YEAR-END 2010 RESERVES

The Corporation is pleased to release a summary of the company's year-end 2010 reserves information, as evaluated by the independent engineering firm McDaniel and Associates Consultants Ltd. ("McDaniel").

Year-End Reserve Highlights

- In 2010, Perpetual added 40.0 Bcfe of proved and probable reserves, excluding production. - After dispositions of 53.1 Bcfe and production of 55.9 Bcfe in 2010, proved and probable reserves decreased three percent from 471.6 Bcfe at year-end 2009 to 455.6 Bcfe and proved reserves decreased three percent to 235.9 Bcfe at year-end 2010. - Excluding downward revisions related solely to changes in natural gas pricing at year-end 2010 of 22.3 Bcfe, Perpetual's reserves grew one percent year over year from 471.6 Bcfe to 477.9 Bcfe, offsetting production of 55.9 Bcfe and net dispositions of 9.8 Bcfe, which included the disposition of 34.2 Bcf of probable shut-in gas over bitumen reserves where the effective funds flow through the Government of Alberta's financial solution was retained by Perpetual. - Reserve additions largely offsetting production and dispositions were a result of total net capital spending of $163.2 million, including investment of $114.1 million in exploration and development capital spending programs excluding spending for the development of Perpetual's gas storage asset at Warwick ("Warwick Gas Storage"), as well as various asset acquisitions in the Edson and Birchwavy areas during the year. - Including changes in future development capital ("FDC"), Perpetual realized finding and development costs ("F&D") of $1.87 per Mcfe ($11.22 per BOE) on a proved and probable reserve basis in 2010. - Perpetual's realized finding, development and acquisition costs ("FD&A"), including changes in FDC, was $2.49 per Mcfe ($14.94 per BOE) on a proved and probable basis. FD&A costs were significantly impacted by relatively low disposition metrics on a reserve basis associated with the sale of probable shut-in gas over bitumen reserves without the related effective funds flow from future royalty reductions in the Legend, Liege and Surmont areas of 34.2 Bcf for net proceeds of $39.8 million. Perpetual retained the effective funds flow for these shut-in gas over bitumen reserves making the asset sales incomparable to other transactions, therefore the proceeds and reserves associated from these dispositions have been removed for purposes of the FD&A calculation. - No reserves were recorded at year-end 2010 for the Corporation's extensive acreage position and three gross (1.4 net) horizontal wells penetrating the Montney formation at Elmworth. An independent contingent resource assessment report was prepared by McDaniel for 42 gross sections of Perpetual's Montney acreage in the Elmworth area which on a preliminary basis estimates gross original gas in place ("OGIP") on company interest lands of 987.5 Bcf plus associated natural gas liquids ("NGLs"). Assuming a range in recovery factors from 20 to 50 percent, gross recoverable sales gas is estimated from a low of 167.9 Bcf with 5.9 MMbbls of NGLs (203.4 Bcfe) to a high of 419.7 Bcf with 24.7 MMbbls NGLs (567.8 Bcfe), with McDaniel's best estimate at 35 percent recovery factor translating to 293.8 Bcf with 13.8 MMbbls NGLs (376.7 Bcfe). On a working interest basis, the best estimate recoverable contingent resource is estimated at 177.9 Bcfe. Perpetual has an additional 34 gross sections in the Elmworth area which have not yet been evaluated through drilling in the Montney formation. - Perpetual's reserve to production ratio ("reserve life index" or "RLI") is 8.4 years on a proved and probable reserves basis (4.8 years on a proved reserves basis) at year-end 2010. - Perpetual's reserve-based net asset value ("NAV") at year-end 2010 was estimated at $5.02 per Share discounted at eight percent.

Reserves Disclosure

Company interest reserves included herein are before royalty burdens and including royalty interests. Reserves information is based on an independent reserves evaluation report prepared by McDaniel dated February 7, 2011 with an effective date of December 31, 2010 (the "McDaniel Report"), and has been prepared in accordance with National Instrument 51-101 ("NI 51-101") using McDaniel's forecast prices and costs. Complete NI 51-101 reserves disclosure including after-tax reserve values, reserves by major property and abandonment costs will be included in Perpetual's Annual Information Form ("AIF"), which will be filed in March 2011.

Approximately 94 percent of Perpetual's proved and proved and probable reserves are natural gas and as such the Corporation reports reserves in Mcf equivalent (Mcfe). Mcfe may be misleading, particularly if used in isolation. In accordance with NI 51-101 a Mcfe conversion ratio for oil of 1 Bbl: 6 Mcf has been used, which is based on an energy equivalency conversion method primarily applicable at the burner tip and does not necessarily represent a value equivalency at the wellhead.

Perpetual's reserves at year-end 2010 are summarized below.

The proved producing reserves comprise 85 percent of the total proved reserves and 44 percent of the total proved and probable reserves, while proved and probable developed producing reserves are 60 percent of the total proved and probable reserves. Total proved reserves account for 52 percent of the total proved and probable reserves. McDaniel estimates the FDC required to convert non-producing and undeveloped reserves to producing reserves at $236.4 million.

