Remaining reserves fall into these basic classifications - Proven, Producing; Proven, Non-Producing; Proven, Undeveloped; Probable and Possible. Proven, Producing Reserves are defined as wells with sufficient production history and offset production history to allow decline curve analysis to temper volumetric reserve determination. Proven, Non-Producing Reserves are defined as reserves which have been drilled and cased but are presently behind pipe, or shut-in. Proven, Undeveloped Reserves refer to zones - usually undrilled - with sufficient data available from offset well control to allow prediction of performance within an accepted tolerance. Probable Reserves refer to undrilled zones which can be correlated to Proven, Undeveloped Reserves but have not been tested. Possible Reserves refer to undrilled zones which exist in the area, but cannot be correlated to any known producing wells.

Future net revenues were determined by deduction from future gross revenues such items as estimated ad valorem taxes, severance taxes, windfall profit taxes, transportation costs, and current normal operating and development costs. Development costs are those required to drill and complete wells on undeveloped locations and the costs to recomplete in zones which are behind pipe in existing wells. Lease operating costs were provided to RCM Engineering, Inc. by Regent Natural Resources Co. and oil prices were initially set at $88.06 per barrel and held constant for the life of the properties. Lease operating costs and all other workover and/or drilling costs have also been held constant for the life of the properties.

The reserves included herein have been estimated from initial flow tests, present production data, and decline curves. These techniques have limited accuracy and possess a certain degree of uncertainty particularly in the early stages of production.

Accordingly, please note that the accuracy of any reserve estimate is solely a function of engineering interpretation and judgment and should be accepted with the understanding that future production and other events subsequent to this report could justify revision of these reserve estimates.

All well production and expense data was furnished by Regent Natural Resources Co. and was assumed to be accurate and correct. RCM Engineering, Inc. personnel have not conducted production tests or on-site inspections of the wells or production equipment. Production data was checked against data obtained from Railroad Commission of Texas records if available. The values utilized herein do not necessarily represent fair market value since this can only be determined by the inter-dealings between a willing buyer and a willing seller. All work notes used in this appraisal have been retained for review.
