Cautionary Statement Regarding Forward-Looking Statements This annual report on Form 10-K contains estimates and forward-looking statements, principally in ‘‘Item 1. Business,’’ ‘‘Item 1A. Risk Factors’’ and ‘‘Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.’’ Our estimates and forward-looking statements are mainly based on our current expectations and estimates of future events and trends, which affect or may affect our businesses and operations. Although we believe that these estimates and forward- looking statements are based upon reasonable assumptions, they are subject to several risks and uncertainties and are made in light of information currently available to us. Many important factors, in addition to the factors described in our annual report on Form 10-K, may adversely affect our results as indicated in forward-looking statements. You should read this annual report on Form 10-K and the documents that we have filed as exhibits hereto completely and with the understanding that our actual future results may be materially different from what we expect. Our estimates and forward-looking statements may be influenced by the following factors, among others: • our ability to find, acquire or gain access to other discoveries and prospects and to successfully develop and produce from our current discoveries and prospects; • uncertainties inherent in making estimates of our oil and natural gas data; • the successful implementation of our and our block partners’ prospect discovery and development and drilling plans; • projected and targeted capital expenditures and other costs, commitments and revenues; • termination of or intervention in concessions, rights or authorizations granted by the governments of Cote d’Ivoire, Equatorial Guinea, Ghana, Mauritania, Morocco, Sao Tome and Principe, Senegal or Suriname (or their respective national oil companies) or any other federal, state or local governments or authorities, to us; • our dependence on our key management personnel and our ability to attract and retain qualified technical personnel; • the ability to obtain financing and to comply with the terms under which such financing may be available; • the volatility of oil and natural gas prices; • the availability, cost, function and reliability of developing appropriate infrastructure around and transportation to our discoveries and prospects; • the availability and cost of drilling rigs, production equipment, supplies, personnel and oilfield services; • other competitive pressures; • potential liabilities inherent in oil and natural gas operations, including drilling and production risks and other operational and environmental risks and hazards; • current and future government regulation of the oil and gas industry or regulation of the investment in or ability to do business with certain countries or regimes; • cost of compliance with laws and regulations; • changes in environmental, health and safety or climate change or greenhouse gas (‘‘GHG’’) laws and regulations or the implementation, or interpretation, of those laws and regulations; • adverse effects of sovereign boundary disputes in the jurisdictions in which we operate; • environmental liabilities; 7
