Dear Mr. Mundy:

At your request, LaRoche Petroleum Consultants, Ltd. (LPC) has estimated the proved reserves and future cash flow, as of December 31, 2011, to the Quicksilver Resources Canada, Inc. (QRCI) interest in certain properties located in Alberta and British Columbia, Canada. QRCI is a wholly owned subsidiary of Quicksilver Resources, Inc. (Quicksilver). The work in this report was completed as of January 27, 2012. This report was prepared to provide Quicksilver with Securities and Exchange Commission (SEC) compliant reserve estimates. It is our understanding that the properties evaluated by LPC comprise 100 percent (100%) of QRCI’s proved reserves located in Canada. 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. All prices, costs, and cash flow estimates are expressed in United States dollars (US$).

It is our understanding that LPC evaluated approximately 12.0 percent (12.0%) of Quicksilver’s total proved reserves, that additional properties were audited or estimated by other consultants, and that the total of the audited and estimated properties by all consultants constitutes one hundred percent (100%) of Quicksilver’s aggregate reserves as estimated and reported by Quicksilver.

Summarized below are LPC’s estimates of net reserves and future net cash flow. Future net revenue is after deducting estimated Crown and freehold royalties but prior to deducting freehold mineral taxes. Future net cash flow is after deducting freehold mineral taxes, operating expenses, future capital expenditures, and abandonment 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 QRCI interest, as of December 31, 2011, to be:

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

The estimated reserves and future cash flow shown in this report are for proved developed producing reserves and, for certain properties, proved developed non-producing, and proved undeveloped reserves. This report does not include any value that could be attributed to interests in undeveloped acreage beyond those tracts for which undeveloped reserves have been estimated.

Both gross and net gas reserves presented in this report are after shrinkage. All prices, revenues, expenses, and cash flows referenced in this report are in United States (US) dollars which have been converted from Canadian currency using the December 31, 2011 exchange rate of 0.9833 US$ to CAN$.

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

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 2011 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 QRCI 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 unweighted arithmetic average of the first day of the month price for the period January through December 2011. Gas prices are referenced to an AECO price of US$3.65 per MMBtu, as published in the 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 US$95.71 per barrel at Cushing Oklahoma, 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 US$90.25 per barrel of oil, US$3.19 per mcf of gas, and US$76.31 per barrel of NGL.

Lease and well operating expenses are based on data obtained from QRCI. Expenses for the properties operated by QRCI include allocated overhead costs, direct lease and field level costs as well as compression costs and marketing expenses. 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.

Capital costs and timing of all investments have been provided by QRCI and are included as required for workovers, new development wells, and production equipment. QRCI has represented to us that they have the ability and intent to implement their capital expenditure program as scheduled. Estimates of the cost to plug and abandon the wells net of salvage value 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 QRCI interest. Our projections are based on the QRCI interest receiving its net revenue interest share of estimated future gross oil and gas production.

Technical information necessary for the preparation of the reserve estimates herein was furnished by QRCI or was obtained from provincial 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 QRCI 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. A portion of these reserves are for behind-pipe zones, undeveloped locations, and producing wells that lack sufficient production history to utilize performance-related reserve estimates. Therefore, these reserves are based on estimates of reservoir volumes and recovery efficiencies along with analogies to similar production. These reserve estimates are subject to a greater degree of uncertainty than those based on substantial production and pressure data. It may be necessary to revise these estimates up or down in the future as additional performance data become available. 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.
