Subject: Evaluation of Oil and Gas Reserves to the Interests of
         Texas Vanguard Oil Company in Certain Properties Located
         in Nebraska, New Mexico, Oklahoma, Texas and Wyoming.

Ladies and Gentlemen:

Brian K. Miller, P.E. (Miller) has completed an evaluation of proved
developed producing oil and gas reserves to the interests of Texas
Vanguard Oil Company (TVOC). This evaluation was requested by Mr.
William G. Watson.  This evaluation was based on available information
provided by TVOC and obtained from public record sources. Projections
of reserves and future net revenue to the subject interests were
based on operating conditions, economic parameters and market
conditions considered applicable as of January 1, 2011.

Detailed projections of oil and gas reserves and associated future net
revenue are included in the tables following this report letter.  These
tables include various data that describe the oil and gas reserve
forecasts, economic parameters, and associated evaluation parameters
such as interests, taxes, product prices, operating cost, and
investments, as applicable.  Following these tables are graphs of
production histories with associated reserve projections for each
individual property.

Future net revenue is income to the evaluated interests after
consideration of royalty payable to others, production (severance)
and property taxes, operating expenses and investments, as applicable.
Future net revenue is presented in this evaluation on a before
federal income tax basis and does not consider any encumbrances
against the properties if such exist. It was assumed there would be
no significant delay between the date of oil and gas production and
the receipt of the revenue.

This report includes only those costs and revenues considered to be
directly attributable to the subject properties. There could exist
other revenues, overhead costs, or other costs associated with TVOC.
Such additional costs and revenues are outside the scope of this
report. This report is not a financial statement for TVOC and
should not be used as the sole basis for any transaction concerning
TVOC. In this report, Miller expresses no opinion as to the fair
market value of the evaluated interests.

Miller is an independent consulting petroleum engineer and does
not own an interest in the evaluated properties or any interest
in TVOC. Millers compensation for the preparation of this report
is not contingent upon or subject to the results of this
evaluation.

Reserves were evaluated and classified according to the attached
Definitions of Oil and Gas Reserves for evaluations prepared for
disclosure to the Securities and Exchange Commission (SEC).

Miller utilized industry-accepted methods of engineering in
preparing the projections of oil and gas reserves estimates
included in this evaluation. However, it should be noted that the
estimates of oil and gas reserves carry any inherently high
degree of risk due to the uncertainties in the interpretation
and quality of the available historical data.

Miller reserves the right to revise the estimates and associated
economics contained herein without notice based on any revisions
to the data utilized or any subsequent event that would in the
opinion of Miller, cause a material change in those estimates.
These estimates are being furnished with the understanding that
revisions may be required in the future as a result of future
performance, operational changes, and changes in product prices
and taxes.

Current oil and gas production was obtained from the Railroad
Commission of Texas (TRRC).  Furthermore, Miller utilized
historical production data obtained from the TRRC and a standard
information source considered reliable by the Oil and Gas
Industry. All of the data was accepted as correct and utilized
by Miller in the preparation of this report. Miller expresses no
opinion as to the validity of the above information used for the
basis of this evaluation.

Miller did not perform on-site operational and environmental
reviews of the individual properties in this evaluation. These
investigations were considered outside the scope of services
requested.

PRICES AND COSTS

An oil price of $79.43 per barrel based on a New York Mercantile
Exchange price (NYMEX) was utilized as the base oil price as of
the effective date.  This base price represents the average of the
closing price for light sweet crude oil traded on NYMEX on the
first day of the month for each month in 2010. If the first day

of the month fell on a weekend or holiday, then the prior trading
day closing price was used in the average.  The base oil price
was adjusted for each evaluated property, and the adjustments came
from average historical differentials between the actual prices
received by each property and the average NYMEX prices for the
month for months from December 2009 through November 2010. Oil
price data was provided by TVOC on the properties from December
2009 through November 2010.  The base oil price plus or minus
the applicable price differential for each individual property
was held constant through the economic life of the property.

A gas price of $4.45 per MMBTU of natural gas based on a
New York Mercantile Exchange price (NYMEX) was utilized as
the base gas price. This base price represents the average
of the closing price of natural gas traded on NYMEX on the
first day of the month for each month in 2010. If the first
day of the month fell on a weekend or a holiday, then the prior
trading day closing price was used in the average. The base
gas price was adjusted for each evaluated property for BTU
content, compression and treating, and contract terms, and
the adjustments came from average historical ratios between the
actual prices received by each property and the average NYMEX
prices for the month for months from November 2009 and
October 2010. Gas price data was provided by TVOC on the
properties from November 2009 through October 2010. The base
gas price multiplied by this ratio for each individual property
was held constant through the economic life of the property.

TVOC provided Lease operating expenses (LOEs) for all of
2010 on the operated properties and the non-operated
properties. The lease operating expenses (LOEs) were
adjusted for nonrecurring items and averaged for the
months included. LOEs include normal repairs and maintenance
such as pulling jobs and chemicals.  LOEs were held
constant for the economic live of the properties.

The evaluated interests also include royalty and overriding
royalty interests.  These royalty interests are not
subject to operating expenses. However, economic lifetimes
were calculated for each property by estimating abandonment
rates for the evaluated properties. Based on experience,
the abandonment rates are representative of the wells in
the field.

State production and ad valorem taxes were deducted at
published rates as applicable.

PROPERTY REVIEW

This evaluation includes engineering projections of proved
developed producing oil and gas reserves for 325 wells on
266 leases. The estimated reserves are 55.5% oil based
on barrels of oil equivalent and the estimated future net
revenue is 73.8% oil based on future net sales. The most
valuable property, the Zimmerhanzel #1RE, accounts for
4.0% of the future net revenue discounted at 10%. The
Zimmerhanzel #1RE is located in the Giddings (Austin
Chalk-3)field in Fayette, County, Texas and is operated
by Lama Energy LLC. TVOC owns a 0.1250 Working Interest
(WI) and a 0.09625 Net Revenue Interest (NRI) in the
well. The well began producing in January 2010 and has
cumulative production of 42,938 Bbl. of oil and 19,686
Mcf of gas through December 2010. There is an inherent
degree of risk with wells with a short production history.
However, projections of future reserves on the
Zimmerhanzel #1RE were based on performance and analogies
to offset wells.  In addition, the remaining evaluated
leases exhibit mature and stable decline trends and
projections of oil and gas reserves were based on
extrapolation of historical decline trends.

Of the 325wells evaluated, 234 are operated by TVOC and
represent 81.6% ($11,245.7M) of the future net revenue
discounted at 10%.


It has been a pleasure in preparing this evaluation. All
