Re:         Total Proven Reserves Evaluation
            Regent Natural Resources Co.
            Hill County, Texas
            Effective January 1, 2011




Gentlemen:

In accordance with your request, we have prepared estimates, as of January 1,
2011 of the extent and value of the Total Proven Reserves attributable to Regent
Natural Resources Co.'s interests in the referenced properties.

This report includes projections of the Proven Reserves and associated revenues
net to the company.  The following tables summarizes the Gross and Net Reserves
and Future Cumulative Cash Flows both undiscounted and discounted at 10% prior
to the effects of Federal Income Tax.

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 $71.58 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.