Perpetual disposed of 34.2 Bcfe of proved and probable reserves associated with natural gas interests in the Legend, Liege and Surmont areas that were shut-in as a result of the gas over bitumen regulatory issue. Perpetual retained the effective funds flow from the reduction of future royalties related to the financial solution in place for the shut-in gas and this is reflected in proven future net revenues.

Year over year, McDaniel recorded net positive technical revisions totaling 27.4 Bcfe on a proved and probable basis. These positive revisions were due to improved performance and improved operating costs in all areas. These positive revisions were offset by a substantially reduced price forecast at year-end 2010 relative to year-end 2009 resulting in negative revisions of 22.3 Bcfe due to increased economic limits which primarily affected the forecast for wells as they neared their end of productive life. Included in the downward price revisions are those future projects whose return on investment at the current price forecast results is negative.

McDaniel's price forecast utilized in the evaluation is summarized below.

NET PRESENT VALUE ("NPV") OF RESERVES SUMMARY

Perpetual's light and medium oil, natural gas and natural gas liquids reserves were evaluated by McDaniel using McDaniel's product price forecasts effective January 1, 2011 prior to provision for financial natural gas price hedges, income taxes, interest, debt service charges and general and administrative expenses. The following table summarizes the net present value of funds flows from recognized reserves at January 1, 2011, assuming various discount rates. It should not be assumed that the discounted future net funds flows estimated by McDaniel represent the fair market value of the potential future production revenue of the company.

At a 10 percent discount factor, the proved producing reserves comprise 60 percent of the total proved and probable value while proved and probable developed producing reserves represent 74 percent of the total proved and probable value. Total proved reserves account for 64 percent of the proved and probable value.

CONTINGENT RESOURCE

A preliminary resource assessment was conducted for the Montney Formation in the Elmworth area by McDaniel as at year-end 2010, the results of which are summarized below.

Contingent Resource(1,4) Working Interest Recoverable Recoverable Recoverable Original Raw Sales Natural Natural Natural Gas in Recoverable Recoverable Gas Gas Gas Place Gas (3) Gas Liquids Equivalent Equivalent (MMcf) (MMcf) (MMcf) (Mbbl) (MMcfe) (MMcfe) Low (2) 987,470 197,494 167,870 5,925 203,419 96,100 Best (2) 987,470 345,615 293,770 13,825 376,718 177,900 High (2) 987,470 493,735 419,680 24,687 567,801 268,200

(1) Contingent resources have been evaluated by McDaniel using the definitions is as defined in section five of the Canadian Oil and Gas Evaluators Handbook, Volume 1. All volumes are reported before the deduction of royalties payable to others. Contingent resource assignments are in addition to any reserve assignments associated with these assets. (2) A Low estimate (90% chance the ultimate recoverable resource will be equal or greater than the stated value), means higher certainty, a Best estimate (50% chance that the ultimate recoverable resource will be greater than or equal to the stated value) means most likely and a High estimate means lower than a 50% chance that the ultimate recoverable resource will be greater than or equal to the stated value (3) McDaniel has assigned recovery factors of 20% (Low), 35% (Best) and 50% (High) in their assessment of recoverable resource. (4) Contingent resources can be sub-classified into economic and uneconomic portions based on a number of assumptions on capital costs, timing, price forecast, etc. Currently sub-classification of these preliminary estimates has not been completed pending a discussion of the above parameters.

The primary contingencies identified for the Montney resource are infrastructure and access to market. Once development plans are in place which can define a commercial project, it is expected that a portion of these estimates would shift into proved and probable reserves subject to standard booking practice for undeveloped reserves.

NET ASSET VALUE ("NAV")

The following net asset value table shows what is normally referred to as a "produce-out" NAV calculation under which the Corporation's reserves would be produced at forecast future prices and costs. The value is a snapshot in time and is based on various assumptions including commodity prices and foreign exchange rates that vary over time. It should not be assumed that the NAV represents the fair market value of Perpetual Shares. The calculations below do not reflect the value of the Corporation's prospect inventory to the extent that the prospects are not recognized within the NI-51-101 compliant reserve assessment.

Of particular note, there are no reserves assigned to the company's Elmworth Montney project where three gross (1.4 net) horizontal wells estimate have been drilled by Perpetual and its partners. McDaniel has recognized as its best case, contingent recoverable resource of 178 Bcfe to Perpetual's working interest lands. Development scenarios for the over one Tcfe of natural gas and NGLs in place in the Montney at Elmworth will be evaluated by Perpetual and its partners in 2011. In addition, no reserves or contingent resources are yet assigned to any of Perpetual's heavy oil projects in northeast Alberta. The incremental value of Perpetual's extensive prospect inventory for its game-changing opportunities in the Montney at Elmworth, Cardium light oil at Carrot Creek, Wilrich liquids-rich gas at Edson, the Colorado shallow shale gas in east central Alberta and the bitumen projects in northeast Alberta, above the nominal amount which is currently recognized by McDaniel, is captured only through the assessment of the fair market value of undeveloped land based on current land sale valuation parameters.

