Javier Gutierrez, Chief Executive Officer of Ecopetrol, highlighted that “I am very pleased with 2009´s results. We ended the year with great achievements in the execution of our growth strategy: strengthened our balance of reserves, ending the year with 1,878 m BOE, a 35.5% growth when compared to 2008, Group’s production rose 17%, made advances in the development of key projects, including the expansion of our heavy crude transportation capacity and the fuel hydro-treatment project and started to deliver cleaner diesel, which shows our commitment of improving the quality of air and the environment.”

Gutierrez added, “our Group grew with the acquisition of four companies, the expansion of our international activity with 25 new exploration blocks, and our commercial operation was strengthened with higher exports of crude and product to Europe, Africa and Asia.”

“Additionally, the strength of our financial results allowed us to raise COP 5.4 trillion in the Colombian and international capital markets, in order to finance our Capex investments. Our company continues to have strong cash flow generation, as well as the solid capital structure. These strengths were one of the elements considered by Moody´s when rating our international bonds as investment grade.”

Market conditions

In 2009, our local sales grew 5.2% in average, mainly in crude oil, natural gas, industrial and petrochemical products. Local demand for liquid fossil fuels decreased due to the mandatory blend with biofuels (7% for diesel and 8% for gasoline).

Domestic sales grew by 14.9% in the last quarter of 2009 driven by the increase in diesel and natural gas sales to thermal power generators which increased their energy production as a result of the “El Niño” phenomenom, which resulted in less hydroelectric power generation due to drought. The rise in demand for natural gas led to national production of 1,037 Gbtud, the highest level of production in Colombia’s history, of which Ecopetrol produced 64%.

Sales of petrochemical and industrial products rose 27.1% in the last quarter of 2009 as compared to the fourth quarter of 2008 and 7.5% year-over-year as a result of the general economic recovery, which resulted in higher industrial demand for aromatic solvents, lubricants and paraffin.

In the development of its export markets, the Company advanced in its market diversification strategy by increasing its exports of crude oil and products to Europe, Africa and Asia. In that way, we made asphalt exports to Nigeria and Angola and signed a long-term contract to sell crude to India, which allowed shipments for $100 million in 2009

PRESS RELEASE

In the fourth quarter of 2009, products exports decreased as a result of (i) higher local demand for naphtha (which is used as a diluter for the increasing production of heavy crudes) and (ii) a decrease in exports of natural gas to Venezuela as a result the higher Colombian demand for natural gas which was given priority to supply, in order to support local thermal power generation.

Ecopetrol´s financial results showed a positive trend throughout the year, with quarterly growth in total sales, operating profit and EBITDA.

In the fourth quarter of 2009, higher oil prices and export volumes generated a 38.6% increase in total sales, when compared to the same period in 2008. The Company had sustained sales growth in every quarter. Nonetheless, when compared to 2008, revenues full year 2009 decreased by 15.5% when compared to as a result of lower crude oil and products prices.

In the fourth quarter of 2009, variable costs grew 9.2%, when compared to the same period in 2008. This increase was mainly due to higher average prices for purchases of crude oil (which rose from US$66.20/barrel to US$70.14/barrel) and to higher volumes of low-sulfur diesel imports in the last quarter of 2009 to meet the low-sulfur requirements effective on January 1, 2010. For 2009 the decrease in variable cost was 8.7% compared to 2008. On the other hand, amortizations and depletions were reduced in 99.7% due to the recalculation as of December 31 of 2009 with a higher hydrocarbon reserves base. Regarding full year 2009, variable costs declined 8.7% when compared to 2008.

Fixed costs increased by 7.3% in the fourth quarter of 2009 when compared to the same quarter in 2008, due mainly to an higher contracted services and maintenance needed to support increasing production levels as well as higher labor costs. For the full year 2009, fixed costs increased by 8.2% compared to the same period in 2008. In addition to the fourth quarter items mentioned above, the full year growth in fixed costs is also a result of rising hydrocarbon transportation costs, due to the use of trucks for transporting hydrocarbons, and transportation costs for the delivery of natural gas form the Guajira pipeline to the Barrancabermeja refinery.

