Auditor’s Report

To the Shareholders of Ecopetrol S.A.

I have audited the consolidated balance sheets of Ecopetrol S.A. (the Company) at December 31, 2006 and 2005 and the related consolidated statements of financial, economic and social activity, changes in equity, changes in financial position and of cash flows for the years then ended. These consolidated accounting statements are the responsibility of the Company’s management.
My responsibility is to express an opinion thereon based on my audits. I have not audited the accounting statements of Black Gold Re Ltd. which were audited by another independent auditor, who issued an unqualified opinion on January 22, 2007 and their amounts are not material in respect to those of the Company.
The 2005 accounting statements are only submitted for comparative purposes with those of 2006.

I conducted my audits in accordance with auditing standards generally accepted in Colombia. Those standards require that an audit be planned and performed in such a way as to obtain reasonable assurance about whether the accounting statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting amounts and disclosures in the accounting statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the accounting statements. I believe that my audits provide a reasonable basis for
my opinion.

In my opinion, the aforementioned consolidated accounting statements present fairly, in all material respects, the consolidated financial position of Ecopetrol S.A. and its subsidiaries at December 1, 2006, the consolidated results of its financial, economic and social activities, the changes in its financial position and of its cash flows for the year then ended, in accordance with generally accepted governmental accounting principles, issued by the Contaduría General de la Nación, consistently applied.
