Dear Ms. Hanes:

     At your request, LaRoche Petroleum Consultants, Ltd. (LPC) has estimated the proved developed producing reserves and future cash flow, as of December 31, 2010, to the NYTEX Petroleum, Inc. (NYTEX) interest in certain properties located in Archer, Hutchinson, Leon, Liberty and Moore counties, Texas. The work in this report was completed as of the date of this letter. This report was prepared to provide NYTEX with Securities and Exchange Commission (SEC) compliant reserve estimates. It is our understanding that the properties evaluated by LPC comprise one hundred percent (100%) of NYTEX’s proved developed producing reserves. We believe that the assumptions, data, methods, and procedures used in preparing this report, as set out below, are appropriate for the purpose of this report. This report has been prepared using constant prices and costs and conforms to our understanding of the SEC guidelines, reserves definitions, and applicable financial accounting rules.

     Summarized below are LPC’s estimates of net reserves and future net cash flow. Future net cash flow is after deducting operating expenses, and future capital expenditures, but before consideration of federal income taxes. The discounted cash flow values included in this report are intended to represent the time value of money and should not be construed to represent an estimate of fair market value. We estimate the net reserves and future net cash flow to the NYTEX interest, as of December 31, 2010, to be:

     The oil reserves include crude oil, condensate, and natural gas liquids (NGL). Oil and NGL reserves are expressed in barrels, which are equivalent to 42 United States gallons. Gas reserves are expressed in thousands of standard cubic feet (Mcf) at the contract temperature and pressure bases.

     The estimated reserves and future cash flow shown in this report are for proved developed producing reserves. This report does not include any value that could be attributed to interests in undeveloped acreage.

     This report includes: (1) summary economic projections of reserves and cash flow for each reserve category, (2) one-line summaries of basic economic data and reserves for each property evaluated, and (3) economic projections of reserves and cash flow for each evaluated property.

     Estimates of reserves for this report were prepared using standard geological and engineering methods generally accepted by the petroleum industry. The reserves in this report have been estimated using deterministic methods. The method or combination of methods utilized in the evaluation of each reservoir included consideration of the stage of development of the reservoir, quality and completeness of basic data, and production history. Recovery from various reservoirs and leases was estimated after consideration of the type of energy inherent in the reservoirs, the structural positions of the properties, and reservoir and well performance. In some instances, comparisons were made to similar properties for which more complete data were available. We have used all methods and procedures that we considered necessary under the circumstances to prepare this report. We have excluded from our consideration all matters as to which the controlling interpretation may be legal or accounting rather than engineering or geoscience.

     The estimated reserves and future cash flow amounts in this report are related to hydrocarbon prices. Historical prices through December 31, 2010 were used in the preparation of this report as required by SEC guidelines; however, actual future prices may vary significantly from the SEC prices. In addition, future changes in environmental and administrative regulations may significantly affect the ability of NYTEX to produce oil and gas at the projected levels. Therefore, volumes of reserves actually recovered and amounts of cash flow actually received may differ significantly from the estimated quantities presented in this report.

     Benchmark prices used in this report are based on the twelve-month un-weighted arithmetic average of the first day of the month price for the period January through December 2010. Gas prices are referenced to a Henry Hub (HH) price of $4.38 per MMBtu, as published in Platts Gas Daily, and are adjusted for energy content, transportation fees, and regional price differentials. Oil and NGL prices are referenced to a West Texas Intermediate (WTI) crude oil price of $75.96 per barrel, as posted by Plains Marketing, L.P., and are adjusted for gravity, crude quality, transportation fees, and regional price differentials. These reference prices are held constant in accordance with SEC guidelines. The weighted average prices after adjustments over the life of the properties are $75.15 per barrel for oil, $4.37 per mcf for gas, and $52.66 per barrel for NGL.

     Lease and well operating expenses are based on data obtained from NYTEX. Expenses for the properties operated by NYTEX include allocated overhead costs, direct lease and field level costs as well as compression costs and marketing expenses. Leases and wells operated by others include all direct expenses as well as general and administrative costs and overhead costs allowed under the specific joint operating agreements. Lease and well operating costs are held constant in accordance with SEC guidelines.

     Estimates of the cost to plug and abandon the wells net of salvage value have been provided by NYTEX and are included and scheduled at the end of the economic life of individual properties. These costs are held constant.

     LPC has made no investigation of possible gas volume and value imbalances that may have resulted from the overdelivery or underdelivery to the NYTEX interest. Our projections are based on the NYTEX interest receiving its net revenue interest share of estimated future gross oil and gas production.

LaRoche Petroleum Consultants, Ltd.

     Technical information necessary for the preparation of the reserve estimates herein was furnished by NYTEX or was obtained from state regulatory agencies and commercially available data sources. No special tests were obtained to assist in the preparation of this report. For the purpose of this report, the individual well test and production data as reported by the above sources were accepted as represented together with all other factual data presented by NYTEX including the extent and character of the interest evaluated.

     An on-site inspection of the properties has not been performed nor has the mechanical operation or condition of the wells and their related facilities been examined by LPC. In addition, the costs associated with the continued operation of uneconomic properties are not reflected in the cash flows.

     The evaluation of potential environmental liability from the operation and abandonment of the properties is beyond the scope of this report. In addition, no evaluation was made to determine the degree of operator compliance with current environmental rules, regulations, and reporting requirements. Therefore, no estimate of the potential economic liability, if any, from environmental concerns is included in the projections presented herein.

     The reserves included in this report are estimates only and should not be construed as exact quantities. They may or may not be recovered; if recovered, the revenues therefrom and the costs related thereto could be more or less than the estimated amounts. These estimates should be accepted with the understanding that future development, production history, changes in regulations, product prices, and operating expenses would probably cause us to make revisions in subsequent evaluations. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geological data; therefore, our conclusions represent informed professional judgments only, not statements of fact.

     The results of our third party study were prepared in accordance with the disclosure requirements set forth in the SEC regulations and intended for public disclosure as an exhibit in filings made with the SEC by NYTEX.

     NYTEX makes periodic filings on Form 10-K with the SEC under the 1934 Exchange Act. Furthermore, NYTEX has certain registration statements filed with the SEC under the 1933 Securities Act into which any subsequently filed Form 10-K is incorporated by reference. We have consented to the incorporation by reference in the registration statements on Form S-3 and Form S-8 of NYTEX of the references to our name, together with references to our third party report for NYTEX which appears in the December 31, 2010 annual report on Form 10-K and/or 10-K/A of NYTEX. Our written consent for such use is included as a separate exhibit to the filings made with the SEC by NYTEX.

     We have provided NYTEX with a digital version of the original signed copy of this report letter. In the event there are any differences between the digital version included in filings made by NYTEX and the original signed report letter, the original signed report letter shall control and supersede the digital version.