PRESS RELEASE

Ecopetrol continued its procurement cost saving strategies (including tax exemptions and negotiation options) which lead to savings of COP$288.7 billion during the fourth quarter of 2009, compared to COP$95 billion in the fourth quarter of 2008. For the full year 2009 the savings amounted to COP$607.6 billion, compared to COP$272 billion in 2008. These strategies also allowed to the Company to avoid COP$202 billion in expenses during 2009.

Operating expenses decreased by 2.5% in the fourth quarter of 2009 when compared to the fourth quarter of 2008. This reduction is principally due to a 20.6% decrease in exploration and project expenses. This is mainly due to the reduction of 20.6% in exploration and project expenses because of: 1) Lower seismic activity in the fourth quarter of 2009 as compared to the same quarter of 2008 and; 2) Lower amortization of wells for the fourth quarter of 2009 as compared to the same period of 2008.

For full year 2009, operating expenses increased by 19.2% when compared to 2008, due to higher expenses resulting from unsuccessful exploratory activities and the amortization of the goodwill of the companies acquired during 2009.

Non-operating profit decreased in the fourth quarter of 2009 compared to the same quarter in 2008, amounting to a loss of COP$455.5 billion in 2009 compared to a profit of COP$1,988.8 billion in the fourth quarter of 2008. This loss was primarily due to the impact of the Colombian peso revaluation during the fourth quarter of 2009 on the dollar-denominated investments in the Company’s financial portfolio which generated a book net loss. Additionally, during 2009 the Company accounted for interest expenses relating to indebtedness incurred in 2009.

For full year 2009, the Company had a COP$23.4 billion loss in non-operating results; again due to the Colombian peso revaluation. It is worth mentioning that exchange rate risk in dollar-denominated assets has been partially offset by the dollar-denominated debt raised in 2009.

Net profit for the fourth quarter of 2009 amounted to COP$1,691.4 billion, or COP$41.79 pesos per share, a 17.6% decrease compared to the net profit reported for the fourth quarter of 2008 which amounted to COP$2,052.3 billion, or a profit of COP$50.71 pesos per share. Nonetheless, net profit rose 42% when compared to the third quarter of 2009 when net profit was COP$1,193.5 billion.

For full year 2009, net profit amounted to COP5,256.2 billion, or COP$129.87 per share, a 54.8% decrease when compared to the same period in 2008, mainly due to the decrease in WTI prices.

PRESS RELEASE

EBITDA for the fourth quarter of 2009 was COP$2,963.6 billion, 158% higher compared to COP$1,150.9 billion during the same quarter of 2008 and a 2.4% decrease compared to the third quarter of 2009. EBITDA margin was 35%, compared to a 19% margin in the fourth quarter of 2008 and a 41% margin in the third quarter for 2009. The growth between fourth quarter of 2009 and 2008 EBITDA was due to a higher crude production, as well as the cost saving measures meant to decrease operating costs.

As of December 31, 2009, Ecopetrol´s assets amounted to COP$53,092 billion compared to COP$51,626 billion as of September 30, 2009. During the fourth quarter cash (and cash equivalents) decreased in order to pay suppliers as well as the payment of third installment of the 2009 dividend. Long-term assets rose as a result of the capitalization of property, plant and equipment, as well as to capitalizations in subsidiaries.

Liabilities amounted to COP$20,389 billion as of December 31, 2009 compared to COP$22,181 billion as of September 30 of 2009. The decrease in current liabilities was due to the payment of the third installment of the 2009 dividend payment, which amounted to COP$2.938 billion. Long-term liabilities increased mainly as a result of recognized provisions for abandonment costs of COP$1,008 billion.

Shareholders’ equity increased from COP$29,445 billion at September 30, 2009 to COP$32,703 billion at December 31, 2009, as a result of (1) a COP $1,691 billion growth in net income and (2) a COP$712 billion reversal of a provision relating to technical asset assessment.

Note: This segment analysis is calculated based on transfer prices between business units, using export parity prices as reference.

