This document may contain forecasts regarding the financial position, results, business and industrial strategy of Maurel & Prom. By their very nature, forecasts involve risk and uncertainty insofar as they are based on events or circumstances which may or may not occur in the future. These forecasts are based on assumptions we believe to be reasonable, but which may prove to be incorrect and which depend on a number of risk factors, such as fluctuations in crude oil prices, changes in exchange rates, uncertainties related to the valuation of our oil reserves, actual rates of oil production rates and the related costs, operational problems, political stability, legislative or regulatory reforms, or even wars, terrorism and sabotage.
