|   | (1) | Production is net and determined by multiplying the gross production volume of properties in which we have an interest by the percentage of the leasehold or other property interest we own. |
|--------|-----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (2) | A ratio of energy content of natural gas and oil (six Mcf of natural gas equals one Bbl of oil) was used to obtain a conversion factor to convert oil production into equivalent Mcf of natural gas. |
