Tuesday, February 8, 2011

CALGARY, Canada, February 9, 2011 - Perpetual Energy Inc. ("Perpetual" or the "Corporation") is pleased to
confirm that its dividend to be paid on March 15, 2011 in respect of income
received by Perpetual for the month of February 2011, for shareholders of
record on February 23, 2011, will be $0.03 per share. The ex-dividend date is
February 18, 2011. The February 2011 dividend brings cumulative dividends
(including distributions paid since the inception of Perpetual's predecessor,
Paramount Energy Trust) to $14.384 per share. Perpetual reviews dividends on
a monthly basis. Future dividends are subject to change as dictated by
commodity price markets, operations, capital considerations and future
business development opportunities.

The Corporation also advises that there will continue to be no shares
available under either the Premium DividendTM or dividend reinvestment
component of the Premium DividendTM and Dividend Reinvestment Plan (the
"Plan") for the Corporation's February 2011 dividend payable on March 15,
2011
and until further notice. At such time as the Corporation elects to
reinstate either or both components of the Plan, shareholders who were
enrolled at suspension and remain enrolled at reinstatement will
automatically resume participation in the Plan.

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.

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.

RESERVE LIFE INDEX ("RLI")

Perpetual's proved and probable reserves to production ratio, also
referred to as reserve life index, was 8.4 years at year-end 2010 while the
proved RLI was 4.8 years, based upon the 2011 production estimates in the
McDaniel Report. The following table summarizes PET's historical calculated
RLI.

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.

(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.

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:

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.

added back into the total reserve additions and revisions. (5) 22.3 Bcf of
proved and probable reserves associated with price related revisions have

ratio of 1 bbl: 6 Mcf is based on an energy equivalency conversion method
primarily applicable at the burner tip and does not represent a value
equivalency at the wellhead.
