are subject to certain risks, trends and uncertainties that could cause actual
results to differ materially from those projected. Among those risks, trends and
uncertainties are our estimate of the sufficiency of our existing capital

expenditures and drilling of wells, and the operating hazards attendant to the
oil and gas business. In particular, careful consideration should be given to
