was 7,530 barrels.   These revenues were derived from our production operations in the Mirto-1 and Mirto-2 wells.

Costs and Expenses

Our operating costs and expenses for the year ended December 31, 2011 and 2010, consisted of the following:

					Percentage Increase /
	2011		2010		(Decrease)
Operating costs	$	1,072,940	$	1,554,325		(31	)%
Depreciation, depletion, accretion and amortization		233,818		297,896		(22	)%
Impairment expense		-		3,563,417		(100	)%
General and administrative		5,635,119		5,326,235		6	%
Total	$	6,941,877	$	10,741,873		(35	)%

Operating Costs

Our operating costs for the year ended December 31, 2011, which pertain to our costs incurred in production activities for the Mirto-1 and Mirto-2 wells, amounted to $1,072,940 compared to $1,554,325 in year 2010. Decrease is mainly due to adjustments received from the operator of the field.

Depreciation, Depletion, Accretion and Amortization Expenses

The decrease in our depreciation, depletion, accretion and amortization expenses for the year ended December 31, 2011 as compared to 2010 was mainly due to the lower depletion charge recorded in 2011, which originated from a reduction of the cost basis subject to depletion related to the impairment charge recorded in 2010.

3

Impairment Expense

We did not record any impairment expense during 2011 because the estimated future net cash flows associated with our reserves exceeded our net basis as of December 31, 2011. In 2010, our analysis concluded in the need of an impairment to be recorded.

General and Administrative Expenses

We incurred total general and administrative expenses of $5,635,119 for the year ended December 31, 2011 compared to $ 5,326,235 for the year ended December 31, 2010. The increase was primarily due to the equity-based tax effective January 1, 2011 by the Colombian tax authorities on all Colombian entities for the amount of $779,419, which was partially offset by a decrease in professional fees for the amount of $472,072

Non-Operating Income, Net

Net non-operating income for the year ended December 31, 2011, was $7,329,145, compared to net non-operating income of $5,971,498 for the year ended December 31, 2010. The increase is primarily due to the recognition of an unrealized gain from the decrease in the fair value of derivative warrant instruments liability of $7,356,543 during the year ended December 31, 2011compared to an unrealized gain of $5,809,716 during the year ended December 31, 2010. The derivative liability decreased due to the Company’s declining stock price.

Net Income (Loss)

Net income for the year ended December 31, 2011, was $2,972,338 compared to a net loss of $4,298,370 for the year ended December 31, 2010.  The change is primarily due to an increase in revenues of $2,101,573 as a result of a full year of production in 2011 compared to only a few months of production in 2010; no impairment of oil properties in 2011 compared to a $3,563,417 impairment charge in 2010; and an unrealized gain on fair value of derivative warrant instruments of $7,356,543 in 2011 compared to an unrealized gain of $5,809,716 in 2010.

The foregoing information is preliminary and unaudited and may be subject to change in the Report when filed.