The Exploration and Production segment generated COP$1,945.5 billion to the Company’s net income in the fourth quarter of 2009 and COP$5,707.1 billion for full year 2009, mainly driven by the growth in the production of heavy crude oil for export.

The Refining and Petrochemical segment accumulated net losses of COP$103.9 billion during the fourth quarter and COP$489 billion for full year 2009. The losses were due to the narrowing of the crack spreads when compared to 2008, which decreased the refining margin.

The hydrocarbon Transportation segment generated net income for the fourth quarter of 2009 of COP$291.2 billion, mainly due to the revenues from higher transported volumes during the fourth quarter of 2009, which reached 859.5 Mbod compared to 785.7 Mbod in the third quarter of 2009. For the full year 2009, the transported volume was 799.5 Mbod, a 47.7 Mbod increase when compared to 751.8 Mbod in 2008.

The Marketing and Sales segment had net income of COP$132.2 billion in 2009, as a result of the improvement of the hydrocarbon sales margin during the fourth quarter of 2009.

The Corporate segment generated an accumulated net loss of COP$385.4 billion in 2009, mainly due to other non-operating expenses, such as interest payments, net worth tax and retiree expenses.

Starting 2010 our segment reporting methodology will be modified. The primary modification refers to changes for the reporting of the Sales and Marketing segment, as it will no longer take “theoretical ownership” of crudes and products from the Exploration & Production and Refining & Petrochemical segments. In summary: revenues, costs, and expenses related to commercialization and delivery to end client (exports or refined), will be allocated to their respective segments. Under the current methodology these items are allocated to the Sales and Marketing segment. Additionally, Corporate segment costs will be gradually allocated among other segments, and we anticipate that in the future this segment will be eliminated and will no longer be included in the report.

At December 31, 2009 Ecopetrol and its subsidiaries´ 1P proved reserves amounted to 1.88 billion barrels oil equivalent (BOE), including royalties, based on SEC standards and prices. This represented a 35.5% in proved reserves when compared to 1.38 billion BOE at the end of 2008. 71% of the reserves correspond to crude oil and 29% to natural gas.

The reserves replacement ratio was 359% for 2009 compared to 37.3% for 2008. At the end of 2009, the consolidated reserves-to-production ratio (assuming future production will remain at 2009 levels) was 9.9 years. The Company added a total of 682 million BOE of proved reserves.

The growth in proved reserves was a result of the following:

Field Production Revaluation: 572 million BOE

2009 Acquisitions: 108.5 million BOE

New Discoveries : 63 million BOE

Price Variation: Negative 61 million BOE

The largest reserves addition came from the Central Region (37%), mainly from the Castilla and Chichimene fields, both located in the Meta province and operated by Ecopetrol. The North East region was second largest in reserves addition (29%), the main contributor of which was the Pauto field located in the Casanare province and operated by BP.

At December 31, 2009, applying company prices to SEC technical standard, Ecopetrol and its subsidiaries´ proved reserves amounted to 1.79 billion BOE, a 22% increase compared to 1.47 billion BOE in 2008.

Exploration

19 exploratory wells were drilled during 2009 (16 in Colombia, 2 in the US Gulf Coast and 1 in Brazil). Five wells exhibited preliminary evidence of hydrocarbons: the Quriyana-1 and Tempranillo-1 wells (operated by Ecopetrol), and the Quifa-7, Quifa-8 and Quifa-9 wells operated by Meta Petroleum LTD. Since five of the 19 drilled wells were successful, the global exploratory success rate was 26% in 2009 compared to 33% in 2008 (5 successful wells out of 15 drilled wells).

Out of the 19 exploratory wells drilled in 2009, 7 were drilled during the last quarter of 2009 (6 in Colombia and 1 in Brazil) as compared to the 6 exploratory wells drilled during the fourth quarter of 2008, when 2 wells proved successful.

PRESS RELEASE

This agreement is awaiting authorization from the Agencia Nacional de Hidrocarburos (“National Hydrocarbons Agency” or the “ANH”)

PRESS RELEASE

Production

2009 was an important year for this segment, not only because of the incorporation of hydrocarbon reserves (mainly as a result of projects allowing the revaluation of existing fields), but also because of the growth in crude oil and natural gas production.