Of further note, the value of the Corporation's Warwick Gas Storage asset has been recorded at cost in the net asset value calculation below. Construction of the Warwick Gas Storage facility was completed in the fourth quarter of 2010 and withdrawal has now commenced on the preliminary test cycle which will be complete at the end of March 2011. Information gathered during the test cycle will define the developed working gas capacity of the storage reservoir at that time. This in turn will lead to a more comprehensive valuation of the asset.

(7) Value of Perpetual's open hedging transactions related to the Warwick Gas Storage funding arrangement at year end 2010 assuming settlement against the McDaniel price forecast.

In the absence of adding reserves to the Corporation, the NAV per share will decline as the reserves are produced out. The funds flow generated by the production relates directly to the cash dividends paid to Perpetual shareholders. The above evaluation includes future capital expenditure expectations required to bring undeveloped reserves recognized by McDaniel that meet the criteria for booking under NI 51-101 on production.

FAIR MARKET VALUE OF UNDEVELOPED LAND

Perpetual's third party estimate of the fair market value of its undeveloped acreage by region for purposes of the above net asset value calculation is based on recent Crown land sale activity adjusted for tenure and other considerations and is as follows:

Fair Market Value of Undeveloped Land Area Acres Total Value ($) $/Acre North 1,000,197 $41,042,433 $41.03 South 405,289 $59,761,578 $147.45 West Central 140,978 $66,848,275 $474.18 New Ventures 25,350 $8,607,925 $339.56 Heavy Oil 333,259 $27,809,494 $83.45 Totals 1,905,073 204,069,705 $107.12

ABANDONMENT AND RECLAMATION COSTS

In addition to the abandonment cost estimates provided by McDaniel inclusive in their reserve assessment, Perpetual compiles annually a detailed internal estimate of the Corporation's total future asset retirement obligation based on net ownership interest in all wells, facilities and pipelines, including estimated costs to abandon the wells, facilities and pipelines and reclaim the sites, and the estimated timing of the costs to be incurred in future periods. Pursuant to this evaluation, the estimated value of Perpetual's future asset retirement obligations, net of the estimated salvage value of facilities and equipment and discounted at 8 percent is $74 million as at December 31, 2010. The McDaniel Report includes an undiscounted amount of $83 million with respect to expected future well abandonment costs related specifically to proved and probable reserves and such amount is included in the values captioned "Total Proved and Probable Reserves" in the NPV of Funds Flow table (see "NET PRESENT VALUE ("NPV") OF RESERVES SUMMARY"). Of the total future well abandonment costs included in the McDaniel Report an undiscounted amount of $56 million relates to Perpetual's developed reserves. The following table presents the estimated future asset retirement obligations and estimated net salvage values at various discount rates:

FINDING, DEVELOPMENT AND ACQUISITION ("FD&A") COSTS

Under NI 51-101, the methodology to be used to calculate FD&A costs includes incorporating changes in future development capital required to bring the proved undeveloped and probable reserves to production. For continuity, Perpetual has presented herein FD&A costs calculated both excluding and including FDC. Changes in forecast FDC occur annually as a result of development activities, acquisitions and disposition activities and capital cost estimates that reflect the independent evaluator's best estimate of what it will cost to bring the proved undeveloped and probable reserves on production. The decrease in FDC is the result of projects being deemed to be uneconomic under the current McDaniel price forecast. Perpetual believes that the underlying resource is still present and those projects will be added back if natural gas prices increase in the future.

The following table summarizes Perpetual's F&D cost as well as finding, development and acquisition costs, before and after the inclusion of changes in FDC. Finding and development costs, including changes in FDC were $1.87 per Mcfe ($11.22 per BOE) on a proved and probable basis in 2010.

The same metrics are presented below with the impact of the sale of probable shut-in gas over bitumen reserves in the Legend, Liege and Surmont areas removed, as the dispositions are not comparable to other acquisitions and dispositions since Perpetual retained the effective funds flow related to the Government of Alberta's gas over bitumen financial solution through royalty reductions associated with the shut-in properties. Including changes in FDC, FD&A costs were $2.49 per Mcfe ($14.94 per BOE) on a proved and probable basis.

Perpetual has also summarized in the table below these same metrics with the effect of the price-related revisions removed. Perpetual believes that the majority of these reserves will return to the books with a recovery in natural gas prices as the technical merits for booking the reserves have not changed, only the economic circumstances. Excluding the effects of negative reserve revisions related to substantially lower forward gas prices, including changes in FDC, Perpetual's F&D costs were $1.30 per Mcfe ($7.80 per BOE) for proved and probable reserves and FD&A costs were $1.91 per Mcfe ($11.46 per BOE) in 2010 on a proved and probable basis.