The annual average gross equivalent production of crude oil and natural gas of the Ecopetrol´s Group grew by 17% in 2009 from 447 Mboed (361.6 Mbod of crude oil and 85.4 Mboed of natural gas) in 2008 to 520.6 Mboed (426.04 Mbod of crude oil and 94.6 Mboed of natural gas) in 2009. Production in 2009 includes 0.99 Mboed from the K2 field in the US Gulf Cost.

During December 2009, the Ecopetrol Group’s average gross production reached 549.4 Mboed (449.8 Mbod of crude oil and 99.6 Mboed of natural gas), an increase of 32% compared to the 440.4 Mboed (360.5 Mbod of crude oil and 79.9 Mboed of natural gas) reported in December 2008. This growth is largely the result of: (1) a 38% increase in the production of heavy crudes, mainly in the Central region (Chichimene and Castilla fields), (2) the successful water injection projects in mature fields which led to a 11% growth, and 3) the higher demand for natural gas demand which led to a 9% increase.

The Company participated in the drilling of 162 development wells in the fourth quarter of 2009 (52 directly and 110 in partnership) compared to 185 development wells in the fourth quarter of 2008. In 2009, 587 development wells were drilled, compared to 618 in 2008.

Ecopetrol´s average lifting cost for the year 2009 was USD$7.23/barrel, compared to USD$8.32/barrel in 2008. This cost reduction was mainly due to higher production.

Refining and Petrochemicals

During 2009 Ecopetrol finalized the acquisition of 51% of Reficar, which is key in the integration of the modernization projects for the Barrancabermeja and Cartagena refineries. The modernization plans in both refineries will generate potential estimated configuration and construction savings of US$0.91 billion.

As of December 31 2009, the hydro-treatment project at the Barrancabermeja refinery was 94.4% complete, and operations are expected to start during the first half of 2010.

As part of the petrochemical development plan for Ecopetrol, the Barrancabermeja refinery rose its polyethylene production capacity by 10,695 tons/year, a 19% growth. Likewise, propylene deliveries increased by 31,970 tons/year (36% increase). However, Barrancabermeja refinery’s load decreased during 2009 due to unfavorable market conditions.

During the fourth quarter of 2009, the prices of products were negatively impacted by the worldwide growth in inventories, especially gasoline, as a result of stockpiling for the hurricane season in the Gulf Coast, which ended up being slower than anticipated. Consequently the increase in supply of products was exacerbated by depressed demand as a result of the unfavorable economic conditions.

The accumulated refining gross margin4 for 2009 in the Barrancabermeja refinery amounted to US$4.41/barrel, an increase from the US$3.53/barrel reported in 2008, mainly due to: (a) the improvement in margins for fuel oil, whose differential was approximately 97% of the WTI price for 2009, compared to 76% in 2008, and (b) the lower average cost of raw materials (U$56.25 as compared to 96.24 US$/Barrel in 2008).

Refining cash cost in 2009 amounted to US$5.95/barrel, US$0.18 higher than the US$5.77/barrel reported for 2008. The increase was due to higher consumption and price of the catalysts, higher labor costs, and a load reduction.

Cleaner Fuels

As a result of the strategy undertaken by Ecopetrol in order to improve the quality of fuels, starting in July 2009, sulfur content in diesel fuels was reduced from 1,000 ppm to 500 ppm in Bogota, and from 3,000 to 2,500 ppm in the rest of the country. Subsequently, on January 1, 2010, sulfur contents in diesel fuels were reduced from 2,500 parts per million to 500 ppm for the rest of the country. For Bogota, and for the mass transportation systems in Bucaramanga, Pereira and Cali, Ecopetrol began delivering diesel fuels with less than 50 ppm of sulfur, demonstrating our commitment to improve the quality of air in Colombia.

4 2008 and 2009 margins were calculated based on accounting information, which includes inventory adjustments.

PRESS RELEASE

Transportation

During 2009, Ecopetrol achieved significant progress in the consolidation of the heavy crudes transportation system in the Llanos Orientales, undertaking several projects to increase the transportation capacity of the Araguaney-Porvenir, Ocensa, and the Oleoducto Colombia pipelines. Additionally, the Apiay-Porvenir pipeline began operations with a capacity of 160 Mbod.

Likewise, the Poliducto de Oriente transportation system, which runs from Sebastopol to Tocancipá, commenced operations. This transportation system delivers naphtha to Tocancipa. The naphtha is then moved to the Llanos Orientales (Eastern Plains) in order to facilitate the transport of heavy crude oil through the oil pipeline system. Additionally, the capacity of the Pozos Colorados – Galan line rose by 45 thousand BPD. Furthermore, 50% of the Caño Limon-Coveñas pipeline, one of the main transport systems in Colombia, reverted back to Ecopetrol in 2009.

During 2009, 501 kilometers were added to Ecopetrol´s pipelines, representing a 6% growth compared to 2008. 126 kilometers were added to the Apiay-Porvenir line, 140 kilometers were added to the Pozos Colorados – Galán line, and 235 kilometers were added to the Rubiales-Monterrey pipeline.

Transportation costs in 2009 were COP$9.13/barrel-kilometer compared to COP$9.70 in 2008 due to the 12.4% growth in transported volumes in 2009 as compared to 2008.

Investments

In 2009 total capital expenditures (CAPEX) investment amounted to COP$13.578 billion, of which COP$5.087 billion were allocated to acquisitions and COP$8.491 billion to organic investments. In comparison, total capital expenditures investment amounted to COP$9.489 billion in 2008, of which COP$7.924 billion were allocated to organic investments and COP$1.565 billion were allocated to acquisitions. 38% of total investment in 2009 was allocated to acquisitions and new business, 42% to Upstream projects, 18% to Downstream projects, and the remaining 2% to corporate internal initiatives.

Total CAPEX investment for the fourth quarter of 2009, including acquisitions, reached COP$3.424 billion, compared to COP$3.445 billion in the fourth quarter of 2008.

Financing

As part of the growth strategy, in 2009 Ecopetrol began leveraging its balance sheet in order to finance its investment plan and optimize its capital structure. In June 2009, a seven-year COP$2.2 trillion syndicated loan was entered into with eleven local banks. The repayment terms under this loan include bi-annual amortizations, a two year grace period for the repayment of principal, and an interest rate of DTF (Colombian banking system reference rate) + 4%. As security under the loan, the Company granted the lenders a pledge on a percentage of the Company’s shares in of Oleoducto Central S.A. (OCENSA), Reficar S.A. and Polipropileno del Caribe S.A. (Propilco).

Reficar

During 2009, Reficar made advances in all areas of its modernization and expansion projects, all within the established schedule. Some of the major milestones were: finalizing the basic engineering phase, signing an Engineering Procurement and Construction contract, undertaking initial negotiation of required financing for the project, beginning the purchase of long-term delivery machinery, and beginning the preparation of land where the new plants are to be built.

The final configuration of the refinery was optimized under an integration model with the Barrancabermeja refinery, thus maximizing value for Ecopetrol.

On September 22, 2009 Orlando Cabrales, former CEO of Propilco, was appointed as CEO of Reficar by its Board of Directors.

Later, in October 2009, the Board of Directors of Ecopetrol S.A. agreed to guarantee resources needed by Reficar in order to complete the refinery’s expansion.

PRESS RELEASE

Although the operation of the Cartagena refinery benefited from a lighter load of crude oil (Vasconia y Caño Limon), the reduction in margins resulted in a loss for the fourth quarter and full year 2009.

Notes

* According to the Public Accounting Framework, Colombian companies only have the obligation to consolidate their financial statements at the end of each fiscal year, wherefore the quarterly figures in this report do not constitute a formal consolidation of Ecopetrol's financial statement, though they do adjust to the methodology defined for this purpose.

** In the fourth quarter of 2008, the following reclassifications were made: from cost of sales to commercialization expenses for COP$36,608 million for freight costs; from commercialization expenses to cost of sales for COP$97,395 million for non-discountable VAT, and from commercialization expenses to other expenses - social investment expenses- for COP$20 million.
